    Background: Pro-inflammatory markers are seen to increase in inflammatory diseases like periodontitis. Detecting an increase in these markers is one of the diagnostic modality. One such marker, which can be detected, is the ceruloplasmin. Ceruloplasmin induces hypoxia and generates oxygen radicals at the site of aggressive periodontitis. It also causes a state of hypoferremia leading to increase in the natural resistance of the body. The aim of this study was to evaluate the serum levels of cerruloplasmin in both aggressive and chronic periodontitis patients. Materials and Methods: Blood samples were collected from aggressive periodontitis patients (n = 20), chronic periodontitis patients (n = 20) and periodontally healthy patients (n = 20). The serum was extracted from all the blood samples and ceruloplasmin levels were spectroscopically evaluated through a new kinetic method, which used a norfloxacin based reagent. Results: Serum ceruloplasmin levels were found to be significantly higher in aggressive periodontitis patients (P > 0.05) than in chronic periodontitis patients (P > 0.05) even though increase in the level of ceruloplasmin was found in chronic periodontitis. Periodontally healthy patients did not show increase in the levels of serum ceruloplasmin. The levels of serum ceruloplasmin also increased with the disease severity whose manifestations were increased bleeding on probing, increased pocket depth and increased attachment loss. Conclusion: Serum ceruloplasmin levels increased in both aggressive and chronic periodontitis patients, but more in aggressive periodontitis patients making it a potential marker for diagnosis of periodontitis.

    Background: Oral exfoliative cytology includes the study and interpretation of the features cells exfoliated from the oral mucosa. The aim of this study was to analyze cytological changes in the periodontal pocket of patients with different clinical stages of aggressive periodontitis (AP) and chronic periodontitis (CP). Materials and Methods: Patients aged 24–54 years, of whom 41 were diagnosed with AP, 40 with CP, sub-classified as mild, moderate and severe periodontitis, and 40 healthy individuals who were the control group. Samples of the epithelium of the periodontal pocket were taken for the cytological study. Results: Superficial and intermediate cell values were significantly greater in patients with AP than in patients with CP or the control group. Histiocyte number was higher in patients with CP than in those with AP, and differed significantly in both types of periodontitis compared to the control group. There were significant differences in polymorphonuclear neutrophil leukocytes when both types of periodontitis were compared to the control group. Microbial flora was statistically higher in patients with CP, and there were differences between patients with periodontitis and the control group. Conclusions: The cytological study demonstrated that patients with AP had greater tissue damage, shown by the increase in intermediate and superficial cells of the epithelium of the periodontal pocket compared to the group of healthy subjects and to a lesser extent, to patients with CP. Only superficial cells made it possible to differentiate the sub-stages of the disease. PMID:25395766

    Objectives: The aim of this study was to determine the cementum thickness in the first molars of patients with localized aggressive periodontitis (LAP) compared to healthy individuals. Materials and Methods: This case-control study compared eight first molar teeth affected by LAP with eight third molar teeth of healthy individuals. The teeth were disinfected by immersion in 10% buffered formalin solution for three days and were then sectioned. External mesial root surfaces (middle one-third) were evaluated under a stereomicroscope by a blinded pathologist to determine the mean thickness of cementum. SPSS software (version 16.0) and t-test were used for statistical analysis. Results: Histological examination revealed a significant difference between the two groups in terms of the amount of cementogenesis (P<0.001) .The thickness of cementum was higher in the control group (105.16±11.5 μm) than in LAP patients (86.44±7.3 μm). Conclusion: This study demonstrated the presence of cementum hypoplasia in mesial root surfaces of first molars affected by LAP. PMID:26877730

    Background: The success of combined periodontal and orthodontic approach in the treatment of aggressive periodontitis patients with the pathologic extruded anterior teeth is a main concern and stability of the treatment results is an important factor to evaluate the treatment. The present study investigated the periodontal parameters at the end of the orthodontic treatment in patients with the aggressive periodontitis. Materials and Methods: Eight patients with an aggressive periodontal disease, extruded maxillary incisors, infrabony defects and probing depth of ≥5 mm were enrolled in this clinical trial (before, after). After periodontal therapy, orthodontic treatment was carried out for intrusion and alignment of teeth. Plaque index (PI), probing pocket depth (PPD), distance between incisal edge and interdental papilla, root length (RL), and defect dimensions (depth and width) were examined at the end of treatment and three as well as 6 months afterward. The data were subjected to repeated measure ANOVA test. P < 0.05 was considered as significant. Results: There was statistically significant decrease in PPD, PI, and depth of the defects during T0, T3 and T6 (P < 0.05). No significant differences were observed in the RL and distance between incisal edge and interdental papilla (P = 0.95). Furthermore, width of the defects demonstrated significant decrease up to T3 (P = 0.042) while no significant changes from 3 months to 6 months were noted (P = 0.59). Conclusion: The results showed that combined periodontal and orthodontic approach would be a successful treatment with acceptable stability in the case of regular follow-up visits and controlled oral hygiene habits.

    2016-01-01

    Case Description. This case report describes the successful management of a left mandibular first molar with a combined periodontic-endodontic lesion in a 35-year-old Caucasian woman with aggressive periodontitis using a concerted approach including endodontic treatment, periodontal therapy, and a periodontal regenerative procedure using an enamel matrix derivate. In spite of anticipated poor prognosis, the tooth lesion healed. This case report also discusses the rationale behind different treatment interventions. Practical Implication. Periodontic-endodontic lesions can be successfully treated if dental professionals follow a concerted treatment protocol that integrates endodontic and periodontic specialties. General dentists can be the gatekeepers in managing these cases. PMID:27418983

    2013-01-01

    Background. Proinflammatory and anti-inflammatory cytokines play a key role in the pathogenesis of periodontal diseases. Secretion of bioactive IL-35 has been described by T regulatory cells (Tregs) and is required for their maximal suppressive activity. Tregs are involved in the modulation of local immune response in chronic periodontitis patients. Objective. Hence, the present study was aimed to investigate the expression of IL-35 mRNA in chronic periodontitis and aggressive periodontitis patients. Materials and Methods. The present study was carried out in 60 subjects, which included 20 chronic periodontitis patients, 20 aggressive periodontitis patients, and 20 periodontally healthy controls. IL-35 mRNA expression in gingival tissue samples of all subjects was semiquantitatively analyzed using Reverse Transcriptase Polymerase Chain Reaction (RT-PCR). Results. The present study demonstrated the expression of IL-35 mRNA in gingival tissues of all the three groups. IL-35 mRNA expression was highest in chronic periodontitis subjects (6.87 ± 2.32) as compared to the aggressive periodontitis group (4.71 ± 1.43) and least seen in healthy patients (3.03 ± 1.91). Conclusion. The increased expression of IL-35 in chronic and aggressive periodontitis suggests its possible role in pathogenesis of periodontitis. Future studies done on large samples with intervention will strengthen our result. PMID:24376289

    The aim of the research was to study sensitivity of specific microorganisms from the periodontal pockets of patients with rapidly progressive periodontal disease to Taromentine. 95 patients aged 21 to 35 years (50 women (52,6+/-33,62) and 45 men (47,36+/-3,62)) with rapidly progressive form of periodontal desease were observed. Porphiromonas gingivalis was identifide in 83 out of 95 patients (87,36+/-2,06). Prevotella intermedia - in 31 patients (32,6+/-2,750); Actinobacillus actinomycetemcomitans - in 23 patients (24,2+/-2,050); Bacteroides forsythus - in 19 patients (20,0+/-2,360); Treponema denticola - in 16 patients (16,84+/-2,190); Candida - in 11 patients (11,57+/-1,80). The sensitivity of all cultures to Taromentine was investigated: 134 (77,9+/-1,89) out of 183 identified markers demonstrated sensitivity to Taromentine. Demostrated sensitivity to Taromentine: 64 (37,2+/-1,06) out of 83 identified cultures of Porphiromonas gingivalis, 24 (13,95+/-1,85) out of 31 identified cultures of Prevotela intermedia, 18 (10,47+/-1,05) out of 23 identified cultures of Actinobacillus actinomycetemcomitans, 15 (8,7+/-1,86) out of 19 identified cultures of Bacteroides forsythus, and 13 (7,84+/-1,09) out of 16 identified cultures of Treponema denticola. Totally 38 (22,1+/-1,59) out of 172 identified periodontal markers demonstrated resistence to Taromentine. The results of analysis showed that Taromentine could be recommended in complex treatment of periodontal diseases. PMID:19430039

    Background: There is a strong evidence that genetic as well as environmental factors affect the age of onset, severity and lifetime risk of developing periodontitis. The objective of the present study was to compare and to evaluate the association between interleukin (IL)-1α(-889) and gene polymorphisms in patients with generalized aggressive periodontitis, chronic periodontitis and healthy controls. Materials and Methods: A total of 60 Indian patients, with 20 aggressive periodontitis, 20 chronic periodontitis and 20 healthy controls were recruited for this study. From each patient, a volume of 2 ml of blood was collected by venipuncture in the ante-cubital fossa and was stored in sodium EDTA vacutainers and was used for genotyping assays with the polymerase chain reaction restriction fragment length polymorphism technique. Clinical parameters such as oral hygiene index, gingival index and clinical attachment loss (CAL) were evaluated for each patient. Genotype distribution between different groups were analyzed using Chi-square test. A P = 0.05 or less was set for significance. Results: The mean oral hygiene index was 3.7 ± 0.86 and 3.25 ± 0.30 for chronic and aggressive periodontitis cases respectively. The CAL was 4.29 ± 0.63 mm for chronic periodontitis and 6.44 ± 0.57 mm for aggressive periodontitis. Homozygous genotype 2,2 was more predominant in cases of aggressive periodontitis whereas in chronic periodontitis, heterozygous genotype 1,2 was more predominant when compared with others (P < 0.001). Odds ratio for aggressive versus chronic periodontitis was calculated as 6.2 (95% confidence interval 6.019-7.892). Conclusion: The results of the present study support a positive association between aggressive periodontitis and the presence of the IL-1α-889, allele 2 polymorphism in Indian patients.

    A 34 years old male patient was referred to our clinic for restorative dental treatment. During detailed consultation and dental examination a relatively rare form of periodontal disease had been diagnosed. Intraoral examination included recording of dental and periodontal status. Based on patient's dental history, measurements of probing pocket depths (PPD), clinical attachment level (CAL), and also the X-ray findings, Localized Aggressive Periodontitis (LAP) unknown by the patient was diagnosed. After patient's consent the comprehensive treatment plan covered the dental prevention, periodontal non-surgical and surgical therapy and rehabilitation. The treatment started with oral hygienic instruction, motivation then supra- and subgingival scaling and rootplaning. Later extraction and elective root canal treatment were performed, followed by open flap periodontal surgery combined with hemisection of two molars. After a full mouth conservative restorative therapy, function and esthetics were restored by fix dental prostheses. This case is a good example to underline the importance of periodontal examination during the dental screening and dental status recording for each patients showing up at dental clinics. Otherwise in many cases this asympthomatic disease can remain undetected. PMID:26863818

    Background: With the advent of DNA-based culture-independent techniques, a constantly growing number of Selenomonas phylotypes have been detected in patients with destructive periodontal diseases. However, the prevalence levels that have been determined in different studies vary considerably. Aim: The present study was undertaken to detect and compare the presence of Selenomonas sputigena in the subgingival plaque samples from generalized aggressive periodontitis (GAP), chronic generalized periodontitis, and periodontally healthy patients using conventional polymerase chain reaction (PCR) technique. Materials and Methods: A total of 90 patients were categorized as periodontally healthy individuals (Group I, n = 30), chronic generalized periodontitis (Group II, n = 30), and GAP (Group III, n = 30). The clinical parameters were recorded and subgingival plaque samples were collected. These were then subjected to conventional PCR analysis. Statistical Analysis Used: Kruskal–Wallis ANOVA test was used for multiple group comparisons followed by Mann–Whitney U-test for pairwise comparison. Results: On comparison between three groups, all the clinical parameters were found to be statistically highly significant. Comparing Groups I-II and I-III, the difference in detection was found to be statistically highly significant whereas in Groups II-III, it was statistically nonsignificant. On comparison of S. sputigena detected and undetected patients to clinical parameters in various study groups, the difference was found to be nonsignificant. Conclusion: S. sputigena was found to be significantly associated with chronic and aggressive periodontitis. Although the difference in its detection frequency in both groups was statistically nonsignificant when compared clinically, S. sputigena was more closely associated with the GAP. PMID:27563202

    CRP is a plasma protein that reflects a measure of the acute phase response to inflammation and is one of the markers of choice in monitoring this response. CRP can be used for the prediction and early detection of periodontal disease. The aim of this study was to compare and evaluate the systemic levels of CRP in the peripheral blood samples of patients with chronic and aggressive periodontitis, gingivitis, and gingival recessions and compare them with periodontal clinical parameters. All patients (N = 158) were examined prior to the initiation of periodontal treatment. Patients were divided into four groups. Group A consisted of 26 patients with aggressive periodontitis, Group B consisted of 111 patients with chronic periodontitis, Group C consisted of 13 patients with gingivitis, and Group D consisted of 8 patients with gingival recessions. Our study results indicate that CRP levels increase subsequently with the severity of the periodontal disease and that the bleeding on probing index showed much better positive correlation with the CRP levels compared to the pocket depth index in both periodontitis patients groups, especially in aggressive periodontitis patients.

    Oro-facial clefts are one of the most common birth defects and may be associated with other genetic anomalies. Aggressive periodontitis is a rare condition that progresses rapidly, but affects only a small percentage of the population. Most of the cases of aggressive periodontitis are familial. Even though, literature has documented the association of various genetic disorders with aggressive periodontitis, the aggressive periodontitis in patients with isolated cleft lip (CL) have never been addressed. Here, we report a rare case of isolated CL with generalized aggressive periodontitis. The concomitant presentation of isolated CL with aggressive periodontitis in an individual has clinical significance for multi-disciplinary care. PMID:25810600

    genetic profile, currently do not exist. Genetic markers have the potential to be implemented as screening tools to identify subjects at risk. This approach may significantly enhance treatment outcome through the early detection and treatment of affected subjects, as well as using future approaches based on gene therapy. At present, the treatment of this disease is directed toward elimination of the subgingival bacterial load and other local risk factors. Adjunctive use of appropriate systemic antibiotics is recommended and may contribute to a longer suppression of the microbial infection. Other aggressive forms of periodontal diseases occur in patients who are affected with certain systemic diseases, including the leukocyte adhesion deficiency syndrome, Papillon-Lefèvre syndrome, Chediak-Higashi syndrome and Down syndrome. Management of the periodontal component of these diseases is very challenging. Acute gingival and periodontal lesions include a group of disorders that range from nondestructive to destructive forms, and these lesions are usually associated with pain and are a common reason for emergency dental consultations. Some of these lesions may cause a rapid and severe destruction of the periodontal tissues and loss of teeth. Oral infections, particularly acute infections, can spread to extra-oral sites and cause serious medical complications, and even death. Hence, prompt diagnosis and treatment are paramount.

    Enlargement of the gingiva can be due to various causes. Most prevalent are the inflammatory type and drug-induced type of gingival hyperplasia. However, sever enlargement associated with an aggressive type of periodontitis is an infrequent finding. Reported here is a case of a female patient aged 18 years who presented with severe enlargement of the maxillary and mandibular gingiva. Examination revealed enlargement extending up to the incisal edge of all the teeth and also an associated generalized loss of attachment with radiographic evidence of reduced bone height resembling an aggressive type of periodontitis. There were no associated systemic signs and symptoms or any family history except that there was generalized vitiligo of the skin and oral mucous membrane. The case was treated by gross electrosection of the gingiva.

    The aim of this study was to determine the frequency of isolation of Actinobacillus actinomycetemcomitans (Aa) in 100 patients with chronic periodontitis, 14 patients with aggressive periodontitis, 142 pre-school children with gingivitis and 134 periodontally healthy subjects. Samples of subgingival plaque were taken using sterilized paper points introduced into periodontal pockets or gingival crevice for 60 seconds and inoculated on TSBV agar, which was incubated under anaerobiosis at 37°C, for 4 days. Microbial identification was performed through biochemical methods and morphocellular and morphocolonial analysis. Aa was detected in 40.3% of healthy subjects, 68% of patients with chronic periodontitis, 92.86% of patients with aggressive periodontitis and 40.14% of children with gingivitis. The rate of recovery of Aa in the tested human groups proved to be higher than previously reported and in agreement with participation of this facultative anaerobe as a member of native microbiota of the periodontium and its relation with aggressive and chronic periodontitis in Brazil.

    Intrabony periodontal defects present a particular treatment problem, especially in patients with generalized aggressive periodontitis (G-AgP). Regenerative procedures have been indicated for this clinical situation. The aim of this study was to compare treatment outcomes of intrabony periodontal defects with either anorganic bone matrix/cell binding peptide (ABM/P-15) or guided tissue regeneration (GTR) in patients with G-AgP. Fifteen patients, with two intrabony defects ≥3 mm deep, were selected. Patients were randomly allocated to be treated with ABM/P-15 or GTR. At baseline and at 3 and 6 months after surgery, clinical and radiographic parameters and IL-1β and IL-6 gingival fluid concentrations were recorded. There was a significant probing pocket depth reduction (p<0.001) for both groups (2.27 ± 0.96 mm for ABM/P-15 group and 2.57 ± 1.06 mm for GTR group). Clinical attachment level gain (1.87 ± 0.94 mm for ABM/P-15 group and 2.09 ± 0.88 mm for GTR group) was also observed. There were no statistically significant differences in clinical parameters between the groups. The radiographic bone fill was more expressive in ABM/P-15 group (2.49 mm) than in GTR group (0.73 mm). In subtraction radiographs, the areas representing gain in density were 93.16% of the baseline defect for ABM/P-15 group versus 62.03% in GRT group. There were no statistically significant differences in inter-group and intra-group comparisons with regards to IL-1β and IL-6 quantification. Treatment of intrabony periodontal defects in patients with G-AgP with ABM/P-15 and GTR improved significantly the clinical outcomes. The use of ABM/P-15 promoted a better radiographic bone fill.

    Aggressive periodontitis is characterized by a rapid and severe periodontal destruction in young systemically healthy subjects. A greater prevalence is reported in Africans and African descendent groups than in Caucasians and Hispanics. We first fine mapped the interval 1q24.2 to 1q31.3 suggested as containing an aggressive periodontitis locus. Three hundred and eighty-nine subjects from 55 pedigrees were studied. Saliva samples were collected from all subjects, and DNA was extracted. Twenty-one single nucleotide polymorphisms were selected and analyzed by standard polymerase chain reaction using TaqMan chemistry. Non-parametric linkage and transmission distortion analyses were performed. Although linkage results were negative, statistically significant association between two markers, rs1935881 and rs1342913, in the FAM5C gene and aggressive periodontitis (p = 0.03) was found. Haplotype analysis showed an association between aggressive periodontitis and the haplotype A-G (rs1935881-rs1342913; p = 0.009). Sequence analysis of FAM5C coding regions did not disclose any mutations, but two variants in conserved intronic regions of FAM5C, rs57694932 and rs10494634, were found. However, these two variants are not associated with aggressive periodontitis. Secondly, we investigated the pattern of FAM5C expression in aggressive periodontitis lesions and its possible correlations with inflammatory/immunological factors and pathogens commonly associated with periodontal diseases. FAM5C mRNA expression was significantly higher in diseased versus healthy sites, and was found to be correlated to the IL-1β, IL-17A, IL-4 and RANKL mRNA levels. No correlations were found between FAM5C levels and the presence and load of red complex periodontopathogens or Aggregatibacter actinomycetemcomitans. This study provides evidence that FAM5C contributes to aggressive periodontitis. PMID:20383335

    Aggressive periodontitis is diagnosed mainly by clinical and radiographic examination. Diagnosis in the primary dentition indicates a choice between conservative and radical treatment that involves extractions, depending on the severity of the case. The purpose of this report was to present a case of aggressive periodontitis in a systemically healthy child and to discuss the periodontal and orthodontic aspects. A 7-year-old girl presented with bleeding on probing of approximately half of the dentition, deep periodontal pockets around all primary molars, and increased tooth mobility. An individual oral hygiene program was initiated. The primary maxillary right molar and all primary mandibular molars were extracted, and clear vacuum-formed removable retainers were fabricated and used as space maintainers. The patient was followed longitudinally for 2 years, and no space loss was recorded. Clear vacuum-formed removable retainers mainly involve occlusal crown attachment and, therefore, decrease the risk of plaque accumulation, gingival irritation, and aggressive periodontitis in the permanent dentition.

    Polymorphisms in IL-1 gene have been suggested to influence transcription of IL-1α and IL-1B and thereby the pathophysiology of periodontitis. Using genotyping IL-1 test, a pilot study was conducted on 32 Syrian patients with aggressive periodontitis (AgP) and 35 healthy controls to investigate the association between the IL-1α(−889), IL-1B(+3953) gene polymorphisms and AgP among schoolchildren. The results revealed a similar distribution of genotypes between patients and controls, and did not support an association between IL-1 gene polymorphisms and AgP, however, the association was significant in male patients only. To determine and confirm any susceptible or resistant genes for AgP, future studies should use many target genes and well-defined related periodontal outcomes. PMID:22203911

    Localized aggressive periodontitis (LAgP) is a complex multifactorial periodontal disease to which genetic factors are thought to predispose individuals. Interleukin-1 (IL-1) and tumor necrosis factor-alpha (TNF-alpha) are potent immunomodulators and proinflammatory cytokines that have been implicated in the pathogenesis of autoimmune and infectious diseases and proposed to be risk factors for LAgP. Our aim was to investigate IL-1 alpha (+4845), IL-1 beta (+3954), and TNF-alpha (-308) gene polymorphisms in Turkish LAgP patients. We genotyped 31 LAgP patients and 31 healthy controls for IL-1alpha(+4845), IL-1beta(+3954), and TNF-alpha(-308) using standard PCR amplification followed by restriction enzyme digestion and gel electrophoresis. Higher prevalence of heterozygosity for IL-1alpha(+4845) was found in cases (65%) when compared to controls (35%) (P < 0.05). While homozygous allele 1 of IL-1beta(+3954) was the most frequent genotype in cases (62%), no controls were homozygous for this allele (P < 0.001). Homozygous allele 1 was the most common TNF-alpha genotype in both groups, however no significant difference in TNF-alpha genotypes was found between groups. In conclusion, in this Turkish population, susceptibility to LAgP is increased by heterozygosity for allele 1 of IL-1alpha(+4845) or homozygosity for allele 1 of IL-1beta(R+3954). Moreover, IL-1 gene polymorphisms appear to have a role in susceptibility to LAgP, and the above-mentioned genotypes could be an important risk factor for LAgP in the Turkish population.

    Background: IL-1 cytokines have central roles in the pathogenesis of periodontal disease. Polymorphism in the locus +3954 (C/T) of the human IL-1B gene has been shown to affect the levels of this cytokine. Aim: The aim of the present study was to investigate the association between the IL-1 B (+3954) gene polymorphism and the occurrence of different clinical forms of periodontitis. Materials and Methods: Genomic DNA was obtained from 90 individuals and amplified using the PCR with specific primers flanking the locus +3954 of IL-1B. PCR products were submitted to restriction endonuclease digestion and analyzed by gel electrophoresis, allowing for the determination of the genotypes and detection of the polymorphism. Statistical Analysis: Fisher's exact test was used for comparing the frequency of genotype distributions between groups. Results: The chronic periodontitis group displayed a higher percentage of T alleles (38%) when compared to the aggressive periodontitis group (20%) and to the control group (19%). Conclusion: Our study data states that polymorphism in the locus +3954 of IL-1B gene could be a risk factor for chronic periodontitis in a sample of Indian population of Karnataka state.

    Here we report a case of generalized aggressive periodontitis treated with periodontal therapy including adjunct antimicrobial therapy and periodontal surgery. The patient was a 22-year-old woman who presented with the chief complaint of gingival recession. Baseline examination revealed generalized plaque deposition and gingival inflammation. Thirty-nine percent of the sites had a probing depth (PD) of 4-6 mm and 2% a PD of ≥7 mm; 63% exhibited bleeding on probing (BOP). Radiographic examination revealed vertical bone loss in the molars and horizontal bone loss in other teeth. Microbiological examination of subgingival plaque revealed the presence of Aggregatibacter actinomycetemcomitans and Tannerella forsythia. Oral health-related quality of life was assessed as a measure of patient-reported outcome. Based on a clinical diagnosis of generalized aggressive periodontitis, initial periodontal therapy and adjunct antimicrobial therapy were implemented. After reducing inflammation and subgingival bacteria, open flap debridement was performed for teeth with a PD of ≥4 mm. Reevaluation showed no sites with a PD of ≥5 mm, a minimal level of BOP, and a marked reduction in the level of the targeted periodontal pathogens. The patient's oral health-related quality of life was slightly worsened during supportive periodontal therapy (SPT). Implementation of adjunct antimicrobial therapy targeting periodontal pathogens and subsequent periodontal surgery resulted in improvement in periodontal and microbiological parameters. This improvement has been adequately maintained over a 2-year period. However, additional care is necessary to further improve the patient's oral health-related quality of life during SPT.

    This prospective longitudinal 3-year study compared clinical parameters and implant success rates of removable superstructures supported by both teeth and implants in patients with treated generalized aggressive periodontitis (GAP) and of cemented, implant-retained fixed superstructures in periodontally healthy patients. A total of 17 partially edentulous patients with 54 implants took part in the study. Nine patients with treated GAP received removable superstructures according to the Marburg double crown system, and eight periodontally healthy patients received fixed superstructures. Teeth were examined 2 to 4 weeks before extraction of the nonretainable teeth (baseline) and 3 weeks after insertion of the definitive abutments. Every 3 months over a 3-year period, clinical parameters were recorded and the composition of the subgingival microflora was determined. Intraoral radiographs were obtained at baseline, just after insertion of the superstructure, and 1 and 3 years later. Both groups showed mean plaque and gingival indices below 0.43 at implants and teeth. Mean probing depths around implants increased by approximately 0.7 mm and remained virtually constant for the teeth. Mean attachment loss at implants was 0.9 mm in GAP patients and 0.5 mm in healthy patients. The morphologic distribution of microorganisms in both groups showed healthy conditions. Moderate bone loss at teeth and implants was registered. Implant success rates were 100% in the healthy patients and 97.6% in the GAP patients. No significant differences were seen in the results between the groups.

