The demand for preventive and restorative dental services.  

PubMed

Chronic tooth decay is the most common chronic condition in the United States among children ages 5-17 and also affects a large percentage of adults. Oral health conditions are preventable, but less than half of the US population uses dental services annually. We seek to examine the extent to which limited dental coverage and high out-of-pocket costs reduce dental service use by the nonelderly privately insured and uninsured. Using data from the 2001-2006 Medical Expenditure Panel Survey and an American Dental Association survey of dental procedure prices, we jointly estimate the probability of using preventive and both basic and major restorative services through a correlated random effects specification that controls for endogeneity. We found that dental coverage increased the probability of preventive care use by 19% and the use of restorative services 11% to 16%. Both conditional and unconditional on dental coverage, the use of dental services was not sensitive to out-of-pocket costs. We conclude that dental coverage is an important determinant of preventive dental service use, but other nonprice factors related to consumer preferences, especially education, are equal if not stronger determinants.

Dental fluorosis: Exposure, prevention and management  

Microsoft Academic Search

Dental fluorosis is a developmental disturbance of dental enamel, caused by successive exposures to high con - centrations of fluoride during tooth development, leading to enamel with lower mineral content and increased porosity. The severity of dental fluorosis depends on when and for how long the overexposure to fluoride occurs, the individual response, weight, degree of physical activity, nutritional factors

Reflections on a training course reorienting dental teams towards prevention.  

PubMed

Prevention is a core element of routine dental practice. However, members of the dental team often lack the required knowledge and skills to deliver effective evidence-based advice and support to patients. This paper describes the development and delivery of an innovative course designed to develop the preventive capacity of dental teams working in dental foundation training practices across London. The course contents were based upon national guidelines on evidence-based preventive care delivered in primary dental care settings (Delivering better oral health). An experienced team of trainers from diverse backgrounds successfully designed and delivered the courses and the initial feedback from participants indicate strong support for the approach developed.

Challenges of Iranian Adolescents for Preventing Dental Caries  

PubMed Central

Background: Oral health plays a vital role in people’s general health and well-being. With regard to the costly treatments of oral diseases, preventive programs need to be designed for dental caries based on children’s perspectives. Objectives: The purpose of this study was to describe and explore challenges for caring dental health based on children’s perspectives. Patients and Methods: A qualitative design with content analysis approach was applied to collect and analyze the perspectives of students about factors influencing oral and dental care. Eighteen Iranian students in 8 guidance schools were chosen through the purposive sampling. Semi-structured interviews were held for data gathering. In order to support the validity and rigor of the data, different criteria such as acceptability, confirmability, and transferability were utilized. Results: During data analysis, four main themes developed: “barriers to dental health,” “maintaining dental health,” “uncertainty in decision-making” and “supportive factors”. “Uncertainty in decision-making” and “barriers to dental health” were the main challenges for preventing dental caries among adolescents. Conclusions: “Certainty in decision-making” to maintain dental health depends on overcoming the barriers of dental health. Further research is needed to confirm the findings of this study.

Taekwondo coaches knowledge about prevention and management of dental trauma.  

PubMed

The aim of this study was to assess level of knowledge about prevention and dental trauma management among taekwondo coaches in Croatia. The questionnaire submitted to the taekwondo coaches contained 16 items about dental trauma prevention and management. The questionnaires were filled in by 131 taekwondo coaches; 28 females and 103 males. Descriptive statistics was used to describe and analyze the obtained data. The coaches were familiar with dental injuries in high percentage: 41 (31.3%) have observed dental injury and 36 (27.5%) have experienced a dental injury themselves. Eight of them had tooth avulsion, fourteen crown fracture, and eight had tooth luxation. About half of all interviewed coaches 68 (52.7%) were aware of the possibility of replanting avulsed teeth. Twenty six (19.8%) were familiar with the tooth rescue kit. Only 99 out of 131 coaches (75.6%) have used a mouthguard. The obtained results show low knowledge about possibilities for prevention of dental trauma. Insufficient use of mouthguards in this contact sport requires more attention of dentists and coaches education about dental trauma prevention. PMID:25145007

The reliability and validity of the RAPIDD scale: readiness assessment of parents concerning infant dental decay.  

PubMed

This study assessed the instrument, Readiness Assessment of Parents concerning Infant Dental Decay (RAPIDD), as a measure of parental readiness to change children's dental behaviors. The 38-item instrument based on four constructs (Openness to Health Information, Valuing Dental Health, Convenience/Difficulty, Child Permissiveness) was administered to a random sample of parents of 6-to-36 month old children on Saipan, Commonwealth of the Northern Mariana Islands, USA. Alpha values for each construct's internal consistency ranged from 0.51 to 0.75. Correlations were found with feeding (e.g., Convenience/Difficulty and receiving bottle (r = .24, p < 0.01)) and oral hygiene (e.g., Valuing Dental Health and tooth-cleaning (r = .27, p < 0.01)). Parental responses were used to categorize respondents into precontemplators (16 percent), contemplators (77 percent), and actions (6.7 percent). This categorization was associated with the number of decalcified and decayed surfaces (alpha 2 = 34.8, p = 0.04; alpha 2 = 65.7, p < 0.01). This suggests that parental readiness is associated with infant dental health and that most parents would be willing to contemplate prevention. PMID:11475689

Perceived barriers to preventive dental care among Libyan dentists  

PubMed Central

Aim To explore the barriers to providing preventive dental care to patients, as perceived by Libyan dentists working in Benghazi. Settings and design A cross-sectional, questionnaire-based survey was conducted among dentists working in Benghazi, Libya. Materials and methods All dentists registered with the Dental Association of Benghazi and with 2 or more years of practice were invited to participate. The questionnaire collected information on participants’ demographic and professional characteristics as well as the patient-, practice- and dentist-related barriers to providing preventive dental care. Statistical analysis Scores for each type of barrier were compared by demographic and professional characteristics in bivariate and multivariate analyses. Results One hundred and seventy five dentists returned the questionnaires (response rate: 79%) and 166 had complete information on all the variables selected for analysis (75%). The majority were females (70%), aged between 23 and 34 years (85%), was working in the public health sector (43%), and had up to 5 years of service (46%). Patient-related barriers were scored the highest, followed by practice- and dentist-related barriers. Dentists with mixed practice reported lower scores on patient- and practice-related barriers than those in public or private practice. Conclusion Respondents were generally aware of the barriers to preventive dentistry and perceived the barriers as being more related to their patients than to their practices or themselves. However, these perceptions varied by practice sector. PMID:24767673

Dental caries and periodontal disease (prevention and control methods).  

PubMed

There is a compelling need to apply preventive programs in both private and community practice of dentistry. This is to maintain improvements in oral health in developed and industrialized countries, and to stem increases in oral diseases in underserved and developing ones. At the outset, the terms prevention and control must be understood. The former is considered to mean a procedure or course of action that prevents the onset of disease, whereas the latter, implies reversing or stabilizing disease conditions. To be more precise, prevention will refer to the pre-pathologic or pre-clinical stage encompassing the promotive and specific protection levels--primary prevention stage. On the other hand, control will encompass early diagnosis and prompt treatment, disability limitation and rehabilitation levels-termed also collectively, as pathologic, clinical and final stages, or secondary and tertiary prevention. Community-based programs are usually structured to compliment therapeutic interventions of oral diseases, as well as prevention. In this era, and towards the next millennium, preventive and control programs are given high priorities in order to minimize the need for curative, restorative and therapeutic management of oral diseases. This review of the literature will give emphasis on established methods and programs for the prevention and control of the two most common oral diseases, dental caries and periodontal disease. The problems, background, and oral health objectives for the year 2000 as proposed by the World Health Organization (WHO) and the Federation Dentaire Internationale (FDI), as well as the recent advances in oral health relative to these diseases will be discussed. Finally, to better improve the efficacy of existing prevention and control methods, research needs and areas of concern relative to these diseases will be given consideration. PMID:10808358

Dental injuries in inline skating - level of information and prevention.  

PubMed

Inline skating belongs like ice hockey, rugby, and boxing to sporting activities with high-risk of suffering tooth accidents. Because of high velocity and loss of balance, especially on uneven ground, the injury potential in inline skating is higher. The objective of this work was to conduct a comparative study between Switzerland and Germany. The questions focussed on the frequency of tooth accidents, their prevention by mouthguard and the level of information about emergency measures after dental trauma and the resulting consequences for athletes. Using a standardized questionnaire totally 612 individuals, 324 men and 288 women, in two countries belonging to three different divisions (fun, fitness and speed) were surveyed. Fifty-six (9.2%) of these 612 interviewees have already experienced a tooth injury while inline skating. More than half of all interviewed players (68.3%) were aware of the possibility of replanting avulsed teeth. Only 32.4% were familiar with the tooth rescue kit. Just 65.4% knew mouthguard and only 1.9% of those athletes (n = 12) wore a mouthguard while inline skating. The results show that the area of inline skating requires more information about preventing dental trauma through sports associations and dentists. PMID:17511835

Determinants of preventive oral health behaviour among senior dental students in Nigeria  

PubMed Central

Background To study the association between oral health behaviour of senior dental students in Nigeria and their gender, age, knowledge of preventive care, and attitudes towards preventive dentistry. Methods Questionnaires were administered to 179 senior dental students in the six dental schools in Nigeria. The questionnaire obtained information on age, gender, oral self-care, knowledge of preventive dental care and attitudes towards preventive dentistry. Attending a dental clinic for check-up by a dentist or a classmate within the last year was defined as preventive care use. Students who performed oral self-care and attended dental clinic for check-ups were noted to have complied with recommended oral self-care. Chi-square test and binary logistic regression models were used for statistical analyses. Results More male respondents agreed that the use of fluoride toothpaste was more important than the tooth brushing technique for caries prevention (P < 0.001). While the use of dental floss was very low (7.3%), more females were more likely to report using dental floss (p=0.03). Older students were also more likely to comply with recommended oral self-care (p<0.001). In binary regression models, respondents who were younger (p=0.04) and those with higher knowledge of preventive dental care (p=0.008) were more likely to consume sugary snacks less than once a day. Conclusion Gender differences in the awareness of the superiority of using fluoridated toothpaste over brushing in caries prevention; and in the use of dental floss were observed. While older students were more likely to comply with recommended oral self-care measures, younger students with good knowledge of preventive dental care were more likely to consume sugary snacks less than once a day.

Perceived competency towards preventive dentistry among dental graduates: the need for curriculum change  

PubMed Central

Background A previous study has shown that dental practitioners in Benghazi believed that the less prevention-oriented education system is one of the barriers to applying preventive dentistry. Objective To assess attitudes and perceived competence of the dental graduates in Benghazi towards prevention and early management of dental caries. Methods A cross-sectional, questionnaire-based survey was conducted among internship students attending the Department of Community and Preventive Dentistry in Faculty of Dentistry, Benghazi, Libya. The participants were asked to provide demographic information, to respond to statements about their attitudes towards preventive dentistry, and to answer questions regarding their perceived competence in applying preventive dentistry procedures. Results Data from 108 Libyan dental graduates were analysed for this study, of which 64% of them were females and 42.1% of them passed their final year with grade: acceptable. The most acknowledged aspects of preventive dentistry were being useful and essential to the community (95.4 and 90.8%, respectively). The percentage of participants expressing a proficiency in providing oral hygiene instructions was the highest (95.4%). There were differences between study subgroups in their perceived competence of preventive dental practices by gender and academic performance (p?0.05). Conclusion This study highlighted that the currently implemented undergraduate education programme in Benghazi dental school does not provide dentists with the required attitude and skills to fulfil their role in providing preventive-oriented health services.

The importance of preventive dental visits from a young age: systematic review and current perspectives  

PubMed Central

Background Dental caries, the most common childhood chronic disease, disproportionately affects vulnerable parts of the population and confers substantial impacts to children, families, and health systems. Because efforts directed toward oral health promotion and disease prevention are fundamentally superior to dental rehabilitation secondary to disease development, early preventive dental visits (EPDVs) are widely advocated by professional and academic stakeholders. The aim of this comprehensive review was to critically review and summarize available evidence regarding the effectiveness of EPDVs in improving children’s oral health outcomes. Materials and methods A systematic literature search of the PubMed and Embase electronic databases was undertaken to identify peer-reviewed publications investigating the effectiveness of EPDVs on oral health outcomes, including clinical, behavioral, and cost end points up to October 30, 2013. Outcomes of the identified studies were abstracted and summarized independently by two investigators. Results Four manuscripts met the inclusion criteria and were included in the review. All studies were conducted in the US and employed a retrospective cohort study design using public insurance-claims data, whereas one study matched claims files with kindergarten state dental surveillance data. That study found no benefit of EPDVs in future clinically determined dental caries levels in kindergarten. The other three studies found mixed support for an association of EPDVs with subsequent more preventive and fewer nonpreventive visits and lower nonpreventive service-related expenditures. Selection bias and a problem-driven dental care-seeking pattern were frequently articulated themes in the reviewed studies. Conclusion The currently available evidence base supporting the effectiveness of EPDVs and the year 1 first dental visit recommendation is weak, and more research is warranted. The benefits of EPDVs before the age of 3 years are evident among children at high risk or with existing dental disease. However, EPDVs may be associated with reduced restorative dental care visits and related expenditures during the first years of life. PMID:24672258

Persistent pain and neurosensory disturbance after dental implant surgery: prevention and treatment.  

PubMed

Nerve trauma caused by dental implant placement is associated with altered sensation and chronic pain. Complete or partial loss of sensation is often reported by patients who have experienced nerve trauma during implant surgery. Some patients report persistent pain and neurosurgery disturbance long after the normal healing time has passed. In addition, neuropathic pain is reported after implant surgery. Practitioners who place dental implants must be familiar with the differential diagnosis, prevention, and management of neuropathic pain. This article provides insights into the prevention and management of neurosensory deficits and chronic persistent neuropathic pain and considerations for patient referral. PMID:25434563

A new curriculum framework for clinical prevention and population health, with a review of clinical caries prevention teaching in U.S. and Canadian dental schools.  

PubMed

To fulfill the Healthy People 2010 Objective 1.7, "Increase the proportion of . . . health professional training schools whose basic curriculum for health care providers includes the core competencies in health promotion and disease prevention," the Healthy People Curriculum Task Force has developed a curriculum framework for clinical prevention and population health for all the health professions. This framework has four components: 1) evidence base for practice; 2) clinical preventive services, including health promotion; 3) health systems and health policy; and 4) community aspects of practice. Within these four common components are nineteen domains, for which each health profession is identifying its own educational objectives. An inventory of knowledge and skills is being developed. A prerequisite to promoting change in the teaching of dental prevention and population oral health is to better understand the current status. Sixty-six of sixty-eight U.S. and Canadian dental schools provided input on the teaching of one important aspect of this wider topic--dental caries prevention--before a December 2002 Clinical Preventive Dentistry Leadership Conference in Cincinnati, OH. In clinical teaching, 68 percent of dental schools included caries risk assessment and also reevaluated preventive outcomes, but while 65 percent included remineralization procedures, only 38 percent specifically reevaluated this outcome. Faculty members have commonalities in attitudes about the advantages and problems in improving teaching in clinical prevention, yet dental schools act individually in curricular design and implementation. The conference introduced a method of conceptualizing change, so that dental schools might address organizational barriers in clinical curriculum development. Even with the new common curriculum framework, other barriers to improved dental prevention and population oral health exist: these include organizational change in dental schools, dental practices, and dental clinics; reimbursement issues and incentives; and lack of accepted and explicit standards in dental care.

Hair keratin mutations in tooth enamel increase dental decay risk.  

PubMed

Tooth enamel is the hardest substance in the human body and has a unique combination of hardness and fracture toughness that protects teeth from dental caries, the most common chronic disease worldwide. In addition to a high mineral content, tooth enamel comprises organic material that is important for mechanical performance and influences the initiation and progression of caries; however, the protein composition of tooth enamel has not been fully characterized. Here, we determined that epithelial hair keratins, which are crucial for maintaining the integrity of the sheaths that support the hair shaft, are expressed in the enamel organ and are essential organic components of mature enamel. Using genetic and intraoral examination data from 386 children and 706 adults, we found that individuals harboring known hair disorder-associated polymorphisms in the gene encoding keratin 75 (KRT75), KRT75(A161T) and KRT75(E337K), are prone to increased dental caries. Analysis of teeth from individuals carrying the KRT75(A161T) variant revealed an altered enamel structure and a marked reduction of enamel hardness, suggesting that a functional keratin network is required for the mechanical stability of tooth enamel. Taken together, our results identify a genetic locus that influences enamel structure and establish a connection between hair disorders and susceptibility to dental caries. PMID:25347471

Novel technologies for the prevention and treatment of dental caries: a patent survey  

PubMed Central

Importance of the field: Dental caries is one of the most common preventable childhood diseases; people are susceptible to this ailment throughout their lifetime. In the United States, 90% of late adolescents and young adults have dental caries, while 94% of all dentate adults had evidence of treated or untreated coronal caries. Dental caries is often not self-limiting and without proper care, caries can progress until the tooth is destroyed. Areas covered in this review: In this paper, the etiology of dental caries was briefly introduced. It was followed by a thorough review of patents and literatures on the recent development of various novel technologies for the prevention and treatment of dental caries. What the reader will gain: Recent advances in anti-plaque agents, including chemoprophylactic agents, antimicrobial peptides, vaccines, probiotics/replacement therapy and sugar substitutes, and remineralization agents including fluorides and casein phosphopeptides are analyzed. Take home massage: Both the discovery of new anti-caries agents and the development of dentotropic delivery systems will be the future focus of this research field. PMID:20230309

Laser dental decay prevention: does it have a future?  

NASA Astrophysics Data System (ADS)

Previous studies have recorded the reduction of caries-like lesions or demineralization in extracted human teeth that have been irradiated using CO2, Nd:YAG and Argon lasers, with CO2 or Argon showing up to 40 - 50% reduction. By adding a chemical inhibitor, such as DAC or fluoride to lasing procedures, the demineralization can be reduced 60 - 80%. Studies have demonstrated the laser safety for Argon and CO2 laser in these procedures. Clinical trials are being initiated to evaluate acid resistance of enamel exposed to laser radiation. This presentation will review prior results and present our current findings.

Role of estrogen related receptor beta (ESRRB) in DFN35B hearing impairment and dental decay  

PubMed Central

Background Congenital forms of hearing impairment can be caused by mutations in the estrogen related receptor beta (ESRRB) gene. Our initial linkage studies suggested the ESRRB locus is linked to high caries experience in humans. Methods We tested for association between the ESRRB locus and dental caries in 1,731 subjects, if ESRRB was expressed in whole saliva, if ESRRB was associated with the microhardness of the dental enamel, and if ESRRB was expressed during enamel development of mice. Results Two families with recessive ESRRB mutations and DFNB35 hearing impairment showed more extensive dental destruction by caries. Expression levels of ESRRB in whole saliva samples showed differences depending on sex and dental caries experience. Conclusions The common etiology of dental caries and hearing impairment provides a venue to assist in the identification of individuals at risk to either condition and provides options for the development of new caries prevention strategies, if the associated ESRRB genetic variants are correlated with efficacy.

Soft drinks have many potential health problems. The inherent acids and sugars have both acidogenic and cariogenic potential, resulting in dental caries and potential enamel erosion. In this report we present a 25-year-old man complaining with the severe worn-out of the front teeth during the past 3 years. He had a history of drinking cola for more than 7 years and had a poor oral hygiene. Severe decays were present in the incisors and the canines, while less severe lesions were noted on the premolars and the molars.

Iatrogenic injury to the pulp in dental procedures: aspects of pathogenesis, management and preventive measures.  

PubMed

This review calls attention to the fact that iatrogenic ('dentistogenic') injury to the dental pulp is not an insignificant problem in clinical dentistry. On a short-term basis pulpal inflammatory lesions and hypersensitive teeth are frequently associated with procedures that involve removal of the dental hard tissue structures. Although the pulp is likely to recover, reparative processes induced by the insult may impair pulpal function on a long-term basis. In this paper current concepts regarding pathogenic mechanisms associated with injuries induced in the pulp by restorative and periodontal treatment procedures are reviewed. Aspects of the management of accidental pulp exposures are also described as well as measures to prevent or reduce iatrogenic injuries to the pulp. PMID:2032743

First aid for dental trauma caused by sports activities: state of knowledge, treatment and prevention.  

PubMed

In view of the widespread lack of knowledge of first aid procedures in cases of dental trauma, this article describes the current state of knowledge and highlights the need for education of those likely to witness or be victims of dental trauma while practising sports. Dental and oral injuries, the commonest type of orofacial injuries, are often sustained by athletes playing contact sports; indeed, they represent the most frequent type of sporting injury. Studies of a large group of children and adults have shown that as many as 31% of all orofacial injuries are caused by sporting activities. Furthermore, current literature on the subject emphasizes that awareness of appropriate triage procedures following dental trauma is unsatisfactory. Delay in treatment is the single most influential factor affecting prognosis. What should we know and, more importantly, what should we do? Immediate replantation of an avulsed tooth is the best treatment option at the site of the accident. If replantation is impossible, milk is the preferred transport medium for the avulsed tooth. There is a general low level of awareness about the need for prompt triage of traumatic dental injuries sustained in sports, despite their relative frequency. When a cohort of Swiss basketball players was interviewed, only half were aware that an avulsed tooth could be replanted. Cheap, commercially available tooth storage devices containing an isotonic transport medium (so-called 'Save-a-Tooth boxes'), can maintain the viability of an avulsed tooth for up to 72 hours, prior to replantation. More readily available storage media such as milk, sterile saline or even saliva may be used, but knowledge of this information is rare among sports participants. For example, just 6.6% of the Swiss basketball players interviewed were aware of the 'Tooth Rescue box' products. Sporting organizations seem to offer very little information about sports-related risks or preventive strategies for orodental trauma. Having an attending dentist at sports events - amateur or professional - is clearly a luxury that is neither practical nor affordable. The solution must lie in extending the knowledge of management of orodental trauma beyond the dental profession. Educational posters, when displayed prominently in sports clubs, gym halls and dressing rooms of swimming pools, are a clear, accessible and low cost method of presenting the appropriate procedures to follow after orodental injury. When the potentially avoidable financial burden and discomfort of protracted restorative or cosmetic dentistry are taken into account, rarely can such significant morbidity be so easily prevented.

Dental plaque, preventive care, and tooth brushing associated with dental caries in primary teeth in schoolchildren ages 6–9 years of Leon, Nicaragua  

PubMed Central

Background Our study aimed to evaluate the effect of various risk indicators for dental caries on primary teeth of Nicaraguan children (from Leon, Nicaragua) ages 6 to 9, using the negative binomial regression model. Material/Methods A cross-sectional study was carried out to collect clinical, demographic, socioeconomic, and behavioral data from 794 schoolchildren ages 6 to 9 years, randomly selected from 25 schools in the city of León, Nicaragua. Clinical examinations for dental caries (dmft index) were performed by 2 trained and standardized examiners. Socio-demographic, socioeconomic, and behavioral data were self-reported using questionnaires. Multivariate negative binomial regression (NBR) analysis was used. Results Mean age was 7.49±1.12 years. Boys accounted for 50.1% of the sample. Mean dmft was 3.54±3.13 and caries prevalence (dmft >0) was 77.6%. In the NBR multivariate model (p<0.05), for each year of age, the expected mean dmft decreased by 7.5%. Brushing teeth at least once a day and having received preventive dental care in the last year before data collection were associated with declines in the expected mean dmft by 19.5% and 69.6%, respectively. Presence of dental plaque increased the expected mean dmft by 395.5%. Conclusions The proportion of students with caries in this sample was high. We found associations between dental caries in the primary dentition and dental plaque, brushing teeth at least once a day, and having received preventive dental care. To improve oral health, school programs and/or age-appropriate interventions need to be developed based on the specific profile of caries experience and the associated risk indicators. PMID:24247119

Design of the Prevention of Adult Caries Study (PACS): A randomized clinical trial assessing the effect of a chlorhexidine dental coating for the prevention of adult caries  

PubMed Central

Background Dental caries is one of the primary causes of tooth loss among adults. It is estimated to affect a majority of Americans aged 55 and older, with a disproportionately higher burden in disadvantaged populations. Although a number of treatments are currently in use for caries prevention in adults, evidence for their efficacy and effectiveness is limited. Methods/Design The Prevention of Adult Caries Study (PACS) is a multicenter, placebo-controlled, double-blind, randomized clinical trial of the efficacy of a chlorhexidine (10% w/v) dental coating in preventing adult caries. Participants (n = 983) were recruited from four different dental delivery systems serving four diverse communities, including one American Indian population, and were randomized to receive either chlorhexidine or a placebo treatment. The primary outcome is the net caries increment (including non-cavitated lesions) from baseline to 13 months of follow-up. A cost-effectiveness analysis also will be considered. Discussion This new dental treatment, if efficacious and approved for use by the Food and Drug Administration (FDA), would become a new in-office, anti-microbial agent for the prevention of adult caries in the United States.

Triclosan-loaded Tooth-binding Micelles for Prevention and Treatment of Dental Biofilm  

PubMed Central

The purpose of the present study was to develop tooth-binding micelle formulations and evaluate their ability to both inhibit initial biofilm formation as well as decrease the viability of preformed biofilm using an in vitro dental biofilm model. Alendronate (ALN, a bisphosphonate) was covalently attached to the ends of different Pluronic copolymers to confer tooth-binding ability to the micelles, and triclosan was used as a model drug. Based on different micelle preparation methods, Pluronic copolymers and ALN-terminated Pluronic copolymers were used to prepare triclosan-loaded tooth-binding micelles. The formulation was optimized for triclosan solubility, particle size, hydroxyapatite (HA) binding capacity and kinetics, and in vitro drug release behavior. In vitro biofilm treatment studies demonstrated that the triclosan-loaded tooth-binding micelles were able to inhibit initial biofilm growth of Streptococcus mutans UA159 by 6-log CFU/HA disc compared to the untreated control. These tooth-binding micelles were also capable of reducing the viability of preformed biofilm by 4-log CFU/HA disc compared to untreated control biofilm. In summary, triclosan-loaded tooth-binding micelles have been successfully developed and optimized in this study. These micelles demonstrated promising anti-biofilm capabilities that have the potential for use in the future treatment and prevention of dental diseases. PMID:20387099

Xylitol pediatric topical oral syrup to prevent dental caries: a double blind, randomized clinical trial of efficacy  

PubMed Central

Objective To evaluate the effectiveness of a xylitol pediatric topical oral syrup to reduce the incidence of dental caries of very young children. Design Randomized, double-blinded, controlled trial. Setting Communities in the Republic of the Marshall Islands. Participants 108 children aged 9 to 15 months were screened and 100 were enrolled. Intervention Children were randomized and parents administered topical oral xylitol syrup two times (Xyl-2X, two xylitol 4.00 g/dose + one sorbitol dose) or three times (Xyl-3X, three xylitol 2.67 g/dose) per day (total 8 g) or control (one xylitol 2.67 g/dose + two sorbitol dose). Outcome Measures The outcome end-point of the study was the number of decayed primary teeth. Results Ninety-four of 100 children (mean±SD age, 15.0±2.7 months at randomization) with at least one follow-up exam were included in the intent-to-treat analysis. The mean±SD follow-up period was 10.5±2.2 months. Nearly 52% of children in the control condition had tooth decay compared to 40.6% among Xyl-3X and 24.2% among Xyl-2X conditions. The mean±SD number of decayed teeth was 1.9±2.4 for control, 1.0±1.4 for Xyl-3X, and 0.6±1.1 for Xyl-2X condition. Compared to controls, there was significantly fewer decayed teeth in the Xyl-2X (relative risk [RR], 0.30; 95% confidence interval [CI] 0.13, 0.66; P=.003) and Xyl-3X (RR, 0.50; 95% CI 0.26, 0.96; P=0.037) conditions. There was no statistical difference between the two xylitol treatment conditions (P=0.22). Conclusion Oral xylitol syrup administered topically two or three times each day at a total dose of 8 g was effective in preventing Early Childhood Caries. PMID:19581542

Prevention of infective endocarditis: a review of the medical and dental literature.  

PubMed

This paper is a review of what is presently known about the cause and prevention of infective endocarditis. Systemic antibiotics alone are not always enough for an effective prevention of infective endocarditis. Non-streptococcus bacteria frequently found in the periodontal pocket are now reported as causing infective endocarditis; these bacteria are not uniformly susceptible to the antibiotics recommended for prophylaxis. Animal studies indicate that periodontal disease does increase the incidence of infective endocarditis and that the number of microbes entering the blood stream may not be as important in the production of infective endocarditis as other qualities, such as the microbe's ability to adhere. Antibiotics may affect the ability of a microorganism to adhere to tissues of the heart, but this association is yet unclear and may vary with the antibiotic and species of bacteria. Reduction of inflammation of the periodontal tissues is of the utmost importance in the prevention of infective endocarditis; however, mouthrinses have a very limited effect in a periodontal pocket of more than 3 mm in depth and irrigation of a periodontal pocket may create a dangerous bacteremia. Nevertheless, in addition to systemic antibiotics, local antimicrobial agents followed by routine dental treatment and maintenance show promise as an effective means for the prevention of infective endocarditis. Future research in the prevention of infective endocarditis should include placement of antimicrobials in the periodontal pocket and systemic agents that reduce platelet adhesion. The suggestions presented in this review are only recommendations for further research and are not to be construed as a substitute for the current guidelines. PMID:1920019

Alternatives to fluoride in the prevention and treatment of dental erosion.  

PubMed

In recent years, different agents have been discussed as potential alternatives to fluoride in the prevention of dental erosion. These agents are intended to form acid-resistant layers on the surface, to induce repair of eroded lesions by mineral precipitation or to prevent the enzymatic degradation of demineralised collagen. The application of adhesives and/or fissure sealants is considered to be an effective alternative to fluoride, but requires professional application and, depending on the product used, a re-sealing of the surface every several months. Studies testing film-forming products, such as polymers, have suggested the potential effectiveness of some of these approaches, such as chitosan, although further studies are needed to confirm the effectiveness of this approach. Other studies have demonstrated that products designed to deliver calcium and/or phosphate have not been successful at providing a significant anti-erosive effect. In advanced erosive lesions, the demineralised collagenous dentine matrix can be degraded by host enzymes such as matrix metalloproteinases (MMPs). As well as fluorides, epigallocatechin gallate and chlorhexidine have been identified as effective MMP inhibitors, with the potential to reduce the progression of dentine erosion. While fluoride compounds have been shown to have an anti-erosive potential, particularly those containing tin, alternative approaches that provide even greater protective capacity still need to be developed and proven to be effective.

