Myotonia is a clinical sign characterized by the delay of skeletal muscle relaxation following the cessation of a voluntary activity or the termination of an electrical or mechanical stimulus. Recently, Miniature Schnauzers with myotonia congenita associated with defective chloride ion conductance across the skeletal muscle membrane were identified. Congenital myotonia in these dogs appears to follow an autosomal recessive mode of inheritance. Craniofacial and dental findings of eight Miniature Schnauzer dogs with myotonia congenita are described in the present paper. These findings include: delayed dental eruption of both deciduous and permanent dentition: persistent deciduous dentition; unerupted or partially erupted permanent teeth: crowding and rotation of premolar and or incisor teeth: missing teeth: increased interproximal space between the maxillary fourth premolar and first molar teeth: decreased interproximal space between the maxillary canine and lateral incisor teeth: inability to fully close the mouth due to malocclusion: distoclusion: and, decreased mandibular range of motion. A long narrow skull with a flattened zygomatic arch and greater mandibular body curvature were also consistent findings in the affected dogs. The small number of dogs studied prevents conclusive statements about the origin of these abnormalities, however it is interesting that only 1 of 45 unaffected Miniature Schnauzer dogs showed similar traits.

The purpose of this study was to investigate the prevalence of peg-shaped maxillary lateral incisors and the incidence of associated dental anomalies in children. We investigated the prevalence of peg-laterals and incidence of associated dental anomalies in 3,834 children aged 7-15 who visited the Department of Pediatric Dentistry from January 2010 to December 2015 and underwent panoramic radiographs. The prevalence of peg-laterals was 1.69% in boys, 1.75% in girls, and 1.72% overall. Among children with peg-laterals, the frequencies of associated dental anomalies were as follows: congenitally missing teeth, 31.8%; dens invaginatus, 19.7%; palatally displaced canines, 12.1%; supernumerary teeth, 7.6%; and transposition, 7.6%. As children with peg-laterals have a higher incidence of other dental anomalies, careful consideration is needed when planning diagnosis and treatment.

The purpose of this study was to evaluate the prevalence of various congenital dental anomalies in the permanent dentition of Turkish children with Down syndrome. The sample consisted of 216 diagnostic records of children diagnosed with Down syndrome. All subjects had a clinical examination as well as radiographs and photographs taken. Anomalies in the permanent dentition were documented. There was a high incidence of dental anomalies, the most frequent being taurodontism (81 percent), rotation (28 percent), hypodontia (26 percent), tooth impaction (18 percent), ectopic eruption (14 percent), microdontia (13 percent), and hyperdontia (9 percent). Differences in prevalence of congenitally missing teeth, structural anomalies, and positional anomalies reached a statistically significant level regarding gender (P<.05). Turkish children with Down syndrome presented a high incidence of anomalies affecting the permanent dentition, and, in most cases, individuals presented with more than one anomaly.

To determine the impact of hypodontia on the quality of life of adolescent and young adult patients, and, to assess the impact of restoring tooth spaces with resin bonded bridgework on quality of life of patients with hypodontia. In a prospective study, 82 patients with a confirmed diagnosis of hypodontia participated. The primary outcome was oral health related quality of life (OHRQoL) and this was measured using the OHIP-49 prior to treatment. The pre-treatment sample was then divided into two groups: the test group (n=40 patients) who had completed orthodontic treatment and had tooth spaces restored with resin bonded bridgework, and, a control group (n=42 patients) who were still in the process of orthodontic treatment. All patients completed a follow-up OHIP-49, and between and within group comparisons made. The pre-treatment sample included 43 females and 39 males, age ranged from 16 to 34 years (median age 19). Forty-three patients had more than 4 congenitally missing teeth and thirty-nine had ≤ 4 congenitally missing teeth. There were no differences between the groups prior to treatment. For the test group, there was a significant improvement in median OHIP summary scores (p<0.001) after treatment. OHIP scores deteriorated to a significant degree for control subjects (p=0.002). The effect sizes for the pre-post treatment change in both groups were moderate to large. Hypodontia has a significant impact on oral health related quality of life. Provision of resin bonded bridges has a positive impact on oral health related quality of life of patients with hypodontia. Copyright © 2013 Elsevier Ltd. All rights reserved.

Congenitally missing teeth (CMT) are of concern to many fields of dentistry. Only a few reviews have been published in this regard. The aim was to analyze the literature on CMT in the permanent dentition, excluding the third molars, and to identify potential links with ethnicity, geographical regions, and time. A total of 118 reports on CMT were collected by two authors by interrogating databases. Sample homogeneity, publication bias, publication year (in Caucasian and Mongoloid samples, and in general), ethnicities, and geography of CMT prevalence were statistically analyzed using a Q-test, Egger regression, linear regression, a Spearman coefficient, Kruskal-Wallis, a Dunn post-hoc (α = 0.05), and a Mann-Whitney U test (α = 0.0125, α = 0.0071). The mean CMT prevalence was 6.53% ± 3.33%. There were significant geographic differences in CMT rates (P = 0.0001, Kruskal-Wallis) and between ethnicities (P = 0.0002, Kruskal-Wallis). According to the Mann-Whitney U test (α = 0.0071), eastern Asians (P = 0.0008) and Europeans (marginally significant, P = 0.0128) showed an elevated prevalence, while Western Asians (P = 0.0001) and Americans (marginally significant, P = 0.0292) had lower prevalence rates. Compared with other ethnicities, Mongoloids showed higher prevalence (P = 0.0009) while Asian Caucasians showed lower rates (P = 0.0005, Mann-Whitney U, α = 0.0125). The year of publication was not significantly correlated with any of the subsamples studied (P > 0.3, linear regression). Clinicians should be vigilant in the assessment of CMT in Mongoloids. No increase of this condition was detected during the last century. Copyright © 2015 CEO. Published by Elsevier Masson SAS. All rights reserved.

A new glass-ceramic material, IPS Empress 2, is revolutionizing esthetic restorative dentistry by allowing metal-free, three-unit bridge construction in anterior and premolar single-pontic areas. The case discussed in this article illustrates the material's application in the dual-arch restoration of a young woman with congenitally missing teeth. The material was used as an alternative to single-tooth implant restorations to place two maxillary three-unit bridges, one mandibular three-unit bridge, and two mandibular porcelain veneers. IPS Empress 2 provides an esthetic alternative to porcelain-fused-to-metal restorations by facilitating attractive, functional tooth restoration.

Based on the research of the congenital missing of the third molar and the missing number, the relationship beteen congenital missing of the third molar and the development of the mandibular angle was evaluated. Patients were divided into experimental group and control group, the experimental group included 227 patients, each had at least one of the third molars congenital lost; 227 patients who had four third molar were selected as control group. Winceph software was used to measure the lateral cephalograms. SPSS17.0 software package was used to perform statistical analysis. Gonial angle, upper Gonial angle and lower Gonial angle between the experimental group and the control group showed significant difference and the values in the experimental group were significantly smaller than in the control group, but there was no gender difference between the two groups.There was no difference between Gonial angle, upper Gonial angle,lower Gonial angle and the missing number of the third molar. There is a close relationship between congenital missing third molar and Gonial angle, upper Gonial angle, lower Gonial angle, but there is no significant association with gender and the patients with congenital missing third molar have shorter craniofacial structure. Congenital missing number of the third molar has no significant association with Gonial angle, upper Gonial angle and lower Gonial angle.

Various causes of tooth loss such as caries, trauma, periodontal diseases, and cancer have been documented in the literature. In addition, factors that can modify these causes such as level of education, age and sex have been studied. There is however paucity of information on whether patients or people with missing teeth are aware of the side effects of tooth loss on them or on the remaining teeth. This study investigated the knowledge of consequences of missing teeth among partially edentulous patients in a teaching hospital. Self-administered questionnaires were distributed to the patients to collect information relating to demography, cause and duration of tooth loss, awareness of the consequences of tooth loss and their sources of information. Four clinical conditions including supra-eruption, mastication, teeth drifting, and facial collapse were used to assess the level of awareness of consequences of missing teeth. Two hundred and three participants were included in the study. Their mean age was 45.5±1.8 years. There was no significant difference between the knowledge of the consequences of missing teeth and sex or on level of education (p(·) 0.05). Dentists constituted the largest source of information to these patients (25.6%) while the media constituted the least (0.5%). The result of this study showed poor knowledge of the consequences of missing teeth among partially edentulous patients and the media that should be of assistance were equally unaware, signifying urgent need for public awareness on this subject.

Background Cleft defects are one of the most frequent birth-deformities of the orofacial region and they are commonly associated with anomalies of the tooth structure, size, shape, formation, eruption, and tooth number. The aim of our study was to evaluate the prevalence, distribution, and potential association of combined hypodontia in cleft-affected patients with regard to all types of teeth in both jaws in the permanent dentition. Material/Methods This retrospective radiographic analysis included patients with various types of clefts treated orthodontically in the Department of Orofacial Orthopedics and Orthodontics at Heim Pàl Children’s Hospital, Budapest. There were 150 patients (84 males, 66 females) with non-syndromic unilateral (UCLP; n=120 patients) or bilateral (BCLP; n=30 patients) cleft formation (lip, alveolus and palate) who met the inclusion criteria. Statistical analysis was performed using the chi-square test and Fisher’s exact test (significance level p<0.05). Results Hypodontia was significantly more frequent in patients with cleft-sided lateral incisor (104 patients, 69%), with a total of 235 missing teeth, followed by the second premolars of the upper and lower jaw. A significant correlation of congenital missing teeth was observed in left-sided clefts between the upper and lower second premolar in the cleft area. Conclusions Hypodontia inside and outside the cleft area was frequently observed. This should affect the therapy plans, especially if the cleft-sided premolar is also absent. Further comprehensive research including numerous random samples is necessary for better estimating other possible associations. PMID:27767023

Dental implants have proven to be a reliable modality for the rehabilitation of missing teeth. However, there are limited reports on managing anodontia related to ectodermal dysplasia in the scientific literature. The severely reduced bone quantity due to the congenital absence of multiple natural teeth is the biggest challenge for the surgeon. There are a variety of bone augmentation procedures to establish adequate bone quantity, and the surgical planning should be used on an individual case basis. This is a report of a 19-year-old male patient affected by hypohidrotic ectodermal dysplasia. Oligodontia associated with severe atrophy of jaws was the chief complaint for seeking treatment. Based on clinical and radiographic examinations, 2 bone augmentation procedures were used to obtain sufficient width of alveolus for implant placement by performing an onlay bone graft in the maxilla and vertical distraction osteogenesis in the mandible. The treatment planning was discussed and informed consent was obtained.

Meta-analysis and systematic review of the number of non-syndromic congenitally missing permanent teeth per affected individual and its influencing factors

Summary Background and purpose: Dental aplasia (or hypodontia) is a frequent and challenging anomaly and thus of interest to many dental fields. Although the number of missing teeth (NMT) in each person is a major clinical determinant of treatment need, there is no meta-analysis on this subject. Therefore, we aimed to investigate the relevant literature, including epidemiological studies and research on dental/orthodontic patients. Methods: Among 50 reports, the effects of ethnicities, regions, sample sizes/types, subjects’ minimum ages, journals’ scientific credit, publication year, and gender composition of samples on the number of missing permanent teeth (except the third molars) per person were statistically analysed (α = 0.05, 0.025, 0.01). Limitations: The inclusion of small studies and second-hand information might reduce the reliability. Nevertheless, these strategies increased the meta-sample size and favoured the generalisability. Moreover, data weighting was carried out to account for the effect of study sizes/precisions. Results: The NMT per affected person was 1.675 [95% confidence interval (CI) = 1.621–1.728], 1.987 (95% CI = 1.949–2.024), and 1.893 (95% CI = 1.864–1.923), in randomly selected subjects, dental/orthodontic patients, and both groups combined, respectively. The effects of ethnicities (P > 0.9), continents (P > 0.3), and time (adjusting for the population type, P = 0.7) were not significant. Dental/orthodontic patients exhibited a significantly greater NMT compared to randomly selected subjects (P < 0.012). Larger samples (P = 0.000) and enrolling younger individuals (P = 0.000) might inflate the observed NMT per person. Conclusions: Time, ethnic backgrounds, and continents seem unlikely influencing factors. Subjects younger than 13 years should be excluded. Larger samples should be investigated by more observers.

Missing posterior teeth can decrease masticatory function and cause horizontal mastication deviation, i.e., mastication predominance. Mastication predominance may lead to abnormal tooth attrition and temporomandibular disorders. This study evaluated masticatory performance and mastication predominance in patients with missing posterior teeth to investigate effects of missing posterior teeth on masticatory performance and mastication predominance. Thirty volunteers with normal dentition (control group), 30 patients with unilateral missing posterior teeth (unilateral group), and 23 patients with bilateral missing posterior teeth (bilateral group) participated. Gummy jellies were used to evaluate participants' masticatory performance, and electromyography was used to assess the degree of mastication predominance. Chewing gums, gummy jellies, and peanuts were used as foods of various hardnesses for evaluating mastication predominance. Compared with the control group, masticatory performance did not differ in the unilateral group but was significantly decreased in the bilateral group. With chewing gum and gummy jellies, the degree of mastication predominance was significantly increased in both unilateral and bilateral groups than the control group. With peanuts, the degree of mastication predominance was significantly increased in the unilateral group than the control group. Although masticatory performance was not decreased in the unilateral group, the degree of mastication predominance was increased. Decreased masticatory performance was observed in the bilateral group, and for foods with normal hardness and soft foods, the degree of mastication predominance was increased. These results suggested that mastication predominance should be considered in the recovery of masticatory performance in patients with missing posterior teeth.

The purpose of this study was to investigate the dental and some other aspects of oral health status of young patients with congenital bleeding disorders (CBD) and the impact of these on their quality of life (OHR-QoL) compared with controls. DMFS-dmfs (Decayed, Missed, Filled Tooth surfaces in permanent and primary teeth) scores, Simplified oral hygiene index, occurance of hypoplasia of first permanent molars, Temporomandibular joint dysfunction and occlusion of 46 CBD patients at the age range of 2-15 years and 46 of other children as control were compared, and the impact of their oral health situation on quality of life was also investigated. Data were analysed by chi-square, t-test and Pearson correlation. Patients were significantly more caries-free with less decayed teeth in primary-permanent dentition (P = 0.03, t = -2.17).The mean scores of OHR-QoL of CBD patients and controls were not significantly different. Oral Bleeding was the significant variable in relation to 'oral health-related quality of life' in CBD groups (Pearson correlation, r = -0.56, P = 0.000). OHR-QoL in the control group was related to dmfs score (r = -0.392, P = 0.011) and male gender (r = -0.329, P = 0.026). Congenital bleeding disorder CBD patients were found to have a better dental health situation in primary dentition compared with controls; however, their 'oral health-related quality of life' was similar. Oral bleeding was the only significant factor related to OHR-QoL in CBD. It shows an overall importance of development of comprehensive care centres for CBD as the main cause of this achievement. © 2012 Blackwell Publishing Ltd.

Our objective was to assess awareness, attitudes, need and demand on replacement of missing teeth according to edentulous space, age, gender, ethnicity, educational level and socio-economical status of the patient. 76.2% of the study group was opined that the missing teeth should be replaced by prosthetic means. Majority were keen in getting them replaced mainly for the comfort in mastication. Although 77.9 and 32.9% were aware of the removable prostheses and implants respectively, only 25.2% knew about tooth supported bridges as an option of replacement of missing teeth. Participants' awareness on tooth and implant supported prostheses is at a higher level. Participants' opinion on need of regular dental visit was statistically significant when gender, ethnicity and education level were considered. The highest demand for replacement of missing teeth was observed in Kennedy class I and II situations in both upper and lower arches. Demand for fixed prostheses was significantly highest in Kennedy class II in upper and lower arches. In conclusion, although removable prosthodontic options are known to most of the patients, their awareness on tooth and implant supported prostheses is also at a higher level. The highest demand for replacement of missing teeth is by patients with Kennedy class I and II situations whereas Kennedy class II being the category with highest demand for fixed prostheses. We recommend that the location of missing teeth to be considered as a priority when educating patients on the most appropriate prosthetic treatment options. Dentists' involvement in educating patients on prosthetic options needs to be improved.

Teeth maintain the functionality and esthetic of oral cavity, they are also important for psychological and social well-being. This study aims to assess awareness of patients toward replacement of missing teeth. People with unrestored or missing teeth tend to have poor self-esteem and oral health-related quality of life; hence, their knowledge toward restoring and replacing teeth is an important aspect to be measured. It was an observational study having a cross-sectional design. Face- and content-validated questionnaire was used as study tool. Nonprobability, convenient sampling technique was employed that yielded information from 183 respondents residing in various areas of Hail city. Data were collected after written informed consent. The study was approved by the University of Hail ethical committee. Two hundred questionnaires were distributed, out of which 183 were returned. Regarding knowledge of restoring missing teeth, 145 (79.2%) respondents know that function and esthetic can be maintained by replacing missing teeth. Information about the availability of various types of prosthesis was mostly obtained by them through their dentist (70; 48.3%), while books/magazines/Internet was the second source (38; 26.2%) and 37 (25.5%) heard it from someone who has already undergone the replacement of teeth. The present study indicated that a good number of respondents have the knowledge of teeth replacement, and dentists were the most common source of information to the patients in terms of education about different treatment options. Evaluate and plan treatment options based on patients' expectations and perceptions.

Osteogenesis imperfecta (OI) is a heterogeneous group of disorders of connective tissue, mainly caused by mutations in the collagen type I genes (COL1A1 and COL1A2). Tooth agenesis is a common feature of OI. We investigated the association between tooth agenesis and collagen type I mutations in individuals with OI. In this cohort study, 128 unrelated individuals with OI were included. Panoramic radiographs were analyzed regarding dentinogenesis imperfecta (DGI) and congenitally missing teeth. The collagen I genes were sequenced in all individuals, and in 25, multiplex ligation-dependent probe amplification was performed. Mutations in the COL1A1 and COL1A2 genes were found in 104 of 128 individuals. Tooth agenesis was diagnosed in 17% (hypodontia 11%, oligodontia 6%) and was more frequent in those with DGI (P = 0.016), and in those with OI type III, 47%, compared to those with OI types I, 12% (P = 0.003), and IV, 13% (P = 0.017). Seventy-five percent of the individuals with oligodontia (≥6 missing teeth) had qualitative mutations, but there was no association with OI type, gender, or presence of DGI. The prevalence of tooth agenesis is high (17%) in individuals with OI, and OI caused by a qualitative collagen I mutation is associated with oligodontia. © 2016 John Wiley & Sons A/S.

The present study aimed to evaluate the effect of implant prostheses on the occlusal force and area as well as the distribution of occlusal loading in unilateral free-end and intermediate missing cases. Fourteen healthy subjects (7 free-end missing cases in the first and second molars and 7 intermediate missing cases in the first molar region) were included. Six months after the implant prosthesis was placed, an occlusal evaluation was performed with or without the implant superstructure by using Dental Prescale film and an occluder device. In free-end missing cases, the total occlusal force and area, implant-side occlusal force and area, and implant-side occlusal force and area of the residual natural teeth were significantly affected by the implant prostheses. In intermediate missing cases, the implant-side occlusal force of the residual natural teeth was significantly affected by the implant prostheses. In free-end missing cases, the proportions of implant-side occlusal force, non-implant-side occlusal force, and implant-side occlusal force of the residual natural teeth relative to the total occlusal force were significantly affected by the implant prostheses. In the intermediate missing cases, the proportion of the implant-side occlusal force of the residual natural teeth relative to the total occlusal force was significantly affected by the implant prostheses. The proportion of the occlusal area was also significantly affected. In free-end missing cases, implant prostheses significantly increased the occlusal force and area, which resulted in the proper occlusal distribution. In intermediate missing cases, an implant prosthesis may only improve the same-side occlusal loading of the natural teeth.

Long-term oral chronic inflammatory process is closely related to systemic inflammation, which is a main mechanism involved in non-alcoholic fatty liver disease (NAFLD). Tooth loss could reflect the accumulation of oral local inflammation, implying that number of missing teeth may associate with NAFLD. This study evaluated the association between missing teeth and presence of NAFLD in a general population. A cross-sectional study of 24,470 adults was carried out from the Tianjin Chronic Low-grade Systemic Inflammation and Health Cohort Study. The self-reported number of missing teeth (excluding third molars) was recorded and classified into four categories: 0, 1-2, 3-5, and ≥6. The NAFLD was diagnosed by the liver ultrasonography. Associations were analyzed by adjusted multivariable logistic regression. The multivariable-adjusted odds ratios (95% confidence interval) of NAFLD across the categories of missing teeth were as follows: in males, 1.00(reference), 1.04(0.93-1.16), 1.06(0.90-1.24), and 1.40(1.09-1.81) (P for trend=0.04); in females, 1.00(reference), 0.98(0.83-1.15), 1.11(0.90-1.37), and 1.07(0.77-1.48) (P for trend=0.45). The number of missing teeth was associated with a higher presence of NAFLD in males but not females. This article is protected by copyright. All rights reserved.

The Hallermann-Streiff Syndrome has been characterized and established according to 7 positive and 5 negative signs, which were described by François. We encountered an 11 year, 5 months old boy who had 7 positive symptoms of this syndrome in our clinic. In this study, we reported on this typical patient focusing on his dental view. 1) Prolonged retention of the primary teeth which involved microdontia were noted. Congenitally missing teeth were also seen. 2) The occlusal relationship indicated open bite, and also the mandibular function was impaired. 3) The measurements of the length and width of the dental arch were smaller than that of a normal subject, and the dental arch of the maxilla was V-shaped. 4) According to X-ray cephalometric analysis, (a) the dental calculus and the alveolar bone absorption were very evident. (b) abnormal morphologic of the glenoid fossa, mandibulars condyle and the neck of mandibula were seen. These conditions were very evident on the left side. 5) The growth obstade of the maxilla and mandibla and the left shift of the mandible were found. 6) According to histological study, enamel hypoplasia was noted.

This study focuses on the dental abnormalities observed by Sir Jonathan Hutchinson, Henry Moon and Alfred Fournier in patients with congenital syphilis and in those treated with mercury, in order to define alterations in dental morphology attributable to each of these causes. These definitions are applied to reported paleopathological cases, exploring various etiologies behind the defects, in order to aid in the diagnosis of congenital syphilis. Original works were examined for descriptions of dental abnormalities in congenital syphilis and in mercurial treatments. These descriptions were compared with dentitions of paleopathological cases (n = 4) demonstrating abnormalities attributed to congenital syphilis. Distinct morphological differences were recognized between congenital syphilitic teeth and teeth affected by mercury. Mercury produces a pronounced deficiency in enamel of incisors, canines and first permanent molars that become rugged and pitted, and of dirty grey honeycombed appearance. Mercury-induced dental changes are evident in three out of four cases studied here. In one case, only syphilitic changes were present. Dental changes in congenital syphilis range from no visible signs to those beyond the classical models of Hutchinson, Moon and Fournier. Treatment of neonates and infants with mercury produces additional changes. Signs of disease and treatment with mercury on teeth may occur together; permanent incisors, first molars and canines, are typically affected, premolars and second/third molars are usually spared. Signs of treatment with mercury might be the only evidence of the occurrence of the disease as mercury was rarely used to treat other diseases. © 2015 Wiley Periodicals, Inc.

The third molar teeth (wisdom teeth) represent the last eruption of the teeth in the human dentition. Throughout evolution, the mandible has had a tendency to decrease in size; the third molar teeth are often impacted, resulting in incomplete tooth eruption that often causes clinical pericoronitis, dental caries, and pericemental abscess. Therefore, the wisdom teeth are often extracted. Moreover, wisdom teeth are often removed for clinical orthodontic treatment. On the other hand, tooth loss due to periodontal disease, dental caries, trauma, or a variety of genetic disorders continues to affect people's lives. Autologous tissues for dental tissue regeneration that could replace lost teeth could provide a vital alternative to currently available clinical treatments. To pursue this goal, we hypothesize that human third molar tooth buds can be obtained during development. Human wisdom tooth germination tissue could then be placed into an embryonic stem cell bank for storage. When the donor's other teeth are missing, embryonic stem cell and tissue engineering technologies, will permit the restoration of the missing teeth. Therefore wisdom teeth will be mankind's future third vice-teeth.

The study aimed to assess the value placed on oral health states by measuring the utility of mouths in which teeth had been lost and to explore variations in utility values within and between two contrasting cultures, UK and Iran. One hundred and fifty eight patients, 84 from UK and 74 from Iran, were recruited from clinics at University-based faculties of dentistry. All had experienced tooth loss and had restored or unrestored dental spaces. They were presented with 19 different scenarios of mouths with missing teeth. Fourteen involved the loss of one tooth and five involved shortened dental arches (SDAs) with varying numbers of missing posterior teeth. Each written description was accompanied by a verbal explanation and digital pictures of mouth models. Participants were asked to indicate on a standardized Visual Analogue Scale how they would value the health of their mouth if they had lost the tooth/teeth described and the resulting space was left unrestored. With a utility value of 0.0 representing the worst possible health state for a mouth and 1.0 representing the best, the mouth with the upper central incisor missing attracted the lowest utility value in both samples (UK = 0.16; Iran = 0.06), while the one with a missing upper second molar the highest utility values (0.42, 0.39 respectively). In both countries the utility value increased as the tooth in the scenario moved from the anterior towards the posterior aspect of the mouth. There were significant differences in utility values between UK and Iranian samples for four scenarios all involving the loss of anterior teeth. These differences remained after controlling for gender, age and the state of the dentition. With respect to the SDA scenarios, a mouth with a SDA with only the second molar teeth missing in all quadrants attracted the highest utility values, while a mouth with an extreme SDA with both missing molar and premolar teeth in all quadrants attracted the lowest utility values. The study provided further evidence of the validity of the scaling approach to utility measurement in mouths with missing teeth. Some cross-cultural variations in values were observed but these should be viewed with due caution because the magnitude of the differences was small.

How much of the income inequality effect can be explained by public policy? Evidence from oral health in Brazil.

PubMed

Celeste, Roger Keller; Nadanovsky, Paulo

2010-10-01

To evaluate the association between income inequality, a public policy scale and to oral health. Analysis, using the Brazilian oral health survey in 2002-2003, included 23,573 15-19-year-old subjects clustered in 330 municipalities. Missing and decayed teeth and malocclusion assessments were the outcomes. Gini coefficient and a novel Scale of Municipal Public Policies were the main exposure variables. Individual level covariates were used as controls in multilevel regressions. An increase from the lowest to the highest Gini value in Brazil was associated with an increase in the number of missing (rate ratio, RR=2.11 confidence interval 95% 1.18-3.77) and decayed teeth (RR=2.92 CI 95% 1.83-4.65). After adjustment for public policies and water fluoridation, the Gini effect was non-significant and public policies explained most of the variation in missing and decayed teeth. The public policy scale remained significant after adjustment with a rate ratio of 0.64 for missing and 0.72 for decayed teeth. Neither Gini nor public policies were significantly related to malocclusion. The public policy effect on missing and decayed teeth was stronger among those with higher education and income. Income inequality effect was explained mainly by public policies, which had an independent effect that was greater among the better-off. Copyright (c) 2010 Elsevier Ireland Ltd. All rights reserved.

  Children with autism might need more dental care than non-autistic, healthy children. The aims of this study were: (a) to describe the caries experience and treatment needs of autistic children aged 6-16 years in the United Arab Emirates; and (b) to provide baseline data at national and regional levels to enable comparisons and future planning of dental services for children with autism.   All children attending a day centre in Sharjah, United Arab Emirates, for autism were selected for the study. Sixty-one autistic children aged 6-16 years (45 males and 16 females) were included in the study. Each patient received a complete oral and periodontal examination using codes and criteria as described by the World Health Organization.   The overall mean for Decayed, Missing, and Filled Teeth/decayed, missing, and filled teeth was 2.4. Female autistic children had significantly higher mean Decayed, Missing, and Filled Teeth/decayed, missing, and filled teeth scores (4.4) than males (1.63). The percentage of decayed, missing, and filled teeth increased with increasing age. The restorative index and met need index for the autistic children aged 11-15 years were 0.02 and 0.10, respectively.   Effective oral health promotion strategies need to be implemented to improve the oral health status of autistic children. © 2010 Blackwell Publishing Asia Pty Ltd.

Congenital cardiac magnetic resonance is a limited resource because of scanner and physician availability. Missed appointments decrease scheduling efficiency, have financial implications and represent missed care opportunities. To characterize the rate of missed appointments and identify modifiable predictors. This single-center retrospective study included all patients with outpatient congenital or pediatric cardiac MR appointments from Jan. 1, 2014, through Dec. 31, 2015. We identified missed appointments (no-shows or same-day cancellations) from the electronic medical record. We obtained demographic and clinical factors from the medical record and assessed socioeconomic factors by U.S. Census block data by patient ZIP code. Statistically significant variables (P<0.05) were included into a multivariable analysis. Of 795 outpatients (median age 18.5 years, interquartile range 13.4-27.1 years) referred for congenital cardiac MR, a total of 91 patients (11.4%) missed appointments; 28 (3.5%) missed multiple appointments. Reason for missed appointment could be identified in only 38 patients (42%), but of these, 28 (74%) were preventable or could have been identified prior to the appointment. In multivariable analysis, independent predictors of missed appointments were referral by a non-cardiologist (adjusted odds ratio [AOR] 5.8, P=0.0002), referral for research (AOR 3.6, P=0.01), having public insurance (AOR 2.1, P=0.004), and having scheduled cardiac MR from November to April (AOR 1.8, P=0.01). Demographic factors can identify patients at higher risk for missing appointments. These data may inform initiatives to limit missed appointments, such as targeted education of referring providers and patients. Further data are needed to evaluate the efficacy of potential interventions.

X-linked hypohidrotic ectodermal dysplasia (XLHED) is characterized by abnormalities of hair, teeth, and sweat glands, while non-syndromic hypodontia (NSH) affects only teeth. Mutations in Ectodysplasin A (EDA) underlie both XLHED and NSH. This study investigated the genetic causes of six hypohidrotic ectodermal dysplasia (HED) patients and genotype-phenotype correlation. The EDA gene of six patients with HED was sequenced. Bioinformatics analysis and structural modeling for the mutations were performed. The records of 134 patients with XLHED and EDA-related NSH regarding numbers of missing permanent teeth from this study and 20 articles were reviewed. Nonparametric tests were used to analyze genotype-phenotype correlations. In four of the six patients, we identified a novel mutation c.852T>G (p.Phe284Leu) and three reported mutations: c.467G>A (p.Arg156His), c.776C>A (p.Ala259Glu), and c.871G>A (p.Gly291Arg). They were predicted to be pathogenic by bioinformatics analysis and structural modeling. Genotype-phenotype correlation analysis revealed that truncating mutations were associated with more missing teeth. Missense mutations and the mutations affecting the TNF homology domain were correlated with fewer missing teeth. This study extended the mutation spectrum of XLHED and revealed the relationship between genotype and the number of missing permanent teeth. © 2015 John Wiley & Sons A/S.

The aim of this study was to evaluate the association between crack/cocaine addiction and dental health in men. Forty crack/cocaine-addicted patients and 120 nonaddicted patients (≥18 years) underwent full-mouth dental examinations. Decayed, missing, and filled teeth (DMFT) were identified using the criteria recommended by the World Health Organization. Crack/cocaine addiction was determined, based on the medical records and interviews of each patient. All drug-addicted patients used both crack and cocaine. The chi-square test and logistic regression analysis were used to assess the association between DMFT and crack/cocaine addiction (p ≤ 0.05). Decayed teeth showed a positive association with crack/cocaine addiction (odds ratio (OR) = 3.65; 95% confidence interval (CI), 1.68-7.92; p = 0.001), whereas filled and missing teeth showed a negative association (filled teeth: OR = 0.37; 95% CI, 0.18-0.76; p = 0.008; missing teeth: OR = 0.33; 95% CI, 0.13-0.81; p = 0.02). The DMFT was only associated with age (OR = 2.12; 95% CI, 1.11-4.08, p = 0.023). In the present population, crack/cocaine addiction was associated with a greater decayed teeth index and a lower filled and missing teeth index. Programs aimed to encourage self-esteem and encourage individuals to seek dental care are required for this population. Further studies using a larger sample size and studies with women are required to confirm the results.

We present association results from a large genome-wide association study of tooth agenesis (TA) as well as selective TA, including 1,944 subjects with congenitally missing teeth, excluding third molars, and 338,554 controls, all of European ancestry. We also tested the association of previously identified risk variants, for timing of tooth eruption and orofacial clefts, with TA. We report associations between TA and 9 novel risk variants. Five of these variants associate with selective TA, including a variant conferring risk of orofacial clefts. These results contribute to a deeper understanding of the genetic architecture of tooth development and disease. The few variants previously associated with TA were uncovered through candidate gene studies guided by mouse knockouts. Knowing the etiology and clinical features of TA is important for planning oral rehabilitation that often involves an interdisciplinary approach.

Very few modalities can be used for restoring missing primary anterior teeth, although the impact of missing anterior teeth during early childhood can be harmful. In the permanent dentition the use of glass-fibers ribbon and composite materials are frequently used for restoring missing teeth with no or minimal preparation. The purpose of this study was to examine the possibility to use the glass-fibers ribbon (ever-Stick from GC Corporation, Japan) together with esthetic composite materials (G-aenial A1 from GC Corporation, Japan) for restoring anterior primary teeth and to determine the best methodology and bonding system to be used. The effect of etching time was analyzed using 20-80 sec on primary buccal enamel with SEM and the results showed that at least 60 second is necessary in order to remove the prismless layer and to affect the prismatic layer similar (as observed by SEM) to the 20 sec etching time on permanent enamel. Three bonding systems (SE Bond by Kurary, Japan, Scotchbond Universal by 3M/ESPE, Germany and G-aenial bond by GC Company, Japan) were compared for bonding the glass-fibers ribbon to the primary enamel and microtensile strength analyses were performed. Mean tensile strength ranged from 10.9 to 13 MPa with no statistically significant differences between all three systems. Based on the laboratory results it can be concluded that the glass-fibers ribbon together with the composite material can be used clinically to restore missing primary teeth for esthetic and functional reasons. Two clinical cases are presented that show favorable results. PMID:25553140

The premature loss of primary teeth may reduce arch length required for the succeeding tooth and, hence, predisposes crowding, rotation and impaction of the permanent teeth. There are only limited studies carried out about the prevalence of early loss of primary teeth. The present study was performed to evaluate the prevalence of early loss of primary teeth in school children in Chidambaram town in Tamilnadu, India. A total of 1121 school children (561 boys and 560 girls) between 5 and 10 years of age were selected for the study. An experienced examiner performed all clinical examinations under natural light. Data including age and missing tooth was collected. Microsoft Excel/2000 (Microsoft Office XP) data spreadsheet was used and later exported to the Statistical Package for Social Science (SPSS) for Windows (version 10.0). Descriptive statistics was applied and, from the results, chi-square tests were applied at a level of significance of 5% (P < 0.05). The results showed that 16.5% of the sample had early loss of primary teeth, but no differences were observed between genders (P > 0.05). The greatest prevalence was found among the 8-year olds (5.08%), and the most commonly missing teeth were the right lower primary first molars (16.82%). It can be concluded that the prevalence of early loss was high and that the lower primary molars were the most commonly missing teeth in the present study.

The number of missing teeth in people of the Edo period in Japan in the 17th to 19th centuries.

The aims of this study were to examine the number of missing teeth in the people of the Edo period (or number of remaining teeth) and to contribute to the 8020 movement proposed in Japan to help people retain 20 or more of their own teeth until the age of 80. The study of dentition in ancient skeletal remains of our ancestors from multiple perspectives can yield information that can contribute to the study of physical anthropology and the leading edge of modern dental research. The materials were 82 excavated individuals (52 males and 30 females) from 1603 to 1868 whose maxillas and mandibles were both examinable. The age and sex were estimated by anthropological methods, and the individuals were divided into five groups. The status of missing teeth was compared between groups, and a chi-square test was used to test significant differences between groups. The rates of tooth loss were examined in the maxillas and mandibles. In the people of the Edo period, many teeth remained in good condition until early to late middle age. There were more remaining teeth in these individuals than in modern-day individuals. However, the Edo people clearly showed increased tooth loss with age. There were no differences in tooth loss by sex. The tooth type with a high rate of tooth loss was posterior teeth, but incisor loss also occurred with ageing. Mandibular canines were most likely to be remaining. The Edo people had more remaining teeth than modern-day society. This finding was unexpected. The notion that "people of long past ages lost more teeth more quickly" does not seem to apply to people in the Edo period in Japan. © 2011 The Gerodontology Society and John Wiley & Sons A/S.

Syndromes with salivary dysfunction predispose to tooth wear: Case reports of congenital dysfunction of major salivary glands, Prader-Willi, congenital rubella, and Sjögren's syndromes.

2001-07-01

Four cases-of congenital dysfunction of the major salivary glands as well as of Prader-Willi, congenital rubella, and Sjögren's syndromes-were identified in a series of 500 patients referred for excessive tooth wear. Although there was evidence of consumption of highly acidic drinks, some occlusal parafunction, and unacceptable toothbrushing habits, salivary dysfunction was the salient factor predisposing a patient to tooth wear in these syndromal cases. The 500 subjects have been characterized either as having medical conditions and medications that predispose them to xerostomia or lifestyles in which workplace- and sports-related dehydration lead to reduced salivary flow. Normal salivation, by buffering capacity, clearance by swallowing, pellicle formation, and capacity for remineralization of demineralized enamel, protects the teeth from extrinsic and intrinsic acids that initiate dental erosion. Thus, the syndromes, unrelated in many respects, underline the importance of normal salivation in the protection of teeth against tooth wear by erosion, attrition, and abrasion.

A 49-year-old woman with several missing and periodontically compromised teeth was referred to the orthodontic department of National Health Insurance Service Ilsan Hospital by the periodontic department for interdisciplinary treatment. Multiple posterior teeth had been extracted 10 days earlier. Her chief complaint was crowding of the anterior teeth, and she wanted to improve both esthetics and function. Orthodontic, periodontic, and prosthodontic treatments were undertaken in the proper timing and sequence with an interdisciplinary approach. As a result, improved periodontal health and a stable occlusion and vertical dimension were achieved. Although there were limited teeth and alveolar bone for anchorage, good esthetic and functional treatment results were obtained through the application of temporary anchorage devices and proper biomechanics.

Chen, Amy Yi-Ling; Chen, Kevin

2017-01-01

Incontinentia pigmenti (IP) is a uncommon gene disorder, heritage with X-linked dominant mode. IP patients have a characteristic dentition varying from marked hypodontia to delayed eruption and conical crowns on both dentitions. A 5½-year-old girl, whose mother and younger sister were also diagnosed with IP, has the whirling-like pigmented skin lesion over her trunk and four extremities. Four primary teeth and multiple permanent tooth germs were found to be congenital missing. Dental considerations of further treatment were discussed with her parents including the preservation of primary molars, possible interim prosthesis in mixed or permanent dentition, full mouth rehabilitation with orthodontic and prosthodontic combined treatment, and implant therapy in adulthood. Early and longitudinal involvement of pediatric dentist to deal with the dental complications of IP can not only solve the esthetic problem and oral function but also maintain the oral health of children with IP to adulthood.

To describe health care providers' missed opportunities for preventing and treating congenital syphilis in New York City. Review of congenital syphilis cases reported to the New York City Department of Health and Mental Hygiene from January 1, 2000 to December 31, 2009. Receipt and timing of prenatal care, serologic testing, and treatment of mothers and newborns were reviewed. Missed opportunities were defined as receipt of prenatal care plus one of the following: 1) lack of documented treatment for syphilis infection diagnosed before pregnancy; 2) absence of serologic testing during pregnancy; 3) late maternal treatment; 4) maternal treatment with a nonpenicillin regimen; or 5) lack of maternal treatment. In total, 195 newborns with congenital syphilis were born to 190 mothers with 191 pregnancies. Overall, 80% (95% confidence interval [CI] 74-86%, 152 of 190) of all mothers received prenatal care; 63% (95% CI 56-71%, 96 of 152) of these had one or more missed opportunities for prevention. Twelve mothers received inadequate treatment or no treatment during the case pregnancy for documented syphilis infection before pregnancy, and 42 mothers without previous syphilis diagnosis did not have serologic testing during the case pregnancy. Of 103 mothers with syphilis diagnosed before 30 weeks of gestation, 12 received late penicillin therapy, 27 received no therapy, and 3 received inappropriate (nonpenicillin) therapy. Seventeen percent (95% CI 12-22%, 33 of 193) of liveborn newborns received no treatment during their hospitalization. Providers missed well-defined opportunities to prevent congenital syphilis for the majority of cases. Combined efforts to prevent future cases include provider education and better integration of care between obstetricians and pediatricians. III.

Oral health problems are significant cause of morbidity particularly in sub-Saharan Africa. In Malawi, routine health management information system data over the years showed that oral health problems were one of the top ten reasons for outpatient attendance. However, to date, no national oral survey has been carried out to determine the prevalence of oral health problems. A national population-based cross-sectional survey was conducted in 2013. A total of 130 enumeration areas (EAs) were randomly selected and from each EA, 40 participants were randomly selected as per WHO STEPS survey protocol. Eligible participants were 12, 15, 35-44 and 65-74 year old. A multi-stage sampling design was used to obtain a national representative sample of these age groups. Oral examination was based on WHO diagnostic criteria (2010). A total of 5400 participants were enrolled in the survey. Of these: 3304 (61.3 %) were females, 2090 (38.7 %) were males; 327 (6.9 %) were from urban and 4386 (93.1 %) from rural areas; 1115 (20.6 %), 993 (17.3 %), 2306 (42.7 %) and 683 (12.6 %) were aged 12, 15, 35-44, 65-74 years respectively. Among 12 year-old, 15 year-old, 35-44 and 65-74 year age groups, prevalence of dental caries was 19.1, 21.9, 49.0 and 49.2 % respectively, overall 37.4 %. Prevalence of missing teeth was 2.7, 5.2, 47.7 and 79.9 %, overall 35.2 %. Prevalence of filled teeth was 0.2 %, 1.3 %, 8.7 %, 12.7 %, overall 6.5 %. Prevalence of bleeding gums was 13.0, 11.8, 30.8 and 36.1 %, overall 23.5 %. Toothache, dental caries and missing teeth were more common in females than males; 46.5 % vs 37.9 %, 40.5 % vs 32.4 %, 37.7 % vs 30.1 % respectively, all p < 0.05. Prevalence of dental caries and missing teeth in urban areas were as high as in the rural areas; 33.3 % vs 37.4 % and 30.9 % vs 33.7 % respectively, all p > 0.05. The mean number of decayed, missing and filled teeth (DMFT) in 12, 15, 35-44, 65-74 year old was 0.67, 0.71, 3.11 and 6.87 respectively. Self- reported brushing of teeth was poor with only 35.2 % of people brushed their teeth twice a day and tobacco smoking was high, particularly among adult males where one in five (22.9 %) was a smoker. This study demonstrated that oral health problems are major public health problems in Malawi. One in five (21 %) adolescents aged 12-15 years and half (49 %) of adults aged 35 years or more had dental caries, half (48 %) and 80 % of the population aged 35-44, 65-74 years had missing teeth respectively. Toothache, dental caries and missing teeth were more prevalent in females than males and prevalence in urban was as high as in rural areas. Oral hygiene was poor with less than 40 % of the population brush their teeth twice a day and tobacco smoking was high, particularly in men where prevalence was 23 %. These findings could be used to develop evidence-informed national policy, action and resource mobilization plan and community based interventions to reduce the prevalence of oral health problems in Malawi.

The objective of the study was to determine the effect of dental health status, dental anxiety and oral-health-related quality of life (OHRQoL) upon homeless people's experience of depression. A cross-sectional survey was conducted on a sample of homeless people in seven National Health Service Boards in Scotland. All participants completed a questionnaire to assess their depression, dental anxiety and OHRQoL using reliable and valid measures. Participants had an oral examination to assess their experience of tooth decay (decayed and missing teeth). Latent variable path analysis was conducted to determine the effects of dental health status on depression via dental anxiety and OHRQoL using intensive resampling methods. A total of 853 homeless people participated, of which 70% yielded complete data sets. Three latent variables, decayed and missing teeth, dental anxiety (Modified Dental Anxiety Scale: five items) and depression (Center for Epidemiological Studies Depression Scale: two factors), and a single variable for OHRQoL (Oral Health Impact Profile total scale) were used in a hybrid structural equation model. The variable decayed and missing teeth was associated with depression through indirect pathways (total standardised indirect effects=0.44, P<.001), via OHRQoL and dental anxiety (χ²=75.90, df=40, comparative fit index=0.985, Tucker-Lewis index=0.977, root mean square error of approximation=0.051 [90% confidence interval: 0.037-0.065]). Depression in Scottish homeless people is related to dental health status and oral-health-related factors. Decayed and missing teeth may influence depression primarily through the psychological constructs of OHRQoL and, to a lesser extent, dental anxiety. Copyright © 2010 Elsevier Inc.

ABSTRACT Few studies have focused on the bacterial species associated with the deterioration of the dental and gingival health of children with congenital heart defects (CHD). The aims of this study were (1) to examine the dental plaque of children with CHD in order to quantify bacterial load and altered bacterial composition compared with children without CHD; and (2) to investigate the correlation between the level of caries and gingivitis and dental biofilm bacteria among those children. In this cross-sectional study, participants were children (3–12 years) recruited in Khartoum State, Sudan. A total of 80 CHD cases from the Ahmed Gasim Cardiac Centre and 80 healthy controls from randomly selected schools and kindergartens were included. Participants underwent clinical oral examinations for caries (decayed, missing, and filled teeth indices [DMFT] for primary dentition, and DMFT for permanent dentition), and gingivitis (simplified gingival index [GI]). Pooled dental biofilm samples were obtained from four posterior teeth using paper points. Real-time quantitative polymerase chain reaction was used for the detection and quantification of Streptococcus mutans, Streptococcussanguinis, and Lactobacillus acidophilus. Checkerboard DNA–DNA hybridization was used for the detection of 40 additional bacterial species. CHD cases had a significantly higher caries experience (DMFT = 4.1 vs. 2.3, p < 0.05; DMFT = 1.4 vs. 0.7, p < 0.05) and a higher mean number of examined teeth with gingivitis (4.2 vs. 2.0; p < 0.05) compared with controls. S. mutans counts were significantly higher among the CHD cases (p < 0.05). Checkerboard results revealed that 18/40 bacterial species exhibited significantly higher mean counts among CHD cases (p < 0.01). Correlation analyses revealed that among CHD cases, the detection levels of Tannerella forsythia, Campylobacter rectus, Fusobacterium nucleatum subsp. vincentii, F. nucleatum subsp. nucleatum, and F. nucleatum subsp. polymorphum were highly positively correlated with GI. CHD cases harbor more cariogenic and periodontopathogenic bacterial species in their dental plaque, which correlated with higher levels of caries and gingivitis. PMID:28326155

Late congenital syphilis is a very rare clinical entity, and its early diagnosis and treatment is essential. Dental findings often provide valuable evidence for the diagnosis of late congenital syphilis. It occurs due to the transmission of the disease from an infected mother to her fetus through placenta. This long forgotten disease continues to effect pregnant women resulting in perinatal morbidity and mortality. Congenital syphilis is a preventable disease, and its presence reflects a failure of prenatal care delivery system, as well as syphilis control programs. We are reporting a case of late congenital syphilis with only Hutchinson's teeth.

Objective: The aims of this study were to determine the prevalence of hypodontia in the permanent dentition in a sample of Sudanese patients who sought orthodontic treatment and to compare the results with the reported findings of other populations. Materials and Methods: Orthodontic files including orthopantomographs of 1069 patients (760 females and 309 males - more than 8 years old) were examined and inspected for evidence of hypodontia. Results: The prevalence of hypodontia of the present sample was 5.1%. Hypodontia was found considerably more frequently in the mandible than in the maxilla. The distribution of missing teeth was noticed in the left side more than in the right side. The most frequently missing teeth were the maxillary lateral incisors, followed by the mandibular second premolars, maxillary second premolars and mandibular left lateral incisor. The majority of patients had two or three teeth missing, but rarely more than 5 teeth missing. Conclusions: The prevalence of hypodontia of this study was within the range of that reported in the literature. The incidence of hypodontia in the anterior segment requires great need for orthodontic and prosthodontic treatment. With early detection of hypodontia, alternative treatment modalities can be planned and performed with a multidisciplinary team approach restoring the esthetic and function. PMID:25143929

Maxillary lateral incisor agenesis (MLIA) is a condition that affects both dental esthetics and function in young patients, and represents an important challenge for clinicians. Although several treatment options are available, the mesial repositioning of the canines followed by teeth recontouring into lateral incisors; or space opening/maintenance followed by implant placement have recently emerged as two important treatment approaches. In this article, the current and latest literature has been reviewed in order to summarize the functional and esthetic outcomes obtained with these two forms of treatment of MLIA patients in recent years. Indications, clinical limitations and the most important parameters to achieve the best possible results with each treatment modality are also discussed. Within the limitations of this review, it is not possible to assert at this point in time that one treatment approach is more advantageous than the other. Long-term followup studies comparing the existing treatment options are still lacking in the literature, and they are necessary to shed some light on the issue. It is possible, however, to state that adequate multidisciplinary diagnosis and planning are imperative to define the treatment option that will provide the best individual results for patients with MLIA.

No meta-analyses or systematic reviews have been conducted to evaluate numerous potential biasing factors contributing to the controversial results on congenitally missing teeth (CMT). We aimed to perform a rather comprehensive meta-analysis and systematic review on this subject. A thorough search was performed during September 2012 until April 2013 to find the available literature regarding CMT prevalence. Besides qualitatively discussing the literature, the meta-sample homogeneity, publication bias, and the effects of sample type, sample size, minimum and maximum ages of included subjects, gender imbalances, and scientific credit of the publishing journals on the reported CMT prevalence were statistically analyzed using Q-test, Egger regression, Spearman coefficient, Kruskal-Wallis, Welch t test (α=0.05), and Mann-Whitney U test (α=0.016, α=0.007). A total of 111 reports were collected. Metadata were heterogeneous (P=0.000). There was not a significant publication bias (Egger Regression P=0.073). Prevalence rates differed in different types of populations (Kruskal-Wallis P=0.001). Studies on orthodontic patients might report slightly (about 1%) higher prevalence (P=0.009, corrected α=0.016). Non-orthodontic dental patients showed a significant 2% decline [P=0.007 (Mann-Whitney U)]. Enrolling more males in researches might significantly reduce the observed prevalence (Spearman ρ=-0.407, P=0.001). Studies with higher minimums of subjects' age showed always slightly less CMT prevalence. This reached about -1.6% around the ages 10 to 13 and was significant for ages 10 to 12 (Welch t test P<0.05). There seems to be no limit over the maximum age (Welch t test P>0.2). Studies' sample sizes were correlated negatively with CMT prevalence (ρ=-0.250, P=0.009). It was not verified whether higher CMT rates have better chances of being published (ρ=0.132, P=0.177). CMT definition should be unified. Samples should be sex-balanced. Enrolling both orthodontic and dental patients in similar proportions might be preferable over sampling from each of those groups. Sampling from children over 12 years seems advantageous. Two or more observers should examine larger samples to reduce the false negative error tied with such samples.

It has been well documented that dental caries affect millions of children in the USA with the majority experiencing decay by the late teens. This is especially true for low-income minorities. The objective of this descriptive study was to determine dental caries prevalence in a sample of low-income African-American youth and adults. A total of 1034 individuals were examined. They were divided into two age groups: youth, 9-19 years and adults, 20-39 years. Females comprised approximately 65 percent (64.5) of the study group. The DMFT Index was used to determine caries prevalence in this study population. The DMFT findings showed that approximately 73 percent (72.9 percent) of the youth had either decayed, missing or filled teeth. Male youth had slightly higher DMFT mean scores than female youth: male mean = 7.93, standard error = 0.77, female mean = 7.52, standard error = 0.36; however, as females reached adulthood their DMFT scores increased substantially, mean = 15.18, standard error = 0.36. Caries prevalence was much lower in male adults, DMFT, mean = 7.22, standard error of 0.33. The decayed component for female adults mean score was 6.81, a slight increase over adult males, mean = 6.58. Although there were few filled teeth in both age groups, female adults had slightly more filled teeth than male adults, females mean = 2.91 vs. males; however, adult males experienced slightly more missing teeth, mean = 5.62 as compared to adult females, mean = 5.46. n = 2.20. Both female and male adults had an increase in missing teeth. As age increased there was a significant correlation among decayed, missing and filled teeth as tested by Analysis of Variance (ANOVA), p < 0.01. A significant correlation was found between filled teeth by sex, p < .005. We conclude that caries prevalence was higher in female and male youth, but dental caries increased more rapidly in females as they reached adulthood.

To compare the associations between socioeconomic factors and tooth loss among White, Black, and Mexican-American people. Analyses were conducted on 16,821 adults, using data from the National Health and Nutrition Examination Survey-III. Age- and multivariate-adjusted negative binomial regressions were used to explore the relation of socioeconomic factors, region of residence, gender, and foreign birth with the number of missing teeth. Effect modification by race/ethnicity was assessed by the inclusion of interaction terms. In multivariate-adjusted analyses, non-Hispanic White people with 9-12 years of education exhibited 71% higher mean number of missing teeth than those with >12 years of education [incidence rate ratio (IRR) = 1.71, 95% confidence interval (CI): 1.52-1.92]. Education was unrelated to the number of teeth among non-Hispanic Black people (IRR = 1.16; 95% CI: 1.00-1.35) or Mexican-Americans (IRR = 1.10, 95% CI: 0.93-1.31). The poorest White people exhibited 39% more missing teeth, on average, than the most affluent White people, but no association between poverty and number of teeth was observed among Black or Mexican-American people. The associations between socioeconomic factors and tooth loss vary across race/ethnicity. This suggests that the health benefits associated with high socioeconomic status are not equally shared across racial/ethnic groups.

Despite the reported occurrence of dental anomalies of cleft lip and palate, little is known about their prevalence in children from Northern Finland with cleft lip and palate. The aim was to investigate the prevalence of dental anomalies among patients with different types of clefts in Northern Finland. Design and Statistics: patient records of 139 subjects aged three years and older (with clefts treated in Oulu University Hospital, Finland during the period 1996-2010 (total n. 183) were analysed for dental anomalies including the number of teeth, morphological and developmental anomalies and their association with the cleft type. The analyses were carried out using Chi-square test and Fisher's exact test. Differences between the groups were considered statistically significant at p values < 0.05. More than half of the patients had clefts of the hard palate, 18% of the lip and palate, and 13% of the lip. At least one dental anomaly was detected in 47% of the study population. Almost one in three (26.6%) subjects had at least one anomaly and 17.9% had two or three anomalies. The most common type of anomaly in permanent teeth were missing teeth followed by supernumerary teeth. Supernumerary teeth were significantly more apparent when the lip was involved in the cleft compared with palatal clefts. Missing teeth were less prevalent among those 5 years or younger. The prevalence of different anomalies was significantly associated with the cleft type in both age groups. Dental anomalies are more prevalent among cleft children than in the general population in Finland. The most prevalent anomalies associated with cleft were missing and supernumerary teeth.

A 6-mo-old, male African hedgehog (Atelerix albiventris) presented with a history of pink urine and demonstrating pink-colored teeth and mild hepatomegaly on examination. Urinalysis revealed no physical, chemical, or cellular abnormalities other than a pink color and fluorescence under ultraviolet light (UV). Also under UV, intense fluorescence of teeth, feet, and spines was noted. Porphyria was suspected. Spectrophotometric evaluation of urine showed extremely elevated levels of copro- and uroporphyrins. Analysis of the urine by thin-layer chromatography showed an abnormal pattern of excreted porphyrin intermediates. Urine high-performance thin-layer chromatography showed that excreted porphyrins were 90-95% of the type-I isomeric form, suggestive of congenital erythropoietic porphyria.

En-masse protraction of mandibular posterior teeth into missing mandibular lateral incisor spaces using a fixed functional appliance.

PubMed

Chhibber, Aditya; Upadhyay, Madhur

2016-11-01

Protraction of mandibular posterior teeth requiring absolute anchorage has always been a challenge, especially when the space is located in the anterior region, since more teeth must be protracted. Traditionally, skeletal anchorage devices have been used for anchorage reinforcement during protraction. However, drawbacks such as requirement of a surgical step, inability to tolerate heavy forces, and patient willingness to undergo such surgical procedures can be limiting factors. Additionally, the mechanics involved can sometimes create undesirable side effects, thereby limiting their application in such situations. This report describes the use of a fixed functional appliance as an anchorage-reinforcement device for en-masse protraction of mandibular posterior teeth into a missing lateral incisor space.

2012-01-01

A study was conducted to determine the degree of tooth loss, factors influencing tooth loss, and the extent of prosthodontic rehabilitation in Sudanese adults (≥ 16 years old) attending outpatient clinics in Khartoum State. Pearson and multivariate analyses were used to examine the relationships between tooth loss and specific characteristics determined through interviews and clinical examinations. The mean number of missing teeth was 3.6 (SD, 4.9) and the prevalence of edentulism was 0.1%. The prevalence of tooth loss (missing at least one tooth) was 78%; 66.9% of tooth loss was due to caries, and 11.2% was attributable to other reasons. Prosthetic replacement of missing teeth was evident in 3%, whereas a need for prosthetic replacement was evident in 57%. Having < 20 teeth was associated with age, gender, and socioeconomic status; tooth loss due to caries was associated with age, tribe, frequency of tooth-brushing, and a low rate of dental consultation. Tooth loss due to other reasons was associated with age, tribe, education, periodontal pocketing, tobacco use, tooth wear, and prosthetic status. The results of the present study indicated that the major cause of tooth loss was dental caries, thus emphasizing the importance of a public prevention-based healthcare program. Replacement of missing teeth was uncommon in the study subjects, which may reflect lack of access to this type of oral healthcare.

Background NF1 is a relatively frequently occurring autosomal dominant inherited disease. There are conflicting reports about oral health status in NF1. The aim of this study was to analyze the dental status of patients with neurofibromatosis type 1 (NF1). Material and Methods Radiographs of 179 patients with NF1 were analyzed for decayed, missing, and filled teeth (DMFT) in a cross-sectional, retrospective study. The results were compared to age- and sex-matched controls of individuals not affected by NF1. The NF1 group was differentiated for facial tumor type and localization. Results Missing teeth were more frequently registered in the NF1 group. On the other hand, decayed teeth were more frequent in the reference group. However, these findings had to be interpreted with caution, because the type and localization of the facial tumor affected the measured values. Conclusions Dental health in terms of DMFT differed between NF1 patients and the control group. The presented results indicate the need for special care in dentistry in NF1 patients in order to preserve dental health, particularly in individuals affected with certain types of facial tumors. Key words:DMFT index, neurofibromatosis type 1, plexiform neurofibroma, oral health. PMID:29670726

Regional early development and eruption of permanent teeth: case report.

Al Mullahi, A M; Bakathir, A; Al Jahdhami, S

2017-02-01

Early development and eruption of permanent teeth are rarely reported in scientific literature. Early eruption of permanent teeth has been reported to occur due to local factors such as trauma or dental abscesses in primary teeth, and in systemic conditions. Congenital diffuse infiltrating facial lipomatosis (CDIFL) is a rare condition that belongs to a group of lipomatosis tumours. In this disorder, the mature adipocytes invade adjacent soft and hard tissues in the facial region. Accelerated tooth eruption is one of the dental anomalies associated with CDIFL. A 3-year-old boy presented with a swelling of the lower lip localised early development and eruption of permanent teeth and dental caries involving many primary teeth. The planned treatment included biopsy of the swollen lower lip to confirm the diagnosis, surgical reduction and reconstruction of lip aesthetics. The management of the carious primary teeth included preventative and comprehensive dental care and extractions. These procedures were completed under general anaesthesia due to the child's young age and poor cooperation. The lip biopsy showed features of CDIFL such as the presence of infiltrating adipose tissue, prominent number of nerve bundles and thickened vessels. The high recurrence rate of CDIFL mandates long-term monitoring during the facial growth period of the child. Follow-up care by the paediatric dentist and maxillofacial surgeon has been required to manage all aspects of this congenital malformation. This rare disorder has many implications affecting child's facial aesthetics, psychological well being, developing occlusion and risk of dental caries. A multi-disciplinary approach is needed for management of this condition.

A high number of patients have one or more missing tooth and it is estimated that one in four American subjects over the age of 74 have lost all their natural teeth. Many options exist to replace missing teeth but dental implants have become one of the most used biomaterial to replace one (or more) missing tooth over the last decades. Contemporary dental implants made with titanium have been proven safe and effective in large series of patients. This review considers the main historical facts concerned with dental implants and present the different critical factors that will ensure a good osseo-integration that will ensure a stable prosthesis anchorage.

Objectives: To determine the prevalence of dental caries in the primary and permanent teeth, and evaluate the brushing habits of school children in Dammam, Kingdom of Saudi Arabia (KSA). Methods: This study was conducted at Dammam, KSA. Oral examination of the participants was conducted from February to May 2014. The total sample size for this cross-sectional study was 711. There were 397 children between the age of 6-9 years, who were examined for primary teeth caries, and 314 between the age 10-12 years were examined for permanent teeth caries. Primary and permanent dentitions were studied for decayed, missing, and filled teeth (dmft [primary teeth], DMFT [permanent teeth]). Results: The overall prevalence of dental caries in primary and permanent teeth was almost 73% (n=711). Among the 6-9-year-old, the prevalence of caries was approximately 78% (n=397) whereas, among the 10-12-year-old children, it was approximately 68% (n=314). Mean dmft value among the 6-9-year-olds was 3.66±3.13 with decayed (d) component of 3.28±2.92, missing (m) component of 0.11±0.69, and filled (f) component of 0.26±0.9. Mean DMFT value among the 10-12-year-old children was 1.94±2.0 with decayed (D) component of 1.76±1.85, missing (M) component of 0.03±0.22, and filled (F) of component 0.15±0.73. Daily tooth brushing had a positive effect on caries prevention, and this effect was statistically significant for caries in primary teeth. Conclusion: Although the prevalence of dental caries in primary and permanent teeth was not found to be as high as other researchers reported from different cities of KSA, still the prevalence was high considering the World Health Organization future oral health goals. Awareness should be provided to students, as well as, teachers and parents regarding the importance of good brushing habits and regular dental visits. PMID:25987118

We aimed to investigate mastication predominance in healthy dentate individuals and patients with unilateral posterior missing teeth using objective and subjective methods. The sample comprised 50 healthy dentate individuals (healthy dentate group) and 30 patients with unilateral posterior missing teeth (partially edentulous group). Subjects were asked to freely chew three kinds of test foods (peanuts, beef jerky and chewing gum). Electromyographic activity of the bilateral masseter muscles was recorded. The chewing side (right side or left side) was judged by the level of root mean square electromyographic amplitude. Mastication predominance was then objectively assessed using the mastication predominant score and the mastication predominant index. Self-awareness of mastication predominance was evaluated using a modified visual analogue scale. Mastication predominance scores of the healthy dentate and partially edentulous groups for each test food were analysed. There was a significant difference in the distribution of the mastication predominant index between the two groups (P < 0·05). The mastication predominant score was weakly correlated with self-awareness of mastication predominance in the healthy dentate group, whereas strong correlation was observed in the partially edentulous group (P < 0·05). The results suggest that the individuals with missing unilateral posterior teeth exhibited greater mastication predominance and were more aware of mastication predominance than healthy dentate individuals. Our findings suggest that an objective evaluation of mastication predominance is more precise than a subjective method. © 2016 John Wiley & Sons Ltd.

Posterior Open Bite Due to Failure of Maxillary Molar Eruption.

Yasumura, Toshihiko; Sueishi, Kenji

Posterior open bite can cause problems with occlusion. It arises from systemic or local factors such as physical or functional interference, ankylosis, and failure of eruption. Primary failure of eruption (PFE) is a rare condition that is difficult to differentiate from ankylosis and requires complex treatment strategies. Here we report a 12-year-old girl who was referred to our hospital by her dentist for re-evaluation of eruption failure of the left maxillary secondary premolar and first and second molars with congenitally missing maxillary lateral teeth. The maxillary first molar was extracted for a therapeutic diagnosis. The left maxillary secondary premolar and second molar reacted well to subsequent orthodontic treatment. Auto-transplantation of the mandibular premolar to the maxil-lary arch was carried out to achieve optimal overjet, overbite, and occlusion. The active treatment period spanned 4 years and 1 month. Assessment of the patient's medical and dental history, prior trauma, and clinical conditions resulted in a therapeutic diagnosis of PFE. Satisfactory orthodontic treatment results were achieved.