    Gingival enlargement, one of the manifestations of gingival and periodontal disease, is also known as gingival overgrowth. Idiopathic gingival enlargement is a rare gingival overgrowth, which is of an undetermined cause. This unknown etiology has now been linked to specific genes and idiopathic gingival enlargement is at times referred to as hereditary gingival enlargement. This condition is a benign, slow growing proliferation of gingival tissues. Aggressive periodontitis is the rapid form of periodontal disease which is characterized by extensive periodontal tissue destruction, increased host-susceptibility toward periodontal disease progress and a genetic predilection toward disease occurrence. We present a rare case of idiopathic gingival fibromatosis associated with generalized aggressive periodontitis in a young female. The patient presented with classic clinical and radiographic presentation associated with gingival enlargement and aggressive periodontitis. The diagnosis was then confirmed by histopathological and neutrophil functions tests. PMID:24872638

    Background It was hypothesized that if periodontal infections predispose low birth weights and premature birth, then such outcomes should be apparent when the mother has aggressive periodontitis (AgP). Methods Birth weight data were collected by questionnaire from females with AgP, their periodontally healthy siblings, and unrelated periodontally healthy women. Both prospective and retrospective birth outcome data were used. Because many of the periodontal evaluations were performed after the births, there were incomplete data regarding most of the risk factors for low birth weight. We determined associations between mothers’ periodontal diagnoses and clinical variables and the reported birth weights. Results There were no significant differences in mean birth weights of babies born to control subjects or AgP patients. This was true whether all the births were considered or only those reported <1 or 2 years before periodontal examination. For periodontally healthy controls, 13.2% of babies born to siblings of AgP patients and 12.8% of babies born to unrelated mothers weighed <2,500 g, whereas 9.9% of those born to mothers with generalized AgP and 10.3% of those born to mothers with localized AgP weighed <2,500 g. Conclusions Because of the relative rarity of AgP in the population, and attendant difficulties in performing a prospective study of its association with pregnancy outcomes, we used a compromised approach using prospective data as well as weaker retrospective data assuming that disease onset was likely before the births. Our results, within the limitations of this approach, indicate no evidence that AgP in the mother predisposes low birth weights. AgP has many unique biologic characteristics that differentiate it from chronic forms of periodontal disease, and the possible lack of its association with birth weight may be another such characteristic.

    Background: Aggressive periodontitis (AgP) has been associated with polymorphonuclear leukocyte's (PMNL) dysfunction and periodontal pathogens possess variety of virulence factors that can impair PMNL's function. This study investigated the possible association between defective neutrophil adhesion and β2 -integrin expression and defective neutrophil migration and actin polymerization level in the peripheral blood of neutrophils from the patients with AgP. Materials and Methods: A total of 30 individuals both male and female, age ranges between 13 – 48 years, were included in the study. Healthy controls (group I, n=10), chronic periodontitis (ChP) (group II, n=10), and AgP (group III, n=10), all without any systemic diseases and non-smokers, were recruited. Peripheral blood samples were taken and β2 -integrin expression and actin polymerization levels were estimated by using fluorescence activated cell sorter analysis. Results: In AgP cases, both average values (β2 -integrin and actin level) were significantly less than that of normal subjects (<0.001). But for ChP cases, only the average value of actin level is significantly lower than that of normal subjects (<0.025). Conclusion: Lower β2 -integrin expression in the AgP cases signifies lower neutrophil adhesion in AgP cases than normal, and the lower average value of actin polymerization for the AgP cases suggest lower migration capacity of neutrophils in AgP cases than normal.

    Background: Aggressive periodontitis is a characterized by rapid attachment loss, bone destruction and familial aggregation. Platelet-rich plasma (PRP) has been proposed to promote regeneration of the lost periodontal tissues. The aim of this study was to evaluate and compare the efficacy of PRP combined with hydroxyapatite (HA) graft in the treatment of intra-bony defects in localized aggressive periodontitis (L-AgP) patients. Materials and Methods: Ten L-AgP patients having bilateral intra-bony defect ≥2 mm and probing depth (PD) ≥6 mm were randomly treated either with the PRP/HA graft or HA graft alone. The clinical (plaque control record, bleeding on probing index, PD, and relative attachment level [RAL]), and radiographic parameters (size of the bone defect) were recorded pre- and post-operatively at 3, 6, and 12 months. Results: After 12 months, for both maxillary and mandibular arches, the mean PD decrease was significantly more (P < 0.05) for the test group than the control group (3.2 mm vs. 1.9 mm and 3.6 mm vs. 1.9 mm, respectively). Furthermore, the mean RAL decrease in both maxillary and mandibular arches was significantly more (P < 0.05) for the test group than the control group (3.0 mm vs. 1.2 mm and 3.1 mm vs. 1.4 mm, respectively). Radiographically, the test group showed significantly more defect fill as compared with the control group. Conclusion: Both treatments provided significant improvements in clinical and radiographic parameters in a 12-month postoperative period. PRP/HA group presented superior results regarding PD reduction, clinical attachment gain and radiographic bone fill than HA group. PMID:25395757

    Background Matrix metalloproteinases (MMPs) are a family of host-derived proteinases reported to mediate multiple functions associated with periodontal destruction and inflammation. We have previously reported high MMP levels in African-American children with localized aggressive periodontitis (LAP). However, little is known about MMP reductions in gingival crevicular fluid (GCF) after therapy. This study aimed to evaluate MMP levels in the GCF following treatment of LAP and to correlate these levels with clinical response. Methods GCF samples were collected from 29 African-American individuals diagnosed with LAP. GCF was collected from one diseased site (pocket depth [PD]>4mm, bleeding on probing [BoP] and clinical attachment level [CAL] ≥2mm) and one healthy site (PD≤3mm, no BoP) from each individual at baseline, 3 and 6 months after periodontal treatment, which consisted of full-mouth SRP and systemic antibiotics. The volume of GCF was controlled using a calibrated gingival fluid meter and levels of MMP-1, 2, 3, 8, 9, 12 and 13 were assessed using fluorometric kits. Results MMP-1, 8, 9 12, and 13 levels were reduced significantly up to 6 months, at which point were comparable with healthy sites. Significant correlations were noted between MMP-2, 3, 8, 9, 12 and 13 levels and % of sites with PD>4mm. MMP-3, 12 and 13 levels also correlated with mean pocket depth of affected sites. Conclusion Treatment of LAP with SRP and systemic antibiotics was effective in reducing the local levels specific MMPs in African-American individuals, which correlated positively with some clinical parameters.

    This article critically reviews the evidence for a role of genetic factors in the pathogenesis of aggressive periodontitis and discusses the study approaches commonly used to identify genetic risk factors of this disease. Available data suggest that aggressive periodontitis is caused by mutations in multiple genes, combined with environmental effects. Syndromic periodontal diseases include certain monogenic disorders that express phenotypes showing aggressive forms of periodontitis, and the genetic triggering factors of most of these syndromes have been identified. Other periodontal disease phenotypes seem to occur through different genetic predisposition patterns. Case-control and genome-wide studies have been used to investigate the association with gene polymorphisms. Association studies and the familial aggregation of aggressive periodontitis suggest a significant genetic component in the increased predisposition to this disease. There is evidence to support the contribution of a few major genes or of multiple small-effects genes. In addition, there is evidence of gene-gene and gene-environment interaction effects. Early studies suggested an X-linked mode of transmission of aggressive periodontitis, and subsequent studies support an autosomal mode. Genetic studies have the potential to improve the screening programs of subjects at risk for developing aggressive periodontitis and may enhance treatment outcome through gene therapy.

    The 2 major forms of periodontitis, chronic (CP) and aggressive (AgP), do not display sufficiently distinct histopathological characteristics or microbiological/immunological features. We used molecular profiling to explore biological differences between CP and AgP and subsequently carried out supervised classification using machine-learning algorithms including an internal validation. We used whole-genome gene expression profiles from 310 ‘healthy’ or ‘diseased’ gingival tissue biopsies from 120 systemically healthy non-smokers, 65 with CP and 55 with AgP, each contributing with ≥ 2 ‘diseased’ gingival papillae (n = 241; with bleeding-on-probing, probing depth ≥ 4 mm, and clinical attachment loss ≥ 3 mm), and, when available, a ‘healthy’ papilla (n = 69; no bleeding-on-probing, probing depth ≤ 4 mm, and clinical attachment loss ≤ 4 mm). Our analyses revealed limited differences between the gingival tissue transcriptional profiles of AgP and CP, with genes related to immune responses, apoptosis, and signal transduction overexpressed in AgP, and genes related to epithelial integrity and metabolism overexpressed in CP. Different classifying algorithms discriminated CP from AgP with an area under the curve ranging from 0.63 to 0.99. The small differences in gene expression and the highly variable classifier performance suggest limited dissimilarities between established AgP and CP lesions. Future analyses may facilitate the development of a novel, ‘intrinsic’ classification of periodontitis based on molecular profiling. PMID:24122488

    Dental implants have provided exceptional rehabilitative options for edentulous and partially edentulous patients. However, as more implants come into play, the more the clinicians come across problems where specific considerations must be taken into account to meet expectations. The Toronto Bridge is a treatment modality proposed for restoring several teeth lost in patients with increased crown height (interarch) space. Herein, we applied the Toronto Bridge to rehabilitate a patient with generalized aggressive periodontitis; this article suggests that an implant-supported Toronto Bridge can be a reliable and acceptable treatment modality for patients suffering from tooth loss and vertical bone loss as the result of generalized aggressive periodontal disease.

    Background The comparative treatment response of children and young adults with localized aggressive periodontitis (LAP) affecting primary and permanent dentition is unknown. The objective of this study was to evaluate the influence of non-surgical periodontal therapy with adjunctive systemic antibiotics on the clinical outcome of children/young adults with primary versus permanent dentition affected by LAP. Methods A cohort of 97 African-American participants between the ages of 5–21 (30M; 66F; 22 primary and 75 permanent dentition affected), diagnosed with LAP were included. Patients presented with no significant medical history. All patients underwent periodontal therapy, which consisted of full mouth mechanical debridement at baseline, 3, 6, and 12 month appointments. Additionally, all patients were prescribed a one-week regimen of systemic antibiotics at the initial appointment. Clinical parameters were analyzed, including probing depth (PD), clinical attachment levels (CAL), bleeding on probing (BOP) and percentage of visible plaque. Results Overall, periodontal therapy was found to be effective in improving the clinical outcomes of both primary and permanent dentitions. Although baseline CAL were similar between the groups, the reductions in mean CAL at 3, 6 and 12 months as well as reduction in % Plaque at 3 months were significantly greater in primary dentition as compared to permanent dentition. Conclusions Non-surgical therapy with systemic antibiotics is effective for LAP in both primary and permanent dentitions. A greater reduction in CAL in LAP of primary dentition may suggest that younger children may carry a greater propensity for positive treatment outcomes and healing potential as compared to children/young adults with permanent dentition.

    Aggressive periodontitis (AgP), occurs in a younger age group (≤35 years) and is associated with the rapid destruction of periodontal attachment and supporting bone. Genetic polymorphisms are allelic variants that occur in at least 1% of the population that could potentially alter the function of the proteins that they encode. Interleukins are a group of cytokines that have complex immunological functions including proliferation, migration, growth and differentiation of cells and play a key role in the immunopathogenesis of periodontal disease. The aim of this review was to summarize the findings of studies that reported associations or potential associations of polymorphisms in the interleukin family of cytokines, specifically with AgP.

    Aim To determine microbial profiles that discriminate periodontal health from different forms of periodontal diseases. Methods Subgingival biofilm was obtained from patients with periodontal health (27), gingivitis (11), chronic periodontitis (35) and aggressive periodontitis (24), and analyzed for the presence of >250 species/phylotypes using HOMIM. Microbial differences among groups were examined by Mann-Whitney. Regression analyses were performed to determine microbial risk indicators of disease. Results Putative and potential new periodontal pathogens were more prevalent in subjects with periodontal diseases than periodontal health. Detection of Porphyromonas endodontalis/Porphyromonas spp. (OR 9.5 [1.2–73.1]) and Tannerella forsythia (OR 38.2 [3.2–450.6]), and absence of Neisseria polysaccharea (OR 0.004 [0–0.15]) and Prevotella denticola (OR 0.014 [0–0.49], p<0.05) were risk indicators of periodontal disease. Presence of Aggregatibacter actinomycetemcomitans (OR 29.4 [3.4–176.5]), Cardiobacterium hominis (OR 14.9 [2.3–98.7]), Peptostreptococcaceae sp. (OR 35.9 [2.7–483.9]), P. alactolyticus (OR 31.3 [2.1–477.2]), and absence of Fretibacterium spp. (OR 0.024 [0.002–0.357]), Fusobacterium naviforme/Fusobacterium nucleatum ss vincentii (OR 0.015 [0.001–0.223]), Granulicatella adiacens/Granulicatella elegans (OR 0.013 [0.001–0.233], p<0.05) were associated with aggressive periodontitis. Conclusion There were specific microbial signatures of the subgingival biofilm that were able to distinguish between microbiomes of periodontal health and diseases.

    Background Aggressive periodontitis (AgP) is a severe form of periodontal diseases with rapid destruction of the supporting bone around teeth. The efficacy of PDT in suppressing periodontal pathogens may be crucial in adopting new protocols for the treatment of AgP. Thus, the aim of this systematic review was to investigate the possible role of PDT in the treatment of AgP as an adjunctive therapy or monotherapy. Material and Methods A systematic search of the literature was performed. Additionally, the references from all the selected full-text studies were searched for relevant articles. Two reviewers screened independently titles and abstracts or full text copies. Quality assessment of all the included studies was held. Results Initial screening of electronic databases yielded 418 potentially relevant publications. After screening of the titles and full-text examination, five studies were included in the systematic review. Four publications evaluated the effects of PDT adjunctive to SRP in patients with AgP: two of them compared the clinical outcomes of SRP and PDT with a control group that received therapy with SRP and antibiotics (metronidazole and amoxicillin); two publications included SRP and PDT in the test group, and SRP alone in the control group. In one study, PDT was tested as a monotherapy compared with SRP alone. Conclusions Within the limitations of this review, PDT may exhibit a beneficial role in the therapy of aggressive periodontitis after repeated applications. In the future, more methodologically sound, long-term randomized clinical trials are needed to be conducted. Key words:Photodynamic therapy, periodontitis, systematic review. PMID:26595837

    For decades, Aggregatibacter actinomycetemcomitans has been associated with aggressive forms of periodontitis in adolescents. In the middle of the 1990s, a specific JP2 clone of A. actinomycetemcomitans, belonging to the cluster of serotype b strains of A. actinomycetemcomitans and having a number of other characteristics, was found to be strongly associated with aggressive forms of periodontitis, particularly in North Africa. Although several longitudinal studies still point to the bacterial species, A. actinomycetemcomitans as a risk factor of aggressive periodontitis, it is now also widely accepted that the highly leukotoxic JP2 clone of A. actinomycetemcomitans is implicated in rapidly progressing forms of aggressive periodontitis. The JP2 clone strains are highly prevalent in human populations living in Northern and Western parts of Africa. These strains are also prevalent in geographically widespread populations that have originated from the Northwest Africa. Only sporadic signs of a dissemination of the JP2 clone strains to non-African populations have been found despite Africans living geographically widespread for hundreds of years. It remains an unanswered question if a particular host tropism exists as a possible explanation for the frequent colonization of the Northwest African population with the JP2 clone. Two exotoxins of A. actinomycetemcomitans are known, leukotoxin (LtxA) and cytolethal distending toxin (Cdt). LtxA is able to kill human immune cells, and Cdt can block cell cycle progression in eukaryotic cells and thus induce cell cycle arrest. Whereas the leukotoxin production is enhanced in JP2 clone strains thus increasing the virulence potential of A. actinomycetemcomitans, it has not been possible so far to demonstrate such a role for Cdt. Lines of evidence have led to the understanding of the highly leukotoxic JP2 clone of A. actinomycetemcomitans as an aetiological factor of aggressive periodontitis.

    The aim of the present study was to evaluate the presence of the periodontal pathogens that form the red complex (Tannerella forsythia, Porphyromonas gingivalis and Treponema denticola) and Aggregatibacter actinomycetemcomitans in patients with chronic periodontitis. The sample consisted of 29 patients with a clinical and radiographic diagnosis of chronic periodontitis based on the criteria of the American Academy of Periodontology (3). Samples for microbiological analysis were collected from the four sites of greatest probing depth in each patient, totaling 116 samples. These samples were processed using conventional polymerase chain reaction, which achieved the following positive results: 46.6% for P. gingivalis, 41.4% for T. forsythia, 33.6% for T. denticola and 27.6% for A. actinomycetemcomitans. P. gingivalis and T. forsythia were more prevalent (p < 0.05) in periodontal pockets ≥ 8 mm. The combinations T. forsythia + P. gingivalis (23.2%) and T. forsythia + P. gingivalis + T. denticola (20.0%) were more frequent in sites with a probing depth ≥ 8 mm. Associations with the simultaneous presence of A. actinomycetemcomitans + P. gingivalis, A. actinomycetemcomitans + T. forsythia, P. gingivalis + T. forsythia and T. forsythia + T. denticola were statistically significant (p < 0.05). It was concluded that the red complex pathogens are related to chronic periodontitis, presenting a higher occurrence in deep periodontal pockets. Moreover, the simultaneous presence of these bacteria in deep sites suggests a symbiotic relationship between these virulent species, favoring, in this way, a further progression of periodontal disease.

    DNA microarray analysis is a computer based technology, that a reverse capture, which targets 10 periodontal bacteria (ParoCheck) is available for rapid semi-quantitative determination. The aim of this three-year retrospective study was to display the microarray analysis results for the subgingival biofilm samples taken from patient cases diagnosed with different forms of periodontitis. A total of 84 patients with generalized aggressive periodontitis (GAP,n:29), generalized chronic periodontitis (GCP, n:25), peri-implantitis (PI,n:14), localized aggressive periodontitis (LAP,n:8) and refractory chronic periodontitis (RP,n:8) were consecutively selected from the archives of the Oral Microbiological Diagnostic Laboratory. The subgingival biofilm samples were analyzed by the microarray-based identification of 10 selected species. All the tested species were detected in the samples. The red complex bacteria were the most prevalent with very high levels in all groups. Fusobacterium nucleatum was detected in all samples at high levels. The green and blue complex bacteria were less prevalent compared with red and orange complex, except Aggregatibacter actinomycetemcomitas was detected in all LAP group. Positive correlations were found within all the red complex bacteria and between red and orange complex bacteria especially in GCP and GAP groups. Parocheck enables to monitoring of periodontal pathogens in all forms of periodontal disease and can be alternative to other guiding and reliable microbiologic tests.

    Proteolytic tissue degradation is a typical phenomenon in inflammatory periodontal diseases. HtrA1 (High temperature requirement A 1) has a serine protease activity and is able to degrade fibronectin whose fragments induce the expression and secretion of several matrix metalloproteinases (MMPs). The aim of this study was to investigate for the first time if HtrA1 has a role in gingivitis and in generalized forms of chronic and aggressive periodontitis. Expression of HtrA1 was investigated in 16 clinically healthy gingiva, 16 gingivitis, 14 generalized chronic periodontitis and 10 generalized aggressive periodontitis by immunohistochemistry and real-time PCR. Statistical comparisons were performed by the Kruskall-Wallis test. Significantly higher levels of HtrA1 mRNA and protein expression were observed in pathological respect to healthy tissues. In particular, we detected an increase of plasma cell HtrA1 immunostaining from gingivitis to chronic and aggressive periodontitis, with the higher intensity in aggressive disease. In addition, we observed the presence of HtrA1 in normal and pathological epithelium, with an increased expression, particularly in its superficial layer, associated with increasingly severe forms of periodontal disease. We can affirm that HtrA1 expression in plasma cells could be correlated with the destruction of pathological periodontal tissue, probably due to its ability to trigger the overproduction of MMPs and to increase the inflammatory mediators TNF-α and IL-1β by inhibition of TGF-β. Moreover, epithelial HtrA1 immunostaining suggests a participation of the molecule in the host inflammatory immune responses necessary for the control of periodontal infection.

    Periodontal examination involves evaluation of soft and hard tissue parameters to gauge gingival inflammatory changes and quantify attachment loss. Conventional radiographs are vital components of this process and can be used to assess the presence of calculus and other local factors to establish a diagnosis, prognosis, and periodontal treatment plan. The 2-dimensional nature of these images limits their utility. The advent of high-resolution cone beam computed tomography (CBCT) offers 3-dimensional images that might overcome these limitations. We discuss the use of conventional radiographic techniques as well as CBCT for evaluating, diagnosing, and treatment planning patients presenting for periodontal and/or implant therapy.

    Background: It is well-recognized fact that periodontal diseases are caused by multifactorial etiologies, in which microorganisms play an important role. An essential component of therapy is to eliminate or manage these pathogens. This has been traditionally accomplished through mechanical means by scaling and root planning which is ineffective in some of the aggressive periodontal diseases. These aggressive diseases involve particular groups of microorganisms which are not eliminated by mechanical means; and they require anti-infective therapy, which includes local and systemic antimicrobials. This approach of therapy is of interest to periodontist due to the aforementioned shortcomings of conventional methods. Materials and Methods: A manual and electronic search was made for human studies up to March 2011 that presented clinical and microbiological data for the efficacy of a systemic antibiotics in generalized aggressive periodontitis along with scaling and root planning. A systematic approach was followed by two independent reviewers and included eligibility criteria for study inclusion, quality assessment, and determination of outcome measures, data extraction, data synthesis, and drawing of conclusion. Results: Only three randomized controlled human trials qualified, and they concluded that both scaling and root planing (SRP) mono-therapy and SRP with antibiotics proves beneficial in improving clinical and microbiological parameters in aggressive periodontitis. Better results were seen in SRP with antibiotic groups as compared with SRP alone. Conclusion: Because of the insufficient quantity and heterogenecity of studies, no adequate evidence could be gathered to use the beneficial effects of these antibiotics along with SRP in aggressive periodontitis compared with SRP alone.

    Periodontitis is an inflammatory disease causing loss of tooth-supporting periodontal tissue. Disease susceptibility to the rapidly progressive form of periodontitis, aggressive periodontitis (AgP), appears to be influenced by genetic risk factors. To identify these in a Japanese population, we performed whole exome sequencing of 41 unrelated generalized or localized AgP patients. We found that AgP is putatively associated with single nucleotide polymorphism (SNP) rs536714306 in the G-protein coupled receptor 126 gene, GPR126 [c.3086 G>A (p.Arg1029Gln)]. Since GPR126 activates the cAMP/PKA signaling pathway, we performed cAMP ELISA analysis of cAMP concentrations, and found that rs536714306 impaired the signal transactivation of GPR126. Moreover, transfection of human periodontal ligament (HPDL) cells with wild-type or mutant GPR126 containing rs536714306 showed that wild-type GPR126 significantly increased the mRNA expression of bone sialoprotein, osteopontin, and Runx2 genes, while mutant GPR126 had no effect on the expression of these calcification-related genes. The increase in expression of these genes was through the GPR126-induced increase of bone morphogenic protein-2, inhibitor of DNA binding (ID) 2, and ID4 expression. These data indicate that GPR126 might be important in maintaining the homeostasis of periodontal ligament tissues through regulating the cytodifferentiation of HPDL cells. The GPR126 SNP rs536714306 negatively influences this homeostasis, leading to the development of AgP, suggesting that it is a candidate genetic risk factor for AgP in the Japanese population.

    Periodontal Disease includes a wide variety of infectious entities with various clinical manifestations in the oral cavity and responses to treatment. The determinants of clinical manifestations of periodontal disease include the type of infectious agent, the host immune response and environmental factors. Aggressive periodontitis (AP) is defined as a type of inflammation with specific clinical and laboratory features, which distinguish it from other types of periodontitis, with high incidence rates in a sub-group of individuals. Bacteria have been frequently mentioned as the agent inciting gingival inflammation and tissue destruction that underlies the pathogenesis of periodontitis. However, recent studies, with some controversial results, have suggested that the herpes family of viruses, including CMV and EBV-1 as well as papillomaviruses, HIV, Human T-lymphotropic virus type 1, Torquetenovirus and hepatitis B and C occur with high frequency in active periodontal lesions. There is a lack of information about this disease and the role of herpesviruses in its pathophysiology. This review provides a critical analysis of the scientific evidence linking bacteria and viruses with AP and their potential impact on clinical characteristics, prognosis and therapy. PMID:26980964

    Periodontitis is an inflammatory disease of the gingiva and tissues of the periodontium. It is characterized by pocket formation and destruction of supporting alveolar bone. Periodontal diseases of aggressive nature are not very common in children. They are usually associated with systemic conditions. The present case report is of a 5-year-old male child who reported with rapid attachment loss and bony defects of the gingiva and supporting structures. His family and medical history gave no contribution for the diagnosis. Blood investigations did not reveal any abnormality. The microbial examination of culture revealed the presence of periodontal pathogen Aggregatibacter actinomycetemcomitans. The treatment objective in the present case was to prevent the further progress of the condition, restore esthetic and function in the child which would psychologically benefit the child.

    Background. Transferrin is a negative acute phase protein, which decreases during inflammation and infection. The aim of the present investigation was to evaluate changes in the transferrin serum levels subsequent to non-surgical treatment of chronic periodontal disease. Methods. Twenty patients with chronic periodontitis and 20 systemically healthy subjects without periodontal disease, who had referred to Tabriz Faculty of Dentistry, were selected. Transferrin serum levels and clinical periodontal parameters (pocket depth, clinical attachment level, gingival index, bleeding index and plaque index) were measured at baseline and 3 months after non-surgical periodontal treatment. Data were analyzed with descriptive statistical methods (means ± standard deviations). Independent samples t-test was used to compare transferrin serum levels and clinical variables between the test and control groups. Paired samples t-test was used in the test group for comparisons before and after treatment. Statistical significance was set at P < 0.05. Results. The mean transferrin serum level in patients with chronic periodontitis (213.1 ± 9.2 mg/dL) was significantly less than that in periodontally healthy subjects (307.8 ± 11.7 mg/dL). Three months after periodontal treatment, the transferrin serum level increased significantly (298.3 ± 7.6 mg/dL) and approached the levels in periodontally healthy subjects (P < 0.05). Conclusion. The decrease and increase in transferrin serum levels with periodontal disease and periodontal treatment, respectively, indicated an inverse relationship between transferrin serum levels and chronic periodontitis.