Effect of honey in preventing gingivitis and dental caries in patients undergoing orthodontic treatment  

PubMed Central

Objectives This study was conducted to investigate the following: (1) the effects of chewing honey on plaque formation in orthodontic patients, (2) the effect of chewing honey on dental plaque bacterial counts, (3) determine if honey possesses antibacterial effects on bacteria recovered from plaques. Methods Female orthodontic patients (n = 20, 12–18 years of age) participated in this randomized controlled study. The effects of honey were compared to treatment with either 10% sucrose or 10% sorbitol that served as positive and negative controls, respectively. The pH of plaque was measured using a digital pH meter prior to baseline and at 2, 5, 10, 20, and 30 min after chewing honey or rinsing with control solutions and the numbers of Streptococcus mutans, Lactobacilli, and Prophymonas gingivalis in respective plaques were determined. The antibacterial activity of honey was tested against commonly used antibiotics using the disk diffusion method. Results Significant differences in pH were observed in the honey and sucrose groups compared to the pH observed in the sorbitol group (p ? 0.001). The maximum pH drop occurred at 5 min in both the honey and sucrose groups; however the pH in the honey group rapidly recovered 10–20 min after exposure and did not drop below the critical decalcification pH of 5.5. On the other hand, the pH following sucrose exposure fell <5.5 and was associated with a 30 min recovery time. The pH observed for the sorbitol group did not change over time. Bacterial counts were significantly reduced in the honey group compared to the other treatment groups (p ? 0.001) and honey significantly inhibited the growth of all studied strains compared to inhibition observed with antibiotics (p ? 0.001). Conclusions Honey can be used as an alternative to traditional remedies for the prevention of dental caries and gingivitis following orthodontic treatment. PMID:25057231

Application of chimeric glucanase comprising mutanase and dextranase for prevention of dental biofilm formation.  

PubMed

Water-insoluble glucan (WIG) produced by mutans streptococci, which is one of important cariogenic pathogens, plays an important role in the formation of dental biofilm and adhesion of biofilm to tooth surfaces. Glucanohydrolases, such as mutanase (?-1,3-glucanase) and dextranase (?-1,6-glucanase) are able to hydrolyze WIG. The purposes of this study were to construct bi-functional chimeric glucanase, composed of mutanase and dextranase, and to examine the effects of chimeric glucanase on the formation and decomposition of biofilm. The mutanase gene from Paenibacillus humicus NA1123 and the dextranase gene from Streptococcus mutans ATCC 25175 were cloned and ligated into a pE-SUMOstar Amp plasmid vector. The his-tagged fusion chimeric glucanase was expressed in Escherichia coli BL21 (DE3) and partially purified. The effects of chimeric glucanase on the formation and decomposition of biofilm formed on a glass surface by Streptococcus sobrinus 6715 glucosyltransferases were examined. This biofilm was fractionated into the firm-adherent, loose-adherent and non-adherent WIG fractions. Amounts of WIG in each fraction were determined by the phenol-sulfuric acid method, and reducing sugars were quantified by the Somogyi-Nelson method. Chimeric glucanase reduced the formation of the total amount of WIG in a dose-dependent manner, and significant reductions of WIG in the adherent fraction were observed. Moreover, we found that the chimeric glucanase was able to decompose biofilm; the chimeric glucanase was 4.1 times more effective at glucan inhibition of biofilm formation than a mixture of dextranase and mutanase. These results suggest that the chimeric glucanase is useful for the prevention of dental biofilm formation. PMID:25411090

Dental calculus: recent insights into occurrence, formation, prevention, removal and oral health effects of supragingival and subgingival deposits.  

PubMed

Dental calculus, both supra- and subgingival occurs in the majority of adults worldwide. Dental calculus is calcified dental plaque, composed primarily of calcium phosphate mineral salts deposited between and within remnants of formerly viable microorganisms. A viable dental plaque covers mineralized calculus deposits. Levels of calculus and location of formation are population specific and are affected by oral hygiene habits, access to professional care, diet, age, ethnic origin, time since last dental cleaning, systemic disease and the use of prescription medications. In populations that practice regular oral hygiene and with access to regular professional care, supragingival dental calculus formation is restricted to tooth surfaces adjacent to the salivary ducts. Levels of supragingival calculus in these populations is minor and the calculus has little if any impact on oral-health. Subgingival calculus formation in these populations occurs coincident with periodontal disease (although the calculus itself appears to have little impact on attachment loss), the latter being correlated with dental plaque. In populations that do not practice regular hygiene and that do not have access to professional care, supragingival calculus occurs throughout the dentition and the extent of calculus formation can be extreme. In these populations, supragingival calculus is associated with the promotion of gingival recession. Subgingival calculus, in "low hygiene" populations, is extensive and is directly correlated with enhanced periodontal attachment loss. Despite extensive research, a complete understanding of the etiologic significance of subgingival calculus to periodontal disease remains elusive, due to inability to clearly differentiate effects of calculus versus "plaque on calculus". As a result, we are not entirely sure whether subgingival calculus is the cause or result of periodontal inflammation. Research suggests that subgingival calculus, at a minimum, may expand the radius of plaque induced periodontal injury. Removal of subgingival plaque and calculus remains the cornerstone of periodontal therapy. Calculus formation is the result of petrification of dental plaque biofilm, with mineral ions provided by bathing saliva or crevicular fluids. Supragingival calculus formation can be controlled by chemical mineralization inhibitors, applied in toothpastes or mouthrinses. These agents act to delay plaque calcification, keeping deposits in an amorphous non-hardened state to facilitate removal with regular hygiene. Clinical efficacy for these agents is typically assessed as the reduction in tartar area coverage on the teeth between dental cleaning. Research shows that topically applied mineralization inhibitors can also influence adhesion and hardness of calculus deposits on the tooth surface, facilitating removal. Future research in calculus may include the development of improved supragingival tartar control formulations, the development of treatments for the prevention of subgingival calculus formation, the development of improved methods for root detoxification and debridement and the development and application of sensitive diagnostic methods to assess subgingival debridement efficacy.

Effects of common dental materials used in preventive or operative dentistry on dentin permeability and remineralization.  

PubMed

The aim of this study was to evaluate the dentin remineralization induced by bioactive substances contained in common dental materials used in preventive and operative dentistry. Several materials were applied on human dentin segments. Dentin permeability was quantified using a fluid filtration system working at 20 cm H(2)O. Micro-Raman, SEM-EDX, and microhardness calculation were used to evaluate changes in the mineralization of dentin. Dentin treated with the prophylactic materials showed different dentin permeability values, in particular subsequent to immersion in remineralizing solutions (RSS). The bioactive glass (Sylc) was the only substance able to reduce dentin permeability after immersion in remineralizing solution and to show hydroxyapatite precipitation as a sign of dentin remineralization. The reduction in dentin permeability obtained after the application of the other prophylactic materials used in this study was due to the presence of the remnant material in the dentinal tubules, with no remineralization effect after storage in remineralizing solution. In conclusion, the results indicated that bioactive glass prophy powder may induce immediate remineralization of dentin. PMID:21777102

Health Insurance, Socio-Economic Position and Racial Disparities in Preventive Dental Visits in South Africa  

PubMed Central

This study sought to determine the contributions of socio-economic position and health insurance enrollment in explaining racial disparities in preventive dental visits (PDVs) among South Africans. Data on the dentate adult population participating in the last South African Demographic and Health Survey conducted during 2003–2004 (n = 6,312) was used. Main outcome measure: Reporting making routine yearly PDVs as a preventive measure. Education, material wealth index and nutritional status indicated socio-economic position. Multi-level logistic regression analysis was conducted to determine the predictors of PDVs. A variant of Blinder-Oaxaca decomposition analysis was also conducted. Health insurance coverage was most common among Whites (70%) and least common among black Africans (10.1%) in South Africa. Similarly, a yearly PDV was most frequently reported by Whites (27.8%) and least frequently reported among black Africans (3.1%). Lower education and lower material wealth were associated with lower odds of making PDVs. There was significant interaction between location (urban/rural) and education (p = 0.010). The racial and socio-economic differences in PDVs observed in urban areas were not observed in rural areas. In the general dentate population, having health insurance significantly increased the odds of making PDVs (OR = 4.32; 3.04–6.14) and accounted for 40.3% of the White/non-White gap in the probability of making PDVs. Overall, socio-economic position and health insurance enrollments together accounted for 55.9% (95% CI = 44.9–67.8) of the White/non-White gap in PDVs. Interventions directed at improving both socio-economic position and insurance coverage of non-White South Africans are likely to significantly reduce racial disparities in PDVs. PMID:23282482

Prevention of dental damage and improvement of difficult intubation using a paraglossal technique with a straight Miller blade.  

PubMed

Patients with diseased teeth, or those who are difficult to intubate, have a higher risk of dental injury during laryngoscopy. We report 3 cases of smooth endotracheal intubation using a paraglossal technique with a straight Miller blade in patients with poor dentition. Three patients with poor dentition were scheduled to undergo surgery under general anesthesia. All patients presented with extremely loose upper central incisors and had lost the other right upper teeth, while micrognathia and prominent, loose upper incisors were noted in 1 case. We elected to use a straight Miller blade using a paraglossal approach. A nasopharyngeal airway was inserted after induction of general anesthesia to facilitate mask ventilation and prevent air leakage from the mask. The Miller blade was then inserted from the right corner of the mouth, avoiding contact with the vulnerable incisors, and advanced along the groove between the tongue and tonsil. The endotracheal tube was subsequently smoothly inserted after obtaining a grade 1 Cormack and Lehane view without dental trauma in all 3 cases. Direct laryngoscopy using the paraglossal straight blade technique avoids dental damage in patients with mobile upper incisors and no right maxillary molars. It is a practical alternative method that differs from the traditional Macintosh laryngoscope in patients with a high risk of dental injury during the procedure. This technique, which provides an improved view of the larynx, might also be helpful with patients in whom intubation is difficult. PMID:21051035

[Empathy and prevention: from the child's viewpoint. Comments on a school diary developed from dental prophylaxis messages].  

PubMed

The paper presents, explains and comments on the theoretical, practical and applied aspects of a collaborative enterprise between Health Services and a primary school in the context of a dental hygiene and preventive project organised by the USSL no. 19 in Mediobrenta. The enterprise in question concerned the experimental writing, by the children themselves, of a school diary, based on messages regarding dental health and hygiene formulated by the Odontostomatological Service in line with learning processes and communication models used during infancy. The experiment formed part of the general active approach of modern psychological pedagogy, and proved particularly efficacious in introducing medical concepts to an infantile population which would otherwise have met with much greater resistance.

Use of Preventive Dental Care Among Medicaid-Enrolled, School-Aged US Children in Immigrant and Nonimmigrant Families: Trends in Pennsylvania From 2005 Through 2010  

PubMed Central

Objectives. We describe trends in receipt of preventive dental care among Medicaid-enrolled children in Pennsylvania between 2005 and 2010, comparing the US children of immigrants with their co-ethnic peers in nonimmigrant families. Methods. We analyzed Pennsylvania Medicaid claims, birth records, and census data for children born in Pennsylvania and enrolled in Medicaid for 10 or more months during any of the calendar years assessed. Results. Receipt of preventive dental care was more likely among Latino children in immigrant families than among their peers in nonimmigrant families; also, it was more likely among White children in immigrant families than among their peers in nonimmigrant families. Rates of preventive dental care use among African American and Asian children in immigrant and nonimmigrant families were comparable. From 2005 to 2010, the percentage of Latino children in nonimmigrant families who received preventive dental care increased from 33% to 61%. Changes in other groups were significant but less dramatic. Conclusions. Receipt of preventive dental care has increased among Medicaid-enrolled children in Pennsylvania, with marked gains among Latino children. Within each racial/ethnic group, the children of immigrants were either more likely than or equally likely as children in nonimmigrant families to receive care. PMID:25322290

Mucoadhesive electrospun chitosan-based nanofibre mats for dental caries prevention.  

PubMed

The mucoadhesive electrospun nanofibre mats were developed using chitosan (CS) and thiolated chitosan (CS-SH) as mucoadhesive polymers. Garcinia mangostana (GM) extract was incorporated into nanofibre mats. The antibacterial activity in the single and combined agents was evaluated against dental caries pathogens. The morphology of mats was observed using SEM. The mats were evaluated for GM extract amount, mucoadhesion, in vitro release, antibacterial activity and cytotoxicity. The mucoadhesion and antibacterial activity were determined in healthy human volunteers. The prepared mats were in nanoscale with good physical and mucoadhesive properties. The CS-SH caused the higher mucoadhesion. All mats rapidly released active substances, which had the synergistic antibacterial activity. In addition, the reduction of bacteria and good mucoadhesion in the oral cavity occurred without cytotoxicity. The results suggest that mats have the potential to be mucoadhesive dosage forms to maintain oral hygiene by reducing the bacterial growth that causes the dental caries. PMID:25498719

Progress has been made in reducing dental caries and edentulism in older adults, but disparities continue to exist related to race, ethnicity, socioeconomic level, and sex. Lack of training in treating medically complex patients, economic factors including absence of coverage for oral health services in Medicare and as a required service for adults in Medicaid, and attitudinal issues on the part of patients, caregivers, and providers contribute to barriers to care for older adults. In addition to the impact of oral health on overall health, oral health impacts quality of life and social and employment opportunities. PMID:25201540

Near-infrared image-guided laser ablation of dental decay  

PubMed Central

Image-guided laser ablation systems are now feasible for dentistry with the recent development of nondestructive high-contrast imaging modalities such as near-IR (NIR) imaging and optical coherence tomography (OCT) that are capable of discriminating between sound and demineralized dental enamel at the early stages of development. Our objective is to demonstrate that images of demineralized tooth surfaces have sufficient contrast to be used to guide a CO2 laser for the selective removal of natural and artificial caries lesions. NIR imaging and polarization-sensitive optical coherence tomography (PS-OCT) operating at 1310-nm are used to acquire images of natural lesions on extracted human teeth and highly patterned artificial lesions produced on bovine enamel. NIR and PS-OCT images are analyzed and converted to binary maps designating the areas on the samples to be removed by a CO2 laser to selectively remove the lesions. Postablation NIR and PS-OCT images confirmed preferential removal of demineralized areas with minimal damage to sound enamel areas. These promising results suggest that NIR and PS-OCT imaging systems can be integrated with a CO2 laser ablation system for the selective removal of dental caries. PMID:19895146

Effect of pretreatment with an Er:YAG laser and fluoride on the prevention of dental enamel erosion.  

PubMed

The aim of this study was to evaluate the effect of the Er:YAG laser and its association with fluoride (1.23 % acidulate phosphate fluoride gel) on the prevention of enamel erosion. Sixty specimens were obtained from bovine enamel (4?×?4 mm), which were ground flat, polished, and randomly divided into five groups according to the preventive treatments: control-fluoride application; L-Er:YAG laser; L+F-laser + fluoride; F+L-fluoride + laser; L/F-laser/fluoride simultaneously. Half of the enamel surface was covered with nail varnish (control area), and the other half was pretreated with one of the preventive strategies to subsequently be submitted to erosive challenge. When the laser was applied, it was irradiated for 10 s with a focal length of 4 mm and 60 mJ/2Hz. Fluoride gel was applied for 4 min. Each specimen was individually exposed to regular Coca-Cola® for 1 min, four times/day, for 5 days. Wear analysis was performed with a profilometer, and demineralization was assessed with an optical microscope. Data were analyzed using the Kruskal-Wallis test (wear)/Dunn test and ANOVA/Fisher's exact tests. The group L/F was similar to control group. The other groups showed higher wear, which did not present differences among them. In the demineralization assessment, the groups F+L and L/F showed lower demineralization in relation to the other groups. It can be concluded that none preventive method was able to inhibit dental wear. The treatments L/F and F+L showed lower enamel demineralization. PMID:24149579

Although CO2 laser irradiation can decrease enamel demineralisation, it has still not been clarified which laser wavelength and which irradiation conditions represent the optimum parameters for application as preventive treatment. The aim of the present explorative study was to find low-fluence CO2 laser (? = 10.6 ?m) parameters resulting in a maximum caries-preventive effect with the least thermal damage. Different

Dental care resistance prevention and antibiotic prescribing modification—the cluster-randomised controlled DREAM trial  

PubMed Central

Background Bacterial resistance development is one of the most urgent problems in healthcare worldwide. In Europe, dentistry accounts for a comparatively high amount of antibiotic prescriptions. In light of increasing levels of bacterial resistance, this development is alarming. So far, very few interventional studies have been performed, and further research is urgently needed. By means of a complex educational intervention, the DREAM trial aims at optimising antibiotic prescribing behaviour of general dentists in Germany. Method This is a cluster-randomised controlled trial, where each cluster consists of one dental practice and all of its patients in a defined period. Participants are general dentists practicing in the German region of Mecklenburg-Western Pomerania. Randomisation takes place after baseline data collection (6 months) and will be stratified by the antibiotic prescribing rates of the participating dental practices. Dentists randomised into the intervention group will participate in a complex small group educational seminar that aims at: increasing knowledge on bacterial resistance, pharmacology, and prophylaxis of infectious endocarditis; increasing awareness of dentist-patient communication using video-taped vignettes of dentist-patient communication on antibiotic treatment; improving collaboration between general dentists, general practitioners, and practice-based cardiologists on the necessity of antibiotic prophylaxis; enhancing awareness of the dentists’ own prescribing habits by providing antibiotic prescribing feedback; and increasing patient knowledge on antibiotic treatment by providing patient-centred information material on antibiotic prophylaxis of endocarditis. The dentists randomised into the control group will not receive any educational programme and provide care as usual. Primary outcome is the overall antibiotic prescribing rate measured at T1 (period of six months after intervention). In a subgroup of adult patients affected by odontogenic infections, microbiological analyses for antibiotic resistance of oral streptococci are performed. Discussion Major aim of the study is to improve the process of decision making with regard to antibiotic prescribing. The approach is simple to implement and might be used rapidly in graduate and post-graduate medical education. We expect the results of this trial to have a major impact on antibiotic prescription strategies and practices in Germany. Trial registration Current Controlled Trials ISRCTN09576376 PMID:24559212

Bioinspired amphiphilic phosphate block copolymers as non-fluoride materials to prevent dental erosion.  

PubMed

Inspired by the fact that certain natural proteins, e.g. casein phosphopeptide or amelogenin, are able to prevent tooth erosion (mineral loss) and to enhance tooth remineralization, a synthetic amphiphilic diblock copolymer, containing a hydrophilic methacryloyloxyethyl phosphate block (MOEP) and a hydrophobic methyl methacrylate block (MMA), was designed as a novel non-fluoride agent to prevent tooth erosion under acidic conditions. The structure of the polymer, synthesized by reversible addition-fragment transfer (RAFT) polymerization, was confirmed by gel permeation chromatography (GPC), Fourier transform infrared spectroscopy (FTIR), and nuclear magnetic resonance spectroscopy (NMR). While the hydrophilic PMOEP block within the amphiphilic block copolymer strongly binds to the enamel surface, the PMMA block forms a hydrophobic shell to prevent acid attack on tooth enamel, thus preventing/reducing acid erosion. The polymer treatment not only effectively decreased the mineral loss of hydroxyapatite (HAP) by 36-46% compared to the untreated control, but also protected the surface morphology of the enamel specimen following exposure to acid. Additionally, experimental results confirmed that low pH values and high polymer concentrations facilitate polymer binding. Thus, the preliminary data suggests that this new amphiphilic diblock copolymer has the potential to be used as a non-fluoride ingredient for mouth-rinse or toothpaste to prevent/reduce tooth erosion.

[Preventive and remineralization effect over incipient lesions of caries decay by phosphopeptide-amorphous calcium phosphate].  

PubMed

INTRODUCTION. Dental caries continues to affect a large percentage of Mexican children and currently advises that if diagnosed at an early stage can be reversed with minimally invasive treatments. The casein phosphopeptide amorphous calcium phosphate known as CPP-ACP is a phosphoprotein capable of releasing calcium and phosphate ions in the oral environment promoting remineralization. OBJECTIVE. To evaluate the effect of CPP-ACP with fluoride added in a scholar preventive program. MATERIAL AND METHODS. A cuasi- experimental study was conducted in 104 schools of six years old. The children were classified into three groups and received six months biweekly applications of different treatments: casein phosphopeptide amorphous calcium phosphate added fluoride (CPP-ACPF), sodium fluoride (NaF) and a control group. Clinical evaluation was performed with the laser fluorescence technique (Diagnodent model 2095). 1340 teeth were included: 294 teeth with incipient lesions and 1,046 healthy teeth. Statistical tests of ?2 y Mc Nemar were used. RESULTS. In the group that received the application of CPP-ACPF, 38% of incipient carious lesions were remineralizing compared with 21% in the group receiving the NaF (p < 0.001) and 15% in the control group (p < 0.0001) The percentage of teeth free of caries were preserved in the therapy group phosphoprotein was the biggest. This group also showed the lower proportion of deep carious lesion development (p < 0.0001). CONCLUSION. The application biweekly for six months of CPP-ACPF showed a protective and remineralizing effect on incipient carious lesions. His action was better than the application of NaF. However, to reduce the impact from dental caries in schoolchildren is important to have a comprehensive preventive approach that includes promoting self-care, as well as the application of sealants.

Chemico-therapeutic approach to prevention of dental caries. [using stannous fluoride gel  

NASA Technical Reports Server (NTRS)

The program of chemical preventive dentistry is based primarily upon the development of a procedure for stabilizing stannous fluoride in solution by forcing it into glycerin. New topical fluoride treatment concentrates, fluoride containing gels and prophylaxis pastes, as well as a completely stable stannous fluoride dentifrice are made possible by the development of a rather complicated heat application method to force stannous fluoride into solution in glycerin. That the stannous fluoride is clinically effective in such a preparation is demonstrated briefly on orthodontic patients.

IQuaD dental trial; improving the quality of dentistry: a multicentre randomised controlled trial comparing oral hygiene advice and periodontal instrumentation for the prevention and management of periodontal disease in dentate adults attending dental primary care  

PubMed Central

Background Periodontal disease is the most common oral disease affecting adults, and although it is largely preventable it remains the major cause of poor oral health worldwide. Accumulation of microbial dental plaque is the primary aetiological factor for both periodontal disease and caries. Effective self-care (tooth brushing and interdental aids) for plaque control and removal of risk factors such as calculus, which can only be removed by periodontal instrumentation (PI), are considered necessary to prevent and treat periodontal disease thereby maintaining periodontal health. Despite evidence of an association between sustained, good oral hygiene and a low incidence of periodontal disease and caries in adults there is a lack of strong and reliable evidence to inform clinicians of the relative effectiveness (if any) of different types of Oral Hygiene Advice (OHA). The evidence to inform clinicians of the effectiveness and optimal frequency of PI is also mixed. There is therefore an urgent need to assess the relative effectiveness of OHA and PI in a robust, sufficiently powered randomised controlled trial (RCT) in primary dental care. Methods/Design This is a 5 year multi-centre, randomised, open trial with blinded outcome evaluation based in dental primary care in Scotland and the North East of England. Practitioners will recruit 1860 adult patients, with periodontal health, gingivitis or moderate periodontitis (Basic Periodontal Examination Score 0–3). Dental practices will be cluster randomised to provide routine OHA or Personalised OHA. To test the effects of PI each individual patient participant will be randomised to one of three groups: no PI, 6 monthly PI (current practice), or 12 monthly PI. Baseline measures and outcome data (during a three year follow-up) will be assessed through clinical examination, patient questionnaires and NHS databases. The primary outcome measures at 3 year follow up are gingival inflammation/bleeding on probing at the gingival margin; oral hygiene self-efficacy and net benefits. Discussion IQuaD will provide evidence for the most clinically-effective and cost-effective approach to managing periodontal disease in dentate adults in Primary Care. This will support general dental practitioners and patients in treatment decision making. Trial registration Protocol ID: ISRCTN56465715 PMID:24160246

Epidemiology of dental caries in children in the United Arab Emirates.  

PubMed

Dental caries has a significant impact on the general health and development of children. Understanding caries epidemiology is an essential task for the United Arab Emirates (UAE) policymakers to evaluate preventive programmes and to improve oral health. The purpose of this review is to collect and summarise all data available in the published literature on the epidemiology of dental caries in the UAE in children aged under 13 years. This will provide dental health planners with a comprehensive data summary, which will help in the planning for and evaluation of dental caries prevention programmes. Data were collected from the various published studies in PubMed, Academic Search Complete, Google, and the reference lists in relevant articles. Four keywords were used in the search: 'dental caries,' 'epidemiology,' 'prevalence,' and 'UAE'. All studies conducted in the UAE in general or any single emirate that sheds light on the prevalence of dental caries of children under 13 years were included in this literature review. Studies on early childhood caries and factors associated with dental caries were also included. The review comprises 11 published surveys of childhood caries in UAE. The earliest study was published in 1991 and the most recent was published in 2011. The range of decayed, missing and filled primary teeth (dmft) in UAE children (age between 4 years and 6 years) was 5.1-8.4. For the 12-year-old group the decayed missing and filled permanent teeth (DMFT) ranged from 1.6 to 3.24. Baseline data on oral health and a good understanding of dental caries determinants are necessary for setting appropriate goals and planning for preventive oral health programmes. The current data available on the dmft and DMFT indicate that childhood dental caries is still a serious dental public health problem in the UAE that warrants immediate attention by the government and policy makers.

Dental onlay bridge-like prosthesis in three koalas (Phascolarctos cinereus): the use of Premise trimodal composite to prevent interproximal Eucalyptus spp. retention and infection.  

PubMed

Three koalas (Phascolarctos cinereus) presented with moderate to severe interproximal space accumulation with Eucalyptus spp. at the San Diego Zoo. Premise trimodal composite was used to create dental onlay bridge-like prostheses to eliminate open, enlarged interproximal spaces. The prostheses prevented further leaf material accumulation within the interproximal spaces and consequently reduced periodontal disease. Aesthetically, the prosthesis replicates normal tooth coloration and appearance and wears at a similar rate to surrounding teeth. Prosthetic repair or replacement may be required, so periodic examination every 3-6 mo is recommended. PMID:25000719

Tranexamic acid mouthwash--a prospective randomized study of a 2-day regimen vs 5-day regimen to prevent postoperative bleeding in anticoagulated patients requiring dental extractions.  

PubMed

This prospective randomized study analyses the use of a prescribed 4.8% tranexamic acid post-operative mouthwash over 2 days vs 5 days to prevent bleeding in patients taking warfarin who require dental extractions. Eighty-five patients therapeutically anticoagulated with warfarin for various conditions, ranging in age from 21 to 86 years and requiring dental extractions, were randomly divided into two groups. Group A postoperatively received a 4.8% tranexamic acid mouthwash to be used over a 2-day period. Group B received the same mouthwash and instructions postoperatively, to be taken over 5 days. All procedures were performed on an ambulatory basis under local anaesthetic by the same surgeon. Patients were reviewed 1, 3, and 7 days postoperatively to assess bleeding. Eighty-two of the 85 patients encountered no postoperative problems. Two patients in group A and one in group B had minor postoperative bleeds that required minor ambulatory intervention to control. This study shows that a 2-day postoperative course of a 4.8% tranexamic acid mouthwash is as equally effective as a 5-day course in controlling haemostasis post-dental extractions in patient's anticoagulated with warfarin.

Review of Spaceflight Dental Emergencies  

NASA Technical Reports Server (NTRS)

All exploration class missions--extending beyond earth's orbit--differ from existing orbital missions by being of longer duration and often not having a means of evacuation. If an exploration mission extends beyond a year, then there will be a greater lapse since the crewmembers last terrestrial dental exams, which routinely occur each year. This increased time since professional dental care could increase the chance of a dental emergency such as intractable pain, dental decay requiring a temporary filling, crown replacement, exposed pulp, abscess, tooth avulsion, or toothache. Additionally, any dental emergency will have to be treated in-flight with available resources and personnel who may not have extensive training in dental care. Thus, dental emergencies are an important risk to assess in preparation for exploration missions.

A phase II clinical trial of a dental health education program delivered by aboriginal health workers to prevent early childhood caries  

PubMed Central

Background Early Childhood Caries (ECC) is a widespread problem in Australian Aboriginal communities causing severe pain and sepsis. In addition dental services are difficult to access for many Aboriginal children and trying to obtain care can be stressful for the parents. The control of dental caries has been identified as a key indictor in the reduction of Indigenous disadvantage. Thus, there is a need for new approaches to prevent ECC, which reflect the cultural norms of Aboriginal communities. Methods/Design This is a Phase II single arm trial designed to gather information on the effectiveness of a dental health education program for Aboriginal children aged 6?months, followed over 2?years. The program will deliver advice from Aboriginal Health Workers on tooth brushing, diet and the use of fluoride toothpaste to Aboriginal families. Six waves of data collection will be conducted to enable estimates of change in parental knowledge and their views on the acceptability of the program. The Aboriginal Health Workers will also be interviewed to record their views on the acceptability and program feasibility. Clinical data on the child participants will be recorded when they are 30?months old and compared with a reference population of similar children when the study began. Latent variable modeling will be used to interpret the intervention effects on disease outcome. Discussion The research project will identify barriers to the implementation of a family centered Aboriginal oral health strategy, as well as the development of evidence to assist in the planning of a Phase III cluster randomized study.

A three-year randomized controlled trial in 6-year-old children on caries-preventive strategies in a general dental practice in the Netherlands.  

PubMed

A parallel-randomized controlled trial on caries-preventive strategies was conducted in a general dental practice with a mixed socioeconomic background patient population. The aim of this study was to test the hypothesis that, compared to regular care consisting of check-ups twice a year with professional fluoride applications and pit and fissure sealants in all permanent molars, a larger caries-preventive effect can be achieved by following a non-operative caries treatment and prevention (NOCTP) strategy or by following, in addition to regular care, an increased number of professional topical fluoride applications (IPFA). A total of 230 children (6.0 years ± 3 months of age) were randomly assigned to the two experimental groups or the control group. After 3 years, 179 participants remained in the study (54 NOCTP, 62 IPFA and 63 control). The children were examined at baseline and at 3 years by the same experienced examiner, who was blinded for the allocation of the children. Caries was scored clinically at the D3 level. Per protocol analysis revealed a mean DMFS increment after 3 years of 0.15 (95% CI -0.05 to 0.35) for NOCTP, 0.34 (95% CI 0.11 to 0.54) for IPFA and 0.47 (95% CI 0.26 to 0.68) for the control group. To account for missing data, multiple imputation was used, after which the mean DMFS increment was 0.11 (95% CI -0.05 to 0.27) for NOCTP, 0.29 (95% CI 0.11 to 0.46) for IPFA and 0.40 (95% CI 0.21 to 0.55) for the control group. Testing the differences with independent samples t test revealed a lower caries increment in the NOCTP group compared to the control group. ANCOVA was used to correct for differences in baseline dmfs, socioeconomic status and perceived dental hygiene burden. The ?DMFS effect size between the NOCTP and the control group dropped, losing statistical significance (p = 0.06). Although the results in this study are promising, it has yet to be established in a larger study whether NOCTP has the ability to be effective in regular dental practice with a mixed socioeconomic status population.

Survey and analysis of dental caries in students at a deaf-mute high school.  

PubMed

The present cross-sectional study was conducted to assess and compare the prevalence of dental caries of 229 deaf adolescents in a special senior high school and to identify factors related to dental caries, with a match group of 196 healthy adolescents in a normal senior high school, in Jiangsu province of East China. In this study the prevalence of dental caries was 55.9%, Decayed, Missing and Filled Teeth (DMFT) index in deaf students was 1.40±1.89; in healthy students was 13.8% and 1.36±1.72, respectively. Relatively lower proportion of awareness on dental health knowledge and lower proper practice of dental health behavior have been observed among deaf students compared with the control group. Multiple logistic regressions showed that the risk factors of dental caries in deaf students involved high frequency of consuming dessert and carbonated beverage. Poor oral health, lack of oral health knowledge and proper oral health practice could be found in deaf students. The dental treatment for the two groups was urgently needed. The dental health education concerning dietary behavior and prevention program to the deaf students and their parents should be reinforced; the supervision of oral health behavior for deaf and healthy students needs to be strengthened.

Dental care demand among children with dental insurance.  