The present study evaluates the influence of several demographic, health, personal, and clinical factors on the number of missing teeth in old age sample. The number of patients included was 259; they received a full mouth examination and answered a questionnaire provided by one examiner. All the variables related to teeth loss based on the literature were included. These variables focused on age, gender, race, marital status, clinical attachment level, pocket depth, year of smoking, number of cigarettes smoked per day, number of medications, root decay, coronal decay, health status, and year of education. Statistical analysis involved stepwise multivariate linear regression. Teeth loss was statistically associated with clinical attachment level (CAL)(p value 0.0001), pocket depth (PD) (0.0007) and education level (0.0048). When smoking was included in the model, age was significantly associated with teeth loss (0.0037). At least one of these four factors was also related to teeth loss in several specific groups such as diabetes mellitus, male, and White. The multiple linear regressions for all the proposed variables showed that they contributed to teeth loss by about 23%. It can be concluded that less education or increased clinical attachment level loss may increase number of missing teeth. Additionally, age may cause teeth loss in the presence of smoking.

Tooth decay (TD) is common in children with significant consequences on systemic well-being, growth and quality of life, as well as increasing the risk of decay in the permanent teeth. The aim of the present study is to define risk factors associated with deciduous TD (DTD) in Iraqi preschool children. From the 1(st) June to 31(st) December 2012, a case-control study was carried out on 684 children under the age of 6 years who attended Al-Aulwyiah pediatric teaching hospital in Baghdad. Clinical examination and World Health Organization caries diagnostic criteria for decayed, missing and filled teeth (DMFT) were applied. Data including gender, residence, socio-economic status (SES), parental education level, parental smoking, tooth brushing frequency, type of feeding during infancy and the presence of any systemic disease in the child were sought. The mean DMFT score in the case group was 2.03 ± 1.39, of which decayed teeth formed 1.93. Males had a higher mean DMFT (2.10 ± 1.08) than females (1.96 ± 1.70) but with no statistically significant difference. The study revealed that residence, SES, parental education level and tooth brushing frequency were dependent risk factors significantly associated with DTD. However, gender, parental smoking and pattern of feeding during infancy were not significantly associated with DTD. Only four children with systemic disorders (1.2%), namely asthma and congenital heart diseases, were noticed to have DTD. Pediatricians and dentists could provide dental preventive and screening measures. Confronting relevant risk factors associated with DTD and improving access to oral care services are suggested. In addition, promotion of oral health programs through school curricula is needed.

The aim of this study was to assess whether current unemployment was associated with poor oral health and whether there was a difference in oral health according to the duration of the current unemployment. As part of the Health 2000 Survey in Finland (a nationwide comprehensive health examination survey), we used its data based on interviews, questionnaires, and clinical oral examinations of the 30- to 63-year-old respondents (n = 4773). Current employment status was measured in its dichotomous form, employed versus unemployed, and length of current unemployment was classified into four categories. We measured oral health in terms of numbers of missing teeth, of sound teeth, of filled teeth, of decayed teeth, and of teeth with deepened periodontal pockets (≥4 mm, ≥6 mm). Poisson regression models were fitted for all oral health outcomes except number of decayed teeth, for which negative binomial regression model was used. Oral health-related behaviors and sociodemographic and socioeconomic factors were added to the analyses. The unemployed subjects had higher numbers of missing teeth, of decayed teeth, and of teeth with periodontal pockets than the employed ones. The association remained consistent even after adjustments. Oral health-related behaviors seemed to mediate the association. We found no association between unemployment and number of sound teeth. Current long-term unemployment showed stronger association with poor oral health than short-term among women. The unemployed can be considered as a risk group for poor oral health. Oral healthcare should be reoriented toward those who are unemployed. © 2015 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

This article compares interracial or gender differences of six intraoral dental parameters among six racial groups (African American, Caucasian, Chinese, Hispanic, Japanese, and Korean). The same 253 patients participating in part 1 were included in this portion of the study to evaluate six intraoral parameters. The data were collected and analyzed using a one-way analysis of variance, followed by the Tukey-Kramer test for honestly significant difference when statistically significant differences were found (P < .05). Women displayed significantly more gingival tissue in four of the six races, and African Americans displayed significantly more gingival tissue than any other race. Women had significantly more missing teeth than men in three of the six races studied. Japanese subjects had significantly fewer missing teeth and smaller maxillary central incisors than all other groups except Caucasians. Women had significantly narrower maxillary central incisors in three of the races. There was a significantly higher prevalence of Angle Class III relationships in Chinese subjects. The Japanese had significantly more Class II molar relationships than other races. Racial and gender differences were found in gingival tissue display, the number of missing teeth, maxillary right central incisor crown width, and Angle molar classification, but not in the amount of vertical or horizontal overlap of the anterior teeth.

The oral health of military populations is usually not very well characterized compared to civilian populations. The aim of this study was to investigate two physical oral health characteristics and one perceived oral health measure and their correlation in the Japan self-defense forces (JSDF). Number of missing teeth, denture status, and OHRQoL as evaluated by the Japanese 14-item version of the Oral Health Impact Profile (OHIP-J14) as well as the correlation between these oral health measures was investigated in 911 personnel in the JSDF. Subjects did not have a substantial number of missing teeth and only 4% used removable dentures. The mean OHIP-J14 score was 4.6 ± 6.7 units. The magnitude of the correlation between the number of missing teeth with OHIP-J14 scores was small (r = 0.22, p < 0.001). Mean OHIP-J14 scores differed between subjects with and without dentures (8.6 and 4.4, p < 0.001). Compared to Japanese civilian populations, personnel of the JSDF demonstrated good oral health. Two physical oral health characteristics were associated with perceived oral health.

Limited information is available on the oral health status of upper income Americans (>400 percent of the FPL). They constitute 33 percent of the population and account for 53 percent of dental expenditures. Using 1999-2004 NHANES data, we examined differences in the mean number and percentage of decayed and filled permanent surfaces and missing teeth among age and family income groups. For upper income Americans, across age groups, the mean number of untreated decayed surfaces and missing teeth ranged from 0.2 to 0.5 and 2.6 to 3.3, respectively. The mean number of restored surfaces was low in children but extensive in adults. Income disparities increased with increasing age. Overall, upper income Americans have good oral health. Relatively few have untreated decayed surfaces or missing teeth. The reasons for the large number of restored surfaces in upper income adults require further research. Most upper income Americans are in good oral health, especially the 12-18 year cohort. As this group ages, the oral health of upper income adults is expected to improve. © 2015 American Association of Public Health Dentistry.

To compare prevalence and carriage of Candida species among gutka-chewers and betel-quid-chewers. The cross-sectional case-control study was conducted between January and December, 2015 at the Oral Surgery department of Abbasi Shaheed Hospital and the Dental department of Jinnah Postgraduate Medical Centre, Karachi, and comprised oral yeast samples of gutka-chewers, betel-quid-chewers, and non-chewers. A standardised questionnaire was used to gather demographic data and oral hygiene maintenance information. Oral Candida strains were collected, cultured and identified using standard techniques and yeast identification system. In all groups, unstimulated whole salivary flow rate was determined. Lesions on the tongue and oral mucosa were clinically investigated and numbers of missing teeth were recorded. SPSS 20 was used for data analysis. Of the total 185 samples, 50(27%) were from gutka-chewers, 50(27%)betel-quid-chewers, and 85(46%) non-chewers. Oral Candida carriage was comparable among betel-quid-chewers (18 [36%])and gutka-chewers (20 [40%]), but it was significantly higher than the non-chewers (11 [12.9%]) (p<0.05).Candida species were isolated from 45 (90%) of gutka-chewers and 45 (90%) of BQ-chewers. Among the groups, Candida albicans was the most commonly isolated yeast species (38% in gutka-chewers and 12.9% non-chewers). Mean numbers of missing teeth were significantly higher among BQ-chewers (6.8±0.4 teeth [range: 5-10]) (p<0.01) and gutka-chewers 6.8±0.6 teeth (range: 5-10) (p<0.01) than non-chewers (2.2±0.3 teeth [range: 0-3 teeth]). There was no significant difference in unstimulated whole salivary flow rate and the number of missing teeth among gutka-chewers and betel-quid-chewers (p>0.05). Prevalence and carriage of Candida species were comparable between betel-quid-chewers and gutka-chewers compared to non-chewers.

Dental caries in Arab League countries: a systematic review and meta-analysis.

PubMed

Khan, Soban Qadir

2014-08-01

The aim of this review was to determine prevalence of dental caries in primary and permanent teeth in the 2-20-year-old population of the Arab league. A literature search was performed on Pubmed, Summon and Google Scholar using the key words 'Dental caries', 'dmft' and 'DMFT'. A total of 293 articles were found, of which 35 passed our inclusion criteria and were included in analysis. Tables were made separately for primary and permanent teeth; the age group for primary teeth was 2-12 years and for permanent teeth 6-20 years. A meta-analysis was run by using data extracted from the studies included. Heterogeneity was tested by forest plot and chi-square test, and considerable heterogeneity was found. Mean decayed, missing and filled teeth (dmft) was 4.341 (95% CI 3.714, 4.969) and in permanent teeth (DMFT) was 2.469 (95% CI 2.019, 2.919) from a random effect model. Publication bias diagnostics suggested missing of four studies of primary teeth caries data and eight studies of permanent teeth caries data to obtain symmetry in the funnel plot. The incidence of caries in primary teeth was found to be high compared with caries in permanent teeth in the Arab League. This study does not provide a comprehensive picture of caries prevalence in the Arab League because in many of these countries only a few studies were performed. Therefore, these data cannot provide a complete picture of the prevalence of caries in those countries. Additional studies are needed to better evaluate the prevalence of caries in children and young adults in Arab League countries. © 2014 FDI World Dental Federation.

EDAR-induced hypohidrotic ectodermal dysplasia: a clinical study on signs and symptoms in individuals with a heterozygous c.1072C > T mutation

PubMed Central

2014-01-01

Background Mutations in the EDAR-gene cause hypohidrotic ectodermal dysplasia, however, the oral phenotype has been described in a limited number of cases. The aim of the present study was to clinically describe individuals with the c.1072C > T mutation (p. Arg358X) in the EDAR gene with respect to dental signs and saliva secretion, symptoms from other ectodermal structures and to assess orofacial function. Methods Individuals in three families living in Sweden, where some members had a known c.1072C > T mutation in the EDAR gene with an autosomal dominant inheritance (AD), were included in a clinical investigation on oral signs and symptoms and self-reported symptoms from other ectodermal structures (n = 37). Confirmation of the c.1072C > T mutation in the EDAR gene were performed by genomic sequencing. Orofacial function was evaluated with NOT-S. Results The mutation was identified in 17 of 37 family members. The mean number of missing teeth due to agenesis was 10.3 ± 4.1, (range 4–17) in the mutation group and 0.1 ± 0.3, (range 0–1) in the non-mutation group (p < 0.01). All individuals with the mutation were missing the maxillary lateral incisors and one or more of the mandibular incisors; and 81.3% were missing all four. Stimulated saliva secretion was 0.9 ± 0.5 ml/min in the mutation group vs 1.7 ± 0.6 ml/min in the non-mutation group (p < 0.01). Reduced ability to sweat was reported by 82% in the mutation group and by 20% in the non-mutation group (p < 0.01). The mean NOT-S score was 3.0 ± 1.9 (range 0–6) in the mutation group and 1.5 ± 1.1 (range 0–5) in the non-mutation group (p < 0.01). Lisping was present in 56% of individuals in the mutation group. Conclusions Individuals with a c.1072C > T mutation in the EDAR-gene displayed a typical pattern of congenitally missing teeth in the frontal area with functional consequences. They therefore have a need for special attention in dental care, both with reference to tooth agenesis and low salivary secretion with an increased risk for caries. Sweating problems were the most frequently reported symptom from other ectodermal structures. PMID:24884697

Treatment planning of implants in posterior quadrants.

PubMed

Jivraj, S; Chee, W

2006-07-08

Differences in anatomy and biomechanics make treatment of posterior quadrants with dental implants substantially different to that of anterior areas. Without implants, when posterior teeth were lost, treatment options included a long span fixed partial denture or a removable prosthesis, especially when no terminal abutment was available. Today, with the use of implants, options are available that allow preservation of unrestored teeth.(1) When teeth are missing, implant supported restorations can be considered the treatment of choice from the perspective of occlusal support, preservation of adjacent teeth and avoidance of a removable partial denture.

This clinical case report describes the multi-disciplinary approach in the management of an unusual presentation of idiopathic multiple unerupted impacted permanent teeth in a 20-year-old female patient. The case was unique in that, not only were there multiple missing permanent teeth, but also over retained deciduous teeth and attrited existing permanent teeth with loss of vertical dimension of occlusion. Since the patient was young, it was decided to retain all the erupted permanent teeth and extract the infected deciduous teeth with the objective of fabricating overlay complete dentures. This is a simple, reversible and an economical treatment modality, which satisfies both the esthetic and functional demands where the extraction of teeth is not generally indicated and, in addition, provides a stable occlusion.

A Curriculum Vitae of Teeth: Evolution, Generation, Regeneration

The ancestor of recent vertebrate teeth was a tooth-like structure on the outer body surface of jawless fishes. Over the course of 500,000,000 years of evolution, many of those structures migrated into the mouth cavity. In addition, the total number of teeth per dentition generally decreased and teeth morphological complexity increased. Teeth form mainly on the jaws within the mouth cavity through mutual, delicate interactions between dental epithelium and oral ectomesenchyme. These interactions involve spatially restricted expression of several, teeth-related genes and the secretion of various transcription and signaling factors. Congenital disturbances in tooth formation, acquired dental diseases and odontogenic tumors affect millions of people and rank human oral pathology as the second most frequent clinical problem. On the basis of substantial experimental evidence and advances in bioengineering, many scientists strongly believe that a deep knowledge of the evolutionary relationships and the cellular and molecular mechanisms regulating the morphogenesis of a given tooth in its natural position, in vivo, will be useful in the near future to prevent and treat teeth pathologies and malformations and for in vitro and in vivo teeth tissue regeneration.

ABSTRACT The purpose of the study was to investigate perceived teeth health status and oral health behavior, as well as their correlates, among adolescents in Cambodia. The analysis included 3806 Cambodian school children (mean age 15.7 years, SD=1.8 years) who took part in the “Global School-based Student Health Survey” (GSHS) in 2013. Overall, 7.8% of the students reported poor perceived teeth status, 18.0% had missed school in the past year because of a toothache, 26.7% engaged in combined oral health behavior (brushing teeth twice daily or more often = 79.8%, using fluoride toothpaste = 59.9%, and drinking soft drinks less than once a day = 53.6%), and 59.9% had never visited a dentist for a routine examination or other dental work. In the multivariate logistic regression analysis, older age, being female, missing school because of a toothache, having a toothache in the past 12 months, poor oral health behavior and sedentary leisure time were associated with poor perceived teeth status. Older age, good perceived teeth status, having had a dental check-up, washing hands before eating and after toilet use, and not eating fast food were associated with a positive oral health behavior (brushing teeth twice daily or more often, using fluoride toothpaste, and drinking soft drinks less than once a day). Significant proportions of poor perceived teeth status and poor oral health behavior were found among school children in Cambodia. Various risk factors (sociodemographic, dental variables, general health risk behaviors) for perceived poor teeth status, oral health behavior and never having had a dental check-up were identified, which can be utilized for intervention programs.

After tooth loss, an individual may seek tooth replacement so that his/her function and esthetics could be restored. Clinical prosthodontics, during the past decade, has significantly improved and developed according to the advancements in the science and patient's demands and needs. Conventional options in prosthodontics for substituting a missing single tooth include the removable partial denture, partial and full coverage bridgework, and resin-bonded bridgework. Dental implants have gained increasing popularity over the years as they are capable of restoring the function to near normal in both partial and completely edentulous arches. With substantial evidence available, fixed implant-supported prosthesis are fully acknowledged as a reliable treatment option for the replacement of single or multiple missing teeth nowadays. While dental implants are increasingly becoming the choice of replacement for missing teeth, the impediments associated with them are progressively emerging too. PMID:28435381

Multiple impacted permanent teeth are usually related to syndromes, metabolic and hormonal disorders. However, in some cases, impaction of multiple teeth is not associated with any syndrome. In this report, we present a case of 17-year-old male patient with missing teeth. Radiographs revealed multiple impacted permanent teeth, though medical and family history along with physical examination was not suggestive of any syndromes. If other investigations are negative, an idiopathic case of multiple impacted teeth is suggested to be the possible diagnosis. The objective of this report is to increase awareness of such cases especially in the absence of hereditary/genetic/metabolic factors usually inherent in such scenarios. The patient management in such cases needs to be planned specifically from a multidisciplinary standpoint. PMID:22438652

We determine the relationship between premature loss of primary teeth and oral hygiene, consumption of soft drinks, dental care and previous caries experience. This study focused on 833 Mexican schoolchildren aged 6-7. We performed an oral examination to determine caries experience and the simplified oral hygiene index. The dependent variable was the prevalence of at least one missing tooth (or indicated for extraction) of the primary dentition; this variable was coded as 0 = no loss of teeth and 1 = at least one lost primary tooth. The prevalence of at least one missing tooth was 24.7% (n = 206) (95% CI = 21.8-27.7). The variables that were associated with the prevalence of tooth loss (p < 0.05) included: the largest number of decayed teeth (OR = 1.11), the largest number of filled teeth (OR = 1.23), the worst oral hygiene (OR = 3.24), a lower frequency of brushing (OR = 1.60), an increased consumption of soda (OR = 1.89) and use of dental care (curative: OR = 2.83, preventive: OR = 1.93). This study suggests that the premature loss of teeth in the primary dentition is associated with oral hygiene, consumption of soft drinks, dental care and previous caries experience in Mexican schoolchildren. These data provide relevant information for the design of preventive dentistry programs.

A misconception exists in the society regarding the caries frequency during pregnancy. The condition of the teeth of the child can be influenced by the state of the teeth and the oral hygiene habits of the mother. An examination was conducted among young women soon after delivery in Szeged/Hungary. The number of the examined patients was 161, with the average age of 27.6 years. The DMFT (Decayed, Missing, Filled Teeth) index was 12.45, while the DMFS (Decayed, Missing, Filled Surfaces) index was 26.07 in the examined population. The DMFT index significantly correlated with age, number of pregnancies, plaque index, probing pocket depth and bleeding on probing, while the DMFT index was not dependent on education level, profession and place of residency. There was no significant correlation between the number of previous pregnancy and the incidence of caries.

Oral health in the Japan self-defense forces - a representative survey

Background The oral health of military populations is usually not very well characterized compared to civilian populations. The aim of this study was to investigate two physical oral health characteristics and one perceived oral health measure and their correlation in the Japan self-defense forces (JSDF). Methods Number of missing teeth, denture status, and OHRQoL as evaluated by the Japanese 14-item version of the Oral Health Impact Profile (OHIP-J14) as well as the correlation between these oral health measures was investigated in 911 personnel in the JSDF. Results Subjects did not have a substantial number of missing teeth and only 4% used removable dentures. The mean OHIP-J14 score was 4.6 ± 6.7 units. The magnitude of the correlation between the number of missing teeth with OHIP-J14 scores was small (r = 0.22, p < 0.001). Mean OHIP-J14 scores differed between subjects with and without dentures (8.6 and 4.4, p < 0.001). Conclusions Compared to Japanese civilian populations, personnel of the JSDF demonstrated good oral health. Two physical oral health characteristics were associated with perceived oral health.

The aim of the current study was to investigate the psychosocial impact of dental aesthetics among patients who received anterior implant-supported prostheses. The current study is a cross-sectional evaluation involving 115 individuals who had gone through treatment at the dental clinics of general hospitals. Participants completed the Chinese version of the psychosocial impact of dental aesthetics questionnaire (PIDAQ) before implantation and six months after crown restoration. Basic demographic information was recorded. Six months after implant crown restoration, participants were asked to self-assess their own oral aesthetics compared to before implantation. A total of 106 patients completed the study. PIDAQ scores correlated significantly with the self-assessment of the degree of oral aesthetics. Six months after crown restoration, the two factors (social impact and aesthetic attitude) decreased and the dental self-confidence score increased significantly compared to pre-implantation scores. Gender and education level significantly affected PIDAQ. Anterior implant-supported prostheses significantly affected the patients' psychosocial perception. Implantation of missing anterior teeth can significantly improve patients' negative psychosocial impact of dental aesthetics. Gender and education level are correlated with the degree of improvement. The PIDAQ can be used in assessing the psychosocial effects of implantation in missing anterior teeth.

This study examines the skeletal remains of a subadult from an archeological site in Austria. Radiocarbon dating and archeological attribution indicate that this individual is of pre-Columbian origin. Most of the skeleton was recovered, and only the teeth and the orbital roofs show changes. Dental defects such as the mulberry molar and a tapered, fang-like canine suggest a diagnosis of congenital syphilis. This is the first probable case of congenital syphilis from pre-Columbian Central Europe. Our findings contribute to the pre-Columbian theory, offering counter evidence to the assumption that syphilis was carried from Columbus' crew from the New to the Old World.

Dental diseases are among the most frequent diseases globally and tooth loss imposes a substantial burden on peoples' quality of life. Non-experimental evidence suggests that individuals with more children have more missing teeth than individuals with fewer children, but until now there is no causal evidence for or against this. Using a Two-Stage Least Squares (2SLS) instrumental variables approach and large-scale cross-sectional data from the Survey of Health, Ageing, and Retirement in Europe (study sample: 34 843 non-institutionalised individuals aged 50+ from 14 European countries and Israel; data were collected in 2013), we investigated the causal relationship between the number of biological children and their parents' number of missing natural teeth. Thereby, we exploited random natural variation in family size resulting from (i) the birth of multiples vs singletons, and (ii) the sex composition of the two first-born children (increased likelihood of a third child if the two first-born children have the same sex). 2SLS regressions detected a strong causal relationship between the number of children and teeth for women but not for men when an additional birth occurred after the first two children had the same sex. Women then had an average of 4.27 (95% CI: 1.08 to 7.46) fewer teeth than women without an additional birth whose first two children had different sexes. This study provides novel evidence for causal links between the number of children and the number of missing teeth. An additional birth might be detrimental to the mother's but not the father's oral health. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2018.

Oral diseases not only cause pain, but severely impair large number of individuals and can affect various aspects of life, including oral functions, appearance and interpersonal relationships. The aim of the study was to assess the interrelationship between oral impact on daily performance (OIDP) scores, socio-demographic characteristics, dental caries experience and periodontal status. A cross-sectional descriptive epidemiological study was conducted on a sample of 250 white-collar port workers who were willing to participate. OIDP was assessed using pre-validated questionnaire. Oral health status was assessed using modified World Health Organisation (1997) Proforma. Test of association was conducted between the OIDP score, socio-demographic variables, and periodontal status; loss of attachment was determined by using chi-square statistics and Mann-Whitney test. Logistic regression was performed to identify significant predictors of OIDP scores by inputting clinical oral examination variables into the equation, stepwise. A total of 250 white-collar workers in the port participated in the study with mean age of 34.67 ± 6.36. Among them, 219 were males and 31 were females. The OIDP items most commonly affected by oral health status were eating and enjoying food (48.4%), cleaning teeth (48%), sleeping and relaxing (44.4%).There was statistically significant relationship between missing teeth in the decayed missing filled teeth component and OIDP score (p < 0.001). The participants with caries have a greater odd (2.11) of having OIDP score ≥ 1 than those without caries. The participants with missing teeth have a greater odd (3.60) of having OIDP score ≥ 1. The participants in the age group of 31-40 years had a greater odd (2.80) of having OIDP score ≥ 1. Oral health had an impact on the quality of life of white-collar workers in the port. Physical functions of teeth like eating and cleaning of teeth, sleeping and relaxing were more affected.

To assess the impact of dental pain on the daily living of 5-year-old preschool children using reports from parents/guardians. A cross-sectional study was carried out involving 549 five-year-old children randomly selected from preschools in the city of Belo Horizonte, Brazil. Data were collected using a previously validated parent-reported questionnaire. The children received dental examinations from a single calibrated examiner. The following outcome variables were selected: age, gender, dental caries, filled teeth, missing teeth, caries involving pulp and social class. Simple and multiple logistic regression analyses were performed on the data. According to parents' reports, 11.1% of children were affected by dental pain in the previous 4 months and of these 72.6% had their daily activities hampered by pain. The majority of these children had difficulty in eating, brushing teeth, sleeping, playing and going to school. The impact of dental pain had a statistically significant association with gender (p=0.001), social class (p=0.009), dental caries (p<0.001), missing teeth (p<0.001), filled teeth (p<0.001) and caries involving pulp (p<0.001). The prevalence of difficulties performing tasks of daily living due to dental pain was relatively high among the children studied.

We present a case of pure erythroleukemia, diagnosed at autopsy, in a dysmorphic premature infant who died of multiorgan failure within 24 hours of birth. Dysmorphic features included facial and limb abnormalities with long philtrum, microagnathia, downturned mouth, short neck as well as abnormal and missing nails, missing distal phalanx from the second toe, and overlapping toes. Internal findings included gross hepatomegaly and patchy hemorrhages in the liver, splenomegaly, and cardiomegaly; and subdural, intracerebral, and intraventricular hemorrhages. Histology revealed infiltration of bone marrow, kidney, heart, liver, adrenal, lung, spleen, pancreas, thyroid, testis, thymus, and placenta by pure erythroleukemia. Only 6 cases of congenital erythroleukemia have been previously reported with autopsy findings similar to those of this case. The dysmorphic features, although not fitting any specific syndrome, make this case unique. Congenital erythroleukemia and possible syndromes suggested by the dysmorphic features are discussed.

The aim of this study was to present epidemiological parameters of caries prevalence in children and adolescents in index age groups on a national and regional level in Bosnia and Herzegovina (BH). The study was conducted during 2004 year for children aged 6 and 12, and during 2007 for adolescents aged 15. An oral health survey was performed on a total number of 1,240 children and adolescents in line with World Health Organization methodology and criteria. Results for caries prevalence and treatment needs were presented and discussed in this paper. Mean dmft (decay, missing, filled teeth for primary dentition) for children aged six was 6.7 (SD±3.9) in that the decayed teeth constituted the major part of the index (88.8%), followed by extracted teeth (8.9%) and a small percentage of filled teeth (2.3%). In 12-year-olds DMFT (Decay, Missing, Filled Teeth for permanent dentition) was 4.2 (SD±2.9), Significant Caries index (SiC) was 7.7 (SD±2.9), the decayed teeth constituted the major part of the index (45.4%), followed by 42.1% of FT and 12.5% of extracted teeth. Among 15-year-olds the DMFT was 7.6 (SD±4.1), SiC was 9.2 (SD±1.2), and filled teeth constituted the major part of the index. The present study provides some evidence of relatively high caries prevalence and severity in comparison with Western European countries. It is necessary to devote more attention to the oral health of children and adolescents. Community based oral health promotion, preventive programs and preventive oriented public dental health care services should be made available and accessible to all children in Bosnia and Herzegovina.

To evaluate functional and periodontal aspects in patients with unilateral or bilateral congenitally missing maxillary lateral incisors, treated with either implants or space closure and tooth re-contouring. The sample consisted of 68 volunteers, divided into 3 groups: SCR - space closure and tooth re-contouring with composite resin (n = 26); SOI – implants placed in the area of agenesis (n = 20); and CG - control group (n = 22). A modified Helkimo questionnaire and the Research Diagnostic Criteria for Temporomandibular Disorders were used by a single, previously calibrated evaluator to assess signs and symptoms of temporomandibular joint disorder. The periodontal assessment involved the following aspects: plaque index, bleeding upon probing, pocket depth greater than 3 mm, gingival recession, abfraction, periodontal biotype and papilla index. The data were analyzed using Fisher's exact test and the nonparametric Mann-Whitney and Kruskal-Wallis tests (α=.05). No differences in periodontal status were found between treatments. None of the groups were associated with signs and symptoms of temporomandibular joint disorder. Both treatment alternatives for patients with congenitally missing maxillary lateral incisors were satisfactory and achieved functional and periodontal results similar to those of the control group.

We determine the relationship between premature loss of primary teeth and oral hygiene, consumption of soft drinks, dental care and previous caries experience. This study focused on 833 Mexican schoolchildren aged 6–7. We performed an oral examination to determine caries experience and the simplified oral hygiene index. The dependent variable was the prevalence of at least one missing tooth (or indicated for extraction) of the primary dentition; this variable was coded as 0 = no loss of teeth and 1 = at least one lost primary tooth. The prevalence of at least one missing tooth was 24.7% (n = 206) (95% CI = 21.8–27.7). The variables that were associated with the prevalence of tooth loss (p < 0.05) included: the largest number of decayed teeth (OR = 1.11), the largest number of filled teeth (OR = 1.23), the worst oral hygiene (OR = 3.24), a lower frequency of brushing (OR = 1.60), an increased consumption of soda (OR = 1.89) and use of dental care (curative: OR = 2.83, preventive: OR = 1.93). This study suggests that the premature loss of teeth in the primary dentition is associated with oral hygiene, consumption of soft drinks, dental care and previous caries experience in Mexican schoolchildren. These data provide relevant information for the design of preventive dentistry programs. PMID:26916132

2012-03-01

The loss of all teeth from one or both dental arches is a significant disability affecting self-confidence, communication, masticatory function and aesthetics. Whilst missing teeth cannot be restored to the natural state, the development of a prosthetic dentition has been a goal of dental science throughout the centuries. Contemporary techniques allow for the replacement of missing dentition with fixed or removable solutions, solving many of the problems. Implant dentistry has transformed this area of medicine. This article provides dental practitioners with an overview of this important area of patient care. Dental practitioners in clinical practice will frequently see edentulism; a good understanding of the available options for rehabilitation is essential.

A cross-sectional survey, using cluster sampling technique, of slum population, was done to explore the oral health status and the prevalence of common oral diseases. A close ended questionnaire comprising Decayed, Missing and Filled Teeth (DMFT) Index, Gingival Index (Löe and Silness) and Plaque Index was applied to evaluate and record oral diseases, in both male and female population, covering a wide range of age groups. Clinical examination was carried out in different shum set ups, including slum schools by trained and calibrated examiners. Three thousand nine hundred and four (3904) slum dwellers participated in the survey. Prevalence of Caries was expressed in mean DMFT, recording of gingival status followed the method of Löe and Silness, oral hygiene status was evaluated using Plaque index. Mean decayed component, of the DMFT, was significantly higher than filling and missing component. Both decayed and missing components showed increasing trend, and filling components decreased as the age progressed. Prevalence of gingivitis and plaque accumulation was remarkably high among slum dwellers. Significantly high level of common oral diseases was found among Tongi slum dwellers.

Williams syndrome is a multisystemic rare genetic disorder caused by deletion of 26-28 genes in the long arm of chromosome 7. It is characterized by developmental and physical abnormalities including congenital cardiovascular abnormalities, mental retardation, neurological features, growth deficiency, genitourinary manifestations, gastrointestinal problems, musculoskeletal problems, unique behavioral characteristics, and dental problems. Dental abnormalities include malocclusion, hypodontia, malformed teeth, taurodontism, pulp stones, increased space between teeth, enamel hypoplasia, and high prevalence of dental caries. Authors report a 17-year-old female patient with underlying Williams syndrome. Oral features and problems seen in the patient are listed. Malocclusion and screwdriver shaped teeth were noticed. Generalized widening of the periodontal ligament space with vital teeth was seen. This finding has not been reported in cases of Williams syndrome earlier. Precautions taken during dental treatment in patients with Williams syndrome are also discussed.

In some skeletal Class III adult patients with nasomaxillary hypoplasia, the LeFort I osteotomy provides insufficient correction. This case report describes a 20-year-old woman with a combination of nasomaxillary hypoplasia and a protrusive mandible with a congenitally missing mandibular second premolar. We performed a LeFort II osteotomy for maxillary advancement. Autotransplantation of a tooth was also performed; the donor tooth was used to replace the missing permanent tooth. To increase the chance of success, we applied light continuous force with an improved superelastic nickel-titanium alloy wire technique before extraction and after transplantation. The patient's profile and malocclusion were corrected, and the autotransplanted tooth functioned well. The postero-occlusal relationships were improved, and ideal overbite and overjet relationships were achieved. The methods used in this case represent a remarkable treatment.

Sri Lanka is a middle income country and 80% of its population lives in rural areas. There is a well organized maternal and child health program and oral health care has recently been incorporated. The aim of this study was to report the oral disease burden of rural and urban antenatal women in the Western Province of Sri Lanka, thus highlighting the need to provide oral health care to this group. The sample consisted of 459 rural pregnant women in their second trimester and 348 urban pregnant women in their third trimester. Data were collected using interviewer administered questionnaires and a clinical oral examination conducted by calibrated examiners. The mean Decayed Missing and Filled Teeth (DMFT) among rural antenatal women were 5.4 ± 3, with 2.27 (± 2.31) decayed teeth, 1.25 (± 1.97) missing teeth, and 1.90 (± 1.89) filled teeth. Among urban antenatal women, the mean DMFT was 3.69 (± 3.62) with 1.04 (± 2.15) decayed teeth, 1.07 (± 1.59) missing teeth and 1.59 (± 2.06) filled teeth. Rural antenatal women had a significantly higher experience of decayed teeth (p=0.001) and filled teeth (p=0.026), and twice as many untreated dental caries, compared with urban women. Moreover, almost 60% of rural women presented with bleeding gums. Similarly, the prevalence of calculus was 30.3% for rural women and 13.5% for urban women. The most significant finding was 3.5% prevalence of shallow periodontal pockets (4-5 mm) for rural women but 73.0% for urban women (p=0.0001). In the final model of multiple logistic regression analysis, significant predictors for dental caries experience were age (adjusted OR [95% CI]: 2.51 [1.55-4.06], p=0.0001) and location (urban vs rural adjusted OR [95% CI)]: 0.25 [0.11-0.55], p=0.001). However for periodontal status the only significant association was between age and Community Periodontal Index of Treatment Needs (CPITN): CPITN=0 versus CPITN>0 in bivariate analysis for the overall sample (p=0.001). Antenatal women in Sri Lanka have a high burden of dental caries and periodontal disease. Rural women had as twice as many untreated dental caries compared with urban women, but were unlikely to use oral healthcare services due to concerns about safety in receiving dental care during pregnancy. Oral healthcare provision to antenatal women in Sri Lanka can be improved.

A new documentation system for congenital absent digits.

PubMed

Jones, Neil F; Kaplan, Jesse

2012-12-01

Congenital absent digits continue to be described by many confusing terms and are currently classified in categories I, V, and VI of the International Federation of Societies for Surgery of the Hand classification and seven subclassification systems. Very few classification systems provide any logical basis for surgical reconstruction. The purpose of this study was to develop a simple alphanumerical documentation system to reproducibly describe the morphological or radiographic appearance of congenital absent digits and facilitate communication of these childrens' hand anomalies from one hand surgeon to another. Dorsal and palmar photographs and PA radiographs of 235 hands in 204 children born with congenital absent digits over a 15-year period were analyzed to determine which digital rays were missing and their level of absence. Each hand can be described by three letters, R (radial), C (central), and U (ulnar), as well as numbers 1-5. The first letter and number designate which rays are missing and the second and third letters and numbers designate which rays remain present. There are 15 morphological phenotypes of congenital absent digits. The three most common phenotypes are U4R1 (a thumb but absence of all four fingers), R1U4 (absent thumb), and R5 (aplastic hand). This new documentation system allows hand surgeons to describe the simple morphological or radiographic appearance of congenital absent digits; incorporates all the previous subclassification systems that have attempted to describe congenital absent digits in radial, central, and ulnar deficiencies, symbrachydactyly, and congenital constriction ring syndrome; and has subsequently allowed the development of an algorithm which predicts whether conventional or microsurgical reconstruction is indicated for each specific phenotype.

Most state Medicaid programs reimburse nondental primary care providers (PCPs) for providing preventive oral health services to young children. We examined the association between who (PCP, dentist, or both) provides these services to Medicaid enrollees before age 3 years and oral health at age 5 years. We linked North Carolina Medicaid claims (1999-2006) to oral health surveillance data (2005-2006). Regression models estimated oral health status (number of decayed, missing, and filled primary teeth) and untreated disease (proportion of untreated decayed teeth), with adjustment for relevant characteristics and by using inverse-probability-of-treatment weights to address confounding. We analyzed data for 5235 children with 2 or more oral health visits from a PCP, dentist, or both. Children with multiple PCP or dentist visits had a similar number of overall mean decayed, missing, and filled primary teeth in kindergarten, whereas children with only PCP visits had a higher proportion of untreated decayed teeth. The setting and provider type did not influence the effectiveness of preventive oral health services on children's overall oral health. However, children having only PCP visits may encounter barriers to obtaining dental treatment.

Evidence consistently shows that diabetes is a risk factor for increased prevalence of gingivitis and periodontitis. But there is a controversy about the relationship between diabetes related factors and periodontal health. The aim of the present study is to explore the relationship between diabetes related factors such as glycosylated hemoglobin, fasting blood glucose, duration of diabetes and compliance to diabetes self management and periodontal health status. Periodontal health of 125 participants with type-2 diabetes mellitus was measured by the number of missing teeth, community periodontal index (CPI), Russell's periodontal index and papillary bleeding index. Information on sociodemographic factors, oral hygiene behavior, duration and compliance to self management of diabetes, levels of glycosylated hemoglobin(HbA1c) and fasting blood glucose(FBG) were collected by interview and hospital medical records. Statistically, independent t-test, an analysis of variance (ANOVA), chi-squared test and multiple regression analyses were used to assess the association between diabetes-related factors and periodontal health. Periodontal parameters including the number of missing teeth and papillary bleeding index were significantly influenced by duration of diabetes, FBG and compliance to self management of diabetes. CPI was significantly influenced by duration of diabetes, FBG and HbA1C. And Russell's periodontal index was significantly influenced by duration of diabetes, FBG, HbA1C and compliance to self management of diabetes. Results of multiple linear regression analysis showed that the duration of diabetes showed significant positive correlation with all of the periodontal health parameters, except for missing teeth. HbA1c was correlated with Russell's periodontal and papillary bleeding index. FBG and compliance to self management of diabetes were correlated with missing teeth and papillary bleeding index respectively. Diabetes-related factors such as duration of diabetes, FBG, HbA1c and compliance to self management of diabetes were significantly correlated with periodontal health among individuals with type-2 diabetes.

The aims of this study were to investigate the frequency and characteristics of dental transpositions and to evaluate associated dental anomalies in a large sample of Turkish Anatolian population. A retrospective study was performed using panoramic radiographs of 6983 patients (4092 females and 2891 males) ranging in age from 12 to 27 subjected to Faculty of Dentistry at the University of Ataturk (Erzurum, Turkey) between 2005 and 2008. For each patient with tooth transposition we recorded the demographic variables (including age, sex), history of trauma, type, classification, and location of tooth transpositions, and associated dental anomalies. The Pearson chi-squared test was used to determine potential differences in the distribution of tooth transposition when stratified by gender. Tooth transposition was detected in 19 subjects (0.27%), with a 2.2:1 female male ratio (P=0.38). The most commonly observed transposition was maxillary canine-lateral incisor (60%). The frequencies of complete and incomplete transpositions were equal (10/10) and it was more common in the left side than in the right side (11/9). Of the 19 subjects, 10.5% had a peg shaped lateral incisor, 21.1% one congenitally missing tooth excluding third molar. Supernumerary tooth, impacted teeth excluding third molars, transmigrated tooth, and dilacerations were also observed. The frequency of tooth transposition was 0.27% in a Turkish Anatolian population and maxillary canine-lateral incisor was the most frequently observed transposition. Retained primary teeth were the most frequently observed dental anomaly in all types of tooth transposition.

Dental anomalies associated with different severities of cleft lip and palate have been rarely reported. This retrospective study investigates the characteristics of dental anomalies associated with different types of cleft, and compares the dental anomaly traits based on sex and severity of cleft. Cleft patients born in 1995 with qualified diagnostic records from 7 to 11 years were included for evaluation. Records were retrieved from database of Chang Gung Craniofacial Center, including panoramic radiographs and intraoral photographs. In total, 196 patients with complete records were included in the evaluation. This study compares the dental anomalies associated with each type of cleft. The frequency of dental anomalies in the maxillary incisor area in the cleft palate (CP) group (20%) was significantly lower than that in other groups. The frequency of missing maxillary lateral incisors (MLIs) increased as the cleft severity increased. Supernumerary teeth and missing lower incisors exhibited the opposite trend. No sexual dimorphism appeared in terms of the frequencies of peg laterals and missing MLIs. The distribution patterns of missing MLIs and peg laterals in males, but not in females, were consistent for the three types of unilateral clefts. Regarding the characteristics of dental anomalies among the three unilateral clefts, missing MLIs, supernumerary teeth, and missing lower incisors were found to be related to cleft severity. The maxillary lateral incisor was the most affected tooth in the cleft area. The frequency of missing MLIs and peg laterals was not sexual dimorphic, but the distribution pattern was different between the sexes.

Today's society is becoming increasingly unsafe for children: we frequently hear about new incidents of missing children, which lead to emotional trauma for the loved ones and expose systemic failures of law and order. Parents can take extra precautions to ensure the safety of their children by educating them about ways to protect themselves and keep important records of the child such as updated color photographs, fingerprints, deoxyribonucleic acid (DNA) samples, etc., handy. However, in spite of all efforts, the problem of missing children still remains. Developments in the field of dentistry have empowered dentists with various tools and techniques to play a pivotal role in tracing a missing child. One such tool is Toothprints, a patented arch-shaped thermoplastic dental impression wafer developed by Dr. David Tesini, a paediatric dentist from Massachusetts. Toothprints enables a unique identification of the missing children not only through the bite impression but also through salivary DNA. Besides the use of Toothprints, a dentist can assist investigating agencies in identifying the missing children in multiple ways, including postmortem dental profiling, labeled dental fixtures, DNA extraction from teeth, and serial number engraving on the children's teeth. More importantly, all these tools cause minimal inconvenience to the individual, making a dentist's role in tracking a missing child even more significant. Thus, the simple discipline of maintaining timely dental records with the help of their dentists can save potential hassles for the parents in the future.

This is a cross-sectional population-based study (n = 763) conducted in the north of the State of Minas Gerais, which aimed to investigate the prevalence of tooth decay among adolescents and to identify the potential determinants of same. Probability sampling by conglomerates in multiple stages was used. Trained and calibrated professionals performed the data collection by means of intraoral examination and interviews in the previously selected households. In the analysis of the determinant factor for the presence of tooth decay, hierarchical binary logistic regression models were used. The prevalence of tooth decay, decayed, missing and filled teeth were 71.3%, 36.5%, 55.6% and 16%, respectively. The following averages were observed: DMFT (3.4 teeth), number of decayed (0.8 teeth), restored (2.4 teeth) and missing (0.2 teeth). The incidence of tooth decay was higher among adolescents who stated they were black/indigenous/brown (OR = 1.76), lived in crowded households (OR = 2.4), did not regularly visit or had never been to a dentist (OR = 1.9), used public or philanthropic services (OR = 1,8), had smoking habits (OR = 4.1), consumed alcohol (OR = 1.8), perceived their oral health negatively (OR = 5.9 and OR = 1.9) and had toothac in the last six months (OR = 2.0).

To examine the disutility of tooth loss. It compared how people value their teeth in two countries which are culturally similar in order to explore the effect of culture on self-perceptions of oral health. Cross sectional study. Participants were recruited from subjects attending two hospitals in Turkey and in Iran. Nineteen descriptions of mouths with varying degrees and types of tooth loss were presented to the participants. They were shown mouth models of partially edentate dentitions and the teeth missing were explained in relation to the participants own mouth. The participants were specifically asked to consider the role their teeth played in function (chewing), communication (speech) and aesthetics (looks) along with "all the other things that make your mouth important". The participants were asked to indicate on a visual analogue scale how they would value the health of their mouth if they lost the tooth/teeth described and the resultant space was left unrestored. Overall 152 subjects participated, 78 in Turkey and 74 in Iran with 83 being female and 69 male. Their mean age was 29.5 years (SD 9.3), 62.5% had experienced tooth loss and 37.5% had complete (or completely restored) dentitions. Although there were no differences between the two countries in the degree of utility people attached to anterior teeth, Turkish participants attached significantly more disutility than Iranians to the loss of premolar and molar teeth (p < 0.003). Country of origin had an influence on the value placed on certain parts of the dentition and this effect is independent of the number of missing teeth, gender and age. This implies that attitudes to oral health are influenced by prevalent cultural attitudes more than by function.

Congenital diverticula of the left ventricle, very rare malformations, are determined by an abnormal embryonic development of the ventricular wall and can be isolated or associated to other cardiac anomalies. In most of the cases, these pathologies are not symptomatic and in some patients can be associated to ventricular arrhythmia, cardiac rupture with tamponade and sudden death. Authors are presenting the case of a sudden death in an 8-weeks-old newborn due to rupture of a cardiac congenital diverticulum of the left ventricle, discovered only at the moment of the autopsic examination. The parents of the victim pressed charges against the medical staff that was appointed to the cares, blaming them with malpractice. The missed diagnosis of a cardiac congenital diverticulum of the left ventricle, a rare pathology, reflects the trickiness of the medical management that can lead to medico-legal controversies and, even though such rare conditions must be always taken into consideration when investigating possible dysfunction causing the death, diagnostic difficulties, in the case in exam, justify the missed diagnosis intra-vitam of cardiac ventricular diverticulum.

Supernumerary teeth (ST) are odontostomatologic anomaly characterized by as the existence excessive number of teeth in relation to the normal dental formula. This condition is commonly seen with several congenital genetic disorders such as Gardner's syndrome, cleidocranial dysostosis and cleft lip and palate. Less common syndromes that are associated with ST are; Fabry Disease, Ellis-van Creveld syndrome, Nance-Horan syndrome, Rubinstein-Taybi Syndrome and Trico-Rhino-Phalangeal syndrome. ST can be an important component of a distinctive disorder and an important clue for early diagnosis. Certainly early detecting the abnormalities gives us to make correct management of the patient and also it is important for making well-informed decisions about long-term medical care and treatment. In this review, the genetic syndromes that are related with ST were discussed.

The National health insurance law enacted in 1995 did not include dental care in its basket of services. Dental care for children was first included in 2010, initially up till 8 years of age. The eligibility age rose to 12 years in 2013. The dental survey of 6 year-olds in 2007 found that the average of decayed, missing and filled teeth index (dmft) was 3.31 and 35 % of children were caries free. The current cross sectional survey of dental health for 6 year-olds was conducted as a comparison to the pre-reform status. Twenty-three local authorities were randomly selected nationwide. Two Grade 1 classes were randomly chosen in each. The city of Jerusalem was also included in the survey because of its size. The children were examined according to the WHO Oral Health Survey Methods 4th ed protocol. The dental caries index for deciduous teeth (dmft: decayed, missing, filled teeth) was calculated. One thousand two hundred ten children were examined. 61.7 % of the children suffered from dental decay and only 38.3 % were caries free. The mean dmft was 2.56; d = 1.41 (teeth with untreated caries), f = 1.15 (teeth damaged by decay and restored), virtually none were missing due to caries. Dental caries prevalence was rather consistent, an average of over 2 teeth affected per child. Although there is no major change in comparison to former surveys, there is more treated than untreated disease. In the present survey the f component is higher than in the past, especially in the Jewish sector where it is the main component. It is still lower in the Arab sector. Although the level of dental disease remained rather constant, an increase in the treatment component was observed. In order to reduce caries prevalence, preventive measures such as school dental services and drinking water fluoridation should be extended and continued. Primary preventive dental services should be established for children from birth, with an emphasis on primary health care and educational settings, such as family health centers and kindergartens.

Recently, some studies have demonstrated the efficacy of this new method in reducing congenital abnormalities with specific origin; for example, in the offspring of diabetic and epileptic mothers, and in pregnancy with high fever. The benefits and drawbacks of four possible uses of periconception folate/folic acid and multivitamin supplementation are discussed: we believe there has been a missed opportunity to implement this preventive approach in medical practice. The four methods are as follows: (i) dietary intake of folate and other vitamins, (ii) periconception folic acid/multivitamin supplementation, (iii) food fortification with folic acid, and (iv) the combination of oral contraceptives with 6S-5-methytetrahydrofolate (‘folate’).

To determine the prevalence of congenital heart defects (CHDs) in patients with mild or severe congenital anorectal malformations (CARMs), and whether all patients with CARM need pediatric cardiology screening. We included 129 patients with CARM born between 2004 and 2013, and referred to University Medical Center Groningen. Recto-perineal and recto-vestibular fistulas were classified as mild CARMs, all others as severe. Significant patent foramen ovale, secundum atrial septal defect, and small ventricular septum defect were classified as minor CHDs, all others as major. Of 129 patients with CARM, 67% had mild CARM, 33% severe CARM, and 17% were additionally diagnosed with CHD. CHDs were distributed equally in patients with mild or severe CARMs. Patients with multiple congenital abnormalities were more frequently diagnosed with CHD (n = 16, 36%) than patients without multiple congenital malformations (n = 5, 9%, P = .001). Patients with CARM diagnosed with CHD using pediatric cardiac echo screening were younger than 3 months of age at diagnosis. Earlier general pediatric examinations missed 7 (50%) children with mild and 4 (50%) with severe CHDs. The severity of CARM could predict neither prevalence nor severity of CHD. More than one-half of CHDs were missed during the first physical examination. No new CHDs were found in patients older than 3 months of age at the time CARMs were diagnosed. We recommend screening all patients with CARM younger than 3 months of age for CHD at the time CARM is diagnosed. Preoperative echocardiography should be the rule in children younger than 3 months of age and with multiple congenital anomalies. Copyright © 2016 Elsevier Inc. All rights reserved.

Treatment planning: implant-supported partial overdentures.

When multiple anterior teeth are missing, many options of replacement are available. Traditionally, the choice was between a fixed or removable prostheses. Today, with the predictability of dental implants, the options of tooth replacement range from removable partial dentures to implant-supported fixed prostheses. The choice of which restoration that will best provide occlusion and esthetics depends on multiple factors including the number and location of missing teeth, the residual ridge form in relation to the replacement teeth, the relationship of the maxillary and mandibular anterior teeth, the condition of teeth adjacent to the edentulous span, the amount of bone available for implant placement, the patients "smile line" and display of teeth, lip support, and financial constraints. When there is minimal loss of the ridge contour, restorations that emerge from the ridge are the most functional and esthetic restorations, adhesive-type fixed partial dentures, conventional fixed partial dentures, and implant-supported restorations can be indicated with the choice of restoration dependent on a risk benefit and cost benefit analysis. When there is a loss of ridge contour due to residual ridge resorption or trauma, the decision becomes more complex as not only does the tooth structure need to be replaced, the ridge form also has to be replaced. (Figures 1 and 2). This can be assessed clinically as illustrated by Figures 1 and 2 where a dis crepancy in arch form and ridge form in relation to the adjacent teeth and/or opposing arch can be observed. Other considerations are lip support and display of the teeth when smiling. This article presents a case and rationale for implant-supported par tial overdentures. Many authors have written on the merits of com plete overdentures. The complete overdenture has proven to be an improvement over conventional complete prostheses with respect to chewing efficiency, patient comfort and satisfaction. In partial edentulism, the implant-supported overdenture has several advantages, some in common with a removable partial denture.

The aim of this study was to determine the caries rate and periodontal status in a sample of pregnant women with HIV+ infections from Puerto Rico. A pilot study was conducted on a cross sectional convenience sample of 25 pregnant women with HIV+ infections from Puerto Rico who visit the CEMI clinic (Centro de Estudios Materno Infantil) at the University of Puerto Rico. The women subjects were evaluated for caries, DMFT (D: Decay tooth; M: Missing tooth due to caries; F: Filled tooth) index, oral lesions associated with HIV+/AIDS and periodontal disease parameters, with a Florida probe by a calibrated dentist on periodontal indexes such as as bleeding on probing, CEJ (cemento-enamel junction) and pocket depth. Periodontal disease was classified as having 4 sites with pocket depth greater than 4 mm and caries were identified following the Radike criteria. Data was statistically analyzed using the SSPS Program (Statistical Software Program for Social Sciences) and descriptive statistics were calculated. Mean DT (decayed teeth), MT (missing teeth due to caries), FT (filled teeth) and DMFT (decay, missing and filled teeth) were 4.8, 1.86, 5.3 and 12, respectively; mean sites of bleeding on probing=12.06; mean sites with pocket depth>4 mm=6.95 and mean sites with loss of attachment greater than 4 mm=7.66. [Almost 50% of the patients had generalized chronic periodontitis. A 72% prevalence of periodontal disease was found. No oral lesions related to HIV+/AIDS were reported. CD4 and viral load was statistically associated with bleeding on probing and severe signs of periodontal disease. High levels of dental disease were found in pregnant women with HIV+/AIDS infections from Puerto Rico, and these women were in need of substantial dental services.

The aim of the present study was to investigate the effect of dental caries experience and the components of the decayed, missing and filled teeth (DMFT) index on oral health-related quality of life (OHRQoL) among adolescents in southern Brazil. A cross-sectional study was conducted with 509 adolescents aged 11-14 years enrolled at public schools in the municipality of Osório (southern Brazil). A calibrated examiner performed the clinical examination for caries (World Health Organization: DMFT index), malocclusion (Dental Aesthetic Index) and traumatic dental injuries [Andreasen et al., 2007]. The participants answered the Brazilian version of the Child Perceptions Questionnaire (CPQ11-14) - Impact Short Form, and their parents/guardians answered a structured questionnaire addressing demographic and socioeconomic characteristics. Data analysis involved Poisson regression with robust variance, with the calculation of rate ratios adjusted for potential confounding variables. High severity of dental caries experience exerted a significant impact on OHRQoL, even after controlling for socioeconomic and clinical factors (rate ratio 1.30; 95% confidence interval, CI 1.12-1.51). All OHRQoL domains were affected by untreated dental caries. The multivariate analysis demonstrated that the CPQ11-14 scores were 33% higher among adolescents with untreated caries (rate ratio 1.33; 95% CI 1.17-1.50) and 24% higher among those with missing teeth (rate ratio 1.24; 95% CI 1.06-1.47). No difference in OHRQoL was found between adolescents with filled teeth and those without dental caries. In conclusion, dental caries experience, untreated dental caries and missing teeth exerted a negative impact on OHRQoL among the adolescents. © 2016 S. Karger AG, Basel.

Experience and awareness of adult females concerning dental caries is important in its prevention particularly in children because of their natural role as care givers. To determine the prevalence of dental caries and treatment needs in an adult female Nigerian population. In this cross-sectional study, adult females attending outreach programmes were examined for dental caries using the Decayed Missing and Filled Teeth caries index (DMFT). Socio-demographic variables were also recorded and statistical analysis done with SPSS software. A total of 430 females aged 16 to 59 years participated in the outreach programme out of which 109 (25.3%) had a DMFT score > 0. Mean DMFT was 0.7 ± 1.6. Fifty-five (12.8%) participants had decayed teeth, 78 (18.1 %) had missing teeth and 10(2.3%) had filled teeth. The treatment need was 34.3%, restorative index was 13.3% and significant caries index was 2.0. There were significant differences in caries experience based on age, marital status and educational qualifications of participants p < 0.05. The prevalence of dental caries among the study group was low but the treatment need was high. Younger females, singles and those with lower educational qualifications had a higher dental caries experience.

Background Maternal syphilis has an important impact on reproductive health. In 2010, World Health Organization (WHO)/Pan American Health Organization (PAHO) member countries approved the Strategy and Plan of Action for Elimination of Mother-to-Child Transmission of HIV and Congenital Syphilis in the Americas by 2015. This paper aims to describe epidemiological and programmatic characteristics related to maternal and congenital syphilis in selected countries of Latin America and Caribbean for the period 2010-12. The report is based on a multi-country, quantitative and qualitative analysis from data collected from several sources, representing a compilation of country reports from nine countries as part of the 2012 mid-term evaluation of the Strategy. Data was collected based on standardised procedures at country level. Results are variable among countries. All countries have a strategic national plan to eliminate congenital syphilis, with some distinct characteristics for each country. Protocols and guidelines for the management and treatment of maternal and congenital syphilis in all countries were updated between 2011 and 2013. A high rate of missing information for all countries for some indicators was noticed. The main limitation of the analyses is the huge amount of missing data. Countries must continue to be supported to build capacity for collecting high-quality data on intervention coverage and inequities, and to use it as a basis for decisions about how best to reach women and children with interventions. A high level political commitment is necessary to put into practice the Regional Initiative to Eliminate Congenital Syphilis, with the support of Health Ministries.

The aim of this study was to confirm whether the level of lifetime fluoridation exposure is associated with lower dental caries experience in younger adults (15-46 years). Data of the cohort born between 1960 and 1990 residing outside Australia's capital cities from the 2004-2006 Australian National Survey of Adult Oral Health were analysed. Residential history questionnaires were used to determine the percentage of each person's lifetime exposure to fluoridated water (<50%/50+%). Examiners recorded decayed, missing and filled permanent teeth (DMFT). Socio-demographic variables, periodontal risk factors, and access to dental care were included in multivariable least-squares regression models. In bivariate analysis, the higher level of fluoridation category had significantly lower DMFT (mean 6.01 [SE=0.62]) than the lower level of fluoridation group (9.14 [SE=0.73] p<0.01) and lower numbers of filled teeth (4.08 [SE=0.43], 7.06 [SE=0.62], p<0.01). In multivariate analysis, the higher number of full-time equivalent dentists per 100,000 people was associated with a lower mean number of missing teeth (regression coefficient estimate=-1.75, p=0.03), and the higher level of water fluoridation with a lower mean DMFT (-2.45, p<0.01) and mean number of filled teeth (-2.52, p<0.01). The higher level of lifetime fluoridation exposure was associated with substantially lower caries experience in younger rural adults, largely due to a lower number of filled teeth. © 2015 Australian Dental Association.

The aim of our study was to investigate radiographically the prevalence of dental anomalies in a group of Jordanian cleft lip and/or palate subjects. This is a retrospective review of panoramic radiographs of 78 subjects with cleft lip and/or palate that were evaluated from their file records and investigated for possible dental anomalies. Dental anomalies were found frequently in cleft lip and/or palate subjects. Missing teeth were found in 66.7% of the patients; the tooth most commonly missing was the maxillary lateral incisor. Supernumerary teeth were found in 16.7% of patients; 37% had microdontia; 70.5% had taurodontism; 30.8% had transposition and/or ectopic teeth; 19.2% had dilacerations; and 30.8% had hypoplastic teeth. There was no statistically significant difference in the above anomalies' prevalence between males and females. However, it was found that subjects with bilateral cleft lip and/or palate had significantly more microdontia (p = .005), dilaceration (p = .002), and hypoplastic teeth (p = .0001) than subjects with unilateral cleft lip and/or palate. The prevalence of dental anomalies in cleft lip and/or palate patients was higher than what had been reported in the normal Jordanian population. This emphasizes the relation of cleft lip and/or palate to all dental anomalies studied. Although our study represents a thorough and complete description of dental anomalies present in a sample of cleft lip and/or palate subjects, larger samples are required to effectively determine the relationship of each dental anomaly with cleft type.

The aim of the present study was to compare the association of CD4 count with cariogenic oral flora indicators and dental caries in HIV-seropositive children receiving antiretroviral therapy (ART). A descriptive study was conducted among HIV-seropositive children receiving ART at Snehasadan Camillian Care and Support Center HIV/AIDS in Mangaluru, India. Demographic details and r recent CD4 counts were recorded. For dental caries, the Decayed, Missing, Filled Teeth (DMFT)/decayed, missing, filled/decayed, extracted, filled index was used. Data were analyzed using SPSS version 22. Spearman's correlation was used to correlate CD4 count with dental caries and cariogenic oral flora indicators (mutans streptococci and lactobacilli). The study population comprised 35 patients. Dental caries prevalence was 54.1% in deciduous teeth and 41.2% in permanent teeth. Age and DMFT showed a significant, positive correlation; age and dmft showed a negative correlation (P < .05). A weak, negative correlation was found between age and Streptococcus mutans (S. mutans), and also CD4 count; S. mutans and CD4 count and dmft were not found to be statistically significant (P < .05). No statistically-significant correlation was found between CD4 count and cariogenic oral flora indicators in HIV-positive patients. The presence of a minimum number of restored teeth compared to decayed teeth suggests a lack of dental care being given to HIV-positive patients. © 2017 John Wiley & Sons Australia, Ltd.

The objective of this study was to explore oral health-related behavior, how patients with diabetes differ from patients not diagnosed with diabetes in their oral health and whether oral health-related behavior moderates the oral health status of patients with diabetes. Survey and chart review data were collected from 448 patients (52% male, 48% female, average age: 57 years) of which 77 were diagnosed with diabetes (17%). Patients with diabetes had a higher percentage of teeth with mobility than those not diagnosed with diabetes (14% vs. 8%, p=0.023), as well as gingival recession (16% vs. 12%, p=0.035) and more teeth with recession in the esthetic zone (1.17 vs. 0.88, p=0.046). They also had more decayed, missing and filled surfaces due to caries (101 vs. 82, p<0.001) and more missing teeth due to caries (11 vs. 7, p<0.001). Patients with diabetes brushed and flossed less frequently. Patients with diabetes who did not brush regularly had poorer periodontal health (percentage of teeth with probing depth of <4 mm: 82% vs. 60%, p=0.039, 4 to 6 mm: 34% vs. 17%, p=0.059) and more caries (percentage of decayed teeth: 32% vs. 15%, p=0.033) than regularly brushing patients with diabetes. Educating patients with diabetes about the importance of good oral self care needs to become a priority for their oral health care providers.

Objectives: The purpose of this study was to evaluate the short-term dentoalveolar and soft tissue changes in late adolescent patients treated with the Forsus™ FRD. Methods: A prospective study was carried out on 54 lateral cephalometric radiograms that were taken before placement and after removal of the appliance in the treatment group (15 subjects) and at the beginning and six months after in the control group (12 subjects). The patient selection criteria were as follows: skeletal and dental Class II malocclusion due to retrognatic mandible, normal or low-angle growth pattern, post-peak growth period, no extracted or congenitally missing permanent teeth, and minimum crowding in the lower dental arch. Results: The statistical assesment of the data suggested the following results: No sagital and vertical skeletal changes were induced. The mandibular incisors were protruded and intruded, while the maxillary incisors were retruded and extruded. The occlusal plane was rotated in clockwise direction as a result of these dentoalveolar changes. Overbite and overjet were reduced in all patients. Soft tissue profile slightly improved. Conclusions: The results revealed that, in late-adolescent patients Forsus™ FRD corrected Class II discrepancies through maxillary and mandibular dentoalveolar changes. PMID:22589581

The association between prune belly syndrome and dental anomalies: a case report.

PubMed

Basso, Maria Daniela; Favretto, Carla Oliveira; Cunha, Robson Frederico

2012-12-18

Prune belly syndrome is a rare condition produced by an early mesodermal defect that causes abdominal abnormalities. However, the literature indicates that disturbances related to ectodermal development may also be present. This is the first case report in the literature to suggest that dental abnormalities are part of the broad spectrum of clinical features of prune belly syndrome. Because the syndrome causes many serious medical problems, early diagnosis of abnormalities involving the primary and permanent dentitions are encouraged. The authors report the clinical case of a 4-year-old Caucasian boy with prune belly syndrome. In addition to the triad of abdominal muscle deficiency, abnormalities of the gastrointestinal and urinary tracts, and cryptorchidism, a geminated mandibular right central incisor, agenesis of a mandibular permanent left incisor, and congenitally missing primary teeth (namely, the mandibular right and left lateral incisors) were noted. This original case report about prune belly syndrome highlights the possibility that dental abnormalities are a part of the broad spectrum of clinical features of the syndrome. Therefore, an accurate intra-oral clinical examination and radiographic evaluation are required for patients with this syndrome in order to provide an early diagnosis of abnormalities involving the primary and permanent dentitions.

Dentoalveolar development in subjects with normal occlusion. A longitudinal study between the ages of 5 and 31 years.

PubMed

Thilander, Birgit

2009-04-01

The aim of the present study was to examine dentoalveolar development in subjects with an 'ideal' (normal) occlusion. The material comprised 436 study casts of 189 male and 247 female subjects of Swedish origin between the ages of 5 and 31 years with no history of orthodontic treatment. Tooth width, and arch length, width, and depth, as well as palatal height were measured. The data were analysed with a Student's t-test. The results verified that continuous changes of the dental arches occur from the primary until the adult period, with individual variations. This change could be interpreted as a biological migration of the dentition, resulting in anterior crowding especially in the mandible, even in subjects with congenitally missing third molars. The occlusion should be regarded as a dynamic rather than a stable interrelationship between facial structures. This natural development has to be considered in orthodontic treatment planning as well as in assessment of stability following orthodontic treatment. A continuous increase of palatal height up to adulthood seems to be an effect of a slow continuous eruption of the teeth. This finding is also of significance in explaining the infraposition of implant-supported crowns.