    Periodontitis is considered a consequence of a pathogenic microbial infection at the periodontal site and host susceptibility factors. Periodontal research supports the association of Actinobacillus actinomycetemcomitans, Porphyromonas gingivalis, Prevotella intermedia, and Bacteroides forsythus, and periodontitis; however causality has not been demonstrated. In pursuit of the etiology of periodontitis, we hypothesized that the intracellular bacteria, Chlamydia trachomatis, may play a role. As a first step, a cross-sectional study of dental school clinic patients with established periodontitis were assessed for the presence of C. trachomatis in the oral cavity, and in particular from the lining epithelium of periodontal sites. C. trachomatis was detected using a direct fluorescent monoclonal antibody (DFA) in oral specimens from 7% (6/87) of the patients. Four patients tested positive in specimens from the lining epithelium of diseased periodontal sites, one patient tested positive in healthy periodontal sites, and one patient tested positive in the general mucosal specimen. In conclusion, this study provides preliminary evidence of C. trachomatis in the periodontal sites. Planned studies include the use of a more precise periodontal epithelial cell collection device, the newer nucleic acid amplification techniques to detect C. trachomatis, and additional populations to determine the association of C. trachomatis and periodontitis.

    We report a case of generalized chronic periodontitis and type 2 diabetes mellitus requiring periodontal treatment including regenerative therapy. The patient was a 66-year-old man who presented with the chief complaint of gingival inflammation and mobile teeth in the molar region. He had been being treated for type 2 diabetes mellitus since 1999. His glycated hemoglobin (HbA1c) level was 7.8%. An initial examination revealed sites with a probing depth of ≥7 mm in the molar region, and radiography revealed angular bone defects in this area. Based on a clinical diagnosis of generalized chronic periodontitis, the patient underwent initial periodontal therapy. An improvement was observed in periodontal conditions on reevaluation, and his HbA1c level showed a reduction to 6.9%. Periodontal regenerative therapy with enamel matrix derivative was then performed on #16, 26, and 27. Following another reevaluation, a removable partial denture was fabricated for #47 and the patient placed on supportive periodontal therapy (SPT). To date, periodontal conditions have remained stable and the patient's HbA1c level has increased to 7.5% during SPT. The results show the importance of collaboration between dentist and physician in managing periodontal and diabetic conditions in such patients.

    Background: Myeloperoxidase (MPO) is a lysosomal enzyme found in the azurophilic granules of polymorphonuclear leukocytes and is able to mediate inflammatory tissue destruction in aggressive and chronic periodontitis (CP). Human telomerase is a multi subunit ribonucleoprotein enzyme concerned with telomeric lengthening and homeostasis in man and has been found to be elevated in inflammatory conditions such as rheumatoid arthritis and periodontitis. The aim of this study was to explore in aggressive periodontitis (AP) subjects: (i) The role of MPO-463G/A gene polymorphism and (ii) the level of telomerase expression. These parameters have been compared with the subjects of CP and that of the healthy controls. Materials and Methods: A total of 45 subjects of the age group 20–50 years and free from any known systemic disease were included in the study. They were divided into three groups – Group I-periodontally healthy control (n = 15), Group II-CP (n = 15) and Group III-AP (n = 15). Peripheral blood samples and gingival tissue samples were collected for MPO gene polymorphism and telomerase expression, respectively, for detection by reverse transcriptase polymerase chain reaction. Results: The frequencies of AG and AA genotypes in the MPO gene polymorphism were more common in the AP subjects when compared to the controls. The m-RNA expression of human telomerase reverse transcriptase (hTERT) was undetectable in the gingival tissue of the control group. Its expression in AP subjects was significantly higher than that of CP group (83.61 ± 2.94 in CP and 104.27 ± 6.06 in AP) (P < 0.0001). Conclusions: Our data suggest that MPO-463G/A may be associated with increased risk of AP. The level of tissue hTERT was elevated in AP subjects as compared to CP and healthy control groups.

    The inflammatory mediators, serum elastase and C-reactive protein (CRP), are associated with an increased risk for coronary heart disease. Thus, the aim of this study is to compare systemic inflammatory mediators in periodontally healthy controls (C), patients with untreated aggressive (AgP) and chronic (ChP) periodontitis. C [periodontal pocket probing depth (PPD)  <3.6 or <5 mm without bleeding (BOP), BOP < 10%], ChP (PDD ≥ 3.6 mm and probing attachment loss ≥5 mm at >30% of sites; age >35 years), and AgP (clinically healthy; PDD ≥ 3.6 mm at >30% of sites, bone loss ≥50% at ≥2 teeth; age ≤35 years) were examined clinically, and the body mass index was assessed. Blood was sampled for assessment of serum levels of elastase, CRP, lipopolysaccharide binding protein (LBP), interleukin (IL) 6, 8, and leukocyte counts. Thirty C, 31 ChP, and 29 AgP were analyzed. Elastase, CRP, LBP, and IL-6 levels were elevated in AgP compared to C (p < 0.013), whereas leukocyte counts and IL-8 were similar. Multiple regression analysis identified AgP (p < 0.001) and education level (p < 0.001) to explain 47% of the variation of elastase. AgP (p = 0.003), African origin (p = 0.006), female sex (p = 0.002), and BMI (p < 0.001) explained 39% of the variation of CRP. Serum elastase and CRP are significantly elevated in AgP compared to C. AgP patients exhibit a stronger systemic inflammatory burden than C patients. PMID:22009184

    Objectives: To evaluate bone loss around implants placed in patients with a history of treated chronic periodontitis and who did or did not attend supportive periodontal therapy, after one year in function. Furthermore, the influence of periodontal biotype and level of plaque was also evaluated. Material and Methods: Forty-nine patients participated voluntarily in the study. All subjects had a history of chronic periodontitis, which had been previously treated. After the active treatment, 27 patients attended supportive periodontal therapy (SPT) and the rest did not (No SPT). The O’Leary plaque index and periodontal biotype were recorded for each subject and 246 Astra Tech® OsseospeedTM implants were radiographically analysed (123 placed in SPT patients and 123 in No SPT patients) at the time of loading and one year later, measuring marginal bone loss with the program Dental Studio NX 6.0®. The statistical analysis was performed with Windows SPSS, applying Pearson’s correlation index and the Kruskal-Wallis and U-Mann Whitney non-parametric tests. Results: Six patients were found to have periimplantitis and sixteen mucositis. The survival rate was 99.59% (100% SPT and 99.18% No SPT). Mean bone loss was 0.39 mm (range [-0.71 - 8.05]). Among SPT patients, 95% of the implants had losses less than or equal to the mean (mean bone loss of 0.16 mm) compared to 53.7% for the No SPT group (mean bone loss of 0.62 mm). A statistically significant relationship was demonstrated between bone loss around the implant and the patient’s periodontal biotype and plaque index. Conclusions: The marginal bone loss around implants in patients with treated chronic periodontitis is minimal if they are in a controlled SPT programme and there is individual control of plaque index. Moreover, the presence of a thin periodontal biotype represents a risk factor for additional bone loss. Key words:Peri-implantitis, chronic periodontitis, bacterial plaque, periodontal biotype.

    Objetive: Fibromyalgia (FM) is a chronic pain syndrome with unknown etiology, which affects predominantly women. Mitochondrial alteration could have a role in the pathophysilogical mechanisms of inflammatory conditions as FM and periodontitis. The aim of the present study was assay the relationship between both diseases and mitochondrial dysfunction. Patient and Methods: We study the presence of periodontitis in twelve patients diagnosed of FM and mitochondrial dysfunction described. The diagnosis of FM was established according to ACR criteria and clinical symptoms were evaluated using the Fibromyalgia Impact Questionnaire (FIQ) and Beck Depression Inventory (BDI). Results: Only one patients of twelve included and agreed to participate in the study were diagnosed with periodontitis. Conclusions: Pending studies with larger numbers of patients, we can conclude that mitochondrial dysfunction in FM is a itself event not related with periodontitis. Periodontitis could be considered a exclusion criterion in all studies about mitochondrial dysfunction in patients. Key words:Peridontitis, fibromyalgia, mitocondrial dysfunction, oxidative stress.

    Background Periodontitis has been regarded as a potential risk factor for rheumatoid arthritis (RA). A systematic review is made to determine whether nonsurgical periodontal treatment in patients with RA offers benefits in terms of the clinical activity and inflammatory markers of the disease. Material and Methods A search was made of the Medline-PubMed, Cochrane, Embase and Scopus databases to identify studies on the relationship between the two disease processes, and especially on the effects of nonsurgical treatment in patients of this kind. The search was based on the following keywords: rheumatoid arthritis AND periodontitis (MeSH), rheumatoid arthritis AND periodontal treatment. Results Eight articles on the nonsurgical treatment of patients with periodontitis and RA were finally included in the study. All of them evaluated clinical (DAS28) and laboratory test activity (ESR, CRP, IL-6, TNFα) before and after treatment. A clear decrease in DAS28 score and ESR was recorded, while other parameters such as CRP, IL-6 and TNFα showed a non significant tendency to decrease as a result of treatment. Conclusions Nonsurgical treatment improved the periodontal condition of patients with periodontitis and RA, with beneficial effects upon the clinical and laboratory test parameters (DAS28 and ESR), while other inflammatory markers showed a marked tendency to decrease. However, all the studies included in the review involved small samples sizes and follow-up periods of no more than 6 months. Larger and particularly longitudinal studies are therefore needed to more firmly establish possible significant relations between the two disease processes.

    Background and Objectives: Nitric oxide (NO) is a ubiquitous intercellular messenger molecule with important cardiovascular, neurological, and immune functions. In addition, it has been postulated that the pharmacological inhibition of NO or its actions may be therapeutically valuable in the disease management. The levels of nitric oxide may provide clues about the severity and the state of the underlying disease process. It could be an inflammatory biomarker that may enable clinicians to direct the environmentally based prevention or treatment programmes and to establish whether NO plays a role in the pathogenesis of periodontitis or not. Hence, the aim of the present study was to evaluate the salivary and the serum levels of NO in generalized chronic and aggressive periodontitis. The Study Design: Unstimulated whole saliva and serum samples were collected from a total of 60 subjects who were in the age group of 18-45 years, who participated in this study. They were divided into three equal groups with 20 subjects in each group; group A (healthy controls), group B (chronic periodontitis) and group C (aggressive periodontitis). The clinical parameters were assessed, based on the oral hygiene index simplified (OHI-S), the gingival index (GI), the probing pocket depth and the clinical attachment loss (CAL). A biochemical analysis was performed to evaluate and compare the salivary and the serum nitric oxide levels of the above groups. Statistical Analysis and Results: The statistical comparisons were done under the Griess Reaction. There were statistically significant salivary and serum levels of NO in the groups of periodontitis (group B and C) as compared to those in the healthy controls (group A). A significant positive correlation was found between the values of the salivary and the serum NO levels in chronic and aggressive periodontitis. Conclusion: Nitric oxide is a potent modulator of the inflammatory disease processes and under pathological conditions, NO has

    Several studies have shown a role for the involvement of interleukin (IL)-1 gene cluster polymorphisms in the risk of periodontal diseases. In the present study, we tested polymorphisms, derived from genes of the IL-1 cluster, for association with generalized aggressive periodontitis (GAP) through both allelic association and by constructing a linkage disequilibrium (LD) map of the 2q13-14 disease candidate region. The IL-1RN (VNTR) genotype distribution observed was significantly different in GAP and control subjects (P=0.019). We also observed some evidence for an association between GAP and the IL-1B(+3953) polymorphism (P=0.039). The pattern of association in the region, represented as an LD map, identifies a recombination hot area between the IL-1B(+3953) and IL-1B(-511) polymorphisms. Multilocus modelling of association with disease gives a location for the peak association at the IL-1B(+3953) marker, although support for the peak is not significant. Haplotype analysis identifies a IL-1B(+3953)-IL-1B(-511) haplotype as having the lowest P-value in the region. Recognition of the presence of a recombination hot area between the IL-1B(+3953) and IL-1B(-511) polymorphisms will have an important bearing on future efforts to develop higher resolution SNP analysis in this region for both this and other diseases for which this cluster is implicated.

    Objectives: The purpose of this study was to analyze how anti-infectious periodontal treatment affects C reactive protein (CRP) values in patients with type 1 diabetes, and correlate baseline CRP levels with periodontal disease severity. Study Design: A cohort of fifty three subjects with type 1 diabetes and moderate to severe periodontitis were recruited. Periodontal parameters were measured, and blood samples were obtained to evaluate high-sensitivity C-reactive protein (hs-CRP). Group 1 was treated with scaling, root planning, and systemic administration of doxycycline. Group 2 received only scaling and root planning. Results: Hs-CRP was reduced after periodontal treatment in group 1 (-0.22 mg/l) and 2 (-0.21 mg/l ) but this reduction was not statistically significant, even in the patients with the best response to periodontal treatment. However, significant correlation appeared between hs-CRP and mean probing pocket depth (PPD) (p=0, 01) and mean clinical attachment level (CAL) (p=0,03). Conclusions: Non-surgical periodontal treatment couldn’t reduce hs-CRP values, however, it was found an association between advanced periodontitis and elevated blood hs-CRP levels in patients with type 1 diabetes. It can be speculated that periodontal disease increases production of pro-inflammatory mediators in patients with type 1 diabetes, but other producing sources of these pro-inflammatory substances may exist.

    Periodontal disease is considered a risk factor in dental implant treatment. The purpose of this study was to investigate the periodontal conditions in patients requesting dental implant therapy. A total of 169 patients visiting Department of Oral and Maxillo-Facial Implantology at Tokyo Dental College Chiba Hospital were targeted. The following intraoral parameters were measured in each patient: Community Periodontal Index (CPI) score, probing pocket depth (PPD), clinical attachment level (CAL) and bleeding on probing (BOP). Prevalence of patients with periodontal pockets was high: 38% and 28% of patients had a CPI score of code 3 and 4, respectively. Prevalence of teeth with one or more sites with PPD≥4mm was 27%. Moreover, clinical signs suggestive of periodontitis (PPD, CAL≥4mm) were found in 10-15% of tooth sites. Prevalence rates at sites with severe periodontal breakdown (PPD, CAL≥7mm) were 2-5%. These results further emphasize the importance of thorough periodontal assessment in patients prior to dental implant treatment.

    Efficiency of some drugs in the treatment of periodontitis in combination with corrective treatment of thyroid function was evaluated in 70 patients with hypo- and hyperthyrosis with different initial level of nonspecific resistance. The therapeutic complex including drugs commonly used in the treatment of periodontitis and irrigation of the periodontium with lithium chloride and chlorohexidine solutions was highly effective in patients with thyroid dysfunction and relatively favorable status of nonspecific resistance of the organism. In patients with hypo- and hyperthyrosis with poor nonspecific resistance the best effect in the treatment of periodontitis was attained with potassium orotate as an immunomodulator and lithium chloride.

    Periodontitis is a common disease that is considered to be a manifestation of the distortion of the ratio between the normal and conditionally pathogenic microflora of periodontal pockets. In this study, the ratio between the six most important periodontal pathogens and the total microflora of the periodontal pocket in healthy individuals and patients with varying severity of periodontitis was ascertained by quantitative real-time PCR. It was ascertained that the relative content ofPorphyromonas gingivalis,Prevotella intermedia, andTannerella forsythensis(Bacteroides forsythus) persistently develops in the total microflora of the periodontal pocket upon progressing periodontitis; this value is higher than that in the control group by more than two orders of magnitude upon a severe degree of chronic generalized periodontitis.

    Background: The present cross-sectional survey study was conducted to assess whether the transtheoretical model for oral hygiene behavior was interrelated in theoretically consistent directions in chronic periodontitis patients and its applicability to assess the compliance of the chronic periodontitis patients to the treatment suggested. Materials and Methods: A total of 150 chronic periodontitis patients were selected for the proposed study. The selected patients were given four questionnaires that were constructed based on transtheoretical model (TTM), and the patients were divided subsequently into five different groups (precontemplation, contemplation, preparation, action, and maintenance groups) based on their answers to the questionnaires. Then, each patient was given four appointments for their periodontal treatment spaced with a time gap of 10 days. The patients visit for each appointments scheduled to them was documented. The results obtained were assessed using TTM. Results: Higher mean pro scores of decisional balance, self-efficacy, and process of change scores was recorded in maintenance group followed by action group, preparation group, contemplation group, and precontemplation group, respectively, whereas higher mean cons score was recorded in precontemplation group followed by contemplation group, preparation group, action group, and maintenance group, respectively. The difference scores of TTM constructs were statistically highly significant between all the five groups. Furthermore, the number of appointment attended in were significantly more than maintenance group followed by action group, preparation group, contemplation group, and precontemplation group. Conclusion: Within the limitations of this study, it can be concluded that transtheoretical model can be successfully applied to chronic periodontitis patients to assess their compliance to the suggested periodontal treatment.

    Multiple studies had focused on the association between interleukin-1 (IL-1) rs1143634 polymorphism and aggressive periodontitis (AgP) susceptibility, but the results remained inconclusive. Therefore, this meta-analysis was conducted to explore its role in the development of AgP. PubMed and Embase databases were searched up to April 15, 2014. After study selection and data extraction form eligible studies, meta-analysis was performed. Odds ratios (ORs) and 95% confidence intervals (CIs) were used to evaluate the association. All the analysis was performed using Comprehensive Meta-Analysis software. Finally a total of 25 case-control studies were included. The pooled results showed non-association between AgP susceptibility and IL-1 rs1143634 polymorphism [for T vs. C: OR = 0.99, 95% CI = 0.79-1.23; for TT vs. CC: OR = 1.14, 95% CI = 0.78-1.66; for CT vs. CC: OR = 0.97, 95% CI = 0.70-1.36; for (CT + TT) vs. CC: OR = 1.02, 95% CI = 0.76-1.37; for TT vs. (CT + CC): OR = 1.22, 95% CI = 0.85-1.75]. Subgroup analyses remain did not find any association. No publication bias was detected. Hence, our meta-analysis showed that IL-1β rs1143634 polymorphism is not linked to AgP susceptibility, regardless of ethnicity. PMID:25932167

    Because of adverse effects of uremia in the innate and adaptive immune systems, we hypothesized that chronic kidney disease (CKD) patients would have higher prevalence of moderate periodontitis compared with individuals without CKD. We examined this hypothesis using the NHANES III dataset, including 12,081 adults stratified by Race-Ethnicity. We followed the American Academy of Periodontology/Centers for Disease Control and Prevention definition for moderate periodontitis. Estimated glomerular filtration rate (GFR) was calculated based on calibrated serum creatinine levels according to the Modification of Diet in Renal Disease Study formula. Analyses incorporated NHANES sampling weights. Overall, 14.6% of individuals with CKD were classified as having moderate periodontitis, compared with 8.7% in the non-CKD group (p = 0.001). A significant dose-response association (p = 0.001) was observed between prevalence of moderate periodontitis and CKD stages among non-Hispanic Blacks and Mexican-Americans, but not so for non-Hispanic Whites. Prevalence of periodontitis among participants with CKD was substantially higher among non-Hispanic Blacks (38.9%) and Mexican-Americans (37.3%) compared with non-Hispanic Whites (12.9%). Multivariate logistic regression models showed that Mexican-Americans and non-Hispanic Blacks with CKD were approximately 30% to 60% more likely to have moderate periodontitis compared with those without CKD, after adjustment for diabetes status and other potential confounders.

    Background and aims Recent epidemiological studies have shown that individuals with periodontitis have a significantly higher risk of developing coronary heart disease, which might be attributed to the complex microbiota in the dental plaque. Periodontopathogens have been reported as risk factors for cardiovascular disease. This study evaluated association of chronic periodontitis and periodontopathogens with CRP in systemically healthy Serbian adults. Materials and methods Serum C-reactive protein levels were measured in 24 patients with moderate periodontitis, 26 patients with severe periodontitis, and 25 periodontally healthy subjects. Periodontal health indicators included gingival bleeding on probing and periodontal disease status. Patients with moderate periodontitis had low attachment loss and pocket depths of <4 mm. Patients with severe periodontitis had high AL and pocket depth of >5 mm. The control group with healthy gingiva had gingival sulcus of <2 mm and no attachment loss. Presence of periodontopathogens in subgingival plaque samples was analyzed by polymerase chain reaction. Results The periodontal parameters and CRP levels were significantly higher in the patients with periodontitis. Patients who had both severe and moderate periodontitis had higher mean CRP levels. The percentage of subjects with elevated CRP leves of >5 mol/L was greater in the higher clinical AL group compared to the group with less attachment loss. Presence of periodontopathogens was also associated with elevated CRP levels and poor periodontal status. Conclusion PD and subgingival periodontopathogens are associated with increased CRP levels. These findings suggest that periodontal infection may contribute to systemic inflammatory burden in otherwise healthy individuals. PMID:23019501

    HIV/Aids patients present a change of microbiota associated with host immunodeficiency. Photodynamic therapy (PDT) showed as a promising and viable alternative in reducing microbiota. Present study evaluate effectiveness of photodynamic therapy in periodontal disease of AIDS patients with highly activity antiretroviral therapy (HAART) failure, measuring the clinical periodontal parameters and periodontal microbiota. Twelve patients with HARRT resistance (R group) divided into two groups (control and PDT) and 12 patients with no HAART resistance (NR group) divided into two groups (control and PDT). The results show the difference in baseline of CD4 cells count, NR group 640.0 +/- 176.2 cells/mm3 R group and 333.3 +/- 205.8 cells / mm3 (p<0.05), and in 8.3% detectable viral load in NR group and 75% detectable (p <0.001) in R group. As clinical periodontal parameters (PD and CAL), PDT was more effective than the control group only in the NR group (p <0.05%), moreover, there was no difference in the evaluation of clinical periodontal parameters between the both R groups (p>0.05%). Microbiological evaluation in R group presents a general reduction in the Aa at 3 and 6 months. Furthermore, demonstrated a reduction of Pg in all groups at 6 months and in R group at 3 months. The impact assessment of photodynamic therapy in patients with different levels of immunosuppression determined that the combination of mechanical periodontal treatment with photodynamic therapy in patients with HAART failure did not cause additional benefits. Therefore, PDT in this study could not been indicated in HAART resistance patients.

    Virulent bacteria could cause gingival fibroblasts apoptosis through lipopolysaccharide release during generalized aggressive periodontitis (GAgP) development and evolution. We showed that treatment with lipopolysaccharide (LPS, 1 μg/mL) for 30 days induced the decrease in the number of cultured rat gingival fibroblasts as compared to control group, which received no treatment. GAgP is considered to have also a genetic etiology, so the aim of our study was to evaluate if some polymorphisms of tumor necrosis factor-alpha (TNFA) and interleukin 1A (IL-1A) genes are associated with GAgP in a sample of Romanian population. We selected a group of 32 subjects (22 cases and 10 controls) for studying the TNFA (-857) polymorphism and 97 subjects (66 cases and 31 controls) for IL-1A (-889) polymorphism. The single nucleotide polymorphisms were genotyped by real-time polymerase chain reaction for all subjects. The genotype and allelic distribution tended to be equally between the cases and the controls group. Similar results were obtained for the dominant and recessive model. The difference between the two groups did not reach statistic significance for neither of the two studied polymorphisms [p=0.76 for TNFA (-857) and p=0.84 for IL-1A (-889)]. The data suggest that TNFA (-857) C/T and IL-1A (-889) C/T polymorphisms are not associated with susceptibility to GAgP in this Romanian population, potentially because of the small sample size. This is the first such study for Romanian northeastern population. PMID:26193214

    Abstract Epidemiologic studies have reported increased incidence, prevalence and acuity of periodontitis in adults with diabetes and some have also suggested that treating periodontal disease may improve glycemic control in diabetic patients. This meta-analysis was conducted to evaluate the effects of different periodontal therapies on metabolic control in patients with type 2 diabetes mellitus (T2DM) and periodontal disease. We searched the Medline, EMBASE and Cochrane Library (Central) databases up to January 2014 for relevant studies pertaining to periodontal treatments and glycemic control in adults with T2DM. The search terms were periodontal treatment/periodontal therapy, diabetes/diabetes mellitus, periodontitis/periodontal and glycemic control. The primary outcome measure taken from the included studies was glycated hemoglobin (HbA1c). We compared differences in patients’ pre- and post-intervention HbA1c results between a treatment group receiving scaling and root planing (SRP) combined with administration of oral doxycycline (n = 71) and controls receiving SRP alone or SRP plus placebo (n = 72). Meta-analysis was performed using Comprehensive Meta Analysis software. Nineteen randomized controlled trials (RCTs) were identified. Four trials involving a total of 143 patients with T2DM and periodontal disease were determined to be eligible for analysis. Data of 1 study were not retained for meta-analysis because HbA1c results were recorded as median with IQR. Meta-analysis of the included 3 studies revealed no significant differences in HbA1c results between the periodontal treatment group (n = 71) and control group (n = 72) (HbA1c SMD = −0.238, 95% CI = −0.616 to 0.140; P = 0.217). Systemic doxycycline added to SRP does not significantly improve metabolic control in patients with T2DM and chronic periodontitis. Current evidence is insufficient to support a significant association between periodontal therapy and metabolic

    This study investigated the prevalence of Actinomyces spp. in shallow, deep and very deep pockets of patients with chronic periodontitis compared to healthy controls and correlated the results with clinical status. Twenty patients with chronic periodontitis and 15 healthy subjects were enrolled in this study. Clinical indices were recorded in a six-point measurement per tooth. From each patient samples of supra and subgingival plaque were taken separately from teeth with shallow, deep and very deep pockets. Samples of supragingival plaque and sulcular microflora were collected from the healthy subjects. All the samples were cultivated on different media at 37̊C in an anaerobic atmosphere for 7 days. All the suspect colonies were identified using a rapid ID 32 A system (bioMèrieux) and MALDI-TOF-MS analysis using an Autoflex II Instrument (Bruker Daltonics) together with in house developed identification software and a reference spectra database. A total of 977 strains were identified as Actinomyces. Actinomyces naeslundii/oris/johnsonii (430 isolates) was the most prevalent species and was found in all patients and in almost all of the healthy subjects. Significant differences (p=0.003) between the groups were found for Actinomyces odontolyticus/meyeri and Actinomyces israelii which were associated with periodontitis patients. Actinomyces dentalis was found in higher percentage (p=0.015) in the periodontitis group. Actinomyces gerencseriae and Actinomyces massiliensis were significantly more often found supragingivally than subgingivally (p=0.004, p=0.022, respectively) in the periodontitis group. Whether some Actinomyces species, definitely important plaque formers, are actively involved in the pathogenicity of chronic periodontitis needs further investigation.