PubMed Central

As the number of families with dental insurance and expenditures for dental care has increased over the past two decades, so has interest in determining cost-sharing effects on dental demand among insureds. Using a representative sample of Pennsylvania Blue Shield children insureds during 1980, we estimate cost-sharing effects on dental demand for basic (diagnostic, preventive, restorative, endodontic, and extraction services) and orthodontic care. Results indicate that cost-sharing has little influence on the probability of using any dental services and basic expenditures. However, the probability of using orthodontic services decreases 2.1 percent when the proportion of orthodontic expenditures paid by the parent increases 10 percent. By reducing the cost of care, cost-sharing reduces social class differences in dental demand common in unisured populations, likely producing public oral health benefits. PMID:2952622

Anti-Streptococcal activity of Brazilian Amazon Rain Forest plant extracts presents potential for preventive strategies against dental caries  

PubMed Central

Caries is a global public health problem, whose control requires the introduction of low-cost treatments, such as strong prevention strategies, minimally invasive techniques and chemical prevention agents. Nature plays an important role as a source of new antibacterial substances that can be used in the prevention of caries, and Brazil is the richest country in terms of biodiversity. Objective In this study, the disk diffusion method (DDM) was used to screen over 2,000 Brazilian Amazon plant extracts against Streptococcus mutans. Material and Methods Seventeen active plant extracts were identified and fractionated. Extracts and their fractions, obtained by liquid-liquid partition, were tested in the DDM assay and in the microdilution broth assay (MBA) to determine their minimal inhibitory concentrations (MICs) and minimal bactericidal concentrations (MBCs). The extracts were also subjected to antioxidant analysis by thin layer chromatography. Results EB271, obtained from Casearia spruceana, showed significant activity against the bacterium in the DDM assay (20.67±0.52 mm), as did EB1129, obtained from Psychotria sp. (Rubiaceae) (15.04±2.29 mm). EB1493, obtained from Ipomoea alba, was the only extract to show strong activity against Streptococcus mutans (0.08 mg/mLprevention strategies to treat caries.

Melatonin promotes hepatic differentiation of human dental pulp stem cells: clinical implications for the prevention of liver fibrosis.  

PubMed

Melatonin's effect on hepatic differentiation of stem cells remains unclear. The aim of this study was to investigate the action of melatonin on hepatic differentiation as well as its related signaling pathways of human dental pulp stem cells (hDPSCs) and to examine the therapeutic effects of a combination of melatonin and hDPSC transplantation on carbon tetrachloride (CCl4 )-induced liver fibrosis in mice. In vitro hepatic differentiation was assessed by periodic acid-Schiff (PAS) staining and mRNA expression for hepatocyte markers. Liver fibrosis model was established by injecting 0.5 mL/kg CCl4 followed by treatment with melatonin (5 mg/kg, twice a week) and hDPSCs. In vivo therapeutic effects were evaluated by histopathology and by means of liver function tests including measurement of alanine transaminase (ALT), aspartate transaminase (AST), and ammonia levels. Melatonin promoted hepatic differentiation based on mRNA expression of differentiation markers and PAS-stained glycogen-laden cells. In addition, melatonin increased bone morphogenic protein (BMP)-2 expression and Smad1/5/8 phosphorylation, which was blocked by the BMP antagonist noggin. Furthermore, melatonin activated p38, extracellular signal-regulated kinase (ERK), and nuclear factor-?B (NF-?B) in hDPSCs. Melatonin-induced hepatic differentiation was attenuated by inhibitors of BMP, p38, ERK, and NF-?B. Compared to treatment of CCl4 -injured mice with either melatonin or hDPSC transplantation alone, the combination of melatonin and hDPSC significantly suppressed liver fibrosis and restored ALT, AST, and ammonia levels. For the first time, this study demonstrates that melatonin promotes hepatic differentiation of hDPSCs by modulating the BMP, p38, ERK, and NF-?B pathway. Combined treatment of grafted hDPSCs and melatonin could be a viable approach for the treatment of liver cirrhosis. PMID:25431168

It is seen that when child reaches school age, accidents in the school environment in the form of falls, injuries due to contact sports, fights, abuse, etc. are very common and the main cause of traumatic dental injuries. Trauma may vary from minor enamel chipping or avulsion to extensive maxillofacial damage, more serious neck and brain injury, which may cause pain, disfigurement and mental agony, having immediate and long lasting effects. In such cases, a school teacher is in the right position to handle such an emergency and refer the child to the concerned dental surgeon or a pedodontist for further needful care. The main reason for delayed treatment of dental trauma is that people present at the site of injury are unaware of protocol of rapid and appropriate management leading to improper first aid treatment. The purpose of this study was to investigate the awareness of a group of school teachers from different schools about the prevention and emergency management of dental trauma in school children, by means of a questionnaire. Then educating them and reassessing their knowledge after a period of 3 months. Unfortunately, the public is unaware of the risks and does not have enough information about first aid emergency treatment or to avoid traumatic injuries. PMID:23404018

May caries-preventive fluoride regimes have an effect on dental erosive wear? An in situ study.  

PubMed

Abstract Objective. High and low concentration NaF regimes have shown caries protective properties, but the preventive effect against erosive/abrasive wear is unclear. Aim. To measure the inhibiting effect on enamel wear of low and highly concentrated sodium fluoride (NaF) toothpastes and a stannous (SnF2) fluoride gel in a single-blind, randomized in situ study, using a White Light Interferometer. Materials and methods. Sixteen human molars were each divided into four specimens, mounted on acrylic mouth appliances and worn by eight volunteers for 9 days. Experimental procedures were performed in the laboratory. The enamel specimens were brushed every day with fluoride-free toothpaste. Treatments; group 1: no fluoride treatment (control), group 2: SnF2 gel 2500 ppm F (5 min) every third day, group 3: NaF toothpaste 5000 ppm F 5 min every third day and 2 min the other days, group 4: NaF toothpaste 1450 ppm F (2 min) every day. In order to mimic gastric reflux/vomiting, the specimens were etched with 0.01 M HCl for 2 min twice a day. Results. The mean step height (µm) for the control specimens was -32.9 (SD = 6.8). The mean values for the other groups were -22.2 (SD = 8.4) (group 2), -30.8 (SD = 7.8) (group 3) and -31.4 (SD = 7.7) (group 4). Compared with the control, the SnF2 treated specimens showed significantly lower wear. The NaF toothpastes gave no significant protective effect. Conclusions. Application of SnF2 gel every third day gave protection against erosive-abrasive challenges. Daily application of both low concentration and high concentration NaF toothpaste provided no protection.

Dental manpower development in the Pacific: case study in the Republic of the Marshall Islands.  

PubMed

This case study reports the ongoing progress and results of a manpower development program to expand indigenous dental personnel at four levels in the Republic of the Marshall Islands. The program was designed to: 1) increase the number of Marshallese students who successfully complete dentistry training; 2) recruit and train a group of Marshallese high school graduates in dental assisting for service in new preventive outreach programs within the community; 3) enhance the dental training of health assistants providing primary medical care to outer islands away from the main population centers of Majuro and Ebeye; and 4) provide in-service training on tooth decay prevention for Head Start teachers. The program resulted in the training of one Marshallese dentist and two Marshallese dental therapist, 16 primary care health aides who received oral health training for work in the outer island dispensaries, and 200 Head Start and kindergarten teachers who completed in-service training in oral health. Additional expertise was shared with other United States Affiliated Pacific Islands (USAPI) to enhance the dental workforce throughout the Pacific. PMID:19772166

Utilization of dental care: An Indian outlook.  

PubMed

Oral health has a significant impact on the quality of life, appearance, and self-esteem of the people. Preventive dental visits help in the early detection and treatment of oral diseases. Dental care utilization can be defined as the percentage of the population who access dental services over a specified period of time. There are reports that dental patients only visit the dentist when in pain and never bother to return for follow-up in most cases. To improve oral health outcomes an adequate knowledge of the way the individuals use health services and the factors predictive of this behavior is essential. The interest in developing models explaining the utilization of dental services has increased; issues like dental anxiety, price, income, the distance a person had to travel to get care, and preference for preservation of teeth are treated as barriers in regular dental care. Published materials which pertain to the use of dental services by Indian population have been reviewed and analyzed in depth in the present study. Dental surgeons and dental health workers have to play an adequate role in facilitating public enlightenment that people may appreciate the need for regular dental care and make adequate and proper use of the available dental care facilities.

Tooth decay  

NSDL National Science Digital Library

Teeth can decay and break or fall out of the gum line if they become damaged. One way in which they can be damaged is if dental plaque builds up on teeth. Plaque consists mostly of bacteria, and these bacteria cause cavities to be made in teeth if they are not removed on a regular basis.

This article reports on a case of pneumoconiosis in a dental laboratory technician with a history of respiratory exposure to dental materials. Special attention is paid to the mineralogical analysis of the lung biopsy. The abundance of chromium, cobalt, and silica particles suggests that the dental technician's pneumoconiosis is the result of the combined effects of hard metal dusts and silica particles generated during finishing dental frameworks. Adequate technical protection such as a local ventilation system should be considered in dental laboratories to prevent respiratory exposure of dental technicians to airborne contaminants.

Kaposi's Sarcoma-Associated Herpesvirus G-Protein-Coupled Receptor Prevents AU-Rich-Element-Mediated mRNA Decay  

PubMed Central

During lytic Kaposi's sarcoma-associated herpesvirus (KSHV) infection, host gene expression is severely restricted by a process of global mRNA degradation known as host shutoff, which rededicates translational machinery to the expression of viral proteins. A subset of host mRNAs is spared from shutoff, and a number of these contain cis-acting AU-rich elements (AREs) in their 3? untranslated regions. AREs are found in labile mRNAs encoding cytokines, growth factors, and proto-oncogenes. Activation of the p38/MK2 signal transduction pathway reverses constitutive decay of ARE-mRNAs, resulting in increased protein production. The viral G-protein-coupled receptor (vGPCR) is thought to play an important role in promoting the secretion of angiogenic molecules from KSHV-infected cells during lytic replication, but to date it has not been clear how vGPCR circumvents host shutoff. Here, we demonstrate that vGPCR activates the p38/MK2 pathway and stabilizes ARE-mRNAs, augmenting the levels of their protein products. Using MK2-deficient cells, we demonstrate that MK2 is essential for maximal vGPCR-mediated ARE-mRNA stabilization. ARE-mRNAs are normally delivered to cytoplasmic ribonucleoprotein granules known as processing bodies (PBs) for translational silencing and decay. We demonstrate that PB formation is prevented during KSHV lytic replication or in response to vGPCR-mediated activation of RhoA subfamily GTPases. Together, these data show for the first time that vGPCR impacts gene expression at the posttranscriptional level, coordinating an attack on the host mRNA degradation machinery. By suppressing ARE-mRNA turnover, vGPCR may facilitate escape of certain target mRNAs from host shutoff and allow secretion of angiogenic factors from lytically infected cells. PMID:22696654

Dental caries experience and use of dental services among Brazilian prisoners.  

PubMed

This ross-sectional study involving 127 male prisoners evaluates the use of dental services and dental caries among Brazilian inmates. Data were collected by interview and clinical examination. Sociodemographic and sentencing information as well as use of dental services, self-reported dental morbidity, self-perception, and oral health impacts were investigated. The mean DMFT index value was 19.72. Of the components, the decayed component showed the highest mean value (11.06 ± 5.37). Statistically significant association was found between DMFTs with values from 22 to 32 and oral health satisfaction (p = 0.002), difficulty speaking (p = 0.024), shame of talking (p = 0.004) and smiling (p < 0.001). Regarding the use of dental services, 80% had their last dental appointment less than one year ago, with most visits occurring in prison (80%), with restorative treatment (32%), followed by dental pain (26.4%), being the main reasons for such appointments. Most prisoners used dental services provided by the prison. Although restorative treatment has been the main reason for the use of dental services, "decayed" and "missing" components contributed to the high mean DMFT index. PMID:25429680

Organo-Selenium-containing Dental Sealant Inhibits Bacterial Biofilm  

PubMed Central

Oral bacteria, including Streptococcus mutans and Streptococcus salivarius, contribute to tooth decay and plaque formation; therefore, it is essential to develop strategies to prevent dental caries and plaque formation. We recently showed that organo-selenium compounds covalently attached to different biomaterials inhibited bacterial biofilms. Our current study investigates the efficacy of an organo-selenium dental sealant (SeLECT-DefenseTM sealant) in inhibiting S. mutans and S. salivarius biofilm formation in vitro. The organo-selenium was synthesized and covalently attached to dental sealant material via standard polymer chemistry. By colony-forming unit (CFU) assay and confocal microscopy, SeLECT-DefenseTM sealant was found to completely inhibit the development of S. mutans and S. salivarius biofilms. To assess the durability of the anti-biofilm effect, we soaked the SeLECT-DefenseTM sealant in PBS for 2 mos at 37°C and found that the biofilm-inhibitory effect was not diminished after soaking. To determine if organo-selenium inhibits bacterial growth under the sealant, we placed SeLECT-Defense sealant over a lawn of S. mutans. In contrast to a control sealant, SeLECT-DefenseTM sealant completely inhibited the growth of S. mutans. These results suggest that the inhibitory effect of SeLECT-DefenseTM sealant against S. mutans and S. salivarius biofilms is very effective and durable. PMID:23475900

[Dental hygienists vital to sound oral health care].  

PubMed

The first Dutch Dental Hygiene School was opened in 1968. Educating dental hygiene professionals with preventive qualifications was a well-considered decision. From the beginning on, the Dutch Dental Hygienists'Association has aimed at optimizing dental hygienists' role in preventive oral health care. Current developments, such as the introduction of a new national health insurance system and the rearrangement of oral health care, require reflection on the position of dental hygienists. Prevention should remain the core business of the dental hygiene profession. However, preventive oral health care has lost its social priority. Therefore, a new campaign preventing development of both old and new oral health threats should be initiated. In the opinion of the Dutch Dental Hygienists' Association, dental hygienists should be committed both to public and individual oral health prevention. The association pleads for the reinforcement of preventive oral health care for children and young adults, with a special focus on high-risk groups. Likewise, oral health care for elderly people should receive more attention. PMID:16886318

Dental Holography  

NASA Astrophysics Data System (ADS)

Ten years have passed since the first articles appeared in this new field. The qualities of the laser light together with the need of contactless 3-D measurements for different dental purposes seemed to be extremely promising, but still just a few scientists have used the method and mostly for laboratory studies. For some reason there has been a preponderance for orthodontic measurements. This seems to be a bit peculiar from holographic view compared with measurements for engineering purposes, which usually are made on metals. So naturally holography can become a clinical tool for measurements in the field of fixed bridges, removable partial dentures and implants. One of the problems is that the need for holography in dental research must be fulfilled in collaboration with physicists. Only a two-way communication during an entire experiment can balance both technical and odontological demands and thus give practical and clinical important results. The need for an easy way of handling the evaluation to get all required information is another problem and of course the holographic equipment must be converted to a box easy to handle for everyone. At last the position of dental holography today is going to be carefully examined together with an attempt to look into the hopefully exciting and not to utopic future for this research field.

Dental Fear among Medical and Dental Undergraduates  

PubMed Central

Objective. To assess the prevalence and level of dental fear among health related undergraduates and to identify factors causing such fear using Kleinknecht's Dental Fear Survey (DFS) questionnaire. Methods. Kleinknecht's DFS questionnaire was used to assess dental fear and anxiety among the entire enrollment of the medical and dental undergraduates' of the University of Malaya. Results. Overall response rate was 82.2%. Dental students reported higher prevalence of dental fear (96.0% versus 90.4%). However, most of the fear encountered among dental students was in the low fear category as compared to their medical counterpart (69.2 versus 51.2%). Significantly more medical students cancelled dental appointment due to fear compared to dental students (P = 0.004). “Heart beats faster” and “muscle being tensed” were the top two physiological responses experienced by the respondents. “Drill” and “anesthetic needle” were the most fear provoking objects among respondents of both faculties. Conclusion. Dental fear and anxiety are a common problem encountered among medical and dental undergraduates who represent future health care professionals. Also, high level of dental fear and anxiety leads to the avoidance of the dental services. PMID:25386615

Racial Disparities in Trajectories of Dental Caries Experience*  

PubMed Central

Objectives This study charted the trajectories of dental caries, including decayed teeth, missing teeth, and filled teeth among older Americans over a 5-year period. In particular, it focused on racial differences in the levels of and rates of change in dental caries experience. Methods Data came from the Piedmont Dental Study. The sample included 810 older Americans who were dentate at the baseline with up to 4 repeated observations between 1988 and 1994. Hierarchical linear models were employed in depicting intrapersonal and interpersonal differences in dental caries experience. Results Different measures of caries outcomes exhibited distinct trajectories. On average, the number of decayed teeth decreased over time, whereas missing teeth increased. In contrast, the number of filled teeth remained stable during a 5-year period. Relative to their white counterparts, older black Americans had more decayed teeth and missing teeth but fewer filled teeth. Blacks and whites differed in the levels of dental caries but not in their rates of change except for missing teeth. Even when demographic and socioeconomic attributes were adjusted, racial variations in dental caries experience remained significant. Conclusions Though significantly correlated, various dental caries outcomes move along different paths over time. In view of the persistent racial disparities in dental caries trajectories, future interventions to minimize such variations among older Americans in the levels of and the rates of change in dental caries experience are clearly warranted.

Reimbursing Dentists for Smoking Cessation Treatment: Views From Dental Insurers  

PubMed Central

Introduction: Screening and delivery of evidence-based interventions by dentists is an effective way to reduce tobacco use. However, dental visits remain an underutilized opportunity for the treatment of tobacco dependence. This is, in part, because the current reimbursement structure does not support expansion of dental providers’ role in this arena. The purpose of this study was to interview dental insurers to assess attitudes toward tobacco use treatment in dental practice, pros and cons of offering dental provider reimbursement, and barriers to instituting a tobacco use treatment-related payment policy for dental providers. Methods: Semi-structured interviews were conducted with 11 dental insurance company executives. Participants were identified using a targeted sampling method and represented viewpoints from a significant share of companies within the dental insurance industry. Results: All insurers believed that screening and intervention for tobacco use was an appropriate part of routine care during a dental visit. Several indicated a need for more evidence of clinical and cost-effectiveness before reimbursement for these services could be actualized. Lack of purchaser demand, questionable returns on investment, and segregation of the medical and dental insurance markets were cited as additional barriers to coverage. Conclusions: Dissemination of findings on efficacy and additional research on financial returns could help to promote uptake of coverage by insurers. Wider issues of integration between dental and medical care and payment systems must be addressed in order to expand opportunities for preventive services in dental care settings. PMID:22387994

Clinically Determined and Self-Reported Dental Caries Status During and After Pregnancy Among Low-Income Hispanic Women  

PubMed Central

Objectives This analysis assessed, during and one-year after pregnancy: 1) the prevalence of and relationship between self-reported and clinically determined dental caries and oral health status, and whether self-reports are a potential proxy for professional determination; 2) factors associated with high levels of professionally determined or self-reported oral disease. Methods Data are from a randomized clinical trial of 301 pregnant, low-income Hispanic women at the California-Mexico border to compare two interventions to prevent early childhood caries. Interviews and dental examinations were conducted at enrollment (second trimester) and one-year post-partum (PP). Results During pregnancy and PP, 93% had untreated caries and most had gingival inflammation. Sensitivity and specificity of self-reported measures compared to dentists’ determinations were modest (ranging from 45–80% for sensitivity and 41–77% for specificity at both time points); positive predictive values for women reporting current tooth decay or fair/poor oral health were high (>94%), but negative predictive values were low (<23%). In a bivariate GEE model, factors associated with fair/poor self-reported oral health during and after pregnancy included self-reported dental symptoms (current tooth decay, bleeding gums without brushing), dental behaviors (not flossing) and number of decayed tooth surfaces. In a logistic regression model, the only significant factor PP associated with less extensive untreated disease was if women ever had their teeth cleaned professionally (OR=0.44). Conclusions There is a great need for dental treatment in this underserved population both during pregnancy and PP. Women may not be able to accurately recognize or act on their treatment needs. At baseline and PP, few demographic or behavioral factors were associated with either self-reported or clinically-determined oral disease (e.g., being less educated or acculturated and not flossing) in the bivariate analyses. Ever having a professional teeth cleaning significantly predicted less disease PP. PMID:23889689

Dental Status of New Caledonian Children: Is There a Need for a New Oral Health Promotion Programme?  

PubMed Central

Background Before implementing a new oral health promotion program in the French overseas territory of Nouvelle Calédonie, the health authorities needed recent data about dental status of the New Caledonian child population. Objectives This study aimed to describe the dental status of 6, 9 and 12-yr-old New Caledonian children and to investigate the environmental and behavioural risk factors related to oral health. Methods A randomly selected sample of 2734 children (744 6-yr-olds, 789 9-yr-olds, and 1201 12-yr-olds) was examined clinically by seven calibrated investigators and participants responded to a questionnaire. The main variables were objective criteria about dental status and subjective criteria about experience of dental care, dental fear, self-perception of oral health, cultural or ethnic identity and environmental and behavioural risk factors. Results Overall, most of the children had infectious oral diseases: more than 50% had gingivitis, and 60% of 6- and 9 yr-olds had at least one deciduous or permanent tooth with untreated caries. The mean 12-yr-old number of decayed missing and filled teeth (DMFT) was 2.09±2.82. The number of carious lesions was related to the unfavourable lifestyle, deprived social status and no preventive dental care. Kanak, Polynesians and Caledonians (respectively 27%, 18% and 45% of the study sample) were more affected by caries than metropolitan French and Asian children. Children with many untreated carious lesions had negative perceptions of their oral health; they complained of chewing difficulty and had higher scores for dental anxiety. Conclusion This study highlights the need for new strategies aimed at improving oral health and at reducing inequalities in New Caledonia. An oral health promotion program would need to be developed in connection with other health programmes using the common risk factor approach within the context of the local environment.

The efficacy of a school-based caries preventive program: a 4-year study.  

PubMed

This longitudinal study aimed at testing the efficacy of a school-based caries preventive program, by comparing dental caries status of two groups, a study group (436 children) and a control group (420 children) over a period of 4 years. The study group received a preventive program which consisted of intensive oral hygiene instructions sessions, and supervised daily tooth brushing using fluoridated tooth paste in schools. The control group received only oral hygiene instructions sessions. Annual dental examination to record dental caries status, using Decayed Missed Filled Teeth Index (DMFT) and deft, was conducted for both groups over a period of 4 years. At the end of the fourth year the efficacy of the program was tested by comparing the DMFT and deft indices for the two groups using Pearson chi-square test and Cochran-Mantel-Haenzele test. The level of significance was set at P < 0.05. The results after 4 years showed that the caries status of the children in the study group was better than that of the control group. The difference was statistically significant (P-value 0.001). The estimates of relative risk values also showed that children in the control group are 3.1 and 6.4 times at higher risk of having dental caries than those in the study group for age group 12 and 6 respectively. This study proves that supervised daily tooth brushing using fluoridated toothpaste is successful in controlling dental caries in children. PMID:16451437

Application of the human needs conceptual model of dental hygiene to the role of the clinician : part II.  

PubMed

In summary, the theories of Maslow and of Yura and Walsh have been highlighted as background for understanding the human needs conceptual model of dental hygiene. In addition, 11 human needs have been identified and defined as being especially related to dental hygiene care, and a sample evaluation tool for their clinical assessment and a dental hygiene care plan have been presented. The four concepts of client, environment, health/oral health, and dental hygiene actions explained in terms of human need theory, and the 11 human needs related to dental hygiene care constitute the human needs conceptual model of dental hygiene. Within the framework of the human needs conceptual model of dental hygiene, the dental hygiene process is a systematic approach to dental hygiene care that involves assessment of the 11 human needs related to dental hygiene care; analysis of deficits in these needs; determination of the dental hygiene care plan based on identified deficits; implementation of dental hygiene interventions stated in the care plan; and evaluation of the effectiveness of dental hygiene interventions in achieving specific goals, including subsequent reassessment and revision of the dental hygiene care plan. This human needs conceptual model for dental hygiene provides a guide for comprehensive and humanistic client care. This model allows the dental hygienist to view each client (whether an individual or a group) holistically to prevent oral disease and to promote health and wellness. Dental hygiene theorists are encouraged to expand this model or to develop additional conceptual models based on dental hygiene's paradigm. PMID:17233167

Mouthrinses and dental caries.  

PubMed

Mouthrinsing for the prevention of dental caries in children and adolescents was established as a mass prophylactic method in the 1960s and has shown average efficacy of caries reduction between 20-50%. Commonly, weekly or twice monthly rinsing procedures using neutral 0.2% NaF solutions have been used in schools or institutions in areas with low fluoride concentrations in the drinking water. Today, when dental caries has declined substantially in the western countries, and relatively few individuals are suffering from caries, the efficiency of large scale mouthrinsing is questioned and more individual approaches of caries prevention strategies are needed. For this reason individual caries risk assessments are necessary, utilising diagnostic tools with the aim of explaining the main causes of the caries disease. Therefore in high risk patients, daily mouthrinses using 0.05% NaF can be recommended combined with other selective preventive measures such as sugar restriction, improved oral hygiene, antibacterial treatments, and so forth. Mouthrinsing solutions have therefore been combined with antiplaque agents like chlorhexidine and other agents which can improve the caries preventive effect not only in high caries risk patients, including those with dry mouth problems and root caries. Other agents than sodium fluoride have been used, such as stannous and amine fluoride with proven clinical effects. However, although a series of new formulas of mouthrinses containing fluoride combined with different antiplaque agents have shown promising antibacterial and antiplaque efficacy, their long-term clinical effects are sparsely documented. Acute and chronic side effects from established and recommended mouthrinsing routines are extremely rare but ethanol containing products should not be recommended to children for long-term use or to individuals with alcohol problems. Patients with dry mouth problems should avoid mouthrinses containing high concentration of detergent components which reduce the substantivity of the agent and worsen the dry mouth effect. For the future, patients, dentists and public health officials will welcome new and safe, controlled and self-administrated mouthrinsing procedures with not only high efficacy, but also high effectivity and efficiency.

Dental and Periodontal Health Status of Beta Thalassemia Major and Sickle Cell Anemic Patients: A Comparative Study  

PubMed Central

Background: This study aimed to assess the dental and periodontal health status of beta thalassemia major and sickle cell anemic patients in Bilaspur, Chattishgarh, India. Materials & Methods: A total of 750 patients were included in the study. The patients were randomly divided into three groups I (n=250), II (n=250) and III (n=250), ranging from 3-15 years. After performing a thourough general examination, including their demographic data, intraoral examination was done using Decayed-Missing-Filled Teeth Index (DMFT Index), Plaque index (PI) and Gingival index (GI). Statistical analysis was done using statistical software SPSS 17.5 version. Chi square test & student t test was used for the comparison of study and control groups. The level of significance was set at P<0.05. Results: In the present study, it was found that, prevalence of dental caries and periodontal diseases was significantly more in beta thalassemic patients followed by sickle cell anemic patients than control group. However, when group I (beta thalassemia) was compared with group II (sickle cell anemia), results were found to highly significant (P<0.001) only for decayed missing filled tooth. Conclusion: Appropriate dental and periodontal care improves a patient's quality of life. Preventive dental care is must for thalassemic and Sickle cell disease patients.

The Dental Plaque Microbiome in Health and Disease  

PubMed Central

Dental decay is one of the most prevalent chronic diseases worldwide. A variety of factors, including microbial, genetic, immunological, behavioral and environmental, interact to contribute to dental caries onset and development. Previous studies focused on the microbial basis for dental caries have identified species associated with both dental health and disease. The purpose of the current study was to improve our knowledge of the microbial species involved in dental caries and health by performing a comprehensive 16S rDNA profiling of the dental plaque microbiome of both caries-free and caries-active subjects. Analysis of over 50,000 nearly full-length 16S rDNA clones allowed the identification of 1,372 operational taxonomic units (OTUs) in the dental plaque microbiome. Approximately half of the OTUs were common to both caries-free and caries-active microbiomes and present at similar abundance. The majority of differences in OTU’s reflected very low abundance phylotypes. This survey allowed us to define the population structure of the dental plaque microbiome and to identify the microbial signatures associated with dental health and disease. The deep profiling of dental plaque allowed the identification of 87 phylotypes that are over-represented in either caries-free or caries-active subjects. Among these signatures, those associated with dental health outnumbered those associated with dental caries by nearly two-fold. A comparison of this data to other published studies indicate significant heterogeneity in study outcomes and suggest that novel approaches may be required to further define the signatures of dental caries onset and progression.

Association of dental and periodontal status with bisphosphonate-related osteonecrosis of the jaws. A retrospective case controlled study  

PubMed Central

Introduction To assess the association of oral hygiene, dental caries, and periodontal status with bisphosphonate-related osteonecrosis of the jaws. Material and methods A retrospective case-control study on 81 patients treated for neoplasms with bone metastases. Twenty-nine patients with bone necrosis and 52 controls treated with bisphosphonates were compared using the Oral Hygiene Index, Decay, Missing, Filled Teeth, Community Periodontal Index of Treatment Needs, and Residual Periodontal Bone. The null hypothesis stated that there was no difference in parameters of oral health between patients with and without bone necrosis. Differences of means of above-mentioned variables were compared between the groups with Student's t-test or Mann-Whitney rank sum test and ?2 test. Value of p ? 0.05 was considered significant. Results Poorer oral hygiene (OHIs 1.94 vs. 1.32; p = 0.065), more advanced dental caries (DMFT 26.85 vs. 22.87; p = 0.05), and more advanced periodontal disease (CPITN: = 0: 21.05% vs. 42.51%; = 1 13.16% vs. 7.29%; = 2: 0% vs. 15.38%; = 3: 65.79% vs. 28.34%; = 4: 0% vs. 6.48%, Residual periodontal bone 73.1% vs. 80.51%; p = 0,001) were characteristic of patients with bisphosphonate related jaw necrosis when compared with control group. An advanced dental caries or periodontal disease required surgical intervention which directly contributed to the development of the bone necrosis. Conclusions Dental and periodontal disease can lead to bisphosphonate-related osteonecrosis of the jaw. Oncologic patients treated with bisphosphonates should be offered preventive care to reduce dental plaque, calculus, dental caries, and periodontal disease. PMID:24701224

Oral health and dental care in Hong Kong.  

PubMed

With a population of six million people and situated at the South-eastern corner of mainland China, Hong Kong is considered as the gateway between East and West, often playing a role disproportionate to its territorial or population size. The FDI World Dental Congress 1995 provides an impetus to familiarise colleagues worldwide with the oral health and dental care situation in Hong Kong. Water fluoridation was introduced in 1961, which has achieved a continuous low and stable caries prevalence in children as well as in adults. Edentulousness among adults is usually not apparent until after age 55, but at much lower rates than in comparable western industrialised populations. Periodontal conditions in adults are dominated by calculus and shallow pockets. Overall, treatment needs are mainly oral hygiene and simple restorative treatment. Dental awareness is considered low with only a minority of the population seeking dental care on a regular basis. Traditional Chinese health beliefs are common and may influence health behaviour in terms of self- or professional care. Dental care is mainly provided by around 1000 private dental practitioners but special government dental programmes are established for primary school children, who are mainly treated by dental therapists, and for civil servants and their dependents. Dental hygienists are trained in very limited numbers. Dental specialties are under development as part of a newly established Academy of Medicine. Developments are under way to introduce new preventive oriented programmes for pre-school and secondary school age groups. PMID:7558355

Global burden of dental condition among children in nine countries participating in an international oral health promotion programme, 2012-2013.  