Cleft lip and palate surgery in the developing child is known to be associated with maxillary hypoplasia. However, the effects of nonsurgical manipulations on maxillary growth have not been well investigated. The authors present the contribution of orthodontic dental space closure with canine substitution to maxillary hypoplasia and the need for orthognathic surgery. Cleft lip/palate and cleft palate patients older than 15 years of age were reviewed for dental anomalies, orthodontic canine substitution, and Le Fort I advancement. Skeletal relationships of the maxilla to the skull base (SNA), mandible (ANB), and facial height were determined on lateral cephalograms. Logistic regression analyses were performed to estimate odds ratios. Ninety-five patients were reviewed (mean age, 18.1 years). In 65 patients with congenitally missing teeth, 55 percent with patent dental spaces required Le Fort I advancement. In contrast, 89 percent who underwent canine substitution required Le Fort I advancement (p = 0.004). Canine substitution is associated with a statistically significant increase in maxillary retrognathia when compared with dental space preservation on lateral cephalograms (mean SNA, 75.2 and 79.0, respectively; p = 0.006). Adjusting for missing dentition, logistic regression analyses demonstrated that canine substitution is an independent predictor for orthognathic surgery (OR, 6.47) and maxillary retrusion defined by SNA < 78 (OR, 8.100). The coordination of orthodontia and surgery is essential to cleft care. The authors report a strong association between orthodontic cleft closure using canine substitution with maxillary hypoplasia and subsequent Le Fort I advancement, and suggest systematic criteria for management of cleft-related dental agenesis.

Atypical dentofacial structures may be the first indicator of other anomalies linked to a syndrome. This case describes the management of a 9-year-old girl referred for the routine management of supernumerary teeth. The anomalous form of her teeth, together with multiple supernumerary units and a history of congenital cataracts, were suggestive of a diagnosis of Nance-Horan syndrome. This is an X-linked disorder, in which females usually demonstrate mild expression; this case was unusual in respect to the marked phenotype expressed. Unusually, the girl developed 2 spontaneous abscesses of her noncarious upper incisor teeth; a feature never previously described in this syndrome. This report details the patient's dental management and discusses the possible pathogenesis of the dental abscesses, together with the genetic implications of this syndrome.

Supernumerary teeth (ST) are odontostomatologic anomaly characterized by as the existence excessive number of teeth in relation to the normal dental formula. This condition is commonly seen with several congenital genetic disorders such as Gardner's syndrome, cleidocranial dysostosis and cleft lip and palate. Less common syndromes that are associated with ST are; Fabry Disease, Ellis-van Creveld syndrome, Nance-Horan syndrome, Rubinstein-Taybi Syndrome and Trico–Rhino–Phalangeal syndrome. ST can be an important component of a distinctive disorder and an important clue for early diagnosis. Certainly early detecting the abnormalities gives us to make correct management of the patient and also it is important for making well-informed decisions about long-term medical care and treatment. In this review, the genetic syndromes that are related with ST were discussed. PMID:25713500

Nonsyndromic tooth agenesis patterns and associated developmental dental anomalies: a literature review with radiographic illustrations.

Agarwal, P; Vinuth, D P; Dube, G; Dube, P

2013-01-01

Tooth agenesis is one of the most intriguing phenomena, because it is frequently associated with other oral anomalies, structural variations and malformations of other teeth, late eruption, transposition and crowding. The diagnosis can be quite challenging as radiographic examination is critical for the diagnosis but not always possible and the late developing teeth may be sometimes scored developmentally missing. Accurate diagnosis therefore requires radiographic, clinical, and dental cast examinations. It is an important clinical and public health problem. Patients with missing permanent teeth may suffer from a reduced chewing ability, inarticulate pronunciation, and an unfavorable aesthetic appearance. Clinically, early diagnosis of a dental anomaly can alert the clinician to the possible development of other associated dental anomalies in the same patient or family, and avoid the possible sequelae. Understanding of tooth agenesis patterns and their impact on diagnosis, prevention, and eventually therapeutics are becoming integral parts of comprehensive dental care. Dental examination with radiographic screening of hypodontia in early childhood should be emphasized as part of public oral health policy to allow early diagnosis and timely intervention.

A blue roan Percheron foal was born with poorly circumscribed patchy alopecia of the trunk and legs. Teeth and hoof development were normal. Alopecia was progressive, becoming almost complete by 1 year of age. Histopathological findings in a skin biopsy obtained at 7 months of age were consistent with severe follicular hypoplasia. Sebaceous glands, epitrichial sweat glands and arrector pilae muscles were normal. The horse is alive and otherwise well at 6 years of age, although adult stature is considered small for this breed. The clinical history and histopathological findings are most consistent with a form of congenital hypotrichosis.

In pediatric patients, the overlay dentures establish a relatively stable occlusion that improves patient's tolerance to the future treatment procedures for worn dentition. This clinical report highlights the imperative need of appropriate treatment strategy and application of maxillary and mandibular overlay dentures in a pediatric patient who suffered from congenitally mutilated and worn dentition.

Amelogenesis imperfecta (AI) is a tooth disorder characterized by the abnormal development of the enamel in response to mutations in the genes involved in amelogenesis. The objective of this article is to present the clinical case of a child with AI in the primary dentition phase. A 4-year-old boy was presented to a clinic by his mother, who complained that her son's smile esthetics were compromised by "weak and yellow teeth." All the teeth showed yellowish discoloration as well as crumbling or missing enamel. Due to the absence of carious lesions and the presence of normal pulp in the teeth, it was decided to restore the dentition with indirect crowns of ceramic-optimized polymer, also known as ceromer. No preparations were performed on the teeth. For this patient, indirect ceromer restorations presented a good treatment option for the rehabilitation of primary teeth affected by AI.

Today, and looking to the future, scientific discoveries from cellular, developmental and molecular biology inform our understanding of cell, tissue and organ morphogenesis as exemplified in skin, bone, cartilage, dentine, enamel, muscle, nerve and many organs such as salivary glands and teeth. Present day biomedical science yields principles for the biomimetic design and fabrication of cells, tissues and organs. Bioengineering has become a strategy that can 'mimic' biological processes, and inform clinical procedures for tissue and organ replacements. The future of regenerative craniofacial biology holds enormous promise for the diagnosis and treatment of congenital birth defects, traumatic injuries, degenerative chronic diseases as well as for Mendelian single gene and complex multigene diseases and disorders. The past 50 years have heralded the completion of the human genome and the introduction of 'personalized medicine and dentistry', the utilization of stem cell therapy for an array of diseases and disorders, the 'proof of principle' to reverse select inherited diseases such as anhidrotic ectodermal dysplasia (ED), and the fruits from interdisciplinary research drawn from the diverse biomedical sciences. Looking to the future, we can readily anticipate as major goals to emphasize the clinician's role in identifying clinical phenotypes that can lead to differential diagnosis, and rejuvenate missing or damaged tissues by establishing processes for the utilization of gene, cell and/or protein therapies. The future is replete with remarkable opportunities to enhance clinical outcomes for congenital as well as acquired craniofacial malformations. Clinicians play a pivotal role because critical thinking and sound clinical acumen substantially improve diagnostic precision and thereby clinical health outcomes. © 2014 Australian Dental Association.

Autoextraction of twelve permanent teeth in a child with autistic spectrum disorder.

2016-03-01

This report discusses self-injurious behaviour; this is not unusual in people with autistic spectrum disorders but is not commonly experienced as autoextraction. This case concerns a 12 year old child who presented as a new patient with two teeth missing. He then went on to remove a further ten teeth over a relatively short space of time. The recognition of autoextraction by the dental team is important. its management involves a multidisciplinary team which includes professionals from education, health and social care who work together to prevent progressive self-injury. © 2015 BSPD, IAPD and John Wiley & Sons A/S.

Reconstruction-Based Digital Dental Occlusion of the Partially Edentulous Dentition.

PubMed

Zhang, Jian; Xia, James J; Li, Jianfu; Zhou, Xiaobo

2017-01-01

Partially edentulous dentition presents a challenging problem for the surgical planning of digital dental occlusion in the field of craniomaxillofacial surgery because of the incorrect maxillomandibular distance caused by missing teeth. We propose an innovative approach called Dental Reconstruction with Symmetrical Teeth (DRST) to achieve accurate dental occlusion for the partially edentulous cases. In this DRST approach, the rigid transformation between two symmetrical teeth existing on the left and right dental model is estimated through probabilistic point registration by matching the two shapes. With the estimated transformation, the partially edentulous space can be virtually filled with the teeth in its symmetrical position. Dental alignment is performed by digital dental occlusion reestablishment algorithm with the reconstructed complete dental model. Satisfactory reconstruction and occlusion results are demonstrated with the synthetic and real partially edentulous models.

The purpose of this retrospective cohort study was to evaluate the incidence of missed canals in endodontically treated teeth in the Greater Philadelphia area patient population and to evaluate the effect of untreated canals on endodontic outcome. A total of 1397 cone-beam computed tomography (CBCT) volumes taken from January 2013 to July 2015 were investigated. Limited view CBCT images were taken with Kodak 9000 3D System field of view at voxel size, 76 μm or Morita Veraviewpocs 3D F40 field of view at voxel size, 125 μm. All root canal-treated premolars and molars were included in the study. Unfilled canals appearing from cementoenamel junction to apex including splitting from a main canal at coronal, mid, or apical third were defined as missed-untreated canal. A periapical lesion was diagnosed when disruption of the lamina dura was detected and the low density area associated with the radiographic apex was at least twice the width of the periodontal ligament space. The overall incidence of missed canals was 23.04%. The incidence of missed canals per tooth was highest in tooth #14 at 46.5% and tooth #3 at 41.3%. The incidence of missed canals was highest in the upper molars at 40.1% and lowest in the upper premolars at 9.5%. There was a significant difference in lesion prevalence when a canal was missed-untreated (P < .05). Teeth with a missed canal were 4.38 times more likely to be associated with a lesion. Limited field-of-view CBCT should be examined before any endodontic retreatment to identify missed canals. This knowledge would not only help clinicians to locate missed canals clinically but would also help in deciding the surgical approach. Copyright © 2016 American Association of Endodontists.

This study was aimed at investigating the caries status of Chinese civilian pilots and the relationship between caries and oral health behaviors, including sugar intake, smoking, alcohol consumption, tooth brushing, and dental check-up attendance. This cross-sectional investigation enrolled pilots from Shenzhen Airline. A questionnaire was used to collect general information and oral health behaviors. The Decayed, Missing, and Filled Teeth (DMFT) Index, International Caries Detection and Assessment System (ICDAS) II, caries prevalence, and rate of missing teeth were recorded via oral examination. Rank correlation was used to reveal the correlation between caries and oral health behavior. All of the pilots were men ages 21-58 yr (mean, 31.48 ± 7.20). In the caries group (CG), the frequency of tooth brushing and flossing was a little higher; more subjects had already given up smoking; more subjects had higher alcohol consumption; the sugar intake index (SII) was a little bit higher; and the last dental attendance time (LDAT) was shorter than that in the noncaries group (NCG). A total of 211 pilots (37.95%) had caries and 85 (15.29%) had missing teeth. The average DMFT was 2.19, while the mean ICDAS was 0.72. The frequency of sugary beverage consumption was negatively correlated with caries (r = -0.088), while a positive relationship was found between LDAT and caries (r = 0.094). Chinese civilian pilots have relatively good oral hygiene behavior and dental health. A relationship was found between sugary beverage consumption/LDAT and caries.

Ectodermal dysplasia (ED) syndrome comprises a large, heterogeneous group of inherited disorders that are defined by primary defects in the development of 2 or more tissues derived from the embryonic ectoderm. The tissues primarily involved are the skin and its appendages (including hair follicles, eccrine glands, sebaceous glands, nails) and teeth. The clinical features include sparse hair, abnormal or missing teeth, and an inability to sweat due to lack of sweat glands. One such case report of ectodermal dysplasia is presented here.

To evaluate the role of inhibitory substances produced by bacteria in the oral cavity, we estimated, by a deferred test on Todd-Hewitt agar enriched with hemin and vitamin K, the proportion of bacteria that inhibited or stimulated the growth of Streptococcus mutans and Porphyromonas gingivalis, from the saliva of 109 patients (54 males and 55 females) attending our dental clinics. The patients, aged from 8 to 75 years old (mean: 31 +/- 18 years), were randomly selected whatever the reason for their visit. The results, evaluated with the Spearman rank test, indicated that there was no statistically significant (P > 0.05) correlation between the proportion of salivary bacteria inhibiting or stimulating P. gingivalis with the Community Periodontal Index of Treatment Needs (CPITN), the number of carious, missing and filled teeth, or with the decayed, missing and filled teeth index (DMFT). Also, no statistically significant correlation was observed between the proportion of salivary bacteria stimulating the growth of S. mutans and the above mentioned health indexes. However, a statistically significant (P < 0.005) negative correlation was found between the percentage of cultivated bacteria that inhibit S. mutans and the percentage of untreated carious teeth as well as with the CPITN. The results thus indicate a possible role for inhibitory substances produced by bacteria in the maintenance of oral health.

ABSTRACT Objective To identify the prevalence of the main oral problems present in special needs children and to relate the underlying conditions with the clinical and demographic variables. Methods The study was based on the physical examination of 47 students from the Associação de Pais e Amigos dos Excepcionais diagnosed as Down syndrome, cerebral palsy and intellectual deficit. For data collection, we used a self-administered questionnaire that included indices of dental caries and oral hygiene, Angle classification, malposition of dental groups and oral hygiene habits. Results The predominant age group was 12-25 years (46.8%) and most patients were male (55.3%). Regarding daily brushing, 63.8% reported brushing their teeth three times a day, and 85.1% did it by themselves. A total of 48.9% were rated as Angle class I, and 25.5% had no type of malocclusion. A high dental carries index (decayed, missing, filled >10) was observed in 44.7%, and 53.2% had inadequate oral hygiene (zero to 1.16). There was a statistically significant difference between cerebral palsy and the act of the participants brushing their teeth by themselves. Conclusion There was a high decayed-missing-filled teeth index and malocclusion class I, as well as inadequate oral hygiene. The type of underlying condition of the participants influenced the act of brushing teeth by themselves. PMID:28076597

Abnormal primary and permanent dentitions with ectodermal symptoms predict WNT10A deficiency.

PubMed

2016-11-24

The WNT10A protein is critical for the development of ectodermal appendages. Variants in the WNT10A gene may be associated with a spectrum of ectodermal abnormalities including extensive tooth agenesis. In seven patients with severe tooth agenesis we identified anomalies in primary dentition and additional ectodermal symptoms, and assessed WNT10A mutations by genetic analysis. Investigation of primary dentition revealed peg-shaped crowns of primary mandibular incisors and three individuals had agenesis of at least two primary teeth. The permanent dentition was severely affected in all individuals with a mean of 21 missing teeth. Primary teeth were most often present in positions were succedaneous teeth were missing. Furthermore, most existing molars had taurodontism. Light, brittle or coarse hair was reported in all seven individuals, hyperhidrosis of palms and soles in six individuals and nail anomalies in two individuals. The anomalies in primary dentition preceded most of the additional ectodermal symptoms. Genetic analysis revealed that all seven individuals were homozygous or compound heterozygous for WNT10A mutations resulting in C107X, E222X and F228I. We conclude that tooth agenesis and/or peg-shaped crowns of primary mandibular incisors, severe oligodontia of permanent dentition as well as ectodermal symptoms of varying severity may be predictors of bi-allelic WNT10A mutations of importance for diagnosis, counselling and follow-up.

Previous studies focused on the dental caries status of East African children and not on their overall dental needs. Urban children consume more sugar-rich foods. To assess overall dental treatment needs of children living in an orphanage in Uganda. Teeth were diagnosed as needing treatment by obvious frank carious lesions (WHO criteria), temporary fillings, staining, or very deep pit and/or fissures possibly requiring sealants. Calculus or crowding in the mandibular anterior region and evidence of tooth fractures were recorded, as were signs of wear on the mandibular molars and canines and the maxillary incisors. Most of the primary teeth (64%) required no dental treatment, but almost all (98%) of the permanent teeth did. A mean (±standard deviation) of 4.81±1.92 permanent teeth required treatment. The mean number of missing teeth was 0.47. Thirty-one children (20.2%) had crowding, 52 (34%) had calculus, and 49 (32%) had signs of attrition on primary and permanent molar teeth (45 enamel only and 4 enamel and dentin). Most of the primary teeth required no dental treatment, while the vast majority of permanent teeth did, possibly in association with high sugar cane consumption and poor brushing habits among older children.

Congenital hypogonadotropic hypogonadism: implications of absent mini-puberty.

PubMed

Dwyer, Andrew A; Jayasena, Channa N; Quinton, Richard

2016-06-01

The phenomenon known as "mini-puberty" refers to activation of the neonatal hypothalamo-pituitary axis causing serum concentrations of gonadotrophins and testosterone (T) to approach adult male levels. This early neonatal period is a key proliferative window for testicular germ cells and immature Sertoli cells. Although failure to spontaneously initiate (adolescent) puberty is the most evident consequence of a defective gonadotropin-releasing hormone (GnRH) neurosecretory network, absent mini-puberty is also likely to have a major impact on the reproductive phenotype of men with congenital hypogonadotrophic hypogonadism (CHH). Furthermore, the phase of male mini-puberty represents a key window-of-opportunity to identify congenital GnRH deficiency (either isolated CHH, or as part of combined pituitary hormone deficiency) in childhood. Among male neonates exhibiting "red flag" indicators for CHH (i.e. maldescended testes with or without cryptorchidism) a single serum sample (between 4-8 weeks of life) can pinpoint congenital GnRH deficiency far more rapidly and with much greater accuracy than dynamic tests performed in later childhood or adolescence. Potential consequences for missing absent mini-puberty in a male neonate include the lack of monitoring of pubertal progression/lack of progression, and the missed opportunity for early therapeutic intervention. This article will review our current understanding of the mechanisms and clinical consequences of mini-puberty. Furthermore, evidence for the optimal clinical management of patients with absent mini-puberty will be discussed.

The aim of this study was to determine the dental health status and treatment needs of personnel in the Infantry Regiment of the Malaysian Territorial Army (TA).This cross-sectional study involved stratified and systematic random sampling with a total sample size of 300. Dental health status and treatment needs were assessed using the standard WHO oral assessment criteria (1997). The prevalence of caries experience was 96% (mean ± SD DMFT [decayed, missing, filled teeth] = 8.0 ± 5.5). Active decay prevalence was high (85%; mean ± SD = 3.6 ± 3.1) indicating high unmet treatment need. Missing teeth prevalence was high (69%; mean ± SD = 2.8 ± 3.7). Filled teeth prevalence was low (56%, mean ± SD = 1.5 ± 2.0). In all, 90% of participants required some form of dental treatment, of whom 85% required restorative treatment, 5% advanced restorative treatment, 36.7% extractions, and 45.3% prosthetic treatment. These findings suggest that there was a high need for dental treatment in the Infantry Battalions of Malaysian TA Regiments and the service must be made available to cater to the needs.

When a maxillary lateral incisor is missing, often the treatment options can be clearly defined, that is, substitute an adjacent tooth for the missing one; open the space for an implant, a bonded bridge or fixed bridge. When a maxillary central incisor is missing and the space for the tooth is absent, the treatment choices become complicated, especially in a growing child. There must be multi-disciplinary coordination among the restorative dentist, the oral surgeon or periodontist, and the orthodontist to obtain the optimum result. At the initiation of treatment, this information must be relayed and the treatment plan agreed upon by the patient or the parents of the patient.

A dental wax was evaluated after unilateral application in 20 client-owned, mixed and purebred small dogs using a clean, split-mouth study model. All dogs had clinical signs of periodontal disease including plaque, calculus, and/or gingivitis. The wax was randomly applied to the teeth of one side of the mouth daily for 30-days while the contralateral side received no treatment. Owner parameters evaluated included compliance and a subjective assessment of ease of wax application. Gingivitis, plaque and calculus accumulation were scored at the end of the study period. Owners considered the wax easy to apply in all dogs. Compliance with no missed application days was achieved in 8 dogs. The number of missed application days had no effect on wax efficacy. There was no significant difference in gingivitis or plaque accumulation scores when comparing treated and untreated sides. Calculus accumulation scores were significantly less (22.1 %) for teeth receiving the dental wax.

Over 5% of the world's population has disabling hearing loss. The oral health of the disabled may be disused for the reason of the disabling condition, a challenging disease or the limited access to oral health care. The objectives of the study were to assess the prevalence of dental caries and periodontal status of institutionalized hearing impaired (HI) children in Khordha district of Odisha. A descriptive cross-sectional study on the HI children was conducted in Khordha district, Odisha. Type III examination procedure was conducted to assess the oral health status of the children. Statistical analysis was performed by Chi-square test and Student's t-test, and the significance level was fixed at P < 0.05. The final population consisted of 540 HI children out of which 262 (48.5%) were male and 278 (51.5%) were female, 285 (52.8%) children had severe hearing loss and 227 (42.0%) had profound hearing loss. Bleeding on probing was found in 72 (13.3%) female children as compared to 57 (10.6%) male children. While 131 (24.3%) female children had calculus, 124 (23.0%) male children had the same condition. Total caries prevalence was 19.3%. Statistically highly significant difference was found for mean decayed teeth (DT), missing teeth decayed, missing filled teeth (FT) (P < 0.001), while for mean FT there was no statistically significant difference according to age groups. Statistically highly significant difference was found for mean DT, extracted teeth and decayed, extracted, filled teeth (P < 0.001). An improved accessibility to dental services as well as dental health education is necessary to ensure the optimum dental health within the reach of these less fortunate children.

Geometric Evaluation of the Effect of Prosthetic Rehabilitation on Facial Asymmetry in Patients with Unilateral Maxillectomy.

Aswehlee, Amel M; Hattori, Mariko; Elbashti, Mahmoud E; Sumita, Yuka I; Taniguchi, Hisashi

This study aimed (1) to geometrically evaluate areas of facial asymmetry in patients with two different types of maxillectomy defect compared to a control group, (2) to geometrically evaluate the effect of an obturator prosthesis on facial asymmetry, and (3) to investigate the correlation between three-dimensional (3D) deviation values and number of missing teeth. Facial data from 13 normal control participants and 26 participants with two types of maxillectomy defect (groups 1 and 2) were acquired with a noncontact 3D digitizer. Facial asymmetry was evaluated by superimposing a facial scan onto its mirror scan using 3D evaluation software. Facial scans with and without obturator prostheses were also superimposed to evaluate the obturator effect. The correlation between 3D deviation values and number of missing teeth was also evaluated. Statistical analyses were performed. Facial asymmetry was significantly different between the control group and each maxillectomy defect group (group 1: P < .0001 and P = .020 without and with obturator, respectively; group 2: P < .0001 for both conditions). There were no significant differences in asymmetry between groups 1 and 2 either without or with obturator (P = .457 and P = .980, respectively). There was a significant difference in the obturator effect between groups 1 and 2 (P = .038). 3D deviation values were positively correlated with number of missing teeth in group 1 (r = 0.594, P = .032), but not in group 2. A noncontact 3D digitizer and 3D deviation assessment were effective for analyzing facial data of maxillectomy patients. Obturators were effective for improving facial deformities in these patients.

To describe the orthodontic treatment of a nongrowing 30-year-old woman with asymmetric severe skeletal Class II malocclusions (asymmetric Angle Class II), large overjet (16 mm), large overbite (8 mm), two congenitally missing mandibular incisors (presenting a deciduous anterior tooth), and signs and symptoms of temporomandibular joint disorder (TMD). We used novel improved super-elastic Ni-Ti alloy wires (ISWs) combined with Ni-Ti alloy coil springs, power hooks, and a zygomatic implant as reinforced anchorage to provide a constant and continuous mild force to the dentition. We successfully distalized maxillary molars, premolars, and retracted anterior teeth and corrected the asymmetric Angle Class II molar relationship using this system of zygomatic anchorage in conjunction with ISWs, Ni-Ti alloy open-coil springs, and crimpable power hook. The maxillary molars were distalized, and postero-occlusal relationships were improved to achieve Class I canine and molar relationships on both sides. Intrusion of the upper molars made the mandibular plane close. Ideal overbite and overjet relationships were established. Facial esthetics were improved with decreased upper and lower lip protrusion, and no symptoms of TMD were observed after treatment. The orthodontic treatment described here is a promising anchorage technique alternative to traditional techniques to improve severe skeletal Class II with TMD.

The association between prune belly syndrome and dental anomalies: a case report

PubMed Central

2012-01-01

Background Prune belly syndrome is a rare condition produced by an early mesodermal defect that causes abdominal abnormalities. However, the literature indicates that disturbances related to ectodermal development may also be present. This is the first case report in the literature to suggest that dental abnormalities are part of the broad spectrum of clinical features of prune belly syndrome. Because the syndrome causes many serious medical problems, early diagnosis of abnormalities involving the primary and permanent dentitions are encouraged. Case presentation The authors report the clinical case of a 4-year-old Caucasian boy with prune belly syndrome. In addition to the triad of abdominal muscle deficiency, abnormalities of the gastrointestinal and urinary tracts, and cryptorchidism, a geminated mandibular right central incisor, agenesis of a mandibular permanent left incisor, and congenitally missing primary teeth (namely, the mandibular right and left lateral incisors) were noted. Conclusion This original case report about prune belly syndrome highlights the possibility that dental abnormalities are a part of the broad spectrum of clinical features of the syndrome. Therefore, an accurate intra-oral clinical examination and radiographic evaluation are required for patients with this syndrome in order to provide an early diagnosis of abnormalities involving the primary and permanent dentitions.

Use of mini dental implants in ectodermal dysplasia children: follow-up of three cases.

PubMed

Sfeir, E; Nassif, N; Moukarzel, C

2014-07-01

Ectodermal dysplasia is a hereditary genodermatosis characterised by a congenital defect of ectodermal structures, causing tooth malformations and anomalies. Implantology has become accepted in these subjects. However cases are often complicated by a reduction in the size of the alveolar process, making the insertion of conventional implants difficult without bone grafting. The reduced diameter of mini-implants and their ease of insertion provide an interesting solution in supporting removable or fixed prosthesis. The purpose of this paper is to report the follow-up of three cases of children (11-12 year- old) with ectodermal dysplasia in which mini-implants were used to support the prostheses. In the first case, two mini-implants were inserted into the anterior part of the mandible for stabilising a removable denture (2 years follow-up). In the other two cases, mini- implants were inserted in the maxilla and mandible to replace missing front teeth with fixed prostheses. Patients were called for follow- up every 6 months: in the sencod case follow-up lasted 4 years in the mandible and 2 years in the maxilla; in the third case, 2 years in the maxilla and 1 year in the mandible. The use of mini-implants in children with ectodermal dysplasia can enhance aesthetics, and functional and psychosocial development.

To assess the knowledge of dental decay among pregnant women and its relationship with sociodemographic characteristics and caries experience in rural India. A cross-sectional study was conducted among 381 pregnant women in southern India. Variables and knowledge of dental decay were recorded using a structured self-administered questionnaire. Dental caries was recorded by a calibrated examiner as per WHO guidelines. The majority of the respondents were under 30 years of age (91.6%), utilised a public health-care delivery system (57.2%), were primigravid (63%), had a pre-universtiy diploma (64.8%) and were in the 3rd trimester (63%). Overall, poor knowledge was expressed by 12% to 37% of the women. The mean (±SD) DT (decayed teeth), MT (missing teeth), FT (filled teeth) and DMFT (decayed, missing and filled teeth) were 3.08 (±2.6), 0.93 (±2.23), 0.39 (±1.14) and 4.4 (±3.56), respectively. There were no significant differences in the responses to the knowledge of caries with respect to age and trimester. Educational status, health-care delivery system and number of pregnancies had a significant association with knowledge of caries. This study highlighted the limited knowledge of dental decay among pregnant, rural, southern Indian women. Preventive programmes for pregnant women should be designed based upon a thorough interview including an informative session on the specific risks during this period, in order to motivate the patient towards oral health and implement the needed prophylactic measures.

The Hispanic and Latino population is projected to increase from 16.7 percent to 30.0 percent by 2050. Previous U.S. national surveys had minimal representation of Hispanic and Latino participants other than Mexicans, despite evidence suggesting that Hispanic or Latino country of origin and degree of acculturation influence health outcomes in this population. In this article, the authors describe the prevalence and mean number of cavitated, decayed and filled surfaces, missing teeth and edentulism among Hispanics and Latinos of different national origins. Investigators in the Hispanic Community Health Study/Study of Latinos (HCHS/SOL)-a multicenter epidemiologic study funded by the National Heart, Lung, and Blood Institute with funds transferred from six other institutes, including the National Institute of Dental and Craniofacial Research-conducted in-person examinations and interviews with more than 16,000 participants aged 18 to 74 years in four U.S. cities between March 2008 and June 2011. The investigators identified missing, filled and decayed teeth according to a modified version of methods used in the National Health and Nutrition Examination Survey. The authors computed prevalence estimates (weighted percentages), weighted means and standard errors for measures. The prevalence of decayed surfaces ranged from 20.2 percent to 35.5 percent, depending on Hispanic or Latino background, whereas the prevalence of decayed and filled surfaces ranged from 82.7 percent to 87.0 percent, indicating substantial amounts of dental treatment. The prevalence of missing teeth ranged from 49.8 percent to 63.8 percent and differed according to Hispanic or Latino background. Significant differences in the mean number of decayed surfaces, decayed or filled surfaces and missing teeth according to Hispanic and Latino background existed within each of the age groups and between women and men. Oral health status differs according to Hispanic or Latino background, even with adjustment for age, sex and other characteristics. These data indicate that Hispanics and Latinos in the United States receive restorative dental treatment and that practitioners should consider the association between Hispanic or Latino origin and oral health status. This could mean that dental practices in areas dominated by patients from a single Hispanic or Latino background can anticipate a practice based on a specific pattern of treatment needs.

Fanconi's anaemia (FA) is a rare, inherited autosomal recessive genetic disease characterized by progressive bone marrow failure, congenital abnormalities, and high predisposition to malignancies. The incidence of the disease is unusually high in the Afrikaner population of South Africa with calculated heterozygote prevalence being approximately 1 in 77. This report describes the oral clinical and radiological findings in a 16 year old male with FA. Medical and dental history was noted, the oral mucosa was examined and the teeth were screened for fillings and caries. Periodontal examination consisted of: measurement of probing depths, recession, mobility of teeth, furcation involvement, plaque index and gingival index. An orthopantomograph was taken. There was a generalized black hyper-pigmentation on the buccal mucosa, tongue and palate. The patient had generalized gingival recession and most of the periodontal pockets were deeper than 5mm. Several teeth were mobile and the orthopantomograph showed loss of alveolar bone in the furcation areas of most posterior teeth. A diagnosis of severe generalized periodontitis associated with systemic disease was made. Patients with Fanconi's anaemia are susceptible to severe dental and periodontal diseases.

Dental diseases are among the most frequently reported health problems in drug abusers. However, few studies have been conducted on oral health of methamphetamine (meth) abusers in China. The aim of the present study was to investigate the caries and periodontal health profile of former meth abusers in Eastern China. A cross-sectional study was conducted on 162 former meth abusers in the male Zhoushan Compulsory Detoxification Center. A standardized questionnaire, which collected information about age, drug-use duration / pattern, oral hygiene habit and systemic diseases, was administered. Then, a dental examination was performed to investigate the severity of dental caries and periodontal diseases. In evaluating dental caries, the prevalence of dental caries, the scores of decayed teeth (DT), missing teeth (MT), filled teeth (FT), and decayed, missing, filled teeth (DMFT) were recorded. In evaluating periodontal diseases, community periodontal index (CPI), and the prevalence of gingival bleeding, dental calculus, periodontal pocket and loose teeth, were recorded. Additionally, the non-parametric test was adopted to analyze the potential risk factors via SPSS. All the participants abused meth by inhalation. The mean scores of DT, MT, FT and DMFT in the former meth users were 2.72 ± 2.78, 3.07 ± 3.94, 0.33 ± 1.03 and 6.13 ± 5.20 respectively. The prevalence of gingival bleeding, dental calculus, periodontal pocket and loose teeth was 97.53%, 95.68%, 51.23% and 9.26% respectively. The DT, DMFT and CPI scores in those who had abused meth for longer than 4 years were significantly higher than those who abused for less than 4 years (P = 0.039, 0.045, P < 0.001, respectively). The DT score in those who brushed their teeth more than twice a day were significantly lower than those who brushed less (P = 0.018). The status of caries and periodontal diseases among former male meth users in Eastern China was poor. Prolonged drug abuse and lower frequency of tooth brushing may be the risk factors of their poor status of caries and periodontal diseases.

To analyze occlusal changes occurring between the ages of 8 and 65 years in persons with anterior and/or posterior crossbite at the age of 8; to examine their attitudes toward dental appearance and their experiences related to their own teeth. Of the 81 people we contacted who had been documented as having crossbite as 8-year-olds in 1950, 21 agreed to participate in this follow-up study. Their occlusal conditions had been documented initially by intraoral photographs in 1950, and a clinical examination including facial photographs, further occlusal photographs and an interview took place in 2007. For comparison, we also had available similarly-documented examples of individuals (n = 18) of the same age and with normal occlusion in 1950. Oral hygiene was good or excellent in all individuals and all but one visited their dentist regularly. The average number of missing teeth was 3.8, whereas in the normal occlusion sample that number was 1.6. Of the eight persons who had undergone minor orthodontic treatment during childhood, five had an anterior crossbite resolved. Four persons who had initially presented a posterior crossbite later developed an anterior crossbite as well. In 2007, eleven individuals had a posterior and eight an anterior crossbite. At 65, four persons remembered that they had been teased in childhood because of their teeth, and could still remember the terms that had been used. Eighteen persons were satisfied with their teeth although two had severe anterior crossbite; three were dissatisfied, and their reasons were general health problems, mild crowding, and dentofacial asymmetry. Seven persons had TMJ symptoms with various types of history. With three exceptions, they all considered good tooth position to be important or very important. In those not orthodontically treated, malocclusion tended to worsen, although 18 of the 21 persons expressed satisfaction with their teeth as adults. They had a higher average number of missing teeth, and more had TMJ problems than the control group with normal occlusion.

The first part of this review focuses on the anatomy and physiology of the rabbit mouth. Practical understanding is critical to comprehend the dynamic pathologic changes of dental disease, which is one of the most common presenting problems in rabbits. The major theories of the etiopathogenesis of dental disease are presented. The second part focuses on non-dental oral disorders, which encompass only a small incidence of stomatognathic diseases when compared with dental disease. These diseases are primarily composed of infections (treponematosis, oral papillomatosis), neoplasia (frequently involving calcified tissue proliferation), and congenital abnormalities (mandibular prognathism, absent peg teeth, supernumerary peg teeth).

Screening for critical congenital heart disease (CCHD) using pulse oximetry has been endorsed by the American Academy of Pediatrics and the American Heart Association. We sought to determine the incidence of undetected CCHD in Tennessee and the diagnostic gap of CCHD in Middle Tennessee prior to screening implementation. The Tennessee Initiative for Perinatal Quality Care (TIPQC) Undetected CCHD Registry is a quality improvement initiative established to identify neonates discharged from the nursery with undetected CCHD. The TIPQC database was queried and a simultaneous review of all neonates with CCHD in the Middle Tennessee region was performed to define the incidence and identify the pre-screen diagnostic gap of undetected CCHD at the time of hospital discharge. In 2011, of 79,462 live births in Tennessee, 12 newborns had undiagnosed CCHD (incidence 15 per 100,000; 95 % CI 9-26 per 100,000). Nine of 12 (75 %) had coarctation of the aorta (CoA). There were no deaths due to undiagnosed CCHD. In the Middle Tennessee region, 6 of 45 neonates with CCHD were missed, for a diagnostic gap of 13 % (95 % CI 6-26 %). Prior to implementation of CCHD screening using pulse oximetry, 12 Tennessee neonates with CCHD were missed by prenatal ultrasound and newborn examination. CoA was the most common lesion missed and is also the CCHD most likely to be missed despite addition of screening using pulse oximetry. Continued evaluation of the diagnostic gap with particular attention to missed diagnoses of CoA should accompany institution of CCHD screening programs.

Background Two reports by the U.S. surgeon general noted the disproportionate impact of oral disease on and lack of oral health information regarding people with disabilities. Methods In this retrospective study, the authors used clinical and demographic data (from April 1, 2009, through March 31, 2010) from electronic dental records of 4,732 adults with intellectual and developmental disabilities (IDDs) who were receiving dental care through a state-supported system of dental clinics. The authors used these data to investigate the oral health status of, and associated risk factors for, adults with IDD. Results The prevalence of untreated caries in the study population was 32.2 percent, of periodontitis was 80.3 percent and of edentulism was 10.9 percent. The mean (standard deviation) numbers of decayed teeth; missing teeth; and decayed, missing and filled teeth were 1.0 (2.2), 6.7 (7.0) and 13.9 (7.7), respectively. Conclusions Management of oral health presents significant challenges in adults with IDD. Age, ability to cooperate with dental treatment and type of residence are important considerations in identifying preventive strategies. Clinical Implications The study population demonstrated a high burden of dental disease. Further research is required to identify effective interventions to improve oral health in adults with IDD.

To assess the oral health status and treatment needs of an ambulant population of older adults, living in the Maule Region, Chile, and provide descriptive information on its distribution by selected socio-demographic characteristics. The source of primary data was the Regional Oral Health Survey. A stratified random sample of 438 older adults, aged 65-74 years, living independently in the community was orally examined, and underwent an oral health interview. The sample was largely a dentate one (74.9%); with a mean DMFT score of 25.7 (s.d. 6.5) and an average number of missing teeth of 22.4 (s.d. 5.8). Dentate participants had 41% of their restorative care needs unmet, and 68.4% needed oral hygiene instruction plus removal of calculus on their teeth. Almost 30.1% required complex periodontal therapy. 21% of those fully edentulous were in need of full dentures. Comparing these findings with existing data on the oral health of older adults in Chile, participants in this study appear to have lower missing teeth scores and less need for complex periodontal treatment. Inequities were apparent in the proportion of unmet restorative and prosthetics needs. Community-based preventive care programs specifically tailored to older adults are needed to address this challenge. Copyright © 2014 Elsevier Ireland Ltd. All rights reserved.

In a cross-sectional study, we investigated the relationship of Mini-Nutrition Assessment (MNA) results with chewing ability tests and oral examinations (number of teeth present and functional tooth units (FTUs)). The participants were 612 older people (Mean [SD] age: 68.8 [5.9]). According to the MNA score, 25.1% of participants were categorized as having normal nutrition, 67.2% were categorized as at risk of malnourishment, and 7.7% were categorized as having malnutrition. The mean numbers of teeth present and FTUs were [15.5] and [8.9], respectively. The ANCOVA analyses adjusted for age and gender showed that participants with malnutrition had lower numbers of teeth present (8.8), FTUs (8.4), and chewing ability (6.8) than those with normal nutrition (13.3, 10.4 and 7.8) (p < 0.05). Nutritional status was associated with mean numbers of teeth present, FTUs, and chewing ability. Therefore, it was concluded that retention of natural teeth with appropriate numbers of FTUs by replacing missing teeth with dentures and improving chewing ability will help the reduce risk of malnutrition in older adults.

Congenital blindness improves semantic and episodic memory.

PubMed

Pasqualotto, Achille; Lam, Jade S Y; Proulx, Michael J

2013-05-01

Previous studies reported that congenitally blind people possess superior verb-generation skills. Here we tested the impact of blindness on capacity and the fidelity of semantic memory by using a false memory paradigm. In the Deese-Roediger-McDermott paradigm, participants study lists of words that are all semantically related to a lure that is not presented. Subsequently, participants frequently recall the missing lure. We found that congenitally blind participants have enhanced memory performance for recalling the presented words and reduced false memories for the lure. The dissociation of memory capacity and fidelity provides further evidence for enhanced verbal ability in the blind, supported by their broader structural and functional brain reorganisation.

To establish the etiology of heart failure in patients with congenital heart disease can be challenging. Multiple concomitant anomalies that can be missed after an initial diagnosis could be seen in these patients. In patients with congenital heart disease, a more accurate evaluation of cardiac morphology and left ventricular systolic function could be evaluated by recent non-invasive cardiac imaging techniques. We present a rare case where multimodal cardiac imaging was useful to establish the final diagnosis of left ventricular non-compaction associated with Ebstein's anomaly.

The purpose of this study is to examine the associations among depression, anxiety, use of oral health services, and tooth loss. Data were analysed for 80 486 noninstitutionalized adults in 16 states who participated in the 2008 Behavioral Risk Factor Surveillance System. Binomial and multinomial logistic regression analyses were used to estimate predicted marginals, adjusted prevalence ratios, adjusted odds ratios (AOR) and their 95% confidence intervals (CI). The unadjusted prevalence for use of oral health services in the past year was 73.1% [standard error (SE), 0.3%]. The unadjusted prevalence by level of tooth loss was 56.1% (SE, 0.4%) for no tooth loss, 29.6% (SE, 0.3%) for 1-5 missing teeth, 9.7% (SE, 0.2%) for 6-31 missing teeth and 4.6% (SE, 0.1%) for total tooth loss. Adults with current depression had a significantly higher prevalence of nonuse of oral health services in the past year than those without this disorder (P < 0.001), after adjustment for age, sex, race/ethnicity, education, marital status, employment status, adverse health behaviours, chronic conditions, body mass index, assistive technology use and perceived social support. In logistic regression analyses employing tooth loss as a dichotomous outcome (0 versus ≥1) and as a nominal outcome (0 versus 1-5, 6-31, or all), adults with depression and anxiety were more likely to have tooth loss. Adults with current depression, lifetime diagnosed depression and lifetime diagnosed anxiety were significantly more likely to have had at least one tooth removed than those without each of these disorders (P < 0.001 for all), after fully adjusting for evaluated confounders (including use of oral health services). The adjusted odds of being in the 1-5 teeth removed, 6-31 teeth removed, or all teeth removed categories versus 0 teeth removed category were increased for adults with current depression versus those without (AOR = 1.35; 95% CI = 1.14-1.59; AOR = 1.83; 95% CI = 1.51-2.22; and AOR = 1.44; 95% CI = 1.11-1.86, respectively). The adjusted odds of being in the 1-5 teeth removed and 6-31 teeth removed categories versus 0 teeth removed category were also increased for adults with lifetime diagnosed depression or anxiety versus those without each of these disorders. Use of oral health services and tooth loss was associated with depression and anxiety after controlling for multiple confounders. © 2011 John Wiley & Sons A/S.

Background The Hispanic/Latino population is projected to increase from 16.7% to 30% by 2050. Previous US national surveys had minimal representation of Hispanic/Latino participants other than Mexican-Americans despite evidence suggesting -Hispanic/Latino country of origin and degree of acculturation influence their health outcomes. This study described prevalence and mean number of cavitated (D3) decayed and filled surfaces, missing teeth and edentulism for Hispanics/Latinos of different national origins. Methods The Hispanic Community Health Study/Study of Latinos (HCHS/SOL) conducted in-person examinations and interviews from over 16,000 participants aged 18–74 in four US cities between March 2008 and June 2011. Missing, filled and carious teeth were identified using modified methods of the National Health and Nutrition Examination Survey. Prevalence estimates (weighted percentages), weighted means, and standard errors were computed for measures. Results Prevalence of decayed surfaces (DS) ranged from 20.2% to 35.5%, depending on Hispanic/Latino background, while the prevalence of decayed and filled surfaces (DFS) ranged from 82.7% to 87.0%, indicating substantial dental treatment. The prevalence of missing teeth (MT) ranged from 49.8% to 63.8% and differed by Hispanic/Latino background. Significant differences in mean number of DS, DFS, and MT according Hispanic/Latino background group existed within each of the age groups and for females and males. Conclusions Oral health status does differ by Hispanic/Latino background even with adjustment for age, sex and other characteristics. Practical Implications These data indicate that Hispanic/Latinos in the US do receive restorative dental treatment and practitioners should consider that Hispanic/Latino origin is associated with oral health status.

To determine whether there is a relationship between the use of dental services and caries experience in adults and older adults from central Chile. A sample of 453 adults, 35-44 years of age, and 438 older adults, 65-74 years of age, was interviewed and examined using World Health Organisation (WHO) methods. Sociodemographic variables were also registered. Caries experience was assessed using the Decayed, Missing and Filled teeth (DMFT) index. Multiple linear regression models were used to determine whether there was an association between the independent variables and caries experience. Caries prevalence was 99.6% for adults [DMFT score = 14.89 (±6.16)] and 99.8% for older adults [DMFT score = 25.68 (±6.49)]. Less than half of the population - 41.7% of adults and 31.5% of older adults - received dental care. Regardless of the age group, there were no differences in the DMFT score between those who received and those who did not receive attention (P > 0.05). When the DMFT findings were analysed in greater detail, people who received dental care and urban participants had more fillings (P < 0.05) than did those who were not provided with attention or lived in rural areas, who, in turn, had more missing teeth (P < 0.05). A higher educational level was associated with a decrease of 1.15 DMFT points (P = 0.003) in the group of older adults. Adults and older adults from the Maule Region showed severe dental damage from caries. Although rurality and use of services do not seem to affect caries experience, they are associated with differences in fillings and missing teeth. © 2014 FDI World Dental Federation.

Background Poor oral hygiene has been proposed to contribute to head and neck cancer (HNC) risk, although causality and independency of some indicators are uncertain. This study investigates the relationship of five oral hygiene indicators with incident HNCs. Methods In a pooled analysis of 8925 HNC cases and 12 527 controls from 13 studies participating in the International Head and Neck Cancer Epidemiology Consortium, comparable data on good oral hygiene indicators were harmonized. These included: no denture wear, no gum disease (or bleeding), <5 missing teeth, tooth brushing at least daily, and visiting a dentist ≥once a year. Logistic regression was used to estimate the effects of each oral hygiene indicator and cumulative score on HNC risk, adjusting for tobacco smoking and alcohol consumption. Results Inverse associations with any HNC, in the hypothesized direction, were observed for <5 missing teeth [odds ratio (OR) = 0.78; 95% confidence interval (CI) 0.74, 0.82], annual dentist visit (OR = 0.82; 95% CI 0.78, 0.87), daily tooth brushing (OR = 0.83, 95% CI 0.79, 0.88), and no gum disease (OR = 0.94; 95% CI 0.89, 0.99), and no association was observed for wearing dentures. These associations were relatively consistent across specific cancer sites, especially for tooth brushing and dentist visits. The population attributable fraction for ≤ 2 out of 5 good oral hygiene indicators was 8.9% (95% CI 3.3%, 14%) for oral cavity cancer. Conclusion Good oral hygiene, as characterized by few missing teeth, annual dentist visits, and daily tooth brushing, may modestly reduce the risk of HNC. PMID:27234641

Implant failures are more common when multiple missing posterior teeth need lateral sinus floor elevation owing to inadequate tissue maturation after grafting. Effects of lateral window dimensions on vital bone formation have rarely been compared. To compare endo-sinus bone formation between two- and solo-window techniques to rehabilitate multiple missing posterior teeth that need substantial augmentation. Patients with severely atrophic posterior maxilla were randomized to receive lateral sinus floor elevation via solo or two bony windows. Bone core specimens harvested from lateral aspect of the augmentation sites were histomorphometrically analyzed. Proportions of mineralized bone (MB), bone substitute materials (BS), and nonmineralized tissue (NMT) were quantified. Twenty-one patients underwent 23 maxillary sinus augmentations. One patient in each group dropped out during the follow-up period. Lateral window dimensions were 81.65 ± 4.59 and 118.04 ± 19.53 mm 2 in the test and control groups, respectively. Histomorphometric analysis revealed mean MB of 42.32% ± 13.07% and 26.00% ± 15.23%, BS of 40.34% ± 9.52% and 60.03% ± 10.13%, and NMT of 18.14% ± 14.24% and 14.75% ± 10.38% in test and control groups, respectively, with significant differences. The two-window technique could facilitate faster maturation and consolidation of the grafted volume and is an effective alternative for rehabilitation of severely atrophic posterior maxilla with multiple missing posterior teeth. © 2017 Wiley Periodicals, Inc.

2018-01-01

To evaluate the current status of all-ceramic inlay-retained fixed dental prostheses (CIR-FDPs) for the replacement of posterior teeth. Screening of titles and abstracts, full-text analysis for inclusion eligibility, quality assessment, data extraction and evaluation of the scientific evidence were performed independently by two reviewers. The electronic databases MEDLINE/PubMed, EMBASE, Cochrane Central Register of Controlled Trials, and Compludoc were searched with no restriction to publication date or language. The quality of the studies was evaluated through: the original 'QDP' ('Questionnaire for selecting articles on Dental Prostheses') (for research papers); the 'Guidelines for managing overviews' of the Evidence-Based Medicine Working Group (for reviews); the Cochrane risk of bias tool; and the GRADE scale for grading scientific evidence. This review started with 4942 articles, which were narrowed down to 23 according to the selection criteria. The data was not statistically treated because of the heterogeneity of the studies. Zirconia-based CIR-FDPs may be recommended for restoring posterior single missing teeth, although the prosthesis/tooth bonded interface has yet to be improved. The addition of lateral wings to the classical inlay preparation seems promising. The weakest parts of CIR-FDPs are the connectors and retainers, while caries and endodontic problems are the most common biological complications. The fabrication of CIR-FDPs with monolithic zirconia may eliminate chipping problems. A three-unit CIR-FDP is a viable treatment option for replacing a posterior missing tooth. Appropriate case selection, abutment preparation and luting procedures may be decisive for clinical success. Copyright © 2017 Japan Prosthodontic Society. Published by Elsevier Ltd.

Inverse associations with any HNC, in the hypothesized direction, were observed for <5 missing teeth [odds ratio (OR) = 0.78; 95% confidence interval (CI) 0.74, 0.82], annual dentist visit (OR = 0.82; 95% CI 0.78, 0.87), daily tooth brushing (OR = 0.83, 95% CI 0.79, 0.88), and no gum disease (OR = 0.94; 95% CI 0.89, 0.99), and no association was observed for wearing dentures. These associations were relatively consistent across specific cancer sites, especially for tooth brushing and dentist visits. The population attributable fraction for ≤ 2 out of 5 good oral hygiene indicators was 8.9% (95% CI 3.3%, 14%) for oral cavity cancer. Good oral hygiene, as characterized by few missing teeth, annual dentist visits, and daily tooth brushing, may modestly reduce the risk of HNC. © The Author 2016.

To investigate phenotypic differences in dental development between isolated oligodontia and oligodontia-ectodermal dysplasia (ED). A total of 129 patients diagnosed with isolated oligodontia and 22 patients with oligodontia as part of ED were eligible. The phenotype of dental development was assessed for the frequency of missing a certain tooth, dental age, development of each tooth present, abnormal size and abnormal shape of teeth. The data were analysed building linear, ordinal and logistic regression models. Compared to patients with isolated oligodontia, patients with oligodontia-ED missed more frequently central incisors and second molars in both jaws, and lateral incisors in the mandible (P < .05). Oligodontia-ED was associated with delayed development of the permanent dentition (β = -0.10; 95% CI: -0.17, -0.03). Specifically, the maxillary teeth: right central incisor, right lateral incisor, right second premolar and left second premolar were delayed approximately from 2 to 4 developmental stages. In addition, the left mandibular second premolar was 3 developmental stages delayed. Abnormal shape of teeth was 7 times more evident in patients with oligodontia-ED compared to patients with isolated oligodontia (OR = 6.54; 95% CI: 2.34, 18.28). The abnormal size of teeth was not a distinctive characteristic for oligodontia-ED. Oligodontia-ED distinguishes from isolated oligodontia by more disturbances in dental development. The abnormal shape of incisors and canines in a patient with oligodontia can raise suspicions for accompanying ectodermal abnormalities. © 2017 The Authors.

In a young woman, aged 18 years 8 months, who had an anterior open bite and anterior spacing, the right and left mandibular first molar extraction spaces were closed by protraction of the second and third molars without reciprocal retraction of the incisors and the premolars. The amounts of protraction for the second molars were 12 mm on the right side and 11 mm on the left side. Two miniscrews were inserted into the mesiobuccal side of the edentulous spaces, and 2 more screws were inserted into the anterior sites after removing previous miniscrews. In addition, 4 miniscrews were inserted into the buccal and palatal sides between the first and second maxillary molars to intrude the maxillary posterior teeth, which had extruded into the missing mandibular spaces. Careful biomechanical consideration was used to prevent extrusion of the molars and worsening of the anterior open bite from protraction of the posterior teeth. Ultimately, the anterior open bite was corrected by both intrusion of the maxillary molars and extrusion of the maxillary anterior teeth. Excellent occlusion and correction of the anterior open bite were achieved without tipping, rotation of the posterior teeth, or other problems. The right mandibular third molar, which had been impacted at the beginning of treatment, erupted into the second molar space and functioned properly. At the 1-year follow-up examination, the patient had a slight anterior open bite, but closure of the first molar extraction spaces was well maintained.

Dental implant is a method to replacement of missing teeth. It is important for replacing the missed anterior teeth. In vitro method is a safe method for evaluation of stress distribution. Finite element analysis as an in vitro method evaluated stress distribution around replacement of six maxillary anterior teeth implants in three models of maxillary arch. In this in vitro study, using ABAQUS software (Simulia Corporation, Vélizy-Villacoublay, France), implant simulation was performed for reconstruction of six maxillary anterior teeth in three models. Two implants were placed on both sides of the canine tooth region (A model); two implants on both sides of the canine tooth region and another on one side of the central incisor region (B model); and two implants on both sides of the canine tooth region and two implants in the central incisor area (C model). All implants evaluated in three arch forms (tapered, ovoid, and square). Data were analyzed by finite analysis software. Von Mises stress by increasing of implant number was reduced. In a comparison of A model in each maxillary arch, the stress created in the cortical and cancellous bones in the square arch was less than ovoid and tapered arches. The stress created in implants and cortical and cancellous bones in C model was less than A and B models. The C model (four-implant) reduced the stress distribution in cortical and cancellous bones, but this pattern must be evaluated according to arch form and cost benefit of patients.

To date, the evidence supporting the benefits of dental visiting comes from cross-sectional studies. We investigated whether long-term routine dental visiting was associated with lower experience of dental caries and missing teeth, and better self-rated oral health, by age 32. A prospective cohort study in New Zealand examined 932 participants’ use of dentistry at ages 15, 18, 26, and 32. At each age, routine attenders (RAs) were identified as those who (a) usually visited for a check-up, and (b) had made a dental visit during the previous 12 months. Routine attending prevalence fell from 82% at age 15 to 28% by 32. At any given age, routine attenders had better-than-average oral health, fewer had teeth missing due to caries, and they had lower mean DS and DMFS scores. By age 32, routine attenders had better self-reported oral health and less tooth loss and caries. The longer routine attendance was maintained, the stronger the effect. Routine dental attendance is associated with better oral health. PMID:20093674

This article presents a case report of a 20 year old female who was very much dissatisfied with her facial appearance and smile.On examination, it was found that there was a Angles class II division 1 malocclusion and a generalised spacing in the anterior teeth, with a retained, deciduous, left maxillary canine and a malposed 15. On radiographic examination, an impacted 18, 23 was noticed. As the part of the treatment plan, the retained deciduous canine and the impacted permanent canine were extracted and an orthodontic correction of the malocclusion was accomplished. The missing canine was planned to be replaced with a fixed partial denture.The short clinical crown height of the abutment teeth was increased by crown lengthening procedures and the pontic space was contoured to receive a ovate pontic by using diode lasers. The missing tooth was restored by using an all ceramic three unit zirconia bridge. This multi-disciplinary approach improved the smile of the patient and it ultimately enhanced her aesthetics and self confidence.

The purpose of this study was to investigate the relationship between the number of missing teeth (MT) and the statuses of oral environmental factors (the stimulated salivary flow rate, buffering capacity, and the counts of mutans streptococci, lactobacilli, and Candida) in the elderly. The subjects were 64 elderly subjects with fixed prostheses and 49 who wore removable partial dentures aged over 65 years. We used one-way ANOVA to test for overall differences of the number of MT among 5 oral environmental factors. The significant differences were observed in the lactobacilli counts for different number of MT. The number of MT increased with an increase in the lactobacilli counts with removable denture. In conclusion, for the patients wearing removable dentures, increasing number of MT was associated with an increase in the lactobacilli counts in saliva. For the patients with crowns and fixed partial dentures, the number of MT was not significantly affected by salivary mutans streptococci, lactobacilli, and Candida counts.

The management of tooth wear has been a subject of increasing interest from both preventive and restorative points of view. This paper describes the full mouth rehabilitation of a 63-year-old bruxer man with a severely worn dentition and other dental problems including unsuitable restorations and several missing teeth. The treatment entailed using cast posts and cores, metal-ceramic restorations, and a removable partial denture. As with the treatment procedure of such cases, equal-intensity centric occlusal contacts on all teeth and an anterior guidance in harmony with functional jaw movements were especially taken into account.

Satisfactory restoration in a patient with a partially edentulous situation can be challenging especially when unilateral or bilateral posterior segment of teeth is missing. Successful restoration can be done with various conventional and contemporary treatment options. One such treatment modality is attachment-retained cast partial dentures. A key to success for an attachment retained cast partial denture is the strategic selection of teeth for retention. This clinical report discusses rehabilitation of a patient with the help of a combined prosthesis in the upper arch and stud retained overdenture in the lower arch. PMID:26929527

The treatment modality, a continuous occlusal rest removable partial denture, not only restored missing teeth but also stabilized the remaining dentition in a patient with advanced periodontal attachment loss. By engaging the guiding planes at the mesial surfaces of the abutments anteriorly and also the distal surfaces of the abutments posteriorly, the remaining teeth, with varying amounts of mobility, were splinted together by the framework. This conservative treatment option allows flexibility for easy repair during the life span of the prosthesis.

Cloning of the breakpoints of a de novo inversion of chromosome 8, inv (8)(p11.2q23.1) in a patient with Ambras syndrome.

Ambras syndrome (AMS) is a unique form of universal congenital hypertrichosis. In patients with this syndrome, the whole body is covered with fine long hair, except for areas where normally no hair grows. There is accompanying facial dysmorphism and teeth abnormalities, including retarded first and second dentition and absence of teeth. In 1993, Baumeister et al. reported an isolated case of Ambras syndrome in association with a pericentric inversion of chromosome 8. Subsequently, another patient with congenital hypertrichosis and rearrangement of chromosome 8 was reported by Balducci et al. (1998). Both of these patients have a breakpoint in 8q22 in common suggesting that this region of chromosome 8 contains a gene involved in regulation of hair growth. In order to precisely determine the nature of the rearrangement in the case of Ambras syndrome, we have used fluorescent in situ hybridization (FISH) analysis. We have cloned the inversion breakpoints in this patient and generated a detailed physical map of the inversion breakpoint interval. Analysis of the transcripts that map in the vicinity of the breakpoints revealed that the inversion does not disrupt a gene, and suggests that the phenotype is caused by a position effect.

This study explored ethnic inequalities in dental caries among adults and assessed the role of socioeconomic position (SEP) in explaining those inequalities. We analysed data on 2013 adults aged 16-65 years, from the East London Oral Health Inequality (ELOHI) Study, which included a random sample of adults and children living in East London in 2009-10. Participants completed a questionnaire and were clinically examined for dental caries at home. Dental caries was measured using the number of decayed, missing and filled teeth or DMFT index. Ethnic inequalities in dental caries were assessed in negative binomial regression models before and after adjustment for demographic (sex and age groups) and SEP measures (education and socioeconomic classification). White Eastern European and White Other had higher DMFT, whereas all Asian (Pakistani, Indian, Bangladeshi and Other) and all Black (African, Caribbean and Other) ethnic groups had lower DMFT than White British. Similar inequalities were found for the number of filled and missing teeth, but there were no differences in the number of decayed teeth between ethnic groups. This study showed considerable disparities in dental caries between and within the major ethnic categories, which were independent of demographics and SEP. © The Author 2015.

Slade, G D; Sanders, A E; Do, L; Roberts-Thomson, K; Spencer, A J

2013-04-01

Systematic reviews produce conflicting conclusions regarding dental caries-preventive effects of water fluoridation in adults. The authors investigated the relationship using data from the nationally representative 2004-2006 Australian National Survey of Adult Oral Health. Effects were compared between the pre-fluoridation cohort born before 1960 (n = 2,270) and the cohort born between 1960 and 1990 (n = 1,509), when widespread implementation of fluoridation increased population coverage from < 1% to 67%. Residential history questionnaires determined the percentage of each person's lifetime exposed to fluoridated water. Examiners recorded decayed, missing, and filled teeth (DMF-Teeth) and decayed and filled tooth surfaces (DF-Surfaces). Socio-demographic and preventive dental behaviors were included in multivariable least-squares regression models adjusted for potential confounding. In fully adjusted models, > 75% of lifetime exposure to fluoridation relative to < 25% of lifetime exposure was associated with 11% and 10% fewer DMF-Teeth in the pre-1960 (p < .0001) and 1960-1990 cohorts (p = .018), respectively. Corresponding reductions in DF-Surfaces were 30% (p < .001) and 21% (p < .001). Findings for intermediate fluoridation exposure suggested a dose-response relationship. Results were consistent in sensitivity analyses accounting for missing data. In this nationally representative sample of Australian adults, caries-preventive effects of water fluoridation were at least as great in adults born before widespread implementation of fluoridation as after widespread implementation of fluoridation.

Aim To investigate the prevalence of dental caries and treatment needs in schoolchildren aged 7-14 years from Zagreb. Methods Dental examinations based on the World Health Organization criteria were performed on 1168 children in the period 2009-2010. The teeth were clinically examined with standard dental instruments using visual-tactile method under standard dental light. We recorded the clinical indexes of decayed, missed, and filled teeth (DMFT and dmft; upper-case letters refer to permanent and lower-case letters to primary teeth) and decayed, missed, and filled surfaces (DMFS), as well as the significant caries index (SiC). Results The median DMFT and DMFS of all children were 3 and 4, respectively. The median DMFT and DMFS of 12-year-old children were 4 and 5, respectively. The highest median DMFT score of 7 was found among 14-year-old children. There was a significant difference between age groups (7-10 years and 11-14 years) in DMFT and DMFS. Among 8-year-old children, the median dmft index was the highest (5.5) and SiC index was 7.4. As far as the location of caries on the surface of the first permanent molar is concerned, caries occurred mostly in the central occlusal surface (27.6%). Conclusion Our results showed a high caries prevalence among schoolchildren in Zagreb, indicating a need for an extensive program of primary oral health care. PMID:22180264

Oral health effects, brushing habits and management of methamphetamine users for the general dental practitioner.

PubMed

Smit, D A; Naidoo, S

Methamphetamine is a synthetic drug commonly abused in South Africa and is highly addictive. Users have a higher prevalence of dental caries compared to non-users and the classical caries pattern found in methamphetamine users is termed 'meth mouth'. The increased consumption of soft drinks and the absence of saliva are the main risk factors for 'meth mouth'. To determine the oral health status of individuals using methamphetamine. A cross-sectional study was conducted on a convenience sample of 308 self-reported methamphetamine users at 22 specialised substance addiction treatment centres in the Western Cape, South Africa. There was a significant difference in tooth brushing frequency when using methamphetamine (p = 0.0000022; χ(2) = 23.84; OR = 3.25). The mean decayed, missing and filled teeth score was ten and there was an association between the mean number of decayed teeth and the duration of drug addiction (p = 0.0071; χ(2) = 12.07). Users who were using methamphetamine for less than four years had fewer missing teeth compared to those who were using methamphetamine for more than four years. When methamphetamine abuse is detected, the dentist can play a key role in early management of drug addiction by referring the patient to specialised substance addiction treatment centres. In addition, by restoring the dental appearance, users may regain their self-esteem and improve their oral health quality of life.

Inconsistency in the analysis of morphological deformities in chironomidae (Insecta: Diptera) larvae.

2015-08-01

The incidence of morphological deformities of chironomid larvae as an indicator of sediment toxicity has been studied for decades. However, standards for deformity analysis are lacking. The authors evaluated whether 25 experts diagnosed larval deformities in a similar manner. Based on high-quality digital images, the experts rated 211 menta of Chironomus spp. larvae as normal or deformed. The larvae were from a site with polluted sediments or from a reference site. The authors revealed this to a random half of the experts, and the rest conducted the assessment blind. The authors quantified the interrater agreement by kappa coefficient, tested whether open and blind assessments differed in deformity incidence and in differentiation between the sites, and identified those deformity types rated most consistently or inconsistently. The total deformity incidence varied greatly, from 10.9% to 66.4% among experts. Kappa coefficient across rater pairs averaged 0.52, indicating insufficient agreement. The deformity types rated most consistently were those missing teeth or with extra teeth. The open and blind assessments did not differ, but differentiation between sites was clearest for raters who counted primarily absolute deformities such as missing and extra teeth and excluded apparent mechanical aberrations or deviations in tooth size or symmetry. The highly differing criteria in deformity assignment have likely led to inconsistent results in midge larval deformity studies and indicate an urgent need for standardization of the analysis. © 2015 SETAC.