    Statement of the Problem Trichomonas tenax and Entamoeba gingivalis are commensal protozoa which inhabit the human oral cavity. These parasites are found in patients with poor oral hygiene and might be a reason for progressive periodontal diseases. Purpose The aim of this study was to evaluate the effect of nonsurgical periodontal treatment on the frequency of these protozoa in saliva and plaque samples. Materials and Method In this clinical trial, samples of saliva and dental plaque were collected from 46 patients with moderate to severe chronic periodontitis before and after periodontal therapy. The samples were assessed for the frequency of parasites. Results The frequency of Entamoeba gingivalis was reduced in saliva (p= 0.007) and plaque (p= 0.027) three weeks after the treatment. Likewise, the frequency of Trichomonas tenax reduced in saliva (p= 0.030); however, the decrease was not significant in plaque (p= 0.913). Trichomonas tenax frequency in dental plaque directly related to the severity of periodontitis (r= 0.565, p≤ 0.000). In contrast, the number of Entamoeba gingivalis in both saliva (r= -0.405, p≤ 0.005) and plaque (r= -0.304, p= 0.040) was inversely related with the severity of the periodontal disease. Conclusion Nonsurgical periodontal treatment could reduce the number of Trichomonas Tenax and Entamoeba gingivalis in the oral environment of patients with chronic periodontitis. PMID:27602391

    Statement of the Problem Trichomonas tenax and Entamoeba gingivalis are commensal protozoa which inhabit the human oral cavity. These parasites are found in patients with poor oral hygiene and might be a reason for progressive periodontal diseases. Purpose The aim of this study was to evaluate the effect of nonsurgical periodontal treatment on the frequency of these protozoa in saliva and plaque samples. Materials and Method In this clinical trial, samples of saliva and dental plaque were collected from 46 patients with moderate to severe chronic periodontitis before and after periodontal therapy. The samples were assessed for the frequency of parasites. Results The frequency of Entamoeba gingivalis was reduced in saliva (p= 0.007) and plaque (p= 0.027) three weeks after the treatment. Likewise, the frequency of Trichomonas tenax reduced in saliva (p= 0.030); however, the decrease was not significant in plaque (p= 0.913). Trichomonas tenax frequency in dental plaque directly related to the severity of periodontitis (r= 0.565, p≤ 0.000). In contrast, the number of Entamoeba gingivalis in both saliva (r= -0.405, p≤ 0.005) and plaque (r= -0.304, p= 0.040) was inversely related with the severity of the periodontal disease. Conclusion Nonsurgical periodontal treatment could reduce the number of Trichomonas Tenax and Entamoeba gingivalis in the oral environment of patients with chronic periodontitis.

    Aggressive periodontitis is characterized by non-contributory medical history, rapid attachment loss and bone destruction and familial aggregation of cases. Aggressive periodontitis (both localized and generalized) is usually diagnosed in a young population. This is frequently the age that an orthodontic care is provided to this population. The aim of the present paper is to draw guidelines for periodontal evaluation and monitoring prior to and during active orthodontic treatment. Strict adherence to these guidelines as a routine protocol for periodontal examination prior, during and following orthodontic treatment may dramatically decrease the severity and improve the prognosis of patients with aggressive periodontitis in orthodontic clinics.

    We studied xerostomy and its correlation with periodontal and dental cavity diseases in HIV patients, through measurement of salivary flow and through variables such as saliva buffer capacity, salivary pH, periodontal index, MDF index, dental carie risk and risk of periodontal disease. One hundred patients were analyzed. They were distributed into two groups: Group I (test) - 50 patients evidently HIV+, from whom information was collected and analyzed regarding age, gender, skin color, habits, general and oral diseases, levels of T-CD4 lymphocytes, viral load and highly active antiretroviral therapy (HAART); and Group II - (control) 50 HIV- patients, from whom information was collected and analyzed regarding age, gender, skin color, habits, general and oral diseases. In both groups, measurement of salivary flow, pH and buffer capacity was made. Group I presented high MDF, bacteria plaque and bleeding, with a greater susceptibility to the risks of oral cavities and periodontal disease. The salivary flow and the buffering capacity of the saliva were low, indicating a high level of xerostomy. Two important modifying factors influence these pathologies in an incisive way: one is immunossuppression and the other is HAART therapy. The control exhibited results that are closer to normality; it had better oral-health conditions.

    Calcium antagonists are widely used in treating acute and chronic coronary insufficiency disorders. A major side effect of long-term treatment is gingival hyperplasia. In the present study, 70 patients taking nifedipine for at least six months and 70 controls similar in age, gender, approximal hygiene and systemic disease with at least 6 anterior teeth in upper and lower arches were examined. Their periodontal conditions were determined by modified Sulcus-Bleeding-Index (mSBI), modified Approximal-Plaque-Index (mAPI), Community Periodontal Index of Treatment Needs (CPITN), a hyperplasia index quantifying the extent of gingival overgrowth, probing depths, clinical attachment loss and the modified Phenytoin-Gingival-Inflammation-Index (mPGI). A mild to moderate gingival hyperplasia was diagnosed in 21 of 70 patients resulting in a prevalence of 30% compared to 8.5% in controls. The hyperplastic changes were situated mainly in the anterior region of the dentition. Significant differences between both groups could be found comparing the severity of the gingival hyperplasia, the CPITN, mSBI, probing depths and the part of mPGI evaluating colour and turgor of the gingiva (p < 0.05). The severity of gingival overgrowth was strongly correlated with the inflammatory gingival changes, probing depths, the periodontal treatment need and the approximal hygiene of the patients. No statistically significant correlation could be found between the severity of gingival hyperplasia and the age and gender of the patient, or the dose or duration of nifedipine therapy. Gingival changes seemed to be more pronounced in patients with cardiovascular disorders than in patients under hemodialysis. The high incidence of gingival hyperplasia in patients receiving nifedipine on a long-term basis emphasises the role of the dentist and general practitioner in the early detection and prophylaxis of gingival changes and requires a thorough information to the patient concerning periodontal side

    Background and aims. Visfatin, mainly secreted by visceral adipose tissue, especially by macrophages, plays an important role in regulating the defense and immune functions, and functions as a growth factor, a cytokine, an enzyme and more importantly as a proinflammatory mediator. The aim of the present study was to evaluate the effect of non-surgical periodontal treatment on serum and salivary levels of visfatin in patients with generalized moderate-to-severe chronic periodontitis. Materials and methods. Eighteen patients with generalized moderate-to-severe chronic periodontitis were selected based on periodontal parameters of gingival index (GI), probing pocket depth (PPD), clinical attachment level (CAL) and radiographic parameters. Serum and salivary samples were collected at baseline and one month following non-surgical periodontal therapy (scaling and root planing ([SRP]). Visfatin levels were measured using an ELISA kit. Data were analyzed by SPSS 15, using paired t-test and Pearson's correlation coefficient. Results. Mean salivary and serum levels of visfatin significantly decreased after non-surgical periodontal treatment (P<0.05). Changes in salivary visfatin levels were more prominent. Conclusion. According to the findings of this study it seems that there is a direct relationship between periodontal tissue inflammation and disease activity with salivary and serum visfatin levels.

    Introduction: Periodontal disease is an inflammatory condition affecting tooth supporting structures in which dysregulated immune response and oxidative stress mediate tissue destruction. Melatonin, the pineal gland hormone is a regulator of circadian rhythm, an antioxidant and an immunomodulator. Previous studies have shown lowered melatonin levels in saliva, plasma and gingival crevicular fluid (GCF) of patients with periodontal disease. Till date no study has assessed the melatonin levels in gingival tissues. Materials and Methods: Five healthy individuals and 15 chronic periodontitis patients were recruited for this pilot study. 5ml of whole saliva, 2 ml peripheral blood and gingival tissue samples were obtained from each individual at 8.00 am in fasting state. Melatonin assay was performed with a commercially available ELISA kit. Statistical analysis was done to assess the difference in mean melatonin levels among the groups. Results: No statistically significant difference was found in mean melatonin levels between healthy individuals and chronic periodontitis patients in saliva (p=.266) and plasma (p=.933) samples, whereas in gingival tissue samples (p=.015), the melatonin levels were significantly lowered in chronic periodontitis patients compared to healthy individuals. Conclusion: This study demonstrates the presence of melatonin in gingival tissue. Furthermore, melatonin levels are lowered in gingival tissues of chronic periodontitis patients. PMID:25954699

    Exuberant gingival inflammation accompanied by periodontitis is a rare finding in a very young child and may indicate a defect in the host response. Affected children should be referred to appropriate specialists to establish a definitive diagnosis. A 5-year-old girl presented with persistent gingival inflammation and periodontal destruction. Immunological investigations identified specific polysaccharide antibody deficiency which, when treated, resulted in a significant improvement in the gingival condition. This case illustrates the need for integrated management by a wide range of dental and medical specialists. Antibody deficiency is rare but, if not identified and treated effectively, can be associated with chronic ill health and decreased life expectancy. CPD/Clinical Relevance: This article describes a rare case of gingival inflammation accompanied by periodontitis in a very young child secondary to an underlying host antibody deficiency and details the investigation, management and clinical outcomes.

    The aim of the present study was to evaluate the mean bacterial load of some periodontal pathogenic bacteria in Italian patients affected by chronic periodontitis. The sample consisted of 1,762 patients with a clinical diagnosis of chronic periodontitis based on the criteria of the American Academy of Periodontology sampled in the period 2013-2015; 1,323 patients were from Northern Italy, 317 from Central Italy and 122 from Southern Italy. Samples for microbiological analysis were collected from the four sites of the greatest probing depth in each patient and then processed by quantitative polymerase chain reaction. Periodontal pathogens have the following percentage respect to total bacteria load: Aggregatibacter actinomycetemcomitans 0.1%, Campylobacter rectus 2%, Fusobacterium nucleatum 8%, Porphyromonas gingivalis 6%, Treponema denticola 2% and Tannerella forsythia 1.5%. There are significant differences in bacterial load among the different geographical areas both for the total bacterial and for the single species. The results of our study in this Italian population showed that a different geographic distribution exists among periodontal pathogens. We hypothesize that these differences in bacterial load could be related to genetic and environmental factors. Additional studies are necessary to confirm these data and to get more insight on additional factors, which may play a role in periodontal pathogens in different geographic areas. PMID:27469562

    Although cleft lip and palate patients are usually treated by a multidisciplinary team involving physicians and dentists, their periodontal condition may be over-looked. Crowded or malpositioned teeth, hypertrophic gingiva, orthodontic appliances, and prosthetic replacements can impede proper plaque removal and thus perpetuate periodontal disease. It is important to incorporate periodontal treatment into the comprehensive treatment as early as possible. This case report discusses the periodontal surgical procedures involved in eliminating a residual ridge defect and the fitting of the final prosthetic reconstruction. Also, the importance of the identification and management of periodontal conditions characteristic of cleft lip and palate patients before and after surgical, orthodontic, and prosthetic rehabilitation will be emphasized.

    Verbally aggressive behaviour on psychiatric wards is more common than physical violence and can have distressing consequences for the staff and patients who are subjected to it. Previous research has tended to examine incidents of verbal aggression in little detail, instead combining different types of aggressive behaviour into a single measure. This study recruited 522 adult psychiatric inpatients from 84 acute wards. Data were collected from nursing and medical records for the first 2 weeks of admission. Incidents of verbal aggression were categorized and associations with patient characteristics examined. There were 1398 incidents of verbal aggression in total, reported for half the sample. Types of verbal aggression were, in order of prevalence: abusive language, shouting, threats, expressions of anger and racist comments. There were also a large number of entries in the notes which did not specify the form of verbal aggression. Staff members were the most frequent target of aggression. A history of violence and previous drug use were consistently associated with verbal aggression. However, there were also some notable differences in patient variables associated with specific types of verbal aggression. Future studies should consider using multidimensional measures of verbal aggression.

    Background and aims. Melatonin is a circulating hormone that is mainly released from the pineal gland. It possesses antioxidant, free-radical scavenging, and immune-enhancing properties. A growing number of studies reveal a complex role for melatonin in influencing various diseases, including diabetes and periodontal diseases. The aim of this study was to examine the possible links between salivary melatonin levels and type II diabetes and periodontal diseases. Materials and methods. A total of 30 type II diabetic patients, 30 patients with periodontal diseases, 30 type II diabetic patients with periodontal disease and 30 age- and BMI-matched controls were studied. The periodontal status was evaluated by the Community Periodontal Index (CPI). Salivary melatonin levels were determined by a commercial enzyme-linked immunosorbent assay (ELISA) kit. Results. The mean of salivary melatonin level was significantly lower in patients with either periodontitis or diabetes compared to healthy subjects (P < 0.05). Salivary melatonin concentration decreased in type II diabetic patients and periodontitis patients, and then decreased reaching the lowest levels in type II diabetic patients with periodontal disease. Conclusion. Based on the results of this study, it can probably be concluded that salivary level of melatonin has an important role in the pathogenesis of diabetes and periodontal diseases. It is also worth noting that this factor could probably be used as a pivotal biological marker in the diagnosis and possible treatment of these diseases, although further research is required to validate this hypothesis.

    2 334 patients from 29 dental practices took part in a written survey on their experiences with dental treatment in general as well as treatment of periodontal disease (response rate 80.8%). 72.6% of all participating patients fully agreed that they could recommend their dentist to their friends. 63.6% of patients undergoing treatment of periodontitis (N=328) rated this treatment as "excellent". However, for important aspects (prevention, patient information, treatment) potentials for improvement became obvious. 43.7% of patients treated for periodontitis were not completely satisfied with information on how this disease develops; 40.7% saw potentials for better information on preventive care (dental-hygiene, nutrition). An even higher percentage of patients actually not treated for periodontitis was interested in more information on prevention (51.4%). The results of the survey show that dentists should offer information and exercise on how to prevent periodontal desease more actively. There is a lack of research on the present state of affairs and potentials for improvement concerning treatment and prevention of periodontitis including the patients' perspective. PMID:26086539

    Over the past 20 or so years, a number of studies have examined patient aggression toward healthcare professionals. While the majority of these studies has focused on healthcare professionals in the fields of emergency medicine, psychiatry, and primary care, available data extends beyond these three specialties. Studies have been done in the United States, other English-speaking countries, and elsewhere— all reporting surprisingly high rates of patient aggression. Results indicate that patient aggression toward healthcare professionals is common and worldwide. In addition, one study examined aggressive patient behaviors as reported by the patients themselves, and their self-report data reinforce the mainstream data. While these data do not enable us to determine if patient aggression is genuinely on the increase, we can safely say that these behaviors are rampant. PMID:25621187

    We describe the diagnosis and treatment of a class II division 1 malocclusion complicated by severe periodontal disease, tooth loss, dentoalveolar protrusion associated with tipping and extrusion of the maxillary incisors, and a traumatic occlusion. Treatment involved the use of a modified palatal arch to intrude and retract the maxillary incisors and high-pull headgear to enhance anchorage and correct the Class II relationship. After active treatment for 19 months, a good anterior occlusion was achieved, with 17° of lingual retroclination and 3 mm of intrusion at the apex of the maxillary incisors. An acceptable occlusion and periodontal status was maintained over a retention period of 2 years. With the patient's cooperation, a successful outcome was achieved with this approach.

    Multiple studies have shown that diabetes mellitus is an established risk factor for periodontitis. Recently mesenchymal stem cells derived from periodontal ligament (PDLSCs) have been utilized to reconstruct tissues destroyed by chronic inflammation. However, impact of periodontitis with diabetes mellitus on PDLSCs and mechanisms mediating effects of complex microenvironments remain poorly understood. In this study, we found multiple differentiation potential of PDLSCs from chronic periodontitis with diabetes mellitus donors (D-PDLSCs) was damaged significantly. Inhibition of NF-κB signaling could rescue osteogenic potential of PDLSCs from simple chronic periodontitis patients (P-PDLSCs), whereas did not promote D-PDLSCs osteogenesis. In addition, we found expression of DKK1 in D-PDLSCs did not respond to osteogenic signal and decreased osteogenic potential of D-PDLSCs treated with DKK1 could be reversed. To further elucidate different character between P-PDLSCs and D-PDLSCs, we treated PDLSCs with TNF-α and advanced glycation end products (AGEs), and find out AGEs which enhance effect of TNF-α in PDLSCs might mediate special personality of D-PDLSCs. The adverse effect of AGEs in PDLSCs could be reversed when PDLSCs were treated with DKK1. These results suggested DKK1 mediating WNT signaling might be a therapy target to rescue potential of PDLSCs in periodontitis with diabetes mellitus. PMID:26278788

    Platelet gel biotechnology, a method which has all the components of "tissue engineering" techniques, potentiates the already known healing process of guided tissue regeneration procedures (GTR) by multiplying the number of molecules that activate the healing response and by grafting in the host site various cell types, among which stem cells. Here are reported cases of patients affected by refractory generalized aggressive periodontitis treated with the association GTR and platelet gel biotechnology to verify if the contribution of the gel would produce superior results than those obtained by surgery alone which had been previously applied to the same sites with negative results. Three patients in therapy from 4 to 11 years, already subjected to surgery (GTR) and antibiotic therapy, were reoperated with the adjunct of autologous platelet gel. At a distance of 15.2 months (range 11-17 months) the operated sites showed a reduction in probing pocket depth of 3.4 mm (range 2.8-4.8 mm) and a gain in clinical attachment level of 3.1 mm (range 3-3.5 mm). The association of platelet gel biotechnology with GTR in the surgical treatment of intrabony defects of refractory generalized aggressive periodontitis patients seems to produce results similar to those reported for patients with chronic adult periodontitis. The observations at 15.2 months indicate that there is a stability over time of the results in those sites where previous surgical therapy had shown relapse.

    Objectives Although several studies have addressed the relationship between systemic bone mineral status and the severity of periodontitis, there is little knowledge of the relationship between periodontal disease and locally detected bone mineral density. The aim of this study was to compare the mandibular bone mineral density of patients with chronic periodontitis with that of periodontally healthy subjects. Methods 48 systemically healthy subjects were included in the study and underwent a periodontal examination to determine their status. 24 subjects were periodontally healthy and the other 24 had moderate or severe chronic periodontitis. The mandibular bone mineral density of the subjects was determined by dual energy X-ray absorptiometry. The region of interest on the body of the mandible was independently determined on the dual energy absorptiometry radiographs, and a computer calculated the bone mineral density of these regions. Results The mandibular bone mineral density of the subjects with periodontitis was significantly lower than that of the periodontally healthy subjects (p < 0.01). There were significant negative correlations between the mandibular bone mineral density values and parameters related to the amount of periodontal destruction. Conclusions Low bone mineral density in the jaw may be associated with chronic periodontitis. PMID:22241867

    The aim of the study was to identify clinical microbiological criteria for the necessity of removal of infected epithelium in the periodontal pocket in patients with periodontitis. A total of 90 patients diagnosed with periodontal disease of varying severity were assessed. Clinical examination of the patients was performed, including the definition of index numbers and microbiological diagnosis of the content of periodontal pocket and periodontal tissues by biopsy culture seeding. Epithelial integration of lactobacilli and bifidobacteria was established, indicating the need for a differentiated approach to the removal of gingival epithelium. Diagnostic criteria for deepitalization was identified: marked inflammatory response of periodontal tissues, characterized by performance indexes PMA > 50%, Mulleman > 1.5, Svrakov > 2.7, correlated with the degree of contamination biopsy 4IgKOE/ml and Candida spp. 2IgKOE/ml.

    Diabetes has been associated with periodontitis, but the mechanisms through which periodontal diseases affect the metabolic control remain unclear. Objective This study aimed to evaluate serum leveis of inflammatory markers, IL-8, IL-6 and monocyte chemoattractant protein 1 (MCP-1), in type 2 diabetic patients in the presence of chronic periodontitis. Material and Methods Forty two individuals were enrolled in this study and assigned to one of five groups: diabetes mellitus with inadequate glycemic control and periodontitis (DMI+P, n = 10), diabetes mellitus with adequate glycemic control and periodontitis (DMA+P, n = 10), diabetes mellitus without periodontitis (DM, n = 10), periodontitis without diabetes (P, n=6), and neither diabetes nor periodontitis (H, n = 6). Periodontal clinical examination included visible plaque index (PL), gingival bleeding index (GB), probing depth (PD), attachment level (AL) and bleeding on probing (BP). Glycemic control was evaluated by serum concentration of glycated hemoglobin (HbAlc). Inflammatory serum markers IL-8, IL-6 and (MCP-1) were measured by ELISA. Results DMI+P and DMA+P groups presented higher PD (p=0.025) and AL (p=0.003) values when compared to the P group. There were no significant differences among groups for IL-6, IL-8 and MCP-1 serum levels. Conclusions Although periodontitis was more severe in diabetic patients, the serum levels of the investigated inflammatory markers did not differ among the groups. PMID:24676580

    The article is devoted to investigation of unconscious aggression in patients with multiple sclerosis. We carried out comparison of the relative assessments of metabolism speed of glucose (according to positron emission tomography) and indicators of unconscious aggression (in the Hand test). It is shown that an increased tendency to open aggression (unconscious aggression) in patients with multiple sclerosis, is mainly linked with a reduction in the functioning of different departments of the frontal lobes of the brain on the left and with changes of the metabolism speed of glucose in the structures of the limbic system of the left and right hemisphere. With increasing of unconscious aggression we observed decrease of glucose metabolism speed in certain areas of the lower and middle frontal gyrus.

    The primary goal of nonsurgical periodontal therapy is to control microbial periodontal infection by removing bacterial biofilm, calculus, and toxins from periodontally involved root surfaces. A review of the scientific literature indicates that mechanical nonsurgical periodontal treatment predictably reduces the levels of inflammation and probing pocket depths, increases the clinical attachment level and results in an apical shift of the gingival margin. Another parameter to be considered, in spite of the lack of scientific evidence, is the reduction in the degree of tooth mobility, as clinically experienced. It is important to point out that nonsurgical periodontal treatment presents limitations such as the long-term maintainability of deep periodontal pockets, the risk of disease recurrence, and the skill of the operator. A high number of posttreatment residual pockets exhibiting bleeding on probing and > 5 mm deep are related to lower clinical stability. The successful treatment of plaque-induced periodontitis will restore periodontal health, but with reduced periodontium. In such cases, anatomical damage from previous periodontal disease will persist and inverse architecture of soft tissue may impair home plaque removal. The clinician can select one of the following therapeutic options according to the individual patient's needs: - Quadrant/sextant wise instrumentation (conventional staged debridement, CSD). - Instrumentation of all pockets within a 24-hour period with (full mouth disinfection [FMD]) or without (full mouth scaling and root planing [FMSRP]) local antiseptics. Both procedures can be associated with systemic antimicrobials. -CSD or FMD in combination with laser or photodynamic therapy. Patients with aggressive periodontitis constitute a challenge to the clinician. To date there are no established protocols for controlling the disease. However, data from the literature on the application of the FMD protocol combined with amoxicillin

    Purpose With the increasing prevalence of orthodontic treatment in adults, clear aligner treatments are becoming more popular. The aim of this study was to evaluate the effect of orthodontic treatment on periodontal tissue and to compare orthodontic treatment with fixed appliances (FA) to clear aligner treatment (CAT) in periodontitis patients. Methods A total of 35 patients who underwent orthodontic treatment in the Department of Periodontology were included in this study. After periodontal treatment with meticulous oral hygiene education, patients underwent treatment with FA or CAT, and this study analyzed patient outcomes depending on the treatment strategy. Clinical parameters were assessed at baseline and after orthodontic treatment, and the duration of treatment was compared between these two groups. Results The overall plaque index, the gingival index, and probing depth improved after orthodontic treatment (P<0.01). The overall bone level also improved (P=0.045). However, the bone level changes in the FA and CAT groups were not significantly different. Significant differences were found between the FA and CAT groups in probing depth, change in probing depth, and duration of treatment (P<0.05). However, no significant differences were found between the FA and CAT groups regarding the plaque index, changes in the plaque index, the gingival index, changes in the gingival index, or changes in the alveolar bone level. The percentage of females in the CAT group (88%) was significantly greater than in the FA group (37%) (P<0.01). Conclusions After orthodontic treatment, clinical parameters were improved in the FA and CAT groups with meticulous oral hygiene education and plaque control. Regarding plaque index and gingival index, no significant differences were found between these two groups. We suggest that combined periodontal and orthodontic treatment can improve patients’ periodontal health irrespective of orthodontic techniques. PMID:26734489

    The detection of salivary biomarkers has a potential application in early diagnosis and monitoring of periodontal inflammation. However, searching sensitive salivary biomarkers for periodontitis is still ongoing. Oxidative stress is supposed to play an important role in periodontitis progression and tissue destruction. In this cross-sectional study, we investigated total antioxidant capacity (TAC) and total oxidant status (TOS) in saliva of periodontitis patients compared to healthy controls and their relationship with periodontopathic bacteria and periodontal disease severity. Unstimulated saliva was collected from 45 patients with generalized severe periodontitis and 37 healthy individuals and the TAC/TOS were measured. In addition, salivary levels of Aggregatibacter actinomycetemcomitans, Porphyromonas gingivalis, Tannerella forsythia, Treponema denticola, and Fusobacterium nucleatum in saliva were measured. Salivary TAC was lower in periodontitis patients compared to healthy controls. Moreover, a significant negative correlation of salivary TAC with clinical attachment loss was observed in periodontitis patients. No significant difference in the salivary TOS was observed between periodontitis patients and healthy controls. Bacterial load was enhanced in periodontitis patients and exhibited correlation with periodontal disease severity but not with salivary TAC/TOS. Our data suggest that changes in antioxidant capacity in periodontitis patients are not associated with increased bacterial load and are probably due to a dysregulated immune response. PMID:26779448

    Aim: Anemia of chronic disease is defined as anemia occurring in chronic infections and inflammatory conditions that is not caused by marrow deficiencies or other diseases and in the presence of adequate iron stores and vitamins. The present case control study was aimed to assess the red blood cell parameters for signs of anemia in patients with mild, moderate, and severe chronic periodontitis. Materials and Methods: A simple random sampling method was used to select 80 healthy male patients, who were divided into four groups based on full mouth periodontal examination as follows: group I patients comprised the control group (n = 20), which included patients with a clinically healthy periodontium, group II patients (n = 20) were diagnosed with mild chronic periodontitis, group III (n = 20) included moderate chronic periodontitis patients, and patients with severe chronic periodontitis formed group IV (n = 20). Laboratory blood investigations included total number of erythrocytes, hemoglobin concentration, packed cell volume, mean corpuscular volume, mean corpuscular hemoglobin, and mean corpuscular hemoglobin concentration. Results: Data analysis showed a statistically significant decrease in red blood cell parameters with increase in different grades of periodontitis. Conclusion: Results of the present study show a substantial decrease in red blood cell parameters with increase in the severity of periodontal destruction. PMID:26759801

    In several large epidemiological studies chronic periodontitis has been implicated as an additional risk factor, independent of other risk factors, for the development of ischaemic heart disease. The underlying mechanism is thought to be a localised infection giving rise to an inflammatory host response, and some experimental data agree with this hypothesis. Recently, however, some studies have questioned the post dated relationship between the two diseases. The current case-record study was undertaken to evaluate the prevalence of chronic periodontitis and the severity of such periodontal disease in a heart transplant population, assuming the latter represented a relatively severely compromised cardiovascular patient population. The study demonstrated that 76% of the patients had various degrees of periodontal disease prior to undergoing a heart transplant. Thus, it is possible that a relationship between cardiovascular disease and periodontal disease exists, but further, large intervention studies will be needed to confirm such a conclusion.