PubMed

The Live.Learn.Laugh. phase 2 programme is a unique global partnership between FDI World Dental Federation and Unilever Oral Care which aims to provide measurable improvement of oral health on a global scale through encouraging twice-daily brushing with a fluoride toothpaste. It was based on international recommendations using the principles of health promotion within school for the implementation of preventive health strategies. This paper is an overview of the dental caries condition of children from 2012 to 2013 in nine countries included in four World Health Organisation (WHO) regions. A cross-sectional study was conducted in each country before the implementation of health-promotion measures focused on twice-daily toothbrushing with fluoride toothpaste. The sample was based on stratified sampling according to the WHO pathfinder recommendations. From a total of 7,949 children examined, there were 517 children (1-2 years of age), 1,667 preschool children (3-5 years of age) and 5,789 schoolchildren (6-13 years of age). The prevalence and severity of primary dental caries, early childhood caries and temporary dental caries were described using decayed, filled teeth (dft), permanent decayed, missing, filled teeth (DMFT) indices and the significant caries index (SCI). The major findings were a high prevalence of caries, identification of high-risk groups and inequality in the distribution of the severity of dental conditions. Aggregated data from this overview should provide justification for implementing an oral health programme. The main point is the need to retain and expand the community fluoridation programme as an effective preventive measure. At the individual level, the aggregated data identify the need for more targeted efforts to reach children early - especially among specific high-risk groups. PMID:25209648

Dental Usage Under Changing Economic Conditions  

PubMed Central

Objective The purpose of this article is to examine the relationship between changes in household finances (wealth and income) and changes in dental utilization at the onset of the recent recession in a population of older Americans. Methods Data from the Health and Retirement Study (HRS) were analyzed for U.S. individuals aged 51 years and older during the 2006 and 2008 waves of the HRS. We estimated logistic models of (1) starting and (2) stopping dental use between 2006 and 2008 survey periods as a function of changes in household wealth and income, controlling for other potentially confounding covariates. Results We found that only when household wealth falls by 50 percent or more were older adults less likely to seek dental care. Changes in household income and other changes in household wealth were not associated with changes in dental utilization among this population. Conclusions Older Americans’ dental care utilization appeared to be fairly resilient to changes in household finances; only when wealth fell by 50 percent or more did individuals decrease dental use. This finding might extend to other health care services that are preventive, routine, and relatively inexpensive. PMID:22994647

[Dental technician's pneumoconiosis; a case report].  

PubMed

Since 1939, it has been known that, silicosis and extrinsic allergic alveolitis can be seen among dental technicians. The interstitial disease caused by the exposure to complex substances used by dental technicians is classified as a special group called dental technician's pneumoconiosis. A 36-year-old man, who has no smoking history, presented with severe dyspnea. He had worked in different dental laboratories for 22 years, but he did not have respiratory symptoms until five years ago. After that date, he had hospitalized and had been examined for respiratory pathologies for many times. He had came to our clinic, because of the progression of his dyspnea. Diffuse pulmonary parenchymal infiltrates which can be related with pneumoconiosis and chronic type 1 respiratory deficiency had been diagnosed as the result of the examinations. While he has no history of smoking or any other risk factors or diseases in his medical history, the case was accepted as dental technician's pneumoconiosis. The factors related with the pathogenesis of dental technician's pneumoconiosis are; the complex compound of the substances (metal dusts, silica, plaster, wax and resins, chemical liquids, methyl methacrylate) used in this sector and their effects on the lung parenchyma. Extrinsic allergic alveolitis related with methyl methacrylate has been reported. The most important factor to acquire an occupational lung disease is a complex occupational exposure. The insufficient workplace airing and the lack of preventive measures added on this exposure, the risks become much more greater. PMID:18701982

Silver Nanoparticles in Dental Biomaterials  

PubMed Central

Silver has been used in medicine for centuries because of its antimicrobial properties. More recently, silver nanoparticles have been synthesized and incorporated into several biomaterials, since their small size provides great antimicrobial effect, at low filler level. Hence, these nanoparticles have been applied in dentistry, in order to prevent or reduce biofilm formation over dental materials surfaces. This review aims to discuss the current progress in this field, highlighting aspects regarding silver nanoparticles incorporation, such as antimicrobial potential, mechanical properties, cytotoxicity, and long-term effectiveness. We also emphasize the need for more studies to determine the optimal concentration of silver nanoparticle and its release over time. PMID:25667594

Dental Implant Systems  

PubMed Central

Among various dental materials and their successful applications, a dental implant is a good example of the integrated system of science and technology involved in multiple disciplines including surface chemistry and physics, biomechanics, from macro-scale to nano-scale manufacturing technologies and surface engineering. As many other dental materials and devices, there are crucial requirements taken upon on dental implants systems, since surface of dental implants is directly in contact with vital hard/soft tissue and is subjected to chemical as well as mechanical bio-environments. Such requirements should, at least, include biological compatibility, mechanical compatibility, and morphological compatibility to surrounding vital tissues. In this review, based on carefully selected about 500 published articles, these requirements plus MRI compatibility are firstly reviewed, followed by surface texturing methods in details. Normally dental implants are placed to lost tooth/teeth location(s) in adult patients whose skeleton and bony growth have already completed. However, there are some controversial issues for placing dental implants in growing patients. This point has been, in most of dental articles, overlooked. This review, therefore, throws a deliberate sight on this point. Concluding this review, we are proposing a novel implant system that integrates materials science and up-dated surface technology to improve dental implant systems exhibiting bio- and mechano-functionalities.

Characterization of dental interfaces with electron tomography.  

PubMed

Understanding the interface between dental materials and tooth is critical in the prevention of secondary caries. Assessing this interface with high-resolution clarity has traditionally been challenging. This work highlights electron tomography, carried out in the transmission electron microscope, as a novel technique to obtain both three-dimensional and nanometer scaled information on dental materials in contact with dentin. In this study, commercial calcium aluminate and glass ionomer based luting agents in contact with human dentin were prepared for electron microscopy via focused ion beam milling. Imaging with high-angle annular dark field provided compositional contrast, and combined with tilting over large angular ranges, enabled the reconstruction of the three-dimensional interface between tissue and cement. The characteristics of the interface were observed with this extra dimensionality and superior resolution, providing evidence for the viability of this technique in interfacial studies of dental materials.

Arresting rampant dental caries with silver diamine fluoride in a young teenager suffering from chronic oral graft versus host disease post-bone marrow transplantation: a case report  

PubMed Central

Background Rampant caries is an advanced and severe dental disease that affects multiple teeth. This case describes the management of rampant caries in a young teenager suffering from chronic oral graft versus host disease after allogeneic bone marrow transplantation. Case presentation A 14-year-old Chinese boy suffering from ?–thalassemia major was referred to the dental clinic for the management of rampant dental caries. An oral examination revealed pale conjunctiva, bruising of lips, and depapillation of tongue indicating an underlying condition of anemia. The poor oral condition due to topical and systemic immunosuppressants was seriously aggravated, and rampant caries developed rapidly, affecting all newly erupted, permanent teeth. The teeth were hypersensitive and halitosis was apparent. Strategies for oral health education and diet modification were given to the patient. Xylitol chewing gum was used to stimulate saliva flow to promote remineralization of teeth. Silver diamine fluoride was topically applied to arrest rampant caries and to relieve pain from hypersensitivity. Carious teeth with pulpal involvement were endodontically treated. Stainless steel crowns were provided on molars to restore chewing function, and polycarbonate crowns were placed on premolars, upper canines and incisors. Conclusion This case report demonstrates success in treating a young teenager with severe rampant dental decay by contemporary caries control and preventive strategy. PMID:24383434

What is dental ecology?  

PubMed

Teeth have long been used as indicators of primate ecology. Early work focused on the links between dental morphology, diet, and behavior, with more recent years emphasizing dental wear, microstructure, development, and biogeochemistry, to understand primate ecology. Our study of Lemur catta at the Beza Mahafaly Special Reserve, Madagascar, has revealed an unusual pattern of severe tooth wear and frequent tooth loss, primarily the result of consuming a fallback food for which these primates are not dentally adapted. Interpreting these data was only possible by combining our areas of expertise (dental anatomy [FC] and primate ecology [MS]). By integrating theoretical, methodological, and applied aspects of both areas of research, we adopted the term "dental ecology"-defined as the broad study of how teeth respond to the environment. Specifically, we view dental ecology as an interpretive framework using teeth as a vehicle for understanding an organism's ecology, which builds upon earlier work, but creates a new synthesis of anatomy and ecology that is only possible with detailed knowledge of living primates. This framework includes (1) identifying patterns of dental pathology and tooth use-wear, within the context of feeding ecology, behavior, habitat variation, and anthropogenic change, (2) assessing ways in which dental development and biogeochemical signals can reflect habitat, environmental change and/or stress, and (3) how dental microstructure and macro-morphology are adapted to, and reflect feeding ecology. Here we define dental ecology, provide a short summary of the development of this perspective, and place our new work into this context. PMID:22610892

Prevention of periodontal disease.  

PubMed

Periodontal disease is the most common disease affecting adult dogs and cats. It is also a very preventable disease. The insidious nature of the disease and requirement for the pet owner to be actively involved make client and public education absolutely vital. Although clients are commonly aware of their pets' bad breath, they rarely notice gingivitis, fractured teeth, and traumatic malocclusions. The annual National Pet Dental Health Month program has resulted in a tremendous increase in public awareness. Veterinarians must carry this further in their everyday practices, convincing our clients of the need for preventive dental care. It is only through clients' ongoing desire and persistence that a long-term preventive program can be successful. This requires a coordinated effort by the entire hospital staff. When successful, clients' pets will live healthier and longer lives. PMID:9779544

Extension for prevention: is it relevant today?  

PubMed

Extension for prevention has been an integral part of dentistry for over 100 years. Because this concept advocated the removal of sound tooth structure, it was not totally accepted at the turn of the century. The advent of the gold casting catapulted extension for prevention into general acceptance. In 1883, Webb presented a concept of "prevention of extension of decay". This concept advocated a proximal cavity preparation extending toward the buccal and lingual aspects of the tooth so that contact with adjacent teeth would not be at the margins. The separation of the margins, along with proper restoration contours, was thought to promote natural cleansing of the embrasures with saliva and fluids in the diet. GV Black's 1891 idea of "extension for prevention" was to provide extension of the preparation to the facial and lingual line angles in order to bring about "self-cleansing" margins via food excursion. Black's concept also included extending preparations through fissures to allow cavosurface margins to be on non-fissured enamel. Black integrated the extension of the proximal margins with his concept of an occlusal isthmus for a Class II amalgam preparation one-third the faciolingual width of the occlusal surface. Challenges to this concept of extension for prevention were immediate; and, by the 1950's, narrower, more conservative preparations were seen by a few as being more effective in preserving teeth. Not only occlusal width was reassessed, but the need to routinely extend proximal margins to the buccal and lingual line angles was also questioned. By the mid-1960's and early 1970's a more conservative approach to amalgam preparation was advocated and was being taught in some dental schools. Today, a standardized outline form should not be used or taught as a principle of cavity preparation. In areas where fissure caries has necessitated a preparation extending into dentin, a composite resin or dental amalgam restoration should be placed, and a fissure sealant should be used to protect remaining susceptible fissures from carious attack. This current form of the concept of extension for prevention, which is supported by clinical research, preserves sound tooth structure that, using outdated concepts, would have been cut away. Placing proximal margins in sound tooth structure that just clears an adjacent tooth is also strongly advocated. Sound enamel margins in certain areas may occasionally be left in contact with adjacent teeth for amalgam preparations. For Class II preparations for composite resin, facial or lingual proximal bevels will usually suffice to separate the margins from the adjacent tooth to allow finishing and polishing at the margins. Preventing unnecessary extension and allowing sounder tooth structure to remain is one important aspect of helping patients to maintain their teeth for their lifetimes. PMID:10388375

Research defines public dental health promotion in youth.  

PubMed

In the Netherlands, Dental Public Health Service workers work in the healthcare delivery system to promote dental health. Since 1994, research has been conducted in Flevoland on the condition of children's teeth. This research has shaped the content of the dental health promotion directed at children in this region. The research comprises two parts: questionnaires for parents and children above the age of 12 and a dental examination of children aged 6 and 12 in the regional primary schools. The dental examination registers the health of the children's teeth. Sound teeth are defined as being free of visible caries and/or restoration. Not sound teeth show at least one case of visible caries and/or restoration. The research results have shown great dental differences between the various schools and between municipalities. The percentage of children with sound teeth ranges between 28 and 100 per school. Based on the final results of the research, an information pack will be disseminated. In the case of high-risk schools the dental health promotion will be conducted more intensively. The Dental Public Health Service workers will give information sessions to groups of parents and children, the dentist and the dental hygienist will provide individual information and prevention. At the child health clinic (consultatiebureau), education will be provided to parents of children ranging in age from 0 to 4. This combined approach has proven to be effective on a large majority of the children. To ensure uniform dental health promotion, information protocols are used in these promotion activities within Flevoland. PMID:16451436

[Dental caries--therapeutic possibilities].  

PubMed

Contemporary tendencies in dentistry are based on the concept of maximal protection of healthy tooth tissues. Caries removal has been done traditionally with mechanical rotary instruments that are fast and precise. However, conventional cavity preparation has potential adverse effects to the pulp due to heat, pressure and vibrations. Moreover, drilling often causes pain and requires local anaesthesia, and these procedures are frequently perceived as unpleasant. Etiology, development and prevention of dental caries are better understood today and new restorative materials that bond micromechanically and/or chemically to dental tissues have been introduced. Thus, development of a new, less destructive caries removal technique is allowed. In the last decades, many alternative methods have been introduced in an attempt to replace rotary instruments. These are claimed to be efficient and selective for diseased tissues and to offer comfortable treatment to the patients. New methods include air abrasion, air polishing, ultrasonic, polymer burs, enzymes, systems for chemo-mechanical caries removal, and lasers. The aim of this paper was to discuss various caries removal techniques and possibilities of their use in clinical practice. Based on the literature review it can be concluded that none of the new caries removal methods can completely replace conventional rotary instruments. PMID:19177833

Dental arch asymmetry  

PubMed Central

Objective: This study was conducted to assess the dental arch asymmetry in a Yemeni sample aged (18-25) years. Materials and Methods: The investigation involved clinical examination of 1479 adults; only 253 (129 females, 124 males) out of the total sample were selected to fulfill the criteria for the study sample. Study models were constructed and evaluated to measure mandibular arch dimensions. Three linear distances were utilized on each side on the dental arch: Incisal-canine distance, canine-molar distance and incisal-molar distance, which represent the dental arch segmental measurements. Results: When applying “t-test” at P < 0.05, no significant differences were found between the right and left canine-molar, incisal-canine and incisal-molar distances in both dental arches for both sexes. The greater variation (0.30 mm) was observed between right and left canine-molar distance in the maxillary dental arch in male and the smaller (0.04 mm) in the mandibular dental arch between the right and left canine-molar distance in females. Conclusion: The findings of the present study revealed a symmetrical pattern of dental arches, since the right and left sides showed no statistically significant difference. In general, it can be observed that the measurements related to the central incisors and canines have the widest range of reading and give the impression that the location of central incisor and canines to each other and to other teeth is the strongest factor in determining the dental arch asymmetry.

Explaining Racial/Ethnic Disparities in Children’s Dental Health: A Decomposition Analysis  

PubMed Central

Objectives. We measured racial/ethnic inequalities in US children’s dental health and quantified the contribution of conceptually relevant factors. Methods. Using data from the 2007 National Survey of Children’s Health, we investigated racial/ethnic disparities in selected child dental health and preventive care outcomes. We employed a decomposition model to quantify demographic, socioeconomic, maternal health, health insurance, neighborhood, and geographic effects. Results. Hispanic children had the poorest dental health and lowest preventive dental care utilization, followed by Black then White children. The model explanatory variables accounted for 58% to 77% of the disparities in dental health and 89% to 100% of the disparities in preventive dental care. Socioeconomic status accounted for 71% of the gap in preventive dental care between Black children and White children and 55% of that between Hispanic children and White children. Maternal health, age, and marital status; neighborhood safety and social capital; and state of residence were relevant factors. Conclusions. Reducing US children’s racial/ethnic dental health disparities—which are mostly socioeconomically driven—requires policies that recognize the multilevel pathways underlying them and the need for household- and neighborhood-level interventions.

Minimal Intervention Dentistry (MID) for managing dental caries – a review  

PubMed Central

This publication describes the history of Minimal Intervention Dentistry (MID) for managing dental caries and presents evidence for various carious lesion detection devices, for preventive measures, for restorative and non-restorative therapies as well as for repairing rather than replacing defective restorations. It is a follow-up to the FDI World Dental Federation publication on MID, of 2000. The dental profession currently is faced with an enormous task of how to manage the high burden of consequences of the caries process amongst the world population. If it is to manage carious lesion development and its progression, it should move away from the ‘surgical’ care approach and fully embrace the MID approach. The chance for MID to be successful is thought to be increased tremendously if dental caries is not considered an infectious but instead a behavioural disease with a bacterial component. Controlling the two main carious lesion development related behaviours, i.e. intake and frequency of fermentable sugars, to not more than five times daily and removing/disturbing dental plaque from all tooth surfaces using an effective fluoridated toothpaste twice daily, are the ingredients for reducing the burden of dental caries in many communities in the world. FDI’s policy of reducing the need for restorative therapy by placing an even greater emphasis on caries prevention than is currently done, is therefore, worth pursuing. PMID:23106836

Awareness of emergency management of dental trauma  

PubMed Central

Aim: Traumatic dental injuries frequently occur in society and may occur at home. The ultimate prognosis of an avulsed tooth occurring in a child may depend on the parents’ knowledge of appropriate emergency measures. This study is aimed at evaluating the awareness level of a sample of Indian (Rohtak, Haryana) parents in the management of dental trauma. Materials and Methods: A total of 1500 parents were surveyed using a self-administered structured questionnaire. The questionnaire was divided into three parts. The tabulated data were statistically analyzed using the Chi-square test. Result: This study indicated a low level of knowledge regarding tooth avulsion and replantation procedures to be followed in emergency. The residing area and age of parent did not affect the knowledge and awareness of parents. Moreover, well-educated parents also had very little or no information about dental trauma first-aid. The lack of significance in correct answers between those with and without such experience indicated that past experience did not seem to have increase the knowledge of the correct emergency procedures. Very little or no information about tooth avulsion and replantation had been given to most of them. Conclusion: Dental injury prevention and management should be recognized as a major public health issue and adequate resources to be allocated for research in this area. Educational programs to improve the knowledge and awareness among the parents have to be implemented. PMID:25395768

Influence of dental materials on dental MRI  

PubMed Central

Objectives: To investigate the potential influence of standard dental materials on dental MRI (dMRI) by estimating the magnetic susceptibility with the help of the MRI-based geometric distortion method and to classify the materials from the standpoint of dMRI. Methods: A series of standard dental materials was studied on a 1.5?T MRI system using spin echo and gradient echo pulse sequences and their magnetic susceptibility was estimated using the geometric method. Measurements on samples of dental materials were supported by in vivo examples obtained in dedicated dMRI procedures. Results: The tested materials showed a range of distortion degrees. The following materials were classified as fully compatible materials that can be present even in the tooth of interest: the resin-based sealer AH Plus® (Dentsply, Maillefer, Germany), glass ionomer cement, gutta-percha, zirconium dioxide and composites from one of the tested manufacturers. Interestingly, composites provided by the other manufacturer caused relatively strong distortions and were therefore classified as compatible I, along with amalgam, gold alloy, gold–ceramic crowns, titanium alloy and NiTi orthodontic wires. Materials, the magnetic susceptibility of which differed from that of water by more than 200?ppm, were classified as non-compatible materials that should not be present in the patient’s mouth for any dMRI applications. They included stainless steel orthodontic appliances and CoCr. Conclusions: A classification of the materials that complies with the standard grouping of materials according to their magnetic susceptibility was proposed and adopted for the purposes of dMRI. The proposed classification can serve as a guideline in future dMRI research. PMID:23610088

Esthetic dental anomalies as motive for bullying in schoolchildren  

PubMed Central

Facial esthetics, including oral esthetics, can severely affect children's quality-of-life, causing physical, social and psychological impairment. Children and adolescents with esthetic-related dental malformations are potential targets for bullies. This study was aimed to present and discuss patients who suffered from bullying at school and family environment due to esthetic-related teeth anomalies. Providing an adequate esthetic dental treatment is an important step in their rehabilitation when the lack of esthetic is the main source of bullying. After dental treatment, we noted significant improvement in self-esteem, self-confidence, socialization and academic performance of all patients and improvement in parental satisfaction regarding the appearance of their children. It is imperative that both family and school care providers be constantly alert about bullying in order to prevent or interrupt aggressive and discriminatory practices against children and adolescents. Clearly, dental anomalies may be a motive for bullying. PMID:24966759

Frequency and Risk Indicators of Tooth Decay among Pregnant Women in France: A Cross-Sectional Analysis  

PubMed Central

Introduction Little is known on the prevalence of tooth decay among pregnant women. Better knowledge of tooth decay risk indicators during pregnancy could help to develop follow-up protocols for women at risk, along with better prevention strategies. The aim of this study was to assess the frequency of tooth decay and the number of decayed teeth per woman in a large sample of pregnant women in France, and to study associated risk indicators. Methods A secondary cross-sectional analysis of data from a French multicentre case-control study was performed. The sample was composed of 1094 at-term women of six maternity units. A dental examination was carried out within 2 to 4 days post-partum. Socio-demographic and behavioural characteristics were obtained through a standardised interview with the women. Medical characteristics were obtained from the women’s medical records. Risk indicators associated with tooth decay were identified using a negative binomial hurdle model. Results 51.6% of the women had tooth decay. The mean number of decayed teeth among women having at least one was 3.1 (s.d.?=?2.8). Having tooth decay was statistically associated with lower age (aOR?=?1.58, 95%CI [1.03,2.45]), lower educational level (aOR?=?1.53, 95%CI [1.06,2.23]) and dental plaque (aOR?=?1.75, 95%CI [1.27,2.41]). The number of decayed teeth was associated with the same risk indicators and with non-French nationality and inadequate prenatal care. Discussion The frequency of tooth decay and the number of decayed teeth among pregnant women were high. Oral health promotion programmes must continue to inform women and care providers about the importance of dental care before, during and after pregnancy. Future research should also assess the effectiveness of public policies related to oral health in target populations of pregnant women facing challenging social or economic situations. PMID:22586442

Degradability of dental ceramics.  

PubMed

The degradation of dental ceramics generally occurs because of mechanical forces or chemical attack. The possible physiological side-effects of ceramics are their tendency to abrade opposing dental structures, the emission of radiation from radioactive components, the roughening of their surfaces by chemical attack with a corresponding increase in plaque retention, and the release of potentially unsafe concentrations of elements as a result of abrasion and dissolution. The chemical durability of dental ceramics is excellent. With the exception of the excessive exposure to acidulated fluoride, ammonium bifluoride, or hydrofluoric acid, there is little risk of surface degradation of virtually all current dental ceramics. Extensive exposure to acidulated fluoride is a possible problem for individuals with head and/or neck cancer who have received large doses of radiation. Such fluoride treatment is necessary to minimize tooth demineralization when saliva flow rates have been reduced because of radiation exposure to salivary glands. Porcelain surface stains are also lost occasionally when abraded by prophylaxis pastes and/or acidulated fluoride. In each case, the solutes are usually not ingested. Further research that uses standardized testing procedures is needed on the chemical durability of dental ceramics. Accelerated durability tests are desirable to minimize the time required for such measurements. The influence of chemical durability on surface roughness and the subsequent effect of roughness on wear of the ceramic restorations as well as of opposing structures should also be explored on a standardized basis.

Long-term patterns of dental attendance and caries experience among British adults: a retrospective analysis.  

PubMed

There is inconclusive evidence on the value of regular dental attendance. This study explored the relationship between long-term patterns of dental attendance and caries experience. We used retrospective data from 3,235 adults, ?16 yrs of age, who participated in the Adult Dental Health Survey in the UK. Participants were classified into four groups (always, current, former, and never regular-attenders) based on their responses to three questions on lifetime dental-attendance patterns. The association between dental-attendance patterns and caries experience, as measured using the decayed, missing, or filled teeth (DMFT) index, was tested in negative binomial regression models, adjusting for demographic (sex, age, and country of residence) and socio-economic (educational attainment, household income, and social class) factors. A consistent pattern of association between long-term dental attendance and caries experience was found in adjusted models. Former and never regular-attenders had a significantly higher DMFT score and numbers of decayed and missing teeth, but fewer filled teeth, than always regular-attenders. No differences in DMFT or its components were found between current and always regular-attenders. The findings of this study show that adults with different lifetime trajectories of dental attendance had different dental statuses. PMID:25521216

Osteoradionecrosis prevention myths  

SciTech Connect

Purpose: To critically analyze controversial osteoradionecrosis (ORN) prevention techniques, including preradiation extractions of healthy or restorable teeth and the use of prophylactic antibiotics or hyperbaric oxygen (HBO) treatments for preradiation and postradiation extractions. Methods: The author reviewed ORN studies found on PubMed and in other article references, including studies on overall ORN incidence and pre- and postradiation incidence, with and without prophylactic HBO or antibiotics. Results: Owing in part to more efficient radiation techniques, the incidence of ORN has been declining in radiation patients over the last 2 decades, but the prevention of ORN remains controversial. A review of the available literature does not support the preradiation extraction of restorable or healthy teeth. There is also insufficient evidence to support the use of prophylactic HBO treatments or prophylactic antibiotics before extractions or other oral surgical procedures in radiation patients. Conclusions: To prevent ORN, irradiated dental patients should maintain a high level of oral health. A preradiation referral for a dental evaluation and close collaboration by a multidisciplinary team can be invaluable for radiation patients. As with most other dental patients, restorable and healthy teeth should be retained in irradiated patients. The use of prophylactic HBO or antibiotics should be reconsidered for preradiation and postradiation extractions.

Pneumoconiosis and exposures of dental laboratory technicians.  

PubMed Central

One hundred and seventy-eight dental laboratory technicians and 69 non-exposed controls participated in an epidemiological respiratory study. Eight technicians who had a mean of 28 years' grinding nonprecious metal alloys were diagnosed as having a simple pneumoconiosis by chest radiograph. Mean values for per cent predicted FVC and FEV1 were reduced among male nonsmoker technicians compared to male nonsmoker controls; after controlling for age, there was also a reduction in spirometry with increasing work-years. An industrial hygiene survey was conducted in 13 laboratories randomly selected from 42 laboratories stratified by size and type of operation in the Salt Lake City, Utah metropolitan area. Personal exposures to beryllium and cobalt exceeded the Threshold Limit Values (TLVs) in one laboratory. Occupational exposures in dental laboratories need to be controlled to prevent beryllium-related lung disorders as well as simple pneumoconiosis. PMID:6496819

Objective: Dental caries is one of the most common infectious diseases worldwide. Saliva has many functions in the oral cavity and is the first line defense against dental caries. Oxidative stress can affect initiation and progression of many inflammatory and infectious diseases such as dental caries. Thus the aim of this study was to evaluate the relationship between total antioxidant capacity (TAC) of saliva and dental caries. Study Design: 100 healthy high school students (50 female and 50 male) with age range of 15 -17 years were randomly selected, divided to four groups. Unstimulated whole saliva specimens were collected at the morning. TAC of saliva was evaluated by spectrophotometric assay. Statistical comparisons were performed using Student’s t-test, by SPSS 13. Results: The level of TAC was significantly higher in the saliva of caries active group relative to the caries free subjects. Statistical analysis for male and female groups showed a statistically significant reduction of TAC level in female group. Conclusion: TAC was higher in caries active group. Thus this result showed that total antioxidant capacity may influence in dental caries and activity can be measured by salivary factors and this may be helpful in preventive dentistry. Key words:Dental caries, saliva, total antioxidant capacity. PMID:23524431

Risk factors associated with asthma phenotypes in dental healthcare workers  

PubMed Central

Background Exposure in the dental environment can increase the risk of respiratory disease in dental healthcare workers (HCWs). This study investigated the prevalence of asthma phenotypes in dental HCWs and associated risk factors. Methods A cross-sectional study of 454 dental HCWs in five dental institutions in South Africa was conducted. A self-administered questionnaire elicited the health and employment history of subjects. Sera was analysed for atopic status and latex sensitization. Pre and post bronchodilator spirometry was performed. Results The prevalence of atopic asthma was 6.9%, non-atopic asthma 5.9% and work-exacerbated asthma (WEA) 4.0%. Atopy and work-related ocular-nasal symptoms were strong predictors of WEA (OR: 3.4; 95% CI: 1.07 –10.8; OR: 6.7, 95% CI: 2.4 – 19.1), respectively. Regular use of personal protective equipment (PPE) was associated with a protective affect (OR: 0.23, 95% CI: 0.1 – 0.7) among non-atopic asthmatics, while glove use and respiratory protection was protective among atopic asthmatics (OR: 0.39, 95% CI: 0.17 – 0.89). Conclusion Identification of risk factors associated with specific asthma phenotypes in dental HCWs can be used to focus preventive strategies for asthmatics. PMID:22473580

Oral-dental concerns of the pediatric oncology patient  

SciTech Connect

One of the main concerns of all disciplines in health care today is maintaining the patient's quality of life and comfort during cancer therapy. Oral complications resulting from radiation or chemotherapy can be expected in a large percentage of patients. Conducting a dental evaluation and performing treatment before therapy can help prevent or lessen potential complications. With preventive care and fewer infections, the patient will be able to communicate with friends and family, and optimum care and comfort can be provided.

FATIGUE OF DENTAL CERAMICS  

PubMed Central

Objectives Clinical data on survival rates reveal that all-ceramic dental prostheses are susceptible to fracture from repetitive occlusal loading. The objective of this review is to examine the underlying mechanisms of fatigue in current and future dental ceramics. Data/sources The nature of various fatigue modes is elucidated using fracture test data on ceramic layer specimens from the dental and biomechanics literature. Conclusions Failure modes can change over a lifetime, depending on restoration geometry, loading conditions and material properties. Modes that operate in single-cycle loading may be dominated by alternative modes in multi-cycle loading. While post-mortem examination of failed prostheses can determine the sources of certain fractures, the evolution of these fractures en route to failure remains poorly understood. Whereas it is commonly held that loss of load-bearing capacity of dental ceramics in repetitive loading is attributable to chemically-assisted 'slow crack growth' in the presence of water, we demonstrate the existence of more deleterious fatigue mechanisms, mechanical rather than chemical in nature. Neglecting to account for mechanical fatigue can lead to gross overestimates in predicted survival rates. Clinical significance Strategies for prolonging the clinical lifetimes of ceramic restorations are proposed based on a crack-containment philosophy. PMID:24135295

European core curriculum in cariology for undergraduate dental students.  

PubMed

As dental caries prevalence is still high in many populations and groups of both children and adults worldwide, and as caries continues to be responsible for significant health, social and economic impacts, there is an urgent need for dental students to receive a systematic education in cariology based upon current best evidence. Although European curriculum guidelines for undergraduate students have been prepared in other dental fields over the last decade, none exist for cariology. Thus the European Organisation for Caries Research (ORCA) formed a task force to work with the Association of Dental Education in Europe (ADEE) on a European Core Curriculum in Cariology. In 2010, a workshop to develop such a curriculum was organised in Berlin, Germany, with 75 participants from 24 European and 3 North-South American countries. The Curriculum was debated by five pre-identified working groups: I The Knowledge Base; II Risk Assessment, Diagnosis and Synthesis; III Decision-making and Preventive Non-surgical Therapy; IV Decision-making and Surgical Therapy; and V Evidence-based Cariology in Clinical and Public Health Practice and then finalised jointly by the group chairs. According to this Curriculum, on graduation, a dentist must be competent at applying knowledge and understanding of the biological, medical, basic and applied clinical sciences in order to recognise caries and make decisions about its prevention and management in individuals and populations. This document, which presents several major and numerous supporting competences, does not confine itself to dental caries alone, but refers also to dental erosion/non-erosive wear and other dental hard tissue disorders.