Little evidence is available regarding the dental health of victims of chemical warfare in Iran. Therefore, in this study, we examined the decayed, missing, and filled teeth index (DMFT), community periodontal index of treatment needs (CPITN), and saliva secretion rate of chemical warfare victims living in the province of Isfahan in Iran. This case-control study was conducted with 300 chemical warfare victims as the treatment group and 300 age-matched individuals without exposure to chemical warfare as the control group. DMFT and CPITN indices and saliva secretion rate were measured and compared between the two groups. Chemical warfare victims had significantly higher scores than the control group for decayed teeth (4.25 ± 3.88 vs 3.52 ± 2.81; P=0.009), missing teeth (8.79 ± 9.3 vs 6.15 ± 8.43; P<0.001), total DMFT index (17.00 ± 6.72 vs 13.20 ± 6.89; P<0.001), and CPTIN (2.81 ± 0.81 vs 1.71 ± 1.04; P<0.001). However, no significant difference was observed between the two groups in filled teeth (4.00 ± 4.2 vs 3.59 ± 2.48; P=0.148). The level of saliva secretion in warfare victims was significantly lower than that in the control group (1.71 ± 0.05 vs 3.85 ± 1.95 cc/5 min; P<0.001). Chemical warfare victims have relatively poor dental/oral health. Chemical injury might cause a dysfunction in saliva secretion, with decrease in saliva secretion increasing the risk for tooth decay and periodontal disorders. Further research is required to find out the exact underlying mechanisms and the factors associated with poor dental/oral health in chemical warfare victims.

Objectives The present study aimed to investigate the prevalence and correlates of dental caries in elderly population in northeast China. Methods A community-based, cross-sectional study among 2376 elderly subjects (age: 65–74 years) from nine urban areas and nine rural areas in three provinces of northeast China was conducted using multistage stratified random sampling per the World Health Organization oral health survey methodology. Decayed-missing-filled teeth (DMFT) and decayed-filled teeth (DFT) indices were used to evaluate the prevalence of dental caries. Face-to-face questionnaire survey on oral health was performed in a randomly selected subset (n = 1197). T test and chi square test were employed to compare groups for continuous and categorical variables, respectively. Multivariate logistic regression was used to estimate odds ratios (ORs) and corresponding confidence intervals (CIs). Results 67.5% of elderly subjects reported dental caries (average DFT = 2.68±3.40), and the prevalence was higher in urban areas (P<0.01). Missing teeth accounted for 80.72% of DMFT, and filled teeth due to caries accounted for 2.08% with a rate higher in urban areas (P<0.01). Logistic regression analysis indicated significant association among elderly population in urban areas (OR 1.713; 95% CI 1.337–2.195), smoking (OR 1.779; 95% CI 1.384–2.288), and individuals without dental insurance (OR 2.050; 95% CI 1.120–3.754) with dental caries. Conclusions The prevalence of dental caries in the elderly population in northeast China is high. The elderly from urban areas who smoke and who do not have a dental insurance are at a higher risk to develop dental caries. PMID:24260129

Dho, Yun-Sik; Kim, Seung-Ki; Wang, Kyu-Chang

2015-01-01

Congenital dermal sinus (CDS) is a type of occult spinal dysraphism characterized by a midline skin dimple. A 12-month-old girl presented with fever and ascending quadriparesis. She had a midline skin dimple in the upper sacral area that had been discovered in her neonatal period. Imaging studies revealed a holocord intramedullary abscess and CDS. Overlooking CDS or misdiagnosing it as benign sacrococcygeal dimple may lead to catastrophic infection and cause serious neurological deficits. Therefore, further imaging work-up or consultation with a pediatric neurosurgeon is recommended following discovery of any atypical-looking dimples in the midline. PMID:25810867

Prevalence of abnormalities in dental structure, position, and eruption pattern in a population of unilateral and bilateral cleft lip and palate patients.

2008-03-01

To evaluate the dental characteristics of patients subjected to a protocol that included early secondary gingivoalveoloplasty (ESGAP). Panoramic radiographs of 87 patients with unilateral cleft lip and palate (UCLP) and 29 with bilateral cleft lip and palate (BCLP) were evaluated. Missing and supernumerary teeth were also quantified on the cleft and noncleft side and in the maxilla and mandible. Crown and root malformations and tooth rotations were quantified. A subsample in permanent dentition was extrapolated to analyze canine eruption patterns. A total of 48.8% of the UCLP patients presented with missing permanent lateral incisors in the cleft area and 6.1% contralaterally. A total of 4.9% presented with missing second maxillary premolars on the cleft site and 1.2% contralaterally. A total of 7.3% presented with supernumerary lateral incisors, and 45% of the BCLP cleft sites presented with missing lateral incisors, while 25% of the cleft sites presented second maxillary premolars agenesis. Five percent of the cleft sites presented with supernumerary lateral incisors. Evaluation of the subsample in permanent dentition showed that 15.5% had a canine retention and 4.4% of the canines had to be surgically exposed. A significant association was observed between canine inclination and retention but not with absence of the lateral incisor. The frequency of dental anomalies in this sample was similar to other cleft populations. As surgical trauma has been suggested to damage forming teeth, the results of this study indicated that ESGAP has no detrimental influence on subsequent dental development.

Dental anomalies are common congenital malformations that can occur either as isolated findings or as part of a syndrome. This review focuses on genetic causes of abnormal tooth development and the implications of these abnormalities for clinical care. As an introduction, we describe general insights into the genetics of tooth development obtained from mouse and zebrafish models. This is followed by a discussion of isolated as well as syndromic tooth agenesis, including Van der Woude syndrome, ectodermal dysplasias, oral-facial-digital syndrome type I, Rieger syndrome, holoprosencephaly, and tooth anomalies associated with cleft lip and palate. Next, we review delayed formation and eruption of teeth, as well as abnormalities in tooth size, shape and form. Finally, isolated and syndromic causes of supernumerary teeth are considered, including cleidocranial dysplasia and Gardner syndrome. PMID:24124058

Various programmes for adults with congenitally malformed hearts have been developed, but detailed descriptions of content, rationale and goals are often missing. The aim of this study was to describe and make an initial evaluation of a follow-up model for adults with congenitally malformed hearts, focusing on education and psychosocial support by a multidisciplinary team (EPS). The model is described in steps and evaluated with regards to perceptions of knowledge, anxiety and satisfaction. The EPS model included a policlinic visit to the physician/nurse (medical consultation, computer-based and individual education face-to-face as well as psychosocial support) and a 1-month telephone follow-up. Fifty-five adults (mean age 34, 29 women) with the nine most common forms of congenitally malformed hearts participated in the EPS model as well as the 3-months follow-up. Knowledge about congenital heart malformation had increased in 40% of the participants at the 3-months follow-up. This study describes and evaluates a model that combines a multidisciplinary approach and computer-based education for follow-up of adults with congenitally malformed hearts. The EPS model was found to increase self-estimated knowledge, but further evaluations need to be conducted to prove patient-centred outcomes over time. The model is now ready to be implemented in adults with congenitally malformed hearts. Copyright © 2010 Elsevier Ireland Ltd. All rights reserved.

Museum specimens (maxillae and/or mandibles) from 371 American black bears (Ursus americanus) acquired between 1889 and 2006 were examined macroscopically according to predefined criteria, and 348 were included in this study. Of the 348 specimens, 126 (36.2%) were from male animals, 106 (30.5%) were from female animals and 116 (33.3%) were from animals of unknown sex. Specimen ages ranged from young adult (n = 63, 18.1%) to adult (n = 285, 81.9%), with juveniles excluded from the study. The number of teeth available for examination was 12,019 (82.2%); 7.0% of teeth were absent artefactually, 0.4% were deemed absent due to acquired tooth loss and 9.7% were absent congenitally. In 43 specimens (12.3%), 82 teeth (0.68%) were small vestigial structures with crowns that were flush with the level of surrounding alveolar bone. The remaining teeth (99.3%) were of normal morphology. Only three supernumerary teeth and three instances of enamel hypoplasia were encountered. Persistent deciduous teeth or teeth with an aberrant number of roots were not encountered in any of the specimens. Approximately one-third of the teeth examined (4,543, 37.8%) displayed attrition/abrasion, affecting nearly all of the specimens (n = 338, 97.1%). Incisor and molar teeth accounted for 52.5% and 34.3% of the affected teeth, respectively, with significantly more adults affected than young adults. Dental fractures were noted in 63 bears, affecting 18.1% of specimens and 1.0% of the total number of present teeth. The canine teeth were most often fractured, with adults having significantly more complicated crown fractures of these teeth than young adults. There were 11 specimens (3.2%) that displayed periapical lesions, affecting 12 (0.1%) dental alveoli. There were 179 specimens (51.4%) displaying bony changes indicative of periodontitis, affecting 816 (6.8%) dental alveoli. The proportion of adult bears affected by periodontitis (57.9%) was significantly greater than that of young adults (22.2%). Exactly half of the specimens (n = 174) possessed lesions consistent with mild temporomandibular joint osteoarthritis. The occurrence and severity of the dental pathology encountered in this study may play an important role in the morbidity and mortality of the American black bear. Copyright © 2016 Elsevier Ltd.

Hypodontia is defined as the congenital absence of one or a few teeth, and is also the most common anomaly in dental development. This condition occurs either individually or as part of the symptoms of a syndrome, and it is more common in permanent teeth than in deciduous teeth, reporting a prevalence of between 1.6 and 9.6%. The objective of this study is to investigate the prevalence of hypodontia for permanent teeth in nine- to 14-year-old children who attended the Mashhad School of Dentistry in 2007. We conducted this descriptive, analytical, cross-sectional study, to determine the mentioned aims. In this descriptive, cross-sectional study, panoramic radiographs belonging to 600 children (351 girls and 249 boys), aged nine to 14 years, were available for examination. All related findings were recorded in the respective forms. The data were processed using Exact and Chi-square tests. The prevalence of hypodontia in the girls was 9.2%, in the boys 8.8%, and in both sexes combined 9%. The most and the least frequent cases of absent teeth were the mandibular second premolars and the maxillary central incisor (only one child), respectively. The most commonly absent teeth were the mandibular second premolars, the maxillary lateral incisors, the mandibular central incisor, and the maxillary second premolars, in that order. This study showed a high frequency of hypodontia among the understudied population. Thus, due to the complicated treatment, accurate examination of children for on-time diagnosis of this developmental anomaly is crucial.

To optimize long-term outcomes, patients with congenital heart disease (CHD) should adopt health-promoting behaviors. Studies on health behavior in afflicted patients are scarce and comparability of study results is limited. To enlarge the body of evidence, we have developed the Health Behavior Scale-Congenital Heart Disease (HBS-CHD). We examined the psychometric properties of the HBS-CHD by providing evidence for (a) the content validity; (b) validity based on the relationships with other variables; (c) reliability in terms of stability; and (d) responsiveness. Ten experts rated the relevance of the HBS-CHD items. The item content validity index (I-CVI) and the averaged scale content validity index (S-CVI/Ave); the modified multi-rater Kappa and proportion of missing values for each question were calculated. Relationships with other variables were evaluated using six hypotheses that were tested in 429 adolescents with CHD. Stability of the instrument was assessed using Heise's method; and responsiveness was tested by calculating the Guyatt's Responsiveness Index (GRI). Overall, 86.3% of the items had a good to excellent content validity; the S-CVI/Ave (0.81) and multi-rater Kappa (0.78) were adequate. The average proportion of missing values was low (1.2%). Because five out of six hypotheses were confirmed, evidence for the validity of the HBS-CHD based on relationships with other variables was provided. The stability of the instrument could not be confirmed based on our data. The GRI showed good to excellent capacity of the HBS-CHD to detect clinical changes in the health behavior over time. We found that the HBS-CHD is a valid and responsive questionnaire to assess health behaviors in patients with CHD.

Objectives: The purpose of this study was to assess the oral health status of children with cerebral palsy (CP) in Dubai, United Arab Emirates (UAE). Materials and Methods: Eighty-four CP and 125 healthy children were recruited from special needs centers and private/public schools in Dubai. A dental examination for decayed-missing-filled teeth in primary dentition (dmft)/Decayed-Missing-Filled teeth in permanent dentition (DMFT) indices, simplified oral hygiene index, calculus index (CI), and oral debris index was conducted. In addition, assessments of occlusal, dentofacial, soft tissue anomalies and erosion were conducted. Statistical analysis was conducted using SPSS for Windows, version 20.0 (SPSS Inc., Chicago, IL, USA). Results: DMFT/dmft scores were comparable in both groups. CI was significantly higher among children with CP. CP patients had a significantly higher proportion of anterior open bite, anterior spacing, Class II molar Angle malocclusion, trauma, high-arched palate, tongue thrust, lymphadenopathy, angular cheilitis, macroglossia, drooling, and erosion as compared to controls. Conclusions: The study highlighted peculiar characteristics and needs for the CP patients in Dubai, UAE. PMID:29285470

2017-03-01

Fourteen dentists at different practices in the UK assessed the dental charts of 1128 patients who were new to the dentist but not new to the practice; 44% of the dental charts were found to be inaccurate. Inaccuracy of the individual practice-based charts ranged between 16% for the best performing practices to 83% for the worst: 5% of dental charts had too many teeth charted and 5% had too few teeth charted; 13% of charts had missed amalgam restorations and 18% had missed tooth-coloured restorations; 5% of charts had amalgam restorations recorded but with the surfaces incorrect (eg an MO restoration charted but a DO restoration actually present); 9% of charts had tooth-coloured restoration surfaces incorrectly recorded. For 7.5% of charts, amalgams were charted but not actually present. Other inaccuracies were also noted. The authors reinforce the requirements of the GDC, the advice of defence organizations, and the forensic importance of accurate dental charts. Clinical relevance: Dental charting forms part of the patient’s dental records, and the GDC requires dentists to maintain complete and accurate dental records.

Tooth loss and its association with dietary intake and diet quality in American adults.

Zhu, Yong; Hollis, James H

2014-11-01

To investigate associations between the number of natural teeth and energy intake, nutrient intake, and diet quality in adults. Eligible adults who participated in the National Health and Nutrition Examination Survey during 2005-2008 were included in the present study (n=9140). Participants were classified into three groups depending on the total number of natural teeth (excluding third molars): full dentition (28 teeth), moderate dentition (21-27 teeth), and poor dentition (20 teeth or less). Dietary intake and diet quality were estimated from the first 24-h dietary recall data. Participants in the poor dentition group had significantly lower energy intake than those with moderate dentition (P<0.05), however, both groups did not significantly differ from those who had full dentition. Adjusting for sociodemographic characteristics, physical activity, smoking status, and energy intake, the intake of protein as well as most vitamins and minerals were positively associated with the total number of natural teeth (P<0.05); an inverse association was observed for carbohydrate intake (P<0.001). Diet quality, as measured by the Healthy Eating Index 2005, was inversely associated with tooth loss (P<0.001). Tooth loss in adults is associated with lower diet quality and reduced intake of most nutrients; this may partly explain for the higher risk of chronic diseases in this population. People with missing teeth are recommended to monitor their dietary intake to avoid nutrient deficiency and to improve their diet quality for better health. Copyright © 2014 Elsevier Ltd.

Brain structure is changed in congenital anosmia.

Frasnelli, Johannes; Fark, Therese; Lehmann, Jacqueline; Gerber, Johannes; Hummel, Thomas

2013-12-01

Olfactory function in healthy people correlates with structural features of both the olfactory bulb and higher order olfactory processing areas, but we do not yet know how congenital anosmia affects these latter structures. In order to examine this question closer, we acquired T1 weighted magnetic resonance images from 17 subjects with congenital anosmia and from 17 age- and sex-matched controls. We compared white and gray matter volumes as well as cortical thickness between both groups. We found subjects with congenital anosmia to exhibit larger gray matter volumes in the left entorhinal and piriform cortices. Further, they had thicker orbitofrontal cortices bilaterally. Their left piriform cortex was also thicker than that of controls. These findings are in contrast to those observed in acquired anosmia, where reduced olfactory function is associated with reduced volumes and thickness. However, they fit well with observations from other sensory systems, e.g., vision, where congenital sensory loss is associated with a thicker primary cortex. This finding has been attributed to reduced or absent synaptic pruning as a result of missing peripheral sensory input. Our findings suggest that similar mechanisms take place in the olfactory system. © 2013.

The aim of the study was to (a) analyse dental occlusion and determine the need for orthodontic treatment of persons with osteogenesis imperfecta (OI) in comparison with the healthy population and (b) investigate the associations between OI and malocclusion. A case-control study included 26 OI persons and 400 healthy participants (control group). Occlusal features and the need for orthodontic treatment were defined according to Dental Health Component-Index of Orthodontic Treatment Need and Dental Aesthetic Index. Results showed that Angle Class I, II, and III relationship was found in 23.1%, 3.8%, and 73.1% of OI group, and in the control group, it was 67%, 17.5%, and 15.5%, respectively. OI group had significantly higher prevalence of reverse overjet >1 mm (76.9%), missing teeth (42.3%), posterior crossbite (34.6%), and open bite >2 mm (19.2%) compared to the control group (8.5%, 2.2%, 6.2%, and 3.5%, respectively). OI group had less incisal segment crowding and more incisal segment spacing than the control group ( p  < 0.05). The need for orthodontic treatment of OI group according to Dental Health Component-Index of Orthodontic Treatment Need and Dental Aesthetic Index was 88.5% and 61.5%, respectively, while in the control group, it was 24.8% and 51.8%. The malocclusion in OI persons was associated with reverse overjet > 1 mm (OR = 13.3, 95% CI = 3.9-44.7, p  < .001), Angle Class III malocclusion (OR = 8.0, 95% CI = 2.0-30.8, p  = .003), and missing teeth (OR = 4.7, 95% CI = 1.0-22.4, p  = .049). In conclusion, there is the high probability of malocclusion in OI persons. Persons with OI require early orthodontic treatment because of significant correlation of OI disease with Angle Class III malocclusion, reverse overjet, and missing teeth.

Methamphetamine (MA) users are assumed to have a high burden of tooth decay. Less clear is how the distribution and severity of dental caries in MA users differ from the general population. Using a covariate-balancing propensity score strategy, we investigated the differential effects of MA use on dental caries by comparing the patterns of decayed, missing, and filled teeth in a community sample of 571 MA users with a subset of 2,755 demographically similar control individuals selected from a National Health and Nutrition Examination Survey (NHANES) cohort. Recruited over a 2-y period with a stratified sampling protocol, the MA users underwent comprehensive dental examinations by 3 trained and calibrated dentists using NHANES protocols. Propensity scores were estimated with logistic regression based on background characteristics, and a subset of closely matched subjects was stratified into quintiles for comparisons. MA users were twice as likely to have untreated caries (odds ratio [OR] = 2.08; 95% confidence interval [95% CI]: 1.55 to 2.78) and 4 times more likely to have caries experience (OR = 4.06; 95% CI: 2.24 to 7.34) than the control group of NHANES participants. Additionally, MA users were twice as likely to have 2 more decayed, missing, or filled teeth (OR = 2.08; 95% CI: 1.29 to 2.79) than the NHANES participants. The differential involvement of the teeth surfaces in MA users was quite distinctive, with carious surface involvement being highest for the maxillary central incisors, followed by maxillary posterior premolars and molars. Users injecting MA had significantly higher rates of tooth decay compared with noninjectors (P = 0.04). Although MA users experienced decayed and missing dental surfaces more frequently than NHANES participants, NHANES participants had more restored surfaces, especially on molars. The high rates and distinctive patterns of dental caries observed could be used 1) to alert dentists to covert MA use in their patients and 2) as the basis for comprehensive management strategies. © International & American Associations for Dental Research 2016.

The dental care must be driven by preventive and curative measures that can contribute to the population's oral health promotion. To evaluate the impact of the actions proposed by a comprehensive dental care protocol (CDCP) on the oral health condition of primary care users. The sample consisted of 32 volunteers, assisted throughout the six phases proposed by the CDCP: diagnosis of dental needs; resolution of urgencies; restorative interventions; application of promotional measures; evaluation of the achieved health level; and periodic controls. Data were collected through clinical exams, which measured the simplified oral hygiene index (OHI-S), gingival bleeding index (GBI) and the decayed, missing and filled teeth (DMFT) Index, before and after the CDCP was implemented. Statistical analysis consisted of the Wilcoxon test, at 5% significance level (α = 0.05). The OHI-S and GBI indices showed a significant reduction (p < 0.05) from the initial (1.4 ± 0.6 and 46.3 ± 19.9) to final condition (0.9 ± 0.3 and 21.5 ± 7.5). The decayed, missing and filled teeth and the missing teeth component were not significantly altered (p > 0.05), showing final values equal to 12.7 ± 9.6 and 5.6 ± 7.8, respectively. Decayed elements were fully converted into filled elements, and the final values of the decayed and filled elements were, respectively, 0.0 ± 0.0 and 7.3 ± 5.7 (p < 0.05). The enactment of the CDCP had a beneficial effect on the oral health of the population assisted by the dental services offered in primary care and this protocol seems to ft the public dental service demands. The CDCP can be useful to public dental service planning since it showed an efficient clinical outcome to the patients. We consider that this protocol should be employed in primary care oral health services in order to achieve overall upgrade, access enlargement and public oral health promotion.

Oral condition could be associated with cognitive impairment, but this is not yet well documented. We therefore hypothesized that people with poor oral condition would be more at risk to develop dementia. The objective of this study thus was to describe the oral condition of French community-dwelling elderly persons and to assess its relationship with the occurrence of dementia. Oral examination was conducted on a sample of individuals aged 66-80 years followed-up prospectively for screening of dementia over 15 years in Gironde, France. Univariate and multivariate analyses of the risk of dementia were performed using a Cox proportional hazard model with delayed entry. Data from 405 individuals were analyzed; 45.4% men; median age at baseline: 70 years [interquartile range (IQR): 68-75]. The median number of decayed, missing, and filled teeth was 18 (IQR: 13-24) and was higher in women (median: 20 versus 17, P = 0.004) and in persons with lower school level (median: 21 versus 17, P = 0.003). Among 348 persons with sextant eligible for periodontal assessment, 2/3 required periodontal care: 5.2% had bleeding observed, 44.8% calculus, 17.8% 4-5 mm pockets, and 2.9%≥ 6 mm pockets. The incidence of dementia during a median follow-up of 10 years (IQR: 6.5-13.7) was 19 per 1000 person-years. The adjusted hazard ratio for a number of missing teeth ≥ 11 (median) on the risk of dementia was 1.13 (95% confidence interval, CI = [0.60-2.12]) in people with higher education (n = 312) and 0.30 (CI = 0.11-0.79) in persons with lower school level (n = 93) (P for modification effect = 0.0002). Having eleven or more missing teeth seemed to be associated with a lower risk of dementia in people with lower education possibly owing to the suppression of source of chronic inflammation. © 2011 John Wiley & Sons A/S.

Screening the prevalence and pattern of dental identifiers contributes toward the process of human identification. This research investigated the uniqueness of clinical dental identifiers in photographs and radiographs. Panoramic and lateral cephalometric radiographs and five intra-oral photographs of 1727 subjects were used. In a target set, two observers examined different subjects. In a subset, both observers examined the same subjects (source set). The distance between source and target subjects was quantified for each identifier. The percentage of subjects in the target set being at least as close as the correct subject was assessed. The number of molars (34.6%), missing teeth (42%), and displaced teeth (59.9%) were the most unique identifiers in photographs and panoramic and lateral cephalometric radiographs, respectively. The pattern of rotated teeth (14.9%) was the most unique in photographs, while displaced teeth was in panoramic (37.6%) and lateral cephalometric (54.8%) radiographs. Morphological identifiers were the most unique, highlighting their importance for human identifications. © 2016 American Academy of Forensic Sciences.

Selective removal of esthetic composite restorations with spectral guided laser ablation

2016-02-01

Dental composites are used for a wide range of applications such as fillings for cavities, adhesives for orthodontic brackets, and closure of gaps (diastemas) between teeth by esthetic bonding. Anterior restorations are used to replace missing, diseased and unsightly tooth structure for both appearance and function. When these restorations must be replaced, they are difficult to remove mechanically without causing excessive removal or damage to enamel because dental composites are color matched to teeth. Previous studies have shown that CO2 lasers have high ablation selectivity and are well suited for removal of composite on occlusal surfaces while minimizing healthy tissue loss. A spectral feedback guidance system may be used to discriminate between dental composite and dental hard tissue for selective ablation of composite material. The removal of composite restorations filling diastemas is more challenging due to the esthetic concern for anterior teeth. The objective of this study is to determine if composite spanning a diastema between anterior teeth can be removed by spectral guided laser ablation at clinically relevant rates with minimal damage to peripheral healthy tissue and with higher selectivity than a high speed dental handpiece.

The impact of ebinyo, a form of dental mutilation, on the malocclusion status in Uganda.

Bataringaya, Aisha; Ferguson, Maurice; Lalloo, Ratilal

2005-09-01

The practice of extraction of ebinyo or false teeth is based on the belief that the rubbing of herbs on the gum (in the region of the canine) or the removal of the primary and/or permanent canine tooth buds will lead to the relief of childhood fevers and diarrhoea. The reported prevalence of this practice in Uganda and neighbouring countries is varied. A survey carried out in Kampala to determine the occlusal traits of fourteen-year-old children offered an opportunity to assess the effects of ebinyo (a dental mutilation based on local customs and superstitions) on the occlusal status of the sample population. 402 children aged fourteen years were examined according to the criteria of the Federation Dentaire Internationale Commission on Classification and Statistics for Oral Conditions method for measuring occlusal traits (COCSTOC-MOT) proposed by Baume et al. (1973). The most common dental anomaly was teeth missing due to extraction or trauma. Canines (28%) and mandibular first molars (28%) exhibited the highest frequency. Missing canines were four times more common in girls than boys, and three times greater in the maxilla than the mandible. Canines also accounted for 12.8% of the malformed teeth observed in the study. The results of this study show that the practice of ebinyo, although carried out early in the life of the child, can impact on the occlusal status in the permanent dentition years later.

This investigation studied the dental health status of a group of 184 Australian Aboriginal children with a mean age of 4.4 +/- 0.8 years, who were attending pre-schools in metropolitan Brisbane, a non-fluoridated state capital city. The DDE (Developmental Defects of Enamel) Index was used to chart enamel hypoplasia and enamel opacities. WHO criteria was used to diagnose dental caries. The results showed that 98% of children had at least one tooth showing developmental enamel defects. Each child had a mean of 3.8 +/- 1.7 teeth affected by enamel hypoplasia and another 1.1 +/- 0.8 teeth affected by enamel opacity. Seventy-eight percent of the children had dental caries. The mean number of decayed, missing, filled teeth (dmft) per child was 3.8 +/- 3.7. The decayed component constituted 3.5 (95%) of the mean dmft, indicating a high unmet restorative need in this group. The mean dmfs (decayed, missing, filled, surfaces) was 5.9 +/- 7.3. Maxillary anterior labial decay of at least one tooth affected 43 (23%) of the children. In this sub-group, the dmft and dmfs was 9.1 +/- 2.8 and 15.4 +/- 7.7 respectively. Oral debris was found in 98% of the children. It is hypothesized that the high levels of underlying developmental enamel defects, compounded by low fluoride exposure, poor oral hygiene and a diet high in refined sugars pose an important caries risk factor in this group of children.

Critical congenital heart disease (CCHD) screening is effective in asymptomatic late preterm and term newborn infants with a low false positive rate (0.035%). Objective (1) To compare 2817 NICU discharges before and after implementation of CCHD screening; and (2) to evaluate CCHD screening at < 35 weeks gestation. Methods collection of results of CCHD screening including preductal and postductal SpO2 values. Results During the pre-CCHD screen period, 1247 infants were discharged from the NICU and one case of CCHD was missed. After 3/1/12, 1508 CCHD screens were performed among 1570 discharges and no CCHDs were missed. The preductal and postductal SpO2 values were 98.8±1.4% and 99±1.3% respectively in preterm and 98.9±1.3% and 98.9±1.4% in term infants. Ten infants had false positive screens (10/1508=0.66%). Conclusions Performing universal screening in the NICU is feasible but is associated with a higher false positive rate compared to asymptomatic newborn infants. PMID:25058746

Hallerman-Streiff syndrome: case report and recommendations for dental care.

Hallerman-Streiff syndrome is a rare congenital anomaly characterized by a peculiar bird facies, mandibular and maxillary hypoplasia, dyscephaly, cataracts, microphtalmia, hypotrichosis, skin atrophy, and short stature. Dental abnormalities are present in 80 percent of the cases and include malocclusion, crowding, severe caries, supernumerary and neonatal teeth, enamel hypoplasia, hypodontia, premature eruption of primary dentition, agenesis of permanent teeth, and anterior displacement or absence of condyles. Very few cases have been described in the dental literature. The predisposition to severe caries, together with other problems, makes it imperative that young patients be started in a strong prevention program as early as possible. This is a case report of a five-year-eleven-month-old white male who presented for a dental examination at The Children's Hospital in Denver, CO. The findings and recommendations for treatment are discussed.

Oral Health-Related Quality of Life (OHRQoL) indicates an individual's perception of how their well-being and quality of life is influenced by oral health. It facilitates treatment planning, assessing patient centred treatment outcomes and satisfaction. The study aimed to identify the factors influencing OHRQoL among Tamil speaking South Indian adult population. Non-probability sampling was done and 199 subjects aged 20-70 years were recruited for this observational study. The subjects were requested to fill a survey form along with the validated Tamil General Oral Health Assessment Index (GOHAI-Tml) questionnaire in the waiting area following which clinical examination was done by a single experienced Periodontist. The mean score with standard deviation for physical dimension was 4.34±0.96, psychological dimension was 4.03±1.13 and pain was 4.05±1.09 on GOHAI. Greater impacts were seen for psychosocial dimensions like pleased with the appearance of teeth/denture Q7 (3.7±1.2), worried about the problems with teeth/denture Q9 (3.7±1) and pain or discomfort in teeth Q12 (3.8±1). Functions like swallowing Q3 (4.5±0.8) and speaking Q4 (4.6±0.7) were minimally affected. As age increased subjects perceived more negative impacts as indicated by lower ADD-GOHAI and higher SC-GOHAI scores (p<0.01). Subjects complaining of bad breath, bleeding gums and Temporomandibular Joint (TMJ) problems, reported poor OHRQoL (p<0.05). It was observed that as self-perceived oral and general health status deteriorated, OHRQoL also worsened (p<0.01). Subjects with missing teeth, cervical abrasion, restorations, gingival recession and mobility had more impacts on OHRQoL (p<0.05). Subjects diagnosed with periodontitis had lower OHRQoL as reported on the scale than gingivitis subjects (p<0.01). In this study minimal impact was seen in all the three dimensions assessed with GOHAI. Factors like age, education, employment status, income, self-reported oral health, self-perceived general health, satisfaction with oral health, perceived need for treatment and denture wearing status influenced perceived OHRQoL. Bad breath, bleeding gums, TMJ problems, more number of missing teeth, decayed teeth, cervical abrasion, gingival recession and mobility were associated with poor OHRQoL.

Missing data within the comprehensive geriatric assessment of the interRAI suite of assessment instruments potentially imply the under-detection of conditions that require care as well as the risk of biased statistical results. Impaired oral health in older individuals has to be registered accurately as it causes pain and discomfort and is related to the general health status. This study was based on interRAI-Home Care (HC) baseline data from 7590 subjects (mean age 81.2 years, SD 6.9) in Belgium. It was investigated if missingness of the oral health-related items was associated with selected variables of general health. It was also determined if multiple imputation of missing data affected the associations between oral and general health. Multivariable logistic regression was used to determine if the prevalence of missingness in the oral health-related variables was associated with activities of daily life (ADLH), cognitive performance (CPS2) and depression (DRS). Associations between oral health and ADLH, CPS2 and DRS were determined, with missing data treated by 1. the complete-case technique and 2. by multiple imputation, and results were compared. The individual oral health-related variables had a similar proportion of missing values, ranging from 16.3% to 17.2%. The prevalence of missing data in all oral health-related variables was significantly associated with symptoms of depression (dental prosthesis use OR 1.66, CI 1.41-1.95; damaged teeth OR 1.74, CI 1.48-2.04; chewing problems OR 1.74, CI 1.47-2.05; dry mouth OR 1.65, CI 1.40-1.94). Missingness in damaged teeth (OR 1.27, CI 1.08-1.48), chewing problems (OR 1.22, CI 1.04-1.44) and dry mouth (OR 1.23, CI 1.05-1.44) occurred more frequently in cognitively impaired subjects. ADLH was not associated with the prevalence of missing data. When comparing the complete-case technique with the multiple imputation approach, nearly identical odds ratios characterized the associations between oral and general health. Cognitively impaired and depressive individuals had a higher risk of missing oral health-related information. Associations between oral health and ADLH, CPS2 and DRS were not influenced by multiple imputation of missing data. Further research should concentrate on the mechanisms that mediate the occurrence of missingness to develop preventative strategies.

Cleft lip and palate (CLP) is the most common orofacial congenital malformation in live births. CLP can occur individually or in combination with other congenital deformities. Affected patients experience a number of dental, aesthetic, speech, hearing, and psychological complications and have a higher incidence of severe dental conditions. The purpose of this study is to characterise the different types of dental anomalies that are frequently associated with CLP patients based on a literature survey. By literature survey, this study characterises the different types of dental anomalies that are frequently associated with cleft lip and palate patients. Common dental anomalies associated with CLP are supernumerary tooth, congenitally missing tooth, delayed tooth development, morphological anomalies in both deciduous and permanent dentition, delayed eruption of permanent maxillary incisors, microdontia, and abnormal tooth number. The incidence of certain dental anomalies is strongly correlated with Cleft lip and palate, a finding that is consistent with previous studies.

The overall rehabilitation of women in sex work is unfortunately limited most of the time only to moving them to another profession, but it should be focused on including health as an important factor. Factors that restrict regular dental care include misconceptions, dental fear and expense of dental care, unpleasant dental experiences, and socioeconomic factors, but such a direct correlation cannot be made in the case of such women. Until now, no study has been conducted related to the complete dentition status and treatment needs of women in sex work. The aim of our survey was to evaluate the dentition status and treatment needs among the brothel-based women engaged in sex work. A pilot study was conducted on 30 women and the final sample size was estimated to be 350. All the women were above 18 years old. Systematic random sampling method was followed after line listing of the brothels. The dentition status and treatment needs were recorded using the World Health Organization assessment form, 1997. The data collected were tabulated and analyzed using Statistical Package for the Social Sciences (SPSS), version 16.0. The Chi-squared test was carried out to check the association, and all p-values below 0.05 were considered to be statistically significant. The mean number of decayed teeth per person was 5.05 (±4.81), missing teeth per person was 0.96 ± 2.71, filled teeth per person was 0.04 (±0.34), and the mean of decayed missing filled permanent teeth per person was 6.05 (±5.84). There was a significant association between dental caries and age, using finger to clean the teeth, and not visiting the dentist. Due to different risk factors, such as diet, improper oral hygiene maintenance, and substance abuse, the overall dental health was found to be compromised in this population. Economic burden is an important factor that influences their attitude toward oral health and is likely to be inherited by their next generation also.

1997-10-01

This retrospective study focused on the frequency of tooth loss due to periodontal abscess among 42 patients who were treated by a single clinician over a 5- to 29-year period. A total of 114 patients were selected from the active periodontal recall schedule of a single periodontist at The University of Iowa College of Dentistry. The criteria for inclusion in the study included having a history of moderate to advanced periodontitis, being on 3 to 6 month recall periodontal maintenance care, and completion of active periodontal therapy prior to October 1987. Other parameters evaluated were age; gender; number of teeth present and missing at the initial, reevaluation, and last periodontal recall visit; initial periodontal prognosis; furcation involvement; non-surgical and surgical periodontal therapy; and reasons for tooth loss. Patients were grouped according to the number of teeth lost following active periodontal treatment into well-maintained (0 to 3), downhill (4 to 9), and extreme downhill (10 to 23) groups. Forty-two of the 114 patients were identified as having one or more periodontal abscesses. A total of 109 teeth were affected by periodontal abscess of which 49 (45%) teeth were lost and 60 (55%) were successfully maintained over an average of 12.5 years (5 to 29 years). More furcated teeth were lost than nonfurcated teeth and teeth given a hopeless prognosis were lost more consistently than those given a questionable prognosis in all groups. The frequency of periodontal abscess and tooth loss per patient was greater in the downhill and extreme downhill response groups than the well-maintained group. This suggests that teeth with a history of periodontal abscess can be treated and maintained for several years.

To determine the accuracy of ultrasound in the diagnosis of congenital abnormalities at the Aga Khan University Hospital, Karachi. The data of congenital abnormalities was obtained from the obstetrical database and medical records of all cases complicated by congenital abnormalities, delivering from January 2001 to December 2003 and was reviewed. Antenatal ultrasounds had been performed by operators with different level of experience. In addition this data was retrieved from the termination and Congenital anomaly register. A structured data collection form was used to collect information of different variables of interest. Congenital abnormalities, complicated 2.8% (n=170), of all deliveries, including all cases of termination of pregnancy, stillbirth and live births. Out of the total, 11.6% occurred in women above the age of 35 years. Consanguinity was found in 18.2% cases. Prenatal diagnosis was made in just under half of the cases (48.8%). Central nervous system and renal abnormalities were commonly diagnosed. However, facial defects, heart defects or skeletal defects were more commonly missed. Antenatal ultrasound successfully diagnosed foetal abnormalities in 48.8% of cases, and more than 90% Central Nervous system defects and renal abnormalities. In contrast about a quarter of Cardiac defects and none of the facial defects were detected. Based on these findings we recommend that the Sonologist should incorporate four chamber view of the heart and also look at the face carefully.

To determine the experience, prevalence and severity of dental caries as well as to establish the treatment needs and restorative care in adolescents and young adults. This cross-sectional study included 638 subjects 16-25 years old candidates to enter to state public university of San Luis Potosí, México. For caries detection was used the DMFT index (sum of decayed teeth + missing teeth + filled teeth in the permanent dentition). With DMFT index data were calculated the experience, the prevalence and the severity of caries. Also are reported the significant caries index (SiC), the treatment needs index (TNI) and the care index (CI). Statistical analysis was performed using nonparametric tests. The mean DMFT index was 4.24 ± 3.85, prevalence 76.5% and severity of 52.3% for DMFT > 3 and 26.2% for DMFT > 6. The SiC index was 8.7. The TNI was 43.0% and 52.8% CI. No variation was observed (p > 0.05) on the experience, prevalence and severity of caries by age. The component "filled teeth" showed differences by age (p < 0.05). Women had higher caries experience and severity than men (p < 0.05), equally "decay teeth" and "filled teeth" (p < 0.05). We observed high levels of experience, prevalence and severity of dental caries in this sample of adolescents and young adults. We found almost 40% of untreated caries lesions. We found some differences by sex.

This study aimed to explore the impact of gender, birth weight, maternal age, type of delivery, gestational age and feeding practices on the eruption of teeth in children with no underlying medical conditions or developmental defects in their first year of life. A cross-sectional observational study design was used. A primary healthcare setting in Riyadh, Saudi Arabia. All children in their first year of life attending a vaccination clinic (n=422) were included in the study. Infants with chronic childhood illnesses, those who were below the 5th percentile in height or weight, infants with congenital birth defects and chronic illnesses, infants who were born preterm and low birth weight infants were excluded from the study. The type of delivery, birth weight, age of mother, height and weight percentile for age (as plotted on the WHO growth chart for infants) and feeding practices were recorded by the examiner, and this was followed by a clinical examination to determine the presence or absence of each tooth. Regression models were developed to determine the effect of the different variables on the presence of primary teeth. There was a significant association between the weight percentile of the child (adjusted for age) and the number of erupted primary teeth, suggesting that heavier children have an earlier eruption of teeth. No association was observed between birth weight, height percentile for age or maternal age at the time of birth and the number of erupted primary teeth. Children who were exclusively breast fed were significantly more likely to have an erupted first primary tooth earlier than non-breastfed group. Breast feeding and the weight of the child may have an influence on the eruption of primary teeth in the first year of life. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2017.

The study aimed to assess conformity with Brazil's standard protocol for diagnostic and therapeutic practices in the management of congenital syphilis by pediatricians in public maternity hospitals. A cross-sectional study was conducted in 2015 with 41 pediatricians working in all the public maternity hospitals in Teresina, the capital of Piauí State, Northeast Brazil, through self-completed questionnaires. The study assessed the conformity of knowledge and practices according to the Brazilian Ministry of Health protocols. The study has made evident low access to training courses (54%) and insufficient knowledge of the case definition of congenital syphilis (42%) and rapid tests for syphilis (39%). Flaws were observed in the diagnostic workup and treatment of newborns. Requesting VDRL (88%) and correct treatment of neurosyphilis (88%) were the practices that showed the highest conformity with standard protocols. Low conformity with protocols leads to missed opportunities for identifying and adequately treating congenital syphilis. Based on the barriers identified in the study, better access to diagnostic and treatment protocols, improved recording on prenatal cards and hospital patient charts, availability of tests and medicines, and educational work with pregnant women should be urgently implemented, aiming to reverse the currently inadequate management of congenital syphilis and to curb its spread.

Dental disease is more extensive in adults with chronic kidney disease, but whether dental health and behaviors are associated with survival in the setting of hemodialysis is unknown. Prospective multinational cohort. 4,205 adults treated with long-term hemodialysis, 2010 to 2012 (Oral Diseases in Hemodialysis [ORAL-D] Study). Dental health as assessed by a standardized dental examination using World Health Organization guidelines and personal oral care, including edentulousness; decayed, missing, and filled teeth index; teeth brushing and flossing; and dental health consultation. All-cause and cardiovascular mortality at 12 months after dental assessment. Multivariable-adjusted Cox proportional hazards regression models fitted with shared frailty to account for clustering of mortality risk within countries. During a mean follow-up of 22.1 months, 942 deaths occurred, including 477 cardiovascular deaths. Edentulousness (adjusted HR, 1.29; 95% CI, 1.10-1.51) and decayed, missing, or filled teeth score ≥ 14 (adjusted HR, 1.70; 95% CI, 1.33-2.17) were associated with early all-cause mortality, while dental flossing, using mouthwash, brushing teeth daily, spending at least 2 minutes on oral hygiene daily, changing a toothbrush at least every 3 months, and visiting a dentist within the past 6 months (adjusted HRs of 0.52 [95% CI, 0.32-0.85], 0.79 [95% CI, 0.64-0.97], 0.76 [95% CI, 0.58-0.99], 0.84 [95% CI, 0.71-0.99], 0.79 [95% CI, 0.65-0.95], and 0.79 [95% CI, 0.65-0.96], respectively) were associated with better survival. Results for cardiovascular mortality were similar. Convenience sample of clinics. In adults treated with hemodialysis, poorer dental health was associated with early death, whereas preventive dental health practices were associated with longer survival.

The deleterious effect of cariogenic dietary patterns on tooth loss is well characterized, but the contribution of diet-borne systemic inflammation to loss of teeth remains uncharted. Recent efforts have unveiled a protective role of single nutrients to periodontal health. However, the assessment of overall diet as a modifiable risk factor for oral health remains elusive. Thus, the aim of this study was to assess the association between diet-borne systemic inflammation and tooth loss in a representative sample of the US adult non-institutionalized population. A cross-sectional analysis of a sample of participants of the 2009-2010 and 2011-2012 continuous NHANES receiving an oral exam and providing dietary recall data was performed. Dietary inflammatory potential was assessed by the Dietary Inflammatory Index (DII), a composite measure computed based on the association between nutrients and systemic pro-inflammatory cytokine levels. The outcome measure was prevalent tooth loss. Numbers of missing teeth were regressed across quartiles of the DII using multivariable linear regression models. 6887 eligible NHANES participants were included in the analysis; participants in the highest quartile of the DII index (pro-inflammatory diet) had an average [95% CI] of 0.84 [0.24, 1.45] additional more teeth lost as compared to those in the lowest quartile of DII (anti-inflammatory diet) (p = 0.015), after adjusting for known confounders. This significant association remained in subgroup analyses, including the lowest tertiles of energy-adjusted carbohydrate intake, and in persons aged ≥50 years. Adherence to an anti-inflammatory diet is associated with fewer missing teeth. These results suggest protective dietary patterns as a modifiable protective factor for tooth loss in the US adult population and support the incorporation of tooth loss prevention in the agenda of dietary public health interventions to prevent chronic inflammatory diseases.

Objective This study was conducted to understand how eating speed and oral health condition are associated with obesity in Japanese working men. Methods We studied a total of 863 men attending an annual medical checkup of the Japanese Maritime Self Defense Force in Sasebo City, Japan. Participants answered a questionnaire about their eating speed, and we examined their anthropometric status in terms of BMI, waist circumference, and oral health condition, especially periodontal disease and number of functional teeth. Multivariate logistic regression analyses adjusting for potential confounding variables were performed. Results The multivariate-adjusted odds ratio for waist circumference greater than 90 cm of the ‘very fast’ group compared to the ‘slow, very slow’ group was 5.22 (95% confidence interval 1.81–15.06) after adjusting for potential confounding factors. Individuals were more likely to have waist circumference greater than 90 cm if they had a larger ‘number of missing functional teeth’ (odds ratio 1.14; 95% confidence interval 1.01–1.28) and severe periodontal disease (odds ratio 2.74; 95% confidence interval, 1.46–5.13). Conclusion Eating speed, the number of missing functional teeth, and severe periodontal disease are associated independently with larger waist circumference. PMID:29669358

No auditory experience, no tinnitus: Lessons from subjects with congenital- and acquired single-sided deafness.

Recent studies have adopted the Bayesian brain model to explain the generation of tinnitus in subjects with auditory deafferentation. That is, as the human brain works in a Bayesian manner to reduce environmental uncertainty, missing auditory information due to hearing loss may cause auditory phantom percepts, i.e., tinnitus. This type of deafferentation-induced auditory phantom percept should be preceded by auditory experience because the fill-in phenomenon, namely tinnitus, is based upon auditory prediction and the resultant prediction error. For example, a recent animal study observed the absence of tinnitus in cats with congenital single-sided deafness (SSD; Eggermont and Kral, Hear Res 2016). However, no human studies have investigated the presence and characteristics of tinnitus in subjects with congenital SSD. Thus, the present study sought to reveal differences in the generation of tinnitus between subjects with congenital SSD and those with acquired SSD to evaluate the replicability of previous animal studies. This study enrolled 20 subjects with congenital SSD and 44 subjects with acquired SSD and examined the presence and characteristics of tinnitus in the groups. None of the 20 subjects with congenital SSD perceived tinnitus on the affected side, whereas 30 of 44 subjects with acquired SSD experienced tinnitus on the affected side. Additionally, there were significant positive correlations between tinnitus characteristics and the audiometric characteristics of the SSD. In accordance with the findings of the recent animal study, tinnitus was absent in subjects with congenital SSD, but relatively frequent in subjects with acquired SSD, which suggests that the development of tinnitus should be preceded by auditory experience. In other words, subjects with profound congenital peripheral deafferentation do not develop auditory phantom percepts because no auditory predictions are available from the Bayesian brain.

The aim of this study was to investigate the various events occurring in unsplinted implant restoration in posterior jaws during a period of 4 years. From August 2008 to April 2009, eight volunteers (three men and five women) who had two or more consecutively missing teeth received 20 implants in posterior maxillae and mandibles. Unsplinted single crowns were delivered to each implant. For the 4-year follow-up periods, patients were enrolled in a maintenance schedule at 1, 3, 6, 12, 24, 36 and 48 months. The data, including a questionnaire, radiography, mobility and probing were recorded on regular check-ups. A total of 20 implants in eight patients were followed up for 48 months, showing a 100% survival rate. Mean marginal bone loss around implants was 0.26 mm. Statistical analysis revealed insignificant correlation between metal-ceramic and zirconia-ceramic crowns and among implant lengths (8.5 mm, 10 mm and 11.5 mm). Mean probing depths were similar or insignificantly different, regardless of the materials used or length of implants. The most frequent complications, in decreasing order, were food impaction (65%) and porcelain chipping (45%), sensitivity (25%), pain (20%) and loose contact (15%). Compared with metal-ceramic crowns, zirconia-ceramic crowns showed more unfavorable cases of porcelain chipping (p=0.017), pain (p=0.007) and loose contact with an adjacent crown (p=0.031). Within the limits of the sample size, this study showed that unsplinted implant-supported single restorations to replace consecutive posterior missing teeth may function well.

Triple X syndrome (47,XXX) is a numerical chromosomal alteration that affects 1/1,000 women, in which the woman is born with an extra X chromosome. Some oral changes have been reported in the literature, as hypodontia, influence on deposition of crown enamel and discrepancies in cephalometric measurements. Other systemic complications may lead to oral abnormalities similar to those seen in triple X patients, such as congenital hypothyroidism (CH). This paper reports a triple X syndrome case associated with CH later treated. Besides delay in cognitive and intellectual development, the patient had changes in teeth development and in cephalometric measurements with deficiencies in the maxilla and mandible. This is the first report of a triple X syndrome associated with CH. Both conditions may result in changes in dentofacial development. © 2013 Special Care Dentistry Association and Wiley Periodicals, Inc.

An antibiotic prophylaxis of infective endocarditis is recommended in patients at high risk for infective endocarditis (patients with valvular prosthesis, or cyanogen congenital or obstructive cardiac defect) or those with aortic, mitral or tricuspid valvulopathy, a non-cyanogen congenital or obstructive cardiac defect. Dental procedures (except treatment for superficial decay and preparation for the fitting of prostheses to teeth with intact pulp) are to be carried out under local antisepsis and a prophylactic antibiotics, such as 3 g of oral amoxicillin or in case of allergy to penicillin, 600 mg of clindamycin or 1g of pristinamycin, administered one hour prior to the procedure. A similar prophylaxis is recommended for the procedures on the upper respiratory tract. Amoxicillin, or vancomycin or teicoplanin are recommended for procedures under general anaesthesia. For surgery on the intestinal or urogenital tract, regimens combine amoxicillin with gentamicin, or in case of allergy to penicillin, vancomycin or teicoplanin with gentamicin.

To compare the stress distribution in abutment teeth and related tissues under the same material and different loading between improved major connector design and traditional major connector design. One 55-year-old male patient with unilateral maxillary first molar and second molar missing was chosen. The stress distribution in abutment teeth and related tissues were evaluated with spiral CT scanning, Mimics, Geomagic Studio software, a study model was built and finite element analysis was performed using ANSYS software. With the improved major connector design, the stress of abutment decreased significantly, the stress of periodontal decreased, the stress of edentulous mucosa increased significantly and became more balanced, the trend of stimulated absorption of alveolar bone decreased. For patients with distal free defect of dentition, the design of improved major connector has the effect of stress interruption, can protect the abutment better, detract the stress of the denture and has an good protective effect on the edentulous mucosa and alveolar bone.

In order to assess by periodontal evaluation the changes that might occur with time in the abutment teeth and periodontal tissues when Konus-Telescope dentures are used as that final treatment of periodontal disease, the dentures (15 units) were placed in 13 patients with missing tooth and periodontal disease and findings at the time of denture placement and 30 months after the placement were compared. The number of cases that exhibited significant changes in hygiene level, tissue inflammation and periodontal pocket depth of the abutment teeth after 30 months was very small, while as many as 85.2% of the abutment teeth showed decrease in tooth mobility. Increase in tooth mobility was not detected in any of the cases. In addition, X-ray examination revealed tendencies toward improvement of the periodontal ligament and remission of alveolar bone resorption in many of the cases. These results suggest that Konus-Telescope denture is highly offers protection of the residual periodontal tissues through its secondary splint action.

This paper aims to explore prisoner dental health in Haryana, India. The authors assessed the prevalence of dental caries and the treatment needs of prisoners in all 19 prisons in Haryana. The results were compared with the prison populations of other countries and the general population of Haryana. The mean age of 1,393 subjects examined was 35.26±12.29 years. A large number of the subjects reported to be in need of dental treatment. The number of decayed teeth was found to be similar to the general population of Haryana but the number of filled teeth was quite low. The number of teeth missing and the need for tooth extraction was high. Social implications - Long-standing prisoner dental problems indicated a need for dental treatment in prisons. This is the first study of its kind covering all 19 prisons in Haryana, India. The results indicate that the government needs to further consider and address the oral health needs of prisoners.

Ectodermal dysplasia (ED) refers to a group of inherited diseases that have developmental defects in at least two major structures derived from the ectoderm, that is, hair, teeth, nails and sweat glands. Although more than 192 distinct disorders have been described, the most common is X-linked recessive hypohidrotic ED (Christ-Siemens-Touraine syndrome). Since such patients usually presents with missing teeth, dentists are usually the first person to diagnose such cases. Diagnosis of such cases is important because absence of sweat glands can lead to hyperthermia which can be life-threatening if proper care is not taken. Through this manuscript, we report a case of anhidrotic ED affecting deciduous and permanent dentition, which is rare. PMID:24493109

Background This study’s objective was to develop a risk model incorporating procedure type and patient factors to be used for case-mix adjustment in the analysis of hospital-specific operative mortality rates after congenital cardiac operations. Methods Included were patients of all ages undergoing cardiac operations, with or without cardiopulmonary bypass, at centers participating in The Society of Thoracic Surgeons Congenital Heart Surgery Database during January 1, 2010, to December 31, 2013. Excluded were isolated patent ductus arteriosus closures in patients weighing less than or equal to 2.5 kg, centers with more than 10% missing data, and patients with missing data for key variables. Data from the first 3.5 years were used for model development, and data from the last 0.5 year were used for assessing model discrimination and calibration. Potential risk factors were proposed based on expert consensus and selected after empirically comparing a variety of modeling options. Results The study cohort included 52,224 patients from 86 centers with 1,931 deaths (3.7%). Covariates included in the model were primary procedure, age, weight, and 11 additional patient factors reflecting acuity status and comorbidities. The C statistic in the validation sample was 0.858. Plots of observed-vs-expected mortality rates revealed good calibration overall and within subgroups, except for a slight overestimation of risk in the highest decile of predicted risk. Removing patient preoperative factors from the model reduced the C statistic to 0.831 and affected the performance classification for 12 of 86 hospitals. Conclusions The risk model is well suited to adjust for case mix in the analysis and reporting of hospital-specific mortality for congenital heart operations. Inclusion of patient factors added useful discriminatory power and reduced bias in the calculation of hospital-specific mortality metrics. PMID:26245502

Traditionally, healing after surgical endodontic retreatment (SER); i.e. apicectomy with or without a retrograde filling, is assessed in periapical radiographs (PR). Recently, the use of cone beam CT (CBCT) has increased within endodontics. Generally, CBCT detects more periapical lesions than PR, but basic research on the true nature of these lesions is missing. The objective was to assess the diagnostic validity of PR and CBCT for determining inflammation in SER cases that were re-operated (SER-R) due to unsuccessful healing, using histology of the periapical lesion as reference for inflammation. Records from 149 patients, receiving SER 2004-10, were screened. In total 108 patients (119 teeth) were recalled for clinical follow-up examination, PR and CBCT, of which 74 patients (83 teeth) participated. Three observers assessed PR and CBCT as "successful healing" or "unsuccessful healing" using Rud and Molven's criteria. SER-R was offered to all non-healed teeth with expected favourable prognosis for subsequent functional retention. During SER-R, biopsy was performed and histopathology verified whether or not inflammation was present. All re-operated cases were assessed non-healed in CBCT while 11 of these were assessed successfully healed in PR. Nineteen biopsies were examined. Histopathologic diagnosis revealed 42% (teeth = 8) without periapical inflammation, 16% (teeth = 3) with mild inflammation and 42% (teeth = 8) with moderate to intense inflammation. A correct diagnosis was obtained in 58% with CBCT (true positives) and 63% with PR (true positives+true negatives). Of the re-operated teeth, 42% had no periapical inflammatory lesion, and hence no benefit from SER-R. Not all lesions observed in CBCT represented periapical inflammatory lesions.

There have been claims that dental caries experience and prevalence in Kenya has been increasing as a result of increased sugar consumption. A review of the literature in 1986 failed to link dental caries experience with an increase in gross national sugar consumption. Subsequently, a number of studies were conducted, necessitating further review to examine trends in dental caries experience and to relate this to changes in per capita sugar consumption. Studies conducted since 1980 for children 3-15 years of age were examined. Dental caries prevalence and experience for 3-5 years' (deciduous teeth) and 12 years' (permanent teeth) age groups were analysed. Calculation of per capita sugar consumption was performed using gross national annual sugar consumption for 1969-2009 national population census years. There was a gradual increase in per capita sugar consumption, from 35.5 g/day in 1969 to 60.8 g/day in 2009. Dental caries experience in deciduous teeth for children 3-5 years of age increased from a decayed, missing and filled teeth/decayed and filled teeth (dmft/dft) index of 1.5 in the 1980s to 2.95 in the 2000s. At 12 years of age, caries experience for permanent teeth increased from a DMFT of 0.2 to a DMFT of 0.92 over the same period. Dental caries prevalence for both deciduous and permanent teeth also increased with time. These observations suggest that dental caries prevalence and experience increased with time, in parallel to an increase in per capita sugar consumption. However, a clearer understanding can be derived from longitudinal studies, based on actual household age-specific sugar consumption and dental caries incidence. © 2016 FDI World Dental Federation.

Introduction Oral Health-Related Quality of Life (OHRQoL) indicates an individual’s perception of how their well-being and quality of life is influenced by oral health. It facilitates treatment planning, assessing patient centred treatment outcomes and satisfaction. Aim The study aimed to identify the factors influencing OHRQoL among Tamil speaking South Indian adult population. Materials and Methods Non-probability sampling was done and 199 subjects aged 20-70 years were recruited for this observational study. The subjects were requested to fill a survey form along with the validated Tamil General Oral Health Assessment Index (GOHAI-Tml) questionnaire in the waiting area following which clinical examination was done by a single experienced Periodontist. Results The mean score with standard deviation for physical dimension was 4.34±0.96, psychological dimension was 4.03±1.13 and pain was 4.05±1.09 on GOHAI. Greater impacts were seen for psychosocial dimensions like pleased with the appearance of teeth/denture Q7 (3.7±1.2), worried about the problems with teeth/denture Q9 (3.7±1) and pain or discomfort in teeth Q12 (3.8±1). Functions like swallowing Q3 (4.5±0.8) and speaking Q4 (4.6±0.7) were minimally affected. As age increased subjects perceived more negative impacts as indicated by lower ADD-GOHAI and higher SC-GOHAI scores (p<0.01). Subjects complaining of bad breath, bleeding gums and Temporomandibular Joint (TMJ) problems, reported poor OHRQoL (p<0.05). It was observed that as self-perceived oral and general health status deteriorated, OHRQoL also worsened (p<0.01). Subjects with missing teeth, cervical abrasion, restorations, gingival recession and mobility had more impacts on OHRQoL (p<0.05). Subjects diagnosed with periodontitis had lower OHRQoL as reported on the scale than gingivitis subjects (p<0.01). Conclusion In this study minimal impact was seen in all the three dimensions assessed with GOHAI. Factors like age, education, employment status, income, self-reported oral health, self-perceived general health, satisfaction with oral health, perceived need for treatment and denture wearing status influenced perceived OHRQoL. Bad breath, bleeding gums, TMJ problems, more number of missing teeth, decayed teeth, cervical abrasion, gingival recession and mobility were associated with poor OHRQoL. PMID:27891472

Abstract The aim of the study was to (a) analyse dental occlusion and determine the need for orthodontic treatment of persons with osteogenesis imperfecta (OI) in comparison with the healthy population and (b) investigate the associations between OI and malocclusion. A case‐control study included 26 OI persons and 400 healthy participants (control group). Occlusal features and the need for orthodontic treatment were defined according to Dental Health Component‐Index of Orthodontic Treatment Need and Dental Aesthetic Index. Results showed that Angle Class I, II, and III relationship was found in 23.1%, 3.8%, and 73.1% of OI group, and in the control group, it was 67%, 17.5%, and 15.5%, respectively. OI group had significantly higher prevalence of reverse overjet >1 mm (76.9%), missing teeth (42.3%), posterior crossbite (34.6%), and open bite >2 mm (19.2%) compared to the control group (8.5%, 2.2%, 6.2%, and 3.5%, respectively). OI group had less incisal segment crowding and more incisal segment spacing than the control group (p < 0.05). The need for orthodontic treatment of OI group according to Dental Health Component‐Index of Orthodontic Treatment Need and Dental Aesthetic Index was 88.5% and 61.5%, respectively, while in the control group, it was 24.8% and 51.8%. The malocclusion in OI persons was associated with reverse overjet > 1 mm (OR = 13.3, 95% CI = 3.9–44.7, p < .001), Angle Class III malocclusion (OR = 8.0, 95% CI = 2.0–30.8, p = .003), and missing teeth (OR = 4.7, 95% CI = 1.0–22.4, p = .049). In conclusion, there is the high probability of malocclusion in OI persons. Persons with OI require early orthodontic treatment because of significant correlation of OI disease with Angle Class III malocclusion, reverse overjet, and missing teeth. PMID:29744175

Cyanotic congenital heart disease and atherosclerosis.

2017-06-01

Improved treatment options in paediatric cardiology and congenital heart surgery have resulted in an ageing population of patients with cyanotic congenital heart disease (CCHD). The risk of acquired heart disease such as atherosclerosis increases with age.Previous studies have speculated whether patients with CCHD are protected against atherosclerosis. Results have shown that the coronary arteries of patients with CCHD are free from plaques and stenosis. Decreased carotid intima-media thickness and low total plasma cholesterol may indicate a reduced risk of later development of atherosclerosis. However, the evidence is still sparse and questionable, and a reasonable explanation for the decreased risk of developing atherosclerosis in patients with CCHD is still missing.This review provides an overview of what is known about the prevalence and potential causes of the reduced risk of atherosclerosis in patients with CCHD. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2017.

Current knowledge on dental anomalies in patients with incontinentia pigmenti (IP) has been obtained by examining case reports; however, an overall characterization of such alterations remains lacking. The objective of this study was to determine the frequency, type and location of dental alterations in IP using a case series. Fourteen patients (9 children and 5 adults) with a clinical diagnosis of IP who presented dental anomalies were included in this study. All patients were administered a clinical questionnaire, dental examination and radiological investigation. In the present case series, agenesis of primary dentition was present in 60 % of patients and agenesis of permanent tooth was present in 92.8 % of patients. Most cases were missing at least 6 teeth. Second molar agenesis was present in 13 patients (92.8 %). Anomalies in dental crowns occurred in 71.4 % of cases, and the central incisor was most frequently affected. Two adult patients still had primary teeth. Malocclusion was found in 10 patients (71.4 %). High-arched palate was observed in 7 (50 %) patients. Patients with IP present alterations in both primary and permanent dentition. Because the agenesis of permanent teeth is more common, primary teeth are not always replaced. In addition, the durability of primary dentition appears to be greater in IP. This study shows that patients with IP experience significant loss of teeth, especially in permanent dentition, and have an increased risk of high-arched palate compared to the general population. Prophylactic care of primary teeth in IP is relevant for improving functional and aesthetic outcomes until dental prostheses are implanted.

Very few studies have addressed long-term development and risks associated with untreated malocclusion. The purpose of this study was to examine changes in occlusion in a lifelong perspective and to compare oral health and attitudes toward teeth among persons with malocclusion with those having normal occlusion. In 1950 an epidemiologic survey of 2349 8-year-olds was conducted and included 4 intraoral photographs. Three selected samples with different malocclusions (deep bite, crossbite, or irregular teeth) and 1 sample with normal occlusion (a total of 183 subjects) were, 57 years later, invited for examination and an extensive interview about dental experiences and attitudes. Sixty-nine responded (38%) and constitute the subjects studied. Malocclusion remained the same or worsened except in subjects having deep bite in childhood, which in some improved and in others became worse. Crowding generally increased. Sixteen persons reported moderate or severe temporomandular joint (TMJ) problems, and of these 7 belonged to the group with crossbite in childhood. With few exceptions, the subjects in all samples had good oral hygiene, visited the dentist regularly, and had well-preserved dentitions. Mean number of missing teeth was significantly lower among those with normal occlusion compared with the malocclusion groups. Individuals with normal occlusion responded favorably to all questions related to attitudes and experiences about their teeth, while responses in the malocclusion groups varied. Persons with the particular malocclusions examined experienced more problems related to teeth later in life compared with those having normal occlusion in childhood.