    Accurately predicting inpatient aggression is an important endeavor. The current study investigated inpatient aggression over a six-month time period in a sample of 152 male forensic patients. We assessed constructs of psychopathy, anger, and active symptoms of mental illness and tested their ability to predict reactive and instrumental aggression. Across all levels of analyses, anger and active symptoms of mental illness predicted reactive aggression. Traits of psychopathy, which demonstrated no relationship to reactive aggression, were a robust predictor of instrumental aggression. This study (a) reestablishes psychopathy as a clinically useful construct in predicting inpatient instrumental aggression, (b) provides some validation for the reactive/instrumental aggression paradigm in forensic inpatients, and (c) makes recommendations for integrating risk assessment results into treatment interventions.

    The aim of this systematic literature review was to evaluate which type of periodontal preventive and therapeutic approaches presents superior outcomes in patients with Down syndrome (DS). Studies reporting different methods of periodontal care from DS patients were considered eligible. Included clinical studies should indicate at least two periodontal parameters in different periods of assessment. Screening of the articles, data extraction and quality assessment were conducted independently and in duplicate. Electronic search according to the PICO search, with both Key-words and MESH terms were conducted in MEDLINE, EMBASE and CENTRAL databases until March 2016. Manual search was conducted in four journals, namely Journal of Periodontology, Journal of Clinical Periodontology, Journal of Periodontal Research and Special Care in Dentistry and their electronic databases were searched. Electronic and manual search resulted in 763 papers, and of them 744 were excluded after title/abstract assessment. The full text of 19 potentially eligible publications was screened and 9 studies met inclusion criteria. The results demonstrated the importance to introduce youngest DS patients in preventive programs, as well as participation of parents, caregivers or institutional attendants in supervising/performing oral hygiene. In studies with higher frequency of attendance, all age groups presented superior preventive and therapeutic results, irrespective of the therapeutic approach used (surgical/nonsurgical/periodontal care program). The important factors for reducing periodontal parameters were the frequency of the appointments and association with chlorhexidine/plaque disclosing agents as adjuvant treatment. This systematic review demonstrated that early introduction in periodontal care, participation of parents/caregivers/institutional attendants, frequency of attendance and association with chemical adjuvants (independently of the periodontal treatment adopted) seems to

    aim of this study was to evaluate the efficacy of periodontal scaling and oral hygiene instruction for patients with mild chronic periodontitis and rheumatoid arthritis through clinical periodontal parameters and laboratory tests for CRP (C- reactive protein) and ESR (erythrocyte sedimentation rate). Twelve individuals with rheumatoid arthritis and 12 healthy individuals were evaluated, with a mean age of 45.38 and 46.75 respectively, all female and with mild, chronic periodontitis. The participants were evaluated clinically and periapical radiographs were taken (T1), after which periodontal treatment was instituted. After ninety days (T2), new clinical and laboratory data were obtained. Probing depth, bleeding index, and plaque indexes were observed in both groups, and the results demonstrated reductions but no statistical differences. Laboratory tests for CRP and ESR produced higher values for the rheumatoid arthritis group with T1- T2 reductions on the average, but the values were still higher than in the health group. We conclude that periodontal therapy in patients with rheumatoid arthritis and mild chronic periodontitis showed a improvement in the periodontal clinical parameters and laboratory tests that were evaluated.

    The objective of this study was to investigate the salivary proteins that are associated with periodontitis in patients with Type 2 diabetes mellitus (T2DM). Volunteers for the study were patients from the Diabetic Unit, University of Malaya Medical Centre, whose periodontal status was determined. The diabetic volunteers were divided into two groups, i.e., patients with periodontitis and those who were periodontally healthy. Saliva samples were collected and treated with 10% TCA/acetone/20 mM DTT to precipitate the proteins, which were then separated using two-dimensional polyacrylamide gel electrophoresis. Gel images were scanned using the GS-800TM Calibrated Densitometer. The protein spots were analyzed and expressed in percentage volumes. The percentage volume of each protein spot was subjected to Mann-Whitney statistical analysis using SPSS software and false discovery rate correction. When the expression of the salivary proteins was compared between the T2DM patients with periodontitis with those who were periodontally healthy, seven proteins, including polymeric immunoglobulin receptor, plastin-2, actin related protein 3, leukocyte elastase inhibitor, carbonic anhydrases 6, immunoglobulin J and interleukin-1 receptor antagonist, were found to be differentially expressed (p < 0.01304). This implies that the proteins may have the potential to be used as biomarkers for the prediction of T2DM patients who may be prone to periodontitis. PMID:22606001

    Periodontal disease (PD) is induced by a complex microbiota, such as Porphyromonas gingivalis, Tannerella forsythia, and Treponema denticola (together called the red complex), which triggers intense inflammatory reaction. Down syndrome (DS) individuals demonstrate a high prevalence of PD compared with those who are otherwise chromosomally normal (euploids). This pilot study aimed to evaluate the effect of non-surgical periodontal treatment in DS chronic periodontitis patients on clinical and microbiological parameters. Patients with chronic periodontitis, 23 DS and 12 euploids (control group), were submitted to non-surgical mechanical periodontal treatment, followed by maintenance for 45 days. Clinical parameters after periodontal treatment were similar in diseased and healthy sites, independent of the genetic background. Diseased sites of DS and control patients harbored similar levels of P. gingivalis and T. forsythia at baseline, but significantly higher levels of T. denticola were found in DS patients. Increased levels of P. gingivalis at healthy sites were found in DS individuals. Non-surgical periodontal therapy decreased the levels of red complex microorganisms and improved the tested clinical parameters of diseased sites in both groups. However, the levels of red complex bacteria were higher in diseased sites of DS patients after the periodontal treatment. We conclude in this pilot study that, although the mechanical periodontal treatment seemed to be effective in DS subjects over a short-term period, the red complex bacteria levels did not decrease significantly in diseased sites, as occurred in controls. Therefore, for DS patients, it seems that the conventional non-surgical periodontal therapy should be improved by utilizing adjuvants to reduce the presence of periodontopathogens.

    Objectives. This study was undertaken to investigate the OPG profiles in gingival crevicular fluid (GCF), saliva, and gingival tissues of chronic periodontitis (CP) patients in response to open flap debridement (OFD). Subjects and Methods. The study included 30 subjects divided into 2 groups: 20 CP patients and 10 periodontally healthy subjects. Plaque index, gingival index, pocket depth, and clinical attachment level measurements were recorded for all subjects. GCF, salivary, and gingival samples were collected from all 30 subjects at baseline and 3 and 6 month after OFD from the 20 CP patients. GCF and salivary OPG levels were assessed by ELISA assay, while OPG expression in gingival tissues was examined by immunohistochemistry. Results. GCF, salivary and gingival OPG profiles were significantly higher in control subjects compared to CP patients at baseline (P < 0.001). Within CP group, OPG levels in GCF, saliva, and gingival samples showed a significant increase at 3 and 6 months after OFD (P < 0.001) compared to baseline. Although OPG values increased significantly in gingival samples and insignificantly in saliva after 3 months compared to 6 months, yet GCF levels were significantly decreased. Conclusions. OPG might be considered as a diagnostic and prognostic biomarker of periodontal bone destruction. This trial is registered with NCT02160613. PMID:25814780

    Increased arterial stiffness (AS) is an important indicator for atherosclerotic cardiovascular disease (ACVD). Epidemiologically, periodontitis and ACVD are associated. Therefore, we aimed to investigate AS in periodontitis patients and controls. In addition, we explored the effect of periodontal therapy on AS in a sub-group of cases. Pulse-wave velocity (PWV), a non-invasive chair-side function test for AS, was measured in periodontitis patients (n=57; mean age 46.6 years) and compared with a reference group (n=48; mean age 45.5 years). In addition, 45 cases (mean age 46.9 years) were 6 months followed after periodontal treatment, to explore a possible effect on arterial function. Periodontitis patients showed a significantly increased PWV compared with the reference group (8.01±0.20 vs. 7.36±0.22 m s(-1) respectively; P=0.029) and this remained significant after adjustments for ACVD risk factors (P=0.019). After periodontal therapy, no significant reduction in PWV was seen (8.00±1.8 to 7.82±1.6 m s(-1); P=0.13), but systolic blood pressure (SBP) was significantly reduced (119.8±14.6 to 116.9±15.1 mm Hg; P=0.040). It can be concluded that periodontitis is associated with increased AS. This confirms with a new parameter the association of periodontitis with ACVD. Although periodontal treatment did not lower AS significantly, a modest reduction of SBP after 6 months was observed.

    Abstract Treatment of periodontal diseases has been associated with benefit outcomes for patients with chronic obstructive pulmonary disease (COPD). However, no population-based cohort study has been conducted. We evaluated this relationship by retrospective cohort study using a large population data. Using the National Health Insurance claims data of Taiwan, we identified 5562 COPD patients with periodontal diseases who had received periodontal treatment as the treatment group. The comparison group was selected at a 1:1 ratio matched by the propensity score estimated with age, sex, date of COPD diagnosis and periodontal treatment, and comorbidities. Both groups were followed up for 5 years to compare risks of acute exacerbation, pneumonia, and acute respiratory failure. The incidence rates of adverse respiratory events were significantly lower in the treatment group than in the comparison group: 3.79 versus 4.21 per 100 person-years for emergency room visits, 2.75 versus 3.65 per 100 person-years for hospitalizations, and 0.66 versus 0.75 per 100 person-years for intensive care unit admissions. The treatment group also had a 37% reduced risk of deaths (1.81 vs 2.87 per 100 person-years), with an adjusted hazard ratio of 0.57 (95% confidence interval 0.52–0.62). Periodontal treatment for COPD patients could reduce the risk of adverse respiratory events and mortality. The adequate periodontal health care is important for COPD patients with periodontal diseases. PMID:27196497

    Background Diacylglycerol (DAG), levels of which are tightly regulated by diacylglycerol kinases (DGKs), is a lipid mediator linked to key biologic functions. Members of the DGK family undergo alternative splicing, generating the protein diversity necessary to control different intracellular DAG pools. DGKα function is altered in polymorphonuclear neutrophils (PMNs) of patients with localized aggressive periodontitis (LAgP), suggesting a genetic basis. Here, the authors assess DGKα spliced transcripts in human LAgP neutrophils. Methods In an expression library of a patient with LAgP, PMNs were screened for different DGKα transcripts. Real-time polymerase chain reaction and in vitro expression assays were performed to assess the fate of different transcripts on protein translocation and superoxide production in human leukemia cells (HL-60) and COS-7 cells. Results A DGKα transcript that lacks exon 10 (DGKαΔ10) and generates a premature stop codon and a truncated protein was identified as being upregulated in LAgP neutrophils. In vitro assays revealed that DGKαΔ10 translocation occurred even in the absence of important regulatory motifs. Transfection of HL-60 neutrophil-like cells with the DGKαΔ10 spliced variant induced an increase in the stimulated production of su-peroxide anion replicating the phenotype of LAgP PMNs. Conclusion DGKαΔ10 can act as a dominant-negative transcript that can modulate superoxide production and provides an example of genetic regulation of the inflammatory response that may be relevant to human inflammatory diseases such as LAgP.

    The author describes his experiences in treating violent patients in group therapy. Problems include the divergent goals of therapist, patient, and society; the environmental limitations on incarcerated patients; countertransference issues; and magical expectations on the part of patients. Therapeutic goals must be somewhat limited with patients who are forced into therapy. It may be dangerous to "open up" such patients, especially when they face lengthy prison terms. The author suggests that distancing tactics be avoided with violent patients, who need to encounter another person who has dealt successfully with hatred, fear, and limitations.

    Patients treated with adrenal glucocorticoids may run a higher risk of dental caries, both as a result of their medical condition and of the physical and physiological effects of their pharmacotherapy. Our clinical study reports about patients treated with glucocorticoids who were also having an odonto-periodontal condition. They were examined and we found rampant caries and periodontal diseases. The slow evolution of asymptomatic periodontal disease encouraged destruction of teeth in root caries. The rampant caries were correlated with immunodeficiency and treatment of these caries must take into account the general treatment.

    Periodontitis impairs the osteogenic differentiation of human periodontal mesenchymal stem cells (hPDLSCs), but the underlying molecular mechanisms are still poorly understood. Long noncoding RNAs (lncRNAs) have been demonstrated to have significant roles under both physiologic and pathological conditions. In this study, we performed comprehensive lncRNA profiling by lncRNA microarray analysis and identified a novel lncRNA, osteogenesis impairment-related lncRNA of PDLSCs from periodontitis patients (lncRNA-POIR), the expression of which was significantly decreased in PDLSCs from periodontitis patients (pPDLSCs) and was upregulated by osteogenic induction. To study the functions of lncRNA-POIR, we prepared cells with overexpression and knockdown of lncRNA-POIR and found that lncRNA-POIR positively regulated osteogenic differentiation of hPDLSCs and pPDLSCs both in vitro and in vivo. Using quantitative real-time PCRs (qPCRs) and luciferase reporter assays, we demonstrated that lncRNA-POIR may act as a competing endogenous RNA (ceRNA) for miR-182, leading to derepression of its target gene, FoxO1. In this process, lncRNA-POIR and miR-182 suppress each other and form a network to regulate FoxO1. FoxO1 increased bone formation of pPDLSCs by competing with TCF-4 for β-catenin and inhibiting the canonical Wnt pathway. Finally, inflammation increases miR-182 expression through the nuclear factor-κB pathway, and the miR-182 overexpression in the inflammatory microenvironment resulted in an imbalance in the lncRNA-POIR-miR-182 regulatory network. In conclusion, our results provide novel evidence that this lncRNA-miRNA (microRNA) regulatory network has a significant role in osteogenic differentiation of pPDLSCs and that it has potential as a therapeutic target in mesenchymal stem cells during inflammation.

    Background: Although the interleukin-1 (IL-1) plays a critical role in the pathogenesis of periodontitis, associations between IL1 gene cluster polymorphisms and the disease remains unclear. Aims: To investigate the importance of IL1B-511C>T (rs16944), IL1B +3954C>T (rs1143634), and IL1RN intron 2 variable number tandem repeat (VNTR) (rs2234663) polymorphisms, individually or in combination, as the risk factors of periodontitis in a Southeastern Brazilian population with a high degree of miscegenation. Subjects and Methods: A total of 145 individuals, with aggressive (aggressive periodontitis [AgP], n = 43) and chronic (chronic periodontitis [CP], n = 52) periodontitis, and controls (n = 50) were genotyped by polymerase chain reaction (PCR) (IL1RN intron 2 VNTR) or PCR-restriction fragment length polymorphism (PCR-RFLP) (IL1B-511 C>T and IL1B + 3954C>T) techniques. Statistical Analysis: The independent t-test, Chi-square, and Fisher's exact tests were used. The SNPStats program was used for haplotype estimation and multiplicative interaction analyses. Results: The IL1B +3954T allele represented risk for CP (odds ratio [OR] = 2.84), particularly in smokers (OR = 4.43) and females (OR = 6.00). The minor alleles IL1RN*2 and *3 increased the risk of AgP (OR = 2.18), especially the IL1RN*2*2 genotype among  white Brazilians (OR = 7.80). Individuals with the combinations of the IL1B + 3954T and IL1RN*2 or *3-containing genotypes were at increased risk of developing CP (OR = 4.50). Considering the three polymorphisms (rs16944, rs1143634, and rs2234663), the haplotypes TC2 and CT1 represented risk for AgP (OR = 3.41) and CP (OR = 6.39), respectively. Conclusions: Our data suggest that the IL1B +3954C>T and IL1RN intron 2 VNTR polymorphisms are potential candidates for genetic biomarkers of periodontitis, particularly in specific groups of individuals.

    Background: Although the interleukin-1 (IL-1) plays a critical role in the pathogenesis of periodontitis, associations between IL1 gene cluster polymorphisms and the disease remains unclear. Aims: To investigate the importance of IL1B-511C>T (rs16944), IL1B +3954C>T (rs1143634), and IL1RN intron 2 variable number tandem repeat (VNTR) (rs2234663) polymorphisms, individually or in combination, as the risk factors of periodontitis in a Southeastern Brazilian population with a high degree of miscegenation. Subjects and Methods: A total of 145 individuals, with aggressive (aggressive periodontitis [AgP], n = 43) and chronic (chronic periodontitis [CP], n = 52) periodontitis, and controls (n = 50) were genotyped by polymerase chain reaction (PCR) (IL1RN intron 2 VNTR) or PCR-restriction fragment length polymorphism (PCR-RFLP) (IL1B-511 C>T and IL1B + 3954C>T) techniques. Statistical Analysis: The independent t-test, Chi-square, and Fisher's exact tests were used. The SNPStats program was used for haplotype estimation and multiplicative interaction analyses. Results: The IL1B +3954T allele represented risk for CP (odds ratio [OR] = 2.84), particularly in smokers (OR = 4.43) and females (OR = 6.00). The minor alleles IL1RN*2 and *3 increased the risk of AgP (OR = 2.18), especially the IL1RN*2*2 genotype among  white Brazilians (OR = 7.80). Individuals with the combinations of the IL1B + 3954T and IL1RN*2 or *3-containing genotypes were at increased risk of developing CP (OR = 4.50). Considering the three polymorphisms (rs16944, rs1143634, and rs2234663), the haplotypes TC2 and CT1 represented risk for AgP (OR = 3.41) and CP (OR = 6.39), respectively. Conclusions: Our data suggest that the IL1B +3954C>T and IL1RN intron 2 VNTR polymorphisms are potential candidates for genetic biomarkers of periodontitis, particularly in specific groups of individuals.

    Aim: To evaluate the effect of non-surgical periodontal therapy on plasma lipid levels in hyperlipidemic patients with chronic periodontitis. Materials and Methods: After considering the inclusion and exclusion criteria, 30 hyperlipidemic patients with chronic periodontitis in the age group of 30–70 years, undergoing treatment in Ahmed Gasim Cardiac and Renal transplant Centre in north Sudan were recruited for the study. Patients were randomly assigned to the study and control groups. The study group received non-surgical periodontal therapy – oral hygiene instructions, scaling and root planing. The control group participants received only oral hygiene instructions. Lipid profile [total cholesterol (TC), low density lipoprotein (LDL), high density lipoprotein (HDL), triglycerides (TG)], C-reactive protein (CRP), and periodontal parameters [Plaque index (PI), Gingival index (GI), probing pocket depth (PD), and attachment loss (ATL)] were measured and compared at baseline and after 3 months of the respective intervention. Between-groups analysis was done using independent “t” test and within-group analysis was done using dependent “t” test. Results: At baseline, groups were comparable based on lipid profile and periodontal parameters. After 3 months, the control group showed significant decrease in the PI and GI scores while there was no significant change in the other parameters. However, the study group showed significant decrease in the LDL and CRP levels along with a significant decrease in PD, ATL, PI, and GI scores, compared to the baseline values. Conclusion: Local non-surgical periodontal therapy resulted in improved periodontal health, with significant decrease in the LDL and CRP levels in hyperlipidemic patients with chronic periodontitis. Hence, local non-surgical periodontal therapy may be considered as an adjunct in the control of hyperlipidemia, along with standard care. PMID:25984468

    Background The aim of the study was to analyze how metabolic control of type 1 diabetes is related to clinical and microbiological periodontal parameters. Material/Methods The study involved 56 subjects aged from 19 to 50 years divided into 2 groups: healthy subjects (the H group), and diabetic (type 1 diabetes) patients with chronic untreated generalized periodontitis (the DM group). The glycosylated hemoglobin value (HbA1c) was determined using the UniCel DxC 800 SYNCHRON System (Beckman Coulter, USA), and the concentration in blood was measured by the turbidimetric immunoinhibition method. A molecular genetic assay (Micro-IDent plus, Germany) was used to detect periodontopathogenic bacteria in plaque samples. Periodontitis was confirmed by clinical and radiological examination. Results Fusobacterium nucleatum, Capnocytophaga species, and Eikenella corrodens were the most frequently found bacteria in dental plaque samples (77.8%, 66.7%, and 33.4%, respectively), whereas Aggregatibacter actinomycetemcomitans was identified 40.7% less frequently in the DM group than in the H group. The strongest relationship was observed between the presence of 2 periodontal pathogens – F. nucleatum and Capnocytophaga spp. – and poorer metabolic control in type 1 diabetes patients (HbA1c) and all clinical parameters of periodontal pathology. Conclusions Periodontal disease was more evident in type 1 diabetic patients, and the prevalence of periodontitis was greatly increased in subjects with poorer metabolic control. PMID:25294115

    Aims: The aim of this study is to assess the patient compliance to supportive and maintenance periodontal therapy and to determine the reason for noncompliance among young adult patients of Namakkal district, India. Materials and Methods: This was a cross-sectional study conducted on 400 patients who underwent periodontal therapy and subsequently recalled for supportive and maintenance periodontal treatment in the Department of Periodontics, Vivekanandha Dental College for Women, Namakkal. Patients age group 25-35 years and of both gender were equally selected and grouped by occupation and socioeconomic status. According to their compliance with appointments, they are categorized as complete compliance, partially compliance and insufficient or noncompliance. Noncompliance and partially compliance patients were contacted and asked to rate their experience and reason for noncompliance. Results: In this study, 80% of patients showed complete compliance and were regular for supportive periodontal therapy appointments. Women were more regular in maintaining recall appointments than men. Salaried employers showed 84.3% complete compliance, while self-employed personals showed 77% complete compliance and 75% of nonworking personals were regular to the appointment schedule. Noncompliance person has quoted lack of time and forgetting the appointment date as a major reason for missed appointments. Conclusions: This study recommends the need for improvement in communication skills of practitioners and weekend appointment for patient undergoing periodontal maintenance therapy. PMID:25210365

    Abstract Background Diabetes mellitus (DM) increases the risk of periodontitis, and severe periodontitis often coexists with severe DM. The proposed dual pathway of tissue destruction suggests that control of chronic periodontal infection and gingival inflammation is essential for achieving long-term control of DM. The purpose this study is to evaluate the effects of low-level laser therapy (LLLT) by exfoliative cytology in patients with DM and gingival inflammation. Subjects and Methods Three hundred patients were divided in three equal groups: Group 1 consisted of patients with periodontitis and type 1 DM, Group 2 of patients with periodontitis and type 2 DM, and Group 3 of patients with periodontitis (control group). After oral examination, smears were taken from gingival tissue, and afterward all of the patients received oral hygiene instructions, removal of dental plaque, and full-mouth scaling and root planing. A split-mouth design was applied; on the right side of jaws GaAlAs LLLT (670 nm, 5 mW, 14 min/day) (model Mils 94; Optica Laser, Sofia, Bulgaria) was applied for five consecutive days. After the therapy was completed, smears from both sides of jaws were taken. The morphometric analysis was done using the National Institutes of Health Image software program and a model NU2 microscope (Carl Zeiss, Jena, Germany). Results Investigated parameters were significantly lower after therapy compared with values before therapy. After therapy on the side subjected to LLLT, there was no significantly difference between patients with DM and the control group. Conclusions It can be concluded that LLLT as an adjunct in periodontal therapy reduces gingival inflammation in patients with DM and periodontitis. PMID:22928615

    This study investigates the use of saliva, as an emerging diagnostic fluid in conjunction with classification techniques to discern biological heterogeneity in clinically labelled gingivitis and periodontitis subjects (80 subjects; 40/group) A battery of classification techniques were investigated as traditional single classifier systems as well as within a novel selective voting ensemble classification approach (SVA) framework. Unlike traditional single classifiers, SVA is shown to reveal patient-specific variations within disease groups, which may be important for identifying proclivity to disease progression or disease stability. Salivary expression profiles of IL-1ß, IL-6, MMP-8, and MIP-1α from 80 patients were analyzed using four classification algorithms (LDA: Linear Discriminant Analysis [LDA], Quadratic Discriminant Analysis [QDA], Naïve Bayes Classifier [NBC] and Support Vector Machines [SVM]) as traditional single classifiers and within the SVA framework (SVA-LDA, SVA-QDA, SVA-NB and SVA-SVM). Our findings demonstrate that performance measures (sensitivity, specificity and accuracy) of traditional classification as single classifier were comparable to that of the SVA counterparts using clinical labels of the samples as ground truth. However, unlike traditional single classifier approaches, the normalized ensemble vote-counts from SVA revealed varying proclivity of the subjects for each of the disease groups. More importantly, the SVA identified a subset of gingivitis and periodontitis samples that demonstrated a biological proclivity commensurate with the other clinical group. This subset was confirmed across SVA-LDA, SVA-QDA, SVA-NB and SVA-SVM. Heatmap visualization of their ensemble sets revealed lack of consensus between these subsets and the rest of the samples within the respective disease groups indicating the unique nature of the patients in these subsets.