Self-reported dental hygiene, obesity, and systemic inflammation in a pediatric rural community cohort  

PubMed Central

Background A growing body of epidemiologic evidence links oral health, obesity, and cardiovascular health, though few studies have reported on these relationships in children. While underlying mechanisms are unclear, adult studies have suggested sub-acute systemic inflammation, also implicated in the etiology of both obesity and cardiovascular disease. This study investigated associations between self-reported dental hygiene, obesity, and systemic inflammation in children. Methods 128 children < 19 years of age from rural counties in West Virginia participated in a community-based health screening that included anthropometric assessments, blood collection, and a questionnaire about dental hygiene and self-assessed oral health. Results Participants ranged from 3.0-18.7 years. Univariate analysis demonstrated an association between parent-reported dental hygiene, including frequency of preventive dental care and parent-assessed overall dental health, and markers of systemic inflammation but not obesity. In multivariable regression, parent-assessed overall dental health and obesity were independent predictors of systemic inflammation, after adjustment for age, gender, and parent education. Conclusions This is the first known study of the association between dental hygiene, obesity, and systemic inflammation in children. These results highlight the importance of preventive dental care in overall, systemic health in children and are consistent with previous reports in adults. PMID:20849640

Prevalence of dental caries among 12–14 year old children in Qatar  

PubMed Central

Background 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. Objectives 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. Materials and methods 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. Results 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. Conclusion 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. PMID:25057232

The Impact of a Home Visiting Program on Children’s Utilization of Dental Services  

PubMed Central

BACKGROUND: Child Health Investment Partnership (CHIP) of Roanoke Valley is a home visiting program that promotes children’s health and family self-sufficiency. CHIP’s Begin With a Grin program provides preventive dental services in the home (oral health anticipatory guidance and fluoride varnish) for children aged 0 to 6 years. The purpose of this study was to compare the dental utilization of Medicaid-enrolled children in CHIP versus Medicaid-enrolled children not in CHIP. METHODS: Using the propensity score method, control subjects were selected from the statewide Medicaid database by using a caliper-matching algorithm. A vector of chosen covariates was used to match control subjects; these covariates included risk factors, estimated propensity score, age, race, gender, and days of Medicaid eligibility. Propensity scores were developed by using a logistic regression. Differences in dental utilization outcomes were tested: ?1 dental claim (logistic regression) and number of dental claims (Poisson regression) for each subject within the test period. RESULTS: When CHIP children were compared with Medicaid-only children, the CHIP child was 3 times more likely to have at least 1 dental visit (odds ratio: 3.0 [95% confidence interval: 1.9–4.7]) and have a higher number of dental claims (ratio of estimated average number of dental claims [cases/control]: 8.60/3.05 = 2.82 [95% confidence interval: 2.56–3.12]). CONCLUSIONS: A home visiting model can introduce children and their families to dental prevention, improve dental health literacy, establish a dental home, and provide application of fluoride varnish.

Increased Use of Dental Services by Children Covered by Medicaid: 2000–2010  

PubMed Central

This report analyzes the use of dental services by children enrolled in Medicaid from federal fiscal years (FFY) 2000 to 2010. The number and percent of children receiving dental services under Medicaid climbed continuously over the decade. In FFY 2000, 6.3 million children ages 1 to 20 were reported to receive some form of dental care (either preventive or treatment); the number more than doubled to 15.4 million by FFY 2010. Part of the increase was because the overall number of children covered by Medicaid rose by 12 million (50%), but the percentage of children who received dental care climbed appreciably from 29.3% in FFY 2000 to 46.4% in FFY 2010. In that same time period, the number of children ages 1 to 20 receiving preventive dental services climbed from a reported 5.0 million to 13.6 million, while the percentage of children receiving preventive dental services rose from 23.2% to 40.8%. For children ages 1 to 20 who received dental treatment services, the reported number rose from 3.3 million in FFY 2000 to 7.6 million in FFY 2010. The percentage of children who obtained dental treatment services increased from 15.3% to 22.9%. In FFY 2010, about one sixth of children covered by Medicaid (15.7%) ages 6-14 had a dental sealant placed on a permanent molar. While most states have made steady progress in improving children's access to dental care in Medicaid over the past decade, there is still substantial variation across states and more remains to be done.

Open wide: looking into the safety culture of dental school clinics.  

PubMed

Although dentists perform highly technical procedures in complex environments, patient safety has not received the same focus in dentistry as in medicine. Cultivating a robust patient safety culture is foundational to minimizing patient harm, but little is known about how dental teams view patient safety or the patient safety culture within their practice. As a step toward rectifying that omission, the goals of this study were to benchmark the patient safety culture in three U.S. dental schools, identifying areas for improvement. The extensively validated Medical Office Survey on Patient Safety Culture (MOSOPS), developed by the Agency for Healthcare Research and Quality, was administered to dental faculty, dental hygienists, dental students, and staff at the three schools. Forty-seven percent of the 328 invited individuals completed the survey. The "Teamwork" category received the highest marks and "Patient Care Tracking and Follow-Up" and "Leadership Support for Patient Safety" the lowest. Only 48 percent of the respondents rated systems and processes in place to prevent/catch patient problems as good/excellent. All patient safety dimensions received lower marks than in medical practices. These findings and the inherent risk associated with dental procedures lead to the conclusion that dentistry in general, and academic dental clinics in particular, stands to benefit from an increased focus on patient safety. This first published use of the MOSOPS in a dental clinic setting highlights both clinical and educational priorities for improving the safety of care in dental school clinics. PMID:24789834

Dental problems in athletes.  

PubMed

Orofacial injuries and diseases occur in athletes, and they may not always have access to dentists. Therefore team physicians should be aware of the common injuries and initial management. Treatment of dental injuries will depend on whether the teeth are primary or permanent. The most common type of fracture is crown fracture, but there are other dental injuries that can lead to future complications if not treated promptly and monitored closely. Tooth avulsions need to be handled properly, and athletes should see a dentist as soon as possible. Despite the urgency of some injuries, other orofacial injuries or diseases, such as lacerations and caries, should not be overlooked. Proper education and use of mouth guards can assist athletes in reducing their risk of orofacial injuries. PMID:25574879

Ecology of dental disease.  

PubMed

Trace elements in the dental enamel of 43 prehistoric Indians from Illinois, Maryland and Virginia show concentration differences by age, sex and geographical locality. Sample areas on an incisor or first molar were blocked off with paraffin, washed twice with distilled water and etched 7 times with 6N HCl. An optical emission spectrophotometer was used to analyze the 9 samples, representing surface contamination and sequential enamel layers. Al, B, Ba, Cu, Fe, K, Mg, Mn, Na, Si, Sr, and Ti were present in most samples in micro or trace quantities; other elements were detected with less regularity. Comparisons of the 2 water washes with the 3 superficial, 4 deep and 7 total acid etches, suggest that during burial the residual inorganic portion of the enamel exchanged little or nothing with the soil. Enamel from archeological teeth may therefore be utilized in host factor studies in dental paleopathology. The Jy 50 Illinois Indians differ from the Potomac Creek, Virginia, Indians both in quantities of elements present and in internal sample variability. In each group, the sexes differ in 4 or more elements, both as to content and variability. Similarly, the older half of each sample differs from the younger. Patterns of sex and age difference are irregular, suggesting cultural differences, rather than physiological, in utilizing the environment during enamel-forming years. Enamel composition, as affected by differential environment utilization, may partially explain sex, age and geographical differences in dental pathology rates. PMID:998760

The effect of xylitol on dental caries and oral flora  

PubMed Central

Dental caries, the most chronic disease affecting mankind, has been in the limelight with regard to its prevention and treatment. Professional clinical management of caries has been very successful in cases of different severities of disease manifestations. However, tertiary management of this disease has been gaining attention, with numerous methods and agents emerging on a daily basis. Higher intake of nutritive sweeteners can result in higher energy intake and lower diet quality and thereby predispose an individual to conditions like obesity, cardiovascular disorders, and type 2 diabetes mellitus. Non-nutritive sweeteners have gained popularity as they are sweeter and are required in substantially lesser quantities. Xylitol, a five-carbon sugar polyol, has been found to be promising in reducing dental caries disease and also reversing the process of early caries. This paper throws light on the role and effects of various forms of xylitol on dental caries and oral hygiene status of an individual. PMID:25422590

Dental caries in the primary dentition in public nursery school children in Juiz de Fora, Minas Gerais, Brazil.  

PubMed

The aim of this study was to assess the prevalence of dental caries in the primary dentition and associated variables in low socioeconomic preschool children enrolled in public nursery schools in Juiz de Fora, Minas Gerais, Brazil. Four public institutions were selected by geographic criteria (two in the central region and two in the peripheral region). The study population comprised 338 children (181 boys; 157 girls) aged 2-6 years old. Dental caries was recorded using the decayed, missing, and filled teeth (dmf-t) index. Among the examined children, 50.6% were caries-free. The mean dmf-t index was 2.03. It was higher in the peripheral nursery schools (p<0.01). A trend towards a difference between sexes (p = 0.06) was observed. Logistic regression analysis selected a previous child's visit to dentist (p<0.001), geographic location of the public nursery school (p<0.01), and age (p<0.01) as predictive variables for the dmf-t index. The study showed the need for an oral health program for this population, including both curative and preventive measures in order to achieve the WHO/FDI goals for the year 2000, namely 50% of children free of caries at age 5-6 years.

Most cast dental restorations are made from alloys or commercially pure titanium (cpTi). Many orthodontic appliances are also fabricated from metallic materials. It has been documented in vitro and in vivo that metallic dental devices release metal ions, mainly due to corrosion. Those metallic components may be locally and systemically distributed and could play a role in the etiology of

Knowledge and attitudes of Saudi dental undergraduates on oral cancer.  

PubMed

Oral cancer awareness among future dental practitioners may have an impact on the early detection and prevention of oral cancer. A cross-sectional survey was undertaken to assess the current knowledge of future Saudi dentists on oral cancer and their opinions on oral cancer prevention. A pretested questionnaire was sent to 550 undergraduate dental students in the fourth, fifth, and sixth year of the Al-Farabi College for Dentistry and Nursing, Riyadh, Saudi Arabia. Questions relating to knowledge of oral cancer, risk factors, and opinions on oral cancer prevention and practices were posed. Four hundred seventy-nine students returned the questionnaire (87.1 %). Eighty-one percent of respondents correctly answered questions relating to oral cancer awareness. Eighty-seven percent of respondents felt confident in performing a systematic oral examination to detect changes consistent with oral malignancy. Interestingly, 57 % of respondents had seen the use of oral cancer diagnostics aids. Thirty-seven percent of respondents felt inadequately trained to provide tobacco and alcohol cessation advice. There is a need to reinforce the undergraduate dental curriculum with regards to oral cancer education; particularly in its prevention and early detection. Incorporating the use of oral cancer diagnostic aids should be made mandatory. PMID:24699922

Current trends in dental implants  

PubMed Central

Tooth loss is very a very common problem; therefore, the use of dental implants is also a common practice. Although research on dental implant designs, materials and techniques has increased in the past few years and is expected to expand in the future, there is still a lot of work involved in the use of better biomaterials, implant design, surface modification and functionalization of surfaces to improve the long-term outcomes of the treatment. This paper provides a brief history and evolution of dental implants. It also describes the types of implants that have been developed, and the parameters that are presently used in the design of dental implants. Finally, it describes the trends that are employed to improve dental implant surfaces, and current technologies used for the analysis and design of the implants. PMID:24868501

Dental cleaning before and during pregnancy among Maryland mothers.  

PubMed

Despite increasing recognition of the importance of oral health to overall health, dental care utilization remains low in the US. Given the established link between maternal oral health and child oral health, this study examined factors related to preventive dental care utilization at two critical time points, before and during pregnancy. Data were obtained from a sample of 6,171 women who delivered a live birth during 2004-2008 and completed the Maryland Pregnancy Risk Assessment Monitoring System postpartum survey. Multinomial logistic analyses examined associations between predisposing and enabling factors with dental cleaning before and during pregnancy. Women with less than a high school education or a history of physical abuse and non-Hispanic black and Hispanic women were less likely to report teeth cleaning before and during pregnancy. Having no insurance at the start of pregnancy was associated with significantly lower risk of teeth cleaning before pregnancy and both before and during pregnancy. Receipt of oral health counseling during pregnancy was positively related to teeth cleaning during pregnancy. Dental cleaning is associated with insurance, oral health counseling and maternal factors such as race, ethnicity, education and history of physical abuse. Better integration of oral health into prenatal health care, particularly among ethnic and racial minority groups, may be beneficial to maternal and infant well-being. Oral health promotion, disease prevention and health care should be a part of the local, state and national health policy agendas. PMID:22311579

Nanotechnology and Dental Implants  

PubMed Central

The long-term clinical success of dental implants is related to their early osseointegration. This paper reviews the different steps of the interactions between biological fluids, cells, tissues, and surfaces of implants. Immediately following implantation, implants are in contact with proteins and platelets from blood. The differentiation of mesenchymal stem cells will then condition the peri-implant tissue healing. Direct bone-to-implant contact is desired for a biomechanical anchoring of implants to bone rather than fibrous tissue encapsulation. Surfaces properties such as chemistry and roughness play a determinant role in these biological interactions. Physicochemical features in the nanometer range may ultimately control the adsorption of proteins as well as the adhesion and differentiation of cells. Nanotechnologies are increasingly used for surface modifications of dental implants. Another approach to enhance osseointegration is the application of thin calcium phosphate (CaP) coatings. Bioactive CaP nanocrystals deposited on titanium implants are resorbable and stimulate bone apposition and healing. Future nanometer-controlled surfaces may ultimately direct the nature of peri-implant tissues and improve their clinical success rate. PMID:21253543

Electronic dental anesthesia uses the Gate Control Theory of transcutaneous electrical nerve stimulation. The battery-controlled Ultracalm electronic dental anesthesia unit is a noninvasive procedure to electrically block pain transmissions in dental patients. This pilot study to test the efficacy of electronic dental anesthesia for simple restorative procedures was subjectively reported by 20 patients who had never been exposed to this type of anesthesia. None of the patients indicated the procedure was uncomfortable, and 14 of 20 subjects indicated that they preferred electronic dental anesthesia to local anesthetic injection. Electronic dental anesthesia appears to be an effective means of obtaining local anesthesia for certain dental procedures. PMID:8511275

Two unusual cases of dental (periapical) infection.  

PubMed

Cutaneous sinus tracts of dental origin are often a diagnostic challenge. A delay in correct diagnosis can result in inappropriate treatments. We describe two unusual cases of periapical infection. The first patient presented with a fistulized tumoral mass under the chin present for 1 year. The patient had only one tooth, and that was anatomically unrelated to the tumor. Radiological examination showed a dormant tooth that was infected periapically. The second case was a man who complained of asymmetry and change in his left nasolabial fold of 4-5 week's duration. On examination, the nasolabial folds were asymmetric without any sign of facial palsy. On intraoral examination, there was a severely decayed tooth on the same side. Radiological survey confirmed periapical infection. A few weeks after proper treatment, the nasolabial folds became symmetric. PMID:17083870

Oral Health Literacy and Oral Health Status among Adults Attending Dental College Hospital in India  

PubMed Central

Background: Low health literacy is one among many reasons why preventable diseases remain so common and why people often do not adopt healthy practices. It is important to detect patients with inadequate oral health literacy (OHL) and to improve the level of communication between the provider and the patient. This study was aimed to determine the relationship between OHL with selected socio-demographic variables and oral health status among adults in Virajpet, Karnataka, India. Materials and Methods: A convenience sample of 187 subjects from the out-patient department of Coorg-Institute of Dental Sciences Hospital administered the Rapid Estimate of Adult Literacy in Dentistry (REALD-30). The demographic variables and the oral health status were recorded for every participant using World Health Organization oral health survey proforma (1997). Data were analyzed using t-tests, analysis of variance, correlations and Kruskal–Wallis test. Results: The associations between REALD-30 scores and gender, age, and ethnicity were not statistically significant. Significant associations were found between REALD scores and the following oral-health related variables: Temperomandibular joint problems, prevalence of prosthetic need, CPI (Community Periodontal Index) and loss of attachment scores. REALD-30 scores were negatively correlated with DMFT (Decayed, Missing and Filled Teeth) scores and DAI (Dental Aesthetic Index) scores. Conclusion: OHL was not associated with sex, age, or ethnicity in this sample of the Virajpet population. OHL was associated with oral health status. Lower OHL was associated with poorer oral health status. OHL instruments can be considered to be included as screening tools to identifying individuals or groups with poor oral health outcomes.

The dental informatics online community.  

PubMed

Dental Informatics (DI) is the application of computer and information science to improve dental practice, research, education, and program administration. To support the growth of this emerging discipline, we created the Dental Informatics Online Community (DIOC). The DIOC provides a dedicated professional home for DI researchers and serves as an open, common, and worldwide forum for all individuals interested in the field. It was created and is maintained by the Center for Dental Informatics at the University of Pittsburgh School of Dental Medicine, independent from any professional association, corporate interest or funding source. The DIOC's Website provides many useful features, such as a learning center, publication archive, member and project directories, and the Current Awareness Service (CAS). The CAS automatically notifies members about new information added to the Community. Notifications are individualized according to a member's profile and activities on the site. The DIOC is a research-oriented online community which provides resources in the dental informatics and dental technology field, as well as a way to establish social connections to share ideas, problems and research opportunities. Member and activity growth since the community's inception in 2005 have been steady, but future sustainability of the community depends on many factors. PMID:21364841

[Dental spacing problems and associated factors among Brazilian adolescents].  

PubMed

The scope of this study was to estimate the prevalence of dental spacing problems and associated factors among adolescents using data from the SB Brazil 2010 survey. The outcomes evaluated were dental spacing problems: space deficit (crowding and misalignment) and excess space (diastema and spacing) obtained using the DAI index. The association of independent variables with outcomes was assessed using a hierarchical model with four levels: contextual, socioeconomic and demographic characteristics, access to services and dental morbidity. Statistical analysis was performed using the chi-square test and univariate and multivariate Poisson distribution to estimate prevalence ratios (PR). The overall prevalence of space problems was 71.43%, with misalignment being the most common type (56.4%). The following aspects were significantly associated with excess space: age of 16, 18 and 19 years; being non-Caucasian (PR = 1.75), perception of speech problems (PR = 1.72) and periodontal pockets 4-5mm (RP = 1.56). For space deficit: family income up to 3 minimum wages, dental visit 1 year or more previously (PR = 1.19) and having one or more decayed teeth on average (PR = 1.32). There was a prevalence of spacing problems, especially with socioeconomic and demographic variables and morbidity as potential risk factors. PMID:25351321

Surface modulation of dental hard tissues  

NASA Astrophysics Data System (ADS)

Tooth surfaces play a central role in the equilibrium of dental hard tissues, in which contrasting processes lead to loss or deposition of materials. The central interest of this Thesis was the modulation of tooth surfaces to control such equilibrium. Four specific studies were carried out to investigate different classes of surface modulating agents. These are: (1) Ionic modulation of the enamel surface to enhance stain removal . Dental stain is the most apparent form of tooth surface deposit. The nature of extrinsic stain in terms of spatial chemical composition was studied by using electron probe microanalysis. An ionic surface modulating agent, sodium tripolyphosphate (STPP), was evaluated. Image analysis methodologies were developed and the ability of STPP in stain removal was proved. (2) Thin film modulation with substantive polymeric coating and the effect on in vitro enamel de/re-mineralization . A novel polymeric coating that formed a thin film on the tooth surface was investigated for its inhibitory effect on artificial enamel caries, without interfering with the remineralization process. The preventive effect was distinct, but the mineral redeposition was questionable. (3) Thick film modulation with fluoride containing sealants and the effect on in vitro enamel and root caries development. Fluoride incorporated into resin material is an example of combining different classes of surface modulating agents to achieve an optimal outcome. A proper combination, such as in resin modified glass ionomer, showed in vitro caries inhibitory effect beyond the material boundary in both enamel and dentin. (4) Thick film modulation with dental adhesives and the determination of adhesion to dentin. Dentin adhesives modulate intracoronal tooth surfaces by enhancing adhesion to restorative materials. Conventional nominal bond tests were inadequate to determine the performance of current high strength adhesives. It was shown that interfacial fracture toughness test was more appropriate. In general, this Thesis evaluates diverse tooth surface modulations, for which several experimental methodologies had to be developed. These will be invaluable for the development of succeeding generations of surface modulating agents.

Assessment of tobacco dependence curricula in Italian dental hygiene schools.  

PubMed

The aim of this study was to assess the level of tobacco dependence education offered by Italian dental hygiene programs. A fifty-question survey was mailed to the thirty-one active public and private dental hygiene programs in Italy during the 2008-09 academic year. The survey assessed faculty confidence in teaching tobacco treatment, which courses contained tobacco dependence content, the number of minutes spent on specific content areas, and the level of clinical competence that dental hygiene graduates should be able to demonstrate. Surveys were returned by sixteen programs for a response rate of 52 percent. Respondents indicated tobacco dependence education was included in clinic or clinic seminar (56 percent), periodontics (44 percent), oral pathology (31 percent), and prevention (19 percent). All programs reported including the effects of tobacco on general and oral diseases in courses. However, more in-depth topics received less curriculum time; these included tobacco treatment strategies (63 percent) and discussion of cessation medications (31 percent). Interestingly, 62 percent of the respondents indicated they expected dental hygiene graduates to demonstrate a tobacco treatment competency level of a moderate intervention or higher (counseling, discussion of medications, follow-up) rather than a brief intervention in which patients are advised to quit then referred to a quitline. The results of this study indicated that Italian dental hygiene students are not currently receiving adequate instruction in tobacco treatment techniques nor are they being adequately assessed. This unique overview of Italian dental hygiene tobacco dependence education provides a basis for further discussion towards a national competency-based curriculum. PMID:23929577

Rural dentistry: Is it an imagination or obligation in community dental health education?  

PubMed Central

During the past two decades, epidemiologic studies in less developed or developing countries have clearly reported that caries prevalence shows the distinctive patterns over the word, even though it is declining in many developed countries. Due to huge rural districts where arrival is problematic and ineffective dental and preventive care centers in most suburban districts, there has been significant difference between the different parts of the communities to provide dental care service, and unfortunately the sole preventive measure has been limited with the advising of using the tooth brush and paste. The problems are usually arisen not only from the inadequacy of trained personnel but also from the absence of an effective economic and pragmatic system which aims to effectively dispense the dental service to all over the country. For this reason, the basic aim of dental care should be to carry out the many dental services in a multidisciplinary manner within the first appointment and to serve the people at their own homes and/or districts. Clearly, the needed multidisciplinary dental care system can lead to a new educational doctrine for rural dental practice. This versatile and practical training program based on specific perceived needs of a specific population(s) could need a new educational program. So, various preventive and/or restorative procedures included by this new doctrine could be named as “rural dentistry.” In this review, with the examples from the many in vivo studies carried out under rural conditions over the world, the probable practices in this specific dental doctrine have generally been exemplified.

Dental Arch Wire  

NASA Technical Reports Server (NTRS)

Straightening teeth is an arduous process requiring months, often years, of applying corrective pressure by means of arch wires-better known as brace-which may have to be changed several times in the course of treatment. A new method has been developed by Dr. George Andreasen, orthodontist and dental scientist at the University of Iowa. The key is a new type of arch wire material, called Nitinol, with exceptional elasticity which helps reduce the required number of brace changes. An alloy of nickel and titanium, Nitinol was originally developed for aerospace applications by the Naval Ordnance Laboratory, now the Naval Surface Weapons Laboratory, White Oaks, Maryland. NASA subsequently conducted additional research on the properties of Nitinol and on procedures for processing the metal.

Dental insurance! Are we ready?  

PubMed

Dental insurance is insurance designed to pay the costs associated with dental care. The Foreign Direct Investment (FDI) bill which was put forward in the winter session of the Lok Sabha (2008) focused on increasing the foreign investment share from the existing 26% to 49% in the insurance companies of India. This will allow the multibillion dollar international insurance companies to enter the Indian market and subsequently cover all aspects of insurance in India. Dental insurance will be an integral a part of this system. Dental insurance is a new concept in Southeast Asia as very few countries in Southeast Asia cover this aspect of insurance. It is important that the dentists in India should be acquainted with the different types of plans these companies are going to offer and about a new relationship which is going to emerge in the coming years between dentist, patient and the insurance company.

Osseointegrated dental implants produced via microwave processing  

NASA Astrophysics Data System (ADS)

This research is a comprehensive effort to develop osseointegrated dental implants via microwave processing. A net-shape microwave sintering procedure was employed to fabricate dental implants. Commercial pure titanium powders (-100, -200 and -325 mesh sizes) were used in this work. This process eliminates the need for machining of implants and prevents contamination. The idea was to take advantage of the peculiar way microwave couple with metallic powders, i.e. generating heat in the interior of the sample and dissipating it away through the surface. The desired features for an implant, a dense core with surface pores, is not possible via conventional sintering. Coating with hydroxyapatite via electrodeposition and chemical combustion vapor deposition was also attempted to further enhance the bioactivity of this layer. Surface roughness and area were measured using a non-contact surface profilometer to further describe the unique surface. In-vitro studies, conducted using osteoblast cells extracted from neonatal rat calvarial, showed improved cell growth on all the uncoated porous samples. However, the highest cell growth was observed on the -200 mesh size samples. The higher surface area of the -200 mesh samples is attributed to this observation. This work was able to identify the processing parameters for titanium in microwave and establishes the importance of surface area as a key parameter for cell growth on porous surfaces as compared to surface roughness.

Degradation, fatigue and failure of resin dental composite materials  

PubMed Central

The intent of this article is to review the numerous factors that affect the mechanical properties of particle or fiber filler containing, indirect dental resin composite materials. The focus will be on degradation due to aging in different media, mainly water and water and ethanol, cyclic loading, and mixed mode loading on the flexure strength and fracture toughness. Next several selected papers will be examined in detail with respect to mixed and cyclic loading and then an examination of 3D tomography using multiaxial compression specimens. The main cause of failure, for most dental resin composites, is the breakdown of the resin matrix and or the interface between the filler and the resin matrix. In clinical studies, it appears that failure in the first 5 years is a restoration issue (technique or material selection) and after that time period from secondary decay. PMID:18650540

Comparative Effectiveness Study to Assess Two Examination Modalities Used to Detect Dental Caries in Preschool Urban Children  

PubMed Central

Abstract Background: Dental caries affecting the primary dentition of U.S. children continues to be the most prevalent chronic childhood disease. Preventive screening for dental caries in toddlers by dental professionals is labor-intensive and costly. Studies are warranted to examine innovative screening modalities that reduce cost, are less labor-intensive, and have the potential to identify caries in high-risk children. Subjects and Methods: Two hundred ninety-one children were randomized into two groups: Group 1 received a traditional, visual tactile examination initially and follow up-examinations at 6 and 12 months, and Group 2 received a teledentistry examination initially and follow-up examinations at 6 and 12 months. The mean primary tooth decayed and filled surfaces (dfs) scores were calculated for all children at baseline and 6 and 12 months. Results: At baseline, the mean dfs score for children examined by means of teledentistry was 2.19, and for the children examined by means of the traditional method, the mean was 1.27; the means were not significantly different. At the 12-month examination, the mean dfs score for the children examined by means of teledentistry was 3.02, and for the children examined by means of the clinical method, the mean dfs was 1.70; the means were not significantly different. At 12 months the mean fillings score for the children examined by means of teledentistry was 1.43 and for the children examined by means of the clinical method was 0.51; the means were statistically significantly different (p<0.001). Conclusions: These results suggest that the teledentistry examinations were comparable to clinical examinations when screening for early childhood caries in preschool children. The data further showed that color printouts of teeth with cavities provided to parents of children who received teledentistry screenings promoted oral healthcare utilization, as children from the teledentistry study group received more dental care than children from the clinical study group.

Effects of dental trauma on the pulp.  

PubMed

Infection of the root canal system following dental trauma induces pulp and periapical disease and prevents healing of previously healthy pulp. A clinical goal in treating trauma is the maintenance of pulp vitality, and clinicians should be aware of factors that influence pulp healing. The learning objective of this article is to review the factors and techniques that influence pulp vitality and examine the influence pulp has on the healing of adjacent tissues. The potential routes for bacterial infection of the root canal system are discussed, with the clinical crown as the primary portal of entry. Uncomplicated and complicated crown fractures, as well as the crown-root and root fractures, are reviewed. Complications in pulp healing include canal obliteration, disturbed root development, apexogenesis, apexification, and the various forms of resorption. PMID:9550069

Little is known about the characteristics of cutaneous sinus tract (CST) of dental origin in children. 28 cases of CST of dental origin in children were evaluated. Age, sex, site of skin lesion, duration until diagnosis, teeth involved, etiology, treatment, and outcome were recorded. The last dental care visit was also recorded. The mean age was 10.25 years (range 4-16). The male to female ratio was 1:1.74. The mandibular-submandibular area was the most common site of skin lesions. The mandibular first molar was the most involved tooth, followed by the mandibular incisor. Caries was the most common etiology. The mean duration of lesions until correct diagnosis was 6.5 months (range 0.3-12 mos). The treatment was root canal therapy or extraction. After appropriate dental treatment, CSTs resolve rapidly. Surgical revision of the scars were indicated in eight (29%) patients, to provide better cosmetic results. In these patients, the duration of lesions were longer. Preventive dental care, as indicated by last dental care visit, was poor. CST in children is different from that in adults in terms of sites of skin lesions, duration of lesions, and involved tooth and similar to that in adults in terms of etiology and treatment modality. Early treatment of the dental infection may cause healing of the cutaneous lesion spontaneously, without a scar. PMID:22329589

Residency training in dental public health: assessment of status, needs, and issues.  

PubMed

The opportunities for public health training have declined over the years while the need for public health skills is likely to increase. This paper reports the results of a project, sponsored by the Health Resources and Services Administration, which answers the question of "how best to invest in the dental public health education system so as to fulfill the profession's responsibilities to protect and improve the oral health of individuals and society." An information base on dental public health education, practice, and specialization was developed from an extensive review of the literature and a survey of dentists concerning employment and practice requirements for public health dentists. An advisory group considered this information, met to discuss the issues involved in dental public health training, and provided advice to the project staff. Based on the information gathered as part of the project, recommendations were made to: (1) develop a grant program to support advanced education in dental public health; (2) increase the competencies of dentists who are working in public health positions and not eligible for board certification via off-site residencies; (3) develop model programs in areas of great need, such as general public health, management, policy, prevention, environmental health and research, that in conjunction with a basic public health core, could satisfy the eligibility requirements of the American Board of Dental Public Health; (4) develop student loan forgiveness programs for dentists and dental hygienists working in public health; and (5) develop additional credential recognition programs for dental public health workers.