Dental caries is frequently observed in children, particularly among those residing in developing countries. The most adapted strategies against this pathology remains prevention based on information, education, and communication (IEC), as well as on early diagnosis and treatment. We carried out a study that aimed to analyze the development of dental caries in a cohort of school children followed during their primary education. The objective was to assess the evolution of the dental status of a cohort of students during their elementary curriculum. A cohort of school children was followed during 6 years from the first grade to the sixth grade. Monitoring of these school children focused every year on IEC based on learning methods of brushing messages, dietary advice, systematic visits, fluoride use, and primary dental care. During the school year, the students were periodically subjected to education and communication briefings (IEC). Primary care consisted of extracting and descaling rhizalyzed teeth in the same period. The data from this review were collected using the World Health Organization questionnaire, and statistical analysis was performed with the software Epi-info version 6.04 d. The mean age of the 171 school children was 6 years in the first grade and 11 years in the sixth grade. In the first grade, the decayed permanent teeth prevalence was 31.6% and the In permanent teeth: Decayed, missing or filled teeth (DMF/T) was 0.47. The decayed primary teeth prevalence was 75% and the in primary teeth: decayed or filled teeth (df/t) 2.23. In the sixth year, the prevalence of decayed permanent teeth was 51% and DMF/T 0.36 whereas the decayed primary teeth prevalence was 12% and the df/t was 0.19. The prevalence of decayed permanent teeth increased from 31.6 to 51% whereas the mean DMF/T was not statistically different between school children of the first and sixth grade class. The promotion of oral health by IEC messages and monitoring of children constitute an effective preventive method for children's oral care.

Museum specimens (maxillae and/or mandibles) from 317 polar bears (Ursus maritimus) were examined macroscopically according to predefined criteria and 249 specimens were included in this study. The specimens were acquired between 1906 and 2011. There were 126 specimens (50.6%) from male animals, 93 (37.3%) from female animals and 30 (12.1%) from animals of unknown sex. The ages of the animals ranged from neonate to adult, with 125 adults (50.2%) and 124 young adults (49.8%) included and neonates/juveniles excluded from the study. The number of teeth available for examination was 7,638 (73.5%); 12.3% of teeth were absent artefactually, 0.8% were deemed absent due to acquired tooth loss and 13.4% were absent congenitally. With respect to tooth morphology, 20 teeth (0.26% of available teeth) in 18 specimens (7.2% of available specimens) were small vestigial structures with crowns that were flush with the level of surrounding alveolar bone. One supernumerary tooth and one tooth with enamel hypoplasia were encountered. Persistent deciduous teeth and teeth with an aberrant number of roots were not found. Relatively few teeth (3.7%) displayed attrition/abrasion, 90% of which were the maxillary and mandibular incisor teeth, in 41 polar bears (16.5%). Nearly twice as many adult specimens exhibited attrition/abrasion as those from young adults; significantly more males were affected than females. Dental fractures were noted in 52 polar bears, affecting 20.9% of specimens and 1.3% of the total number of teeth present. More adult polar bears had dental fractures than young adults. There were 21 specimens (8.4%) that displayed overt periapical disease, affecting a total of 24 dental alveoli (0.23%). Some degree of periodontitis was seen in 199 specimens (79.9%); however, only 12.6% of dental alveoli had bony changes indicative of periodontitis. Lesions consistent with temporomandibular joint osteoarthritis (TMJ-OA) were found in 23 specimens (9.2%). TMJ-OA was significantly more common in adults than in young adults and in males than in females. Although the clinical significance of dental and TMJ pathology in the polar bear remains elusive, the occurrence and severity of these lesions may play an important role in the morbidity and mortality of this species.

The authors describe a case of a congenital Mullerian anomaly, uterus unicornis with missing right fallopian tube. An in Vitro Fertilization Pre-Embryo Transfer (IVF-ET) procedure was done and presently is known that the patient has left fallopian tube and left ovary, two kidneys, and right ovary is missing. No diagnostic laparoscopy and hysteroscopy were done, only hysterosalpingography (HSG) before the IVF procedure. Several days after the follicular puncture of the left ovary the patient was urgently admitted to the hospital for specialized gynaecology in Varna. Transabdominal ultrasonography showed right ovary atypically located immediately next to the liver and with emerging theca-lutein cysts. PMID:27275261

Dental caries remains a public health problem even though it is preventable. There are several risk factors that relate to dental caries, especially in children in suburban and rural areas, where they normally receive their first dental examination in primary schools by teachers or health care personnel. Their oral health depends primarily on their parents' awareness. To identify prevalence and severity of dental caries and their risk factors among children in public education centers in Phranakornsriayudhya, Thailand. A cross-sectional total study was conducted among children attending public education centers in Koh-Rean Subdistrict, Phranakornsriayudhya District, Phranakornsriayudhya Province, Thailand including a day care center, 2 kindergartens and 2 elementary schools, during the academic year of 2005. All children were invited to attend a dental health survey including general oral examination and a face to face interview for the participants' parents as well as children attending grade 1-6. Standardized questionnaires were used to identify the participants' oral health care behaviors. There were 157 (99.4%) from 158 children aged 2-12 years participated in the survey, 152 (96.8%) students had dental caries. The prevalence of dental caries among pre-school children was 95.4%. The overall average Decay Missing Filling for primary teeth (dmft) was 7.4 (+/- 4.6) and the overall average Decay Missing Filling for permanent teeth (DMFT) was 3.7 (+/- 1.8). The dmft among pre-school children was 9.1 (+/- 5.2). The prevalence of gingivitis was 95.5%. The independence risk factors for dental caries for primary teeth were brushing under supervision of teacher when compared with the parents (Odds ratio = 12.1 (95% CI, 2.6-55.4)), and not brushing after breakfast (Odds ratio = 3.7 (95% CI, 1.1-12.1). There were no significant risk factors of dental caries for permanent teeth. A relatively high prevalence of dental caries was observed among children in suburban area in Thailand, especially in early childhood. It was shown that having the parents supervising their tooth brushing and having tooth brushing after breakfast may protect the dental caries for primary teeth. The public health interventions among this population are therefore urgently needed.

The Return of Congenital Rickets, Are We Missing Occult Cases?

Elidrissy, Abdelwahab T H

Congenital rickets is the term given to fetus born with clinical features of rickets, but those born with biochemical evidence of rickets without obvious clinical features still can be considered occult congenital rickets. Some of the affected babies with this disease have the intrauterine rachitic environment, but a calcium trans-placental pump prevents the fetus from having clinical features of rickets. They may present with hypocalcemia few days after birth or later with more florid features of rickets. Congenital rickets cases born with florid features reported over the last 40 years are few and can be divided into two groups. The first due to severe maternal osteomalacia in which their bones were so decalcified to have enough calcium to be pumped to their fetus. Another group in which newborn babies were hypocalcemic due to other maternal diseases as malabsorption, celiac disease, pre-eclampsia, and prematurity. All inherited rickets cases per se, or as part of other syndromes can be considered congenital rickets. Most cases seen in our region are due to maternal vitamin D deficiency with symptoms becoming obvious when the infants are breastfed, or may present with hypocalcemic convulsions or craniotabes. This is a review of congenital rickets with the aim of shedding light on this potentially acute disease that needs more attention and awareness in the neonatal period to avoid rare serious complications as cardiomyopathy or myelofibrosis and the complications of hypocalcemic convulsions. Congenital rickets cases seen simulate a tip of an ice-burg and its prevention is an important issue, especially with the tremendous urbanization with tall buildings living in sun-deprived flats as the commonest type of residence leading to the increasing incidence of maternal osteomalacia and rickets.

Patients with congenital haemophilia with inhibitors or acquired haemophilia are at risk of bleeding complications during surgery. In these patients, replacement therapy for the missing coagulation factor is ineffective, and a bypassing agent such as recombinant activated factor VII (rFVIIa) is required to manage bleeding. To evaluate the safety and haemostatic efficacy of rFVIIa treatment in Japanese patients with congenital haemophilia with inhibitors to FVIII/FIX or acquired haemophilia undergoing surgery. Postmarketing surveillance data from May 2000 to March 2010 were analysed to assess the haemostatic efficacy of 38 procedures in 22 patients with congenital haemophilia A, 13 procedures in seven patients with congenital haemophilia B, and five procedures in five patients with acquired haemophilia. Postoperative bleeding control was judged to be effective (bleeding was stopped completely or reduced considerably) for 34/38 procedures (89%) in patients with congenital haemophilia A, 10/13 procedures (77%) in patients with congenital haemophilia B, and 4/5 procedures (80%) in patients with acquired haemophilia. Tranexamic acid was used concomitantly for 36/56 procedures (64%). Safety was analysed for 66 procedures in 37 patients. Adverse effects potentially related to rFVIIa treatment included mild superficial thrombophlebitis, mild decrease in platelet count, and mild elevation of the serum alanine transaminase level in one patient each. All adverse effects resolved without treatment. Administration of rFVIIa provided adequate haemostasis without serious adverse effects in the majority of cases. The efficacy and safety data in Japanese patients were similar to previously published data from other countries. © 2014 The Authors. Haemophilia Published by John Wiley & Sons Ltd.

This study aimed to confirm the association between the community water fluoridation (CWF) programme and dental caries prevention on permanent teeth, comparing to a control area, neighbouring population without the programme, and verifying whether the programme can reduce the socio-economic inequality related to the oral health of children in Korea. Evaluation surveys were conducted among 6-, 8-, and 11-year-old children living in Okcheon (CWF) and neighbouring Yeongdong (non-CWF, control area) towns in South Korea. Data on monthly family income, caregiver educational level, and Family Affluence Scale scores were evaluated using questionnaires that were distributed to the parents. The effectiveness of CWF in caries reduction was calculated based on the differences in decayed, missing, and filled teeth and decayed, missing, and filled tooth surfaces indices between the two towns. The data were analysed using logistic regression and univariate analysis of variance. Both 8- and 11-year-old children living in the CWF area had lower dental caries prevalence than those living in the non-CWF community. Differences in dental caries prevalence based on educational level were found in the control area but not in the CWF area. Socio-economic factor-related inequality in oral health were observed in the non-CWF community. Additionally, 8- and 11-year-old children living in the CWF area displayed lower dental caries prevalence in the pit-and-fissure and smooth surfaces than those living in the non-CWF community. These results suggest that CWF programmes are effective in the prevention of caries on permanent teeth and can reduce oral health inequalities among children. The implementation of CWF programmes should be sustained to overcome oral health inequalities due to socio-economic factors and improve children’s overall oral health. PMID:28608827

Data on monthly family income, caregiver educational level, and Family Affluence Scale scores were evaluated using questionnaires that were distributed to the parents. The effectiveness of CWF in caries reduction was calculated based on the differences in decayed, missing, and filled teeth and decayed, missing, and filled tooth surfaces indices between the two towns. The data were analysed using logistic regression and univariate analysis of variance. Both 8- and 11-year-old children living in the CWF area had lower dental caries prevalence than those living in the non-CWF community. Differences in dental caries prevalence based on educational level were found in the control area but not in the CWF area. Socio-economic factor-related inequality in oral health were observed in the non-CWF community. Additionally, 8- and 11-year-old children living in the CWF area displayed lower dental caries prevalence in the pit-and-fissure and smooth surfaces than those living in the non-CWF community. These results suggest that CWF programmes are effective in the prevention of caries on permanent teeth and can reduce oral health inequalities among children. The implementation of CWF programmes should be sustained to overcome oral health inequalities due to socio-economic factors and improve children's overall oral health.

The morphometric analysis of maxillary sinus was recently presented as a helpful instrument for sex determination. The aim of the present study was to examine the volume and surface of the fully dentate, partial, and complete edentulous maxillary sinus depending on the sex. Computed tomography data from 276 patients were imported in DICOM format via special virtual planning software, and surfaces (mm) and volumes (mm) of maxillary sinuses were measured. In sex-specific comparisons (women vs men), statistically significant differences for the mean maxillary sinus volume and surface were found between fully dentate (volume, 13,267.77 mm vs 16,623.17 mm, P < 0.0001; surface, 3480.05 mm vs 4100.83 mm, P < 0.0001) and partially edentulous (volume, 10,577.35 mm vs 14,608.10 mm, P = 0.0002; surface, 2980.11 mm vs 3797.42 mm, P < 0.0001) or complete edentulous sinuses (volume, 11,200.99 mm vs 15,382.29 mm, P < 0.0001; surface, 3118.32 mm vs 3877.25 mm, P < 0.0001). For males, the statistically different mean values were calculated between fully dentate and partially edentulous (volume, P = 0.0022; surface, P = 0.0048) maxillary sinuses. Between the sexes, no differences were only measured for female and male partially dentate fully edentulous sinuses (2 teeth missing) and between partially edentulous sinuses in women and men (1 teeth vs 2 teeth missing). With a corresponding software program, it is possible to analyze the maxillary sinus precisely. The dentition influences the volume and surface of the pneumatic maxillary sinus. Therefore, sex determination is possible by analysis of the maxillary sinus event through the increase in pneumatization.

To determine the prevalence of dental caries among disabled individuals attending special schools in Vhembe districts. A cross-sectional descriptive study was conducted from January to June 2012 among disabled individuals receiving special care in four specialised schools of Vhembe District. The research protocol had been approved by the Ethics Committee of the University of Limpopo, Polokwane Campus. Informed consent was obtained from the parents of the participants and from the respective school principals. Oral health examinations took place at the school under natural light, with participants seated on an ordinary chair/wheelchair. Dental caries examinations were carried out, using a mirror and wooden spatula in accordance with World Health Organisation (WHO) criteria and methods. Decayed, missing and filled primary and permanent teeth (dmft, DMFT) were recorded. All disabled individuals who were available during a screening period, were included. Those who were not available, as well as those whose health conditions could be compromised by dental examinations, were excluded. The number of decayed teeth ranged from 0-7 in children below 6 years, 0-12 in children below 11 years; and 0-17 among young adults. The mean decay scores and the numbers of missing teeth increased with age. Only 3 (0.04%) individuals had dental fillings. The mean dmft score of children under 6 years was 5.51 (+/- 2.1), ranging from zero to 8. The mean DMFT's of the 11-18 and 19 years and older groups were 7.38 (+/- 3.22) and 10.24 (+/- 2.97) respectively. Disabled individuals exhibited higher caries prevalence and unmet dental needs than the same age general population in Limpopo. Preventive measures and dental treatment should be considered urgent requirements at special needs schools in the Vhembe District.

We evaluated the association between oral health and mortality. The study population comprised 76,188 subjects aged 16-89 years at recruitment. The mean follow-up time was 3.4 ± 2.4 years. Subjects with a personal medical history of cancer or cardiovascular disease and death by casualty were excluded from the analysis. A full-mouth clinical examination was performed in order to assess dental plaque, dental calculus and gingival inflammation. The number of teeth and functional masticatory units <5 were recorded. Causes of death were ascertained from death certificates. Mortality risk was evaluated using Cox regression model with propensity score calibrated for each oral exposure. All-cause mortality risk were raised with dental plaque, gingival inflammation, >10 missing teeth and functional masticatory units <5. All-cancer mortality was positively associated with dental plaque and gingival inflammation. Non-cardiovascular and non-cancer mortality were also positively associated with high dental plaque (HR = 3.30, [95% CI: 1.76-6.17]), high gingival inflammation (HR = 2.86, [95% CI: 1.71-4.79]), >10 missing teeth (HR = 2.31, [95% CI: 1.40-3.82]) and functional masticatory units <5 (HR = 2.40 [95% CI 1.55-3.73]). Moreover, when ≥3 oral diseases were cumulated in the model, the risk increased for all-cause mortality (HR = 3.39, [95% CI: 2.51-5.42]), all-cancer mortality (HR = 3.59, [95% CI: 1.23-10.05]) and non-cardiovascular and non-cancer mortality (HR = 4.71, [95% CI: 1.74-12.7]). The present study indicates a postive linear association between oral health and mortality.

Parafunctions (harmful habits) play a crucial role in the formation of temporo-mandibular joint (TMJ) dysfunction syndrome with disc displacement. Disorder symptoms in temporo-mandibular joints manifest themselves in the eye and ear but are usually not associated with the dysfunction of temporo-mandibular joints and that might lead to errors in diagnosis. The aim of the study was to examine the influence of missing teeth and parafunctions on the occurrence of ear and eye symptoms in patients treated in the Department of Prosthodontics of the Medical University of Lublin. The patient group consisted of 753 women and 253 men aged 10 to 82 years who had been treated in the Department of Prosthodontics, Medical University of Lublin in the years 2003-2008 due to various symptoms associated with temporo-mandibular joint dysfunction. Eye (24.84%, n = 785) and ear (33.38%, n = 785) syndromes occur on average more often in patients with parafunctions than without them (15.98%, n = 219 and 23.29%, n = 219). However, only parafunctions involving tooth contact should be taken into consideration when diagnosing eye and ear syndromes. The data presented here show that the number of missing teeth does not have a significant influence on the frequency of occurrence of parafunctions. Parafunctions have become a very important factor in the diagnosis of diseases and pathological symptoms of eye and ear as the rate at which they occur is growing. The kind of parafunction is very important. Only those involving tooth contact should be taken into consideration when diagnosing eye and ear syndromes.

It is known that fluoridation has a contextual effect on oral health socioeconomic inequalities, but broad public policies have not been investigated. Thus, the aim of this study was to determine the effects of municipal public policies on oral health across different social strata. This was a cross-sectional study with 7328 12-year-old children and 5445 15-19-year-old adolescents from 177 Brazilian municipalities. Information at municipal level was collated for dental services, educational services, sanitation and water fluoridation. The main individual-level exposure was the disposable equivalent household income. The dichotomous outcomes were as follows: untreated dental caries (≥1 tooth), missing teeth (≥1 tooth) and filled teeth (≥1 tooth). Analyses were carried out using multilevel logistic regression. Interaction terms were tested between individual-level income and policy variables. The prevalence of untreated dental caries, missing and filled teeth was 47.0%, 15.1% and 47.5%, respectively. There was no significant interaction between income and policy indicators. Individuals living in municipalities with no water fluoridation had 1.42 (95% CI: 1.08-1.86) higher odds of having untreated dental caries; the odds ratio (OR) for those in municipalities with less education policies was 1.36 (95% CI: 1.07-1.73); those in municipalities with less sanitation had OR = 1.05 (95% CI: 0.78-1.40); and those in municipalities with less dental care had OR = 1.36 (95% CI: 1.02-1.80). Fluoridation and policies about sanitation, education and dental care were similarly associated with oral health in different social strata. Other policies on social and economic fields may be further explored. © 2017 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

Every year millions of people seek dental treatment to either repair damaged, unaesthetic and dysfunctional teeth or replace missing natural teeth. Several dental materials have been developed to meet the stringent requirements in terms of mechanical properties, aesthetics and chemical durability in the oral environment. Glass-ceramics exhibit a suitable combination of these properties for dental restorations. This research is focused on the assessment of the thermomechanical behavior of bio-ceramics and particularly lithium aluminosilicate glass-ceramics (LAS glass-ceramics). Specifically, methodologies based on Infrared Thermography (IRT) have been applied in order the structure - property relationship to be evaluated. Non-crystallized, partially crystallized and fully crystallized glass-ceramic samples have been non-destructively assessed in order their thermo-mechanical behavior to be associated with their micro-structural features.

Occlusion for implant-supported fixed dental prostheses in partially edentulous patients: a literature review and current concepts

PubMed Central

2013-01-01

Implant treatment has become the treatment of choice to replace missing teeth in partially edentulous areas. Dental implants present different biological and biomechanical characteristics than natural teeth. Occlusion is considered to be one of the most important factors contributing to implant success. Most literature on implant occlusal concepts is based on expert opinion, anecdotal experiences, in vitro and animal studies, and only limited clinical research. Furthermore, scientific literature regarding implant occlusion, particularly in implant-supported fixed dental prostheses remains controversial. In this study, the current status of implant occlusion was reviewed and discussed. Further randomized clinical research to investigate the correlation between implant occlusion, the implant success rate, and its risk factors is warranted to determine best clinical practices.

To establish the levels of dental caries, bacterial dental plaque, gingivitis and caries-related microflora in children with glycogen storage disease (GSD). Patients with GSD are treated with regular intakes of glucose polymer and uncooked cornstarch to prevent hypoglycaemia. Dental health data are scarce. The study group comprised 21 children with GSD attending the Great Ormond Street Hospital for Children. These included the number of decayed, missing and filled teeth, and surfaces in both the primary and permanent dentitions, plaque and gingivitis scores. Both plaque and saliva were collected from each child and cultured for Mutans streptococci, Lactobacilli and Candida. The study group included 13 boys and eight girls, aged from 2.7 to 15.5 years. Four of the 21 children had some caries experience. The mean dmft was 0.5 and the mean DMFT, 0.06. Mean plaque and gingivitis scores were 4.8 and 5.9, respectively, for plaque and gingivitis adjacent to the primary teeth, and 11.6 and 12 for those related to permanent teeth. Only a small proportion of the children had caries experience but most were found to have plaque associated with both primary and permanent teeth. Preventive care should be targeted to improve plaque control thus minimizing the risk of developing periodontal disease as adults.

To assess intergenerational associations between dental caries and nutritional status, oral hygiene habits, and diet. A cross-sectional study was conducted with three generations of 54 families. Inclusion criteria were senior citizens with an adult son/daughter who also had a child (five to 12 years old). Dental caries was assessed using the decayed, missing, filled, primary teeth (dmft) and permanent teeth (DMFT) indexes. Nutritional status was evaluated using the body mass index (BMI), waist circumference, and percentage of body fat. Dietary habits, oral hygiene habits, and socioeconomic status were evaluated using a structured questionnaire. Children/adolescents with higher BMI had a lower dmft/DMFT index, and those who never or almost never consumed fruits and vegetables as snacks had a higher dmft/ DMFT index. When parents did not visit the dentist regularly, children/adolescents had more teeth affected by dental caries. When parents consumed sugar two or more times between meals, the number of affected teeth in children/adolescents increased. When children/ adolescents had a higher body mass index and they consumed fruits/vegetables as snacks more frequently, their caries experiences were lower. When their parents' did not visit the dentist regularly and they consumed sugar between meals more frequently, the children's caries experiences were higher.

To study the oral health and dental neglect of prenatally buprenorphine-exposed 3-year-old children. The study consisted of 51 children who as newborns tested positive for buprenorphine in a urine screen. The control group comprised 68 children previously unexposed to narcotics. The dentist examined the children and interviewed their guardians. Buprenorphine-exposed children exhibited significantly more early childhood caries than did the control group. Caries indices, the number of decayed, missing and filled teeth or tooth surfaces and decayed teeth were greater in the buprenorphine-exposed children than the control children (p = 0.004, p = 0.004, p = 0.001, respectively). In the buprenorphine group, more children showed visible plaque (p = 0.003) and fewer children were caries-free (p = 0.009) than in the control group. The control children's teeth were also brushed more often than the buprenorphine-exposed children's teeth (p = 0.001) and the parents were more involved in their children's tooth brushing than were those in the buprenorphine-exposed group (p = 0.035). More caries and dental neglect were found in buprenorphine-exposed children than in controls. These findings highlight the importance of routine dental appointments, caries screening and preventive care for children in substance-abusing families.

To report dental caries status, related health behaviours and social determinants among a representative sample of adults residing in Jerusalem. This cross-sectional study was conducted using a stratified sample of 254 Jewish and married adults aged 35-44 years in Jerusalem. Dental caries status was examined according to DMFT, percentage of caries-free persons and of people maintaining all their natural teeth (no teeth missing due to caries). The results were analysed by the independent variables and interpreted by weighted caries scores for the total Jerusalem population. The mean age was 38.63 years. Weighted DMFT was found to be 10.59; 6.8% of the population were caries-free; 67.1% demonstrated maintenance of all natural teeth. Level of education was the distal factor, associated with number of natural teeth, DMFT and untreated decay. Mediating behavioural determinants included dental attendance, plaque level and sugar consumption. The findings of this study demonstrated that caries experience among Jewish married adults in Jerusalem was moderate with low unmet dental caries needs. Additionally, data confirmed that a low level of education was a strong distal social determinant of caries experience, which affected dental health status via a pathway mediated by behavioural factors.

Dental caries continues to be the most common infectious disease of childhood; however, it is no longer pandemic, but endemic in specific sectors of populations. Therefore, it is important to identify and target patients at risk of developing caries in order to develop specific preventive measures. This study aims to test dental caries risk indicators for significant associations with caries severity. Five separate, small, isolated rural villages in Mexico with varying degrees of caries prevalence were selected for this observational study. A total of 248 children were examined. Risk indicators were assessed via questionnaire and water and salt fluoride analysis. Caries severity was measured by the International Caries Detection and Assessment System (ICDAS-I). Prevalence of caries ranged from 95% to 100% for the five villages. Mean total DMFS (decayed, missing, or filled surfaces-permanent teeth) and dmfs (decayed, missing, or filled surfaces-primary teeth) scores ranged from 2.5 to 5.0 and from 11.3 to 16.9, respectively. Multivariable models showed age and drinking soda between meals to be significantly associated with DMFS, and drinking juice and being female were significantly associated with dmfs. DMFS and dmfs were high in each village, significantly different between villages, and associated with specific risk indicators.

This study aimed to assess the potential association of periodontal diseases with lung volumes and airflow limitation in a general adult population. Based on a representative population sample of the Study of Health in Pomerania (SHIP), 1463 subjects aged 25-86 years were included. Periodontal status was assessed by clinical attachment loss (CAL), probing depth and number of missing teeth. Lung function was measured using spirometry, body plethysmography and diffusing capacity of the lung for carbon monoxide. Linear regression models using fractional polynomials were used to assess associations between periodontal disease and lung function. Fibrinogen and high-sensitivity C-reactive protein (hs-CRP) were evaluated as potential intermediate factors. After full adjustment for potential confounders mean CAL was significantly associated with variables of mobile dynamic and static lung volumes, airflow limitation and hyperinflation (p<0.05). Including fibrinogen and hs-CRP did not change coefficients of mean CAL; associations remained statistically significant. Mean CAL was not associated with total lung capacity and diffusing capacity of the lung for carbon monoxide. Associations were confirmed for mean probing depth, extent measures of CAL/probing depth and number of missing teeth. Periodontal disease was significantly associated with reduced lung volumes and airflow limitation in this general adult population sample. Systemic inflammation did not provide a mechanism linking both diseases.

Changing perspectives in screening for congenital hypothyroidism and congenital adrenal hyperplasia.

Mitchell, Marvin L; Hsu, Ho-Wen; Sahai, Inderneel

2014-02-01

The purpose of this review is to summarize recent information that has had a significant impact on the laboratory diagnosis and clinical management of newborns with congenital hypothyroidism and congenital adrenal hyperplasia (CAH). An approximate doubling of the incidence rate of congenital hypothyroidism in many parts of the world has been attributed to increased detection of infants with mild disease, delayed thyroid stimulating hormone elevations and demographic changes. A substantial number of children with modest thyroid stimulating hormone elevations on screening have permanent disease. Circulating levels of thyroxine may vary among hypothyroid children who are given identical dosages of medication. Treated infants should be monitored every 1-2 months during the first year of life. Although, generic and brand name thyroxine preparations may not be bioequivalent, children can be well controlled on generic formulations.Enzyme linked immunoassay assay for 17-hydroxyprogesterone is associated with a high rate of false positive specimens. In attempts to minimize this problem, some programs have resorted to two-tier screening of the initial specimen with steroid profiling as the second tier. Several programs are routinely testing second specimens in an effort to reduce the incidence of missed CAH cases. This review explains the uptick in incidence rate of congenital hypothyroidism and underscores issues in management that can affect developmental outcome. One specimen two-tier testing for CAH resulted in an increased false negative rate without significantly reducing the false positive rate. The benefit of collecting second specimens for CAH screening is problematic. Optimal treatment of CAH continues to pose a challenge.

To determine the effect of canine tooth characteristics and symmetry on perceived smile attractiveness when maxillary canine teeth are substituted for missing lateral incisors. Prospective, cross-sectional study. Non-clinical study undertaken from Leeds Dental Institute, UK. A composite full-face image of a smiling female was used to display various dentitions; a control image with an 'ideal' smile, plus six further images substituting the maxillary lateral incisors with canine teeth either unilaterally or bilaterally with varying size, shape, colour and gingival margin level. The seven images were shown to orthodontists (n = 30), dentists (n = 30) and lay people (n = 30) who were asked to rate smile attractiveness using a visual analogue scale. Dental professionals rated smiles with canine substitution for lateral incisor agenesis to be significantly less attractive than an ideal smile unless the substituted canine teeth approximated the lateral incisor in terms of size, shape, colour and gingival margin. Lay people did not find smiles where canine teeth were substituted for lateral incisors significantly more or less attractive than an ideal smile regardless of the canine tooth characteristics. Dental professionals were significantly more perceptive than lay people to the deviation from ideal smile aesthetics due to canine substitution. Smiles with unilateral canine substitution were not found to be significantly less attractive than bilateral canine substitution by all groups. Canine characteristics and observer status will affect how canine substitution for lateral incisor agenesis is viewed in terms of aesthetic outcome.

Do dentists have better oral health compared to general population: a study on oral health status and oral health behavior in Kathmandu, Nepal

PubMed Central

2014-01-01

Background Dentists are considered role models by the general population in regards to oral hygiene and oral health behavior. This study aimed to access the oral health status of dentists and laypersons, and compare the dentists’ practice of preventive dentistry and oral self-care behaviors to that of the laypersons. Methods This cross-sectional study recruited 472 participants (195 dentists and 277 laypersons from the general population). Their oral health/hygiene behavior was assessed using a standardized close-ended multiple choice questionnaire. Oral examination was performed to assess caries using Decayed Missed Filled teeth (DMFT) index and periodontal status using Community Periodontal Index of Treatment Needs (CPITN). Results Ninety-six percent of dentists brushed their teeth at least once daily, using fluoridated toothpaste and 80.5% twice daily. Although 94% of laypersons brushed their teeth once daily, they seldom used fluoridated toothpaste. Ten percent of participants in each group were caries free. The mean number of teeth present in the oral cavity (27.4 versus 25.4), mean number of teeth with caries (1.8 versus 3.7) and fillings (2.5 versus 0.4) were significantly different (p < 0.0001) between dentists and laypersons, respectively. Regarding the periodontal status, 82% of dentists had CPITN score of 0 whereas 71% of laypersons had the highest score 3 (p = 0.007), and 81% of the laypersons reported tooth mobility compared to 1% of dentists (p < 0.0001). Conclusions The participating dentists had better periodontal status and better self-reported oral health behaviors than the laypersons. Despite similar prevalence of caries in the two groups, the prevalence of decayed and unfilled teeth was lower among the dentists. PMID:24655533

The Effect of Multiple Sulfatase Deficiency (MSD) on Dental Development: Can We Use the Teeth as an Early Diagnostic Tool?

PubMed

Zilberman, Uri; Bibi, Haim

2016-01-01

Multiple sulfatase deficiency (MSD) is a rare autosomal recessive inborn error of metabolism due to reduced catalytic activity of the different sulfatase. Affected individuals show neurologic deterioration with mental retardation, skeletal anomalies, organomegaly, and skin changes as in X-linked ichthyosis. The only organ that was not examined in MSD patients is the dentition. To evaluate the effect of the metabolic error on dental development in a patient with the intermediate severe late-infantile form of MSD (S155P). Histological and chemical study were performed on three deciduous and five permanent teeth from MSD patient and pair-matched normal patients. Tooth germ size and enamel thickness were reduced in both deciduous and permanent MSD teeth, and the scalloping feature of the DEJ was missing in MSD teeth causing enamel to break off from the dentin. The mineral components in the enamel and dentin were different. The metabolic error insults the teeth in the stage of organogenesis in both the deciduous and permanent dentition. The end result is teeth with very sharp cusp tips, thin hypomineralized enamel, and exposed dentin due to the break off of enamel. These findings are different from all other types of MPS syndromes.Clinically the phenotype of intermediate severe late-infantile form of MSD appeared during the third year of life. In children of parents that are carriers, we can diagnose the disease as early as birth using X-ray radiograph of the anterior upper region or as early as 6-8 months when the first deciduous tooth erupt and consider very early treatment to ameliorate the symptoms.

Management of a child with severe hypodontia in the mixed dentition stage of development.

Severe hypodontia is a condition characterized by developmental absence of six or more teeth and affects 0.14-0.3% of the overall population. Hypodontia can have a marked psychosocial effect and functional implications for a growing child. A 10-year-old girl with a medical history of hypothyroidism and repaired spinal bifida was referred to the Leeds Dental Institute as she was becoming increasingly concerned about her appearance. On clinical examination, the patient had severe wear of her over-retained maxillary primary central incisors, microdontia of mandibular anterior teeth (32, 34, 41, 42, 43), and loss of anterior vertical dimension. Radiographic examination revealed that the patient had 11 missing permanent teeth (14, 13, 12, 11, 21, 22, 23, 24, 31, 35, 44), an ectopic mandibular left canine and taurodontism of the permanent molars. Management of the patient included an intensive preventive programme with placement of fissure sealants; scaling of calculus deposition on microdont teeth; composite resin reconstruction of microdont teeth; fabrication of removable partial overdentures tailored aesthetically to match the patient's age; orthodontic consultation and monitoring for the eruption of ectopic canine and permanent dentition. The patient and her parents reported marked improvement in self-esteem following dental treatment. After 2 years of follow-up, a new pair of dentures were made and designed to allow ease of eruption of the existing permanent dentition. All permanent teeth have erupted. The patient is ready for further assessment and planning for future orthodontic and restorative/implant treatment. This case illustrates the essential role of the paediatric dentist in the management of hypodontia in the mixed dentition stage.

This research compared the oral health status of school children in Dili (the capital of Timor Leste) in 2002 and 2014. The 2014 oral health survey of Dili's children replicated the methods of an AusAID-supported oral health survey conducted in 2002. Equal numbers of children were invited to participate from four age groups (6-8, 9-11, 12-14 and 15-17 years). For the 2014 survey, the subdistricts of Dom Aleixo, Cristo Rei, Metinaro and Vera Cruz were randomly selected for inclusion. A questionnaire was used to collect data on demographics and oral health behaviours. Oral epidemiological examinations were conducted by four dentists and five dental nurses. The 2014 survey in Dili recruited 758 participants for the questionnaire and 655 children for the oral examination. In 2014, a lower proportion of children reported brushing their teeth the previous day (97% vs 100%, p=0.01) and a larger proportion reported having toothache (40% vs 19%, p<0.001) (sometimes to very often) during the previous 12 months. The mean number of decayed, missing or filled teeth in the primary plus permanent dentition (dmft + DMFT) was greater in 2014 than in 2002 (4.2 vs 3.5, p=0.01). There was no difference in the prevalence of decay in the primary dentition (39% vs 37%, p=0.61) or the mean number of decayed, missing or filled (dmft) teeth in the primary dentition in 2014 compared to 2002 (2.0 vs 1.8, p=0.47). However, the prevalence of decay in the permanent dentition was greater in 2014 (70% vs 53%, p<0.001) as was the mean DMFT (2.3 vs 1.7, p=0.04). The prevalence of gingival bleeding (65% vs 81%, p<0.001) and calculus (57% vs 86%, p<0.001) was lower in 2014. There was an increase in dental caries experiences in Dili school children between 2002 and 2014, associated with more permanent teeth dental caries experiences.

Hallermann-Streiff syndrome associated with small cerebellum, endocrinopathy and increased chromosomal breakage.

Hallermann-Streiff syndrome (HSS) is a rare clinic entity of unknown aetiology. Further clinical and metabolic-genetic evaluations are indicated. A 2-mo-old female baby presented with ocular abnormalities and severe failure to thrive since birth. The clinical features were compatible with the diagnosis of HSS. Further imaging, metabolic and cytogenetic examinations were performed. Features characteristic of HSS were dyscephaly with mandibular and nasal cartilage hypoplasia, microphthalmia, bilateral cataracts with congenital glaucoma, natal teeth and proportionate dwarfism. Rare anomalies such as choanal atresia and small cerebellum, very low insulin-like growth factor I level, hypothyroidism, generalized organic aciduria were also noticed. An increased chromosomal breakage rate is suggestive of the existence of some DNA repair defects in HSS patients. The associated anomalies in this patient may broaden the clinical spectrum of HSS. Underlying conditions of organic aciduria, growth factor deficiency and impaired DNA repair are likely to contribute to the progeria-like facies, congenital cataracts and growth failure.

Malignant hyperthermia is a genetic defect of uncontrolled hypermetabolic skeletal muscle response to anesthetic triggering drugs. Some congenital myopathies are regarded as risk increasing factors. The use of volatile anaesthetics or suxamethonium (succinylcholine) in patients who are predisposed to malignant hyperthermia leads to an increase in Ca2+ release from sarcoplasmic reticulum, which in turn causes a set of biochemical and clinical symptoms, which can be a cause of death, if dantrolene is not administered adequately. The aim of the study was to draw attention to the problem of malignant hyperthermia, which is hardly ever described in Polish literature, and requires the necessity of intensifying the cooperation between the dentist and specialists from other medical fields. The origin of the article was a case of congenital myopathy with recognized malignant hyperthermia in an 18-year-old patient, in whom surgical extraction of teeth was indicated. The course of diagnostics and treatment showed once more that contemporary medicine is in need of holistic approach, and in consequence, promising and effective cooperation of many specialists.

Ectodermal dysplasia is a clinically and genetically heterogeneous group of inherited disorders characterized by abnormal development of two or more of the following ectodermal-derived structures: hair, teeth, nails and sweat glands. The hair is the most frequently affected structure. Hair shaft abnormalities are of great concern to these patients, but no effective treatments are available. We describe three girls with congenital hypotrichosis (9, 5 and 6 years old) caused by ectodermal dysplasia treated with topical cetirizine solution (2 mL. once daily) and oral vitamin D supplementation (1000 IU daily). After 6 months of treatment, the density of hair on the scalp increased in all patients. The vellus hair was replaced by terminal hair. Hair regrowth was evaluated both from the clinical and trichoscopic point of view. We propose a combination of topical cetirizine and oral vitamin D as a rational treatment of choice in congenital hypotrichosis caused by ectodermal dysplasia. © 2016 European Academy of Dermatology and Venereology.

Environmental lead (Pb) pollution is a global problem. Hard dental tissue is capable of accumulating lead and other hard metals from the environment. The aim of this study was to investigate any correlation between the concentration of lead in teeth extracted from inhabitants of Pancevo and Belgrade, Serbia, belonging to different age groups and occurrence of tooth loss, caries and non-carious lesions. A total of 160 volunteers were chosen consecutively from Pancevo (the experimental group) and Belgrade (the control group) and divided into 5 age subgroups of 32 subjects each. Clinical examination consisted of caries and hard dental tissue diagnostics. The Decayed Missing Filled Teeth (DMFT) Index and Significant Caries Index were calculated. Extracted teeth were freed of any organic residue by UV digestion and subjected to voltammetric analysis for the content of lead. The average DMFT scores in Pancevo (20.41) were higher than in Belgrade (16.52); in the patients aged 31-40 and 41-50 years the difference was significant (p < 0.05) and highly significant in the patients aged 51-60 (23.69 vs 18.5, p < 0.01). Non-carious lesions were diagnosed in 71 (44%) patients from Pancevo and 39 (24%) patients from Belgrade. The concentrations of Pb in extracted teeth in all the groups from Pancevo were statistically significantly (p < 0.05) higher than in all the groups from Belgrade. In the patients from Pancevo correlations between Pb concentration in extracted teeth and the number of extracted teeth, the number of carious lesions and the number of non-carious lesions showed a statistical significance (p < 0.001, p < 0.01 andp < 0.001, respectively). According to correlations between lead concentration and the number of extracted teeth, number of carious lesions and non-carious lesions found in the patients living in Pancevo, one possible cause of tooth loss and hard dental tissue damage could be a long-term environmental exposure to lead.

Three-dimensional echocardiographic evaluation of an incidental quadricuspid aortic valve.

Quadricuspid aortic valve is one of the rare forms of congenital cardiac valvular disease. Its diagnosis is often missed, even with the transthoracic echocardiogram. Many of these patients progress to aortic incompetence later in life requiring surgical intervention. In addition, quadricuspid aortic valve can be associated with other congenital cardiac deformities. Hence early recognition and follow-up is critical in these patients. We report a patient with quadricuspid aortic valve identified on intraoperative transesophageal 3-D echocardiography. This 66-year-old male presented with the features of congestive heart failure. The preoperative transthoracic echocardiogram (TTE) disclosed, moderately severe aortic valve insufficiency along with severe mitral and tricuspid regurgitation, but failed to reveal the quadricuspid anomaly of the aortic valve. Interestingly, this patient had undergone transthoracic echocardiography on two previous occasions during the past seven years for the evaluation of his valvular heart disease, which all failed to document this anomaly. Intraoperatively, transesophageal echocardiography (TEE) displayed an aortic valve composed of three medium and one small cusps. Our patient's case demonstrates the usefulness of transesophageal echocardiography in detection of this uncommon congenital malformation.

Ectodermal dysplasia is a rare congenital disease that affects the ectodermal structures. It is characterized by hypotrichosis, hypohidrosis and hypodontia. A 14-year-old boy with ectodermal dysplasia presenting with oligodontia and marked resorption of the maxillary and mandibular alveolar ridges is reported. Prosthetic rehabilitation in the form of a maxillary and mandibular partial denture was made with metal crowns on existing lower teeth to achieve appropriate vertical dimension. Significant improvement in speech, masticatory function and facial esthetics was achieved. Removable prosthodontics can provide an acceptable solution to esthetic, functional and psychological rehabilitation in patients with ectodermal dysplasia.

2017-12-01

The purpose of this retrospective longitudinal cohort study was to evaluate the outcome of nonsurgical root canal treatment (NSRCT), expressed as survival for both periapical health and retention of roots/teeth, as determined by clinical evaluation, periapical film/digital radiography (PFR/DPR), and cone-beam computed tomography (CBCT) over 10 years, to determine the prognostic factors that influenced successful treatment outcomes. A total of 132 teeth (208 roots) with vital pulp received NSRCT at a university clinic. Eighteen factors (preoperative, intraoperative, and postoperative) were documented from the dental records and radiographs. Periapical indices with scores ≥2 (PFR/DPR) and ≥1 (CBCT) indicated the presence of a periapical lesion. Data were analyzed using the Kaplan-Meier test and the Cox proportional hazards regression model (P < .05). The estimated 10-year overall survival rates for periapical health of roots/teeth were 89.4%/88.6% with PFR, 89.4%/89.3% with DPR, and 72.6%/69.7% with CBCT; the survival rate for root/tooth retention was 90.4%/91.6%. The long-term outcome of NSRCT expressed as survival for periapical health was different with each radiographic method. Approximately more than 90% of the roots/teeth were retained for up to 10 years. The prognostic factors for periapical health were the disinfection of gutta-percha, missed canals, age, treatment sessions, and density of root filling (voids); the age and presence of a post were for root/tooth retention.

Tooth damage as a result of oral stereotypies is evident in captive orca, yet little research on the topic exists. This study examines the associations between dental pathology, sex, facility, duration of captivity and other factors in captive orca. We evaluated mandibular and maxillary teeth from dental images of 29 captive orca owned by a US-based theme park. Each tooth was scored for coronal wear, wear at or below gum line and bore holes. Fractured and missing teeth were also noted. Summary statistics described the distribution and severity of pathologies; inferential statistics examined how pathologies differed between sexes, between wild-captured and captive-born orcas and between captive orca at four facilities. We also evaluated how dental pathology and duration of captivity were related. Approximately 24% of whales exhibited "major" to "extreme" mandibular coronal tooth wear, with coronal wear and wear at or below gum line highly correlated. More than 60% of mandibular teeth 2 and 3 exhibited fractures. Bore holes were observed primarily among anterior mandibular teeth, with more than 61% of teeth 2 and 3 bearing evidence of having been drilled. Four of five orca with the highest age-adjusted tooth pathology indices were captive-born. Various dental pathologies were observed across all whales, with pathologies beginning at a young age. Oral stereotypies exhibited by captive orca contributed to the observed dental damage. By making dental and health records of captive whales publicly available, the theme park industry is uniquely positioned to provide further insight into dental pathology and resultant health consequences in captive orca.

This cross-sectional study was aimed at determining whether certain pre-natal and natal conditions can predict specific dental anomalies. The conditions observed were: low birth-weight, preterm birth, pre-natal & natal complications. The dental anomalies observed were: enamel defects, total number of decayed, missing and filled teeth (total DMFT), disturbances in the tooth shape and disturbances in the number of teeth. Out of more than 2000 medical files of children aged 2-17 years old which were reviewed, 300 files met the selection criteria. Information recorded from the files included: age, gender, health status (the ASA physical status classification system by the American Society of Anesthesiologists), birth week, birth weight, total DMFT, hypomineralization, abnormal tooth shape, abnormal number of teeth and hypoplasia. Twenty one children out of 300 (7%) were born after a high-risk pregnancy, 25 children (8.3%) were born after high-risk birth, 20 children (6.7%) were born preterm - before week 37, and 29 children (9.7%) were born with a low birth weight (LBW) - 2500 grams or less. A relationship between a preterm birth and LBW to hypomineralization was found. And a relationship between a preterm birth and high-risk pregnancy to abnormal number of teeth was found. No relationship was found between birth (normal/high-risk) and the other parameters inspected. Preterm birth and LBW may predict hypomineralization in both primary and permanent dentitions. Furthermore, the study demonstrated that preterm birth and high-risk pregnancy may predict abnormal number of teeth in both dentitions.

Implant-retained overdentures for young children with severe oligodontia: a series of four cases.

2014-09-01

The treatment need is high in children with severe oligodontia and anodontia, because they often have functional and esthetic problems owing to missing teeth. Because the intraforaminal region barely grows after eruption of the permanent mandibular incisors, dental implant treatment should be considered a treatment option for these children. The purpose of our study was to assess the treatment outcomes regarding satisfaction and the care and aftercare of implant-retained mandibular overdentures in a series of 4 young children without erupted mandibular teeth from either severe oligodontia (n = 3) or anodontia (n = 1). Four children without erupted mandibular teeth, aged 6 to 13 years, were provided with an implant-retained overdenture on 2 implants. The surgical and prosthetic care and aftercare were scored by the clinicians. Also, the patients and their parents were queried about how satisfied they were with the overdenture. The median follow-up of the patients was 5.2 years (range 3.2 to 8.4). No implants were lost, no cases of peri-implantitis occurred, and the need for treatment and aftercare was low. Patient and parent satisfaction with this treatment was high. A 2-implant, retained overdenture in children with no erupted mandibular teeth is a safe treatment modality when appropriate treatment and aftercare can be provided.

2015-01-01

Forensic odontology is primarily concerned with the use of teeth and oral structures for identification in a legal context. Various forensic odontology techniques help in the identification of the human remains in incidents such as terrorists' attacks, airplane, train and road accidents, fires, mass murders, and natural disasters such as tsunamis, earth quakes and floods, etc. (Disaster Victim Identification-DVI). Dental structures are the hardest and well protected structures in the body. These structures resist decomposition and high temperatures and are among the last ones to disintegrate after death. The principal basis of the dental identification lies in the fact that no two oral cavities are alike and the teeth are unique to an individual. The dental evidence of the deceased recovered from the scene of crime/occurrence is compared with the ante-mortem records for identification. Dental features such as tooth morphology, variations in shape and size, restorations, pathologies, missing tooth, wear patterns, crowding of the teeth, colour and position of the tooth, rotations and other peculiar dental anomalies give every individual a unique identity. In absence of ante-mortem dental records for comparison, the teeth can help in the determination of age, sex, race/ethnicity, habits, occupations, etc. which can give further clues regarding the identity of the individuals. This piece of writing gives an overview of dental evidence, its use in forensic identification and its limitations.

In many parts of the world, school-age children have high dental treatment needs; however, there is often low, or no, dental care provision. Although Atraumatic Restorative Treatment (ART) was developed to address this, its survival rate in occluso-proximal lesions is low. An alternative, the Hall Technique (HT) has shown better relative outcomes for occluso-proximal lesions, but has not been directly compared to ART or tested in field settings. This trial will compare ART and the HT for the most clinically- and cost-effective strategy for managing occluso-proximal lesions in primary molars, in a school setting, using low-technology and child-friendly dental techniques. This two-arm, parallel group, patient-randomized controlled, superiority trial will have treatment provided in schools. Schoolchildren (n = 124, age 6-8) with at least one occluso-proximal carious primary molar lesion will have random allocation to treatment with ART or HT. Baseline measures and outcome data will be assessed through participant report, clinical examination and parent report/questionnaires. The primary outcome is survival rate, a composite measure of absence of Minor Failures (a defect in the restoration/crown, but not interfering with tooth health) and Major Failures (signs or symptoms of irreversible pulp damage, such as dental fistula/abscess, tooth fracture or failures that cannot be repaired). Secondary outcomes are: (1) child-reported discomfort, (2) childrens' and (3) parents' concerns around dental appearance and (4) acceptability of treatments, (5) occlusal-vertical dimensions (OVD) changes, (6) plaque index, (7) gingival health, (8) decayed, missing, filled teeth in permanent teeth (DMFT)/decayed, missing, filled teeth in primary teeth (dmft), (9) oral health-related-quality of life, reported by children and parents/caregivers, (10) the incremental cost-effectiveness, and (11) operator effect. A trained and calibrated examiner will evaluate the treated teeth after 1 week, then 1, 6, 12, 24 and 36 months post treatment. Kaplan-Meier and Cox regression tests will be used to investigate the primary outcome. The Mann-Whitney or t test, Friedman test, paired t test or Wilcoxon test and Ordinal Logistic Regression Analysis will be used to analyze the secondary outcomes. The results of this trial will support decision-making by clinicians and policy-makers for managing occluso-proximal lesions in settings with constrained resources and limited dental access. www.clinicaltrials.gov, NCT02569047 , registered 5 October 2015.

2006-07-01

The association of dental caries and diabetes mellitus has not received enough attention, in spite of the fact that both diseases are associated with the ingestion of dietary carbohydrates. This study was undertaken in Fars Province, southern Iran, to determine the prevalence rates of dental caries in a group of metabolically well-controlled patients with type I diabetes mellitus and in a control group. Fifty patients (22 boys and 28 girls) with type I diabetes mellitus under follow-up of the Endocrinology and Metabolism Research Center of Shiraz University of Medical Sciences, with a mean +/- SD age of 11.72 +/- 3.36 years and mean +/- SD fasting blood sugar of 235.74 +/- 103.61 mg/dL, entered this study. A similar study was conducted to determine the prevalence of dental caries in 12-year-old school children in Shiraz, Iran who served as the control group. After completing a questionnaire, the patients were examined separately by two dentists. Before the clinical examination, bitewing radiographies were performed. Student's t- and Chi-square tests were used for statistical analysis in relation to sex, age of onset of diabetes mellitus, socioeconomic and nutritional status, family history of diabetes mellitus, and orohygiene status. The mean +/- SD DMFT for diabetic children was 9.64 +/- 4.64 (decayed = 8.12 +/- 3.90, missing = 0.62 +/- 1.34, and filling = 0.90 +/- 2.10). The lower permanent first molars were the most frequency decayed and the incisors were the healthiest teeth. DMFT score and the frequency of decayed teeth were higher in boys than in girls. However, the rate of filling and missing teeth were higher in girls. DMFT and the number of decayed teeth were higher in patients with poor oral hygiene. The number of healthy first permanent molars was much higher in the mixed dentition groups than in those with permanent teeth. A direct correlation was found between the health status of the first permanent molar tooth and having type I diabetes mellitus. Oral hygiene was somewhat poorer in diabetic patients than in the control group. Regular dental check-ups for preventive measures such as fluoride therapy, fissure sealant, regular medical follow-ups for proper control of metabolic abnormalities to decrease occurrence of xerostomia, omission of cariogenic substances from dietary regimen, fluoridation of drinking water, and individual and group education of diabetic patients regarding proper dental hygiene are recommended.

Incidence of missed inferior alveolar nerve blocks in vital asymptomatic subjects and in patients with symptomatic irreversible pulpitis.

Fowler, Sara; Reader, Al; Beck, Mike

2015-05-01

The purpose of this retrospective study was to determine the incidence of missed inferior alveolar nerve (IAN) blocks by using a 1- or 2-cartridge volume of 2% lidocaine with 1:100,000 epinephrine in vital asymptomatic teeth and in emergency patients with symptomatic irreversible pulpitis. As part of 37 studies, 3169 subjects/patients were evaluated for missed IAN blocks. The study included 2450 asymptomatic subjects and 719 emergency patients presenting with symptomatic irreversible pulpitis. Each subject or patient received either a 1- or 2-cartridge volume of 2% lidocaine with 1:100,000 epinephrine. A missed block was defined as no lip numbness at 15-20 minutes after the IAN block. The effect of anesthetic volume on the incidence of missed blocks was assessed by using mixed models logistic regression with individual studies as a random effect. The incidence of missed blocks for asymptomatic subjects was 6.3% for the 1-cartridge volume and 3.8% for the 2-cartridge volume. For patients presenting with irreversible pulpitis, the incidence of missed blocks was 7.7% for the 1-cartridge volume and 2.3% for the 2-cartridge volume. In both asymptomatic subjects and patients with irreversible pulpitis, the 2-cartridge volume was significantly (P = .0395) better than the 1-cartridge volume. There were no significant effects for pulpal diagnosis (P = .7523) or the pulpal diagnosis and anesthetic volume interaction (P = .3973). Concerning missed IAN blocks, we concluded that administration of a 2-cartridge volume was significantly better (P = .0395) than a 1-cartridge volume in both asymptomatic subjects and emergency patients presenting with irreversible pulpitis.

2009-01-01

The widespread use of endosseous osseointegrated implants to replace missing natural teeth increases the chances of implant complications and failures, despite the high initial success rate reported in the literature. Implant fracture is one possible complication that results in ultimate failure of the dental implant. Such a complication poses a management crisis even for the most experienced clinician. This article reports on a case of implant fracture, its possible causes, and how the case was managed.

To evaluate the dental health status and toothbrushing behavior among Sana'a University students, and to explore any associations with different factors. In this cross-sectional study, the dental health of 360 students from the dental, medical, and literature faculties (120 each) at Sana'a University were examined using the Decayed, Missing, and Filled Teeth (DMFT) index. Data regarding study field, grade, toothbrushing behavior, parents' education, and smoking and khat chewing habits were recorded. Nearly 76% of students (n = 273) reported regularly brushing their teeth. Excluding fathers' education levels and khat chewing, other factors (faculty, grade, sex, mothers' education, and smoking) were significant independent predictors for this behavior. The overall mean DMFT score (± standard deviation) was 4.13 ± 3.1, and was found to be adversely influenced by smoking, which explained only 1.1% of the variance. Toothbrushing, sex, and smoking were significant independent predictors for the decay score, and explained 10.6% of its variance. Khat chewing was found to be adversely associated with the missing score, with an influence of only 2.9%. The filling score was found to be positively associated with toothbrushing and study grade, which together had an influence of 10%. The dental health and toothbrushing behaviors of Sana'a University students are unsatisfactory, and influenced unequally by different factors. © 2013 Wiley Publishing Asia Pty Ltd.

The aim of the study was to provide a paleopathologic and radiologic overview of the jaws and teeth of 3 Egyptian mummies preserved in the Civic Museum of History and Art in Trieste. Computerized tomography (CT) imaging and postprocessing techniques were used to examine the oral structures. A 16-slice CT scanner was used (Aquilion 16; Toshiba Medical Systems Europe, Zoetermeer, The Netherlands). Scans were obtained at high resolution. Orthogonal-plane and 3-dimensional (3D) reconstructions were created along with curved reconstructions of the lower and upper jaws. Determination of decayed/missing teeth (DMT) and decayed/missing/tooth surfaces (DMTs) were made with 3D images. Analyses revealed differences in the embalming techniques and state of preservation of the bodies. Marked wear of the occlusal surfaces was a characteristic finding in all of the mummies. The DMT and DMTs were low compared with values for contemporary populations. Two mummies had fully erupted third molars. All mummies exhibited bone changes consistent with periodontitis. The CT evaluations of the oral structures of the mummies provided insight into the dental status and oral diseases of these ancient Egyptians. The low DMT and DMTs values and indications of periodontitis may be associated with the lifestyle of these Egyptians. The fully erupted and well aligned third molars may represent a morphologic adaptation of the arches to the muscular activity associated with grinding tough foods.

This study aimed to evaluate the impact of dental caries treatment on oral health-related quality of life (OHRQoL) among schoolchildren and the responsiveness of the Child Perceptions Questionnaire (CPQ8-10 ) instrument. Brazilian schoolchildren, 8-10 yr of age, were randomly selected and assigned to two groups--dental caries treatment (DCT) and caries-free (CF)--according to their caries experience [decayed, missing, or filled primary teeth (dmft) and decayed, missing or filled secondary teeth (DMFT) values of ≥ 0]. The CPQ8-10 instrument was administered at baseline and at 4 wk of follow-up (i.e. 4 wk after completion of dental treatment). In the DCT group, increases in CPQ8-10 scores were observed between the baseline and follow-up results. However, longitudinal evaluation of the CF group demonstrated no statistically significant difference in CPQ8-10 scores. Responsiveness of the CPQ8-10 instrument (magnitude of change in CPQ8-10 scores) in the DCT group was greater (effect size >0.7) than in the CF group. The findings of this study show that dental caries treatment has an important impact on OHRQoL of children. The CPQ8-10 was considered an acceptable instrument for longitudinal measurement of changes in OHRQoL. © 2015 Eur J Oral Sci.

Since 1995 the Department of Community Dentistry of the University of Pretoria has been involved in the rendering of mobile primary oral health care services to children in the Hammanskraal area of Gauteng, South Africa, as part of their students' community-based training. Mokonyama Primary School was identified as the first school where a primary oral health care service could be rendered. The objective of this study was to evaluate the impact (outcomes) of a fissure sealant program on the dentition status of the school children. Seven years after the implementation of the program, the dentition status of children at Mokonyama was compared with that of a comparable group of children from the same area who were not exposed to the program. The results showed that the decayed, missing, and filled teeth in the primary dentition (dmft) in the six-year-old group in Mokonyama (1.74) did not differ significantly from the dmft (1.43) of the control group (p = 0.49). The decayed, missing, and filled teeth in the permanent dentition (DMFT) of 0.59 for the fifteen-year-old group in Mokonyama, however, differed significantly (p = 0.0001) from the DMFT of the control group (2.38). Fifteen-year-old children in Mokonyama had 75.2 percent fewer caries than their counterparts in the control group.

Endodontic treatment, involves removal of the dental pulp and its replacement by a root canal filling. Restoration of root filled teeth can be challenging due to structural differences between vital and non-vital root filled teeth. Direct restoration involves placement of a restorative material e.g. amalgam or composite directly into the tooth. Indirect restorations consist of cast metal or ceramic (porcelain) crowns. The choice of restoration depends on the amount of remaining tooth which may influence long term survival and cost. The comparative in service clinical performance of crowns or conventional fillings used to restore root filled teeth is unclear. To assess the effects of restoration of endodontically treated teeth (with or without post and core) by crowns versus conventional filling materials. We searched the following databases: the Cochrane Oral Health Group's Trials Register, CENTRAL, MEDLINE via OVID, EMBASE via OVID, CINAHL via EBSCO, LILACS via BIREME and the reference lists of articles as well as ongoing trials registries.There were no restrictions regarding language or date of publication. Date of last search was 13 February 2012. Randomised controlled trials (RCTs) or quasi-randomised controlled trials in participants with permanent teeth which have undergone endodontic treatment. Single full coverage crowns compared with any type of filling materials for direct restoration, as well as indirect partial restorations (e.g. inlays and onlays). Comparisons considered the type of post and core used (cast or prefabricated post), if any. Two review authors independently assessed trial quality and extracted data. One trial judged to be at high risk of bias due to missing outcome data, was included. 117 participants with a root filled premolar tooth restored with a carbon fibre post, were randomised to either a full coverage metal-ceramic crown or direct adhesive composite restoration. At 3 years there was no reported difference between the non-catastrophic failure rates in both groups. Decementation of the post and marginal gap formation occurred in a small number of teeth. There is insufficient evidence to support or refute the effectiveness of conventional fillings over crowns for the restoration of root filled teeth. Until more evidence becomes available clinicians should continue to base decisions on how to restore root filled teeth on their own clinical experience, whilst taking into consideration the individual circumstances and preferences of their patients.

In October 2009, the grave of an unknown World War I (WWI) U.S. service member was exhumed in Rembercourt-Sur-Mad Village, in the Lorraine Region of France. The skeletal remains and material evidence were accessioned into the Joint POW/MIA Accounting Command's (JPAC) Central Identification Laboratory (CIL). The personnel records for the associated casualty were requested, received, and reviewed. A dental profile was present among the service member's personal information. There were multiple points of concordance between the dental records of the associated casualty, and the recovered dental remains to include eight restored teeth, 15 unrestored teeth, and three antemortem missing teeth. Distinctive restorations which compared favorably included a porcelain crown and multiple gold foil fillings. All lines of evidence (historical, material evidence/personal effects, anthropological, and dental) and the circumstances of loss compared positively with the associated casualty. On April 1, 2010, the previously unaccounted-for U.S. service member was positively identified and on June 23, 2010, was buried with full military honors at Arlington National Cemetery.

Asymmetric extractions in a patient with a hopeless maxillary central incisor, followed by treatment with mini-implant anchorage.

PubMed

Jung, Min-Ho

2018-05-01

Premolar extraction is 1 option for treatment of patients with malocclusion and severe crowding or protrusion. When the patient has missing or hopeless teeth other than premolars, it is possible to consider removal of those teeth to use the space to decrease crowding. A 15-year-old girl sought treatment for severe crowding. She had already lost her maxillary right first premolar as a result of caries 1 year previously and had a hopeless maxillary right central incisor. Her mandibular left first molar still caused discomfort even after endodontic treatment. Extractions of the maxillary right central incisor and mandibular right first premolar and left first molar were chosen to resolve the occlusion problems. Orthodontic mini-implants were placed to translocate the maxillary left central incisor across the midpalatal suture to use the space in the maxillary right quadrant to relieve the crowding. Although a different extraction option was used in each quadrant, the final occlusion was acceptable. After debonding, porcelain crowns were placed on the anterior teeth to improve esthetics. The treatment result remained stable after 2 years of retention. Copyright © 2018 American Association of Orthodontists. Published by Elsevier Inc. All rights reserved.

Diabetes is a global health problem and its prevalence is increasing worldwide. The objective of the study was to investigate the effect of diabetes on the periodontal status of a Pakistani population with poor oral hygiene. Eighty-eight individuals with diabetes and 80 non-diabetic individuals were recruited from a disadvantaged district in Karachi, Pakistan. The group with diabetes comprised 50 males and 38 females, and the non-diabetic group 43 males and 37 females. All underwent clinical and radiographic examination. The average numbers of teeth in the diabetes and non-diabetes groups were 24 and 26, respectively. The odds ratio (OR) for missing or fewer teeth was 2.3 times higher for diabetics than for non-diabetics (CI 1.32-4.14; p<0.001). Diabetic patients had more sites with plaque than did non-diabetics (OR 1.96, CI 0.99-3.88; p<0.056). Moderate to severe periodontitis was significantly more prevalent among diabetic patients (p<0.01). In this disadvantaged population with poor oral hygiene, diabetes has had a strongly negative influence on oral health: diabetic patients have fewer teeth, more plaque, and a higher prevalence of moderate to severe periodontal disease than non-diabetics.

Oral Health, Nutritional Choices, and Dental Fear and Anxiety

Oral health is an integral part of overall health. Poor oral health can lead to an increased risk of chronic diseases including diabetes mellitus, cardiovascular disease, and some types of cancer. The etiology of these diseases could be linked to the individual’s inability to eat a healthy diet when their dentition is compromised. While periodontal or implant surgery may be necessary to reconstruct tissue around natural teeth or replace missing teeth, respectively, some individuals avoid such interventions because of their associated fear and anxiety. Thus, while the relationship between poor oral health, compromised nutritional choices and fear and anxiety regarding periodontal procedures is not entirely new, this review provides an up-to-date summary of literature addressing aspects of this complex relationship. This review also identifies potential strategies for clinicians to help their patients overcome their fear and anxiety associated with dental treatment, and allow them to seek the care they need.

Reduced number of teeth with underdeveloped alveolar ridges poses a greatest prosthetic challenge in rehabilitation of ectodermal dysplasia patients (ED). Furthermore, surgical risks and financial constraints may preclude the implant supported prosthesis, the most desirable treatment option in an adult ED patient. Long edentulous span does not permit fixed dental prosthesis (FDP) as well. Telescopic denture by incorporating the best of both fixed and removable prosthesis can be a viable treatment alternative for ED patients with compromised dentition and limited finances. A 21-year-old young girl presented with chief complaint of esthetics and mastication due to missing upper and lower teeth. A provisional diagnosis of ED was made based on familial history, physical, and oral examination. This clinical report describes management of an adult ED patient by means of telescopic overdenture prosthesis in mandibular arch and FDP in maxillary arch which restored esthetics, function, and social confidence of the patient in a cost effective manner.