    The aim of the following study is to acquaint medical practitioners with legal possibilities of defense against patients'aggression. The occurrence of the described and discussed issue, namely the appearance of different forms of aggression aimed at physicians and other medical staff is a more and more frequently appearing phenomenon, which is very problematic, and difficult to interpret. The scope of the analysis has been limited to aggression of patients towards physicians only, as they are most often the aim of this aggression, and what should be emphasized, they lack practical and universal solutions and frequently also necessary knowledge to protect themselves against it. The idea behind this study is to present a rational solution to the afore mentioned situation, within legal limits. First, an outline of a conflict situation with a short specification of sources of aggression will be presented, than an appropriate legal taxonomy (including civil and criminal law) allowing for aid in such a situation will be offered and discussed.The authors will also present practical and legally permissible solutions aiming at defense, abandonment, and not allowing for the appearance of this reprehensible phenomenon.

    Background We aimed to investigate the potential genetic relationships between the polymorphisms of gene rs5498 ICAM-1 and rs1041163 VCAM-1 and chronic periodontitis in a Chinese population within Heilongjiang. Material/Methods Genomic DNA was extracted from oral mucosa cells of 584 periodontal patients and 182 healthy individuals. Genotyping of the rs5498 ICAM-1 and rs1041163 VCAM-1 gene polymorphisms was performed with the Multiplex SNaPshot technique. Results Statistically significant associations were identified between the chronic periodontal patients and the controls in the gene polymorphisms of rs5498 ICAM-1 (P=0.007) and rs1041163 VCAM-1 (P=0.029). The distribution of rs5498 (P=0.029) and rs1041163 (P=0.049) differed significantly across the mild, moderate, and severe groups of periodontitis. Conclusions Our findings indicate that ICAM-1 rs5498 and VCAM-1 rs1041163 polymorphisms contribute to chronic periodontitis, and ICAM-1 rs5498 and VCAM-1 rs1041163 gene polymorphisms might be associated with periodontitis severity in the Heilongjiang Chinese population.

    Objectives: Leptin is a hormone-like protein produced by the adipose tissue. It plays an important role in protection of host against inflammation and infection. Some studies have reported changes in leptin levels in the gingival crevicular fluid (GCF), saliva and blood serum of patients with periodontal disease compared to healthy individuals. The aim of the present study was to compare the salivary leptin levels in patients with advanced periodontitis and healthy individuals. Materials and Methods: In this case-control study, the salivary samples of healthy individuals and patients with advanced periodontitis with clinical attachment loss >5mm were obtained using a standardized method and the leptin levels were measured in the salivary samples by means of ELISA. The effects of the periodontal status and sex on the salivary leptin levels of both groups were statistically analyzed by two-way ANOVA. Results: The means ± standard deviation (SD) of salivary leptin levels in healthy subjects and patients with advanced periodontitis were 34.27±6.88 and 17.87±5.89 pg/mL, respectively. Statistical analysis showed that the effect of sex on the salivary leptin levels was not significant (P=0.91), while the effect of advanced periodontitis on the salivary leptin levels was significant compared to healthy individuals (P<0.0001). Conclusions: In patients with advanced periodontitis, the salivary leptin levels were significantly lower compared to healthy individuals. Thus, assessment of salivary leptin can be done as a non-invasive and simple method to determine the susceptibility of patients to advanced periodontitis. PMID:27536322

    Objective: This study compared the effect of 980 Diode laser + scaling and root planing (SRP) versus SRP alone in the treatment of chronic periodontitis. Method: 21 healthy patients with moderate periodontitis with a probing depth of at least 5mm were included in the study. A total of 42 sites were treated during 6weeks with a combination of 980 Diode laser and SRP (21 sites) or SRP alone (21 sites). The gingival index (GI), probing pocket depth (PPD) and bleeding on probing (BOP) were examined at the baseline and after 6 weeks after the start of treatment. Results: Both groups showed statistically significant improvements in GI, BOP and PPD after treatment. The results also showed significant improvement from laser+ SRP group to SRP alone group. Conclusion: The present data suggest that treatment of chronic periodontitis with either 980 Diode laser + SRP or SRP alone results in statistically significant improvements in the clinical parameters. The combination of 980 Diode laser irradiation in the gingival sulcus and SRP, was significantly better as compared to SRP alone.

    Periodontal diseases, which result from inflammation of tooth supporting tissues, are highly prevalent worldwide. Myeloperoxidase (MPO), from certain white blood cells in saliva, is a biomarker for inflammation. We report our study on the salivary MPO activity and its association with severity of periodontal diseases among Thai patients. Periodontally healthy subjects (n = 11) and gingivitis (n = 32) and periodontitis patients (n = 19) were enrolled. Assessments of clinically periodontal parameters were reported as percentages for gingival bleeding index (GI) and bleeding on probing (BOP), whereas pocket depth (PD) and clinical attachment loss (CAL) were measured in millimeters and then made to index scores. Salivary MPO activity was measured by colorimetry using 3,3'-diaminobenzidine as substrate. The results showed that salivary MPO activity in periodontitis patients was significantly higher than in healthy subjects (p = 0.003) and higher than in gingivitis patients (p = 0.059). No difference was found between gingivitis and healthy groups (p = 0.181). Significant correlations were observed (p < 0.01) between salivary MPO activity and GI (r = 0.632, p < 0.001), BOP (r = 0.599, p < 0.001), PD (r = 0.179, p = 0.164), and CAL (r = 0.357, p = 0.004) index scores. Sensitivity (94.12%), specificity (54.55%), and positive (90.57%) and negative (66.67%) predictive values indicate that salivary MPO activity has potential use as a screening marker for oral health of the Thai community.

    We aimed to evaluate the relationship of individual periodontal parameters with the severity of Behçet's disease (BD) and attempt to find the correlation between chronic periodontitis and BD. In this study, 74 registered subjects attending Behçet's clinic with BD symptoms were recruited. The diagnosis was based on the criteria presented by the international study group for BD (ISG) and the total clinical severity score was determined for each patient. All individuals underwent clinical examination to assess oral and periodontal status and presence of oral ulcers. Periodontal clinical parameters of bleeding on probing (BOP), probing depth (PD), and clinical attachment level (CAL) and also hygiene index (HI) and decayed, missing, and filled (DMF) teeth were noted and analyzed to assess the correlation with severity of BD. There was no significant correlation between DMF and severity of BD. The strong association was found between periodontal parameters (BOP, PD, and CAL) and the severity of BD (P < 0.001). It seems that relation of BD to oral health is higher up in severe forms of BD and periodontal diseases. Clinical association between the diseases might be due to a common underlying etiopathogenesis of periodontitis and BD. PMID:27034903

    Recent preclinical and clinical data have suggested the potential benefit of photodynamic therapy (PDT) in the treatment of periodontitis. However, currently, there are very limited data from controlled clinical trials evaluating the effect of PDT in the treatment of periodontitis. The aim of the present study was to evaluate the clinical and microbiological effects of the adjunctive use of PDT in non-surgical periodontal treatment in patients receiving supportive periodontal therapy. Twenty-four patients receiving regularly supportive periodontal therapy were randomly treated with either subgingival scaling and root planing followed by a single episode of PDT (test) or subgingival scaling and root planing alone (control). The following parameters were evaluated at baseline and at 3 months and 6 months after therapy: full mouth plaque score (FMPS), full mouth bleeding score (FMBS), bleeding on probing (BOP) at experimental sites, probing pocket depth (PPD), gingival recession (REC), and clinical attachment level (CAL). Primary outcome variables were changes in PPD and CAL. Microbiological evaluation of Aggregatibacter actinomycetemcomitans (A.a.), Porphyromonas gingivalis (P.g.), Prevotella intermedia (P.i.), Tannerella forsythensis (T.f.), Treponema denticola (T.d.), Peptostreptococcus micros (P.m.), Fusobacterium nucleatum (F.n.), Campylobacter rectus (C.r.), Eubacterium nodatum (E.n.), Eikenella corrodens (E.c.), and Capnocytophaga species (C.s.) was also performed at baseline and at 3 months and 6 months after therapy, using a commercially available polymerase chain reaction test. No differences in any of the investigated parameters were observed at baseline between the two groups. At 3 months and 6 months after treatment, there were no statistically significant differences between the groups in terms of PPD, CAL and FMPS. At 3 months and 6 months, a statistically significantly higher improvement of BOP was found in the test group. At 3 months after therapy

    Marfan syndrome (MFS) is a systemic connective tissue disorder caused by mutations in the extracellular matrix protein fibrillin-1. While it is known that patients with MFS are at high risk of dental disorders and cardiovascular diseases, little information has been provided to date. To clarify the prevalence of periodontitis in patients with MFS, their oral condition and cardiovascular complications were evaluated. The subjects were patients with MFS (n = 40) who attended the University of Tokyo hospital; age- and gender-matched healthy individuals (n = 14) constituted a control group. Cardiovascular complications and full-mouth clinical measurements, including number of teeth, probing of pocket depth (PD), bleeding on probing (BOP), and community periodontal index (CPI) were recorded. MFS patients had more frequent cardiovascular complications (95 %) compared with the controls (0 %). MFS patients had periodontitis (CPI 3 and 4) more frequently (87.5 %) than the age- and gender-matched control subjects (35.7 %). Furthermore, MFS patients had significantly more severe periodontitis (CPI 2.90 ± 0.12 vs 1.64 ± 0.32) and fewer remaining teeth (26.7 ± 0.4 vs 28.4 ± 0.4) compared with the controls. However, PD and BOP were comparable between MFS patients and the control group. A high incidence of periodontitis and cardiovascular complications was observed in Japanese MFS patients.

    Background: Periodontitis is an inflammatory disease characterized by connective tissue breakdown and alveolar bone resorption. Objective: The aim of this study was to make a quantitative evaluation of the gingival tissue components in biopsies from patients with different clinical states of periodontal disease and to determine the relationship between the presence of interleukin-8 and the tissue destruction. Materials and Methods: The study group consisted of 33 biopsies from adult subjects. A total of 25 periodontal patients were sub-classified on the basis of the clinical and radiographic criteria in mild, moderate and advanced periodontitis. Gingival samples were obtained from patients in the course of basic periodontal surgeries as a muco-periostic collate. Data were analyzed by the SPSS system. Results: Collagen fibres decreased as non-specific chronic states increased. A lymphocyte inflammatory infiltrate changed to a lymphoplasmocytary form. Reactivity to interleukin-8 was detected with the severity of the histopathologic diagnoses; however there was no association with the clinical diagnoses. Conclusions: Histopathology and histomorphometry of gingival tissue changed with the degree of inflammation. No evidence of interleukin-8 as a biomarker for clinical diagnoses of periodontitis was obtained. PMID:24872619

    Aggregatibacter actinomycetemcomitans is an important etiologic agent of the periodontitis and is associated with extra-oral infections. In this study, the detection of the ltxA gene as well as the ltx promoter region from leukotoxic A. actinomycetemcomitans isolated from 50 Brazilian patients with periodontitis and 50 healthy subjects was performed. The leukotoxic activity on HL-60 cells was also evaluated. Leukotoxic activity was determined using a trypan blue exclusion method. The 530 bp deletion in the promoter region was evaluated by PCR using a PRO primer pair. A. actinomycetemcomitans was detected by culture and directly from crude subgingival biofilm by PCR using specific primers. By culture, A. actinomycetemcomitans was detected in nine (18%) of the periodontal patients and one (2%) healthy subject. However, by PCR, this organism was detected in 44% of the periodontal patients and in 16% of the healthy subjects. It was verified a great discrepancy between PCR detection of the ltx operon promoter directly from crude subgingival biofilm and from bacterial DNA. Only one periodontal sample harbored highly leukotoxic A. actinomycetemcomitans. Moreover, biotype II was the most prevalent and no correlation between biotypes and leukotoxic activity was observed. The diversity of leukotoxin expression by A. actinomycetemcomitans suggests a role of this toxin in the pathogenesis of periodontal disease and other infectious diseases. PMID:24031284

    Periodontal disease is infectious, complex, multifactorial, chronic inflammatory disease of supporting periodontal tissues that not only alters the bone morphology but also leads to the reduction in bone height. Different types of bony deformities such as horizontal, vertical, craters, and furcation result from periodontal disease, but vertical and Grade II furcation defects are more amenable to regenerative periodontal therapy. The present case report describes the current concept of periodontal diagnosis and the clinical radiographical efficiency of platelet-rich fibrin and hydroxyapatite bioactive glass composite granules graft combination in the management of localized advance osseous defects with respect to tooth number 36 in chronic periodontitis patient at 1 year postoperatively.

    Background: Investigators have identified an association of socio-demographic and medical factors with periodontal risk. This study observed status and association of periodontal disease and associated risk factors/indictors. Materials and Methods: All patients attending a dental teaching hospital were interviewed for socio-demographic and medical information through a structured questionnaire. Participants were examined for periodontal status using the community periodontal index (CPI), by a single examiner during September to November 2012. An association of age, gender, smoking habit, systemic conditions, and oral hygiene measures with periodontal status ([periodontitis CPI score ≥3]/nonperiodontitis [CPI score ≤2]) was analyzed by applying Chi-square test and forward selection stepwise regression analysis. Results: One thousand nine hundred and eighteen patients were examined during the study period. The findings revealed that 63.5% of the subjects had CPI score ≤2 (nonperiodontitis), while 34.5% were found with CPI score ≥3 (periodontitis). Age, gender, occupation, smoking, diabetes, arthritis, cardiovascular disease, kidney disease, stress, medications, and oral hygiene habits of using tooth powder or tooth brushing were significantly (P ≤ 0.037) associated with periodontal status. Regression analysis showed a significant association of age, occupation, and smoking with periodontitis. Conclusion: This study observed prevalence of periodontitis in one-fourth of study sample. The study confirmed various socio-demographic risk factors/indictors associated with increased risk of periodontitis. PMID:26941520

    Aggregatibacter actinomycetemcomitans-induced localized aggressive periodontitis (LAP) in African-American adolescents has been documented but is poorly understood. Two thousand fifty-eight adolescents aged 11 to 17 years were screened for their periodontal status and the presence of A. actinomycetemcomitans in their oral cavity. Seventy-one A. actinomycetemcomitans-negative and 63 A. actinomycetemcomitans-positive periodontally healthy subjects were enrolled, sampled, examined, and radiographed yearly for 3 years. Gingival and periodontal pocket depth and attachment levels were recorded. Disease presentation was characterized by bone loss (BL). Subgingival sites were sampled every 6 months to assess (i) the role of A. actinomycetemcomitans in BL and (ii) the association of A. actinomycetemcomitans and other microbes in their relationships to BL. Sixteen of 63 subjects with A. actinomycetemcomitans developed BL (the other 47 subjects with A. actinomycetemcomitans had no BL). No A. actinomycetemcomitans-negative subjects developed BL. Human oral microbe identification microarray (HOMIM) was used for subgingival microbial assessment. On a subject level, pooled data from A. actinomycetemcomitans-positive subjects who remained healthy had higher prevalences of Streptococcus and Actinomyces species, while A. actinomycetemcomitans-positive subjects with BL had higher prevalences of Parvimonas micra, Filifactor alocis, A. actinomycetemcomitans, and Peptostreptococcus sp. human oral taxon 113 (HOT-113). At vulnerable sites, A. actinomycetemcomitans, Streptococcus parasanguinis, and F. alocis levels were elevated prior to BL. In cases where the three-organism consortium (versus A. actinomycetemcomitans alone) was detected, the specificity for detecting sites of future BL increased from 62% to 99%, with a sensitivity of 89%. We conclude that detecting the presence of A. actinomycetemcomitans, S. parasanguinis, and F. alocis together indicates sites of future BL in LAP. A

  15. Autophagy in periodontitis patients and gingival fibroblasts: unraveling the link between chronic diseases and inflammation

    PubMed Central

    2012-01-01

    Background Periodontitis, the most prevalent chronic inflammatory disease, has been related to cardiovascular diseases. Autophagy provides a mechanism for the turnover of cellular organelles and proteins through a lysosome-dependent degradation pathway. The aim of this research was to study the role of autophagy in peripheral blood mononuclear cells from patients with periodontitis and gingival fibroblasts treated with a lipopolysaccharide of Porphyromonas gingivalis. Autophagy-dependent mechanisms have been proposed in the pathogenesis of inflammatory disorders and in other diseases related to periodontitis, such as cardiovascular disease and diabetes. Thus it is important to study the role of autophagy in the pathophysiology of periodontitis. Methods Peripheral blood mononuclear cells from patients with periodontitis (n = 38) and without periodontitis (n = 20) were used to study autophagy. To investigate the mechanism of autophagy, we evaluated the influence of a lipopolysaccharide from P. gingivalis in human gingival fibroblasts, and autophagy was monitored morphologically and biochemically. Autophagosomes were observed by immunofluorescence and electron microscopy. Results We found increased levels of autophagy gene expression and high levels of mitochondrial reactive oxygen species production in peripheral blood mononuclear cells from patients with periodontitis compared with controls. A significantly positive correlation between both was observed. In human gingival fibroblasts treated with lipopolysaccharide from P. gingivalis, there was an increase of protein and transcript of autophagy-related protein 12 (ATG12) and microtubule-associated protein 1 light chain 3 alpha LC3. A reduction of mitochondrial reactive oxygen species induced a decrease in autophagy whereas inhibition of autophagy in infected cells increased apoptosis, showing the protective role of autophagy. Conclusion Results from the present study suggest that autophagy is an important and shared

    Aplastic anemia is a hematological disorder characterized by pancytopenia. This case report presents a young patient with untreated periodontitis associated with hematological disorders, and cyclosporine therapy. During 2 consecutive days, periodontal therapy which consisted of nonsurgical therapy supplemented with an antibiotic treatment and antifibrinolytic therapy was performed. Commercial microbiological PCR tests and periodontitis IL-1 polymorphism risk test were performed. Following the periodontal therapy, the inflammation was resolved and the patient's occlusion was restored by means of removable partial dentures. After the 5 year follow-up, the patient still remained with shallow probing depths although there was inadequate compliance during the maintenance phase. Aplastic anemia increases the risk of onset of severe forms of periodontitis that can be additionally complicated with cyclosporine therapy. In such patients, periodontal therapy must be supplemented with antibiotics. PMID:27688398

    Background/Aims: A cross-sectional study was undertaken to investigate the association between severity of periodontitis and clinical manifestation of rheumatoid arthritis (RA). Methods: Two hundred sixty-four RA patients and 88 age- and sex-matched controls underwent dental exam. Additionally, clinical manifestations including disease activity and anti-citrullinated protein antibodies were evaluated in RA patients. Results: The prevalence of moderate or severe periodontitis was higher in RA patients compared to controls (63.6% vs 34.1%, p < 0.001). In markers of periodontal inflammation, bleeding on probing was correlated with disease activity score 28 (r = 0.128, p = 0.041), RA disease duration (r = 0.211, p = 0.001), erythrocyte sedimentation rate (ESR; r = 0.141, p = 0.023), anti-cyclic citrullinated peptide antibody (r = 0.183, p = 0.009), and anti-citrullinated α-enolase peptide-1 antibody (r = 0.143, p = 0.025). Gingival index was correlated with RA duration (r = 0.262, p < 0.001), ESR (r = 0.162, p = 0.009), anti-cyclic citrullinated peptide antibody (r = 0.203, p = 0.004) and anti-citrullinated α-enolase peptide-1 antibody (r = 0.225, p < 0.001). Periodontal structural damage represented by probing pocket depth and clinical attachment level were less in RA patients with human leukocyte antigen (HLA)-DRB1 shared epitope compared than those without shared epitope (p = 0.005 and p =0.006, respectively). Conclusions: The prevalence of moderate or severe periodontitis was increased in RA patients compared to controls. Periodontal inflammation was correlated with RA disease duration, ESR, and anti-citrullinated protein antibodies. Periodontal structural damage was less in RA patients with HLA-DRB1 shared epitope.

    The Z-Scan (ZS) technique in the thermal regime has been used to measure the nonlinear optical response of low-density lipoprotein (LDL). The ZS technique is carried out in LDL from 40 patients with chronic periodontitis before and after three, six, and 12 months of periodontal treatment. Clinical parameters such as probing depths, bleeding on probing, total and differential white blood cells counts, lipid profiles, cytokine levels, and antibodies against oxidized LDL are also determined and compared over time. Before the treatment, the ZS experimental results reveal that the LDL particles of these patients are heavily modified. Only after 12 months of the periodontal treatment, the ZS results obtained reveal behavioral characteristics of healthy particles. This conclusion is also supported by complementary laboratorial analysis showing that the periodontal treatment induces systemic changes in several inflammatory markers.

    The aim of this work was to assess the risks and analyse the risk factors for development of chronic periodontitis in Bulgarian patients. The quality of life was investigated in a cohort of 228 patients with chronic periodontitis. Within the frame of this study, pilot research (a case-control study) was conducted among 80 patients (20 cases and 60 control patients without periodontitis) to evaluate the risk for development of chronic periodontitis. The minimum sample size of patients was determined based on power analysis for sample-size calculation. The mean age of participants in the control group was 31.33 ± 9.38 years and in the case group, 33.00 ± 11.52. Data were accumulated by clinical and sociological methods. Descriptive statistics and multi-factor logistic regression analysis (Backward Conditional procedure) were used. One-factor dispersion analysis showed that, of the 12 studied risk factors, the following variables were significant: stress, diabetes, presence of calculus, overlapping and misaligned teeth (P < 0.05). Multiple logistic regressions were applied to evaluate the association between the variables. Three predictors were selected in the final logistic regression equation: diabetes (B = 4.195; P = 0.001), crooked and overlapping teeth (B = 3.022; P = 0.010) and stress (B = 2.882; P = 0.014). The logistic risk assessment model for development of periodontitis has a predictive value of 93.80% (χ2 = 63.91; P = 0.000). Our results confirmed some proven risk factors for periodontal disease. In the studied population, diabetes was the single, most important predictor for development of periodontitis. PMID:26019602

    This study aimed to investigate the effects of nonsurgical periodontal therapy on white blood cell (WBC) count and levels of transforming growth factor beta (TGF—β) in serum from subjects with severe periodontitis. Serum from 28 subjects with periodontitis (mean age: 34.36±6.24; 32% men) and 27 healthy controls (mean age: 33.18±6.42; 33% men) were collected prior to therapy. Blood samples were obtained from 23 subjects who completed therapy (9—12 months). A well—controlled periodontal treatment protocol was established in three stages: mechanical periodontal therapy (scaling and root planning), reinstrumentation of dental sites, and supportive periodontal therapy. Periodontal and systemic parameters such as the total number of WBCs and TGF—β levels, accessed by enzyme—linked immunosorbent assay (ELISA), were included. After therapy, all clinical periodontal parameters decreased (p<0.0001). There were no statistical differences in WBC count between experimental and control groups before or after therapy. However, after therapy, the mean value of lymphocytes in patients with localized aggressive periodontitis (LAgP) was statistically higher than that of patients with generalized chronic periodontitis (GCP) (p<0.0357). Additionally, TGF—β levels in LAgP and GCP patients were higher compared to controls before therapy (p<0.05 and p<0.01, respectively). In LAgP patients, periodontal therapy was associated with increased number of lymphocytes.

    Current approaches in Dutch mental health care institutions towards inpatients' aggression have focused predominantly on environmental factors, such as training the staff in aggression management. However, personality traits might be an important factor in patients' aggression - as shown by incidents in the wards. This study explores the influence of dysfunctional impulsivity and alexithymia on psychiatric patients' aggressive behavior, through self-reports and through involvement in aggressive incidents. Personality traits influencing patients' aggression emphasize the importance of a more direct approach to their aggression. Clinical patients at Dutch mental health care institution Emergis (n=84) filled out questionnaires about their aggressiveness (using Buss and Perry's Aggression Questionnaire Short Form), dysfunctional impulsivity and alexithymia. Multiple regression analyses indicated that dysfunctional impulsivity positively related to self-reported aggressive behavior. The relationship, however, could not be confirmed for inpatients' aggression as reported by the staff on the wards. Unexpectedly affective alexithymia negatively related to hostility. Gender differences in self-reported aggression were found. Female patients showed higher levels of hostility. Regression analyses indicated that the male gender positively related to physical aggression. Findings emphasize the importance of a new approach in Dutch mental health care, in which patients may engage in aggression-regulation training programs. PMID:27387554

    Waardenburg syndrome (WS) is an inherited autosomal dominant genetic disorder presenting variable penetrance and expressivity, with an estimated prevalence of 1:42,000. Clinical characteristics of WS include lateral displacement of the internal eye canthus, hyperplasia of the medial portion of the eyebrows, prominent and broad nasal base, congenital deafness, pigmentation of the iris and skin, and white forelock. A 24-year-old male patient, previously diagnosed with WS, was referred to the Special Needs Dental Clinic of Sacred Heart University, Bauru, Brazil. Parents reported that the patient was experiencing self-mutilation, particularly in the oral region. He presented multiple congenital anomalies, including anophthalmia, mental retardation, low-set ears, and leg deformities. Clinical oral examination revealed hypodontia, abnormalities in dental morphology, extensive dental caries, periodontal disease, and fistulae. Extensive scars on the tongue, lips, and hands caused by self-mutilation were also observed. In accordance with his family and neurologist, full-mouth extraction under general anesthesia was performed, especially considering his severe self-aggressive behavior and the necessity to be fed with soft-food diet due to his inability to chew. After the surgical procedure, a significant reduction in the patient's irritability and gain of weight were reported in the follow-ups of 30, 60, and 180 days. PMID:27659091

    Objective To assess periodontal conditions in patients with early stage CLL and to compare it with the periodontal status of age matched healthy controls and to analyze the relationship between periodontal and hematological parameters in CLL patients. Materials and Methods 60 subjects were examined: 30 patients with CLL Rai 0 (test group) and 30 age-matching healthy individuals (control group). The exclusion criteria were: presence of other systemic disease or condition (e.g. diabetes), history of treatment for periodontitis, use of antibiotics during the last 3 months, use of medications. Socio-demographic data were obtained by means of a questionnaire. Participants with at least 8 teeth underwent a full mouth examination assessing API, PBI, PPD, REC and CAL. Medical data for CLL patients were collected from the patients’ records, while hematological data were obtained from the hemogram. Results Difference between groups was statistically significant for age, number of teeth and frequency of dental checkups (p<0.05). Patients with CLL had significantly higher average values of periodontal indices (API 0.81±0.18; PBI 2.72±0.68; PPD 3.40±0.53; REC 1.95±0.87, CAL 4.37±0.80) compared to the control group (API 0.69±0.15; PBI 1.91±0.45; PPD 2.51±0.40; REC 0.99±0.54; CAL 3.00±0.58). The correlation coefficients between age and periodontal indices showed statistically significance between age and REC (r=0.357; p<0.01), and age and CAL (r=0.295; p<0.05). Age was not statistically significant covariate for CAL (F=2.205; p>0.05), only for REC (F=4.601; p<0.05). After the removal of the statistical effect of age, the difference in REC between CLL and control group remained statistically significant (F=19.732; p<0.01; eta2=0.287). Statistically significant association between periodontal and hematological parameters in CLL patients was not found (p>0.05).