Effect of year of study on stress levels in male undergraduate dental students  

PubMed Central

Objective Stress among dental students can be a significant threat, resulting in physical and/or mental illness, and have a negative effect on students’ performance and the professional practice of dentistry. Stress can occur from different sources. The purpose of this study is to test whether the year of study has an effect on the stress levels of dental students. Method Our study consisted of a cross-sectional survey using a modified version of the Dental Environment Stress (DES) questionnaire. The questionnaires were filled out by male undergraduate dental students at King Saud University in Riyadh City during the 2010–2011 academic year (n = 214). Results The results show the most common sources of stress: examinations and completing clinical requirements. Moreover, in the five-year lecture-based traditional curriculum, the third year students reported the highest level of stress, whereas the first year reported the lowest level of stress. Conclusion Third year undergraduate dental students reported the highest level of stress. This stress could be reduced by reviewing and modifying the dental curriculum by allowing students to have contact with patients more gradually, starting from the first year, in addition to adding stress prevention and intervention programs in dental curricula.

Minimal intervention dentistry for managing dental caries - a review: report of a FDI task group.  

PubMed

This publication describes the history of minimal intervention dentistry (MID) for managing dental caries and presents evidence for various carious lesion detection devices, for preventive measures, for restorative and non-restorative therapies as well as for repairing rather than replacing defective restorations. It is a follow-up to the FDI World Dental Federation publication on MID, of 2000. The dental profession currently is faced with an enormous task of how to manage the high burden of consequences of the caries process amongst the world population. If it is to manage carious lesion development and its progression, it should move away from the 'surgical' care approach and fully embrace the MID approach. The chance for MID to be successful is thought to be increased tremendously if dental caries is not considered an infectious but instead a behavioural disease with a bacterial component. Controlling the two main carious lesion development related behaviours, i.e. intake and frequency of fermentable sugars, to not more than five times daily and removing/disturbing dental plaque from all tooth surfaces using an effective fluoridated toothpaste twice daily, are the ingredients for reducing the burden of dental caries in many communities in the world. FDI's policy of reducing the need for restorative therapy by placing an even greater emphasis on caries prevention than is currently done, is therefore, worth pursuing. PMID:23106836

Antibiotics in dental practice: how justified are we.  

PubMed

Antibiotics are prescribed by dentists in dental practice, during dental treatment as well as for prevention of infection. Indications for the use of systemic antibiotics in dentistry are limited because most dental and periodontal diseases are best managed by operative intervention and oral hygiene measures. The use of antibiotics in dental practice is characterised by empirical prescription based on clinical and bacteriological epidemiological factors, resulting in the use of a very narrow range of broad-spectrum antibiotics for short periods of time. This has led to the development of antimicrobial resistance (AMR) in a wide range of microbes and to the consequent inefficacy of commonly used antibiotics. Dentists can make a difference by the judicious use of antimicrobials - prescribing the correct drug, at the standard dosage and appropriate regimen - only when systemic spread of infection is evident. The increasing resistance problems of recent years are probably related to the over- or misuse of broad-spectrum agents. There is a clear need for the development of prescribing guidelines and educational initiatives to encourage the rational and appropriate use of drugs in dentistry. This paper highlights the need for dentists to improve antibiotic prescribing practices in an attempt to curb the increasing incidence of antibiotic resistance and other side effects of antibiotic abuse. The literature provides evidence of inadequate prescribing practices by dentists for a number of factors, ranging from inadequate knowledge to social factors. PMID:25510967

A review of the dental caries status of ethnic minority children in china.  

PubMed

China has 55 ethnic minority groups comprised of 113 million persons, or 7.0 % of total population. Dental caries is a major health problem for children in China, and national oral health surveys currently report dental caries based on geographical location rather than by ethnic group. This study reviews the literature on dental caries in ethnic minority children in China. Publications were retrieved in Chinese and English from five electronic databases; thirty-eight studies from 1983 to 2012 met inclusion criteria and described 25 ethnic minority groups. Primary dentition median caries prevalence and experience were higher (51 % and dmft = 3.0, respectively) than permanent dentition caries prevalence and experience (39 % and DMFT = 0.8). Median caries prevalence was highest (80 %) for permanent dentition among aggregated ethnic minorities with population greater than 1 million. More work and research is needed to expand dental caries prevention and treatment measures for ethnic minority child populations in China. PMID:24057753

[Dental care in case of head and neck cancer--Part I: Radiotherapy].  

PubMed

The dental care because of radiotherapy in case of head and neck cancer should be practiced by skilled dentists. First the residual teeth and the dental restorations have to be cleaned and controlled very well. Radiographs complete examinations. Necessary extractions should consider the later prosthodontic restoration with regard to the financial situation of the patient. Mucosal distractors also useful for fluoridation of the teeth and spreader preventing areas which have not necessarily to be irradiated can be manufactured by the dentist. During irradiation the dentist can help to keep up good oral hygiene. After irradiation a close monitoring may avoid dental destruction and osteoradionecrosis of the jaws. The dentist should recommend strategies to moderate xerostomia and he can subscribe lymphodrainage if necessary. He can survey the opening of the mouth and the fluoridation of the teeth to limit irradiation caries and osteoradionecrosis. In the end the dentist has to reestablish esthetics, phonetics and chewing function by manufacturing dental restorations. PMID:19031347

Oral Health Disparities and Unmet Dental Needs among Preschool Children in Chelsea, MA: Exploring Mechanisms, Defining Solutions  

PubMed Central

Background Significant disparities exist in children’s receipt of preventive dental care (PDC) in the United States. Many of the children at greatest risk of dental disease do not receive timely PDC; when they do receive dental care, it is often more for relief of dental pain. Chelsea is a low-income, diverse Massachusetts community with high rates of untreated childhood caries. There are various dental resources available in Chelsea, yet many children do not access dental care at levels equivalent to their needs. Objective Using Chelsea as a case-study, to explore factors contributing to forgone PDC (including the age 1 dental visit) in an in-depth way. Methods We used a qualitative study design that included semi-structured interviews with parents of preschool children residing in Chelsea, and Chelsea-based providers including pediatricians, dentists, a dental hygienist and early childhood care providers. We examined: a) parents’ dental attitudes and oral health cultural beliefs; b) parents’ and providers’ perspectives on facilitators and barriers to PDC, reasons for unmet needs, and proposed solutions to address the problem. We recorded, transcribed and independently coded all interviews. Using rigorous, iterative qualitative data analyses procedures, we identified emergent themes. Results Factors perceived to facilitate receipt of PDC included Head-Start oral health policies, strong pediatric primary care/dental linkages, community outreach and advertising, and parents’ own oral health experiences. Most parents and providers perceived there to be an adequate number of accessible dental services and resources in Chelsea, including for Medicaid enrollees. However, several barriers impeded children from receiving timely PDC, the most frequently cited being insurance related problems for children and adults. Other barriers included limited dental services for children <2 years, perceived poor quality of some dental practices, lack of emphasis on prevention-based dental care, poor care-coordination, and insufficient culturally-appropriate care. Important family-level barriers included parental oral health literacy, cultural factors, limited English proficiency and competing priorities. Several solutions were proposed to address identified barriers. Conclusion Even in a community with a considerable number of dental resources, various factors may preclude access to these services by preschool-aged children. Opportunities exist to address modifiable factors through strategic oral health policies, community outreach and improved care coordination between physicians, dentists and early childhood care providers.

Experiences of Dental Care and Dental Anxiety in Adults with Autism Spectrum Disorder  

PubMed Central

Dental anxiety is associated with previous distressing dental experiences, such as lack of understanding of the dentist intentions, perceptions of uncontrollability and experiences of pain during dental treatment. People with autism spectrum disorder (ASD) are impaired in building flexible predictions and expectations, which is very much needed during a dental visit. The aims of the study were to investigate if people with ASD have more negative dental experiences and a higher level of dental anxiety compared to a matched control group. Forty-seven adults with ASD and of normal intellectual performance, and 69 age- and sex-matched typically developing controls completed questionnaires on previous dental experiences and dental anxiety, the Dental Anxiety Scale, and the Dental Beliefs Survey. The ASD group experienced pain during dental treatments more often than the controls and 22% had repeatedly experienced being forced to dental treatment they were not prepared for, compared to 3% of the controls. A higher level of dental anxiety was reported by the ASD group. Dental treatment and methods for supporting the communication with patients with ASD need to be developed, in order to reduce the negative dental experiences and dental anxiety in people with ASD.

Sealants and dental caries  

PubMed Central

Background The authors conducted a qualitative study of private-practice dentists in their offices by using vignette-based interviews to assess barriers to the use of evidence-based clinical recommendations in the treatment of noncavitated carious lesions. Methods The authors recruited 22 dentists as a convenience sample and presented them with two patient vignettes involving noncavitated carious lesions. Interviewers asked participants to articulate their thought processes as they described treatment recommendations. Participants compared their treatment plans with the American Dental Association’s recommendations for sealing noncavitated carious lesions, and they described barriers to implementing these recommendations in their practices. The authors recorded and transcribed the sessions for accuracy and themes. Results Personal clinical experience emerged as the determining factor in dentists’ treatment decisions regarding noncavitated carious lesions. Additional factors were lack of reimbursement and mistrust of the recommendations. The authors found that knowledge of the recommendations did not lead to their adoption when the recommendation was incongruent with the dentist’s personal experience. Conclusions The authors found that ingrained practice behavior based on personal clinical experience that differed substantially from evidence-based recommendations resulted in a rejection of these recommendations. Practical Implications Attempts to improve the adoption of evidence-based practice must involve more than simple dissemination of information to achieve a balance between personal clinical experience and scientific evidence.

Tobacco Cessation Counselling Practices and Attitude among the Dentist and the Dental Auxiliaries of Urban and Rural Areas of Modinagar, India  

PubMed Central

Background: The increasing use of tobacco among youths warrants the need for dental health professionals to effectively provide tobacco cessation counselling (TCC) in the office and community settings. However, there have been concerns among the dental professionals regarding TCC in dental settings. Aims and Objectives: To assess the attitude of dental professionals including the dentist and dental hygienist towards the TCC and identify the possible barriers towards the implementation of these practices in the rural and urban areas of Modinagar district. Materials and Methods: The present questionnaire based survey was carried among the qualified dentist and dental hygienist from the urban and rural areas of the Modinagar district to attitudes in tobacco cessation, practices in tobacco cessation interventions and related barriers towards implementation. The survey data were analyzed using the SPSS 16 version software package. The descriptive statistics (frequency) was generated for the each question to assess their attitude and practice. Results: The response rate of the questionnaire among the dentist and dental hygienist was 100%. The attitude of the majority of dentist towards the tobacco cessation counselling was positive as compared to the dental hygienist. 69.2% of the dentist were of the view that the dental health professionals should provide TCC as compared to 54.2% among the hygienist. Regarding the practice, only 12.5% and 5.8% of the dentist and dental hygienist had ever used the nicotine replacement therapy in their dental practice. The lack of the knowledge and information regarding TCC was the only perceived barrier among the dentists (51.7%) and dental hygienist (68.3%). Conclusion: Dental professionals must expand their horizon and armamentarium to include TCC strategies inclusive of their regular preventive and therapeutic treatment modalities. Also, the dental institutions should include TCC into the curriculum, but it should not be just theoretical knowledge rather it must have a practical component. PMID:25386513

Zirconia dental implants: a literature review.  

PubMed

Titanium and titanium alloys are widely used for fabrication of dental implants. Because of potential immunologic and possible esthetic compromises with titanium implants, novel implant technologies are being developed. However, these novel technologies must maintain the characteristics that provide titanium implants with their high success rates. Zirconia implants were introduced into dental implantology as an alternative to titanium implants. Zirconia seems to be a suitable implant material because of its toothlike color, mechanical properties, biocompatibility, and low plaque affinity. The aim of this study is to review clinical and research articles conducted on zirconia dental implants, compare them with titanium dental implants, and provide information on zirconia dental implant osseointegration and mechanical strength. Zirconia dental implants have the potential to become alternative dental implants to titanium dental implants, but they are not yet in routine clinical use. PMID:20545529

In 2013, a dental practice without a website is almost unthinkable. Using a sample of309 dentists drawn from the list of members of the Dutch Dental Association in 2012, a study was carried out to find out whether the dental practice of the general dental practitioner had a website. The content of each website was subsequently inventoried using a questionnaire. Eighty-nine percent of the dental practices had a website. The content of the websites, however, varied enormously. An element such as the professional registration number with a reference to the professional register were absent in 73% of the websites and the date of the most recent update of the website was mentioned only once. The name of the dentist, his or her professional qualification and an email address were missing on respectively 9%, 20% and 9% of the websites. Contracts of the practice with insurance companies were rarely clearly indicated. The websites of many practices would benefit considerably from a significant improvement. PMID:24881254

Dental surgery in ancient Egypt.  

PubMed

Many different surgical procedures have over the years been attributed to the ancient Egyptians. This is also true regarding the field of dental surgery. The existence of dentists in ancient Egypt is documented and several recipes exist concerning dental conditions. However, no indications of dental surgery are found in the medical papyri or in the visual arts. Regarding the osteological material/mummies, the possible indications of dental surgery are few and weak. There is not a single example of a clear tooth extraction, nor of a filling or of an artificial tooth. The suggested examples of evacuation of apical abscesses can be more readily explained as outflow sinuses. Regarding the suggested bridges, these are constituted of one find likely dating to the Old Kingdom, and one possibly, but perhaps more likely, dating to the Ptolemaic era. Both seem to be too weak to have served any possible practical purpose in a living patient, and the most likely explanation would be to consider them as a restoration performed during the mummification process. Thus, while a form of dentistry did certainly exist in ancient Egypt, there is today no evidence of dental surgery. PMID:24665522

Preventing the Preventable  

PubMed Central

Objectives Growing literature suggests that a significant proportion of rehospitalizations could be prevented if systems were put in place aimed at identifying and addressing some of the underlying issues that cause them. This article highlights key risk factors for unplanned rehospitalizations and illustrates a project that has successfully addressed many of the underlying issues that contribute to them. Primary Practice Setting(s) The study illustrated herein took place at an inner-city academic teaching hospital. Findings/Conclusions Proactively identifying patient-, clinician-, and system-associated barriers to successful discharge transitions is critical for effective transitions of care for patients leaving the hospital setting. This process represents a culture change, requires a multidisciplinary approach to care, and mandates clear delineation of roles and responsibilities in the process, with ultimate and clear process ownership being defined. With such steps in place in a system of care, it is reasonable to expect a reduction in preventable rehospitalizations. PMID:19474639

Reforming the mission of public dental services.  

PubMed

Australia has a complex history of providing public dental services to its communities. From the early days of Colonial settlement, the provision of dental care to the Australian public has largely been driven and influenced by organized groups and associations of dentists. The Constitution of Australia, under Section 51 xxiii A, allows for the Commonwealth to provide for medical and dental services. Unlike the United Kingdom, however, dental services have not been embedded into a universal national health service agenda. In 1974, that the Australian Government through the Australian School Dental Program provided the first funding and national direction for public dental services - and that, limited to children. The Commonwealth Dental Health Program 1993-1997 was the second national endeavor to provide public dental services, this time to financially disadvantaged adults. Since that time, public dental service responsibility has been shuttled between States/Territories and the Commonwealth. A new paradigm for public dental services in Australia requires strong Commonwealth leadership, as well as the commitment of State and Territories and the organized dental profession. The National Health and Hospitals Reform Commission provided the most recent scenario for a radical change in mission. This paper canvases the competing roles of strategic, functional, and structural issues in relationship to social network and policy issues, which must be recognized if Australians truly seek to reform public dental services.

Assessing oral cancer knowledge in Romanian undergraduate dental students.  

PubMed

The aim of this study is to investigate the level of Romanian dental students' knowledge regarding the oral cancer risk and non-risk factors as well as oral cancer signs, symptoms, and diagnostic signs. A total of 192 first- to sixth-year undergraduate dental students (mean age 22.20?±?2.94 years) who consented to participate in the study filled in a questionnaire enquiring about their knowledge of oral cancer. A score of the oral cancer knowledge was calculated for each participant based on their correct answers. Regarding the knowledge of oral cancer risk factors, the vast majority of the students correctly recognized tobacco (96.8 %), having a prior oral cancer lesion (85.1 %), the consumption of alcohol (77.7 %), and older age (64.2 %). Respectively, 87.7 and 54.3 % knew the tongue and the floor of mouth to be the most common oral cancer sites. Of the students, 71.3 % agreed that oral cancer examinations for those 20 years of age and older should be provided during regular periodic health examinations, 92.9 % considered that patients with suspicious oral lesions should be referred to specialists, and 84.6 % agreed that oral cancer examinations should be a routine part of a comprehensive oral examination. A significant association was found between the year of study in the dental school, age, and knowledge of the oral cancer knowledge scores. Although students' knowledge increased with academic year, there is a clear need to enhance the dental curricula in oral cancer clinical training in oral cancer prevention and examination for dental students.

Micro-educational opportunities in outreach clinical dental education.  

PubMed

Outreach education at the University of Portsmouth Dental Academy is providing a valuable platform to offer students 'micro-educational opportunities'. Some of these are highly innovative experiences, which allow senior students across the dental team to take short periods of time away from the clinic to broaden their life experience. The maturity of senior students generates a significant added-value to their educational experiences with minimal loss of clinical time. Another important outcome, which echoes the Marmot review on Health Inequalities (2010), is the population of the City of Portsmouth, particularly the socially deprived, gain better access to oral health advice, prevention and treatment. Our experience suggests these opportunities enhance the undergraduate experience, equipping our new colleagues for a professional life in a changing and challenging environment. PMID:24157758

An Anthropological Perspective: Another Dimension to Modern Dental Wear Concepts  

PubMed Central

For many years, research on tooth wear by dental academics has been diametrically opposite to that of anthropological research, with each discipline having a different understanding as to the nature of the wear processes. Dental focus revolved around preventive and restorative considerations while the anthropological focus was a biological understanding related to human evolution, diet, environment, form, and function and included all the craniofacial structures. Introducing the anthropological perspective into modern dentistry gives an insight into the “bigger picture” of the nature and extent of tooth wear. By combining anthropological evidence with clinical knowledge and experience, it is most likely to provide the best-informed and biologically based approach to the management of tooth wear in modern societies.

Health literacy, acculturation, and the use of preventive oral health care by Somali refugees living in massachusetts.  

PubMed

This study investigated the impact of English health literacy and spoken proficiency and acculturation on preventive dental care use among Somali refugees in Massachusetts. 439 adult Somalis in the US ?10 years were interviewed. English functional health literacy, dental word recognition, and spoken proficiency were measured using STOFHLA, REALD, and BEST Plus. Logistic regression tested associations of language measures with preventive dental care use. Without controlling for acculturation, participants with higher health literacy were 2.0 times more likely to have had preventive care (P = 0.02). Subjects with higher word recognition were 1.8 times as likely to have had preventive care (P = 0.04). Controlling for acculturation, these were no longer significant, and spoken proficiency was not associated with increased preventive care use. English health literacy and spoken proficiency were not associated with preventive dental care. Other factors, like acculturation, were more predictive of care use than language skills.

Prevalence of dental caries among school children of Bharatpur city, India  

PubMed Central

Background: Healthy teeth and oral tissues and the need for oral health care are important for any section of society. Dental caries is an infectious microbial disease of multifactorial origin in which diet, host, and microbial flora interacts over a period of time in such a way so as to encourage demineralization of the tooth enamel with resultant caries formation. Dental caries, the product of man's progress towards civilization, has a very high morbidity potential and thus, is coming into focus of the mankind. Aims and Objectives: To assess the prevalence of dental caries among 12-15 year old government and private school children of Bharatpur city. Materials and Methods: This was a cross-sectional study carried out on total 1400 school children, of which 700 school children were from government schools and 700 were from private schools. Simple random sampling methodology was used to select the sample. The subjects were examined for dental caries according to WHO 1997 assessment form. Significant Caries Index was also used to assess the prevalence of dental caries. Results: The prevalence of dental caries was found higher among government school children, that is, 53%, when compared to private school children, that is, 47% and this difference was found to be statistically significant. The mean decayed, missing, and filled teeth were found to be higher in government school children (7.61 ± 2.86) as compared to private school children (4.76 ± 2.42). Conclusion: Dental caries was found to be the major public health problems among both the government and private school children of Bharatpur city, which need immediate attention. Regular dental checkups and practice of routine oral hygiene procedures will enable them to lead a healthier life. PMID:24818096

Nanomaterials in preventive dentistry  

NASA Astrophysics Data System (ADS)

The prevention of tooth decay and the treatment of lesions and cavities are ongoing challenges in dentistry. In recent years, biomimetic approaches have been used to develop nanomaterials for inclusion in a variety of oral health-care products. Examples include liquids and pastes that contain nano-apatites for biofilm management at the tooth surface, and products that contain nanomaterials for the remineralization of early submicrometre-sized enamel lesions. However, the treatment of larger visible cavities with nanomaterials is still at the research stage. Here, we review progress in the development of nanomaterials for different applications in preventive dentistry and research, including clinical trials.

Dental fear and anxiety in older children: an association with parental dental anxiety and effective pain coping strategies  

PubMed Central

An association between dental fear and anxiety (DFA) has been confirmed for children younger than 8 years, but this association in older children is less clear. The aim of this study was to fill this knowledge gap by studying DFA in older children and their parents with validated measures. This cross-sectional study, conducted at Community Health Centre Mostar, Bosnia and Herzegovina, included 114 children and their parents. DFA, coping, and sociodemographic variables were studied using Corah Dental Anxiety Questionnaire (CDAS), Dental Subscale of the Children’s Fear Survey Schedule (CFSS-DS), Dental Cope Questionnaire, and sociodemographic questionnaire. Maternal CDAS scores had significant positive correlation with child DFA measured with CFSS-DS (r=0.35, P<0.001) and CDAS (r=0.32, P<0.001). Fathers’ CDAS scores were not associated with child CFSS-DS, but showed a moderate correlation with child CDAS (r=0.19, P<0.05). There were no significant differences in children’s fear and anxiety based on age, sex, or socioeconomic variables. Children used internal coping strategies most frequently and external coping strategies were rated by the children as the most effective. We did not find differences in number and type of effective coping strategies in children with high DFA compared with children with low DFA. In conclusion, there is evidence of the coexistence of dental fear in parents and older children. These findings may help to devise interventions that will prevent or alleviate children’s DFA.

Oral health status, dental treatment needs, and barriers to dental care of elderly care home residents in Lodz, Poland  

PubMed Central

Objectives To determine oral health status, dental treatment needs, and to identify barriers that prevent easy access to dental care by elderly care home residents in Lodz. Background Studies in many countries show that oral health status of elderly care home residents is poor and there is an urgent need to improve it. Methods The study included 259 care home residents, aged 65 years and older. The oral examination was performed. In face-to-face interviews, subjects were asked about frequency of cleaning teeth and/or dentures, whether they needed assistance, and whether the assistance was available; they were also asked about the perceived dental needs, and about the time since their last visit to a dentist and the purpose of the visit. If they had not visited the dentist in the past 12 months, they were asked about reasons for failing to visit the dentist. Results Forty-six percent of the subjects were edentulous. Only 5.8% of all participants had a sufficient number of functional natural teeth. Dental treatment was found to be necessary in 59.8% of the respondents. One in four subjects reported reduced ability of correctly cleaning teeth and dentures themselves, of whom only one-third were helped by others. An insufficient level of hygiene was found in every other subject. About 42% of residents had not visited a dentist for over 5 years, mainly due to organizational reasons. Conclusion Expanding the current scope of medical care for the elderly care home residents to include dental care would improve their currently poor oral health status. PMID:25284997

PubMed Central

Aim: The aim of this study is to determine the prevalence of dental caries in primary teeth among 4-6 years old school going children in the Namakkal District. Materials and Methods: The study covered a total of 850 school going children in a total of 26 schools in the Namakkal district of Tamil Nadu. The age group selected for this study ranged from 4 to 6 years of age. Each child was examined in their respective schools by one of the four calibrated examiners and decay, missing and filled teeth (dmft) index was recorded along with demographic details. This study was done in September-October 2013 in a span of 1 month duration. Results: Of 850 children examined, 560 (65.88%) children had dental caries. Mean dmft score was 2.86. Prevalence of dental caries was higher in boys (69.6%) than in girls (61.5%). The untreated decay teeth accounted for 92.4%. Conclusion: The prevalence of dental caries among 4-6 years old children is high in the Namakkal district. The need for the creation of dental awareness among children and their primary caregivers is crucial and the need for developing immediate oral health promotion strategies including an increase in school dental health programs is recommended.

Osseointegrated dental implants in growing children: a literature review.  

PubMed

Edentulism is usually associated with the aging patient. However, total or partial tooth loss also affects young individuals, mainly as a result of trauma, decay, anodontia, or congenital and acquired jaw defects involving the alveolar processes. For elderly patients, the use of oral implants has become an accepted treatment modality for edentulism, and most of today's knowledge regarding implants is based on such practice. There has been hesitation to perform implant therapy for growing children; hence, few children to date have been provided with implant-supported construction. Consequently, little is known about the outcome of the osseointegration procedure in young patients, and until now, only a limited number of case presentations have been reported. This article reviews the current literature to discuss the use of dental implants in growing patients and the influence of maxillary and mandibular skeletal and dental growth on the stability of those implants. The literature review was performed through Science Direct, Wileys Blackwell Synergy, PubMed, Google, Embase, Medknow publications, and Springer for references published from 1963 to 2011. It is recommended to wait for the completion of dental and skeletal growth, except for severe cases of ectodermal dysplasia. PMID:22214484

Nutrition and health: guidelines for dental practitioners.  

PubMed

Good nutrition is vital to overall health, and poor diet and a sedentary lifestyle are major causes of morbidity and mortality worldwide. Nutritional factors are implicated in many oral and systemic diseases and conditions, including obesity, hypertension, dyslipidemia, type II diabetes, cardiovascular disease, osteoporosis, dental caries and some cancers including oral cancers. This review focuses on the evidence for the relations between key nutritional factors and health. Energy intake is related to body weight and obesity, highlighting the importance of lower-energy diets and regular physical activity for body weight maintenance and for preventing obesity. Evidence is presented for the health benefits of high quality carbohydrates, such as whole grain products, and fruits and vegetables, in reducing the risk of cardiovascular disease and cancer. The adverse effects of sugar, sweetened beverages, and trans and saturated fats on several diseases including caries, diabetes and cardiovascular disease are described. The health benefits of unsaturated fats, antioxidants, B vitamins and vitamin D in cardiovascular disease, periodontitis, cancer, and other conditions are documented. Both benefits and harmful effects of dairy product intake on health are discussed. Based on the evidence, nutritional guidelines are provided, as well as key recommendations for preventing obesity. Dentists can play a critical role in motivating and enabling healthy food choices. PMID:19467151

Mineralization Potential of Polarized Dental Enamel  

PubMed Central

Background Management of human teeth has moved from a surgical to a more conservative approach of inhibiting or preventing lesion progression. Increasing enamel mineralization is crucial in this regard. A potential difficulty is the preferential mineralization of the outermost portion of the enamel that can prevent overall mineralization. We describe a strategy for increasing the mineralization potential of dental enamel. Methodology/Principal Findings Extracted human premolar teeth enamel (n?=?5) were exposed to a high concentration of hydrogen peroxide with an energizing source. Samples were stored in artificial saliva at 37°C for 1 wk. A desktop X-ray micro-CT system was used to evaluate the mineral density of samples. Mineral distribution was polarized between the lower and the higher mineralized portion of enamel by charged oxygen free radicals due to activation of permeated hydrogen peroxide. The kinetics of energy absorption in the deeper enamel region demonstrated improvement of preferential mineralization into the region without restricting overall mineralization of the enamel. Subsequent increasing mineralization, even in the dense mineralized outer portion of enamel, was also achieved. Conclusions/Significance This increased mineralization may promote resistance to acidic deterioration of the structure. The present study is one of the primary steps towards the development of novel application in reparative and restorative dentistry. PMID:19543391

Socioeconomic and psychosocial predictors of dental healthcare use among Brazilian preschool children  

PubMed Central

Background Disparities in utilization of oral healthcare services have been attributed to socioeconomic and individual behavioral factors. Parents’ socioeconomic status, demographics, schooling, and perceptions of oral health may influence their children’s use of dental services. This cross-sectional study assessed the relationships between socioeconomic and psychosocial factors and the utilization of dental health services by children aged 1–5 years. Methods Data were collected through clinical exams and a structured questionnaire administered during the National Day of Children’s Vaccination. A Poisson regression model was used to estimate prevalence ratios and 95% confidence intervals. Results Data were collected from a total of 478 children. Only 112 (23.68%) were found to have visited a dentist; 67.77% of those had seen the dentist for preventive care. Most (63.11%) used public rather than private services. The use of dental services varied according to parental socioeconomic status; children from low socioeconomic backgrounds and those whose parents rated their oral health as “poor” used dental services less frequently. The reason for visiting the dentist also varied with socioeconomic status, in that children of parents with poor socioeconomic status and who reported their child’s oral health as “fair/poor” were less likely to have visited the dentist for preventive care. Conclusion This study demonstrated that psychosocial and socioeconomic factors are important predictors of the utilization of dental care services. PMID:24171711

The relationship between body system-based chronic conditions and dental utilization for Medicaid-enrolled children: a retrospective cohort study  

PubMed Central

Background Dental care is the most common unmet health care need for children with chronic conditions. However, anecdotal evidence suggests that not all children with chronic conditions encounter difficulties accessing dental care. The goals of this study are to evaluate dental care use for Medicaid-enrolled children with chronic conditions and to identify the subgroups of children with chronic conditions that are the least likely to use dental care services. Methods This study focused on children with chronic conditions ages 3-14 enrolled in the Iowa Medicaid Program in 2005 and 2006. The independent variables were whether a child had each of the following 10 body system-based chronic conditions (no/yes): hematologic; cardiovascular; craniofacial; diabetes; endocrine; digestive; ear/nose/throat; respiratory; catastrophic neurological; or musculoskeletal. The primary outcome measure was use of any dental care in 2006. Secondary outcomes, also measured in 2006, were use of diagnostic dental care, preventive dental care, routine restorative dental care, and complex restorative dental care. We used Poisson regression models to estimate the relative risk (RR) associated with each of the five outcome measures across the 10 chronic conditions. Results Across the 10 chronic condition subgroups, unadjusted dental utilization rates ranged from 44.3% (children with catastrophic neurological conditions) to 60.2% (children with musculoskeletal conditions). After adjusting for model covariates, children with catastrophic neurological conditions were significantly less likely to use most types of dental care (RR: 0.48 to 0.73). When there were differences, children with endocrine or craniofacial conditions were less likely to use dental care whereas children with hematologic or digestive conditions were more likely to use dental care. Children with respiratory, musculoskeletal, or ear/nose/throat conditions were more likely to use most types of dental care compared to other children with chronic conditions but without these specific conditions (RR: 1.03 to 1.13; 1.0 to 1.08; 1.02 to 1.12; respectively). There was no difference in use across all types of dental care for children with diabetes or cardiovascular conditions compared to other children with chronic conditions who did not have these particular conditions. Conclusions Dental utilization is not homogeneous across chronic condition subgroups. Nearly 42% of children in our study did not use any dental care in 2006. These findings support the development of multilevel clinical interventions that target subgroups of Medicaid-enrolled children with chronic conditions that are most likely to have problems accessing dental care.

A public aid clinic prototype: utilizing a dental hygiene educational facility to increase access to care.  