Introduction: Aim of this systematic review was to assess the orthodontic related issues which currently provide the best evidence as documented by meta-analyses, by critically evaluating and discussing the methodology used in these studies. Material and Methods: Several electronic databases were searched and handsearching was also performed in order to identify the corresponding meta-analyses investigating orthodontic related subjects. In total, 197 studies were retrieved initially. After applying specific inclusion and exclusion criteria, 27 articles were identified as meta-analyses treating orthodontic-related subjects. Results: Many of these 27 papers presented sufficient quality and followed appropriate meta-analytic approaches to quantitatively synthesize data and presented adequately supported evidence. However, the methodology used in some of them presented weaknesses, limitations or deficiencies. Consequently, the topics in orthodontics which currently provide the best evidence, include some issues related to Class II or Class III treatment, treatment of transverse problems, external apical root resorption, dental anomalies, such as congenital missing teeth and tooth transposition, frequency of severe occlusal problems, nickel hypersensitivity, obstructive sleep apnea syndrome, and computer-assisted learning in orthodontic education. Conclusions: Only a few orthodontic related issues have been so far investigated by means of MAs. In addition, for some of these issues investigated in the corresponding MAs no definite conclusions could be drawn, due to significant methodological deficiencies of these studies. According to this investigation, it can be concluded that at the begin of the 21st century there is evidence for only a few orthodontic related issues as documented by meta-analyses, and more well-conducted high quality research studies are needed to produce strong evidence in order to support evidence-based clinical practice in orthodontics.

The aim of this study was to evaluate oral function rehabilitation in patients with hypohidrotic ectodermal dysplasia (HED) using implant-supported prostheses based on bone augmentation. From September 2005 and March 2009, 25 HED patients were chosen for clinical data analysis in this study. The criteria for patient selection included the following: the display of clinical features of HED, the number of congenitally missing teeth (>5), the patient age (>16 years), the patient's willingness, and the patient's tolerance for bone graft surgery and implant placement. Follow-up evaluations were initiated from the time of implant prosthetic placement and scheduled annually for 3-5 years. The effects of oral function reconstruction were assessed based on the cumulative survival and success rates of implants, the health of the peri-implant area, and the degree of patient satisfaction. Twenty-five HED patients received 169 conventional implants and 10 zygomatic implants (179 total implants). During 3-5 years of post-loading evaluations, 5 of the 179 implants failed and 3 implants were removed. The 3-year success and cumulative survival rates were 97.2% and 98.3%, respectively. Furthermore, periodontal probing and radiographic assessments showed that the 3-year incidence of peri-implantitis was 4.5%. Finally, HED patients expressed high degrees of satisfaction with their facial contours, masticatory function, pronunciation ability, and comfort with the implant-supported prostheses. The results of this 3- to 5-year retrospective study indicate that the oral function of HED patients can be effectively reconstructed using bone augmentation and implant-supported prostheses; however, longer term results are warranted in the future.

For the first time, chimpanzees have been observed using tools to clean the corpse of a deceased group member. A female chimpanzee sat down at the dead body of a young male, selected a firm stem of grass, and started to intently remove debris from his teeth. This report contributes novel behaviour to the chimpanzee’s ethogram, and highlights how crucial information for reconstructing the evolutionary origins of human mortuary practices may be missed by refraining from developing adequate observation techniques to capture non-human animals’ death responses.

This paper will give an overview of the aetiology of ED and describe the manifestations and dental management of this condition. In particular, the important role of the dental practitioner in the identification and management of patients with ED will be highlighted. CPD/Clinical Relevance: Dental practitioners should be aware of the oral features of ectodermal dysplasia and be able to make timely referrals and provide appropriate continuing care for these patients.

Factors which influence levels of selected organisms in saliva of older individuals.

The most commonly measured bacterial parameters in saliva are the levels of the mutans group streptococci and lactobacilli, which have diagnostic implications for the incidence of dental decay. Diagnostic guidelines which are applicable to children and young adults in whom most, if not all, teeth are present and in whom the rate of stimulated saliva is almost always greater than 0.5 ml/min have been developed. Dental decay is a potential health problem of considerable magnitude among elderly individuals. In elderly individuals, missing teeth, the presence of dentures, and a reduced salivary flow could confound the interpretation of salivary levels of cariogenic bacteria. In the present study, in which saliva was collected from more than 560 elderly individuals (average age, 70 +/- 8 years), there was a significant positive relationship between the salivary levels of Streptococcus mutans and increased numbers of teeth. There was a positive association between the salivary levels of S. mutans and decay when the data were stratified for the presence of a complaint of xerostomia and the presence of dentures. However, a similar analysis indicated that lactobacilli and yeasts were more likely to be associated with decay. The various variables which could influence the bacterial counts per milliliter of saliva, e.g., independent or dependent living status, complaint of xerostomia, stimulated salivary flow, salivary pH, the presence of dentures, number of teeth, and decay, were analyzed simultaneously by using a multivariable linear model. In that analysis the number of decayed teeth was significantly associated with the presence of lactobacilli (P = 0.0001) and yeasts (P = 0.025) but not with the presence of S. mutans.(ABSTRACT TRUNCATED AT 250 WORDS) PMID:8567881

The study was aimed to acquire better understanding of C-shaped canal systems in mandibular second molar teeth through a clinical approach using sophisticated techniques such as surgical operating microscope and cone beam computed tomography (CBCT). A total of 42 extracted mandibular second molar teeth with fused roots and longitudinal grooves were collected randomly from native Indian population. Pulp chamber floors of all specimens were examined under surgical operating microscope and classified into four types (Min's method). Subsequently, samples were subjected to CBCT scan after insertion of K-files size #10 or 15 into each canal orifice and evaluated using the cross-sectional and 3-dimensional images in consultation with dental radiologist so as to obtain more accurate results. Minimum distance between the external root surface on the groove and initial file placed in the canal was also measured at different levels and statistically analyzed. Out of 42 teeth, maximum number of samples (15) belonged to Type-II category. A total of 100 files were inserted in 86 orifices of various types of specimens. Evaluation of the CBCT scan images of the teeth revealed that a total of 21 canals were missing completely or partially at different levels. The mean values for the minimum thickness were highest at coronal followed by middle and apical third levels in all the categories. Lowest values were obtained for teeth with Type-III category at all three levels. The present study revealed anatomical variations of C-shaped canal system in mandibular second molars. The prognosis of such complex canal anatomies can be improved by simultaneous employment of modern techniques such as surgical operating microscope and CBCT.

In recent years, dental implants made from zirconia have been further developed and are considered a reliable treatment method for replacing missing teeth. The aim of this study was to analyze dental implants made from zirconia regarding their clinical performance compared with natural teeth (control). One hundred six zirconia implants in 38 adults were analyzed in a clinical study after 1 year of loading. The plaque index (PI), bleeding on probing (BOP), probing pocket depth (PPD), probing attachment level (PAL), and creeping or recession (CR/REC) of the gingiva were detected and compared with natural control teeth (CT). Furthermore, the papilla index (PAP), Periotest values (PTV), microbial colonization of the implant/dental sulcus fluid, and patient satisfaction were assessed. The survival rate was 100%. No statistical significance was observed between implants and teeth regarding BOP, PPD, and PAL. A statistical significance was detected regarding PI and CR/REC with significantly less plaque accumulation and recession in the study group. Mean PAP was 1.76 ± 0.55, whereas the mean PTV was -1.31 ± 2.24 (range from -5 to +6). A non-statistically significant higher colonization of periodontitis/peri-implantitis bacteria was observed in the implant group. The questionnaire showed that the majority of the patients were satisfied with the overall treatment. One-piece zirconia dental implants exhibited similar clinical results (BOP, PPD, and PAL) compared with natural teeth in regard to adhesion of plaque (PI) and creeping attachment (CR/REC); zirconia implants performed even better. The favorable results for PAL and CR/REC reflect the comparable low affinity of zirconia for plaque adhesion. Patient satisfaction indicated a high level of acceptance for zirconia implants. However, a long-term follow-up is needed to support these findings.

Zika virus infection during pregnancy can lead to congenital Zika syndrome. Implementation of screening programs and interpretation of test results can be particularly challenging during ongoing local mosquitoborne transmission. We conducted a retrospective chart review of 2,327 pregnant women screened for Zika virus in Miami–Dade County, Florida, USA, during 2016. Of these, 86 had laboratory evidence of Zika virus infection; we describe 2 infants with probable congenital Zika syndrome. Delays in receipt of laboratory test results (median 42 days) occurred during the first month of local transmission. Odds of screening positive for Zika virus were higher for women without health insurance or who did not speak English. Our findings indicate the increase in screening for Zika virus can overwhelm hospital and public health systems, resulting in delayed receipt of results of screening and confirmatory tests and the potential to miss cases or delay diagnoses.

Ankyloglossia is a congenital oral anomaly characterized by the presence of a hypertrophic and short lingual frenulum. Mutations in the gene encoding the transcription factor TBX22 have been involved in isolated ankyloglossia and X-linked cleft palate. The knockout of Lgr5 in mice results in ankyloglossia. Here, we report a five-generation family including patients with severe ankyloglossia and missing lower central incisors. Two members of this family also exhibited congenital anorectal malformations. In this report, male-to-male transmission was in favor of an autosomal dominant inheritance, which allowed us to exclude the X-linked TBX22 gene. Linkage analysis using short tandem repeat markers located in the vicinity of LGR5 excluded this gene as a potential candidate. These results indicate genetic heterogeneity for ankyloglossia. Further investigations with additional families are required in order to identify novel candidate genes. © 2018 Wiley Periodicals, Inc.

Cyclopia is a rare type of holoprosencephaly and a congenital disorder characterized by the failure of the embryonic forebrain to properly divide the orbits of the eye into two cavities (the embryonic forebrain is normally responsible for inducing the development of the orbits). As a result a birth defect in which there is only one eye is developed. This eye is centrally placed in the area normally occupied by the root of the nose. As a rule, there is a missing nose or a non-functioning nose in the form of a proboscis (a tubular appendage) located above the central eye. In this report the macroscopic, radiographic, and immunohistochemical findings of a case of true cyclopia in a female fetus are described. Cyclopia is a lethal condition that is associated with dramatic symmetric deformities of the nose, skull, orbits, and brain.

Most affected individuals have characteristic facial features that evolve with age; a broad, webbed neck; increased bleeding tendency; and a high incidence of congenital heart disease, failure to thrive, short stature, feeding difficulties, sternal deformity, renal malformation, pubertal delay, cryptorchidism, developmental or behavioral problems, vision problems, hearing loss, and lymphedema. Familial recurrence is consistent with an autosomal dominant mode of inheritance, but most cases are due to de novo mutations. Diagnosis can be made on the basis of clinical features, but may be missed in mildly affected patients. Molecular genetic testing can confirm diagnosis in 70% of cases and has important implications for genetic counseling and management. Most patients with Noonan syndrome are intellectually normal as adults, but some may require multidisciplinary evaluation and regular follow-up care. Age-based Noonan syndrome-specific growth charts and treatment guidelines are available.

To evaluate the relationship between the oral health condition, the nutrient intake and the body mass index (BMI) in elderly people. Impaired dentition has been associated with an inadequate consumption of key nutrients and with changes in nutritional status in elderly people. The sample comprised 887 elderly people, aged 60 and over, of whom 816 underwent a clinical oral examination and were allocated into groups according to the numbers of teeth and number of posterior occluding pairs of natural teeth. Nutritional status was determined using the BMI. Dietary intake was assessed by a 24-h diet recall interview and the data from these records were converted to nutritional intake using DietPro software. Differences between means were evaluated using ANOVA, together with the Tukey test or Dunnet test, according to the normality of the data. Associations between categorical variables were tested using chi-square analysis. Ages ranged from 60 to 96 years (mean, 71.46 years), with 47% of the respondents in the 60-to 69-year-old group. A high DMFT index (mean, 27.81) was observed with the missing component accounting for 88.8% of the index. Significant differences were observed between the mean intake of nutrients and the number of posterior occluding pairs of natural teeth (p < 0.05). No significant differences were found between the number of teeth and BMI. Nutrient intake is associated with the oral health status as defined by clinical measures.

The purpose of this study was to evaluate the number of distal roots and canals in mandibular first molars and their internal anatomy radiographically within Iranian population. A total of 310 distal roots of mandibular first molars were incorporated in this study and evaluated in terms of number of roots and number and types of canals. Root canal systems were studied in vitro by means of radiography and based on Vertucci's classifications. It was shown that 4.5% of the teeth in this study had two distal roots, of which, 100% indicated type I for both distobuccal and distolingual roots. Among all the teeth, 43.2% had two canals, 24.2% two apical foramina, and 38.7% two orifices in their distal roots. According to Vertucci's classification 54.9% of the teeth were type I, 19% type II, 1.9% type III, 14.2% type IV, 4.2% type V, 1% type VI, 0.3% type VII and 0% type VIII. In as many as 43.2% of all teeth assessed in this study, bicanaled distal roots were observed, dentists are always recommended to search for the second canal in distal roots of mandibular first molars. In case the second canal in the distal root is missed, failure of endodontic treatment will be anticipated. A rectangular type access cavity design allows better visualization and negotiation of the probable second canals within the distal roots of mandibular first molars.

The 2020 Sustainable Development goals call for 100% certified interruption or control of the three main forms of Chagas disease transmission in Latin America. However, how much will achieving these goals to varying degrees control Chagas disease; what is the potential impact of missing these goals and if they are achieved, what may be left? We developed a compartmental simulation model that represents the triatomine, human host, and non-human host populations and vector-borne, congenital, and transfusional T. cruzi transmission between them in the domestic and peridomestic settings to evaluate the impact of limiting transmission in a 2,000 person virtual village in Yucatan, Mexico. Interruption of domestic vectorial transmission had the largest impact on T. cruzi transmission and prevalence in all populations. Most of the gains were achieved within the first few years. Controlling vectorial transmission resulted in a 46.1-83.0% relative reduction in the number of new acute Chagas cases for a 50-100% interruption in domestic vector-host contact. Only controlling congenital transmission led to a 2.4-8.1% (30-100% interruption) relative reduction in the total number of new acute cases and reducing only transfusional transmission led to a 0.1-0.3% (30-100% reduction). Stopping all three forms of transmission resulted in 0.5 total transmission events over five years (compared to 5.0 with no interruption); interrupting all forms by 30% resulted in 3.4 events over five years per 2,000 persons. While reducing domestic vectorial, congenital, and transfusional transmission can successfully reduce transmission to humans (up to 82% in one year), achieving the 2020 goals would still result in 0.5 new acute cases per 2,000 over five years. Even if the goals are missed, major gains can be achieved within the first few years. Interrupting transmission should be combined with other efforts such as a vaccine or improved access to care, especially for the population of already infected individuals.

Peripheral arterial disease (PAD) is an important cardiovascular disorder of the peripheral arteries. Chronic infections, such as periodontitis, may play an important role in the etiology and pathophysiology of PAD and other cardiovascular conditions. Recently, Streptococcus mutans has been found with high frequency in atheromatous plaques. The aim of this study is to evaluate the possible clinical and microbiologic association between PAD and periodontitis and dental caries. Thirty patients with PAD and 30 control individuals were selected. PAD and its severity were established by the use of the ankle-brachial index (ABI). Clinical attachment loss (AL); probing depth; decayed, missing, and filled teeth (DMFT) index; and C-reactive protein (CRP) levels were evaluated. The presence of bacterial DNA from Streptococcus mutans, Porphyromonas gingivalis, Tannerella forsythia, Prevotella intermedia, Treponema denticola, and Aggregatibacter actinomycetemcomitans was identified by polymerase chain reaction in subgingival biofilm and serum. Patients with ≥30% AL ≥ 4 mm had six-fold increased risk of having PAD (odds ratio = 8.18; 95% confidence interval = 1.21 to 35.23; P = 0.031). There was statistical difference in the CRP (P = 0.0413) and DMFT index (P = 0.0002), with elevated number of missing teeth (P = 0.0459) in the PAD group compared with the control group. There were no significant differences in the frequency of bacteria in serum and subgingival plaque. There was a positive relationship between periodontitis based on AL and PAD determined by the ABI (odds ratio = 8.18).

To identify standards, how entities of dental status are assessed and reported from full-arch radiographs of adults. A PubMed (Medline) search was performed in November 2011. Literature had to report at least one out of four defined entities using radiographs: number of teeth or implants; caries, fillings or restorations; root-canal fillings and apical health; alveolar bone level. Cohorts included to the study had to be of adult age. Methods of radiographic assessment were noted and checked for the later mode of report in text, tables or diagrams. For comparability, the encountered mode of report was operationalized to a logical expression. Thirty-seven out of 199 articles were evaluated via full-text review. Only one article reported all four entities. Eight articles reported at the maximum 3 comparable entities. However, comparability is impeded because of the usage of absolute or relative frequency, mean or median values as well as grouping. Furthermore the methods of assessment were different or not described sufficiently. Consequently, established sum scores turned out to be highly questionable, too. The amount of missing data within all studies remained unclear. It is even so remissed to mention supernumerary and aplased teeth as well as the count of third molars. Data about dental findings from radiographs is, if at all possible, only comparable with serious limitations. A standardization of both, assessing and reporting entities of dental status from radiographs is missing and has to be established within a report guideline.

To evaluate and compare the oral health status and the impact of supervised toothbrushing and oral health education among school children of urban and rural areas of Maharashtra, India. A total of 200 school children in the age group 12-15 years were selected by stratified random sampling technique from two schools and were further divided into two groups: Group A (urban school) and Group B (rural school). Both the groups were again subdivided into control group and study group. Supervised toothbrushing was recommended for both the groups. The toothbrushing teaching program included session on oral health education, individual toothbrushing instructions, and supervised toothbrushing. Dental caries increment, plaque scores, and gingival status were assessed as per the World Health Organization (WHO) criteria (1997), Turesky-Gilmore-Glickman modification of the Quigley Hein Plaque Index, and Loe-Silness Gingival Index (1963), respectively. Cronbach's alpha, Chi-square test, paired t-test, and unpaired t-test were utilized for data analysis. The mean plaque and gingival score reduction was significantly higher in the study groups as compared to the control groups. An increase in the mean of Decayed, missing, filled teeth (DMFT) and Decayed, missing, filled teeth and surfaces (DMFS) scores throughout the study period was seen in children who participated in study. Oral health education was effective in establishing good oral health habits among school children and also in enhancing the knowledge of their parents about good oral health.

Poor dental health has been associated with increased risks of oral, esophageal, and gastric cancer and may also be associated with pancreatic cancer. In addition, Helicobacter pylori has been found in dental plaque and has been associated with periodontal disease and pancreatic cancer. The objective was to investigate prospectively the relation between dentition history and pancreatic cancer in the Alpha-Tocopherol, Beta-Carotene Cancer Prevention Study cohort in Finland and the association between dentition history and H. pylori seropositivity in a cross-sectional sample of subjects without cancer (n = 475) from the same cohort. Of the 29,104 male smokers aged 50-69 y in the cohort for whom there were complete data, 174 developed pancreatic cancer from 1985 to 1997. Cox proportional hazard models were used to estimate age-, smoking-, education-, urban living-, and height-adjusted hazard ratios and 95% CIs for pancreatic cancer, and logistic regression models were used to estimate age- and education-adjusted odds ratios for H. pylori carriage. Tooth loss was positively associated with pancreatic cancer (edentulous compared with missing 0-10 teeth: hazard ratio = 1.63; 95% CI: 1.09, 2.46; P for trend = 0.02) but was not significantly associated with H. pylori seropositivity (edentulous compared with missing 0-10 teeth: odds ratio = 1.30; 95% CI: 0.73, 2.32; P for trend = 0.37). Additional studies are needed to evaluate the association between tooth loss and pancreatic cancer, as well as cancers at other gastrointestinal sites, particularly with respect to possible biological mechanisms.

Background Early diagnosis of xerostomia is very important for oral health. The purpose of this study was to determine the unstimulated whole salivary flow rates (UWSFR) in a Jordanian Arab population aged 15 years and older. The effect of age, gender, height, weight, body mass index (BMI), smoking, alcohol consumption, and dental conditions, on UWSFR was also investigated. Methods The study was conducted on 244 subjects, 110 males and 134 females, with an average age of 33 ± 15.5 years. They were healthy, unmedicated, and with no history of dry mouth. Unstimulated whole saliva was collected during five minutes, and UWSFRs (ml/min) were determined. Data were analyzed by univariate analysis and multivariate regression analysis. Results The mean UWSFR was 0.46 ± 0.25 ml/min (range: 0.10-1.6 ml/min). Eighteen patients (7.4%) had UWSFR between < 0.20 ml/min. In univariate analysis, UWSFR was significantly affected by age, BMI, number of missing and restored teeth, and DMFT score. Regression analysis revealed that only age and number of missing teeth were of significance in explaining the variability of the UWSFR. Conclusions We established basic standard values of UWSFR to be used in the evaluation of Jordanian patients with complaints of xerostomia and to be compared to data reported in other studies. UWSFR 0.1 ml/min could be considered the cut-off value that distinguishes normal from abnormal salivary function in this healthy unmedicated population.

To assess differences in the oral diseases/conditions between adults and older adults. A cross-sectional study was carried out with all adults and older adults in Luzerna, South Brazil (n = 569). Clinical data included use of and need for dental prostheses; number of decayed, missing and filled teeth; and temporomandibular disorder. Differences between adults and older adults were evaluated using χ(2) -tests. Associations between independent variables and the use of and need for dental prostheses were determined using Poisson regression analyses (P < 0.05). Increased number of decayed, missing and filled teeth, use of and need for dental prostheses, higher use of complete dentures, and fewer temporomandibular disorder signs and symptoms were observed in older adults. After adjustments, lower social class (P = 0.001) and unmarried status (P = 0.05) were associated with greater need for prosthetic rehabilitation. Women (P = 0.02), older individuals (P < 0.001) and those of lower socioeconomic status (P = 0.001) had a higher risk of using prostheses. A significant difference of oral conditions between adults and older adults was observed. The frequency of use of and need for dental prostheses was higher for older adults, although they had reported lower frequency of temporomandibular disorder. Women, married and individuals of higher socioeconomic status showed better oral health conditions. Geriatr Gerontol Int 2016; 16: 1014-1020. © 2015 Japan Geriatrics Society.

In Finland, 3 patients have been diagnosed with Nager syndrome (NS) during the last 17 years. Thus the incidence for NS in Finland is 3:1,000,000. The craniofacial structures and dental development of these patients were studied clinically and radiographically at the age of 3-4 years, and compared to age-matched controls and to the norms of the Finnish population. The striking structural finding was a severely short, retrognathic and posteriorly rotated mandible. Especially the ramus was deficient; its height was, on average, less than one-third of that of the control group. All children were tracheostomized neonatally. At the age of 3-4, the lower pharyngeal airway was still severely obstructed or completely closed. Nasopharyngeal airway was wide and the soft palate was missing in all patients. All patients had a complete deciduous dentition, but agenesis of permanent teeth (ranging from 2-10 missing teeth) was observed in each patient. Accelerated dental development was found in two subjects. Condylar ankylosis or severely limited mouth opening were observed. The present findings give new information and quantify earlier observations of craniofacial structures and dental development in NS. Analysis of facial structures suggests that if surgical intervention is needed to enable better breathing, the goal of the structural correction should be aimed at the most deficient structure, namely the ramus height. As a result of severe dentofacial deviation, a treatment process through the growth requires multidisciplinary teamwork of surgeons, pediatrists, orthodontists and prosthodontists.

The purpose of this study was to determine the occlusal status in young Asian male adults of three ethnic groups. Study models of a sample of male army recruits (N = 339, age 17-22 years) with no history of orthodontic treatment were assessed. The ethnic proportions of the sample were Chinese 76.1% (n = 258), Malay 17.7% (n = 60), and Indian 6.2% (n = 21). British Standard Institute (BSI) and Angle's classification were used to determine incisor and molar relationships, respectively. Chi-square test or Fisher's Exact test was performed to compare the occlusal traits between ethnic groups. The distribution of incisor relationships of the total sample consisted of Class I = 48.1%, Class II/1 = 26.3%, Class II/2 = 3.2%, and Class III = 22.4%. Right Angle's molar relationships were 49.9%, 24.5%, and 24.2% whereas left Angle's molar relationships were 53.1%, 25.1%, and 21.2% for Class I, II, and III, respectively. Comparison between ethnic groups found that Indian subjects were more likely to have Class II/1 malocclusions and clinically missing permanent teeth (P < .05). The study found that the overall prevalence of malocclusion (BSI) was Class I, Class II/1, Class III, and Class II/2 in descending order of proportions. Angle's Class I molar was most prevalent followed by Class II and Class III relations. A significant difference in occlusal status between the ethnic groups was found regarding incisor relationship and missing permanent teeth (P < .05).

Maturation of the grafted volume after lateral sinus elevation is crucial for the long-term survival of dental implants. To compare endo-sinus histomorphometric bone formation between the solo- and two-window maxillary sinus augmentation techniques with or without membrane coverage for the rehabilitation of multiple missing posterior teeth. Patients with severely atrophic posterior maxillae were randomized to receive lateral sinus floor elevation via the solo-window technique with membrane coverage (Control Group) or the two-window technique without coverage (Test Group). Six months after surgery, bone core specimens harvested from the lateral aspect were histomorphometrically analyzed. Ten patients in each group underwent 21 maxillary sinus augmentations. Histomorphometric analysis revealed mean newly formed bone values of 26.08 ± 16.23% and 27.14 ± 18.11%, mean connective tissue values of 59.34 ± 12.42% and 50.03 ± 17.13%, and mean residual graft material values of 14.6 ± 14.56% and 22.78 ± 10.83% in the Test and Control Groups, respectively, with no significant differences. The two-window technique obtained comparative maturation of the grafted volume even without membrane coverage, and is a viable alternative for the rehabilitation of severely atrophic posterior maxillae with multiple missing posterior teeth. © 2017 Wiley Periodicals, Inc.

[Dental alveolar bone and dental arch remodeling in children: orthodontic diagnosis and treatments based on individual child arch development].

PubMed

Xiaobing, Li

2016-12-01

The etiology of malocclusions basically involves both congenital and environmental factors. Malocclusion is the result of the abnormal development of the orofacial complex (including tooth, dental alveolar bone, upper and lower jaws). Early orthodontic interceptive treatments involve the elimination of all congenital and environmental factors that contribute to the malformation of the orofacial complex, as well as interrupt the deviated development of the orofacial complex and the occlusion. Early orthodontic interceptive treatments mainly aim to use children's growth potential to correct abnormal developments of occlusions and orthodontically treat malocclusions more efficiently. The early orthodontic interceptive treatments include correcting the child's bad oral habits, training the abnormal functioned para-oral muscles, maintaining the normal eruptions of succeeding permanent teeth, applying interceptive treatments to the mal-developed teeth, and employing functional orthopedic treatments for abnormal growths of the upper and lower jaws. In orthodontics, correcting mal-positioned teeth is called orthodontic treatment, while rectifying the abnormal relationships of the upper and lower jaws is called functional orthopedic treatment. However, no clear definition is available as regards to the early orthodontic interceptive treatment of malocclusions caused by the deviated development of the dental alveolar bone. This new theory of "early dental alveolar bone and dental arch remodeling technique" was proposed by Professor Li Xiaobing of the Department of Pediatric Dentistry, Faculty of Pediatric Dentistry and Orthodontics in West China Hospital of Stomatology through his clinical analyses and investigation of his early orthodontic interceptive treatments. He defined the early orthodontic corrections of abnormal growth of dental alveolar bone as "remodel". The "early dental alveolar bone and dental arch remodeling theory and technique" is proved useful in malocclusion diagnosis and treatment planning during early orthodontic interceptive treatment with malformed dental arch. With the development of the theory and technique, the author intended to prevent and intercept the malocclusion development more effectively and efficiently. This review presents the development and clinical usages of the theory which to provide a new vision in the analysis of malocclusions on the basis of the developmental mechanism of the alveolar bone and dental arch. With clinical case illustration, the author demonstrateshis successful orthodontic clinical practices with this theory, which may contribute to the development of contemporary orthodontic theories and techniques.

The study was undertaken at Kesariyaji, located in Udaipur district of Rajasthan. There are about 3 million workers who marble mine at Rajasthan. Living conditions of these workers are substandard and most of them are immigrant workers living in tiny shacks. Majority of them belong to lower socioeconomic status with poor educational background. The present study was carried out to estimate dental caries prevalence and treatment needs of laborers working in the green marble mines of Udaipur district. The data was collected using the methods and standards recommended by the WHO. Dentition status and treatment needs along with decayed, missing, and filled teeth (DMFT) index, and decayed, missing, and filled surfaces score were recorded. Standard error of mean was calculated for all the mean values of treatment needs. There were three examiners, who were trained before the survey for inter-examiner variability, and the reliability was tested by means of weighted kappa statistics, which was 90%. The study population comprised 513 men in four age groups of 18-25, 26-34, 35-44, and 45-54 years, respectively. The mean DMFT for all age groups was 3.13 with highest mean of 4.0 for the age group of 45-54 years. Mean decayed teeth were 2.60, 3.33, 1.46, and 1.5 for the age groups 15-24, 25-34, 35-44, and 45-54 years, respectively. Filled component was nil for all age groups. Most of the subjects required one surface filling with a very less proportion needing pulp care. The missing component constituted the major part of DMFT index in the 45-54 years age group and the absence of filled component in the whole study population implies that the treatment needs of the study population are unmet. Thus, intervention in the form of oral health promotion and curative services are the need of the hour.

Gross and important inequities have historically existed in the oral health profiles of New Zealand children. Following the New Zealand Government's strategic oral health vision, launched in 2006, nationally collected information from 2004 to 2013 was used to analyze patterns in the prevalence of no obvious decay experience (caries-free) and mean decayed-missing-filled teeth indices over time and by community water fluoridation (CWF) and ethnic classifications in New Zealand children aged 5 years and in school year 8 (generally aged 12-13 years). National aggregated data collected from children's routine child oral health service dental examinations were retrieved, and combined with demographic information from Statistics New Zealand. Children's CWF status was defined by the public water supply status of their school. Crude and standardized population estimates of caries-free prevalence and mean decayed-missing-filled teeth indices over time were derived. Unweighted linear regression models of main effects and two-factor interactions were investigated by age group. Dental examination data were available from 417,318 children aged 5 years and 471,333 year 8 children; of whom 93,715 (22.5 %) and 94,001 (19.9 %), respectively, were Māori. Dental examination coverage of Māori children was significantly less than their non-Māori counterparts (approximately 11 % and 14 % for aged 5 and year 8 children, respectively). Regression analysis revealed that caries-free prevalence and mean decayed-missing-filled teeth indices significantly improved over the study period for both age groups. Significant and sustained differences were observed between Māori and non-Māori children, and between CWF and non-CWF exposed groups. However, a convergence of dental profiles between non-Māori children in CWF and non-CWF regions was observed. Significant and important gains in New Zealand children's oral health profiles appear to have been made over the last decade. Māori children continued to carry a disproportionate oral health burden, even for those in CWF regions. The apparent profile convergence between non-Māori children in CWF and non-CWF regions is noteworthy; although a likely consequence of demographic shifts and unmeasured confounders. CWF itself did not remove disparities in caries levels between Māori and non-Māori children. Multiple, multi-pronged strategies are needed that overcome the array of factors which disadvantage Māori.

Aim . To assess the prevalence of dental caries, oral hygiene knowledge, status, and practices among visually impaired individuals in Chennai, Tamil Nadu. Materials and Methods . A cross-sectional study was conducted among 404 visually impaired individuals in Chennai city, Tamil Nadu. Four schools were randomly selected for conducting the study. The oral hygiene status, prevalence of caries, and knowledge and attitude towards oral care among visually impaired individuals were collected and analysed. Results . In the present study, whilst 42% of individuals had fair oral hygiene status, 33% had good hygiene followed by 25% having poor oral hygiene. The overall mean number of DMFT was estimated to be 4.5 ± 2.7. The mean number of decayed teeth was 3.1 ± 2.2, mean number of missing teeth was 0.8 ± 1.4, and mean number of filled teeth was 0.5 ± 1.3. Conclusion . Whilst oral hygiene status was found to be relatively fair, there was a high rate of dental caries among the sample population. This shows that there is lack of knowledge regarding oral health maintenance. Therefore, early identification of caries coupled with effective oral health promotion programs providing practical knowledge to visually impaired students would prove beneficial.

We investigated the clinical and radiographic outcomes of autotransplanted teeth over a follow-up period of 2 to 8 years, and summarize the findings of other relevant studies with regard to the primary factors that influence a good prognosis in such patients. Twenty-three patients (6 men, 17 women) who attended Tanggu Stomatological Hospital, Tianjin, China, from 2008 through 2013, were included in the study. These patients presented with a variety of dental problems, including tooth loss, residual crowns, missing first or second molars, dental trauma, tooth fracture, and unrestored teeth. A total of 26 third molars, including 2 immature molars, were autotransplanted in these patients. The success rate of autotransplantation was assessed on the basis of clinical and radiographic outcomes after follow-up periods ranging from 2 to 8 years. Clinical examination revealed stability of all 26 transplanted teeth, with satisfactory masticatory function and no patient discomfort. Radiographic examination revealed normal periapical tissues and an intact lamina dura surrounding the tooth root, indicating adequate healing of periodontal tissues. Autotransplantation achieved good results in the Chinese sample population investigated, and was associated with an excellent prognosis. Rigorous case selection, adequate protection of the periodontal ligament, and proper oral hygiene contribute significantly to the long-term success of the procedure.

Impacted and transposed teeth cause serious difficulties in tooth eruption and movement as well as esthetic and functional outcomes. Proper treatment planning including good biomechanical control is essential in order to avoid side effects during traction and aligning of the impacted and/or transposed teeth. The purpose of the present study was to present a successfully treated female patient having transposed and impacted lower canines by means of a modified lingual arch and fixed orthodontic appliance. A female patient aged 13 years and 9 months presented to the orthodontic department with a chief compliant of bilateral spacing and missing teeth in mandibular dentition. After leveling and creating sufficient space in the mandibular arch for the canines, a modified lingual arch was cemented to the mandibular first molars. The lingual arch had two hooks extending to the distobuccal areas of the canine spaces. Elastic chains were applied between the hooks on the lingual arch and the ligatures tied to the attachments on the canine crowns. The light forces generated by elastic materials caused impacted canines to erupt and tend towards their own spaces in the dental arch. As a result, impacted and transposed lower canines were properly positioned in their spaces, and the treatment results were stable during the retention period. PMID:28540090

In-vitro study was done to evaluate the incidence of MB2 canals using three different methods (CBCT, CLINICAL ANALYSIS AND DENTAL LOUPES) and to compare the efficacy of the three methods in identifying the incidence of MB2 canals in maxillary permanent first molars. The study sample consisted of 120 extracted intact permanent maxillary molars. These extracted teeth were subjected to CBCT. Later the teeth were access opened with naked eye to find the incidence of MB2 canal, and then the teeth were visualised under dental loupe to locate MB2 canal if they were missed under naked eye. Results was statistically analysed by Mc Nemar's tests with Bonferroni correction, Chi square test and Cochran's Q test. CBCT showed high incidence (68.3%) of MB2 canal in maxillary first molars and it showed to be a reliable method in detecting MB2 canal. When compared to dental loupe (52.5%) and naked eye (25%), the dental loupe improved the detection of MB2 canal. Within the parameter of this study in detecting the incidence of MB2 canal, using CBCT dental loupes and naked eye, detection of MB2 canal was significantly higher with CBCT followed by dental loupe and least with naked eye.

Aim. To assess the prevalence of dental caries, oral hygiene knowledge, status, and practices among visually impaired individuals in Chennai, Tamil Nadu. Materials and Methods. A cross-sectional study was conducted among 404 visually impaired individuals in Chennai city, Tamil Nadu. Four schools were randomly selected for conducting the study. The oral hygiene status, prevalence of caries, and knowledge and attitude towards oral care among visually impaired individuals were collected and analysed. Results. In the present study, whilst 42% of individuals had fair oral hygiene status, 33% had good hygiene followed by 25% having poor oral hygiene. The overall mean number of DMFT was estimated to be 4.5 ± 2.7. The mean number of decayed teeth was 3.1 ± 2.2, mean number of missing teeth was 0.8 ± 1.4, and mean number of filled teeth was 0.5 ± 1.3. Conclusion. Whilst oral hygiene status was found to be relatively fair, there was a high rate of dental caries among the sample population. This shows that there is lack of knowledge regarding oral health maintenance. Therefore, early identification of caries coupled with effective oral health promotion programs providing practical knowledge to visually impaired students would prove beneficial. PMID:28458691

Aplasia cutis congenita is a disorder where e newborn child is missing skin from certain areas. It is a rare condition with no particular race or sex more at risk. May occur by itself or be associated with other physical syndromes or disorders. A classification system exists for aplasia cutis congenital consisting of 9 groups, based on the number and location of the skin defects and the presence or absence of other malformations. Causes of aplasia congenital could be heredity, teratogenic substances, placental infarcts, intrauterine infections, ectodermal dysplasias etc. Diagnosis is made based on the clinical findings. Prognosis depends of the other organs malfunction level and lesions size. Our case was an 22 months old Albanian girl, who was recommended to dermatology for a consultation by a pediatric surgeon because of the changes she had on her parietal part of the scalp with missing hair areas. The child has stenosis congenita ani and to her was installed stoma. In order to investigate other accompanied anomalies of the disease, there are made specific consults by neurologist, orthopedist, cardiologist, nephrologists and citogenetics. It was found out a minor visual discoordination, Sy Floppy, Digiti V superductus pedis bill. Laxitas articularum generalisata. It was a great challenge for us to find out that during the first trimester of the pregnancy (unplanned pregnancy), her mother used Diclofenac. Since there is limited information regarding to teratogenic effects of diclofenac, we considered it interesting to present this case.

The purpose of this case report was to introduce the concept of orthodontic and orthopedic treatment for a growing patient with Tessier number 0 cleft. A 5-year-old boy patient with Tessier number 0 cleft presented congenitally missing maxillary central incisors (MXCI), a bony defect at the premaxilla, a constricted maxillary arch, an anterior openbite, and maxillary hypoplasia. His treatment was divided into three stages: management of the bony defect at the premaxilla and the congenitally missing MXCIs using a fan-type expansion plate, iliac bone grafting, and eruption guidance of the maxillary lateral incisors into the graft area for substitution of MXCIs; management of the maxillary hypoplasia using sequential facemask therapy with conventional and skeletal anchorage; and management of the remaining occlusal problems using fixed orthodontic treatment. The total treatment duration was 15 years and 10 months. Class I canine and Class II molar relationships and normal overbite and overjet were achieved at the end of treatment. Although the long-term use of facemask therapy resulted in significant protraction of the retrusive maxilla, the patient exhibited Class III profile because of continued mandibular growth. However, the treatment result was well maintained after 2 years of retention. The findings from this case suggest that interdisciplinary and customized approaches are mandatory for successful management of maxillary hypoplasia, bony defect, and dental problems in Tessier number 0 cleft. Moreover, considering the potential of orthognathic surgery or distraction osteogenesis, meticulous monitoring of mandibular growth until growth completion is important. PMID:29564221

Craniofacial and dental malformations in Costello syndrome: A detailed evaluation using multi-detector row computed tomography.

Costello syndrome is a rare multiple congenital anomaly syndrome caused by heterozygous germline HRAS mutations, which is characterized by intellectual disability, growth retardation, distinctive facies, loose skin, cardiomyopathy and a preposition to malignancies. Although teeth abnormalities have been encountered in nearly two-thirds of the patients in literature, the evaluation tended to be limited to the extent which can be obtained from physical examination. We investigated detailed craniofacial, oral and dental findings in four patients with Costello syndrome. In this study, images reconstructed by multi-detector row computed tomography (MDCT) were used as substitutes for dental cast study and panoramic and lateral cephalometric radiograph studies to evaluate dental arches, tooth size, relationships between craniofacial and dental structures, and hypodontia. All four patients showed true/relative macrocephaly with facial bone hypoplasia and gingival hypertrophy. Occlusal attrition, malocclusion, small dental arches, microdontia, and convex face were noted in three patients. In addition, one patient showed dental caries, conic tooth and gingivitis, and another patient showed hypodontia. Our study suggests that craniofacial and dental abnormalities are common in Costello syndrome patients and comprehensive dental care should be provided from early infancy. To our knowledge, this is the first study of thorough craniofacial and dental evaluation by using MDCT in Costello syndrome. MDCT is a useful tool for precise evaluation of craniofacial and oral manifestations in patients with congenital anomaly/intellectual disability syndromes. © 2012 The Authors.

Nowadays the use of implants as a increasing therapy in dentistry and it has become a usual treatment in dental offices. More and more dentists have dental implants included in treatment plans for patients with missing teeth. Therefore is necessary that all dentists know all the possibilities of these treatments. Together with the emergence of dental implants, it is also beginning to see an increase in the onset of lasers in dentistry. These two new techniques in dentistry can be supplemented because as we will see the use of lasers in different cases can improve implant treatment.

To compare the prevalence of dental caries in two groups of schoolchildren: (1) schoolchildren participating in a weekly 0.2% sodium fluoride mouth-rinsing program and (2) schoolchildren not participating in the program. This cross-sectional study was conducted in the city (municipality) of Londrina, in the state of Paraná, Brazil; the city has fluoridated drinking water. We examined 367 12-year-old children: 190 participants in the weekly mouth-rinsing program (51.8%) and 177 nonparticipants (48.2%). The prevalence of caries was determined based on the scores for decayed, missing, and filled teeth and for decayed, missing, and filled surfaces. The examinations were performed by three examiners, with nearly perfect agreement in their diagnosis of caries (kappa = 0.90). The dependent variable was dental caries. The independent variables were: participation or nonparticipation in the mouth-rinsing program, attending a private school or a public school, frequency of tooth-brushing, amount of toothpaste used, consumption of sweets between meals, and visits to the dentist. The decayed, missing, and filled teeth score (mean and standard deviation) at 12 years of age was 0.85 +/- 0.059 overall, 1.0 +/- 0.058 for program participants, and 0.70 +/- 0.060 for nonparticipants. The decayed, missing, and filled surfaces score (mean and standard deviation) was 1.16 +/- 0.017, with it ranging from a low of 0.34 in one private school to a high of 1.66 in one public school. Bivariate analysis showed an association between caries (P < 0.05) and the following variables: attending a public school, participating in the mouth-rinsing program, and consuming sweets between meals more than once a day. In the multivariate analysis, attending a public school (P = 0.0004) and consuming sweets (P = 0.001) remained associated with the presence of caries. The weekly mouth-rinsing program was not associated with a decreased prevalence of caries, in either the public schools or the private schools. However, additional research is needed to assess the cost-effectiveness of fluoride mouthrinsing programs in populations with a higher prevalence of caries. Given the caries prevalence that we found in the schoolchildren whom we studied, the resources allocated to the fluoride mouth-rinsing program for them should probably be used to pay for other health-promotion activities with them.

The purpose of this study was to assess the prevalence and associated factors of dental caries and periodontal diseases among 14⁻19-year-old schoolchildren with limited access to dental care services. A cross sectional study design was conducted during field visits to seven governmental schools in Al-Khomrah district, South Jeddah, over the period from September 2015 to May 2016. Clinical examinations and administered questionnaires were carried out in mobile dental clinics. The dentists carried out oral examinations using the dental caries index (DMFT), the simplified oral hygiene index (OHI-S), and the community periodontal index for treatment needs (CPITN). Statistical analyses were performed using SPSS 20. A total of 734 schoolchildren were examined. The prevalence of decayed teeth was 79.7% and was significantly higher among boys (88.9%) than girls (69.0%). About 11% of students had missing teeth, with a significantly higher figure among females than males (15.9% versus 7.3%); 19.8% of students had filled teeth. Moreover, a DMFT of seven or more was significantly more prevalent among males (43.3%) than females (26.8%), while the percentage of females with sound teeth was significantly higher than for males (20.4% and 9.6% respectively). The CPITN revealed 0, 1 and 2 scores among 14.6%, 78.2%, and 41.6% respectively. Males had a significantly higher percentage of healthy periodontal condition (23.8%) than females (3.8%). Dental caries prevalence was moderate to high, calculus and gingival bleeding were widespread among schoolchildren, and were more prevalent among students with low socioeconomic status.

Objectives The purpose of this study was to examine developmental enamel defects and dental caries in very low birth weight adolescents with high risk (HR-VLBW) and low risk (LR-VLBW) compared to full-term (term) adolescents. Methods The sample consisted of 224 subjects (80 HR-VLBW, 59 LR-VLBW, 85 term adolescents) recruited from an ongoing longitudinal study. Sociodemographic and medical information was available from birth. Dental examination of the adolescent at the 14-year visit included: enamel defects (opacity and hypoplasia); decayed, missing, filled teeth of incisors and molars (DMFT-IM) and of overall permanent teeth (DMFT); Simplified Oral Hygiene Index for debris/calculus on teeth, and sealant presence. A caregiver questionnaire completed simultaneously assessed dental behavior, access, insurance status and prevention factors. Hierarchical analysis utilized the zero-inflated negative binomial model and zero-inflated Poisson model. Results The zero-inflated negative binomial model controlling for sociodemographic variables indicated that the LR-VLBW group had an estimated 75% increase (p < 0.05) in number of demarcated opacities in the incisors and first molar teeth compared to the term group. Hierarchical modeling indicated that demarcated opacities were a significant predictor of DMFT-IM after control for relevant covariates. The term adolescents had significantly increased DMFT-IM and DMFT scores compared to the LR-VLBW adolescents. Conclusion LR-VLBW was a significant risk factor for increased enamel defects in the permanent incisors and first molars. Term children had increased caries compared to the LR-VLBW group. The effect of birth group and enamel defects on caries has to be investigated longitudinally from birth. PMID:20975268

The aim of this study was to investigate dental disorders of brown howler monkeys maintained in captivity. The hypothesis is that the identification and diagnosis of the lesions may contribute to control and prevention. Sixteen intact brown howler monkeys (Alouatta guariba clamitans), eight females and eight males, weighing from 3.9 to 6.8 kg, were studied. Under general anesthesia, the teeth were evaluated by visual inspection, probing, palpation, and intra-oral radiographic exam. The findings were registered on a dental chart specific for primates. Of the 16 monkeys evaluated in the present study, 94% (n = 15) had some type of dental disorder. The lesions observed were dental calculus (88%), dental wear (81%), missing teeth (38%), gingivitis (19%), gingival recession (6%), dental fracture (19%), pulp exposure (19%), and dental staining (25%). Alouatta guariba clamitans maintained in captivity have a high rate of dental problems. © 2016 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

Verify factors that influence the oral health status of people living with HIV/AIDS (PLWHA) in Brazil. The study was cross-sectional and includes 177 HIV-positive individuals, who answered questionnaire on the sociodemographic conditions, HIV aspects, habits, and satisfaction with the service. The oral health data were collected by means of the decayed, missing, and filled teeth (DMFT) index, use and need of dentures, and the Community Periodontal Index. Average number of the DMFT was 17.64. Most HIV-positive patients presented good periodontal status, 35.0% used dentures, 41.5% needed denture in the maxilla, and 62.0% in the mandible. In the multivariate analysis, older age and dissatisfaction with health care were associated with nonuse of dentures. The abandonment of the use of antiretroviral therapy increased the risk of PLWHA presenting more than three decayed teeth. Poor oral health of the PLWHA was mainly influenced by sociodemographic factors and use and satisfaction with service. © 2014 Special Care Dentistry Association and Wiley Periodicals, Inc.

Eight adult (six male and two female) wild Qinling giant pandas (Ailuropoda melanoleuca qinlingensis) from China National Foping Nature Reserve were tracked, and their dental data collected and recorded from October 2010 to April 2014. Each panda had dental abnormalities of varying severity. Dental wear and fracture were the most common conditions. Absent teeth were common, with premolars missing most often. Mild caries were present in five molar teeth between two animals. Different degrees of dental plaque and calculus occurred in all animals but without severe periodontal disease. Two animals with severe dental abnormalities died due to intestinal problems. Large segments of bamboo were found in their intestinal tracts, and intestinal perforation and ulcers were evident, indicating dental abnormalities can be an important factor in the health of wild giant pandas and may lead to death. Further research with larger sample sizes of wild and captive giant pandas will be required to substantiate the relationship between dental abnormalities and mortality in giant pandas.

As of August 2014, the Joint POW/MIA Accounting Command has identified the remains of 1980 previously unknown U.S. service members; 280 were from the Korean War. To determine the accuracy and completeness of the available antemortem (AM) dental records, a review of the AM/postmortem (AM/PM) dental record comparisons from 233 Forensic Odontology Reports written in support of remains identified from the Korean War was performed. Seventy-two AM/PM comparisons resulted in exact dental chartings while 161 contained discrepancies which were explainable. Explainable discrepancies include undocumented treatment (103), incorrectly charted third molars as missing (82), differing opinions of specific molars present/missing (20), and erroneous treatment documentation and/or misidentification of teeth present/missing (22, other than molars). Reassessment has revealed varying levels of completeness for our available AM dental records, the need to thoroughly review our computerized comparisons, adjust our comparisons to include molar pattern variations/third molars, and updating our database comparison program.

Origins of thalamic and cortical projections to the posterior auditory field in congenitally deaf cats.

Butler, Blake E; Chabot, Nicole; Kral, Andrej; Lomber, Stephen G

2017-01-01

Crossmodal plasticity takes place following sensory loss, such that areas that normally process the missing modality are reorganized to provide compensatory function in the remaining sensory systems. For example, congenitally deaf cats outperform normal hearing animals on localization of visual stimuli presented in the periphery, and this advantage has been shown to be mediated by the posterior auditory field (PAF). In order to determine the nature of the anatomical differences that underlie this phenomenon, we injected a retrograde tracer into PAF of congenitally deaf animals and quantified the thalamic and cortical projections to this field. The pattern of projections from areas throughout the brain was determined to be qualitatively similar to that previously demonstrated in normal hearing animals, but with twice as many projections arising from non-auditory cortical areas. In addition, small ectopic projections were observed from a number of fields in visual cortex, including areas 19, 20a, 20b, and 21b, and area 7 of parietal cortex. These areas did not show projections to PAF in cats deafened ototoxically near the onset of hearing, and provide a possible mechanism for crossmodal reorganization of PAF. These, along with the possible contributions of other mechanisms, are considered. Copyright © 2016 Elsevier B.V. All rights reserved.

Congenital erythropoietic porphyria (Gunther's disease, GD) is a rare autosomal recessive disease. It results from the deficiency of uroporphyrinogen III synthase, the fourth enzyme on the metabolic pathway of heme synthesis. GD leads to severe scarring of the face and hands as a result of photosensitivity and fragility of the skin due to uroporphyrin I and coproporphyrin I accumulation. It also causes erythrocyte fragility leading to haemolytic anaemia. The other clinical features include hirsutism, red discolouration of teeth, finger-nails and urine and stunted growth. The outcome is poor, and the disfiguring nature of GD may partly explain the legend of the werewolf. No curative treatment was known until 1991, when the first case of BMT in GD was reported. The clinical and biological outcome after transplantation was encouraging, with an important regression of the symptoms of the disease, but the child died of CMV-infection 11 months after BMT. We report the second case of GD treated successfully by stem cell transplantation using umbilical cord blood from an HLA-identical brother in a 4-year-old girl suffering from severe GD. Our patient is very well 10 months after transplantation. We confirm that stem cell transplantation is curative for GD.

Assessment of Myeloperoxidase and Nitric Levels around Dental Implants and Natural Teeth as a Marker of Inflammation: A Comparative Study.

Dental implants form the mainstay of dental treatment involving rehabilitation of missing teeth. One of the major concerns for the clinicians doing dental implants is the postsurgical failure of dental implants. Success of dental implants is dependent upon the skills of the surgeon and the amount and quality of the bone remaining at the edentulous area where dental implant has to be placed. Myeloperoxidase (MPO) and nitrites are few of the enzymes and molecules which are said to be altered in inflammation. However, their exact role in the inflammatory processes around natural tooth and dental implant is still unclear. Hence we comparatively evaluated the levels of MPO and nitrites in the areas around the dental implants and natural teeth. The present study comprises 42 patients who underwent prosthetic rehabilitation by dental implants from 2011 to 2014. Depth of probing value (DP), score of plaque index (SPI), gingival index (GI), and index of gingival bleeding time (GBT) were evaluated for the assessment of the periimplant soft tissue changes. Assessment of inflammation around the dental implant surface and around natural tooth was done based on the readings of these parameters. For the measurement of the MPO levels, spectrophotometric MPO assay was used. All the results were analyzed by Statistical Package for the Social Sciences (SPSS) software. The mean plaque index values were 1.56 and 0.97 in periodontitis cases of natural teeth and inflamed cases of dental implants respectively. While comparing mean plaque index, mean probing depth, and mean gingival bleeding index in between the two groups, significant difference was obtained. Mean MPO concentration in periodontitis and gingivitis cases in natural teeth were 0.683 and 0.875 U/μL, while in inflamed dental implant cases, the mean value was 0.622 U/μL. While comparing the total MPO levels, total nitrite levels, and total nitrite concentration in between two study groups, significant difference was obtained. On comparing the healthy and periodontitis cases in natural teeth, significant difference was obtained. In the inflammatory processes occurring around dental implant and natural teeth, MPO and NO make some amount of significant contribution. The present study enforces on the role of MPO and nitrite as diagnostic and prognostic marker.

The first goal of this research was to perceive the global commitment towards the organization and archiving of dental records and to compare it with each country's security risk rating. The second one was to study dental records in a sample of the Portuguese military population, using the available national dental records. An e-mail was sent to representative dentistry associations in several countries, requesting some information concerning the professionals' awareness of this issue. After obtaining permission from the Ethics Committee, the information was collected through the Forensic Dental Symbols® system into the Dental Encoder®, as an extension of a Spanish study, and a generic codification was used (unrestored, restored, missing and crowned teeth). The most common dental record retention period is ten years after treatment. Observing the samples' dental records (595 files), we found a total of 19 040 analyzed teeth, with the following frequencies: unrestored (89.6%), restored (7.0%), missing (2.2%) and crowned (1.1%). There is a wide range of guidelines on how long dentists should keep dental records. Especially for the military population, dental records must include detailed information concerning each tooth situation, in order to support the process of human identification. This article reinforces the need for mandatory quality dental records in all countries, which must be efficiently stored and easily accessible in case dental identification is necessary. For the military population, these requirements are especially important, due to the added risks to which this group is subject.

The authors conducted an analysis of data from the National Health and Nutrition Examination Survey (NHANES) to understand the association between diabetes and tooth loss in the United States. The authors analyzed the oral examination and self-reported diabetes data obtained from the NHANES 2003-2004 cycle and included 2,508 participants representing a civilian, noninstitutionalized U.S. population 50 years and older. The authors calculated the prevalence of edentulism and the number of missing teeth among dentate people, and they used multiple regression analyses to assess the association between diabetes and tooth loss. The prevalence of edentulism was 28 percent and 14 percent among people with and without diabetes, respectively. The multiple logistic regression analysis revealed that people with diabetes were more likely to be edentulous than were those without diabetes (adjusted odds ratio = 2.25; 95 percent confidence interval, 1.19-4.21). Among dentate adults, those with diabetes had a higher number of missing teeth than did adults without diabetes (mean [standard error {SE}] = 9.8 [0.67]), mean [SE] = 6.7 [0.29]); P < .01). These study results revealed that adults with diabetes are at higher risk of experiencing tooth loss and edentulism than are adults without diabetes. One of every five cases of edentulism in the United States is linked to diabetes. Practical Implications. Although the association between diabetes and periodontal disease is well established, health care professionals also need to recognize the risk of tooth loss and its effect on quality of life among people with diabetes.

Although in today's dental world implant restorations are considered the standard of care in the replacement of missing teeth, clinical contraindications and patient nonacceptance of implant placement can be encountered. Several scenarios are discussed here in which a single missing tooth can be restored with conservative fixed partial dentures (FPD) that employ cast gold retainers; each with a customized design in order to preserve tooth structure, maintain esthetics, and provide a long-term prognosis. The abutment teeth are prepared for conservative partial coverage restorations by using Brasseler burs (Brasseler USA, Savannah, GA, USA). Impressions are taken of the preparations, along with any retentive features, utilizing either the Vented Pin Channel technique or the Shooshan Plastic Pin technique. The latter technique utilizes Kodex twist drills and corresponding impression pins (Coltene Whaledent Inc., Mahwah, NJ, USA). The conservative FPD with non-rigid connectors is fabricated by using type III gold alloy. The pontic cage portion is chemically prepared utilizing the Panavia F2.0 cement kit (Kuraray America Inc., Houston, TX, USA) or other dual-polymerizing resin cement and restored with any type of direct composite resin material. A palette of opaquers and tints are used for chairside characterization of the esthetic pontic facing. The final polish of the pontic is completed by using FlexiDisc and FlexiBuff discs (Cosmedent Inc., Chicago, IL, USA). CLINICAL SIGNIFICANCE In cases where an implant restoration is contraindicated for replacement of a single tooth, a semi-precision FPD is a conservative, functional, and esthetic alternative.

Surgical-orthodontic treatment of patients suffering from severe periodontal disorders - a clinical case study.

Orthodontic or, more precisely, surgico-orthodontic treatment of patients suffering from periodontal disorders generally requires a multidisciplinary approach by a qualified dental team. Periodontal bone healing is an essential factor for successful orthodontic treatment in a compromised periodontal situation. We report on the case of an adult patient suffering from severe chronic periodontitis; he was a hyperdivergent skeletal Class III with dento-alveolar compensation, esthetic problems and a significant lack of dental material. A multidisciplinary approach was adopted. First of all, periodontal treatment was undertaken (root scaling and planing) accompanied by appropriate medical treatment and a bone graft to strengthen the area of the lower incisors. After that, surgical and orthodontic treatment to correct the malocclusion was begun. The difficulty lay in the significant absence of dental material to ensure proper intercuspation. A surgical repositioning splint was constructed on an articulator to ensure adequate mandibular retraction after maxillary advancement surgery. After treatment, the missing teeth were replaced by a prosthesis. Following treatment, the periodontal bone resorption was stabilized; the bone deficit was improved and the malocclusion had been corrected; the missing teeth were replaced by appropriate dentures. Short- and medium-term follow-up confirmed the stability of the results obtained, which will be discussed. The right combination of properly managed orthodontic, periodontal and prosthetic treatment can contribute to effective elimination of chronic periodontitis, even at an advanced stage in an adult patient, while at the same time improving esthetic and functional parameters.

The purpose of this study was to evaluate the oral health status and dental needs of the athletes with intellectual disabilities from Latin-American and Caribbean countries who were participating in the II Latin-American Special Olympics games held in Puerto Rico, February 2010. There were 930 athletes who participated in the games, of whom 445 received a dental examination, including 367 from Latin-American and 78 from Caribbean countries. Forty-four trained and standardized dental professionals performed dental screenings of athletes with intellectual disabilities, following Special Olympic Special Smiles and CDC protocols. These criteria were used to record untreated caries, missing and filled teeth, and gingival status. Socio-demographics, existence, and severity of pain and oral hygiene habits were assessed by questionnaire. Statistical analysis was performed using EPI-INFO and SPSS Statistical Program to produce descriptive statistics and chi-square test. Untreated dental caries was recorded for more than half of the examined athletes. Missing teeth were noted in more than one-third of the athletes. More than half of the participants had signs of gingival disease and half needed preventive mouth guards. Statistics for each Latin-American country suggests a dissimilar trend of dental decay and treatment needs among nations. While the Special Olympic athletes may not be representative of the entire population of individuals with intellectual disabilities in their specific country, the general consistency of the oral health status of these athletes from the 31 countries supports the certainty of the need for increased dental services for individuals with intellectual disability in the respective countries. ©2013 Special Care Dentistry Association and Wiley Periodicals, Inc.

The benefit of a public sector sealant programme for children in Australia is yet to be established. This study evaluated sealants placed by therapists of the School Dental Service in Victoria, between 1989 and 1994, on permanent teeth of children in 15 primary schools in Melbourne. Seven hundred and seventy four children aged 6-12 years were examined in school dental clinics by six calibrated examiners. A total of 5363 sealants placed on 2875 permanent teeth (including 2616 first molars, 91 per cent of sample) up to four and a half years previously was examined. Values for complete and partial sealant retention were highest for premolars (86 per cent, 9 per cent respectively, total 95 per cent); similar for occlusal surfaces of maxillary and mandibular first molars (63 per cent, 30 per cent; 62 per cent, 32 per cent respectively) and buccal pits of mandibular molars (66 per cent); and low for pits/fissures of Carabelli's cusps of maxillary molars (44 per cent). Cross-sectional examination up to 24 months for both maxillary and mandibular first molars indicated average values of 67 per cent complete retention, 27 per cent partial retention, 6 per cent missing; thereafter complete retention decreased and partial retention increased. Sealant failures in the six months post-placement were attributed to technique failure. Regardless of sealant retention, caries experience was low under partially retained or missing sealants (4.5 per cent) and completely retained sealants (0.4 per cent). It is concluded that the SDS sealant programme is a sound preventive dental public health approach.

Influence of self-esteem and negative affectivity on oral health-related quality of life in patients with partial tooth loss.

To meaningfully interpret oral health-related quality of life (OHRQoL) measures, the influence of personality traits must be investigated. To investigate and quantify the influence of self-esteem and negative affectivity (NA) on OHRQoL. It was hypothesized that low self-esteem and high NA would be associated with worse OHRQoL. OHRQoL measured by the Oral Health Impact Profile 49 (OHIP-49), self-esteem measured by the Rosenberg Self-Esteem Scale (RSES), NA measured by the Eysenck Personality Inventory Questionnaire (EPI-Q), global oral rating of oral comfort and controlling variables (gender, age, number of teeth, experience of wearing removable dental prostheses (RDP), location of missing teeth and zone of missing teeth) were collected from 81 patients with partial tooth loss, signed in for treatment with RDP. Bivariate analyses showed that the EPI-Q score had the highest correlation with OHIP-49 score (R = 0.5). Both EPI-Q and RSES score had a stronger correlation with psychosocial items than physical/functional items of the OHIP-49. In the multivariate analyses, the controlling variables alone explained 17.75% of the variance in OHIP-49 score, while addition of EPI-Q score, RSES score and both EPI-Q and RSES score explained additionally 11.64%, 6.07% and 14.12%, respectively. For each unit increase in EPI-Q score, the OHIP-49 score increased 5.1 units and for each unit increase in RSES score, the OHIP-49 score decreased 1.1. NA was statistically and clinically significantly higher and self-esteem was statistically significantly lower in patients reporting worse oral comfort. NA had the strongest and most clinically meaningful influence, but both NA and self-esteem was found to influence OHRQoL; low self-esteem and high NA was associated with worse OHRQoL. This indicates the possibility to explain some of the impact of tooth loss on OHRQoL based on personality traits. © 2012 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

To assess the impact of children's dental health status (DHS) on their oral health-related quality of life (OHRQoL). Participants were 11- and 12-year-old children attending public schools in the Kuwait Capital Region. Children's DHS was evaluated by clinical examinations and presented using decayed, missed, filled teeth/surface (DMFT/dmft, DMFS/dmfs); restorative (RI), plaque (PI); and pulp, ulcers, fistula, abscess (PUFA) indices. Children's OHRQoL was assessed using Child's Perception Questionnaire 11-14 (CPQ11-14). Means (SD) and frequencies were used for data description. Different factors were analyzed as predictors of OHRQoL by logistic regression analysis. A total of 440 children aged 11-12 years (50.7 % females) participated in this cross-sectional study. Mean (SD) DMFT/dmft, RI, PI, and PUFA scores were 2.91(2.75), 0.21 (0.34), 3.59 (1.63), 0.31 (0.85), respectively. The mean total CPQ11-14 was 20.72 (16.81). Mean scores of oral-symptoms, functional-limitations, emotional and social well-being were 4.26 (3.32), 5.40 (4.92), 5.48 (6.15), and 5.33 (6.05), respectively. Children with more than four fillings were 95 % less likely to have had oral symptoms than those with no fillings. Children with a DMFT/dmft of 2-3 were 2.8 times more likely to have functional limitation than those with a DMFT/dmft of 0, while children with a DMFT/dmft of more than 4 were 4.4 times more likely to experience limitations. Having two or three non-cavitated lesions reduced the odds of having functional-limitation by 58 %. Children with more than four missing teeth were 45 % more likely to experience emotional stress. Having more than four fissure sealants reduced the odds of having emotional stress by 46 %. The increase in the number of carious teeth was associated with a limitation in oral functions. Preventive treatment had a positive impact on children's emotional well-being and restorative treatments improved their oral function.

Due to its severity, as well as the consequences of a late diagnosis, critical congenital heart defects (CCHD) represent a challenging situation, making an early diagnosis necessary and ideally before symptoms appear when circulatory collapse or death of the newborn can occur. Due to this, a prenatal and very early postnatal diagnosis is very important. Prenatal ultrasound screening and physical examination of the newborn can miss a considerable number of CCHD cases. Pulse oximetry screening has been demonstrated to be an effective, non-invasive, inexpensive, and well accepted tool in the early diagnosis of CCHD. The Spanish National Society of Neonatology, through its Standards Committee, and based on the current evidence, recommend the implementation of pulse oximetry screening of CCHD in Spain, and then to offer the best therapy possible to these newborn infants.