    Objective To assess periodontal conditions in patients with early stage CLL and to compare it with the periodontal status of age matched healthy controls and to analyze the relationship between periodontal and hematological parameters in CLL patients. Materials and Methods 60 subjects were examined: 30 patients with CLL Rai 0 (test group) and 30 age-matching healthy individuals (control group). The exclusion criteria were: presence of other systemic disease or condition (e.g. diabetes), history of treatment for periodontitis, use of antibiotics during the last 3 months, use of medications. Socio-demographic data were obtained by means of a questionnaire. Participants with at least 8 teeth underwent a full mouth examination assessing API, PBI, PPD, REC and CAL. Medical data for CLL patients were collected from the patients’ records, while hematological data were obtained from the hemogram. Results Difference between groups was statistically significant for age, number of teeth and frequency of dental checkups (p<0.05). Patients with CLL had significantly higher average values of periodontal indices (API 0.81±0.18; PBI 2.72±0.68; PPD 3.40±0.53; REC 1.95±0.87, CAL 4.37±0.80) compared to the control group (API 0.69±0.15; PBI 1.91±0.45; PPD 2.51±0.40; REC 0.99±0.54; CAL 3.00±0.58). The correlation coefficients between age and periodontal indices showed statistically significance between age and REC (r=0.357; p<0.01), and age and CAL (r=0.295; p<0.05). Age was not statistically significant covariate for CAL (F=2.205; p>0.05), only for REC (F=4.601; p<0.05). After the removal of the statistical effect of age, the difference in REC between CLL and control group remained statistically significant (F=19.732; p<0.01; eta2=0.287). Statistically significant association between periodontal and hematological parameters in CLL patients was not found (p>0.05). Conclusion The results of this study showed that patients with CLL had worse periodontal status compared to

    Introduction A substantial section of society constituting the mentally ill and psychiatric patients deserve special attention. Evidence has suggested that psychological factors have contributed to an increase in the susceptibility to periodontal disease. Aim The aim of the study was to evaluate the gingival and periodontal health of chronically non-hospitalized psychiatric patients in Mangaluru city, India. Materials and Methods Forty one psychiatric patients having chronic psychiatric illness and on neuroleptic medications for a minimum of 2 years were included in the study. The control group consisted of 41 healthy dental patients who were selected to match the study group by age and gender, and for both groups 20 teeth excluding the third molars should be present. Demographic characteristics, dental examination including gingival index and periodontal health according to the community periodontal index were recorded for each patient in both the groups. Results In the psychiatric patient group (Group A) 47.1% subjects were suffering from schizophrenia and 17.6% subjects were having mood disorder. Gingivitis varied from mild to severe among the patients of both the groups. Bleeding on probing (CPI 1) was recorded in 23.5% in Group A and 14.6% in Group B. Dental calculus (CPI 2) in 38.2% in Group A and 58.5% in Group B of the subjects, 20.6% with at least one 4mm to 5mm pocket (CPI 3), and 17.6% with at least one 6mm pocket (CPI 4). Conclusion The present study underlines a considerable need for prevention and treatment of periodontal disease among chronic psychiatric patients in Mangaluru city. Every effort should be made to increase the awareness of this cohort regarding the importance of oral hygiene practices and on the early diagnosis of periodontal problems. PMID:27656561

    Periodontitis have been referred to as the sixth complication of diabetes found in high prevalence among diabetic patients than among healthy controls. The aim of the present study was to examine the periodontal disease status among collected dental plaque samples. Chromosomal DNA was isolated and amplified by universal primers. The DNA was sequenced for bacterial confirmation and phylogenetic analysis performed for the evolutionary relationship with other known pathogens. No amplification products were observed in groups labeled non periodontal and non Diabetes (NP&ND) and non Periodontal and Diabetes (NP&D). But in the case of Periodontal and non Diabetes (P&ND) groups 22 amplified products were observed. In case of Periodontal and Diabetes (P&D), 32 amplified products were positive for microbes. Among the four microbial groups, Treponemadenticola, and Tannerella forsythia were found to be prevalent in P&D. The phylogenetic analysis of 16s rRNA of Treponemadenticola showed the relationship with other Treponema oral pathogen species and with the Spirochaetazuelaera. Tannerella forsythia shows its evolutionary relationship only with four oral pathogens (Macellibacteroidesfermentans, Porphyromadaceae bacterium, Parabacteroidesmeredae and Bacillus fosythus). Prevotellaintermedia also showed its evolutionary relationship only with Prevotella Spcs while Fusobacterium revealed close evolutionary relationship only with Porpiromonasgingivalis. PMID:24966528

    Dietary supplement use may modify the risk of periodontal disease but effects on wound healing after periodontal procedures are less clear. This study characterized dietary supplement use by male and female patients (n = 376) attending a periodontal clinic-information that is essential for evidence-based intervention studies that may improve patient outcomes after periodontal procedures. Calcium, vitamin D, multivitamin and vitamin C were most commonly used. A greater (p ≤ 0.05) number of males took no supplements compared to females, and more (p ≤ 0.05) females than males took ≥ four supplements. Females took more (p ≤ 0.05) calcium, vitamin D, fish oil, green tea, magnesium, omega 3,6,9 and B vitamin complex. Younger patients (31-50 years) had the highest (p ≤ 0.05) frequency of no supplement use compared to older age groups. Patients over age 50 had a higher (p ≤ 0.05) frequency of using ≥ four supplements including calcium and vitamin D. Supplement use was lower (p ≤ 0.05) in smokers, particularly for calcium, fish oil, green tea and vitamin D. In conclusion, females, older individuals and non-smokers have higher supplement use. Future dietary intervention studies can focus on supplements with known biological activities-anti-inflammatory, antioxidant or osteogenic activity-that may enhance wound healing after reconstructive periodontal procedures.

    Summary Background The anti-inflammatory effects of a homeopathic remedy, Traumeel S, have been observed in experimental and clinical studies; however, its antioxidant properties have not been elucidated. The aim of the present study was to evaluate the antioxidant effects of Traumeel S on peripheral blood neutrophils in patients with periodontitis. Material/Methods The study was performed using venous blood of 22 individuals with chronic periodontitis and 21 healthy subjects. The antioxidant effects of Traumeel S on the production of reactive oxygen species by unstimulated and stimulated with unopsonized E. coli neutrophils were investigated using luminol- and lucigenin-dependent chemiluminescence (CL). Results Polymorphonuclear leukocytes of periodontitis patients produced higher levels (p<0.01) of light output of lucigenin-dependent chemiluminescence and significantly reduced (p<0.01) light output of luminol-dependent chemiluminescence than analogous cells of healthy subjects. Highly diluted (10−4 of the stem solution) Traumeel S significantly (by approximately 50%) reduced superoxide-induced oxidation of lucigenin by unstimulated and stimulated with unopsonized E. coli polymorphonuclear leukocytes of periodontitis patients and had a tendency to intensify luminol-dependent chemiluminescence. Preincubation of the unstimulated and stimulated with unopsonized E. coli polymorphonuclear leukocytes of healthy subjects with Traumeel S exerts no inhibitory action on the luminol- and lucigenin-dependent chemiluminescence of the above-mentioned cells. Conclusions This study indicates that Traumeel S may significantly reduce production of superoxide anion by unstimulated and stimulated peripheral blood polymorphonuclear neutrophils of periodontitis patients.

    Introduction Epidemiological studies show that individuals with periodontitis have a radically amplified threat to develop cardiovascular disease. CRP& TNF-α, are acute phase proteins monitored as a marker of inflammatory status, which have been identified as a major risk factor for atherosclerotic complications. Elevated CRP & TNF-α level in periodontitis patients have been reported by several groups. The present study was performed to determine whether presence of periodontitis and periodontal therapy could influence the serum levels of CRP & TNF-α in cardiovascular disease patients. Methods Forty cardiovascular disease subjects participated in the study. They were classified into two groups. Group A (Control) where no periodontal treatment was given, Group B (Test) where periodontal treatment (scaling & root planing) was performed. Periodontal clinical parameters like OHI-S, probing pocket depth, were evaluated together with serum CRP, TNF-α, at baseline and reassessed after 8 weeks for all the subjects in both the groups. Results The CRP & TNF-α levels in both the groups decreased but the decrease in the Group A was minimal and was not statistically significant (P > 0.05); whereas in Group B where periodontal therapy was performed, there was statistically significant decrease. Conclusion It can be concluded from the study that there can be a possible causal relationship between pathogenesis of periodontal disease and CVD as inferred from the statistical significant outcome in the form of decreased inflammatory biomarkers after the periodontal treatment.

    Background Periodontal disease is common among adults and is associated with an increasing risk of chronic kidney disease (CKD). We aimed to investigate the prevalence and risk factors of CKD in patients with periodontal disease in China. Methods In the current cross-sectional study, patients with periodontal disease were included from Guangdong Provincial Stomatological Hospital between March 2011 and August 2011. CKD was defined as estimated glomerular filtration rate (eGFR) <60 mL/min/1.73 m2, the presence of albuminuria, or hematuria. All patients with periodontal disease underwent a periodontal examination, including periodontal probing pocket depth, gingival recession, and clinical attachment level by Florida Probe. They completed a questionnaire and had blood and urine samples taken. The adjusted prevalence of indicators of kidney damage was calculated and risk factors associated with CKD were analyzed. Results A total of 1392 patients with periodontal disease were invited to participate this study and 1268 completed the survey and examination. After adjusting for age and sex, the prevalence of reduced eGFR, albuminuria, and hematuria was 2.7% (95% CI 1.7–3.7), 6.7% (95% CI 5.5–8.1) and 10.9% (95% CI 9.2–12.5), respectively. The adjusted prevalence of CKD was 18.2% (95% CI 16.2–20.3). Age, male, diabetes, hypertension, history of CKD, hyperuricemia, and interleukin-6 levels (≥7.54 ng/L) were independent risk factors for reduced eGFR. Female, diabetes, hypertension, history of CKD, hyperuricemia, high level of cholesterol, and high sensitivity C-reactive protein (hsCRP) (≥1.03 mg/L) and TNF-α levels (≥1.12 ng/L) were independently associated with an increased risk of albuminuria. Female, lower education (patients with periodontal disease have proteinuria, hematuria, or reduced eGFR, indicating the presence of kidney damage. Whether

    Chronic periodontitis is a multifactorial inflammatory disease that affects supporting structures of the teeth. Although the gingival response is largely described, little is known about the immune changes in the alveolar bone and neighboring tissues that could indicate periodontal disease (PD) activity. Then, in this study we identified the ongoing inflammatory changes and novel biomarkers for periodontitis in the tissues directly affected by the destructive disease in PD patients. Samples were collected by osteotomy in 17 control subjects during extraction of third molars and 18 patients with advanced PD, in which alveoloplasty was necessary after extraction of teeth with previous extensive periodontal damage. Patients presented mononuclear cells infiltration in the connective tissue next to the bone and higher fibrosis area, along with increased accumulation of IL-17+ and TRAP+ cells. The levels of TNF-α and MMP-2 mRNA were also elevated compared to controls and a positive and significant correlation was observed between TNF-α and MMP-2 mRNA expression, considering all samples evaluated. In conclusion, nongingival tissues neighboring large periodontal pockets present inflammatory markers that could predict ongoing bone resorption and disease spreading. Therefore, we suggested that the detailed evaluation of these regions could be of great importance to the assessment of disease progression. PMID:26063981

    Elastase and metalloproteinase-9 (MMP-9) are two of numerous proteolytic enzymes released by neutrophilic granulocytes in the course of periodontitis. The aim of the study was to determine the concentrations of elastase and MMP-9 in saliva in patients with chronic periodontitis compared to healthy individuals. The enzyme-linked immunosorbent assay method was employed to determine the concentrations of elastase and MMP-9 in saliva in patients with chronic periodontitis and with pocket depth (PD) ≥ 6 mm and PD < 6 mm, as well as in saliva of healthy individuals. Significantly higher concentrations of elastase and MMP-9 were observed in patients with periodontitis compared to healthy individuals (p < 0.01). Also a significant difference in elastase concentration in saliva was observed between the PD ≥ 4 mm and PD < 6 mm groups and between the PD ≥ 6 mm and control groups, and statistically significant differences in MMP-9 concentrations between the PD ≥ 6 mm and control groups. No statistically significant differences were observed between the PD < 6 mm and control groups for elastase concentrations in saliva as well as between the PD ≥ 6 mm and PD < 6 mm groups, and also between the PD < 6 mm and control groups for MMP-9 concentrations in saliva. Elastase and MMP-9 concentrations in saliva can be considered as biochemical indicators of severity of periodontitis. PMID:26155148

    This study evaluated the efficacy of implant supported dental restorations in patients with chronic periodontal diseases at various stages within 2 years of completing treatment. 30 patients with periodontal diseases and 30 patients without periodontal diseases were studied. Total counts of 276 implant bodies were divided into group A (patients with periodontal diseases; a total of 149 implants) and group B (patients with healthy periodontium; a total of 127 implants). In group A subjects, periodontitis was treated prior to implant placement. The study focused on patients' modified sulcus bleeding index, modified plaque index, implant mobility index, periodontal probing depth and implant success rate 12 and 24 months after the completion of the treatment. The result show: there were no significant differences in implant success rate between groups A and B; modified sulcus bleeding index scores showed differences between the groups 24 months after treatment; there were no significant differences in other clinical indexes during the study between the groups; there were no significant differences in periodontal probing depth between the groups; modified plaque index and modified sulcus bleeding index were positively correlated in implant supported dental restoration patients with chronic periodontal diseases.

  20. Periodontal conditions in patients with Marfan syndrome – a multicenter case control study

    PubMed Central

    2013-01-01

    Background Marfan syndrome (MFS) is a disorder of the connective tissues. Alterations of the elastic fibers may manifest in different tissues especially in the skeletal, cardiovascular and ocular system. Oral manifestations like orthodontic or skeletal anomalies and fragility of the temporomandibular joint have been well described by various authors. However, no data are available regarding a possible periodontal involvement of MFS. Hence, the aim of the present study was to investigate for the first time if MFS may increase the susceptibility to periodontitis. Methods A comprehensive periodontal examination including documentation of probing pocket depth, gingival recession, clinical attachment level, and bleeding on probing was conducted in all patients. In addition, dental conditions were assessed by determining the Index for Decayed, Missing and Filled Teeth (DMFT) and a self-administered questionnaire was filled out by patients. For statistical analysis, the unpaired t-Test was applied (level of significance: p < 0.05). Both groups were matched concerning well known periodontal risk factors like age, gender and smoking habits. Results 82 participants, 51 patients with MFS (30 female and 21 male, mean age: 40.20 ± 15.35 years) and 31 sound controls (17 female and 14 male, mean age: 40.29 ± 13.94 years), were examined. All assessed periodontal and dental parameters were not significantly different between groups. Conclusions Based on our data, patients with MFS did not reveal a higher prevalence of periodontitis compared to the control group. However, Marfan patients showed a tendency to more inflammation signs, which can be explained by the crowded teeth. Therefore, a regular professional cleaning of the teeth is recommendable (i.e., 6 months intervals) in order to reduce the bacterial biofilm in the oral cavity and thus resulting in a decreased risk of systemic diseases, specifically endocarditis.

    The total of 54 patients with chronic periodontitis of different severity was tested using real-time PCR (Dentoflor kit). The group included 38 patients with chronic gastritis. For the first time, a higher prevalence of Treponema denticola in periodontium of males in comparison with females was demonstrated. The patients with chronic gastritis had more human genome DNA at their periodontium than healthy individuals. Non-parametric statistical analysis demonstrated high association of periodontium colonization with.

    2016-01-01

    Purpose Human saliva, as a vital part of the immune defense system, contains a number of distinct proteins and peptides. Recently human common salivary protein 1 (CSP1) has been identified as an abundant salivary protein and may play a role in promoting the binding of cariogenic bacteria to salivary pellicles. However, nothing else is known regarding the role of CSP1 in periodontology. The aim of this study was to quantify and compare CSP1 levels between healthy subjects and periodontal patients. Methods This controlled clinical study was conducted in periodontally healthy individuals and patients with chronic periodontitis Chonbuk National University Hospital, with Institutional Review Board approval. Whole saliva samples were collected from 36 healthy subjects and 33 chronic periodontitis patients and analyzed. Sodium dodecyl sulfate-polyacrylamide gel electrophoresis and immune blotting were conducted to ensure that anti-CSP1 monoclonal antibody (mAb) binds to CSP1 in human saliva. A sandwich enzyme-linked immunosorbent assay (ELISA) system was house-fabricated using mAb-hCSP1#14 and mAb-hCSP1#4 as a capture and a detector mAb, respectively. The CSP1 concentrations in saliva from 36 healthy subjects and 33 periodontal patients were quantified using the CSP1 sandwich ELISA system, and the results were analyzed using the Student’s t-test. Results Immunoblot analysis using mAb-hCSP1 as a probe confirmed that CSP1 in human saliva existed as a single band with a molecular weight of approximately 27-kDa. The quantification of CSP1 concentrations by CSP1 ELISA showed that the median values (25th to 75th percentiles) of periodontal patients and healthy subjects were 9,474 ng/mL (range, 8,434–10,139 ng/mL) and 8,598 ng/mL (range, 7,421–9,877 ng/mL), respectively. The Student’s t-test indicated the presence of a statistically significant difference between the 2 groups (P=0.024). Conclusions The presence of a significant difference in CSP1 levels between healthy

    A new species of torque teno mini virus, named TTMV-222, was detected in gingival tissue from periodontitis patients using a viral metagenomics method. The 2803-nucleotide genome of TTMV-222 is closely related to TTMV1-CBD279, with 62.6% overall nucleotide similarity. Genetic analyses of the new virus genome revealed a classic genomic organization but a weak identity with known sequences. The prevalence of TTMV-222 in the periodontitis group (n = 150) was significantly higher than that in the healthy group (n = 150) (p = 0.032), suggesting that the new virus may be associated with inflammation in chronic periodontitis patients. However, this finding requires further investigation. PMID:27221159

    Periodontal health states are difficult to quantify and no formal scale quantifying patients' utilities for periodontal health states exits. Multi-attribute utility (MAU) techniques were used to develop such a scale. The MAU scale may be used to quantify patients' assessment of their current periodontal health and that of possible treatment outcomes. Such data, combined with probability values in formal decision analysis techniques would result in improved rationality of treatment planning for periodontal disease. 20 patients attending for routine undergraduate care were interviewed. Data from these interviews were sorted into groups of common interest (domains). Intra-domain health statements were complied from the interview content. 21 patients ranked the intra-domain statements on a scale of 0-100. This same group of patients also performed an inter-domain weighting. Mean results showed that patients were 2X as concerned with how they felt and with the prognosis of possible outcomes, than with how they looked and what facts they knew about their oral health. However, the real value of utilities research lies in application of individual results to treatment planning as there is a wide range of opinion regarding outcome health states. PMID:8891929

    We aimed to evaluate oral hygiene in patients with Parkinson's disease (PD). The incidence of periodontal disease and numbers of caries and remaining teeth were checked in 89 consecutive 60 to 79-year-old patients with PD and compared with two other patient groups: 68 patients with mild neurological disease, and 60 with acute ischemic stroke. Patients with PD had fewer remaining teeth, more caries and a higher incidence of deep periodontal pockets. The frequency of patients with PD with untreated caries was high at Hoehn and Yahr stage II and above, and frequency tended to increase in patients who had low compared to high mini-mental state examination scores. Careful attention should be paid to the oral hygiene of patients with PD, even in the early stages of the disease.

    Background Various studies have shown that non-surgical periodontal treatment is correlated with reduction in clinical parameters and plasma levels of inflammatory markers. The aim of this study was to evaluate the effect of long-term weekly supragingival irrigations with aerosolized 0.5% hydrogen peroxide as maintenance therapy followed by non-surgical periodontal treatment on clinical parameters, plasma levels of inflammatory markers, and morphological changes in gingival tissues of patients with periodontitis. Material/Methods In total, 43 patients with chronic periodontitis were randomly allocated to long-term maintenance therapy. The patients’ periodontal status was assessed using clinical parameters of approximal plaque index, modified gingival index, bleeding index, pocket probing depth, and plasma levels of inflammatory markers (high-sensitivity C-reactive protein and white blood cell count) at baseline and after 1, 2, and 3 years. The morphological status of gingival tissues (immediately after supragingival irrigation) was assessed microscopically. Results Complete data were obtained on 34 patients. A highly statistically significant and consistent reduction was observed in all long-term clinical parameters and plasma levels of inflammatory markers. Morphological data showed abundant spherical bubbles in gingival tissues. Conclusions 1. The present study showed that non-surgical periodontal treatment with long-term weekly supragingival irrigations with aerosolized 0.5% hydrogen peroxide improved clinical periodontal status and plasma levels of inflammatory markers and may be a promising method in periodontology. 2. We found that supragingival irrigation with aerosolized 0.5% hydrogen peroxide created large numbers of spherical bubbles in gingival tissues. PMID:27743448

    This review was designed to determine whether non-surgical periodontal treatment is able to reduce serum glycosylated hemoglobin (HbA1c) levels in patients with diabetes mellitus (DM). Several previous reports showed that scaling and root planning (SRP) improve periodontal status in patients with DM, but whether it also improves metabolic control of the disease is unclear. A systematic review was conducted according to the recommendations of the Cochrane Collaboration and PRISMA. A literature search was conducted in October 2012 using three libraries (Cochrane, Web of Knowledge, and Scopus) and the keywords "periodontal disease" and "diabetes mellitus." Only 21 of the articles met the inclusion criteria for this review. A total of 1,454 patients were thus included in this study to evaluate whether periodontal treatment improved serum HbA1c levels. Both the methodological quality and the risk of bias of each study were taken into account using the Jadad scale. Only ten of the included studies had an acceptable-good score of 3-5. Fourteen of the studies reported a significant decrease in serum HbA1c levels (p < 0.05) after periodontal treatment. The remaining seven studies failed to find a significant decrease in serum HbA1c. The findings of this review suggest that the published literature is insufficient and inconclusive to clearly support periodontal treatment as a means to improve serum HbA1c levels in patients with type 1 DM. It also demonstrates the need for homogeneous studies, with larger samples and longer follow-up periods, to properly address this question.

Epidermal Growth Factor family consists of Amphiregulin, Betacellulin, Epiregulin, Epigen, Heparin binding Epidermal Growth Factor like growth factor and transforming Growth Factor-alpha. Aim The current study aimed to investigate expression of Betacellulin in chronic periodontitis patients with and without type 2 diabetes mellitus and thereby assessing role of betacellulin in periodontal health and disease. Materials and Methods Present study comprised of 90 participants, age ranges from 18 to 60-year-old, for the period of March 2010 to May 2011. Participants were categorized into three groups based Gingival index (GI), probing depth (PD) and clinical attachment loss (CA Loss). Group 1 consisted 30 individuals with clinically healthy periodontium, Group-2 consisted 30 individuals with GI>1, PD≥5 mm, and CA Loss>3 mm. Group-3 (Chronic Periodontitis with type 2 diabetes mellitus) consisted 30 with GI >1, PD≥5 mm, and CA Loss>3 mm. Immunohistochemical localization and quantification of Betacellulin was done in gingival tissue samples from all groups. Results Data showed expression of Betacellulin were higher in chronic periodontitis as compared to healthy. A positive correlation found in Betacellulin expression and Probing Depth in chronic periodontitis. Conclusion This footmark study impacts the role of Betacellulin in pathogenesis and progression of periodontal disease which will help in exploration of novel immunotherapeutic strategies and immunological research activity in this field.