PubMed

Few dentists in a rural Midwestern community participate in providing oral health care to public aid recipients. In response, faculty at a baccalaureate degree dental hygiene program located at Southern illinois University, Carbondale (SIUC) proposed, developed, and implemented the Heartland Dental Clinic to serve Medicaid participants. The unique program utilizes existing facilities, staff, and students to provide comprehensive oral health care to underserved populations. The state awarded a small grant to cover start-up costs. Two dental units were upgraded with fiber optics to allow restorative procedures. Dental hygiene students provide intake examinations and preventive care, while a staff dentist provides restorative care, dentures, and examinations. Dental technology students and faculty fabricate prostheses. A part-time clinic manager facilitates communication, patient scheduling, and billing. Two local Rotary Club members volunteer as receptionists for the clinic on the one evening per week that the clinic operates. The Rotary Club purchased educational pamphlets, a television/VCR, videotapes, and two signs for the clinic. By locating the clinic in the existing SIUC facility and utilizing dental hygiene students, a staff dentist, volunteer receptionists and dentists, student workers, and health care management interns, the clinic overhead costs have been kept to a minimum. The clinic provides a unique opportunity for dental hygiene students to experience firsthand scheduling, billing, and treating public aid patients while providing patients with an additional source for oral health care. The Heartland Dental Clinic model represents a cost effective method for increasing oral health access to underserved populations while also benefiting students in an educational program.

Optical coherence tomography of dental structures  

NASA Astrophysics Data System (ADS)

In the past ten years Partial Coherence Interferometry (PCI) and Optical Coherence Tomography (OCT) have been successfully developed for high precision biometry and tomography of biological tissues. OCT employs the partial coherence properties of a superluminescent diode and the Doppler principle yielding resolution and precision figures of the order of a few microns. Presently, the main application fields of this technique are biometry and imaging of ocular structures in vivo, as well as its clinical use in dermatology and endoscopic applications. This well established length measuring and imaging technique has now been applied to dentistry. First in vitro OCT images of the cemento (dentine) enamel junction of extracted sound and decayed human teeth have been recorded. These images distinguish dentine and enamel structures that are important for assessing enamel thickness and diagnosing caries. Individual optical A-Scans show that the penetration depth into enamel is considerably larger than into dentine. First polarization sensitive OCT recordings show localized changes of the polarization state of the light backscattered by dental material. Two-dimensional maps of the magnitude of the interference intensity and of the total phase difference between two orthogonal polarization states as a function of depth can reveal important structural information.

Dental Anomalies and Dental Age Assessment in Treated Children with Acute Lymphoblastic Leukemia  

PubMed Central

Background This cross sectional study was performed to evaluate dental ages and incidence of dental anomalies in children treated for acute lymphoblastic leukemia (ALL). Methods and materials A total of 25 ALL patient who passed at least 2 years of chemotherapy and 25 healthy sex and age matched children were evaluated. Dental age as well as dental anomalies in shape, size, number, and structure was recorded based on their panoramic radiographies which were taken for dental purposes. Results The number of dental anomalies significantly increased in ALL treated children. Seven ALL cases (28%) in compression to only one (4%) in control group had at least one dental anomaly. However, there was neither statistically significant differences between the mean of dental (p=0.32) and chronologic age (p=0.12) in both groups, nor between dental age of cases and control group (p=0.62).The age at the onset of treatment as well as treatment durations has not affected dental age and the incidence of dental anomalies significantly (p<0.05). Conclusion Chemotherapy in children results in emergence of dental anomaly. Dental age, maturity, and development process however seems to be independent from chemotherapy. PMID:25598958

The use of dental services for children: Implications of the 2010 dental reform in Israel.  

PubMed

Routine dental examinations for children are important for early diagnosis and treatment of dental problems. The level of dental morbidity among Israeli children is higher than the global average. A July 2010 reform of Israel's National Health Insurance Law gradually offers free dental services for children up to age 12. The study examines the use of dental services for children and the factors affecting mothers' decision to take their children for routine checkups. In addition, the study examines the impact of the reform on dental checkups for children in various populations groups. A national representative sample comprising 618 mothers of children aged 5-18 was surveyed by telephone. The survey integrated the principles of the health beliefs model and socio-demographic characteristics. The results show that mothers' decision to take their children for dental checkups is affected by their socio-demographic status and by their health beliefs with respect to dental health. After the reform, the frequency of children's dental checkups significantly increased among vulnerable populations. Therefore, the reform has helped reduce gaps in Israeli society regarding children's dental health. Raising families' awareness of the reform and of the importance of dental health care together with expanding national distribution of approved dental clinics can increase the frequency of dental checkups among children in Israel.

Interactions between magnetic resonance imaging and dental material  

PubMed Central

Magnetic resonance imaging (MRI) has become a common and important life-saving diagnostic tool in recent times, for diseases of the head and neck region. Dentists should be aware of the interactions of various restorative dental materials and different technical factors put to use by an MRI scanning machine. Specific knowledge about these impacts, at the dentist level and at the level of the personnel at the MRI centers can save valuable time for the patient and prevent errors in MRI images. Artifacts from metal restorations are a major hindrance at such times, as they result in disappearance or distortion of the image and loss of important information. PMID:23946562

Survey of the Reasons for Dental Extraction in Eastern Nigeria  

PubMed Central

Background: Extraction of teeth is the commonest surgical procedure carried out in the dental surgery setting. Aim: The purpose of this survey was to identify the causes of teeth extraction in Eastern Nigeria. Subjects and Methods: Record forms for entering data and a self-addressed return envelope were distributed to 100 dental surgeons in Eastern Nigeria using a simple random selection. Results: Seventy-one (71; 71/100) dentists responded to the request and the total extractions carried out were 3998. There were 1508 (37.7%) extractions in males and 2490 (62.3%) in females with male-to-female extraction ratio of 1:1.7. In both male and female gender, there were more teeth extractions between the ages of 11 and 30 years. Extractions were recorded more in the lower social class (47.6%; 1903/3998). There were more extractions in the permanent (85.0%; 3398/3998) than deciduous (15.0%; 600/3998). The commonest reasons for teeth extraction were caries (55.2%; 2208/3998). Conclusion: The result of this study shows that dental caries is the commonest reason for tooth extraction in Eastern Nigeria. It is hoped that the study will facilitate the development of treatment and preventive procedures relevant to the problems observed in this part of Nigeria, thus minimizing the loss of teeth and its expected adverse consequences.

Some effects of disinfecting solutions on the properties of alginate impression material and dental stone.  

PubMed

The study investigated the effect of two disinfecting solutions on one brand of alginate impression material and dental stone. Control impressions were immersed in water for equivalent periods and the effect of storage of impressions after disinfection or control immersion in water was also investigated. There were no significant dimensional changes in impressions poured after one hour. All impressions stored for 16 hours before pouring showed significant dimensional changes. Mixing dental stone with one disinfectant caused a significant softening of the cast. It is strongly recommended that all impressions are thoroughly rinsed with water after disinfection to prevent incorporation of disinfectant in the cast. PMID:12192949

[Dental care, dental diseases and dentistry in antiquity].  

PubMed

Numerous written relicts, belletristic works (poems of Martial, Juvenal, Ovid etc.) indicate that oral hygiene and its tools (toothbrush, toothpick, use of tooth pastes and tooth-powder) were used long before our times. Already ancient people started to remove, file, dye and inlay teeth. The teeth were dyed red, green or black in Egypt, red or brown (with henna or betel) in India, white by Romans. The teeth decoration has a long but forgotten history. The most skillful and artistic work was done by the Maya's between 900 BC and 1500 AD. The modification of contours (more than fifty forms) of the incisors were practiced also in Mesoamerica. Dentistry was surely practiced in ancient Egypt, India, China, Greece and Rome, while odontology and especially suitable dental appliances arose only by Etruscan. Dental prosthesis, including bridges and simple retention bands were invented by the Etruscans 2500 years ago. These Etruscan bridges were worn mostly by females, suggesting that cosmetics was the principal dental concern. Some,--if not all--of the Roman and other prostheses have been purely ornamental. Orthodontic appliances are also Etruscan invention. The holes caused by caries were filled with garlic, incense, caraway seed in Egypt, with wood or lead in Rome, and with "silver-paste" (amalgam) in ancient China. The toothache was cured with poppy-tee, or hashish and nightshade plants (Solanaceae) in Egypt, Greece, Roman Empire while with coca (Erythroxylon coca) in South-America. PMID:20481107

Effects of enamel matrix genes on dental caries are moderated by fluoride exposures.  

PubMed

Dental caries (tooth decay) is the most common chronic disease, worldwide, affecting most children and adults. Though dental caries is highly heritable, few caries-related genes have been discovered. We investigated whether 18 genetic variants in the group of non-amelogenin enamel matrix genes (AMBN, ENAM, TUFT1, and TFIP11) were associated with dental caries experience in 13 age- and race-stratified samples from six parent studies (N = 3,600). Linear regression was used to model genetic associations and test gene-by-fluoride interaction effects for two sources of fluoride: daily tooth brushing and home water fluoride concentration. Meta-analysis was used to combine results across five child and eight adult samples. We observed the statistically significant association of rs2337359 upstream of TUFT1 with dental caries experience via meta-analysis across adult samples (p < 0.002) and the suggestive association for multiple variants in TFIP11 across child samples (p < 0.05). Moreover, we discovered two genetic variants (rs2337359 upstream of TUFT1 and missense rs7439186 in AMBN) involved in gene-by-fluoride interactions. For each interaction, participants with the risk allele/genotype exhibited greater dental caries experience only if they were not exposed to the source of fluoride. Altogether, these results confirm that variation in enamel matrix genes contributes to individual differences in dental caries liability, and demonstrate that the effects of these genes may be moderated by protective fluoride exposures. In short, genes may exert greater influence on dental caries in unprotected environments, or equivalently, the protective effects of fluoride may obviate the effects of genetic risk alleles.

NATURAL HISTORY OF DENTAL PLAQUE ACCUMULATION IN MECHANICALLY VENTILATED ADULTS: A DESCRIPTIVE CORRELATIONAL STUDY  

PubMed Central

Summary Objective The purpose of this study was to describe the pattern of dental plaque accumulation in mechanically ventilated adults. Accumulation of dental plaque and bacterial colonization of the oropharynx is associated with a number of systemic diseases including ventilator associated pneumonia. Research Methodology/Design Data were collected from mechanically ventilated critically ill adults (n=137), enrolled within 24 hours of intubation. Dental plaque, counts of decayed, missing and filled teeth and systemic antibiotic use was assessed on study days 1, 3, 5 and 7. Dental plaque averages per study day, tooth type and tooth location were analyzed. Setting Medical Respiratory, Surgical Trauma and Neuroscience ICU’s of a large tertiary care center in the southeast United States. Results Plaque: All surfaces > 60% plaque coverage from day 1 to day 7; Molars and Premolars contained greatest plaque average >70%. Systemic antibiotic use on day 1 had no significant effect on plaque accumulation on day 3 (p=0.73). Conclusions Patients arrive in critical care units with preexisting oral hygiene issues. Dental plaque tends to accumulate in the posterior teeth (molars and premolars) that may be hard for nurses to visualize and reach; this problem may be exacerbated by endotracheal tubes and other equipment. Knowing accumulation trends of plaque will guide the development of effective oral care protocols. PMID:22014582

Near-IR polarization imaging of sound and carious dental enamel  

NASA Astrophysics Data System (ADS)

A thorough understanding of how polarized near-IR light propagates through sound and carious dental hard tissues is important for the development of dental optical imaging systems. New optical imaging tools for the detection and assessment of dental caries (dental decay) such as near-IR imaging and optical coherence tomography can exploit the enhanced contrast provided by polarization sensitivity. In this investigation, an automated system was developed to collect images for the full 16-element Mueller Matrix. The polarized light was controlled by linear polarizers and liquid crystal retarders and the 36 images were acquired as the polarized near-IR light propagates through the enamel of extracted human thin tooth sections. In previous work, we reported that polarized light is rapidly depolarized by demineralized enamel, and sound and demineralized dentin.1 The rapid depolarization of polarized light by dental caries in the near-IR provides high contrast for caries imaging and detection. In this initial study, major differences in the Mueller matrix elements were observed in both sound and demineralized enamel which supports this approach and warrants further investigation.

Oral infections may play a role in Alzheimer's disease (AD). Objective To describe the orofacial pain, dental characteristics and associated factors in patients with Alzheimer's Disease that underwent dental treatment. Method 29 patients with mild AD diagnosed by a neurologist were included. They fulfilled the Mini Mental State Exam and Pfeffer's questionnaire. A dentist performed a complete evaluation: clinical questionnaire; research diagnostic criteria for temporomandibular disorders; McGill pain questionnaire; oral health impact profile; decayed, missing and filled teeth index; and complete periodontal investigation. The protocol was applied before and after the dental treatment. Periodontal treatments (scaling), extractions and topic nystatin were the most frequent. Results There was a reduction in pain frequency (p=0.014), mandibular functional limitations (p=0.011) and periodontal indexes (p<0.05), and an improvement in quality of life (p=0.009) and functional impairment due to cognitive compromise (p<0.001) after the dental treatment. Orofacial complaints and intensity of pain also diminished. Conclusion The dental treatment contributed to reduce co-morbidities associated with AD and should be routinely included in the assessment of these patients. PMID:25517641

Evaluation of Senior Dental Students' General Attitude towards the Use of Rubber Dam: A Survey among Two Dental Schools  

PubMed Central

The purpose of this study was to evaluate the general attitude of senior dental students towards rubber dam use, specifically focusing on endodontic practices prior to starting to serve community. Questionnaires were distributed to senior year students of a private school and a state school in Istanbul. Questions were asked about areas where the students used rubber dam, its advantages and difficulties, and whether they agreed or disagreed with some aspects of the rubber dam. The private school students rated isolation whereas those of the state school selected prevention of aspiration which the top advantage rubber dam provides. Students of the state school agreed with the opinion that isolation cannot be achieved without rubber dam and it extended the procedure with a significantly higher ratio compared to the private school. Within the limitations of the present study, it can be concluded that the perceptions of dental students on rubber dam needs to be improved and strategies should be developed so that this valuable adjunct will comprise one of the indispensable elements of dental care.

Taste Genes Associatedwith Dental Caries  

PubMed Central

Dental caries is influenced by a complex interplay of genetic and environmental factors, including dietary habits. Previous reports have characterized the influence of genetic variation on taste preferences and dietary habits. We therefore hypothesized that genetic variation in taste pathway genes (TAS2R38, TAS1R2, GNAT3) may be associated with dental caries risk and/or protection. Families were recruited by the Center for Oral Health Research in Appalachia (COHRA) for collection of biological samples, demographic data, and clinical assessment of oral health, including caries scores. Multiple single-nucleotide polymorphism (SNP) assays for each gene were performed and analyzed by transmission disequilibrium test (TDT) analysis (FBAT software) for three dentition groups: primary, mixed, and permanent. Statistically significant associations were seen in TAS2R38 and TAS1R2 for caries risk and/or protection. PMID:20858777

New developments in dental adhesion.  

PubMed

Numerous simplified adhesives have been introduced to the dental market within the last few years, sometimes without comprehensive testing to validate the performance claimed by the respective manufacturers. Mild self-etch adhesives are unable to etch enamel to provide adequate retention for bonded restorations. Although high early resin-dentin bond strength values can be achieved with some self-etch adhesives, their resistance to thermal and mechanical stresses over time is disappointing. In light of the current drawbacks attributed to all-in-one self-etch adhesives, etch-and-rinse adhesives are still the benchmark for dental adhesion in routine clinical use. This article summarizes current issues and factors related to the performance of adhesives. PMID:17532916

Soft skills and hard skills are essential in the practice of dentistry. While hard skills deal with technical proficiency, soft skills relate to a personal values and interpersonal skills that determine a person's ability to fit in a particular situation. These skills contribute to the success of organisations that deal face-to-face with clients. Effective soft skills benefit the dental practice. However, the teaching of soft skills remains a challenge to dental schools. This paper discusses the different soft skills, how they are taught and assessed and the issues that need to be addressed in their teaching and assessment.

Dental infection simulating skin lesion.  

PubMed

Orocutaneous fistulas or cutaneous sinus, a tract of dental origin, is an uncommon but well-documented condition that usually requires emergency treatment. Such condition may be misdiagnosed by physicians and dentists and may sometimes be confused with bone and skin tumor, osteomyelitis, congenital fistula, salivary gland fistula, pyogenic granuloma, infected cyst, deep mycotic infection, and other pathologies. A case of facial sinus tract that was initially misdiagnosed by a physician as a nonodontogenic lesion is presented. Nonsurgical endodontic therapy was the treatment of choice for this case. Facial cutaneous sinus tracts must be considered of dental origin. Early diagnosis and prompt treatment minimize patient discomfort and esthetic problems, reducing the possibility of further complications such as sepsis and osteomyelitis. PMID:22892779

Dental Photothermal Radiometry: Theoretical Analysis.  

NASA Astrophysics Data System (ADS)

Dental enamel demineralization in its early stages is very difficult to detect with conventional x-rays or visual examination. High-resolution techniques, such as scanning electron microscopy, usually require destruction of the tooth. Photothermal Radiomety (PTR) was recently applied as a safe, non-destructive, and highly sensitive tool for the detection of early dental demineralization, artificially created on the enamel surface. The experiments showed very high sensitivity of the measured signal to incipient changes in the surface structure, emphasizing the clinical capabilities of the method. In order to analyze the biothermophotonic phenomena in a tooth sample during the photothermal excitation, a theoretical model featuring coupled diffuse-photon-density-wave and thermal-wave fields was developed. Numerical simulations identified the effects on the PTR signal of changes in optical and thermal properties of enamel and dentin as a result of demineralization. The model predictions and experimental results will be compared and discussed.

Analysis of 415 adverse events in dental practice in Spain from 2000 to 2010  

PubMed Central

Introduction: The effort to increase patient safety has become one of the main focal points of all health care professions, despite the fact that, in the field of dentistry, initiatives have come late and been less ambitious. The main objective of patient safety is to avoid preventable adverse events to the greatest extent possible and to limit the negative consequences of those which are unpreventable. Therefore, it is essential to ascertain what adverse events occur in each dental care activity in order to study them in-depth and propose measures for prevention. Objectives: To ascertain the characteristics of the adverse events which originate from dental care, to classify them in accordance with type and origin, to determine their causes and consequences, and to detect the factors which facilitated their occurrence. Material and Methods: This study includes the general data from the series of adverse dental vents of the Spanish Observatory for Dental Patient Safety (OESPO) after the study and analysis of 4,149 legal claims (both in and out of court) based on dental malpractice from the years of 2000 to 2010 in Spain. Results: Implant treatments, endodontics and oral surgery display the highest frequencies of adverse events in this series (25.5%, 20.7% and 20.4% respectively). Likewise, according to the results, up to 44.3% of the adverse events which took place were due to predictable and preventable errors and complications. Conclusions: A very significant percentage were due to foreseeable and preventable errors and complications that should not have occurred. Key words:Patient safety, adverse event, medical care risk, dentistry. PMID:24880444

Bone growth around dental implants.  

PubMed

For the complete understanding of stimulation of bone growth around dental implants, a thorough knowledge is necessary regarding the reaction of bone to trauma and to a variety of implant materials. The atraumatic preparation of the bony implant bed serves to create the most favorable situation for the formation of bone around any implant material. Some implant materials are more likely to result in soft tissue encapsulation despite the most careful handling of bone; others result in different amounts of implant-bone contact zones. From the character and the amount of bone formation around different implants, it can be concluded whether the used materials are biocompatible. Titanium-surfaced implants may not demonstrate the biocompatibility that is seen with hydroxyapatite-coated implants. However, the results seen with hydroxyapatite-coated implants have to be viewed critically because the biointegrity of these coatings has not been demonstrated until now. On the other hand, titanium-surfaced implants have success rates for as long as 25 years and enable the implantologist to rely on a well-accepted implant material. The use of guided tissue regeneration and the sinus augmentation technique appear to enable the implantologist to stimulate bone formation around dental implants. These techniques may extend the limits for the successful placement of dental implants into bone-deficient sites. PMID:1879579

Percutaneous exposure incidents remain a main concern, as exposure to serious infectious agents is a virtual risk. Minimizing percutaneous exposure incidents and their consequences should continue to be considered, including sound infection control practices, continuing education, and hepatitis B vaccination. Basically, for any infection control strategies, dentists should be aware of individual protective measures and appropriate sterilization or other high-level disinfection utilities. Strained posture at work disturbs the musculoskeletal alignment and leads to stooped spine. The stooped posture also involved certain groups of muscles and joints. This may lead to diseases of the musculoskeletal system. Continuous educating and appropriate intervention studies are needed to reduce the complication of these hazards. So, it is important for dentists to remain constantly up-to-date about measures on how to deal with newer strategies and dental materials, and implicates the need for special medical care for this professional group.

[Thermal diffusivity of dental cements].  

PubMed

Thermal insulative efficiency, is one of the desirable properties of the dental cements. In this study, the thermal diffusivity of three types of dental cements, were measured. Thermal diffusivity was determined by the following method. Two thermo-couples were used and connected to a chart record, the first was embedded in the cylindrical block of the cement specimen and the other in a mixing of ice and water (reference thermocouple). All them were set in a apparatus consisting of a double cooling bath. Calculation of thermal diffusivity were based on the curve provided of the record during cooling of the cement and a theoretical mathematic model. Values were ranged from 2,985 to 3,934 cm2.sec-1. ZOE cement exhibited the highest value, the glass-ionomers the lowest and the poly-carboxylates were average. The results showed that the thermal diffusivity of the cements is dependent from the type of the cement but the differences between them were not statistically significant. Additionally, the values obtained were about the same as the dentin, so the dental cements may consider as good thermal insulators. PMID:2130338

Nanostructured Surfaces of Dental Implants  

PubMed Central

The structural and functional fusion of the surface of the dental implant with the surrounding bone (osseointegration) is crucial for the short and long term outcome of the device. In recent years, the enhancement of bone formation at the bone-implant interface has been achieved through the modulation of osteoblasts adhesion and spreading, induced by structural modifications of the implant surface, particularly at the nanoscale level. In this context, traditional chemical and physical processes find new applications to achieve the best dental implant technology. This review provides an overview of the most common manufacture techniques and the related cells-surface interactions and modulation. A Medline and a hand search were conducted to identify studies concerning nanostructuration of implant surface and their related biological interaction. In this paper, we stressed the importance of the modifications on dental implant surfaces at the nanometric level. Nowadays, there is still little evidence of the long-term benefits of nanofeatures, as the promising results achieved in vitro and in animals have still to be confirmed in humans. However, the increasing interest in nanotechnology is undoubted and more research is going to be published in the coming years. PMID:23344062

Functional expression of dental plaque microbiota.  

PubMed

Dental caries remains a significant public health problem and is considered pandemic worldwide. The prediction of dental caries based on profiling of microbial species involved in disease and equally important, the identification of species conferring dental health has proven more difficult than anticipated due to high interpersonal and geographical variability of dental plaque microbiota. We have used RNA-Seq to perform global gene expression analysis of dental plaque microbiota derived from 19 twin pairs that were either concordant (caries-active or caries-free) or discordant for dental caries. The transcription profiling allowed us to define a functional core microbiota consisting of nearly 60 species. Similarities in gene expression patterns allowed a preliminary assessment of the relative contribution of human genetics, environmental factors and caries phenotype on the microbiota's transcriptome. Correlation analysis of transcription allowed the identification of numerous functional networks, suggesting that inter-personal environmental variables may co-select for groups of genera and species. Analysis of functional role categories allowed the identification of dominant functions expressed by dental plaque biofilm communities, that highlight the biochemical priorities of dental plaque microbes to metabolize diverse sugars and cope with the acid and oxidative stress resulting from sugar fermentation. The wealth of data generated by deep sequencing of expressed transcripts enables a greatly expanded perspective concerning the functional expression of dental plaque microbiota. PMID:25177549

Silicosis in dental laboratory technicians--five states, 1994-2000.  

PubMed

Silicosis is a debilitating, sometimes fatal, yet preventable occupational lung disease caused by inhaling respirable crystalline silica dust. Although crystalline silica exposure and silicosis have been associated historically with work in mining, quarrying, sandblasting, masonry, founding, and ceramics, certain materials and processes used in dental laboratories also place technicians at risk for silicosis. During 1994--2000, occupational disease surveillance programs in five states identified nine confirmed cases of silicosis among persons who worked in dental laboratories; four persons resided in Michigan, two in New Jersey, and one each in Massachusetts, New York, and Ohio. This report describes three of the cases and underscores the need for employers of dental laboratory technicians to ensure appropriate control of worker exposure to crystalline silica. PMID:15017375

Oral and Dental Findings of Dyskeratosis Congenita  

PubMed Central

Dyskeratosis congenital (DC) is a rare condition characterized by reticulate skin hyperpigmentation, mucosal leukoplakia, and nail dystrophy. More serious features are bone marrow involvement with pancytopenia and a predisposition to malignancy. The purpose of this case report is to describe the oral and dental findings in children with DC syndrome. A 10-year-old male diagnosed with DC was admitted because of extensive caries and toothache. Inadequate oral hygiene and extensive caries were observed in oral examination of the patient. Plaque accumulation was seen in gingival border of maxillary teeth. Papillary atrophy on the tongue was observed. Short and blunted roots of mandible incisors and upper and lower molars were determined on the radiographic examination. Dryness on the lips and commisuras, ectropion on his eyes, and epiphora were observed. Hematologic tests were performed and showed aplastic anemia at the age of 2. At the age of 4, the bone marrow transplantation was performed. Dermatological findings occurred after the bone marrow transplantation. The skin of the patient was thin, dry, and wrinkled in some areas. He had palmoplantar hyperkeratosis and syndactylia on his fingers. Endodontic treatment procedures were applied and other extensive caries are still being restored. The patient will be given full preventive care during regular follow-up. Oral hygiene was improved to the optimum level. PMID:25610666

Brazilian primary school teachers' knowledge about immediate management of dental trauma  

PubMed Central

OBJECTIVE: To assess the level of knowledge of primary school teachers in the public school network of Northeastern Brazil with respect to management of dental trauma and its relationship with prognosis. METHODS: A questionnaire was applied to 195 school teachers of public schools in Northeastern Brazil. The questionnaire comprised 12 objective questions about dental trauma and methods for its prevention and management. Data were submitted to chi-square test and Poisson regression test (P > 0.05). RESULTS: Out of the 141 teachers who responded the questionnaires, the majority were women (70.2%) and most of them had experienced previous dental accidents involving a child (53.2%). The majority (84.4%) had incomplete college education and few were given some training on how to deal with emergency situations during their undergraduate course (13.5%) or after it (38.3%). Their level of knowledge about dental trauma and emergency protocols showed that unsatisfactory knowledge level was associated with the male sex: 46% higher for men in comparison to women (P = 0.025). CONCLUSIONS: Approximately half of teachers evaluated had unsatisfactory knowledge about dental trauma and emergency protocols, with female teachers showing more knowledge than men.

Cutaneous sinus tracts of dental origin: clinical review of 37 cases.  

PubMed

Cutaneous sinus tracts in the face and neck region are often dental in origin. The purpose of this study was to characterize the clinical features and treatment of 37 consecutive cases of odontogenic cutaneous sinus tracts, collected and reviewed in a 15-year period. More than half of the patients (21 cases, 57%) were referred from medical doctors, particularly plastic surgeons and dermatologists. The sinus tracts were associated with caries (26 cases), incomplete endodontic treatment (7), crown fracture (2), vertical root fracture (1) and impacted mandibular third molar (1). They occurred most often in adolescents and adults (30 cases, 81%). The most common causative teeth were mandibular teeth (34 teeth, 85%). The chin, submental, and cheek areas were the most common sites of sinus tracts (30 cases, 81%). The majority of causative teeth (32 teeth, 80%) were treated endodontically. All fistulas healed uneventfully after proper dental treatment, without cosmetic surgery. In 63% (20 cases) of the recorded cases, complete resolution occurred within 8 weeks. Half of the patients had had fistulas for more than 6 months before receiving dental treatment, demonstrating that delays in proper diagnosis and treatment were common. As most patients suffered from unnecessary medication or surgery due to the delay of dental treatment, early dental consultation and treatment is important. Conventional endodontic treatment should be the treatment of choice if the tooth is salvageable. The increasing incidence of incomplete endodontic treatment in association with the occurrence of sinus tracts indicates that standardized endodontic therapy should be emphasized for prevention.

[Characteristics of the access and utilization of public dental services in medium-sized cities].  

PubMed

This cross-sectional study sought to describe the main characteristics of access and utilization of primary and specialized public dental services in two medium-sized cities in Bahia with 100% coverage of the Family Health Program. A survey of 952 households and 2.539 individuals aged over 15 years was conducted. The main variables analyzed were: perceived oral health needs, demand for the service, barriers of organizational access and the type of service and procedure utilized. The use of specialized public dental services was of 11.7% and primary care was 26%. In the city where there was greater use of public dental services, there was less use of private services. The main barrier to access remained in primary care (from 5.0% to 15.2%). There was little interface between secondary care a primary care, as only 16.6% of users returned to this level of care. In conclusion, the main barrier to access in cities with specific organizational and geographic realities appears to be in primary dental care. Individual preventive actions were little reported. It is recommended that barriers to access in primary care be eliminated, and also that a protocol (clinical guides) be established to foster the continuity and longitudinality of primary dental care.

Ensuring the global availability of high-quality dental restorative materials.  

PubMed

The Minamata Convention, a global legally binding instrument (treaty) on mercury, has been the catalyst for the emerging agenda on global dental materials research. If the current and future challenges of oral health maintenance and healing on a global scale are to be met, a logical and effective research agenda for the discovery and introduction of new, environmentally sustainable, dental materials must be developed through a coordinated effort involving materials scientists, dental clinicians, representatives of industry, members of regional and national regulatory bodies, and advocacy from research organizations. For universal impact, this agenda should be created with awareness of several important ongoing initiatives, such as the WHO non-communicable diseases action plan, the UN sustainable development agenda, and the IADR Global Oral Health In Inequalities Research Agenda (GOHIRA). A significant contributor to this cause is the FDI and its membership, who, through their Vision 2020 initiative, acknowledge their role and responsibility in globally preventing and managing dental disease and providing leadership to the profession in terms of information dissemination and affecting change. Dental researchers also have an obligation to advocate for appropriate funding to match the identified research needs, thus enhancing the possibility that key decision-makers will provide the needed support to achieve the research agenda agreed upon by this diverse group of stakeholders.

Dental squash injuries - a survey among players and coaches in Switzerland, Germany and France.  