Despite the need for oral health morbidity surveys to aid in reviewing of the oral health services, dental data of Ugandan children is scanty. To describe the magnitude and distribution of selected oral health conditions among primary school children in Mbarara, Uganda. A stratified two-stage cluster sample of 437 children aged 5-6, 8-9 and 11-12 was enrolled. The selected conditions included: dental caries, plaque, calculus, gingivitis, fluorosis and malocclusion (maxillary overjet). These conditions were diagnosed and scored in accordance with World Health Organisation (WHO) criteria. The mean decayed, missing, filled permanent teeth (DMFT) was 1.5(±0.8 SD). Females had higher DMFT (1.6±0.8SD) than males (1.3±0.8SD). Decayed, filled milk teeth (dt) was 2.7(±1.8SD) but more in males 3.1(±2.1SD) than in females 2.4(±1.6SD). Children in private schools were likely to have more caries in both permanent teeth (DMFT: 1.6±0.9SD) and milk teeth (dt: 3.0±1.9SD). Day-scholars were likely to have more caries in permanent teeth (DFMT: 1.50.8SD). Those in boarding were likely to have more caries in milk teeth (dt: 3±2.2SD). Milk teeth caries decreased with age (p<0.0001). Eight (1.8%) had very mild to moderate fluorosis. Nine (2%) lost permanent canines due to practice of "nylon teeth mutilation." Majority 325(75%) had dental plaque, which increased with age (p<0.0001). Males significantly had plaque. Children in private schools were associated with less plaque (OR: 0.6, 95%CI: 0.4-0.9), as were those in boarding schools. Some 113(25.9%) had calculus that increased with age (p<0.0001). Calculus was more prevalent in males, government schools, and among day-scholars. Females were less likely to have maxillary overjet (OR: 0.5, 95% CI: 0.3-0.8). Day-scholars were 2 times more likely to have maxillary overjet (OR: 1.9, 95%CI: 1.1-3.5). None had severe gingivitis. The oral hygiene of school children was poor with high plaque prevalence demonstrating a lack of established oral hygiene practices. A comprehensive community-focused oral health care intervention that includes oral health education in homes and the strengthening of school health programme is needed to improve the oral health status of children in Mbarara.

To examine the pattern of injuries in cases of fatal shark attack in South Australian waters, the authors examined the files of their institution for all cases of shark attack in which full autopsies had been performed over the past 25 years, from 1974 to 1998. Of the seven deaths attributed to shark attack during this period, full autopsies were performed in only two cases. In the remaining five cases, bodies either had not been found or were incomplete. Case 1 was a 27-year-old male surfer who had been attacked by a shark. At autopsy, the main areas of injury involved the right thigh, which displayed characteristic teeth marks, extensive soft tissue damage, and incision of the femoral artery. There were also incised wounds of the right wrist. Bony injury was minimal, and no shark teeth were recovered. Case 2 was a 26-year-old male diver who had been attacked by a shark. At autopsy, the main areas of injury involved the left thigh and lower leg, which displayed characteristic teeth marks, extensive soft tissue damage, and incised wounds of the femoral artery and vein. There was also soft tissue trauma to the left wrist, with transection of the radial artery and vein. Bony injury was minimal, and no shark teeth were recovered. In both cases, death resulted from exsanguination following a similar pattern of soft tissue and vascular damage to a leg and arm. This type of injury is in keeping with predator attack from underneath or behind, with the most severe injuries involving one leg. Less severe injuries to the arms may have occurred during the ensuing struggle. Reconstruction of the damaged limb in case 2 by sewing together skin, soft tissue, and muscle bundles not only revealed that no soft tissue was missing but also gave a clearer picture of the pattern of teeth marks, direction of the attack, and species of predator.

Prevalence of dental developmental anomalies of permanent teeth in children and their influence on esthetics.

The aim of this study was to determine the prevalence of dental developmental anomalies in permanent teeth and their influence on esthetics. The records of 473 subjects, which comprised of orthopantomograms, clinical examination, and anamnestic data, were explored for dental developmental anomalies. Subjects with dental anomalies completed the modified questionnaire. Data on reasons for seeking the treatment as well as factors affecting the patients' satisfaction were collected. The data were processed using the Chi-square test. It was found that 79 subjects (16.7%) had at least 1 dental developmental anomaly. The most common anomalies were hypodontia (7.2%), followed by talon cusps (3.4%), and microdontia (2.5%). Hypodontia, microdontia, and talon cusps were found more prevalent in females than males, whereas hyperdontia and macrodontia were more common in males. The reason for dissatisfaction with their smile in most cases was due to missing teeth or spacing between anterior teeth (excess space 2.9 mm ± 1.1 mm), followed by crowding of anterior teeth (lack of space 3.1 mm ± 0.8mm), difficulty maintaining oral hygiene and midline asymmetry (1.8 mm ± 0.9 mm). All subjects were treated using a fixed orthodontic appliance and 30 (37.9%) of them had additional dental specialists included to achieve good esthetics and function. Overall, 92.4% of subjects were satisfied with their resulting appearance after treatment. Dental developmental anomalies are clinically evident abnormalities. They may be the cause of various dental problems and can influence esthetics and the development of orthodontic problems. This paper evaluates the distribution of dental developmental anomalies and their influence on esthetics and function. Careful observation and appropriate investigation are required to diagnose the condition and institute treatment. The therapeutic approach to some dental anomalies should be interdisciplinary. © 2017 Wiley Periodicals, Inc.

Periodontal disease may increase the risk of adverse birth outcomes; however, results have been mixed. Few studies have examined periodontal disease in developing countries. We describe the relationship between periodontal disease and birth outcomes in a community setting in Pakistan. This was a prospective cohort study. Enrollment occurred at 20-26 weeks of gestation. A study dentist performed the periodontal examination to assess probing depth, clinical attachment level, gingival index, and plaque index. Outcomes included stillbirth, neonatal death, perinatal death, < 32 weeks preterm birth, 32-36 weeks preterm birth, and low birthweight and are presented for increasing periodontal disease severity by quartiles. Dental examinations and outcome data were completed for 1152 women: 81% of the women were multiparous, with a mean age of 27 years; 33% of the women had no education. Forty-seven percent of the women had dental caries; 27% of the women had missing teeth, and 91% of the women had had no dental care in the last year. Periodontal disease was common: 76% of the women had > or = 3 teeth with a probing depth of > or = 3 mm; 87% of the women had > or = 4 teeth with a clinical attachment level of > or = 3 mm; 56% of the women had > or = 4 teeth with a plaque index of 3; and 60% of the women had > or = 4 teeth with a gingival index of 3. As the measures of periodontal disease increased from the 1st to 4th quartile, stillbirth and neonatal and perinatal death also increased, with relative risks of approximately 1.3. Early preterm birth increased, but the results were not significant. Late preterm birth and low birthweight were not related to measures of periodontal disease. Pregnant Pakistani women have high levels of moderate-to-severe dental disease. Stillbirth and neonatal and perinatal deaths increased with the severity of periodontal disease.

The objective of this study was to test the validity of the pragmatic criteria of the definitions of neonatal near miss, extending them throughout the infant period, and to estimate the indicators of perinatal care in public maternity hospitals. A cohort of live births from six maternity hospitals in the municipalities of São Paulo, Niterói, and Rio de Janeiro, Brazil, was carried out in 2011. We carried out interviews and checked prenatal cards and medical records. We compared the pragmatic criteria (birth weight, gestational age, and 5' Apgar score) of the definitions of near miss of Pileggi et al., Pileggi-Castro et al., Souza et al., and Silva et al. We calculated sensitivity, specificity (gold standard: infant mortality), percentage of deaths among newborns with life-threatening conditions, and rates of near miss, mortality, and severe outcomes per 1,000 live births. A total 7,315 newborns were analyzed (completeness of information > 99%). The sensitivity of the definition of Pileggi-Castro et al. was higher, resulting in a higher number of cases of near miss, Souza et al. presented lower value, and Pileggi et al. and de Silva et al. presented intermediate values. There is an increase in sensitivity when the period goes from 0-6 to 0-27 days, and there is a decrease when it goes to 0-364 days. Specificities were high (≥ 97%) and above sensitivities (54% to 77%). One maternity hospital in São Paulo and one in Niterói presented, respectively, the lowest and highest rates of infant mortality, near miss, and frequency of births with life-threatening conditions, regardless of the definition. The definitions of near miss based exclusively on pragmatic criteria are valid and can be used for monitoring purposes. Based on the perinatal literature, the cutoff points adopted by Silva et al. were more appropriate. Periodic studies could apply a more complete definition, incorporating clinical, laboratory, and management criteria, including congenital anomalies predictive of infant mortality.

In 2011, the US Secretary of Health and Human Services recommended universal screening of newborns for critical congenital heart defects (CCHDs), yet few estimates of the number of infants with CCHDs likely to be detected through universal screening exist. Our objective was to estimate the number of infants with nonsyndromic CCHDs in the United States likely to be detected (true positives) and missed (false negatives) through universal newborn CCHD screening. We developed a simulation model based on estimates of birth prevalence, prenatal diagnosis, late detection, and sensitivity of newborn CCHD screening through pulse oximetry to estimate the number of true-positive and false-negative nonsyndromic cases of the 7 primary and 5 secondary CCHD screening targets identified through screening. We estimated that 875 (95% uncertainty interval [UI]: 705-1060) US infants with nonsyndromic CCHDs, including 470 (95% UI: 360-585) infants with primary CCHD screening targets, will be detected annually through newborn CCHD screening. An additional 880 (UI: 700-1080) false-negative screenings, including 280 (95% UI: 195-385) among primary screening targets, are expected. We estimated that similar numbers of CCHDs would be detected under scenarios comparing "lower" (∼19%) and "higher" (∼41%) than current prenatal detection prevalences. A substantial number of nonsyndromic CCHD cases are likely to be detected through universal CCHD screening; however, an equal number of false-negative screenings, primarily among secondary targets of screening, are likely to occur. Future efforts should document the true impact of CCHD screening in practice. Copyright © 2015 by the American Academy of Pediatrics.

2009-03-01

This cross-sectional study assessed associations between nutrition and dental caries in permanent dentition and identified oral hygiene indicators among older children aged 12-14 years in primary schools in Thailand. The study was comprised of 862 schoolchildren from five provinces representing five regions of Thailand, from both rural and urban areas, including Bangkok. The dental hygeine status was assessed by evaluating for decayed teeth, missing teeth due to decay, and filled teeth index (DMFT index). Weight and height were measured to evaluate the nutritional status; hygiene practices assessed by interview. The results show a negative relationship between nutritional status and the DMFT index, which increased when the nutritional status decreased (Spearman's rho correlation = -0.140, p < 0.001). The results from multiple logistic regression analysis showed normal weight and thin schoolchildren were more likely to have a DMFT of at least 1 by 1.94 times (OR = 1.94; 95%CI = 1.25-3.00, p = 0.004) and 2.22 times (OR = 2.22; 95%CI = 1.20-4.09, p = 0.001), respectively, compared to overweight and obese children. Normal and thin schoolchildren had a higher risk for dental caries than overweight and obese children aged 12-14 years in Thailand. School health promotion activities should emphasize eating habit improvement in order to reduce the incidence of caries.

Most Medicaid programs reimburse nondental providers for preventive dental services. We estimate the impact of comprehensive preventive oral health services (POHS) on dental caries among kindergarten students, hypothesizing improved oral health among students with medical visits with POHS. We conducted a retrospective study in 29,173 kindergarten students by linking Medicaid claims (1999-2006) with public health surveillance data (2005-2006). Zero-inflated regression models estimated the association between number of visits with POHS and (1) decayed, missing, and filled primary teeth (dmft) and (2) untreated decayed teeth while adjusting for confounding. Kindergarten students with ≥4 POHS visits averaged an adjusted 1.82 dmft (95% confidence interval: 1.55 to 2.09), which was significantly less than students with 0 visits (2.21 dmft; 95% confidence interval: 2.16 to 2.25). The mean number of untreated decayed teeth was not reduced for students with ≥4 POHS visits compared with those with 0 visits. POHS provided by nondental providers in medical settings were associated with a reduction in caries experience in young children but were not associated with improvement in subsequent use of treatment services in dental settings. Efforts to promote oral health in medical settings should continue. Strategies to promote physician-dentist collaborations are needed to improve continuity of care for children receiving dental services in medical settings.

Childhood factors such as low socioeconomic status are risk factors for Helicobacter pylori infection and Streptococcus mutans-related dental caries. We examined whether H. pylori infection and dental caries are present today in the same group of children examined previously. We reviewed the public dental health service files of 21 H. pylori-positive children (upper gastrointestinal endoscopy at a median age of 13.5 y) and 27 H. pylori-negative children (endoscopy at a median age of 12.5 y) examined during 1995-98 at the Helsinki University Central Hospital, Finland. All H. pylori-positive children had experienced dental caries in their primary or permanent teeth or in both whereas among H. pylori-negative children the respective proportion was 70% (p < 0.01). At the age of 7 y, 18% (3/17) of the H. pylori-positive children had experienced caries in permanent teeth as compared to 0% among H. pylori-negative children (0/24; p < 0.05). At the age of 12 y, H. pylori-positive children had more decayed, missing or filled permanent teeth than H. pylori-negative children (80% vs. 38%; p < 0.05). Although a causal relationship between H. pylori and dental caries is unlikely, it is possible that H. pylori-infected children have an increased risk of other health problems, such as dental caries, for which proper treatment is needed.

The aim of this study was to determine self-perception of oral-health in institutionalized elderly, and look into the sociodemographic and clinical aspects associated with negative self-perception. One hundred and sixty-six elderly were assessed by answering a self-perception question that predicts the GOHAI (Geriatric Oral Health Assessment Index). Sociodemographic data was obtained from a previously validated questionnaire and clinical data taken from the WHO file and QST-TMD used to check the existence of TMD (temporomandibular disturbance). The data gathered was submitted to Mann-Whitney, Fisher's Exact and Chi-squared tests with a 5% significance level. The average age of the study population was 80.5, and 75.9% were women. The mean DMFT (decayed, missing, and filled teeth in permanent teeth) was 28.9, the majority of the sample subject (65%) reported good to excellent teeth, gums and prostheses (dentures and bridges). Three questions in the TMD questionnaire (QST-DTM) were associated with negative self-perception. Those claiming that their jaws "lock" when they open or close their mouth, who always have pain at the front or side of their jaw, or whose jaws get tired during the course of the day are less satisfied with their oral health. We conclude that clinical and sociodemographic conditions have little influence on self-perception of oral health, possibly because pain is the main factor associated with negative self-perception in these individuals.

Dental caries is a multifactorial disease which has a deleterious effect on the oral cavity. Improper oral hygiene habits are a cause for the same. The aim of this study was to compare the antibacterial efficacy of Munident, an Ayurvedic (herbal) dentifrice with commercially available toothpaste. A total of forty subjects between the age group 9 and 12 years, resident of Bala Yeshu Nilaya Bhavan, Mangalore, Karnataka, India, were chosen for our study. They were divided into two groups containing twenty subjects in each; Group 1 for standard toothpaste and Group 2 for Munident. The decayed, missing, and filled teeth scores were noted from each subject. Group 1 was instructed to brush the teeth using commercially available toothpaste and Group 2 was instructed to brush using commercially available Munident (herbal) dentifrice. Both the groups brushed the teeth using soft variety of tooth brush. The gingival bleeding index and salivary Streptococcus mutans count were noted pre- and post-brushimg for both groups. The results obtained were subjected to statistical analysis. Munident (herbal) dentifrice showed better efficacy in comparison to toothpaste in terms of gingival bleeding index and salivary S. mutans count. Munident (herbal) dentifrice has better gingival bleeding index compared to standard formulation of toothpaste. Hence, the practice of using herbal dentifrice should be encouraged.

The enamelin gene (ENAM) polymorphism (rs12640848) was recently associated with dental caries in primary teeth in Polish children. The aims of the present study were to prove this association in primary dentition and to find a possible effect of this variant on caries development in permanent dentition in Czech children. This study comprised 905 Czech children. Totally, 187 children aged 2-6 years with primary dentition [78 healthy subjects (with decayed/missing/filled teeth, dmft = 0) and 109 patients with early childhood caries (ECC; dmft ≥ 1)] were included in this case-control study. In addition, 177 subjects aged 13-15 years without caries (DMFT = 0) and 541 children with dental caries (DMFT ≥ 1) in permanent dentition were selected from the ELSPAC study. Genotype determination of the ENAM polymorphism (rs12640848) was based on the TaqMan method. No significant differences in the allele or genotype frequencies between the caries-free children and those affected by dental caries were observed in both primary and permanent dentitions. Lack of association between the ENAM polymorphism (rs12640848) and dental caries in Czech children was detected. Although ENAM is considered as a candidate gene for dental caries, the presence of the ENAM variant (rs12640848) cannot be used as a risk factor of this multifactorial disease in the Czech population.

Medical malpractice is the primary method by which people who believe they have suffered an injury in the course of medical care seek compensation in the United States and Canada. An increasing body of research demonstrates that failure to correctly diagnose is the most common allegation made in malpractice claims against radiologists. Since the 1994 survey by the Society of Chairmen of Radiology in Children's Hospitals (SCORCH), no other published studies have specifically examined the frequency or clinical context of malpractice claims against pediatric radiologists or arising from pediatric imaging interpretation. We hypothesize that the frequency, character and outcome of malpractice claims made against pediatric radiologists differ from those seen in general radiology practice. We searched the Controlled Risk Insurance Co. (CRICO) Strategies' Comparative Benchmarking System (CBS), a private repository of approximately 350,000 open and closed medical malpractice claims in the United States, for claims related to pediatric radiology. We further queried these cases for the major allegation, the clinical environment in which the claim arose, the clinical severity of the alleged injury, indemnity paid (if payment was made), primary imaging modality involved (if applicable) and primary International Classification of Diseases, 9th revision (ICD-9) diagnosis underlying the claim. There were a total of 27,056 fully coded claims of medical malpractice in the CBS database in the 5-year period between Jan. 1, 2010, and Dec. 31, 2014. Of these, 1,472 cases (5.4%) involved patients younger than 18 years. Radiology was the primary service responsible for 71/1,472 (4.8%) pediatric cases. There were statistically significant differences in average payout for pediatric radiology claims ($314,671) compared to adult radiology claims ($174,033). The allegations were primarily diagnosis-related in 70% of pediatric radiology claims. The most common imaging modality implicated in pediatric radiology claims was radiography. The highest payouts in pediatric radiology pertained to missed congenital and developmental anomalies (average $1,222,932) such as developmental dysplasia of the hip and congenital central nervous system anomalies. More than half of pediatric radiology claims arose in the ambulatory setting. Pediatric radiology is not immune from claims of medical malpractice and these claims result in high monetary payouts, particularly for missed diagnoses of congenital and developmental anomalies. Our data suggest that efforts to reduce diagnostic error in the outpatient radiology setting, in the interpretation of radiographs, and in the improved diagnosis of fractures and congenital and developmental anomalies would be of particular benefit to the pediatric radiology community.

Hypohidrotic ectodermal dysplasia (HED) is a rare congenital disorder arising from deficient development of ectoderm-derived structures including skin, nails, glands and teeth. The phenotype of HED is associated with mutation in EDA, EDAR, EDARADD and NEMO genes, all of them disruptingNF-κB signaling cascade necessary for initiation, formation and differentiation in the embryo and adult. Here we describe a novel acceptor splice site mutation c.730-2 A>G(IVS 8-2 A>G) in EDAR gene in homozygous form in all affected members of a family,and in heterozygous form in carriers. Bioinformatics analysis showed that this mutation can create a new broken splicing site and lead to aberrant splicing.

Background The 2020 Sustainable Development goals call for 100% certified interruption or control of the three main forms of Chagas disease transmission in Latin America. However, how much will achieving these goals to varying degrees control Chagas disease; what is the potential impact of missing these goals and if they are achieved, what may be left? Methods We developed a compartmental simulation model that represents the triatomine, human host, and non-human host populations and vector-borne, congenital, and transfusional T. cruzi transmission between them in the domestic and peridomestic settings to evaluate the impact of limiting transmission in a 2,000 person virtual village in Yucatan, Mexico. Results Interruption of domestic vectorial transmission had the largest impact on T. cruzi transmission and prevalence in all populations. Most of the gains were achieved within the first few years. Controlling vectorial transmission resulted in a 46.1–83.0% relative reduction in the number of new acute Chagas cases for a 50–100% interruption in domestic vector-host contact. Only controlling congenital transmission led to a 2.4–8.1% (30–100% interruption) relative reduction in the total number of new acute cases and reducing only transfusional transmission led to a 0.1–0.3% (30–100% reduction). Stopping all three forms of transmission resulted in 0.5 total transmission events over five years (compared to 5.0 with no interruption); interrupting all forms by 30% resulted in 3.4 events over five years per 2,000 persons. Conclusions While reducing domestic vectorial, congenital, and transfusional transmission can successfully reduce transmission to humans (up to 82% in one year), achieving the 2020 goals would still result in 0.5 new acute cases per 2,000 over five years. Even if the goals are missed, major gains can be achieved within the first few years. Interrupting transmission should be combined with other efforts such as a vaccine or improved access to care, especially for the population of already infected individuals. PMID:29554086

Child, neglect and oral health

PubMed Central

2013-01-01

Background Despite advancements in oral health policies, dental caries still a problem. The lack of parents/caregiver’s care regarding child’s oral health, which characterizes neglect, may lead to a high prevalence of caries. Therefore, the objective of this study was to analyze the relation between dental caries and neglect in five year-old children. Methods Quantitative study performed in two different moments. First, the children underwent oral examinations and physical inspection. Then, a semi-structured interview was performed with parents of children with high and low caries rate. Results In all, 149 physical inspections and oral exams were performed. The number of decayed, missing and filled teeth – dmf-t was 2.75 (SD 2.83); 16 children had extremely high values (dmf-t ≥7), 85 intermediate values (1 ≤ dmf-t ≥ 6) and 48 extremely low (dmf-t = 0). Nearly all caregivers were female (96.7%; n = 29), mostly mothers (93.3%; n = 28). Associations were found between caries experience and reason of the last consultation (p = 0.011), decayed teeth and child’s oral health perception (p = 0.001). There was a trend towards a significant association between general health and decayed teeth (p = 0.079), general hygiene and caries experience (p = 0.083), and caries experience and number of times the child brushes the teeth (p = 0.086). Conclusion There’s a relation between caries experience and children’s oral health perception by caregivers, as well as between caries experience and children’s access to dental care. There is a trend towards association between caries experience and risk factors suggestive of neglect. PMID:24238222

The aim of this study was to analyze the associations between missing teeth, occlusal support, and temporomandibular disorders (TMD) among elderly Vietnamese. The study consisted of 145 TMD and 112 non-TMD (control group) participants aged 65 to 74 years. TMD was evaluated using Diagnostic Criteria for Temporomandibular Disorders (DC/TMD) Axis I. An occlusal unit (OU) was defined as the cusp of a tooth coupled with the fossa of its antagonist tooth. A premolar pair was counted as one OU and a molar pair as two OUs. Dentition was divided into four occlusal support zones (OSZs) based on occluding pairs of posterior teeth by using Eichner classification: Class A had 4 OSZs, Class B had 1 to 3 OSZs or only anterior teeth, and Class C had no OSZ. The TMD group lost significantly more posterior teeth (mean ± SD 5.1 ± 4.7) than the control group (4.0 ± 3.9, P = .033). The mean ± SD OUs of the TMD and control groups were 5.1 ± 4.6 and 6.0 ± 4.3, respectively, which was nonsignificant (NS). The distribution of Class A (40.7%), Class B (40.0%), and Class C (19.3%) among the TMD group was not significantly different from the control group (50.0%, 38.4%, and 11.6%, respectively, NS). The odds of having TMD were positively associated with total unilateral loss of OUs (OR = 3.4, 95% CI = 1.2-9.4, P = .020) and total bilateral loss of OUs (OR = 2.7, 95% CI = 1.2-6.6, P = .027). Total loss of OSZs on one or both sides of the mouth were found to be predictors of TMD among elderly Vietnamese.

The objectives of this study are to determine the effect of fluoride exposure on permanent tooth eruption patterns as well as to understand its effect on caries attack rate by accounting for the number of erupted tooth surfaces. We analyzed data from the 1986-1987 National Survey of Oral Health of US Schoolchildren to determine the mean number of erupted permanent teeth and permanent first molars according to fluoride level in drinking water. The analysis included 13,348 children aged 5-17 years with a history of single residence. We also estimated the attack rate (decayed, missing, and filled surfaces/surfaces at risk) for fluoride deficient, suboptimal, and optimally fluoridated areas adjusting for covariates. Multivariable statistical analyses were performed to control for potential confounders. By age 7, almost all permanent first molars had erupted. The adjusted mean number of erupted permanent first molars per child were 3.81, 3.67, and 3.92 in areas with <0.3, 0.3-<0.7, and 0.7-1.2 ppm of fluoride, respectively. The adjusted caries attack rate in the first permanent molars among 5- to 17-year-old children was 93, 81, and 78 per 1,000 surfaces in fluoride deficient, suboptimal, and optimally fluoridated areas, respectively (P < 0.0001). This pattern of higher first molar attack rate among children in the fluoride-deficient communities was also observed in all erupted teeth. Exposure to fluoride in drinking water did not delay the eruption of permanent teeth. The observed difference in dental caries experience among children exposed to different fluoride levels could not be explained by the timing of eruption of permanent teeth. © 2014 American Association of Public Health Dentistry.

This study aims to evaluate the impact of untreated dental caries and its clinical consequences on the quality of life of Brazilian schoolchildren aged 8-10 years. A randomly selected sample of 587 children underwent a clinical oral examination for the assessment of untreated dental caries and clinical consequences. The WHO criteria (decayed component of the decayed, missing, and filled teeth--D-DMFT in permanent teeth or d-dfmt in primary teeth) and the PUFA index, which records the presence of severely decayed permanent (upper case) and primary (lower case) teeth with visible pulpal involvement (P/p), as well as ulceration caused by dislocated tooth fragments (U/u), fistula (F/f), and abscesses (A/a), were used for the oral examination. Oral health-related quality of life (OHRQoL) was evaluated using the Child's Perception Questionnaire (CPQ8-10). Poisson regression was employed to test unadjusted and adjusted associations between untreated dental caries/clinical consequences and OHRQoL. The prevalence of untreated dental caries was 64.6% (D/d component of DMFT/dmft > 0) and 17.9% of children exhibited clinical consequences of caries (PUFA/pufa index >0). In the adjusted models, untreated caries was significantly associated with the total CPQ8-10 score and all subscale scores. The clinical consequences of dental caries (PUFA/pufa index >0) were significantly associated with the total CPQ8-10 as well as the oral symptoms and functional limitations' subscales. Untreated dental caries and its clinical consequences exerted a negative impact on the OHRQoL of the schoolchildren analyzed.

During archaeological excavation, carried out in the S. Francesco Monastery at Lucca (Tuscany, Italy), a golden dental appliance was discovered. The prosthesis was found, together with commingled human remains, in the collective tomb of the aristocratic family of the Guinigi, a powerful family who governed Lucca from 1392 until 1429. The exact archaeological dating of the prosthesis was not possible, but some elements suggest a dating to the beginning of the 17th century. Aim of the paper is to study and describe the dental appliance trough a multidisciplinary approach. Macroscopical and micro-CT examinations were performed to investigate the technics used for the realization of the dental prosthesis. SEM analysis was performed to study alloy composition of the metallic fixing lamina and microstructure of the deposits on the dental surface. The dental prosthesis consists in five mandibular teeth: three central incisors and two lateral canines linked together by a golden band inserted into the dental roots to replace the anterior arch of the jaw. Micro-CT scan revealed the presence of two small golden pins inserted into each tooth crossing the root and fixing the teeth to the internal gold band. SEM examination of the lamina indicated a homogeneous composition, with average contents of 73 wt% gold, 15.6 wt% Ag, and 11.4 wt% Cu. Apposition of dental calculus on the teeth indicated that the prosthesis had been worn for a long period. This dental prosthesis provides a unique finding of technologically advanced dentistry in this period. In fact, during the Early Modern Age, some authors described gold band technology for the replacement of missing teeth; nevertheless, no direct evidences of these devices have been brought to light up so far. © 2016 Wiley Periodicals, Inc.

Short stature Revealing a Pycnodysostosis: A Case Report

PubMed Central

Aynaou, Hayat; Skiker, Imane; Latrech, Hanane

2016-01-01

Introduction: Pycnodysostosis is a rare genetic disease characterized by osteosclerosis and bone fragility. The clinical aspects are varied including short stature, acro-osteolysis of distal phalanges, and dysplasia of the clavicles. Oral and maxillofacial manifestations of this disease are very clear. The head is usually large, a beaked nose, obtuse mandibular angle, and both maxilla and mandible are hypoplastic. Dental abnormalities are common. We report a case with the typical clinical and radiological characteristics of the Pycnodysostosis associated with a conductive hearing loss, an association rarely reported. Case Presentation: A 12-year-female was admitted in our institute for short stature with a dysmorphic facies for evaluation. The patient reported a history of multiple fractures of the long bones after a trivial fall. On physical examination, she had the following features: short stature, limited mouth opening, short hands and feet with dysplastic nails; frontal and occipital bossing; and hypoplasia of the maxilla and mandible. Examination of the mouth: grooved palate, caries of the teeth, impacted and malposed teeth, persistent deciduous teeth and missing teeth. Laboratory investigations were normal. The radiographic examination showed a generalized increase in the bone density, slight condensation of the skull base and a very open mandibular angle. X-rays showed tapered phalanges with acro-osteolysis of the distal phalanges. A symptomatic treatment was proposed based on fracture prevention, oral hygiene, frequent dental visits and psychiatric support. Conclusion: The clinical and radiological features are the bases for the diagnosis of this disease. It is important to make the diagnosis as early as possible in order to plan the treatment and to provide a better life quality to the patients. PMID:27703936

The characterization of unidentified bodies or suspected human remains is a frequent and important task for forensic investigators. However, any identification method requires clues to the person’s identity to allow for comparisons with missing persons. If such clues are lacking, information about the year of birth, sex and geographic origin of the victim, is particularly helpful to aid in the identification casework and limit the search for possible matches. We present here results of stable isotope analysis of 13C and 18O, and bomb-pulse 14C analyses that can help in the casework. The 14C analysis of enamel provided information of the year of birth with an average absolute error of 1.8±1.3 years. We also found that analysis of enamel and root from the same tooth can be used to determine if the 14C values match the rising or falling part of the bomb-curve. Enamel laydown times can be used to estimate the date of birth of individuals, but here we show that this detour is unnecessary when using a large set of crude 14C data of tooth enamel as a reference. The levels of 13C in tooth enamel were higher in North America than in teeth from Europe and Asia, and Mexican teeth showed even higher levels than those from USA. DNA analysis was performed on 28 teeth, and provided individual-specific profiles in most cases and sex determination in all cases. In conclusion, these analyses can dramatically limit the number of possible matches and hence facilitate person identification work. PMID:23922751

Antibody response to actinomyces antigen and dental caries experience: implications for caries susceptibility.

Fluoridated dentifrices reduce dental caries in subjects who perform effective oral hygiene. Actinomyces naeslundii increases in teeth-adherent microbial biofilms (plaques) in these subjects, and a well-characterized serum immunoglobulin G (IgG) antibody response (Actinomyces antibody [A-Ab]) is also increased. Other studies suggest that a serum IgG antibody response to streptococcal d-alanyl poly(glycerophosphate) (S-Ab) may indicate caries experience associated strongly with gingival health and exposure to fluoridated water. The aim of this study was to investigate relationships between A-Ab response, oral hygiene, S-Ab response, and caries experience. Measurements were made of A-Ab and S-Ab concentrations, caries experience (number of decayed, missing, and filled teeth [DMFT], number of teeth surfaces [DMFS], and number of decayed teeth needing treated [DT]), exposure to fluoridated water (Flu), mean clinical pocket depth (PD; in millimeters), and extent of plaque (PL) and gingival bleeding on probing (BOP). A-Ab concentration, the dependent variable in a multiple regression analysis, increased with S-Ab concentration and decreased with PL and DMFT adjusted for Flu (R(2) = 0.51, P < 0.002). Residual associations with age, DMFS, DT, and BOP were not significant. In addition, an elevated A-Ab response, defined from immunoprecipitation and immunoassay measurements, indicated a significant, 30% reduction in DMFT after adjustment for significant age and Flu covariance (analysis of variance with covariance F statistic = 10.6, P < 0.003; S-Ab response and interactions not significant). Thus, an elevated A-Ab response indicates less caries in subjects performing effective oral hygiene using fluoridated dentifrices. Conversely, a low A-Ab response is suggestive of decreased A. naeslundii binding to saliva-coated apatite and greater caries experience, as reported by others.

An epidemiology analysis was performed to identify patient and dentist factors influencing over- and undertreatment of restorative services in a sample of insured adults. At baseline, 681 Washington State employees and their spouses, aged 20 to 34 years and residing in the Olympia or Pullman areas, were interviewed by telephone. Oral assessments were conducted to measure personal characteristics, oral disease, and restoration quality. Adults were followed for two years to measure use of restorative services from dental insurance claims. Each adult's baseline and claims data were linked with provider and practice variables collected from the dentist who provided treatment. For overtreatment, 39 percent of adults received one or more replacement restorations in nondecayed teeth with satisfactory fillings at baseline, while 18 percent of adults had one or more restorations placed in teeth with no decay and fillings. An adult's probability of overtreatment was higher if the adult had more fillings at baseline, or if an adult's dentist was younger, had a busy practice, advertised, charged higher fees, had less continuing education, or had a solo practice. For undertreatment, about 16 percent of adults either received no replacement restorations in teeth with unsatisfactory fillings at baseline, or had decayed teeth at baseline that were not filled or crowned. An adult's probability of undertreatment was higher if an adult had less decayed or more missing surfaces at baseline, or if an adult's dentist believed in sharing information with patients, had a busy practice, or reported not placing fillings when radiographic evidence of new caries was present. A minority of adults aged 20 to 34 experienced potential over- or undertreatment of restorative services, which are influenced by both patient and dentist factors.

The relationship between type 2 diabetes oral physiology, nutritional intake and quality of life has not been fully elucidated. We assessed the impact of type 2 diabetes - exclusive or associated with hypertension with beta-blockers treatment - on oral physiology, mastication, nutrition and quality of life. This cross-sectional study was performed with 78 complete dentate subjects (15 natural teeth and six masticatory units minimum; without removable or fixed prostheses), divided into three groups: diabetics (DM) (n = 20; 45·4 ± 9·5 years), diabetics with hypertension and receiving beta-blockers treatment (DMH) (n = 19; 41·1 ± 5·1 years) and controls (n = 39; 44·5 ± 11·7 years) matched for gender, age and socioeconomic status. Blood glucose, masticatory performance, swallowing threshold, taste, food intake, stimulated and unstimulated salivary flow, pH and buffering capacity of saliva were assessed. Glycemia was higher in DM than in controls (P < 0·01). No differences were observed between DM and controls for nutrition and quality of life. Both stimulated and unstimulated salivary flow rate were lower in DMH (P < 0·01), which also presented the lowest number of teeth and masticatory units (P < 0·0001), and reduction in the number of chewing cycles (P < 0·01). Controls showed lower Decayed Missing Filled Teeth index (DMFT) scores in comparison with DMH (P = 0·021). Masticatory performance and saliva buffering capacity were similar among groups. Exclusive type 2 diabetes did not alter oral physiology, nutrition or quality of life. However, when hypertension and beta-blockers treatment were associated with diabetes, the salivary flow rate, chewing cycles and number of teeth decreased. © 2016 John Wiley & Sons Ltd.

Orthodontic space closure is a treatment alternative when a maxillary central incisor is missing. The objective of this report was to present an unusual treatment in which a right maxillary central incisor was moved through the midpalatal suture to replace the absent contralateral tooth. The biologic aspects and clinical appearance of the recontoured lateral and central incisors were analyzed. The position of the examined teeth and the appearance of the surrounding soft tissues were satisfactory; however, the upper midline frenulum deviated to the left. The incisor was successfully moved with no obvious detrimental effects as observed on the final radiographs. In the radiographic and tomographic examinations, the midline suture seemed to have followed the tooth movement. The patient expressed satisfaction with the results. It was concluded that orthodontic movement of the central incisor to replace a missing contralateral tooth is a valid treatment option, and the achievement of an esthetic result requires an interdisciplinary approach, including restorative dentistry and periodontics.

The fetal anomaly ultrasound only detects 65 to 81 % of the patients with congenital heart disease, making it the most common structural fetal anomaly of which a significant part is missed during prenatal life. Therefore, we need a reliable non-invasive diagnostic method which improves the predictive value for congenital heart diseases early in pregnancy. Fetal electrocardiography could be this desired diagnostic method. There are multiple technical challenges to overcome in the conduction of the fetal electrocardiogram. In addition, interpretation is difficult due to the organisation of the fetal circulation in utero. We want to establish the normal ranges and values of the fetal electrocardiogram parameters in healthy fetuses of 18 to 24 weeks of gestation. Women with an uneventful singleton pregnancy between 18 and 24 weeks of gestation are asked to participate in this prospective cohort study. A certified and experienced sonographist performs the fetal anomaly scan. Subsequently, a fetal electrocardiogram recording is performed using dedicated signal processing methods. Measurements are performed at two institutes. We will include 300 participants to determine the normal values and 95 % confidence intervals of the fetal electrocardiogram parameters in a healthy fetus. We will evaluate the fetal heart rate, segment intervals, normalised amplitude and the fetal heart axis. Three months postpartum, we will evaluate if a newborn is healthy through a questionnaire. Fetal electrocardiography could be a promising tool in the screening program for congenital heart diseases. The electrocardiogram is a depiction of the intimate relationship between the cardiac nerve conduction pathways and the structural morphology of the fetal heart, and therefore particularly suitable for the detection of secondary effects due to a congenital heart disease (hypotrophy, hypertrophy and conduction interruption).

Immediate implant restoration of single implants may demonstrate a positive effect on peri-implant soft tissue. Placement of a provisional restoration following implant surgery can create soft tissue contours that resemble normal gingival topography before placement of the definitive prosthesis. This article describes a staged approach of the mandibular permanent right central incisor, which was congenital missing. The proper space for restoration of the missing incisor was created through orthodontic treatment. The scheduled implant site was reconstructed using autogenous bone harvested from the chin region. After a healing period of four months, an implant was installed with the connection of a fixed provisional crown to a prefabricated temporary abutment. The soft tissue around the implant healed according to the contours of the provisional restoration and the emergence profile was used to duplicate the definitive restoration. Peri-implant esthetics was achieved through the staged approach and immediate restoration of the implant. Copyright © 2011. Published by Elsevier B.V.

The aim of the present study was to analyze geriatric oral health predicaments in India. Specifically, to assess the oral health status and treatment needs among the geriatric population attending health camps in New Delhi, Northern India. The sample size for the cross-sectional study comprised of 248 elderly participants aged 60 years having attended the health check-up camps organized in New Delhi, India. The community periodontal index was used for assessment of periodontal disease. The World Health Organization's criterion was used for detection of dentition status and treatment needs. The χ(2) -test was used to compare between categorical variables. The Mann-Whitney U-test was used to compare between two groups for quantitative variables. Regression analysis was carried out to identify the factors associated with dental caries and periodontal disease status. The mean number of affected sextants with the highest community periodontal index score of 4 was 3.54 ± 2.45. Mean decayed, missing and filled teeth score of 16.39 ± 8.97 was recorded among the elderly. Prosthetic need was noted among 206 (83.1%) participants. Age and literacy status contributed to 27% and 12% of the variance respectively in the decayed, missing and filled teeth model. (P < 0.001) Major contributory factors in the periodontal disease model for the 37%, 11% and 11% variance were age, sex and tobacco consumption (P < 0.001). Two striking features of the study were the high levels of unmet prosthetic needs and the extremely low utilization of dental care. There is an urgent necessity to resolve the high burden of unmet prosthetic need among the aged in India. © 2015 Japan Geriatrics Society.

Surveying oral health at the community level should be done at regular intervals. Dental health personnel must assess the oral health status and needs of the community through the collection and interpretation of reliable health information. Thus, the aims of this study were (1) to develop a mobile application for oral health surveys, (2) to analyze the oral status of school children in Bangkok using the newly developed application, and (3) to evaluate user satisfaction with using the Oral Health Survey Mobile Application (OHSMA). The OHSMA Android app was created to facilitate the collection and transfer of oral health status data. The survey data on the oral health status of Grades 1-6 Thai schoolchildren were collected and analyzed using the OHSMA. A 5-point Likert scale questionnaire was used to evaluate the satisfaction of 125 dental students when using this new application compared with using paper forms. The prevalence of dental caries in 441 schoolchildren was 79.7%. The total mean decayed, missing, and filled for primary teeth (dmft) and decayed, missing, and filled for permanent teeth (DMFT) were 4.09 (d + D = 3.29, m + M = 0.15, and f + F = 0.65). Users indicated high satisfaction scores for three OHSMA features: font, color, and proper size. The results showed that paper forms were easier for inputting and recording the data compared with the OHSMA. However, the OHSMA was significantly easier for searching data and reporting data compared with paper forms (OHSMA 3.80, paper forms 3.35; p < 0.001, and OHSMA 3.80, paper forms 3.51; p < 0.001), respectively. Despite some limitations, this study suggests that the mobile application has the potential to collect valuable oral health survey data.

There is evidence of an association between social determinants and child health. To identify sociodemographic characteristics related to child health inequalities and to analize the cumulative effect on health of risk factors based on these characteristics. We evaluated 4-13 year-old children in Bariloche between June 2008 and May 2009. The following sociodemographic characteristics were taken into account: socioeconomic level, maternal education, adolescent pregnancy, medical coverage, unsafeness, and family habits. We assessed parental perception of physical, and social and emotional health, nutritional status and oral health in relation to these characteristics and the accumulation of risk factors. We used survey, anthropometry and oral examination. One hundred and eighty students participated. The level of maternal education was associated with the child's physical, social and emotional, and oral health. The percentage of children with missing teeth or cavities reached 77% among those whose mothers had, at most, completed primary school, compared to 13% among those whose mothers had completed tertiary school or university. The possibility of perceiving a non-optimal physical, and social and emotional health increased 1.8 and 1.4 times with each risk factor, respectively, and the possibility of having missing teeth or cavities was twice as much with each additional risk factor. Overweight and obesity was observed in 27.3% and 8.7% of students, respectively, and no relationship was found with sociodemographic characteristics. A low family socioeconomic level and a low maternal education level were associated with a higher prevalence of unfavorable health outcomes. Multiple risk factors have an cumulative effect on parental perception of physical, social and emotional, and oral health.

This study evaluated the relationships between oral conditions and oral health-related quality of life (OHRQoL), as well as related factors. A crosssectional study was performed on 119 postnatal women who had sought prenatal care during pregnancy in the public health system of São Paulo State, Brazil. The women received oral clinical exams and were interviewed using the questions on the OHIP14. A second survey with information about their socioeconomic status, pregnancy and health habits was administered. The highest OHIP14 scores were found in the area of physical pain, with an average score of 10.6. Average DMFT rate for the population was 12.2 (±6.1), with the majority having DMFT ≥4.5 (89.9%). Most of the women needed some type of dental prosthesis (59.7%), had some type of periodontal disease (90.8%), tooth decay (73.9%), missing teeth (64.7%) and were in need of oral treatment (68.1%). The OHIP14 scores were significantly associated with age (p=0.02), first pregnancy (p<0.001), need for dental prosthesis (p<0.001), presence of dental caries (p<0.001) and missing teeth (p=0.01). In the multivariate analysis, the worst OHRQoL was significantly associated with the presence of caries (p=0.03). The results suggest an association between the worst oral condition and poorer quality of life during pregnancy. This risk group should be prioritized in the health services in order to treat and recover the oral health of pregnant women, promoting better oral health conditions and better quality of life for their children.

To report the outcome of mandibular body fractures treated with a wire-reinforced interdental composite splint (WRICS) in small breed dogs. Retrospective case series. Client-owned small breed dogs (n = 24). Medical records (1998-2012) of small breed dogs (<10 kg) with mandibular body fractures treated by WRICS were reviewed for signalment, history, type of fracture, treatment, and clinical and radiological follow-up. The angle of the fracture line (ANG) was measured on dental radiographs. A mandibular injury severity score (MISS) and a dental injury score (DIS) were evaluated as potential prognostic factors. Fractures most commonly involved P4-M1 (56%), and healed in a mean time of 2.37 ± 0.7 months. Healing was slower (P = .012) if teeth were present in the fracture line and required extraction, hemisection, or root canal therapy prior to WRICS placement (2.39 ± 0.7 months) than if no dental treatment was required (1.46 ± 0.8 months). Contrary to the MISS, the DIS was associated with longer time to bone healing (P = .001; r = .63) and risk of complications (P = .004). Bone healing time was decreased (P = .003; r = .61) with increasing fracture angles. WRICS can be considered to treat mandibular body fractures in small breed dogs if the fracture is not severely comminuted, and if at least the canine and first molar tooth can be used for anchorage. More severe lesions, such as those with teeth in the fracture line and a shorter fracture surface, are associated with prolonged bone healing. © 2017 The American College of Veterinary Surgeons.

To ensure the oral health of a population, clinicians must deliver appropriate dental services, and local communities need to have access to dental care facilities. However, establishment of this infrastructure must be based on reliable information regarding disease prevalence and severity in the target population. The aims of this study were to measure the incidence of dental caries in school children aged 12-14 throughout Qatar, including the influence of socio-demographic factors. A cross-sectional study was conducted in Qatar from October 2011 to March 2012. A total of 2113 children aged 12-14 were randomly selected from 16 schools located in different geographic areas. Three calibrated examiners using World Health Organization (WHO) criteria to diagnose dental caries performed the clinical examinations. Data analyses were subsequently conducted. The mean decayed, missing, and filled teeth index values were respectively 4.62 (±3.2), 4.79 (±3.5), and 5.5 (±3.7), for 12, 13, and 14 year-old subjects. Caries prevalence was 85%. The mandibular incisors and canines were least affected by dental caries, while maxillary and mandibular molars exhibited the highest incidence of dental caries. Dental caries were affected by socio-demographic factors; significant differences were detected between female and male children, where more female children showed dental caries than male children. In addition, children residing in semi-urban areas showed more dental caries than in urban areas. Results indicated that dental caries prevalence among school children in Qatar has reached critical levels, and is influenced by socio-demographic factors. The mean decayed, missing, and filled teeth values obtained in this study were the second highest detected in the Eastern Mediterranean region.

The aim of this study was to analyze the influence of socio-behavioral variables on the prevalence and severity of dental caries in 4- to 6-year-old children. A cross-sectional study was performed on a sample of 1993 children enrolled in 58 public preschools from Araçatuba City, São Paulo State, Brazil, during 2010. The exams were made using the decayed, missing, and filled teeth index (World Health Organization methodology) and detection criteria for non-cavitated lesions. A tested, self-administered questionnaire was sent to parents to obtain information about their socio-behavioral characteristics. Standardization was performed to verify concordance among examiners (kappa = 0.84). The prevalence of cavitated caries lesions was 41.2% (821), and the prevalence of both, cavitated and non-cavitated caries lesions, was 43.9% (875). The means ± standard deviations of the decayed, missing, and filled teeth index for children aged 4, 5, and 6 years were 1.18 ± 2.45, 1.65 ± 2.67, and 1.73 ± 2.77, respectively. Caries were significantly more prevalent in children from families with low incomes and low educational levels. The presence of dental caries was associated with access to dental services (p < 0.05). The associations between both, cavitated and non-cavitated dental caries lesions, and the frequency of oral hygiene were statistically significant. The prevalence of dental caries in preschoolers was strongly associated with factors related to the children's parents. Therefore, information about parents' socio-economic status, behaviors, and attitudes in relation to oral health should be considered when planning prevention and educational programs for the oral health of preschool children.

Background Inequalities in the utilisation of dental services in Brazil are remarkable. The aim of this study was to evaluate the association of contextual and individual factors with the utilisation of dental services by Brazilian adults using the Andersen’s behavioural model. Methods Individual-level data from 27,017 adults residents in the State capitals who were interviewed in the 2013 Brazilian National Health Survey were pooled with contextual city-level data. The outcomes were non-utilisation of dental services and last dental visit over 12 months ago. Individual predisposing variables were age, sex, race/skin colour, schooling and social network. Individual enabling variables included income, health insurance and registration in primary health care. Individual need variables were self-perceived dental health and self-reported missing teeth. Multilevel logistic regression models were performed to estimate odds ratio (OR) and 95% confidence intervals (95% CIs) of the association of contextual and individual predisposing, enabling and need-related variables with dental services outcomes. Results Predisposing (OR = 0.89; 95% CI 0.81–0.97) and enabling (OR = 0.90; 95% CI 0.85–0.96) contextual factors were associated with non-utilisation of dental services. Individual predisposing (sex, race/skin colour, schooling), enabling (income, health insurance) and need (self-perceived oral health, missing teeth) were associated with non-utilisation of dental services and last dental visit over 12 months ago. The latter was also associated with other individual predisposing (age, social network) and need (eating difficulties due to oral problems) characteristics. Conclusions Individual and contextual determinants influenced dental services utilisation in Brazilian adults. These factors should be on the policy agenda and considered in the organisation of health services aiming to reduce oral health inequalities related to access and utilisation of dental services.

We examined the association between utilization of care for a dental problem (utilization-DP) and parent-reported dental problem (DP) urgency among children with DP by type of health care insurance coverage. We used weighted 2008 National Health Interview Survey data from 2,834 children, aged 2-17 years with at least one DP within the 6 months preceding survey. Explanatory variables were selected based on Andersen's model of healthcare utilization. Need was considered urgent if DP included toothache, bleeding gums, broken or missing teeth, broken or missing filling, or decayed teeth and otherwise as non-urgent. The primary enabling variable, insurance, had four categories: none, private health no dental coverage (PHND), private health and dental (PHD), or Medicaid/State Children's Health Insurance Program (SCHIP). Predisposing variables included sociodemographic characteristics. We used bivariate and multivariate analyses to identify explanatory variables' association with utilization-DP. Using logistic regression, we obtained adjusted estimates of utilization-DP by urgency for each insurance category. In bivariate analyses, utilization-DP was associated with both insurance and urgency. In multivariate analyses, the difference in percent utilizing care for an urgent versus non-urgent DP among children covered by Medicaid/SCHIP was 32 percentage points; PHD, 25 percentage points; PHND, 12 percentage points; and no insurance, 14 percentage points. The difference in utilization by DP urgency was higher for children with Medicaid/SCHIP compared with either PHND or uninsured children. Expansion of Medicaid/SCHIP may permit children to receive care for urgent DPs who otherwise may not, due to lack of dental insurance. © 2016 American Association of Public Health Dentistry.

Quarter of a century of change: caries experience in Australian children, 1977-2002.

The establishment of the evaluation programme of the Australian School Dental Scheme has led to continuous surveillance of child oral health extending from 1977 to the present day. The aims of this study were to examine the state of child oral health in Australia in 2002 and to explore longer term trends across the quarter of a century of recorded surveillance activity. Caries data were obtained for children who were enrolled in the School Dental Services of each state and territory for the years 1977-2002. Data collection derived from routine examinations within the School Dental Service with oral examinations carried out by dentists and dental therapists. There were considerable declines in caries experience between 1977 and the mid to late 1990s, with mean decayed, missing and filled deciduous teeth (dmft) for 6-year-old children decreasing from over 3 in 1977 to approximately 1.6 in 1996, and permanent 12-year-old decayed, missing and filled teeth (DMFT) decreasing from 4.8 in 1977 to 0.89 in 1998. However, since the mid to late 1990s, deciduous 6-year-old dmft has increased by 24 per cent and 12-year-old DMFT has increased by almost 15 per cent. Reductions in caries experience of those children with the most disease have also ceased, and between 1999 and 2002 an increase in the Significant Caries Index occurred. Improvements in the oral health of Australian children halted during the mid 1990s, after which caries experience has increased. It is important that we understand the changes taking place and their causes, so that action can be taken to halt any further possible declines in child oral health.

ABSTRACT Objective: To compare a limited array of chewing-stimulated saliva features (salivary flow, pH and buffer capacity) in a sample of elderly Mexicans with clinical, sociodemographic and socio-economic variables. Subjects and Methods: A cross-sectional study was carried out in 139 adults, 60 years old and older, from two retirement homes and a senior day care centre in the city of Pachuca, Mexico. Socio-demographic, socio-economic and behavioural variables were collected through a questionnaire. A trained and standardized examiner obtained the oral clinical variables. Chewing-stimulated saliva (paraffin method) was collected and the salivary flow rate, pH and buffer capacity were measured. The analysis was performed using non-parametric tests in Stata 9.0. Results: Mean age was 79.1 ± 9.8 years. Most of the subjects included were women (69.1%). Mean chewing-stimulated salivary flow was 0.75 ± 0.80 mL/minute, and the pH and buffer capacity were 7.88 ± 0.83 and 4.20 ± 1.24, respectively. Mean chewing-stimulated salivary flow varied (p < 0.05) across type of retirement home, tooth brushing frequency, number of missing teeth and use of dental prostheses. pH varied across the type of retirement home (p < 0.05) and marginally by age (p = 0.087); buffer capacity (p < 0.05) varied across type of retirement home, tobacco consumption and the number of missing teeth. Conclusions: These exploratory data add to the body of knowledge with regard to chewing-stimulated salivary features (salivary flow rate, pH and buffer capacity) and outline the variability of those features across selected sociodemographic, socio-economic and behavioural variables in a group of Mexican elders.

To evaluate longitudinally ART sealants placed in Chinese school children under field conditions. 191 ART sealants were placed in 140 children, aged 11-14 years, by five assistant dentists in four secondary schools in Deyang, Sichuan Province, China. Teeth selected for sealing were those with pits and fissures that were deep or showing early enamel caries. Teeth were excluded if there was obvious cavitation extending into dentine. Standard instruments and procedures for ART sealants were used. The material used was a high-viscosity glass-ionomer (Ketac-Molar, 3MESPE) that was inserted into the pits and fissures with the "press-finger" technique. The status of the sealants was evaluated annually over 6 years after placement by the same examiner who was not involved in the placement of the sealants using explorers, mouth-mirrors and an intra-oral fibre-optic light. No missing sealants were replaced during the study. 107 sealants (56% of the original) were examined after 6 years. The cumulative survival rates of the sealants (partially or fully retained) after 2, 4 and 6 years were 79%, 68% and 59%, respectively. Caries prevention lagged the fall in sealant survival but remained high throughout the study period, being over 90% in the first 4 years and 85% after 6 years. ART sealants placed under field conditions in Chinese schoolchildren have a high retention rate. Missing sealants should be replaced to maintain their preventive efficacy. The sealing of pits and fissures can be an effective caries preventive approach. Resin-based sealants have the disadvantage in that they require an optimal level of moisture control during placement. In children and in outreach situations glass ionomer ART sealants, which are more moisture tolerant, can offer a viable alternative. Copyright © 2013 Elsevier Ltd. All rights reserved.

Social inequalities in oral health and in use of oral health care services among adolescents in Uganda.

2004-09-01

The aim of this study was to describe clinical and self-perceived indicators of oral health status and the use of oral health care services by social and demographic characteristics. In 2001, a cross-sectional random sample survey was conducted in urban and rural settings in Uganda (Kampala and Lira, respectively), and 1146 secondary school students with a mean age of 15.8 years completed questionnaires in school. Dental caries was recorded by one examiner on a random subsample of 372 students. Logistic regression analyses revealed that being an urban resident was associated with higher odds for having dental caries (dmft > 0), seeking care because of toothache (delayed treatment demand) and being dissatisfied with one's own oral health status [adjusted odds ratio (OR) = 1.5-2.1]. Being an urban resident was associated with lower odds for oral health care attendance generally and for having missing teeth in particular (adjusted OR = 0.6-0.4). Students who had parents with a higher education and those with weak social ties were, respectively, less and more likely to be dissatisfied with their oral health status. As compared to caries-free participants, the odds for being dissatisfied with oral health and delayed treatment demand increased significantly with an increasing dmft score (adjusted OR = 2.1-3.2). Urban students were most likely to have a dmft > 0 and to rate their oral health status negatively. Having received dental care and the prevalence of missing teeth, and delayed treatment demand were, respectively, most and least prevalent among rural students. Dental caries at different diagnostic cut-off points and weak social ties affected self-reported oral health negatively, independently of social and demographic characteristics.

This study covers phase IV of a prospective clinical long-term study. Objective of this clinical investigation was to analyze the effects of a long-term prevention program on dental and oral health of teenagers at the age of 13 to 14 years. The entire study was subdivided into four phases. Phase I comprised an individual preventive care during pregnancy ("primary-primary prevention"); phase II assessed mothers and their young children until the age of 3 years ("primary prevention"); and in phase III, mothers and children at the age of 6 years were investigated. In phase IV of the study, the oral health of 13- to 14-year-old teenagers was examined (13.4 +/- 0.5 years; n = 29). All phases consisted of an examination, education about oral health care, and treatment based on the concept of an early oral health care promotion. The control group consisted of randomly selected adolescents at the same age (n = 30). The following clinical parameters were assessed: decayed/missing/filled teeth (DMF-T)/decayed, missing, and filled surface teeth index, hygiene index, papilla bleeding index, Periodontal Screening Index, and Streptococcus mutans/Lactobacillus concentration in saliva. The teenagers of the "prevention" group of phase IV of our prospective study revealed a share of 89.7% caries-free dentitions (65.5% sound; 24.2% caries-free with fillings). Mean DMF-T was 0.55 +/- 1.0. The control group showed a significantly higher mean DMF-T of 1.5 +/- 1.5 (p < 0.05) and revealed 56.7% of caries-free dentitions (30% sound, 26.7% caries-free with restorations). Our data clearly document that an early oral health care promotion starting during pregnancy may cause a sustained and long-term improvement of the oral health of children.

The aim of this retrospective hospital-based study was to elucidate the dentomaxillofacial characteristics of ectodermal dysplasia. Six Japanese individuals (one male and five female; age range, 12.7-27.2 years) underwent comprehensive examinations, including history recording, cephalometric analysis, panoramic radiography, and analysis of dental models. All the subjects had two or more major manifestations for clinical diagnosis of ectodermal dysplasia (e.g., defects of hair, teeth, nails, and sweat glands). They presented hypodontia (mean number of missing teeth, 9.5; range, 5-14), especially in the premolar region, and enamel dysplasia. Five subjects had bilateral molar occlusion, whereas one subject had unilateral molar occlusion. The common skeletal features were small facial height, maxillary hypoplasia, counterclockwise rotation of the mandible, and mandibular protrusion. Interestingly, the maxillary first molars were located in higher positions and the upper anterior facial height was smaller than the Japanese norm. The results suggest that vertical and anteroposterior maxillary growth retardation, rather than lack of occlusal support due to hypodontia, leads to reduced anterior facial height in individuals with ectodermal dysplasia. © 2014 Japanese Teratology Society.

Within the context of preventing non-communicable diseases, the World Health Report (2002) and the WHO Global Oral Health Program (2003) put forward a new strategy of disease prevention and health promotion. Greater emphasis is placed on developing global policies in oral health promotion and oral disease prevention. The Decayed, Missing, Filled Teeth (DMFT) index does not meet new challenges in the field of oral health. Dental erosion seems to be a growing problem, and in some countries, an increase in erosion of teeth is associated with an increase in the consumption of beverages containing acids. Therefore, within a revision of the WHO Oral Health Surveys Basic Methods, new oral disease patterns, e.g. dental erosion, have to be taken into account. Within the last 20 years, many studies on dental erosion have been carried out and published. There has been a rapid growth in the number of indexes quantifying dental erosion process in different age groups. However, these indexes are not comparable. This article discusses quality criteria which an index intended for assessing tooth erosion should possess. PMID:18228060

This paper describes the estimated prevalence of dental caries and periodontal disease in 2,550 children, 5 through 17 years of age, who resided in five southwestern states of the United States and were examined in the Hispanic Health and Nutrition Examination Survey (HHANES) of 1982-84 of the National Center for Health Statistics. Dental caries in the Mexican American children was predominantly a disease of occlusal surfaces of molars; few smooth surfaces of posterior and anterior teeth were affected by caries. This intra-oral distribution of dental caries strongly supports the use of fissure sealants as a preventive procedure. Filled tooth surfaces contributed about 66 per cent of the total DMFS (decayed, missing, filled surfaces) scores. The analysis also shows that about 50 per cent of the 17 year old Mexican Americans had five or more filled or decayed teeth. Mild gingivitis was prevalent (76.9 per cent) in the Mexican American children. PMID:3605476

Orthodontic treatment in cherubism: an overview and a case report.

Cherubism is a rare hereditary disease that frequently manifests as a painless enlargement of the mandible and/or maxilla. The disease usually progresses rapidly during the first and second decades of life but it is self-limiting and often regresses. Although few orthodontic case reports describing cherubic patients exist, the timing and extent of surgical intervention is controversial. This present paper aims to review the treatment literature and provide a case report of a patient who underwent orthodontic/surgical management. The patient presented with severe cherubism in her late teenage years; her main complaint was poor facial and dental appearance. Multiple teeth were missing and those present demonstrated significant preoperative root resorption. Treatment consisted of orthodontic alignment of the upper anterior teeth and a recontouring osteotomy. Confirmed by the patient, the combination approach led to a significant improvement in facial aesthetics and better self-esteem. Tooth movement through the osseous lesions was uneventful and no further root resoption was observed. Orthodontic treatment may be undertaken in those affected by Cherubism even with pre-existing idiopathic root resorption, but patients need to be appropriately informed and consented.

Timor-Leste is one of the poorest countries in the world. The aim of this article was to investigate the association between socioeconomic status (SES) and dental caries experience in children living in Dili. Four out of 6 Dili subdistricts and 40 schools were randomly selected. Equal numbers of school children from 4 age groups (6-8, 9-11, 12-14, 15-17 years) were invited to participate. Data were gathered via a questionnaire and an oral examination by dental practitioners. In bivariate analysis, decayed, missing, and filled teeth index for deciduous + permanent teeth (dmft) was higher in children from mid- to high-SES than low-SES schools (1.1, 2.2, P = .001). With age, having had a toothache and dental visiting in the past 12 months in the multivariable model, higher dmft was found in children from mid- to high- to low-SES schools ( P < .001). The primary dental caries experience was greater among children from mid- to high- than low-SES schools, which may be explained by high sugar consumption.

Cerebral palsy is a non-progressive disorder resulting from central nervous system damage caused by multiple factors. Almost all cerebral palsy patients have a movement disorder that makes dental treatment difficult. Oral hygiene management is difficult and the risks for periodontitis, dental caries and loss of multiple teeth are high. Placement of dental implants for multiple missing teeth in cerebral palsy patients needs multiple rounds of general anesthesia, and the prognosis is poor despite the expense. Therefore, making the decision to perform multiple dental implant treatments on cerebral palsy patients is difficult. A 33-year-old female patient with cerebral palsy and mental retardation was scheduled for multiple implant treatments. She underwent computed tomography (CT) under sedation and the operation of nine dental implants under general anesthesia. Implant-supported fixed prosthesis treatment was completed. During follow-up, she had the anterior incisors extracted and underwent the surgery of 3 additional dental implants, completing the prosthetic treatment. Although oral parafunctions existed due to cerebral palsy, no implant failure was observed 9 years after the first implant surgery.

Snap-On Smile (DenMat) appliances are tooth-borne overdentures used for a variety of temporary esthetic applications. However, their benefit can be limited in patients with high smile lines and altered gingival architecture because the teeth look too large. In this report, the author shows the chairside application of a silicone denture reline material used to recreate gingival anatomy on an overdenture fabricated from crystallized acetyl resin, the material used in a Snap-On Smile appliance. The author shows the gingival application's durability of greater than 2 years in a 78-year-old patient with multiple missing teeth and a severe mandibular ridge deformity. The author tested several commonly available denture reline materials and their bonding agents, which are known to bond to acrylic resin but have not been shown to bond to crystallized acetyl resin. The author observed no candida colonization during the 2-year reporting period. The author presents a simple and durable chairside technique to reproduce gingival tissue esthetically on Snap-On Smile appliances. Copyright © 2017 American Dental Association.

Mendelian disorders of RANKL/OPG/RANK signaling feature the extremes of aberrant osteoclastogenesis and cause either osteopetrosis or rapid turnover skeletal disease. The patients with autosomal dominant accelerated bone remodeling have familial expansile osteolysis, early-onset Paget’s disease of bone, expansile skeletal hyperphosphatasia, or panostotic expansile bone disease due to heterozygous 18-, 27-, 15-, and 12-bp insertional duplications, respectively, within exon 1 of TNFRSF11A that encodes the signal peptide of RANK. Juvenile Paget’s disease (JPD), an autosomal recessive disorder, manifests extremely fast skeletal remodeling, and is usually caused by loss-of-function mutations within TNFRSF11B that encodes OPG. These disorders are ultra-rare. A 13-year-old Bolivian girl was referred at age 3 years. One femur was congenitally short and curved. Then, both bowed. Deafness at age 2 years involved missing ossicles and eroded cochleas. Teeth often had absorbed roots, broke, and were lost. Radiographs had revealed acquired tubular bone widening, cortical thickening, and coarse trabeculation. Biochemical markers indicated rapid skeletal turnover. Histopathology showed accelerated remodeling with abundant osteoclasts. JPD was diagnosed. Immobilization from a femur fracture caused severe hypercalcemia that responded rapidly to pamidronate treatment followed by bone turnover marker and radiographic improvement. No TNFRSF11B mutation was found. Instead, a unique heterozygous 15-bp insertional tandem duplication (87dup15) within exon 1 of TNFRSF11A predicted the same pentapeptide extension of RANK that causes expansile skeletal hyperphosphatasia (84dup15). Single nucleotide polymorphisms in TNFRSF11A and TNFRSF11B possibly impacted her phenotype. Our findings: i) reveal that JPD can be associated with an activating mutation within TNFRSF11A, ii) expand the range and overlap of phenotypes among the mendelian disorders of RANK activation, and iii) call for mutation analysis to improve diagnosis, prognostication, recurrence risk assessment, and perhaps treatment selection among the monogenic disorders of RANKL/OPG/RANK activation.

Case series Patient: — Final Diagnosis: Ellis van Creveld syndrome Symptoms: Conical teeth • polydactyly • short stature Medication: — Clinical Procedure: — Specialty: Pediatrics and Neonatology Objective: Rare disease Background: Ellis-van Creveld syndrome is an autosomal recessive chondro-ectodermal dysplasia characterized by disproportionate short stature, limb shortening, narrow chest, postaxial polydactyly and dysplastic nails and teeth. In addition, 60% of cases present congenital heart defects. Ellis-van Creveld syndrome is predominantly caused by mutations in the EVC or EVC2 (4p16) genes, with only a few cases caused by mutations in WDR35. Case Report: Here, we report on two Mexican families with patients diagnosed with Ellis-van Creveld syndrome. Family 1 includes four patients: three females of 15, 18, and 23 years of age and a 7-year old male. Family 2 has only one affected newborn male. All patients exhibited multiple features including hypodontia, dysplastic teeth, extra frenula, mild short stature, distal limb shortening, postaxial polydactyly of hands and feet, nail dystrophy, and knee joint abnormalities. Only two patients had an atrial septal defect. In all cases, molecular analysis by Sanger sequencing identified the same homozygous mutation in exon 12 of EVC, c.1678G>T, which leads to a premature stop codon. Conclusions: The mutation c.1678G>T has been previously reported in another Mexican patient and it appears to be a recurrent mutation in Mexico which could represent a founder mutation. The large number of patients in this case allows the clinical variability and spectrum of manifestations present in individuals with Ellis-van Creveld syndrome even if they carry the same homozygous mutation in a same family.

Hypohidrotic ectodermal dysplasia (HED) is a rare congenital disorder arising from deficient development of ectoderm-derived structures including skin, nails, glands and teeth. The phenotype of HED is associated with mutation in EDA, EDAR, EDARADD and NEMO genes, all of them disruptingNF-κB signaling cascade necessary for initiation, formation and differentiation in the embryo and adult. Here we describe a novel acceptor splice site mutation c.730-2 A>G(IVS 8-2 A>G) in EDAR gene in homozygous form in all affected members of a family,and in heterozygous form in carriers. Bioinformatics analysis showed that this mutation can create a new broken splicing site and lead to aberrant splicing. PMID:28357203

To identify the possible association between dental caries and body mass index (BMI) and to explore the effect of BMI on tooth eruption in a cohort of elementary schoolchildren. A 4-year longitudinal study was completed. A total of 110 children from a public elementary school, located in a middle-income area of Mexico City, entered the study; of these, 88 completed the 4-year follow-up period. Dental caries assessments were carried out using the WHO criteria for decayed, missing and filled primary and permanent teeth indices (dmft and DMFT, respectively) and surface indices (dmfs and DMFS, respectively). BMI was used to classify the children's obesity status, according to the Centers for Disease Control 2000 reference charts. At 7 years of age, 29.6% of the children were in the overweight or at risk of being overweight categories and, by 11 years of age, this proportion had risen to 45.5%. The mean dmft for children aged 7 years was 2.70 and, for children aged 11 years, the DMFT was 0.54. Children in the higher BMI categories had more erupted teeth than the other children (p < 0.001). A lower dmfs index was detected in the overweight children, compared with children with a lower BMI (p < 0.001). The overweight children had more erupted teeth and a lower caries index. The complex relationships between body composition and oral health should be considered in pediatric patients.

The aim of this study was to investigate the long-term effects of chemotherapy on the dental and gingival health and dental disturbance parameters of children cancer survivors. Thirty-eight children (mean age 12.2 ± 0.5 years) who underwent chemotherapy at 4.29 ± 1.71 years of age formed the study group. Forty age- and gender-matched healthy children with a similar socioeconomic background served as controls. Subjects' caries status (number of decayed, missing, or filled permanent teeth [DMF-T]) was recorded according to World Health Organization criteria. Subjects' periodontal status was recorded according to the community periodontal index system. Radiographic dental examination was used to analyze dental malformations. DMF-T, D-T (number of decayed permanent teeth), and F-T (number of filled permanent teeth) were significantly higher in the study group compared to the controls (4.61 ± 3.71, 3.97 ± 4.45, respectively, and 0.58 ± 0.14 vs. 2.21 ± 1.01, 0.84 ± 1.82, and 1.18 ±1.07, respectively. The most frequent dental disturbances were root malformation (52.6%) and agenesis (47.4%). According to our examination dental status of long-term survivors is worse than in controls. Hence proper oral hygiene for children cancer survivors (CCS) is critical. In order to meet the need for dental care in CCS health authorities are encouraged to revitalize the dental services Long-term follow-up of CCS is necessary to monitor their dental growth and oral health.

Oral health in Down syndrome children has some peculiar aspects that must be considered in the follow-up of these patients. This study focuses on characterizing the environmental and host factors associated with dental caries in Portuguese children with and without Down syndrome. A sibling-matched, population-based, cross-sectional survey was performed. Down syndrome children presented a significantly greater percentage of children without caries, 78% vs. 58% of non-Down syndrome siblings. This difference in the DMFT index (number of decayed, missing and filled teeth) essentially reflects data obtained from treated teeth, for which 91% of children with Down syndrome had never had a tooth treated vs. 67% of siblings. This result was statistically significant, whereas results for decayed and lost teeth did not differ between Down syndrome children and their unaffected siblings. Additionally, in Down syndrome children, a delayed eruption of the second molar occurs. Down syndrome children and their siblings have similar oral hygiene habits, but a higher percentage of Down syndrome children visit a dentist before the age of three years, in comparison to their siblings. Bruxism was also more common in Down syndrome children compared to their siblings. Our results show that Portuguese children with Down syndrome have lower caries rates than children without Down syndrome. This reduced prevalence may be associated with the parents' greater concern about oral health care in Down syndrome children, resulting in their taking them sooner to visit a dentist, as well as to a higher bruxism prevalence and delayed tooth eruption.

Theme: Cardiology Introduction: Measuring quality of life (QoL) in children and adolescents with congenital heart disease (CHD) is of great clinical importance. The aim of the study was: (a) to adapt the PedsQL Cardiac Module for children aged two to 18 years with CHD in a sample of the Greek population; (b) to determine its reliability and validity. Forward and backward translation methodology was used. Parents and children completed the instrument during: (a) hospitalization and (b) visits in the paediatric cardiology outpatient department. Cross-informant variance between children and parents was thoroughly assessed. Missing item responses did not exceed 5%. All internal consistency reliability coefficients for the inventory exceeded the minimum standards for group comparisons, over 0.75. Hypothesized correlations between cardiac module and core scales were statistically significant, (p<0.05). Agreement between children and parents was relatively high. Pilot study results will be additionally presented. The findings support the feasibility, reliability and validity of the Greek translation of the PedsQL Cardiac Module in children with congenital heart defect (CHD).

Studies in recent years have explored lifestyle habits and health-risk behaviours in adult congenital heart disease (ACHD) patients when compared to controls. The aim of this study was to investigate differences in lifestyle habits between Maltese and other European ACHD patients. Data on alcohol consumption, cigarette smoking, substance misuse, dental care and physical activity collected in 2013-2015 during "Assessment of Patterns of Patient-Reported Outcomes in Adults with Congenital Heart disease-International Study" (APPROACH-IS) were analysed. Responses from 119 Maltese participants were compared to those of 1616 participants from Belgium, France, Italy, Norway, Sweden, Switzerland and the Netherlands. Significantly fewer Maltese patients with simple (Maltese 84.1% vs. European 97.5%, p < 0.001) and moderately complex CHD (Maltese 83.6% vs. European 97.4%, p < 0.001) brushed their teeth daily. Only 67.2% of Maltese with moderately complex disease had dental reviews in the previous year compared to 80.3% of Europeans (p = 0.02). Maltese patients with simple (Maltese 31.8% vs. European 56.1%, p = 0.002) and moderately complex lesions (Maltese 30.0% vs. European 59.2%, p < 0.001) performed less regular sport activities. Comparison by country showed Maltese patients to have significantly poorer tooth brushing and sports participation than patients from any other participating country. Alcohol consumption, cigarette smoking and substance misuse were not significantly different. This study highlights lifestyle aspects that Maltese ACHD patients need to improve on, which might not be evident upon comparing patients to non-CHD controls. These findings should also caution researchers against considering behaviours among patients in one country as necessarily representative of patients on the larger scale.

Dental caries in fluorine exposure areas in China.

In this study, fluorine concentrations in drinking water and in urine of residents from a fluorine exposure area in China were tested. DMFT (average number of decayed, missing and filled teeth) of local residents in four age groups were also determined. The results of the study indicate that in fluorine exposure areas, there is a strictly positive correlation between fluorine content in urine and the fluorine content in drinking water. Effect of dental caries by high fluorine content drinking water is different for the different age groups. High fluorine content drinking water is more dangerous for 15-and 18-year-old groups than 5- and 12-year-old groups.

A preliminary study was conducted on 50 children in the age group of 4-12 years, who were divided into two groups on the basis of decayed, missing and filled teeth (DMFT) i.e. Group A (1-3) and Group B (> 3). A 5-day diet diary was evaluated and Sweet Score, Total Sugar Exposure, At Meal Sugar Exposures and Between Meal Sugar Exposure were calculated. There was statistically significant difference between the two groups in relation to Sweet Score and Total sugar Exposures. Between Meal Sugar Exposure and At Meal sugar exposure did not differ significantly.

Dental caries (tooth decay) is common and can be serious. Dental caries is preventable, and community water fluoridation is one means of prevention. There is limited current research on the implications of fluoridation cessation for children's dental caries. Our objective was to explore the short-term impact of community water fluoridation cessation on children's dental caries, by examining change in caries experience in population-based samples of schoolchildren in two Canadian cities, one that discontinued community water fluoridation and one that retained it. We used a pre-post cross-sectional design. We examined dental caries indices (deft [number of decayed, extracted, or filled primary teeth] and DMFT [number of decayed, missing, or filled permanent teeth]) among grade 2 schoolchildren in 2004/05 and 2013/14 in two similar cities in the province of Alberta, Canada: Calgary (cessation of community water fluoridation in 2011) and Edmonton (still fluoridated). We compared change over time in the two cities. For Calgary only, we had a third data point from 2009/10, and we considered trends across the three points. We observed a worsening in primary tooth caries (deft) in Calgary and Edmonton, but changes in Edmonton were less consistent and smaller. This effect was robust to adjustment for covariates available in 2013/14 and was consistent with estimates of total fluoride intake from biomarkers from a subsample. This finding occurred despite indication that treatment activities appeared better in Calgary. The worsening was not observed for permanent teeth. For prevalence estimates only (% with >0 deft or DMFT), the three data points in Calgary suggest a trend that, though small, appears consistent with an adverse effect of fluoridation cessation. Our results suggest an increase in dental caries in primary teeth during a time period when community fluoridation was ceased. That we did not observe a worsening for permanent teeth in the comparative analysis could reflect the limited time since cessation. It is imperative that efforts to monitor these trends continue.

ABSTRACT OBJECTIVE The objective of this study was to test the validity of the pragmatic criteria of the definitions of neonatal near miss, extending them throughout the infant period, and to estimate the indicators of perinatal care in public maternity hospitals. METHODS A cohort of live births from six maternity hospitals in the municipalities of São Paulo, Niterói, and Rio de Janeiro, Brazil, was carried out in 2011. We carried out interviews and checked prenatal cards and medical records. We compared the pragmatic criteria (birth weight, gestational age, and 5’ Apgar score) of the definitions of near miss of Pileggi et al., Pileggi-Castro et al., Souza et al., and Silva et al. We calculated sensitivity, specificity (gold standard: infant mortality), percentage of deaths among newborns with life-threatening conditions, and rates of near miss, mortality, and severe outcomes per 1,000 live births. RESULTS A total 7,315 newborns were analyzed (completeness of information > 99%). The sensitivity of the definition of Pileggi-Castro et al. was higher, resulting in a higher number of cases of near miss, Souza et al. presented lower value, and Pileggi et al. and de Silva et al. presented intermediate values. There is an increase in sensitivity when the period goes from 0–6 to 0–27 days, and there is a decrease when it goes to 0–364 days. Specificities were high (≥ 97%) and above sensitivities (54% to 77%). One maternity hospital in São Paulo and one in Niterói presented, respectively, the lowest and highest rates of infant mortality, near miss, and frequency of births with life-threatening conditions, regardless of the definition. CONCLUSIONS The definitions of near miss based exclusively on pragmatic criteria are valid and can be used for monitoring purposes. Based on the perinatal literature, the cutoff points adopted by Silva et al. were more appropriate. Periodic studies could apply a more complete definition, incorporating clinical, laboratory, and management criteria, including congenital anomalies predictive of infant mortality. PMID:29211204

[Give attention to standardized management of orbital development in Chinese with microphthalmos or anophthalmos].

Congenital and acquired microphthalmos or anophthalmos are common ocular disorders that cause facial disfigurement in children. It is important to have timely and reasonable treatment to promote orbital growth. At present status, many patients miss the optimum opportunity for orbital reconstruction because of non-standardized management in China. The correct management for promoting orbital growth in microphthalmos or anophthalmos is thus elaborated. Conformers with progressively increasing size can be used in children at 1-3 years of age; while orbital implants could be used after 3-5 years of age. Rational and regular evaluation of the efficacy is critical for guiding the treatment process.

Information about disease-specific and gender-associated differences over longer time of short children treated with recombinant human growth hormone is missing. We analyzed data at growth hormone (GH) start in prepubertal children diagnosed with idiopathic GH deficiency (IGHD), congenital GHD, acquired GHD, idiopathic short stature (ISS), and born small for gestational age (SGA) enrolled (1987-2012) in the Pfizer International Growth Study (KIGS®) from Europe, USA, and Japan. The demographic characteristics of patients in the three regions were similar. There was a diagnosis-specific pattern for age and height, and a universal pattern showing that girls were younger and smaller at GH start. There was a predominance of males with IGHD (n = 25,703; 70.1%), congenital GHD (n = 2,860; 63.9%), acquired GHD (n = 3,280; 63.9%), ISS (n = 4,327; 71.4%), and SGA (n = 5,848; 58.0%). Male prevalence in the USA population was more pronounced in IGHD, ISS, and SGA, but less so in congenital and acquired GHD. In IGHD (Europe and Japan) and ISS (Europe), there was a trend toward decreasing male prevalence. The male prevalence in prepubertal children treated with GH varies according to geographical region and is not explained by the underlying diagnoses. A global appreciation of gender biases is required for the proper care of short girls. © 2016 S. Karger AG, Basel.

Variability of the cranial and dental phenotype in Williams syndrome.

PubMed

Axelsson, Stefan

2005-01-01

Williams syndrome (WS) is a rare congenital disorder involving the cardiovascular system, connective tissue, and the central nervous system, resulting in mild to moderate mental retardation, a specific cognitive profile, unique personality characteristics, distinctive facial features, and cardiovascular disease. The majority of individuals with a clinical diagnosis of WS have a contiguous gene deletion at chromosome 7 (7q11.23). Physical features include characteristic facial features with full prominent cheeks, wide mouth, long philtrum, small nose with depressed nasal bridge, heavy orbital ridges, medial eyebrow flare, dental abnormalities, hoarse voice, growth retardation, and cardiovascular abnormalities (most commonly supravalvular aortic stenosis and/or peripheral pulmonary artery stenosis). The cognitive profile is distinctive, consisting of strengths in auditory memory, language, and face-processing, but extreme weakness in visuospatial, numerical and problem-solving abilities. Neurological studies have identified a significantly decreased brain volume in adult individuals with WS with relatively normal development of the limbic, frontal and cerebellar structures. The aims were to analyse the neurocranium, the craniofacial region, and the dentition in a well defined Norwegian group of individuals with WS. In order to accomplish this, normative cephalometric standards for the neurocranium, including the cranial base and the sella turcica, were established for Norwegian males and females from 6 to 21 years of age, using lateral radiographic cephalograms from the Oslo University Craniofacial Growth Archive. The study material comprised radiographic lateral cephalograms, orthopantomograms and dental casts from 62 individuals with WS ranging from 4 to 44 years. The lateral cephalograms, orthopantomograms and dental casts were analysed using standard methods reported in the literature. Neurocranium: The results from the cephalometric analyses showed that the size and shape of the neurocranium in WS differed from normal controls. A flattening of the superior aspect of the parietal bone was found and the posterior prominence of the occipital bone was larger. These findings were in concordance with published neuroanatomical/neuropathological studies on WS and fit well with the reported anatomical aberrations in the WS brain, e.g. a smaller brain volume where some parts are of relatively normal size while others are decreased. The anterior and posterior cranial base was shorter in WS, but with a normal cranial base angle. The thickness of the calvarian bones, especially the frontal and occipital bones, was greater in WS than in normal controls. Sella turcica: The size of the sella turcica was somewhat smaller in WS compared with normal controls, though not significant. Aberrant types of shape of the sella turcica in WS are demonstrated. The correlation between prenatal malformation in the pituitary gland/sella turcica and the postnatal morphology of the sella turcica is discussed. The craniofacial skeleton: Two areas, in addition to the cranial base, have been identified to contribute to the characteristic facial appearance in WS; the anterior inclination of the maxilla, and the shape of the mandible. The severely deficient bony chin in combination with the high mandibular plane angle can explain earlier clinical descriptions of a retrusive mandible in WS. Frequent mouth breathing during childhood and the smaller cranial base may be associated with the characteristic craniofacial pattern. Dentition: In individuals with WS over 10 years of age 40.5 per cent had agenesis of one or more permanent teeth and 11.9 percent had agenesis of 6 teeth or more. The missing permanent teeth in the maxilla most commonly included 2nd premolars, 1st premolars, and lateral incisors. In the mandible most commonly 2nd premolars, 1st premolars, and central incisors were absent. The tooth crowns of permanent teeth were smaller, both in the mesio-distal and labio-lingual dimension. The permanent tooth crowns have several characteristic deviations from normal shape; especially incisors in both jaws were tapered or screwdriver-shaped. An evaluation of taurodontism on permanent molars was performed. However, most of the molars rated as being taurodontic had short total tooth lengths and could thus be rated taurodontic without meeting the classical definition. These studies have shown aberrations in the neurocranium including the sella turcica in WS not previously reported. In the craniofacial skeleton specific traits have been identified to contribute to the characteristic facial appearance in WS. Dental aberrations in the permanent dentition including agenesis, smaller size, and aberrant shape of teeth, are common in WS.

The purpose of this study was to compare developmental defects of enamel (DDE) in the primary and permanent dentitions of children from a low-fluoride district. A total of 517 healthy schoolchildren were examined using the modified DDE criteria. The prevalence of DDE in the primary and permanent dentition was 25% and 58%, respectively (P<.001). The mean number of teeth with enamel opacity per subject was approximately threefold compared to that affected by enamel hypoplasia (3.1±3.8 vs 0.8±1.4, P<.001 in the primary dentition and 3.6±4.7 vs 1.2±2.2, P<.001 in the permanent dentition). Demarcated opacities (83%) were predominant compared to diffuse opacities (17%), while missing enamel was the most common type of enamel hypoplasia (50%), followed by grooves (31%) and enamel pits (19%) (P=.04). In the permanent dentition, diffuse and demarcated opacities were equally frequent, while enamel grooves were the commonest type of hypoplasia (52%), followed by missing enamel (35%) and enamel pits (5%; P<.001). In a low-fluoride community, developmental defects of enamel were twice as common in the permanent dentition vs the primary dentition. In the primary dentition, the predominant defects were demarcated opacities and missing enamel, while in the permanent dentition, the defects were more variable.

To examine whether late bedtime and short nighttime sleep duration at age 18 months are associated with risk of caries in deciduous teeth. Population-based cohort study using health check-up data of 71 069 children born in Kobe City, Japan, who were free of caries at age 18 months and had information on sleep variables at age 18 months and records of dental examinations at age 3 years. Sleep variables were assessed by standardized parent-reported questionnaires, and the incidence of caries in deciduous teeth was defined as the occurrence of at least 1 decayed, missing, or filled tooth assessed by qualified dentists without radiographs. Logistic regression was used to estimate the effects of late bedtime and short sleep duration on dental caries with adjustment for clinical and lifestyle characteristics. Overall, 11 343 (16.0%) cases of caries were observed at age 3 years. aORs for children with late or irregular bedtimes compared with those with bedtimes before 21:00 were 1.26 (95% CI 1.19-1.33), 1.48 (1.38-1.58), 1.74 (1.58-1.92), 1.90 (1.58-2.29), and 1.66 (1.53-1.81) for bedtimes at 21:00, 22:00, 23:00, 0:00, and irregular bedtime, respectively. aORs for children with short or irregular sleep duration compared with those with sleep duration of ≥11 hours were 1.30 (95% CI 1.15-1.47), 1.16 (1.09-1.24), 1.11 (1.05-1.18), and 1.35 (1.25-1.46) for sleep duration of ≤ 8, 9, 10 hours, and irregular sleep duration, respectively. In this exploratory study, late bedtime and short sleep duration were both consistently associated with increased risk of caries in deciduous teeth. Copyright © 2018 Elsevier Inc.

The purpose of this double-blind, cluster-randomized clinical trial was to examine the effects of xylitol gummy bear snacks on dental caries progression in primary and permanent teeth of inner-city school children. A total of 562 children aged 5-6 years were recruited from five elementary schools in East Cleveland, Ohio. Children were randomized by classroom to receive xylitol (7.8 g/day) or placebo (inulin fiber 20 g/day) gummy bears. Gummy bears were given three times per day for the 9-month kindergarten year within a supervised school environment. Children in both groups also received oral health education, toothbrush and fluoridated toothpaste, topical fluoride varnish treatment and dental sealants. The numbers of new decayed, missing, and filled surfaces for primary teeth (dmfs) and permanent teeth (DMFS) from baseline to the middle of 2nd grade (exit exam) were compared between the treatment (xylitol/placebo) groups using an optimally-weighted permutation test for cluster-randomized data. The mean new d(3-6)mfs at the exit exam was 5.0 ± 7.6 and 4.0 ± 6.5 for the xylitol and placebo group, respectively. Similarly, the mean new D(3-6)MFS was 0.38 ± 0.88 and 0.48 ± 1.39 for the xylitol and placebo group, respectively. The adjusted mean difference between the two groups was not statistically significant: new d(3-6)mfs: mean 0.4, 95% CI -0.25, 0.8), and new D(3-6)MFS: mean 0.16, 95% CI -0.16, 0.43. Xylitol consumption did not have additional benefit beyond other preventive measures. Caries progression in the permanent teeth of both groups was minimal, suggesting that other simultaneous prevention modalities may have masked the possible beneficial effects of xylitol in this trial. © 2014 S.

While research in terms of patient-centered care in implant therapy is growing, few studies have investigated patients' initial perceptions prior to consultation with the implant dentist. The aim of this cross-sectional study was to capture patients' initial information level, perceptions, as well as expectations from the implant therapy. A 34-item questionnaire was developed to investigate patients' preoperative information, perceptions and expectations from treatment with Dental Implants. The study was conducted in three locations (Hong Kong, SiChuan and JiangSu) during 2014-2015 with 277 patients. The main information source about implant therapy was the dentist or hygienist for less than half of the patients (n = 113, 42%). About 62.8% of participants considered that they were in general informed about implants, but only 17.7% felt confident with the information they had. More than 30% of the sample appeared to maintain dangerous misperceptions about Dental Implants: "Dental Implants require less care than natural teeth"; "Treatment with Dental Implants is appropriate for all patients with missing teeth"; "Dental Implants last longer than natural teeth"; and "Treatments with Dental Implants have no risks or complications." Patients were divided when asked whether "Dental Implants are as functional as natural teeth" (agreement frequency = 52.7%). Expectations from treatment outcome were commonly high, while there was a significant correlation between the overall mean of perception scores and outcome expectation scores (r = 0.32, P < 0.001). Overall, younger subjects (<45 years) and those with higher education level (bachelor and postgraduate) tended to present more realistic perceptions and lower outcome expectations. The majority of patients in this study presented relatively realistic perceptions. However, an alarming portion of the sample presented with inaccurate perceptions and unrealistic expectations, which the dental team would need to diagnose and correct prior to initiating implant treatment. © 2016 John Wiley & Sons A/S.

Previous studies have shown that persons having high Streptococcus mutans levels in the saliva are "at risk" for dental caries. Most investigators agree, that if high levels of S. mutans were identified early in the life of at-risk children, dental decay could be reduced or eliminated through intervention. The purpose of this study is to show an association between S. mutans levels and caries prevalence in a sample of elementary school children. The study group consisted of 242 school children, ages 5-13 years. The subjects were divided into two age groups, 5-8 years and 9-13 years. Approximately 59 percent were African Americans. The sample of 242 children were equally females and males, 50 percent in each group. The Dentocult SM Test was used to make S. mutans determinations. The df-t index was used to determine the number of decayed and filled teeth of children ages 5-8 years; the DMF-T Index estimated the number of decayed, missing or filled teeth of children ages 9-13 years. Dental caries were found in 58 percent of the children (mean = 2.67, and range of 1-11). Approximately 47 percent of the children with caries had high S. mutans levels (100K-1M). Females had higher S. mutans levels than males in the 9-13 age group, p < .05. Analysis of Variance Test indicated that S. mutans levels for older females (ages 9-13) were significantly higher than those observed in males the same age (p < .01). This trend was not observed in younger children, ages 5-8 years. In addition, no significant difference or interaction was noted by sex for S. mutans levels and decayed or filled teeth (df-t) for younger children. We conclude that high levels of Streptococcus mutans are related to increased number of decayed teeth and conversely, low Streptococcus mutans levels are related to fewer dental caries.

Dental caries remains a major public health problem in most industrialised countries, affecting 60% to 90% of schoolchildren and the vast majority of adults. Milk may provide a relatively cost-effective vehicle for fluoride delivery in the prevention of dental caries. This is an update of a Cochrane review first published in 2005. To assess the effects of milk fluoridation for preventing dental caries at a community level. We searched the Cochrane Oral Health Group Trials Register (inception to November 2014), the Cochrane Central Register of Controlled Trials (CENTRAL) (The Cochrane Library, 2014, Issue 10), MEDLINE via OVID (1946 to November 2014) and EMBASE via OVID (1980 to November 2014). We also searched the U.S. National Institutes of Health Trials Register (https://clinicaltrials.gov) and the WHO International Clinical Trials Registry Platform (http://apps.who.int/trialsearch) for ongoing trials. We did not place any restrictions on the language or date of publication when searching the electronic databases. Randomised controlled trials (RCTs), with an intervention and follow-up period of at least two years, comparing fluoridated milk with non-fluoridated milk. Two authors independently assessed trial risk of bias and extracted data. We used standard methodological procedures expected by The Cochrane Collaboration. We included one unpublished RCT, randomising 180 children aged three years at study commencement. The setting was nursery schools in an area with high prevalence of dental caries and a low level of fluoride in drinking water. Data from 166 participants were available for analysis. The study carried a high risk of bias. After three years, there was a reduction of caries in permanent teeth (mean difference (MD) -0.13, 95% confidence interval (CI) -0.24 to -0.02) and in primary teeth (MD -1.14, 95% CI -1.86 to -0.42), as measured by the decayed, missing and filled teeth index (DMFT for permanent teeth and dmft for primary teeth). For primary teeth, this is a substantial reduction, equivalent to a prevented fraction of 31%. For permanent teeth, the disease level was very low in the study, resulting in a small absolute effect size. The included study did not report any other outcomes of interest for this review (adverse events, dental pain, antibiotic use or requirement for general anaesthesia due to dental procedures). There is low quality evidence to suggest fluoridated milk may be beneficial to schoolchildren, contributing to a substantial reduction in dental caries in primary teeth. Due to the low quality of the evidence, further research is likely to have an important impact on our confidence in the estimate of effect and is likely to change the estimate. There was only one relatively small study, which had important methodological limitations on the data for the effectiveness in reducing caries. Furthermore, there was no information about the potential harms of the intervention. Additional RCTs of high quality are needed before we can draw definitive conclusions about the benefits of milk fluoridation.

Oral manifestations of hematologic and nutritional deficiencies can affect the mucous membranes, teeth, periodontal tissues, salivary glands, and perioral skin. This article reviews common oral manifestations of hematologic conditions starting with disorders of the white blood cells including cyclic hematopoiesis (cyclic neutropenia), leukemias, lymphomas, plasma cell dyscrasias, and mast cell disorders; this is followed by a discussion of the impact of red blood cell disorders including anemias and less common red blood cell dyscrasias (sickle cell disease, hemochromatosis, and congenital erythropoietic porphyria) as well as thrombocytopenia. Several nutritional deficiencies exhibit oral manifestations. The authors specifically discuss the impact of water-soluble vitamins (B2, B3, B6, B9, B12, and C), fat-soluble vitamins (A, D, and K) and the eating disorders anorexia nervosa and bulimia nervosa on the oral mucosa.

The tongue is an important oral structure that affects speech, position of teeth, periodontal tissues, nutrition, swallowing, nursing, and certain social activities. Ankyloglossia or tongue-tie, is a congenital anomaly characterized by an abnormally short lingual frenulum, which restricts mobility of the tongue. Though the ankyloglossia is not a serious condition, it may lead to a host of problems including infant feeding difficulties, speech disorders, and various mechanical and social issues related to the inability of the tongue to protrude. Hence, management of ankyloglossia should be considered at any age considering the risk-benefit evaluation. Tongue being highly vascular and mobile structure, laser-assisted lingual frenectomy is the simplest, safest and less traumatic of all the treatment modalities available, with most promising results in minimally invasive dentistry. Here, a case of ankyloglossia is reported with its management by diode laser.

Bayesian Multiscale Modeling of Closed Curves in Point Clouds

Gu, Kelvin; Pati, Debdeep; Dunson, David B.

2014-01-01

Modeling object boundaries based on image or point cloud data is frequently necessary in medical and scientific applications ranging from detecting tumor contours for targeted radiation therapy, to the classification of organisms based on their structural information. In low-contrast images or sparse and noisy point clouds, there is often insufficient data to recover local segments of the boundary in isolation. Thus, it becomes critical to model the entire boundary in the form of a closed curve. To achieve this, we develop a Bayesian hierarchical model that expresses highly diverse 2D objects in the form of closed curves. The model is based on a novel multiscale deformation process. By relating multiple objects through a hierarchical formulation, we can successfully recover missing boundaries by borrowing structural information from similar objects at the appropriate scale. Furthermore, the model’s latent parameters help interpret the population, indicating dimensions of significant structural variability and also specifying a ‘central curve’ that summarizes the collection. Theoretical properties of our prior are studied in specific cases and efficient Markov chain Monte Carlo methods are developed, evaluated through simulation examples and applied to panorex teeth images for modeling teeth contours and also to a brain tumor contour detection problem.

The aim of this study was to evaluate the dental health conditions of male employees in a large aluminum factory. The present report deals only with the periodontal findings. Five percent of the 181 examined subjects between 25 and 60 yr were edentulous, and all dentate individuals had some degree of periodontal disease. Surfaces harboring stainable plaque were high in all age groups, varying between 65 and 85%. Surfaces without retention factors were 31% and decreased with increasing age. The percentage of sites with bleeding increased from about 40% in the lowest to about 60% in the highest age group. Teeth with probing depths greater than or equal to 4 mm increased from about 30% in the age group 25-29 yr to about 45% in the age group 30-34 yr, after which it increased gradually with increasing age. The difference in bone scores (marginal bone loss) was the most extensive between the ages of 25 and 34 yr, but with a significant increase throughout the age groups. The administrators had a somewhat better oral hygiene, fewer retention factors, less bleeding, fewer pockets and some more marginal bone support than the workers. Still, the administrators had more missing teeth than the workers.

Since the first survey in 1992/93, the Swiss Health Survey (SHS) has been repeated every 5 years (1997, 2002 and 2007). In the present study, dental visits (dental care utilisation within the last 12 months), oral hygiene measures and the frequency of orthodontic treatments in the Swiss population in 2002 were examined and dental visits were compared with the years 1992/93, 1997 and 2007. Weighted data were analysed regarding different sociodemographic factors. From 1992 to 2002, dental visits among the 15-74-year-old declined continuously (1992/93: 70%, 1997: 66%, 2002: 63%), whereas in 2007 a slight increase (66%) was documented. In the survey from 2002, a large proportion (74%) of the population stated to clean their teeth or prostheses several times a day, predominantly with a manual toothbrush, whereas 28% applied an electric toothbrush and almost half of the respondents also used dental floss or toothpicks. Fewer visits and less intensive oral hygiene measures were observed among the elderly, men, weak social strata, smokers, persons with more than 8 missing teeth and in the group with removable dentures. Almost a quarter of the population had orthodontic treatment with the highest proportion among the 15-24-year-old (56%).

Ridge augmentation with soft tissue procedures in aesthetic dentistry: first clinical results measured with a new kind of moire technique

1993-09-01

The oral health of the Swiss population was significantly improved by the successful prevention of dental caries and periodontitis. Along with the healthy dentition the demand for aesthetic dentistry is increasing. Removable partial dentures are becoming less accepted. Therefore, to substitute lost teeth by permanent fixed partial prosthesis (bridges), the often deformed alveolar ridge has to be operated, either to improve the aesthetic appearance or to make it possible to restore the missing teeth by a fixed cemented bridge. The aim of this paper is (1) to evaluate whether the moire technique is an appropriate and handy method, and (2) to validate the precision of the new method. The measuring system consisted of a moire projector with an integrated phase shift device and a moire viewer with a CCD video camera, connected to a frame grabber in a personal computer. a highly versatile software was allowed to control the system as well as to grab the moire images using the four-phase shift technique in order to compute the phase image of the actual object. The new technique was validated with one solid test object measured by a 3D coordination, high precision measuring machine.

The Role of Genetic Factors in the Outbreak Mechanism of Dental Caries.

The aim of the present study was to investigate the relationships between cariogenic bacterial infection and single nucleotide polymorphisms (SNPs) in candidate genes associated with dental caries, and to explore the factors related to caries in children. Children aged 3 to 11 years were selected. Detection of cariogenic bacteria (Streptococcus mutans, Streptococcus oralis, Streptococcus sobrinus and Lactobacillus) from the plaque of each patient, and SNP analyses of five candidate genes (MBL2, TAS2R38, GLUT2, MMP13 and CA6) were performed using DNA isolated from buccal mucosal cells. The dental caries experience in primary and permanent teeth was determined using the decayed, missing and filled teeth (DMFT) index, and the effects of the observed factors on the DMFT value were analyzed by multiple regression analysis. The results of the multiple regression analysis showed that the DMFT value significantly increased in the presence of S. mutans or S. sobrinus (p < 0.001), while the dmft/DMFT value decreased in the presence of nucleobase C in MBL2 (p < 0.05). These results suggest that the MBL2 gene is related to the pathogenesis of dental caries.

The purpose of this study was to evaluate the influence of the masticatory system in patients with missing teeth. The influence of tooth loss on the masticatory system was analyzed with the use of bone scintigraphy ((99m)Tc-MDP) and histochemistry. Eight white rabbits (New Zealand, 12 weeks old) were used. The rabbits were divided into 2 groups: 6 weeks and 12 weeks. Teeth were extracted unilaterally in each rabbit under general anesthesia. Six and 12 weeks after extraction, scintigraphy was conducted, and the rabbits were killed and their masseter muscles removed for histochemical analysis. The results of bone metabolism (relative ratio) measured by bone scintigraphy were 48.27% at extraction sites and 51.73% at nonextraction sites at 6 weeks and 39.96% at extraction sites and 60.04% at nonextraction sites at 12 weeks. There was a significant difference at 12 weeks (P < .05). Tissue calcium contents and osteoclast counts showed different results between the extraction and nonextraction sites, but these differences did not reach statistical significance. The bone metabolism of temporomandibular joints and histochemical aspects of masticatory muscles may be associated with occlusal alterations following tooth loss. Copyright © 2012 Elsevier Inc.

Turkyilmaz, Ilser; Patel, Neal S.; McGlumphy, Edwin A.

2008-01-01

Due to the angulation of maxillary bone as the maxillary bone resorption occurs from a buccal to palatal direction, bucco-lingually tilted implant placement is more likely especially in the posterior maxilla. The aim of this paper was to present a case restored by using a maxillary hybrid denture using Cresco method. A 59-year-old woman with an edentulous maxilla and five missing mandibular teeth was referred for implant treatment. Six months after sinus lift operation, four mandibular implants and six maxillary implants were placed. Due to the bucco-lingual tilt of two implants, the Cresco method was chosen to fabricate the metal framework for the maxillary hybrid denture that was delivered four months after implant placement. The main advantages of the Cresco method are a perfectly passive framework fit and corrected screw access holes. All ten implants placed were considered successful at 1-year recall, and no screw access holes were seen in the buccal part of the maxillary acrylic teeth. It was concluded that such screw-retained maxillary hybrid denture using the Cresco method met the esthetic expectations of a highly demanding patient. PMID:19212552

In Australia, the majority of dental patients attend the private sector, while those with means tested eligibility for government assistance may attend the public sector. The aims of this study were to compare dental caries among persons who last visited private and public clinics, controlling for age, sex, reason for visit, and income. Data were collected in 2004-06, using a three-stage, stratified clustered sample of Australians aged 15+years, involving a computer-assisted telephone interview (CATI), oral examination, and mailed questionnaire. A total of 14,123 adults responded to the CATI (49 percent response) of whom 5,505 (44 percent of those interviewed) had an oral epidemiological examination. Multivariate regression analysis controlling for age, sex, reason for visit, and showed (P < 0.05) that persons attending public clinics had higher levels of decayed (beta = 0.33) and missing teeth (beta = 0.83), but lower levels of filled teeth (beta = -1.09) compared with the reference category of private clinics. Persons who attend for dental care in the public sector have worse oral health than adults who visit private dental clinics, in addition to an independent effect of socioeconomic disadvantage.

To assess salivary flow in older patients with type 2 diabetes mellitus (DM2) and its association with xerostomia. Cross-sectional clinical study conducted with older patients diagnosed with type 2 diabetes for at least one year receiving treatment at the Integrated Center for Diabetes and Hypertension of Ceará (CIHD) in the city of Fortaleza, Ceará, Northeastern Brazil. Oral clinical examination was carried out to assess the decayed, missing and filled teeth index (DMFT). Perception of the presence of xerostomia/dry mouth was assessed using the Visual Analogue Scale. Stimulated salivary flow was measured and samples were obtained using an extra-soft silicone device. 120 older patients with diabetes (60 insulin-dependent and 60 non-insulin-dependent) aged 65-91 years, with a mean age of 72.26 ± 6.53 years, were assessed. Of these, 111 (92.5%) presented a decrease in salivary flow while 59 (49.2%) reported moderate to severe xerostomia/dry mouth. The DMFT Index presented a mean of 27.53 ± 4.86 teeth. Reduced salivary flow was found in the group assessed in the present research; however, this finding is not in accordance with the perception of xerostomia/dry mouth reported by the patients.

Regenerative Medicine for Periodontal and Peri-implant Diseases

The balance between bone resorption and bone formation is vital for maintenance and regeneration of alveolar bone and supporting structures around teeth and dental implants. Tissue regeneration in the oral cavity is regulated by multiple cell types, signaling mechanisms, and matrix interactions. A goal for periodontal tissue engineering/regenerative medicine is to restore oral soft and hard tissues through cell, scaffold, and/or signaling approaches to functional and aesthetic oral tissues. Bony defects in the oral cavity can vary significantly, ranging from smaller intrabony lesions resulting from periodontal or peri-implant diseases to large osseous defects that extend through the jaws as a result of trauma, tumor resection, or congenital defects. The disparity in size and location of these alveolar defects is compounded further by patient-specific and environmental factors that contribute to the challenges in periodontal regeneration, peri-implant tissue regeneration, and alveolar ridge reconstruction. Efforts have been made over the last few decades to produce reliable and predictable methods to stimulate bone regeneration in alveolar bone defects. Tissue engineering/regenerative medicine provide new avenues to enhance tissue regeneration by introducing bioactive models or constructing patient-specific substitutes. This review presents an overview of therapies (e.g., protein, gene, and cell based) and biomaterials (e.g., resorbable, nonresorbable, and 3-dimensionally printed) used for alveolar bone engineering around teeth and implants and for implant site development, with emphasis on most recent findings and future directions.

OBJECTIVES: Oral health in Down syndrome children has some peculiar aspects that must be considered in the follow-up of these patients. This study focuses on characterizing the environmental and host factors associated with dental caries in Portuguese children with and without Down syndrome. METHODS: A sibling-matched, population-based, cross-sectional survey was performed. RESULTS: Down syndrome children presented a significantly greater percentage of children without caries, 78% vs. 58% of non-Down syndrome siblings. This difference in the DMFT index (number of decayed, missing and filled teeth) essentially reflects data obtained from treated teeth, for which 91% of children with Down syndrome had never had a tooth treated vs. 67% of siblings. This result was statistically significant, whereas results for decayed and lost teeth did not differ between Down syndrome children and their unaffected siblings. Additionally, in Down syndrome children, a delayed eruption of the second molar occurs. Down syndrome children and their siblings have similar oral hygiene habits, but a higher percentage of Down syndrome children visit a dentist before the age of three years, in comparison to their siblings. Bruxism was also more common in Down syndrome children compared to their siblings. CONCLUSIONS: Our results show that Portuguese children with Down syndrome have lower caries rates than children without Down syndrome. This reduced prevalence may be associated with the parents' greater concern about oral health care in Down syndrome children, resulting in their taking them sooner to visit a dentist, as well as to a higher bruxism prevalence and delayed tooth eruption.

An investigation undertaken into a sample of 1,115 five-year old children attending kindergartens in the city of Córdoba (Argentina) is described. The investigation aimed at establishing the prevalence and distribution of dental caries by socioeconomic level. Research showed that the prevalence of caries had decreased 55.0% in relation to the 1973 figure, while the proportion of children with healthy teeth was 26.7% greater. The frequency and seriousness of the caries increased as the child's social position declined. At the highest socioeconomic level NES I = entrepreneurial and managerial bourgeoisie), the rates of caries were significantly lower than those at the lowest socioeconomic level (NES III = typical proletariat, nontypical proletariat and sub-proletariat) presenting dmf-t of 0.8 and 2.7, and dmf-s of 0.9 and 4.9, respectively. In NES III, the dmf-t main components were decayed and missing teeth, while in NES I filled teeth were the main components. The proportion of children with no experience of caries was 63.1% in NES I and 11.5% in NES III. Inversly, the rate dental health was higher in NES I (8.8) than in NES III (5.1). The cost per child required for the restorative treatment in approximately two and a half times greater in NES III than in NES I. Considering the sample as a whole the expenditure required for NES III would be more than ten times higher than that required for NES I.(ABSTRACT TRUNCATED AT 250 WORDS)

The objective of this study was to estimate the prevalence of dental anomalies in primary dentition of Indian population. This cross-sectional study was conducted on 4180 children in the age of 2-6 years. Anomalies were classified based on Kreiborg criteria. The term "double tooth" was used to avoid misinterpretation between gemination. and fusion. Patients having radiographs were also examined for associated dental anomalies in permanent dentition. The occurrence and gender prevalence were evaluated using descriptive statistics. About 95. (2.27%) children exhibited at least one dental anomaly. Thirty.seven children showed 51 missing teeth. (0.88%), mostly in lower right incisors with a statistically significant difference between arches. (P = 0.0056) Nine children. (0.21%) had supernumerary teeth commonly in the right maxilla. Two cases of oligodontia. (0.04%) and talon cusps. (0.04%) and one case of triple tooth. (0.02%) were observed. Forty children. (0.95%) had 43 double teeth mostly in the right mandible with a statistically significant difference between the arches. (P = 0.0105). No significant difference was observed based on gender and arch, but they were statistically significant between the right and left sides. (P = 0.018). Among the children with radiographs available, 45% showed anomalies in the succedaneous dentition. The prevalence rates of children with double tooth, hypodontia, and hyperdontia in our study are 0.95%, 0.88%, and 0.21%, respectively. The overall prevalence rate of anomalies among boys was higher than girls.

Investigations about possible correlations between vegetarian diet and periodontal conditions are rare and characterized by small case numbers. The aim of this clinical study was to investigate the influence of a vegetarian diet on periodontal parameters with an appropriate sample size. A total of 200 patients, 100 vegetarians and 100 non-vegetarians, were included in the study. All patients were examined including a full mouth assessment of the periodontal and dental conditions. In addition, a questionnaire was handed out to ask for patients' oral hygiene habits and level of education. For statistical analysis the Mann-Whitney Test (χ(2) for analysis of the questionnaire) was applied (level of significance: P<0.05). Well known periodontal risk factors like age, gender and smoking habits were equally distributed within each group (71 females, 29 males, respectively and 10 smokers in each group; mean age: 41.45 years vegetarians versus 41.72 years non-vegetarians). Vegetarians had significantly lower probing pocket depths (P=0.039), bleeding on probing (P=0.001), periodontal screening index (P=0.012), a better hygiene index (P<0.001) and less mobile teeth (P=0.013). Dental examinations revealed significantly less missing teeth (P=0.018) but also more decayed (P=0.001) and eroded (P=0.026) teeth in vegetarians. Furthermore, vegetarians had a higher level of education (P<0.001), but visited dentists significantly less frequent. Vegetarians revealed better periodontal conditions (less inflammation signs, less periodontal damage and a better dental home care). However, it should be considered that vegetarians are not only avoiding meat in their nutrition but are also characterized by an overall healthier life style.

The aim of this study is to examine whether oral hygiene and self-care, particularly in periodontal health, are associated with chronic obstructive pulmonary disease (COPD) in the Korean population. Data from the Korean National Health and Nutrition Examination Survey from 2010 to 2012 were used to assess the community periodontal index (CPI) of 5,878 participants (normal lung function: n = 5,181; obstructive spirometric pattern: n = 697) aged ≥40 years, who underwent spirometry. Participants with COPD brushed their teeth less frequently and used the following less frequently: 1) dental floss and/or interdental brush; 2) mouthwash; and 3) electric toothbrush (P <0.001). Prevalence of periodontitis in patients with COPD (58.1%) was significantly higher than in those without COPD (34.0%, P <0.001). Number of teeth was significantly lower in patients with COPD compared with controls. Decayed-missing-filled tooth index was significantly lower in patients with COPD. This study shows risk of COPD by periodontal severity. Periodontitis (CPI 3 and 4) was associated in males with COPD after adjustment for: 1) age; 2) income; 3) education; 4) smoking; 5) alcohol consumption; 6) exercise; 7) body mass index; 8) toothbrushing frequency; 9) diabetes mellitus; and 10) number of teeth (CPI 3: relative risk [RR] = 1.38, 95% confidence interval [CI] = 1.12 to 2.05; CPI 4: RR = 1.23, 95% CI = 1.06 to 1.56). Findings of this cross-sectional study suggest that COPD in males may be associated with severe periodontitis and indicates the importance of promoting dental care in patients with COPD.

This case report describes the successful treatment of a severe chronic periodontitis case by nonsurgical therapy and a strict maintenance program over a 12-year period. A 38-year-old man concerned about the protrusion of his maxillary incisors was referred for periodontal treatment. The teeth in the maxillary arch had generalized severe chronic periodontitis. Several treatment options were presented to the patient including the most aggressive, extraction of all maxillary teeth, and the most conservative, scaling and root planing. The patient opted to having the most conservative approach, even though the prognoses for the maxillary teeth were unfavorable. Therefore, he received nonsurgical therapy via scaling and root planing combined with systemic antibiotics before referral to an orthodontist to address the esthetic concerns. The maxillary dentition was treated with orthodontic therapy to retract and align the maxillary anterior segment. Periodontal maintenance (1-hour session), including subgingival instrumentation, was performed 4 times per year until the end of the 12-year follow-up period. The patient only missed 2 appointments in 12 years. Twelve years later, the results revealed that all but 1 maxillary tooth were maintained in a state of acceptable health, function, and esthetics. Although most would agree with the initial poor prognosis of this patient's case, nonsurgical periodontal therapy was utilized with a 3-month periodontal maintenance program and demonstrated long-term success. The outcome presented in this case report may only have been possible because of patient compliance, professional experience, skill, and supervision throughout the course of treatment.

Background Paranoid schizophrenia is a mental illness that involves no observable anatomical alteration. Main characteristic affects the personality of the individual, as well as areas of his own psychology. Case Report A 33-year-old man with paranoid schizophrenia and obsessive-compulsive disorder in treatment with Haloperidol, Oxcarbazepine, Olanzapine and Seroquel is presented. Dental exploration showed widespread decay mostly cervical with numerous root fragments, agenesis of lateral incisors, impacted wisdom teeth, missing teeth and malocclusion. Treatment plan included restoration of teeth decay, extractions of root fragments and implant-supported prostheses in bilateral upper lateral incisors for aesthetics reason. A previous consultation with a psychiatric specialist was performed and no contraindication were observed. A preliminary radiological examination was performed previous dental treatment and implant placement. Due to patient refusal to replace dental abscenses with implants, inform consent was signed up from his parents. After local anesthesia, first implant was placed at upper right lateral positions (Straumann Bone Level Ø 3.3 mm, length 10 mm). Two weeks later a second implant was placed at upper left lateral position (Straumann Bone Level Ø 3.3 mm, length 12 mm). The patient showed no postoperative complications. After implant placement, the patient attended scheduled review appointments. The prosthesis was placed after a 3-month period of osseointegration. Conclusions Implant placement can be considered a suitable option for people with mental disorders. A previous consultation with psychiatric specialists for conducting a good patient management is necessaire. Key words:Paranoid schizophrenia, obsessive-compulsive disorder, dental implants.

To conduct a systematic review of randomised trials assessing the association between personal oral hygiene and dental caries in the absence of the confounding effects of fluoride. Dental caries continues to affect close to 100% of the global population. There is a century-old conflict on whether dental caries is caused by poor oral hygiene or poorly formed teeth (ie, teeth with dental defects). Resolving this conflict is of significant public health importance as these two hypotheses on dental caries aetiology can lead to different prevention strategies. A systematic search for randomised trials was conducted using predefined criteria in 3 databases. The impact of personal oral hygiene interventions on coronal dental caries incidence was evaluated using random-effects models. Three randomised studies involving a total of 743 participants were included. Personal oral hygiene interventions failed to influence the incidence of dental caries (Δ Decayed, Missing and Filled Surfaces (DFMS) = -0.11; 95% confidence interval: (-0.91, 0.69; P-value < .79)) despite meticulous deplaquing of teeth. There was no significant heterogeneity in the trial results (heterogeneity chi-squared = 1.88, P = .39). The findings were robust to sensitivity analyses, including consideration of the results of nonrandomised studies. Personal oral hygiene in the absence of fluorides has failed to show a benefit in terms of reducing the incidence of dental caries. © 2018 The Authors.

Odontomas are benign odontogenic tumors composed of enamel, dentine, and cementum and pulp tissue. They are usually clinically asymptomatic, but often associated with tooth eruption disturbances. The present study reports an unusual case of eleven odontomas in the left lateral incisor-canine region of lower jaw. A 26 years old female presented to the department of orthodontics and dentofacial orthopedics in H.P. Govt. Dental College and Hospital Shimla for the treatment of misaligned teeth. Clinical examination revealed that the lower left lateral incisor was missing. Patient was advised for radiographs, which revealed a mixed radiopaque lesion associated to impacted lower left canine. The histological report in this case indicated a compound odontoma. PMID:23293496

Inherited dental malformations constitute a clinically and genetically heterogeneous group of disorders. Here, we report on a severe developmental dental defect that results in a dentin dysplasia phenotype with major microdontia, oligodontia, and shape abnormalities in a highly consanguineous family. Homozygosity mapping revealed a unique zone on 6q27-ter. The two affected children were found to carry a homozygous mutation in SMOC2. Knockdown of smoc2 in zebrafish showed pharyngeal teeth that had abnormalities reminiscent of the human phenotype. Moreover, smoc2 depletion in zebrafish affected the expression of three major odontogenesis genes: dlx2, bmp2, and pitx2. PMID:22152679

Evaluation of age of unknown deceased persons belongs to the most important ways to identification. For the time being, morphological methods are used, namely evaluation of age according to Gustafson's method from tooth grindings or by macroscopical estimation of abrasion, transparency of root dentine, alveolar atrophy and number of missing teeth. Evaluation of the data can be influenced by an individual failure and experience showed an age related decrease of precision. Recently, some papers occurred estimating a relation of D, L-forms of aspartic acid which depends on the age with a significant precision.

Cleansing and surface modifying agents on implants: fixation and related aspects of aesthetics.

With the prognosis of dental implant replacement of missing teeth becoming better each year, practitioners are focusing their attention on the aesthetic aspects of implantology. However, improvement in aesthetics is only possible with the improvement in implant technology, surgical techniques and prosthodontic procedures. This study aimed at evaluating the effects of various physical and chemical agents on the implant surface; with the view of obtaining increased surface area and biocompatibility. The study found that the treatment of air-aluminum oxide blasted implants using a mixture of 30% HNO3-5% HF acids produced a surface which meets the consideration of aesthetics for implants placed in the anterior maxillary region.

Treatment of Orally Handicapped Edentulous Older Adults Using Dental Implants.

Zahedi, Charles

2016-07-01

The oral handicap of complete edentulism is the terminal outcome of a multifactorial process involving biological factors and patient-related factors. Fully edentulous orally handicapped older adults have been neglected because removable acrylic dentures have been the classic therapy for complete edentulism but are only rehabilitative, not therapeutic. Not replacing missing teeth with stable dentures could prevent adequate food intake. Osseointegrated endosseous implants used as a therapeutic adjunct can reduce the problem of long-term bone resorption to less than 0.1 mm per year. Implant-borne prostheses substantially increase the overall health and quality of life of orally handicapped fully edentulous older adults. Copyright © 2016 Elsevier Inc. All rights reserved.

Objective: To compare the long-term dental treatment effects, oral health habits and oral-health-related qualities of life of children treated under general anesthesia (GA) and passive restraint (PR), respectively. Methods: Twenty seven 2 to 4-year-old children treated under GA and thirty four children treated under PR were recruited in the Department of Pediatric Dentistry, Peking University School and Hospital of Stomatology. Up to 2 years after the treatment, a follow up assessment was conducted. The data of general information, dental plaque level and the unplanned treatments were recorded and analyzed. The questionnaire of oral health habits and early childhood oral health impact scale (ECOHIS) for each child was also completed and analyzed. The survival rate and median survival time of the deciduous teeth were calculated. Multivariate analysis was performed by using Cox proportional hazard model. Results: Twenty-five children under GA and 32 under PR were finally included, with a total of 1 098 deciduous teeth. The postoperative dental plaque indicesin both GA and PR groups had significantly improved than that of before the treatments ( P= 0.019, P< 0.001). The oral health habits had also improved, and the improvement in PR group was more obvious than that in GA group. Totally 128 teeth (27.0%) appeared unplanned treatments in GA group and 232 teeth (37.2%) in PR group during the follow-ups. The new caries and recurrent caries in PR group were significantly more than that in GA group ( P< 0.001, P= 0.012). No significant differences were found between the two groups in restoration failure, secondary caries and endodontic diseases ( P= 0.129, P= 0.822, P= 0.642). However, the time of occurrence of endodontic disease and secondary caries in GA group were significantly longer than that in PR group ( P< 0.01, P< 0.001). The median survival time of teeth in GA group was 1 018 days comparing to 944 days in PR group. The difference was statistically significant ( P< 0.05). The survival rate was associated with such factors as decayed-missing-filled tooth (dmft), anterior or posterior teeth, feeding frequency, brushing habits and behavior management techniques. Conclusions: The long-term dental treatment effects of children treated under GA was significantly better than that of PR group. Continuous reinforcement of proper dietary and oral hygiene habits might help in maintaining the long-term treatment effect.

Language acquisition after cochlear implantation of congenitally deaf children: Effect of age at implantation

Svirsky, Mario; Holt, Rachael

2005-04-01

Evidence shows that early implantation of congenitally deaf children is beneficial. However, infants as young as 6 months of age have started to receive cochlear implants (CIs) in the USA. Such early implantation may be associated with higher risks, including anesthetic risk as well as the increased possibility of a false positive in the diagnosis of profound deafness. On the other hand, delaying implantation may be associated with the risk of missing windows of opportunity or sensitive periods for the development of communication skills. In this study, speech perception and language skills in children who received CIs in the first, second, third, or fourth year of life were compared. Participants were tested at regular 6-month intervals after implantation. The effects of several potential confounds were considered. In general, children implanted earlier outperformed those implanted later, with one exception: infants implanted at 6-12 months showed similar outcomes to children implanted at 12-24 months, at least through 2 to 2-1/2 years of age. This preliminary result may be associated with the difficulty of choosing appropriate stimulation parameters for infants, and its potential influence on the quality of the stimulation patterns delivered by the CI.

We describe a prenatal ultrasonography diagnosis of omphalocele and symbrachydactyly in a fetus and review the literature on prenatal diagnosis of 9p terminal chromosomal deletions. A 31-year-old woman (gravida 3, para 1) was referred for genetic counseling because a fetal omphalocele had been detected. Prenatal ultrasonography at 17+ weeks of gestational age revealed a singleton female fetus with biometry equivalent to 18 weeks with an omphalocele. In addition, symbrachydactyly was also noted in the right arm; the wrist bones as well as the metacarpals were missing. A chromosomal study was arranged for a congenital anomaly involving omphalocele. We obtained Giemsa-banded chromosomes from fetal tissue cells, and an abnormal male karyotype with a terminal deletion of the short arm of chromosome 9 at band 9p13 was noted. After delivery, the fetus showed omphalocele, symbrachydactyly, trigonocephaly, sex reversal, a long philtrum, low-set ears, telecanthus, and a frontal prominence. Prenatal diagnosis of abnormal ultrasound findings with omphalocele and symbrachydactyly should include the differential diagnosis of a chromosome 9p deletion. Copyright © 2014.

Due to the lack of paediatric-licensed formulations, children are often treated with individualized pharmacy-compounded adult medication. An international web-based survey about the types of medication in children with adrenal insufficiency (AI) revealed that the majority of paediatric physicians are using pharmacy-compounded medication to treat children with AI. Observations of loss of therapy control in children with congenital adrenal hyperplasia with compounded hydrocortisone capsules and regained control after prescribing a new hydrocortisone batch led to this 'real world' evaluation of pharmacy-compounded paediatric hydrocortisone capsules. Capsule samples were collected randomly from volunteering parents of treated children suffering from congenital adrenal hyperplasia from all over Germany. Analysis of net mass and hydrocortisone content by high-performance liquid chromatography with ultraviolet (HPLC-UV) detection method was performed based on the European Pharmacopeia. In a total of 61 batches that were sent, 5 batches could not be analysed because of missing dose information, insufficient number of capsules or were not possible to be evaluated. Fifty-six batches containing 1125 capsules were evaluated. 21.4% of the batches revealed insufficiency in uniformity of net mass or drug content and additional 3.6% failed because they did not contain the labelled drug. Compounded medication is a possible cause of variation of steroid doses in children with adrenal insufficiency or congenital adrenal hyperplasia, putting these vulnerable patients at risk of poor disease control and adrenal crisis. These data may apply to other individualized compounded oral medication as well, emphasizing the need for development of licensed paediatric formulations approved by regulatory authorities. © 2017 European Society of Endocrinology.

Background We conducted a study of congenital Trypanosoma cruzi infection in Santa Cruz, Bolivia. Our objective was to apply new tools to identify weak points in current screening algorithms, and find ways to improve them. Methods Women presenting for delivery were screened by rapid and conventional serological tests. For infants of infected mothers, blood specimens obtained on days 0, 7, 21, 30, 90, 180, and 270 were concentrated and examined microscopically; serological tests were performed for the day 90, 180, and 270 specimens. Maternal and infant specimens, including umbilical tissue, were tested by polymerase chain reaction (PCR) targeting the kinetoplast minicircle and by quantitative PCR. Results Of 530 women, 154 (29%) were seropositive. Ten infants had congenital T. cruzi infection. Only 4 infants had positive results of microscopy evaluation in the first month, and none had positive cord blood microscopy results. PCR results were positive for 6 (67%) of 9 cord blood and 7 (87.5%) of 8 umbilical tissue specimens. PCR-positive women were more likely to transmit T. cruzi than were seropositive women with negative PCR results (P < .05). Parasite loads determined by quantitative PCR were higher for mothers of infected infants than for seropositive mothers of uninfected infants (P < .01). Despite intensive efforts, only 58% of at-risk infants had a month 9 specimen collected. Conclusions On the basis of the low sensitivity of microscopy in cord blood and high rate of loss to follow-up, we estimate that current screening programs miss one-half of all infected infants. Molecular techniques may improve early detection. PMID:19877966

Intravenous bisphosphonate-related osteonecrosis of the jaws: Influence of coadjuvant antineoplastic treatment and study of buccodental condition

Bagán, José; Poveda-Roda, Rafael

2013-01-01

Objectives: To determine whether coadjuvant antineoplastic treatment can influence the number and size of bone exposures among patients with intravenous bisphosphonate-related osteonecrosis of the jaws (iBRONJ), and to analyze the buccodental condition of these patients. Material and methods: The study sample comprised 67 patients with iBRONJ, 53 patients without iBRONJ receiving treatment with intravenous bisphosphonates, and 36 healthy subjects. In all three groups, measurements were made of the CAO index and of resting whole saliva and stimulated whole saliva. In the patients with iBRONJ, the size (cm) and number of bone exposures were recorded. The data obtained were subjected to analysis of variance (ANOVA), the Mann-Whitney U-test, and multivariate logistic regression analysis. Results: A total of 57.6% of the patients presented single bone exposure, 25.4% presented two, and 17% more than two exposures. The mean exposure size was 2.3±1.9 cm. Neither the bivariate analysis nor the multivariate multiple regression analysis found coadjuvant antineoplastic treatment to exert a statistically significant effect upon the number and size of bone exposures. On the other hand, there were statistically significant differences among the three study groups in relation to the CAO index (p=0.02) and the number of missing teeth (p=0.00). The resting whole saliva and stimulated whole saliva levels were similar in the three groups, though the patients with osteonecrosis of the jaws showed comparatively lower SWS levels. Conclusions: Coadjuvant antineoplastic treatment alone appears to exert no influence upon the size and number of bone exposures in iBRONJ. The patients with this disease show a higher CAO index and a larger number of missing teeth. Key words:Osteonecrosis of the jaws, bisphosphonates, bone exposure, CAO index, resting whole saliva, stimulated whole saliva. PMID:23229272

The number of dental implants inserted annually worldwide has been estimated to come close to a million. But the level of information available to patients about realistic, evidence-based treatment options by implants is often enough more than fragmentary, and what is disseminated by the media and the industry does not always reflect evidence-based empirical data. This survey of 1000 adults presented with 18 questions was designed to shed light on several points. These were (1). level of subjective patient information, (2). sources of information and prejudices, (3). future demand for implant treatment and target groups for patient information campaigns, and (4). potential misinformation, information deficits, discrepancies of information and how these come about. Of those questioned, 20% said unprompted that implants were a possibility to replace missing teeth. When prompted, 72% said that they knew about dental implants. Most of those questioned felt poorly informed about the options for replacing missing teeth and many knew less about implants than about other alternatives. The dentist was said to be the desired source of information, but 77% of those questioned reported that their dentists did not practice implant dentistry. More than 79% of those questioned did not know whether their dentist worked with implants. Forty-four percent thought that implants should only be placed by specially trained doctors. Sixty-one percent were of the opinion that dentists who provide implant dentistry were better qualified than their nonimplanting colleagues. Half of those questioned attributed implant failures to allergies and incompatibilities, the other half to poor medical care. Only 29% incriminated poor oral hygiene as a cause of implant failure. Future strategies should be geared to more professional public relations and patient information. Internationally operating qualified implant institutions could contribute much to balance discrepant information.