PubMed

Squash belongs to sporting activities with medium risk of causing dental trauma. Because of high velocity, close body contact and the use of rackets the injury potential in squash has increased. The aim of this work was to conduct a comparative study between Switzerland, Germany and France on a number of issues: the frequency of dental and facial injuries in squash, athletes' habits of wearing mouthguards, as well as the general level of information about emergency measures after a dental trauma and the resulting consequences. Using a standardized questionnaire a total of 653 individuals, 600 squash players and their 53 coaches, were interviewed. In each of the three countries 200 players belonging to four different divisions (juniors, amateurs, semi-professionals and professionals) were surveyed. Of these 653 interviewees 133 (20.4%) have already observed a dental injury; 27 (4.5%) have experienced a dental trauma themselves. Less than half of all interviewed players and coaches (47.6%) were aware of the possibility of replanting avulsed teeth. Just 5.1% were familiar with the tooth rescue kit. Only one individual wore a mouthguard. The results show that the area of squash requires more information about prevention through sports associations, coaches and dentists. PMID:16942551

Dental caries and erosion status of 12-year-old Hong Kong children  

PubMed Central

Background This study aimed to assess the dental caries and erosion status of 12-year-old Hong Kong children and study the determinants of dental caries and dental erosion of these children. Methods The survey was performed from 2011 to 2012 with ethics approval. Stratified random sampling was adopted to select 12-year-old children in 7 primary schools in Hong Kong. The participating parents were asked to complete a self-administered questionnaire concerning their children’s diet and oral health habits. The children were examined for caries status with WHO criteria by 3 calibrated examiners. Detection of dental erosion followed Basic Erosive Wear Examination (BEWE) criteria. Results A total of 704 children were recruited and 600 (316 boys, 53%) participated in the survey. There were 124 children (21%) with caries experience (DMFT?>?0) and their DMFT was 0.34?±?0.76. About half of their decay was unfilled (DT?=?0.16?±?0.52) The DMFT of girls and boys were 0.45?±?0.89 and 0.23?±?0.61, respectively (p?=?0.001). Girls also had a higher DT (0.21?±?0.62 compared with 0.11?±?0.41, p?=?0.013) and FT than boys (0.23?±?0.63 compared with 0.12?±?0.44, p?=?0.016). Most children (75%) had at least some sign of erosion (BEWE?>?0), but no severe erosion (BEWE?=?3). Logistic regression showed girls who consumed soft drinks and took vitamin C supplements had higher caries risk. Dental erosion was more severe among the children who had caries experience and consumed fruit juice. Conclusions The 12-year-old Hong Kong children had low caries experience, and almost half of the decay was left untreated. Although severe erosion was not found, many children had early signs of erosion. PMID:24397565

Does the presence of the Helicobacter pylori in the dental plaque associate with its gastric infection? A meta-analysis and systematic review  

PubMed Central

Background: There is a great deal of studies on the relationship between the existence of Helicobacter pylori (H. pylori) in oral cavity (dental plaque) and in stomach of patients, with conflicting results worldwide. The purpose of this study was to systematically review the existing litreature to assess if the dental plaque could be a source of gastric H. pylori infection and to explore the source of heterogeneity around it. Methods: We searched all the papers published since 2000 on international (Medline, ISI, Embase) databases using standard keywords. Two researchers evaluated the articles with standard critical appraisal form independently and those articles with the quality acquired greater than 70% were included in the study. The combined results were calculated with weighted average and the source of hetrogeneity was tested by meta-regression (random) model. Results: Finally, 23 studies were included (1861 patients). The prevalence of co-infection of gastric and dental plaque H. pylori was 49.7% (95% CI 16–83.4%) and the percent of agreement between the dental plaque H. pylori status and the gastric H. pylori was estimated as 82%. Only one study has reported that dental treatment has a preventive effect on the recurrence of gastric H. pylori infection. Conclusion: Co-infection of gastric H. pylori and dental plaque is reported by half of the studies. However, there is not enough evidence for the efficacy of dental treatment on prevention of recurrent gastric H. pylori infection. PMID:22135688

Cortical representation area of human dental pulp.  

PubMed

To elucidate the dental pulp-representing area in the human primary somatosensory cortex and the presence of A-beta fibers in dental pulp, we recorded somatosensory-evoked magnetic fields from the cortex in seven healthy persons using magnetoencephalography. Following non-painful electrical stimulation of the right maxillary first premolar dental pulp, short latency (27 ms) cortical responses on the magnetic waveforms were observed. However, no response was seen when stimulation was applied to pulpless teeth, such as devitalized teeth. The current source generating the early component of the magnetic fields was located anterior-inferiorly compared with the locations for the hand area in the primary somatosensory cortex. These results demonstrate the dental pulp representation area in the primary somatosensory cortex, and that it receives input from intradental A-beta neurons, providing a detailed organizational map of the orofacial area, by adding dental pulp to the classic "sensory homunculus".

Results: PI was significantly higher among patients with exaggerated gag reflex (1.91 ± 0.95) and dental anxiety patients (1.82 ± 0.89) compared to the control group (1.27 ± 0.74; P < 0.001). DMFT was significantly higher among patients with dental anxiety (13.64 ± 7.57) compared to patients with exaggerated gag reflex (10.52 ± 5.42; P = 0.033), and between both groups compared to the control group (4.09 ± 4.034; P < 0.001). Multivariate logistic regression analysis revealed that PI, DMFT and age were positively associated with exaggerated gag reflex and that DMFT and educational level were positively associated with dental anxiety compared to the control group. DMFT was the only significant parameter positively associated with dental anxiety compared to exaggerated gag reflex. Conclusion: DMFT and PI scores were higher among patients with dental anxiety and exaggerated gag reflex. Clinicians should consider additional oral hygiene measures and education, maintenance meetings and recall visits in those patients, as well as using supplementary aids, such as fluoride mouthwash and fluoride varnish applications, to maintain oral hygiene without triggering the exaggerated gag reflex.

Sinus tracts presenting on the face may be the result of dental pathosis. This etiologic possibility should be ruled out before such lesions are treated by prolonged antibiotic therapy or surgical excision. The diagnosis can often be confirmed by a good clinical intraoral examination supplemented by appropriate radiographs. Four cases are presented in which treatment of the underlying pathology resulted in resolution of the sinus tract. ImagesFig. 1Fig. 2Fig. 3Fig. 4Fig. 5Fig. 6Fig. 7Fig. 8Fig. 9 PMID:21286180

[Professional behaviour in dental education].  

PubMed

The professional behaviour of future dentists is an important topic in dental curricula. Aspects of professional behaviour are, among other things: being respectful to patients, putting the interest of the patients first, reliability, integrity, and knowing one's professional limitations and acting according to them when treating patients. Throughout the curriculum students receive feedback on their functioning with regard to professional behaviour and are also examined on those points. At the programme at the Academic Centre for Dentistry Amsterdam, experience has been gained in recent years in addressing and evaluating (un)professional behaviour among students. PMID:22812272

Effect of health promotion and fluoride varnish on dental caries among Australian Aboriginal children: results from a community-randomized controlled trial*  

PubMed Central

Objectives We tested a dental health program in remote Aboriginal communities of Australia's Northern Territory, hypothesizing that it would reduce dental caries in preschool children. Methods In this 2-year, prospective, cluster-randomized, concurrent controlled, open trial of the dental health program compared to no such program, 30 communities were allocated at random to intervention and control groups. All residents aged 18–47 months were invited to participate. Twice per year for 2 years in the 15 intervention communities, fluoride varnish was applied to children's teeth, water consumption and daily tooth cleaning with toothpaste were advocated, dental health was promoted in community settings, and primary health care workers were trained in preventive dental care. Data from dental examinations at baseline and after 2 years were used to compute net dental caries increment per child (d3mfs). A multi-level statistical model compared d3mfs between intervention and control groups with adjustment for the clustered randomization design; four other models used additional variables for adjustment. Results At baseline, 666 children were examined; 543 of them (82%) were re-examined 2 years later. The adjusted d3mfs increment was significantly lower in the intervention group compared to the control group by an average of 3.0 surfaces per child (95% CI = 1.2, 4.9), a prevented fraction of 31%. Adjustment for additional variables yielded caries reductions ranging from 2.3 to 3.5 surfaces per child and prevented fractions of 24–36%. Conclusions These results corroborate findings from other studies where fluoride varnish was efficacious in preventing dental caries in young children. PMID:20707872

Diversity and critical forces in dental education.  

PubMed

Critical issues that affect dental education and the connection between science and practice include the community, managed patient care, public skepticism and fiscal support, and shifting demography in patterns of oral disease as well as the background of students entering the dental profession. During the past several decades, there have been major shifts in the patterns of oral disease, most recently described in results of the NHANES III dental survey. The diversity and background of students entering the dental profession have changed dramatically as well, and present estimates of change in U.S. population are no less volatile. Funding for dental education in constant dollars is decreasing nationally, with declining support from state and federal sources and a much greater reliance on clinical and development income. Recent recommendations by the Institute of Medicine and Pew Health Commission and reactions to those recommendations by representative dental organizations-particularly the American Dental Association, American Association of Dental Schools, and the American Association of Dental Examiners-have significant implications for the structure of dental education. All of these factors are tempered by the emergence of managed patient care and the implications of that environment to increasing the level of academic excellence of students, improving the quality of care delivered to patients, and enhancing the scholarly contributions of faculty. These forces may represent an opportunity to maintain a well-documented national excellence in oral health care, expand the educational options to meet student demand and interest, increase the biological and behavioral background of our graduates, and explore new educational approaches to preclinical and clinical training.

Greater inequalities in dental treatment than in disease experience.  

PubMed

This study aimed to (1) describe social gradients in dental caries in a population-level survey and (2) examine whether inequalities are greater in disease experience or in its treatment. Using data from Australia's National Survey of Adult Oral Health 2004-2006, we examined absolute and relative income inequalities for DMFT and its separate components (DT, MT, FT) using adjusted proportions, means, and health disparity indices [Slope Index of Inequality (SII) and Relative Index of Inequality (RII)]. Approximately 90% of Australian adults had experienced caries, with prevalence ranging from 89.7% in the highest to 96.6% in the lowest income group. Social gradients in caries were evident across all components of DMFT, but particularly notable in Missing (SII = -15.5, RII = -0.3) and untreated Decay (SII = -23.7, RII = -0.9). Analysis of age- and gender-adjusted data indicated less variation in levels of disease experienced (DMFT) than in the health outcomes of its management (missing teeth). The findings indicate that social gradients for dental caries have a greater effect on how the disease was treated than on lifetime disease experience. PMID:25081039

Misfit profile of dental bridges.  

PubMed

Clinical evidence has shown that dental bridge (DB) misfit is more frequent than individual crown restoration misfit, and that it causes restorative failures. A comparative study of misfit profiles was performed for the most common clinical situations in mouth rehabilitation procedures with fixed restorations: gold-cast DB and porcelain metal alloy DB. Evidence from this study may lead dentists to consider the advantages and weaknesses of one structure type over the other. The results obtained showed two different profiles, with the porcelain metal alloy (PMA) DB being less predictable than the gold-cast DB. The posterior abutment restoration tends to come apart distally from the tooth structure and get closer to the mesial aspect, while keeping distal-medial separation with respect to the anterior abutment. The gold-cast DBs showed a separation pattern in which the distal end comes away from the molar and the medial end from the premolar, getting clearly closer to the faces next to the pontic: its distal aspect gets closer to the premolar and mesially to the molar The study has also shown that even though the adaptive patterns are different, is less in PMA than in gold alloys, the latter being used only in a small percentage of clinical indications in oral rehabilitation, mainly due to aesthetic demands and high costs. The impact of this research in clinical dentistry is that PMA DBs have shown worst marginal adaptation areas where clinically, there is lack of vision or inaccessibility for appropriate dental preparation.

Impact of community-based oral health experiences on dental students' attitudes towards caring for the underserved.  

PubMed

Dental students' attitudes towards access to dental care for the underserved may be impacted by participation in community oral health promotion programs that target individuals in underserved communities. At the University of Southern California School of Dentistry, freshman dental students provide classroom oral health promotion and preventive dental care programs to underserved elementary school children. One hundred forty-four freshman dental students were surveyed three times during their freshman year-before, during, and after participation in these programs. The students' attitudes about societal expectations, health professionals' responsibility, access to care, and students' personal efficacy to positively impact the need for expanded oral health care services for segments of the population were measured. Students reported positive attitudes in all categories throughout the study period. The students' attitudes about societal expectations to care for the oral health of the underserved remained stable over the study period, but they became more uncertain of who should be responsible for fulfilling that obligation, who should receive that care, and their capability to provide this care while in dental school. These changes in attitude may reflect the students' greater understanding of the complexity of the determinants of oral health as a consequence of their community education experiences.

The Prevalence of Dental Caries in Primary Dentition in 4- to 5-Year-Old Preschool Children in Northern Palestine  

PubMed Central

Aim. To determine the prevalence of dental caries among a representative sample of preschool children (4-5 years old) who were accompanied by their parents to the dental centre of the Arab American University in Jenin whether they come seeking dental treatment or as visitors with adult patients. Materials and Methods. 1376 children of both sexes were investigated by three calibrated and trained examiners for dental caries using the dmft index according to the WHO method. Results. 76% of the studied children have already experienced dental caries at the age of 4-5 years (1046 children). The mean dmft score was found to be 2.46 while the other 24% of children were caries-free. There was no significant difference in caries prevalence between boys and girls (77.2% versus 74.6%). Children of highly educated and college graduated mothers were found to have more fillings (restored teeth) in comparison to those who belong to mothers who did not finish their secondary (high school) education. Conclusion. The number of caries-free children in northern Palestine is still far from numbers found in developed countries. There is a real need to make improvements at the level of parents dental health education, application of preventive measures, and dietary habits among preschool children. PMID:25328526

Cellular and molecular mechanisms of dental nociception.  

PubMed

Due, in part, to the unique structure of the tooth, dental pain is initiated via distinct mechanisms. Here we review recent advances in our understanding of inflammatory tooth pain and discuss 3 hypotheses proposed to explain dentinal hypersensitivity: The first hypothesis, supported by functional expression of temperature-sensitive transient receptor potential channels, emphasizes the direct transduction of noxious temperatures by dental primary afferent neurons. The second hypothesis, known as hydrodynamic theory, attributes dental pain to fluid movement within dentinal tubules, and we discuss several candidate cellular mechanical transducers for the detection of fluid movement. The third hypothesis focuses on the potential sensory function of odontoblasts in the detection of thermal or mechanical stimuli, and we discuss the accumulating evidence that supports their excitability. We also briefly update on a novel strategy for local nociceptive anesthesia via nociceptive transducer molecules in dental primary afferents with the potential to specifically silence pain fibers during dental treatment. Further understanding of the molecular mechanisms of dental pain would greatly enhance the development of therapeutics that target dental pain. PMID:23955160

Relationship of Perceived Stress and Dental Caries among Pre University Students in Bangalore City  

PubMed Central

Introduction: Stress can increase the susceptibility to dental caries by four possible mechanisms. Studies show that adolescents tend to more likely develop negative body image, disturbed eating behaviours and high levels of stress. Students report stress, taking and studying for exams being the greatest source of academic stress due to competition and the large amount of content in less time. Aims and Objectives: The objectives were to analyze the caries experience in relation to perceived stress during preuniversity examination period, to estimate the prevalence of dental caries and to calculate SiC (significant caries index) among preuniversity students in Marathahalli, Bangalore city, India. Materials and Methods: This cross-sectional, correlational study involved 210 students (Response rate = 65.37%). The questionnaire consisted of demographic details and Perceived Stress Scale (PSS). Dental caries status was evaluated using the WHO (1997) caries diagnostic criteria for decayed, missing, and filled teeth (DMFT: Dynamical mean field theory). Results: Prevalence of dental caries was 50.48%. Mean DMFT was 1.74 and Sic index was 4.56. The correlation between PSS and caries experience was found to be weak (r=0.389) (p<0.001). Conclusion: Academic stress appears to affect oral health, shown by higher caries experience in high perceived stress score individuals. PMID:25584305

Clinical consequences of untreated dental caries evaluated using PUFA index in orphanage children from India  

PubMed Central

Background: To determine the prevalence and severity of oral condition related to untreated dental caries with PUFA index and to relate period of institutional stay, oral hygiene practice and diet of orphan children to caries experience ratio. Materials & Methods: A cross sectional survey conducted among 488 children of 12-14 years living in 5 different orphanages of Mysore district, India. Data regarding oral hygiene practices and oral health status (PUFA, DMFT, OH I-S and GI) were collected through structured questionnaire and by type III clinical oral examinations. The collected data were processed statistically. Results: The PUFA ratio indicates 21% of decayed component had progressed to pulp involvement and abscess formation. The overall prevalence of PUFA was 37.7%. 31.1% children showed one or more pulpally involved tooth in their oral cavity. Correlation between periods for being the child in the institute to DMFT showed negative value indicting decrease in DMFT as the duration of stay in orphanage increases. Conclusion: The result show oral health condition in orphan children was neglected. Children from this disadvantaged background have shown a high prevalence of dental caries with low dental care utilization. PUFA index is an effective index in evaluating clinical consequences of un-treated caries. How to cite this article: Shanbhog R, Godhi BS, Nandlal B, Kumar SS, Raju V, Rashmi S.

Screening preschool children with toothache: validation of the Brazilian version of the Dental Discomfort Questionnaire  

PubMed Central

Background The Dental Discomfort Questionnaire (DDQ) is an observational instrument intended to measure dental discomfort and/or pain in children under 5 years of age. This study aimed to validate a previously cross-culturally adapted version of DDQ in a Brazilian children sample. Methods Participants included 263 children (58.6% boys, mean age 43.5 months) that underwent a dental examination to assess dental caries, and their parent that filled out the cross-culturally adapted DDQ on their behalf. Exploratory factor analysis (principal component analysis form) and psychometric tests were done to assess instrument’s dimensionality and reliability. Results Exploratory factor analysis revealed a multidimensional instrument with 3 domains: ‘eating and sleeping problems’ (Cronbach’s alpha 0.81), ‘earache problems’ (alpha 0.75), and ‘problems with brushing teeth’ (alpha 0.78). The assessment had excellent stability (weighted-kappa varying from 0.68 to 0.97). Based on the factor analysis, the model with all 7 items included only in the first domain (named DDQ-B) was further explored. The items and total median score of the DDQ-B were related to parent-reported toothache and the number of decayed teeth, demonstrating good construct and discriminant validities. Conclusions DDQ-B was proven a reliable pain assessment tool to screen this group of Brazilian children for caries-related toothache, with good psychometric properties. PMID:24593691

Microstructural studies of dental amalgams using analytical transmission electron microscopy  

NASA Astrophysics Data System (ADS)

Dental amalgams have been used for centuries as major restorative materials for decaying teeth. Amalgams are prepared by mixing alloy particles which contain Ag, Sn, and Cu as the major constituent elements with liquid Hg. The study of microstructure is essential in understanding the setting reactions and improving the properties of amalgams. Until the work reported in this dissertation, optical microscopy (OM), scanning electron microscopy (SEM), and x-ray diffractometry (XRD) were used commonly to analyze amalgam microstructures. No previous systematic transmission electron microscopy (TEM) study has been performed due to sample preparation difficulties and composite structure of dental amalgams. The goal of this research was to carry out detailed microstructural and compositional studies of dental amalgams. This was accomplished using the enhanced spatial resolution of the TEM and its associated microanalytical techniques, namely, scanning transmission electron microscopy (STEM), x-ray energy dispersive spectroscopy (XEDS) and micro-microdiffraction (mumuD). A new method was developed for thinning amalgam samples to electron transparency using the "wedge technique." Velvalloy, a low-Cu amalgam, and Tytin, a high-Cu amalgam, were the two amalgams characterized. Velvalloy is composed of a Agsb2Hgsb3\\ (gammasb1)/HgSnsb{7-9}\\ (gammasb2) matrix surrounding unreacted Agsb3Sn (gamma) particles. In addition, hitherto uncharacterized reaction layers between Agsb3Sn(gamma)/Agsb2Hgsb3\\ (gammasb2)\\ and\\ Agsb2Hgsb3\\ (gammasb1)/HgSnsb{7-9}\\ (gammasb2) were observed and analyzed. An Ag-Hg-Sn (betasb1) phase was clearly identified for the first time. In Tytin, the matrix consists of Agsb2Hgsb3\\ (gammasb1) grains. Fine precipitates of Cusb6Snsb5\\ (etasp') are embedded inside the gammasb1 and at the grain boundaries. These precipitates are responsible for the improved creep resistance of Tytin compared to Velvalloy. The additional Cu has completely eliminated the gammasb2 phase which is the weakest component of amalgams. Ag-Hg-Sn (betasb1) and large grains of Cusb6Snsb5\\ (etasp') are found adjacent to the unreacted alloy particles. Tytin alloy particles contain Cusb3Sn\\ (epsilon) precipitates in a matrix of Agsb3Sn (gamma) and Agsb4Sn\\ (beta). SEM was used to correlate the TEM findings in the context of the general microstructure. The results are in good agreement with those published in the literature. The microstructural details reported here, many of which were not previously available, will help provide insight into the deformation mechanisms of dental amalgams.

Referring periodontal patients: clinical decision making by dental and dental hygiene students.  

PubMed

Referral of periodontal patients requires development of a complex set of decision making skills. This study was conducted to determine criteria used by dental and dental hygiene students regarding the referral of periodontal patients for specialty care. Using mixed methods, a thirteen-item survey was developed to elicit the students' perceptions of their knowledge, confidence regarding managing patients, and clinical reasoning related to periodontal patients. The instrument was administered during the summer prior to (T1) and at the end of the students' final year (T2) of training. Seventy-nine dental students (81 percent of total class) and thirty dental hygiene students (83 percent of total class) completed T1. At T2, forty-two dental (44 percent of total class) and twenty-six dental hygiene students (87 percent of total class) completed the questionnaire. While 90 percent of dental and 96 percent of dental hygiene respondents reported a willingness to refer patients with active disease to specialists, only 40 percent of dental and 36 percent of dental hygiene respondents reported confidence in diagnosing, treating, and appropriately referring such patients. The students' ability to recognize critical disease and risk factors influencing referral was good; however, clinical application of that knowledge indicated a gap between knowledge and applied reasoning. The students' attitudes about the importance of periodontal disease and their perceived competence to identify critical disease risk factors were not significantly related (p>0.05) to correct clinical decisions in the case scenarios. The study concludes that dental and dental hygiene curricula should emphasize both the acquisition and application of knowledge regarding criteria for referral of periodontal patients. PMID:24609346

Dental and dental hygiene students' perceptions of a standardized patient instructor conflict resolution program.  

PubMed

The aim of this study was to examine students' perceptions of the value of a standardized patient instructor conflict resolution program designed to strengthen their communication and confidence during difficult patient conversations. Three cohorts of students at one dental school were part of the study: the dental class of 2013, the dental class of 2014, and the dental hygiene class of 2013. The same groups of students completed surveys immediately following the program and one, two, or three years afterwards. Response rates for the survey immediately after the program were 98 percent (n=99) of the dental class of 2013, 97 percent (n=103) of the dental class of 2014, and 100 percent (n=25) of the dental hygiene class of 2013. Response rates for the subsequent survey were 41.5 percent (n=42) of the dental class of 2013, 74.5 percent (n=79) of the dental class of 2014, and 100 percent (n=25) of the dental hygiene class of 2013. In the results, all students reported a high level of satisfaction in their immediate assessment of the program and its ability to prepare them for conflict situations. They also reported a high level of satisfaction in their retrospective self-assessment of conflict resolution skills. However, their assessment of the program's value and applicability appeared to have diminished over time. This study suggests that the program should continue being a part of both dental and dental hygiene curricula, with more training and guided experiences in self-assessment and perhaps supplemental experiences added.

Targeted p120-Catenin Ablation Disrupts Dental Enamel Development  

E-print Network

Dental enamel development occurs in stages. The ameloblast cell layer is adjacent to, and is responsible for, enamel formation. When rodent pre-ameloblasts become tall columnar secretory-stage ameloblasts, they secrete enamel matrix proteins, and the ameloblasts start moving in rows that slide by one another. This movement is necessary to form the characteristic decussating enamel prism pattern. Thus, a dynamic system of intercellular interactions is required for proper enamel development. Cadherins are components of the adherens junction (AJ), and they span the cell membrane to mediate attachment to adjacent cells. p120 stabilizes cadherins by preventing their internalization and degradation. So, we asked if p120-mediated cadherin stability is important for dental enamel formation. Targeted p120 ablation in the mouse enamel organ had a striking effect. Secretory stage ameloblasts detached from surrounding tissues, lost polarity, flattened, and ameloblast E- and N-cadherin expression became undetectable by immunostaining. The enamel itself was poorly mineralized and appeared to be composed of a thin layer of merged spheres that abraded from the tooth. Significantly, p120 mosaic mouse teeth were capable of forming normal enamel demonstrating that the enamel defects were not a secondary effect of p120 ablation. Surprisingly, blood-filled sinusoids developed in random locations around the developing teeth. This has not been observed in other p120-ablated tissues and may be due to altered p120-mediated cell signaling. These data reveal a critical role for p120 in tooth and dental enamel development and are consistent with p120 directing

Qualitative assessment of the dental health services provided at a dental school in Kerman, Iran.  

PubMed

Increasing the quality of the services provided in a Dental School can raise the satisfaction level of patients and consequently increase the level of their oral health. This study was conducted to evaluate the quality of dental care and services provided to patients referred to a Dental School in Kerman, Iran. In this qualitative study, face-to-face, in-depth interviews were conducted with 41 participants [25 patients (P), 5 nurses (N), 6 dental academic staff (AS), and 5 dental students (S)]. Then, the interviews were transcribed and analyzed, using content analysis of data. Data analysis in qualitative research involves breaking down the data and searching for codes and categories that are then reassembled to form themes. Both positive and negative themes emerged. Positive themes included: good infection control, service accessibility, patient appointments and visits were not assigned on merit, precise examinations, and comprehensive treatment plans. Negative themes included: long wait time, lack of options to pass waiting time, such as newspapers and television, an insufficient number of nurses, and not enough professors for supervision. In addition, the results of this study show that the patients and dental staff have high expectations in relation to dental services, and that implementation of these expectations would increase the overall satisfaction with and the quality of the level of services. Finally, some recommendations for improving services in the Kerman Dental School were given to the managing team of the Dental School. PMID:20027443

Dental health of children: where we are today and remaining challenges.  

PubMed

Dental caries remains the most common disease in man and presents a tremendous health-affecting challenge and fiscal burden to both developed and underdeveloped countries. Changing demographics including increased number of ethnic minorities, cultural practices and diet, the number of children living in poverty or near poverty, and the special needs of medically compromised children have made solutions more complex and evasive. Systemic and topical fluoride contacts remain the most cost-effective public health response to preventing caries among children. The time-honored impact of reducing sugars and carbohydrates in the diet and improving oral hygiene practices also remain essential. New technology has the potential of offering remineralization strategies. The dental profession is challenged to be proactive in identifying alternatives and implementing new and creative ways to embrace underserved children and improve their access to care including trauma prevention. The impact on families and society, including financial and general well-being, due to poor oral health is significant. Lower income families absorb disproportionately the effect of dental diseases due to lack of education, food availability and selection, and access to early preventive care. PMID:18524274

Electrochemical impedance spectroscopy in understanding the influence of ultrasonic dental scaling on the dental structure-dental filling interface.  

PubMed

The purpose of this study was to investigate the effect of ultrasonic scaling on teeth restored with a light-cured resin. Ultrasonic scaling is a very popular periodontal therapy among dentists, and used for the removal of dental plaque and calculus in order to reduce and eliminate inflammation. Given the fact that most ultrasonic devices are used at high frequencies to perform scaling, undesirable consequences, such as loss of adhesion and increase in surface roughness, may occur in teeth that have been restored with light-cured resins. Electrochemical impedance spectroscopy (EIS) and scanning electron microscopy were used to investigate the effects of ultrasonic treatments at the dental material-hard dental tissue interface. After ultrasonic scaling, EIS measurements were performed on a human tooth that had been restored with a light-cured resin filling. The data were analyzed and the influence of ultrasound was shown after visualization of the hard dental tissues and the dental material as equivalent electrical circuits. The study revealed, through EIS measurements, that ultrasonic scaling affected the resistance of the light-cured resin filling and dentin, whereas the enamel was affected only slightly. Scanning electron microscopy revealed an increase in roughness of the dental material. PMID:25371134

Dental Pulp Testing: A Review  

PubMed Central

Dental pulp testing is a useful and essential diagnostic aid in endodontics. Pulp sensibility tests include thermal and electric tests, which extrapolate pulp health from sensory response. Whilst pulp sensibility tests are the most commonly used in clinical practice, they are not without limitations and shortcomings. Pulp vitality tests attempt to examine the presence of pulp blood flow, as this is viewed as a better measure of true health than sensibility. Laser Doppler flowmetry and pulse oximetry are examples of vitality tests. Whilst the prospect is promising, there are still many practical issues that need to be addressed before vitality tests can replace sensibility tests as the standard clinical pulp diagnostic test. With all pulp tests, the results need to be carefully interpreted and closely scrutinised as false results can lead to misdiagnosis which can then lead to incorrect, inappropriate, or unnecessary treatment.

Maternal dental caries and pre-term birth: results from the EPIPAP study.  

PubMed

OBJECTIVE. The aim of this study was to analyse the association between maternal dental caries and pre-term birth (PTB), with a particular focus on the infection-suspected causes of pre-term births. MATERIALS AND METHODS. A secondary analysis was performed on data from the EPIPAP study, a French multi-centre case-control study. Cases were 1107 women giving birth to a singleton live-born infant before 37 weeks of gestation and controls were 1094 women delivering at 37 weeks or more. A sub-group of cases was defined as women with spontaneous labour and/or pre-term premature rupture of membranes (PPROM, n = 620). A full-mouth dental examination was performed after delivery. The main factor of interest was the presence of decay on at least one tooth. RESULTS. Crude associations between presence of tooth decay and PTB or spontaneous PTB/PPROM were significant (OR = 1.21 [1.01-1.45] and OR = 1.25 [1.01-1.55], respectively). After adjustment for two sets of potential confounders (four pre-term birth risk factors and four social characteristics), for periodontitis status and for inter-examiner variability, tooth decay was not significantly associated with either PTB or spontaneous PTB/PPROM (aOR = 1.10 [0.91-1.32] and aOR = 1.14 [0.91-1.42], respectively). CONCLUSIONS. This study failed to demonstrate a significant association between tooth decay and pre-term birth. However, future well-designed studies are needed to further assess the link between dental caries and adverse pregnancy outcomes. PMID:21375427

CO2 lasers can be operated at high laser pulse repetition rates for the rapid and precise removal of dental decay. Excessive heat accumulation and peripheral thermal damage is a concern when using high pulse repetition rates. Peripheral thermal damage can adversely impact the mechanical strength of the irradiated tissue, particularly for dentin, and reduce the adhesion characteristics of the modified

Sudden hearing loss after dental treatment.  

PubMed

A 66-year-old man presented with impaired balance, tinnitus, sensation of blockage, and hearing loss in his left ear, which developed after dental treatment for dental pain 4 days previously. Treatment of the carious left upper second molar tooth had included pulp extirpation, canal expansion, and tooth filling under local anesthesia with articaine and epinephrine. Impaired balance decreased spontaneously within 3 days of dental treatment, but tinnitus and hearing loss persisted. Pure tone audiogram showed profound sensorineural hearing loss in the left ear, with a downslope from 40 to 100 dB, and an abnormal speech discrimination score (50%). Treatment included intravenous prednisolone, intratympanic dexamethasone, and oral betahistine and trimetazidine. The patient had improved hearing and resolution of tinnitus. Sudden hearing loss is rare after dental treatment, and awareness of this complication may prompt early referral for treatment and may improve recovery and prognosis. PMID:23642550

Connecting dental education to other health professions.  

PubMed

The health care delivery system is poised for substantial change in the coming years. The foremost vector driving this change is economics. However, use of evidence-based principles of practice and a high desire, if not a national mandate, for increased quality in health care delivery are also very important factors. Nestled within this large national health care debate are a set of issues that directly impact dental education and practice. Among them is the potential impact of expanded intraprofessional and interprofessional collaborations among dentists, dental therapists, dental hygienists, and nurse practitioners, among others, in search of better oral and general health care for all Americans. This article explores many of the issues involved in this possible transition with special reference to the impact of the changes on dental education. PMID:22262549