    Introduction The possible hypothesis of a link between periodontitis and rheumatoid arthritis (RA), specifically anti-citrullinated protein antibody (ACPA) positive RA, prompted us to investigate the prevalence of periodontitis in the Swedish Epidemiological Investigation of RA (EIRA), a well-characterised population-based RA case-control cohort. Methods Periodontal status of 2,740 RA cases and 3,942 matched controls was retrieved through linking EIRA with the National Dental Health Registry (DHR), where dental diagnostic- and treatment codes on the adult Swedish population have been registered. Dental records from 100 cases and controls were reviewed to validate the periodontal diagnostic codes in DHR. Results The reviewed dental records confirmed 90% of the periodontitis diagnoses in DHR among RA cases, and 88% among controls. We found the positive predictive value of periodontitis diagnoses in the DHR to be 89% (95% CI 78 to 95%) with a sensitivity of 77% (95% CI: 65 to 86%). In total, 86% of EIRA participants were identified in DHR. The risk for periodontitis increased by age and current smoking status in both cases as well as controls. No significant differences in prevalence of periodontal disease in terms of gingivitis, periodontitis, peri-implantitis or increased risk for periodontitis or peri-implantitis were observed between RA cases and controls. In addition, there was no difference on the basis of seropositivity, ACPA or rheumatoid factor (RF), among patients with RA. Conclusions Our data verify that smoking and ageing are risk factors for periodontitis, both in RA and controls. We found no evidence of an increased prevalence of periodontitis in patients with established RA compared to healthy controls, and no differences based on ACPA or RF status among RA subjects.

    Cardiovascular disease, and particularly ischemic heart disease (IHD), constitutes one of the principal causes of mortality in the western world. Interest has recently increased in the relationship between IHD and different infectious processes as triggering factors of the former, such as Chlamydia pneumoniae and Helicobacter pylori infection. Periodontitis has also been related to an increased risk of coronary disease, since both disorders share common characteristics such as patient age and sex, and a smoking habit, among other aspects. There are many similarities between vascular pathology induced by bacteria and the natural history of atherogenesis. The principal mechanism of action underlying periodontitis and IHD centers on the effect of bacteria and their endotoxins upon inflammatory reaction, hemostasia and lipid metabolic alterations. However, some authors are of the opinion that periodontitis constitutes an epiphenomenon, and that further studies are needed to clarify the cause-effect relation between these two multifactor pathologies.

    The currently recognized principal forms of periodontitis—chronic and aggressive—lack an unequivocal, pathobiology-based foundation. We explored whether gingival tissue transcriptomes can serve as the basis for an alternative classification of periodontitis. We used cross-sectional whole-genome gene expression data from 241 gingival tissue biopsies obtained from sites with periodontal pathology in 120 systemically healthy nonsmokers with periodontitis, with available data on clinical periodontal status, subgingival microbial profiles, and serum IgG antibodies to periodontal microbiota. Adjusted model-based clustering of transcriptomic data using finite mixtures generated two distinct clusters of patients that did not align with the current classification of chronic and aggressive periodontitis. Differential expression profiles primarily related to cell proliferation in cluster 1 and to lymphocyte activation and unfolded protein responses in cluster 2. Patients in the two clusters did not differ with respect to age but presented with distinct phenotypes (statistically significantly different whole-mouth clinical measures of extent/severity, subgingival microbial burden by several species, and selected serum antibody responses). Patients in cluster 2 showed more extensive/severe disease and were more often male. The findings suggest that distinct gene expression signatures in pathologic gingival tissues translate into phenotypic differences and can provide a basis for a novel classification. PMID:24646639

    Background Periodontitis is one of the most common oral diseases associated with the host’s immune response against periodontopathogenic infection. Failure to accurately diagnose the stage of periodontitis has limited the ability to predict disease status. Therefore, we aimed to look for reliable diagnostic markers for detection or differentiation of early stage periodontitis using the immunoprotemic approach. Method In the present study, patient serum samples from four distinct stages of periodontitis (i.e., mild chronic, moderate chronic, severe chronic, and aggressive) and healthy controls were subjected to two-dimensional gel electrophoresis (2-DE), followed by silver staining. Notably, we consistently identified 14 protein clusters in the sera of patients and normal controls. Results Overall, we found that protein levels were comparable between patients and controls, with the exception of the clusters corresponding to A1AT, HP, IGKC and KNG1 (p < 0.05). In addition, the immunogenicity of these proteins was analysed via immunoblotting, which revealed differential profiles for periodontal disease and controls. For this reason, IgM obtained from severe chronic periodontitis (CP) sera could be employed as a suitable autoantibody for the detection of periodontitis. Discussion Taken together, the present study suggests that differentially expressed host immune response proteins could be used as potential biomarkers for screening periodontitis. Future studies exploring the diagnostic potential of such factors are warranted. PMID:27635317

    Periodontitis is a common problem in patients with diabetes mellitus (DM), however, differences in the putative periodontal pathogens in subjects with DM compared to non-DM subjects are still inconclusive. The red complex, which includes Porphyromonas gingivalis, Treponema denticola, and Tannerella forsythia, encompasses the most important pathogens in adult periodontal disease. The aim of the present study was to compare cell numbers of P. gingivalis, T. denticola, T. forsythia and Aggregatibacter actinomycetemcomitans in gingival sulcus of healthy, gingivitis and periodontitis sites of non-diabetes mellitus (NDM), controlled and poorly controlled insulin-dependent DM (CDM and PDM) patients with generalized chronic periodontitis. Subgingival plaque samples were collected from 19 CDM, 19 PDM and 19 NDM patients. Taqman real time-PCR was used to determine bacterial cell number. At subject level, the quantity of red complex bacteria was significantly higher in PDM than those of NDM and positively correlated with HbA1c. At site level (total 342 sites), cell numbers of T. denticola and T. forsythia in healthy sites of CDM and PDM were significantly higher than those of NDM. In gingivitis sites, the numbers of P. gingivalis in CDM and PDM and T. forsythia in PDM were significantly higher than those of NDM while in periodontitis sites, higher quantity of P. gingivalis in PDM was observed. Our study indicated that poor glycemic control is associated with increasing cell numbers of red complex bacteria in subgingival biofilm. PMID:23827459

    Background: Periodontal disease and systemic health are closely associated. However, there is no data supporting the association between periodontal disease and patients with liver diseases associated with hepatitis C virus (HCV) and/or hepatitis B virus (HBV) infection. Objectives: The aim of this study was to evaluate the association between periodontitis and progression of liver diseases in patients with HCV and/or HBV infection. Patients and Methods: In this retrospective study, 351 patients with HCV- and/or HBV-related liver diseases underwent screening for periodontal disease using the Salivaster® salivary occult blood test from February 2010 to June 2014. Furthermore, we examined the prevalence of fimbrillin (fimA) genotype of Porphyromonas gingivalis (P. gingivalis) in 28 HCV-infected patients visited at our hospital between January 2013 and June 2014. P. gingivalis with fimA genotype with types I to V was further detected using a PCR method. Results: Of 351 patients, 76 patients (group 1) had a strong positive result for salivary occult blood test and 275 patients (group 2) had weak positive or negative test results. Significant factors between the groups were obesity, level of AST, ALT, LDH, ALP, Alb, D.Bil, T.cho, AFP, platelets (Plt), IRI, HOMA-IR, current interferon (IFN) treatment and the daily frequency of tooth brushing. Between-groups analysis indicated that total protein (T.pro) level and liver fibrosis were significant factors. According to multivariate analysis, five factors were associated with periodontal disease as Plt count below 80000, brushing teeth only once a day, current IFN treatment, aged 65 years or older and obesity. The adjusted odds ratios for these five factors were 5.80, 3.46, 2.87, 2.50 and 2.33, respectively, and each was statistically significant. Twenty-eight saliva specimens had positive results for P. gingivalis with fimA genotype types I to V. The prevalence of fimA genotype II was higher in 14 patients with liver

    Objective The objective of this case–control study was to quantify the immune responsiveness in individuals with type 2 diabetes (T2D) as compared with patients without diabetes (NT2D) diagnosed with periodontitis. Research Design and Methods Peripheral blood was collected from 20 patients with moderate-to-severe chronic periodontitis (10 T2D, 10 NT2D). Blood samples were stimulated with ultrapure Porphyromonas gingivalis and Escherichia coli lipopolysaccharide (LPS) for 24 hours. 14 cytokines/chemokines were quantified in culture supernatants using multiplex technology. Results T2D individuals demonstrated higher unstimulated levels of interleukin 6 (IL-6), IL-1β, tumor necrosis factor α, interferon γ, IL-10, IL-8, macrophage inflammatory protein 1α (MIP1α), and 1β (MIP1β), and higher stimulated levels of IL-6, IL-8, IL-10, MIP1α and MIP1β, along with lower unstimulated and stimulated levels of granulocyte-macrophage colony-stimulating factor (GM-CSF) when compared with NT2D (p<0.05). Importantly, the LPS-induced levels of IL-6, IL-8, IL-10 and MIP1α strongly correlated with severity of disease, measured by pocket depths (PD), within the T2D group (r2≥0.7, p<0.05), but not within NT2D. Conclusions Among patients with chronic periodontitis, patients with T2D seem to have an enhanced LPS-induced immune responsiveness than individuals without diabetes, which correlates with periodontal disease severity, concomitant with a less robust GM-CSF response. This data may in part explain the higher predisposition to periodontitis in this population. PMID:27651910

    Aim Defensins are cationic antimicrobial peptides expressed in epithelial cells. Such peptides exhibit antibacterial, antifungal and antiviral properties, and are a component of the innate immune response. It has been suggested that they have a protective role in the oral cavity. This study evaluated the DEFB1 polymorphism in diabetic patients with or without periodontitis in comparison to healthy controls. Material and Methods We used Hairpin-Shaped Primer (HP) assay to study the distribution of the -44 C/G SNP (rs1800972) in 119 human DNAs obtained from diabetic patients and healthy control patients. Results The results indicate that there are no differences in distribution between groups and that in diabetic periodontitis patients the homozygous mutant could be found more frequently. Conclusion Further studies are necessary in order to investigate the role of DEFB1 polymorphisms in diabetic periodontitis patients and the influence of the peptide in periodontal pathogens.

    Background: The metabolic syndrome and periodontitis coincide with systemic inflammation and glucose tolerance disorder, which indicate the common pathophysiologic pathway of these diseases. The main goal of this study was to determine the effects of the metabolic syndrome on the periodontal indices of hemodialysis (HD) patient. Materials and Methods: In this descriptive-analytical study, 75 persons were selected by the simple method, 50 of them were HD patients, and 25 of them were healthy people. They were divided into three groups each of which included 25 persons. The periodontal conditions of the selected persons were determined by radiography, gingival index, probing pocket depth, and bleeding index. Then, the periodontal indices of the patients suffering from metabolic syndrome and the persons not affected by metabolic syndrome were compared. At the end, the data were analyzed by SPSS software (version 20) using Mann–Whitney and Kruskal–Wallis tests at the meaningful level of α = 0.05. Since the condition of the unilateral variance test could not be provided for this study, the Kruskal–Wallis test was used. To complete the test, the Mann–Whitney test was used in the binary form among the groups being studied. Results: The obtained results showed a meaningful difference among the groups under study (P < 0.001). The results of the test showed a meaningful difference among the obtained indices of the groups being studied in the binary form (P < 0.001) too. Conclusion: The results of the present study revealed when the severity of chronic systemic disease increased the health of the periodontal tissues would decrease.

    Traumatic Dental Injury (TDI) is often caused by a bruise from a sports-related incident or fall. In individuals with maxillary protrusion, the risk for TDI may be higher. We treated a patient with Hereditary Gingival Fibromatosis (HGF), a rare genetic disorder characterized by proliferative fibrous overgrowth of gingival tissue, who subsequently received a TDI after periodontal surgery. A 13-year-old Japanese boy was referred to the Division of Periodontics at Aichi Gakuin University Dental Hospital in March 2005 with the chief complaint of generalized severe gingival overgrowth involving the maxillary and mandibular arches covering nearly all teeth. Prior to orthodontic treatment, periodontal surgery was performed under general anesthesia in consideration of mastication, dental esthetics, and development. However, soon thereafter in August 2007, the protruded maxillary anterior teeth received an injury while he was playing basketball and the maxillary central incisors showed extrusive luxation. Two weeks after being reset, the maxillary anterior teeth were splinted with wire and adhesive resin cement, and then the splint was removed following evaluations of clinical and radiographic showing signs of normal periodontium. The marginal bone height corresponded to that seen in radiographic findings after the reset and orthodontic treatment was started 1 year later. At the 6-year follow-up examination, the teeth remained asymptomatic, pulpal response to sensitivity tests was normal, and healing was shown in radiographic images. In the present HGF case, we speculated that removal of thick gingiva around the teeth, which might have functioned as a mouth guard, increased the risk for TDI while playing sports. TDI is more likely to occur in patients with exposed protruded misaligned teeth after periodontal surgery. Therefore, it is important for HGF patients with such protruded maxillary anterior teeth to use a mouth guard when participating in sports following

    The periodontal health of 30 adult epileptic patients treated with either sodium valproate or phenytoin was compared with a control group (n = 15) of otherwise healthy patients. The 3 groups were matched for age and sex. Patients on phenytoin therapy showed significantly higher plaque scores (P less than 0.05), gingival index (P less than 0.05) and pocketing (P less than 0.05) than patients in the control group. The % of gingival hyperplasia was significantly higher (P less than 0.05) in the phenytoin-treated patients than those on sodium valproate or in the control group. However, patients on phenytoin therapy had significantly less bone loss than those on sodium valproate (P less than 0.05) or in the control group (P less than 0.01). No significant differences were observed between the sodium valproate group and the control group on any of the parameters assessed. The results from this study would suggest that sodium valproate has no unwanted effects on periodontal health and may be considered a safe alternative, regarding the periodontal aspects, to phenytoin for the treatment of adult onset epilepsy.

    Background Analysis of samplings from periodontal pockets is important in diagnosis and therapy control of periodontitis. In this study, three different sampling techniques were compared to determine if one method can yield samples suitable for reproducible and simultaneous determination of bacterial load, cytokines, neutrophil elastase, and Arg-specific gingipains. R-gingipains are an important virulence factor of Porphyromonas gingivalis, the exact concentration of which in gingival crevicular fluid (GCF) has not yet been quantified. Methods GCF was sampled from four sites per patient (each two sites one method) in 36 chronic periodontitis patients. One week later, the procedure was repeated with alternative methods. The variables that had been determined were: loads of Aggregatibacter actinomycetemcomitans and P. gingivalis, levels of interleukin-6 and interleukin-8, activity of neutrophil elastase and level of R-gingipains. Results The detected cytokine levels were higher using paper strips compared to paper points. Bacteria were found in similar loads from the paper strips and paper points. R-gingipains were detectable in high quantities only by washing of the periodontal pocket. The level of R-gingipains correlated with the load of P. gingivalis. Conclusion The use of paper strips is suitable for simultaneous determination of microbial and immunological parameters. Obtaining GCF by washing can be useful for special purposes. Gingipain concentration in periodontal pockets was directly determined to be up to 1.5 μM. This value indicates that most of so far identified substrates of these proteases by in vitro assays can be easily degraded in P. gingivalis infected sites. PMID:21235330

    Periodontal disease is associated with specific periodontal pathogens and may persist as gingivitis or progress to more severe disease. The bacteria involved in disease initiation and progression have not been identified. We used quantitative polymerase chain reaction (PCR) to compare the levels of Porphyromonas gingivalis, Tannerella forsythia, and Treponema denticola, and total bacteria detected by different sampling methods. On the basis of the results of clinical examinations, 57 patients were divided into 3 groups: healthy group (group A), gingivitis group (group B), and periodontitis group (group C). Bacterial samples were collected from saliva, mouthwash, and by paper-point sampling of gingival crevicular fluid (GCF), and the samples were analyzed with quantitative PCR targeting 16S rRNA. The numbers of total bacteria in samples of GCF, saliva, and mouthwash were 10⁵ to 10⁶, 10⁸, and 10⁷, respectively, per milliliter. The number of P. gingivalis in GCF samples was lower than 10 in group A; however, in groups B and C, the values were 10³ and 10⁴, respectively, indicating that the number of P. gingivalis increased with worsening clinical status. Findings were similar in the samples of saliva and mouthwash. The numbers of T. forsythia showed a pattern similar to that of P. gingivalis in all 3 samples. These results suggest that saliva and mouthwash samples are clinically useful for bacterial testing of periodontal diseases by quantitative PCR. In addition, mouthwash sampling is more feasible and straightforward than saliva sampling.

    The functional and aesthetic restoration of teeth compromised due to aggressive periodontitis presents numerous challenges for the clinician. Horizontal bone loss and soft tissue destruction resulting from periodontitis can impede implant placement and the regeneration of an aesthetically pleasing gingival smile line, often requiring bone augmentation and mucogingival surgery, respectively. Conservative approaches to the treatment of aggressive periodontitis (i.e., treatments that use minimally invasive tools and techniques) have been purported to yield positive outcomes. Here, we report on the treatment and five-year follow-up of patient suffering from aggressive periodontitis using a minimally invasive surgical technique and implant system. By using the methods described herein, we were able to achieve the immediate aesthetic and functional restoration of the maxillary incisors in a case that would otherwise require bone augmentation and extensive mucogingival surgery. This technique represents a conservative and efficacious alternative to the aesthetic and functional replacement of teeth compromised due to aggressive periodontitis. PMID:26649207

    Parkinson's disease (PD) is a progressive neurodegenerative disorder related to the loss or absence of dopaminergic neurons in the brain. These deficits result in slowness of movement, tremor, rigidity, and dysfunction of behaviour. These symptoms negatively influence the patient's capability to carry out the daily oral hygiene manoeuvres. The aim of this work is to record the oral health condition of PD patients evaluated at the IRCSS Bonino-Puleio in Messina. The oral health of 45 consecutive PD patients (study group) with neurologic diagnosis based on United Kingdom Brain Bank Criteria has been compared with that of another 45 no PD patients of the same age (control group). The evaluation of the general oral condition was recorded underlining tooth loss, active periodontal disease, and presence of untreated caries. The frequency of untreated caries, periodontal diseases, and missing teeth of the study group was significantly higher than in control group. Based on the data results, clinicians should direct high attention to the oral hygiene of patients with PD, above all at the early stages of the caries or periodontal disease, in order to prevent serious evolution of those pathologic dental conditions that may finally result in the tooth extraction event.

    Twenty dentulous subjects undergoing clinical therapy for severe periodontitis were used to determine the longitudinal effects of bacterial plaque reduction in vitro lymphocyte transformation. The therapy consisted of either complete extractions or partial extractions and periodontal surgery combined with rigorous oral hygiene. Prior to therapy lymphocytes from these subjects responded significantly to Streptolysin O (SLO) but were not transformed significantly by solubilized dental plaque. However, after therapy lymphocytes from these same subjects responded significantly to both solubilized dental plaque and SLO. This indicates that the severe periodontitis patients were specifically unresponsive to solubilized dental plaque prior to therapy. The mechanism of the unresponsiveness is not clear, but probably does not involve serum factors because supplementation of the lymphocyte cultures with pooled homologous plasma from individuals with gingivitis or moderate periodontitis (instead of the patient's autologous plasma) did not significantly change the mean lymphocyte responses to solubilized dental plaque. In addition, lymphocytes from eleven long-term (5--18 yr) edentulous subjects, who were free of oral inflammation, were significantly transformed by solubilized dental plaque. The latter lymphocyte responses and those of the treated periodontitis patients could be due either to the presence of low levels of oral bacteria in the edentulous mouth or to the lymphocyte transformation assay being a measure of previous antigen sensitization rather than current disease status. In either case, lymphocyte transformation to solubilized dental plaque is not a useful diagnostic tool in periodontitis, but should continue to be a valuable research tool for investigating pathological mechanisms in periodontitis.

    Psychiatric disorders are often associated with disturbed sleep. Poor sleep can attenuate emotional control, including the regulation of aggression, and thus, may increase the risk of impulsive, aggressive acts. This cross-sectional study aimed to investigate the potential contribution of sleep problems to subjective and objective aggressiveness and impulsivity in a forensic psychiatric population. Questionnaires on sleep quality (Pittsburgh Sleep Quality Index), chronic severe insomnia (Sleep Diagnosis List), aggressiveness (Aggression Questionnaire) and impulsivity (Barratt Impulsiveness Scale-11) were completed by 96 forensic psychiatric inpatients, admitted to two forensic facilities in the Netherlands. To obtain more objective measurements of aggression and impulsivity, observational scores on a professional instrument to assess the risk of future aggression (Historical Clinical Future-30) and reported aggressive incidents were collected from files. Results showed that a worse sleep quality and higher insomnia scores were significantly associated with self-reported aggression and impulsivity, clinician-rated hostility and involvement in aggressive incidents within the facility. Whether a participant was professionally judged as impulsive could not be predicted by sleep quality or the insomnia score. To a large extent the results of this study support the hypothesis that poor sleep is related to impulsive, aggressive behavior in forensic psychiatric patients. It is worthwhile to examine the protective effect of treatment of sleep difficulties on aggressive reactivity in (forensic) psychiatric populations. PMID:24184508

    Introduction: The role of serum Monocyte Chemoattractant Protein-1 (MCP-1) as a biomarker of periodontitis is well documented; however, its role in diabetic patients with periodontitis is unknown. Aim: This study was conducted to determine the presence and concentration of serum MCP-1 in diabetic patients with and without periodontitis and correlate it glycemic status with periodontitis. Materials and Methods: Adult diabetic patients were enrolled and grouped into group I, II, and III based on their glycemic status and serum MCP-1 estimated by ELISA. Linear regression and correlation tests were performed using R statistical software, Medcalc software to observe correlation between the serum MCP-1 and glycated hemoglobin level among different groups. Results: Serum samples obtained from 37 patients tested positive for MCP-1. Mean serum MCP-1 concentration was highest (482.3 pg/ml) in group III, lowest (149.3 pg/ml) in group I, and intermediate 398.8 pg/ml in group II. Correlation and regression analysis was done between HbA1c and serum MCP-1. A significant positive correlation (P < 0.001) was observed. Serum MCP-1 increased by 37.278 pg/ml for every 1% rise in HbA1c, and the levels were raised in group II and group III than in group I irrespective of their glycemic status. With an HbA1c range of 6.5-6.9% (group II), the serum MCP-1 values cluster around 380-410 pg/ml. Elevated levels of serum MCP-1 (>500 pg/ml) in three subjects corresponded to HbA1c values more than 12.2% (group III). Conclusion: To our knowledge, this is the first study to document serum MCP-1 levels in diabetic patients with periodontitis. Glycemic status influences serum MCP-1, and lack of glycemic control contributes to increased serum MCP-1 levels. Serum MCP-1 may thus serve as a biomarker of inflammation and disease progression in diabetes with periodontitis. PMID:25143907

    Background: Numerous cross-sectional studies have suggested that chronic periodontitis is a risk factor for cardiovascular diseases. There is evidence that periodontitis and cardiovascular diseases are linked by inflammatory factors including C-reactive protein. The purpose of the study was to investigate the levels of CRP and PNM cells as a marker of inflammatory host response in the serum of chronic periodontitis patients and in patients with CVD. Materials and Methods: Study population included 75 patients; both male and female above 35 years were included for the study. The patients were divided into three groups of 25 each – Group I: Chronic periodontitis patients with CVD, Group II: Chronic periodontitis patients without CVD and Group III: Control subjects (without chronic periodontitis and CVD). Patients with chronic periodontitis had ≥8 teeth involved with probing depth (PD) ≥5 mm involved. The control group had PD ≤ 3 mm and no CVD. Venous blood was collected from the patients and C-reactive protein levels were analyzed by immunoturbidimetry. PMN was recorded by differential count method. Results: On comparison, OHI-S Index, GI, mean PD, CRP and PMN values showed significant difference from Group I to III. CRP level was highly significant in Group I when compared with Group II and Group III. PMN level was highly significant in Group I when compared with Group III PMN level which was not significant. Conclusion: This study indicated that periodontitis may add the inflammation burden of the individual and may result in increased levels of CVD based on serum CRP levels. Thus, controlled prospective trials with large sample size should be carried out to know the true nature of the relationship if indeed one exists. PMID:24049333

    Background: This study investigated gender dependent differences by the comparison of periodontal status and oral hygiene between diabetic patients and non-diabetic subjects. Methods: 517 mostly obese subjects (171 non-diabetic, 205 type 2 diabetic with oral and 141 with insulin therapy; mean: 59 years) completed an oral hygiene questionnaire and had a clinical examination, including periodontal screening and recording (PSR), percentage of bleeding teeth (PBT), probing pocket depth (PD), gingivitis index (GI), and number of teeth (Tn). Main parameters were “periodontitis” and “oral hygiene behaviour”, each defined by 5 sub-parameters. For a comparison of all results, each sub-parameter was set 0.2. The “low performance index“ (LoP) was the sum of significantly worse sub-parameters in the compared groups (maximum of low performing = 1.0). Results: Gender comparison: In non-diabetic and diabetic patients with oral medication, males performed worse (LoP: periodontitis 0.6 - 0.8; oral hygiene 0.4 - 0.6). The male insulin group performed worse oral hygiene (LoP: 0.4) than females with insulin therapy, whereas the periodontal status showed no difference. Diabetic and non-diabetic groups: Females: Diabetic groups performed worse than non-diabetics (LoP: periodontitis 0.2 - 1.0; oral hygiene 0.4). Insulin patients had worse periodontal status and showed no difference in oral hygiene when compared to diabetic patients with oral medication (LoP: 0.2). Males: Diabetic group with oral medication had worse periodontal status than non-diabetics (LoP: 0.6). Conclusions: The periodontal status was mainly due to oral hygiene behaviour, which was worse in men. Apparently behaviour and not diabetes is the major determinant of periodontitis. Men apparently need much more advise than women. PMID:27347232

    Premature exfoliation of primary or permanent teeth in children or adolescents is extremely rare and it can be a manifestation of an underlying systemic disease. This study aims to present the histological aspects associated with early tooth loss in a case of periodontal disease developed without local inflammation and with minimal periodontal pockets and attachment loss. The maxillary left second premolar was extracted together with a gingival collar attached to the root surface. The histological analysis recorded the resorption of the cementum in multiple areas of the entire root surface with the connective tissue of the desmodontium invading the lacunae defects. The connective tissue rich in cells occupied the periodontal ligamentar space and the resorptive areas. No inflammation was obvious in the periodontal ligament connective tissue. This report may warn clinicians about the possibility of the association of cemental abnormalities with early tooth loss.

    This study investigated whether executive dysfunction and impulsivity are both predictors of reactive aggression and is the first to use behavioral assessment of aggression in response to provocation by means of a personalized boxing body opponent bag giving harassing feedback. Aggressive behavior, self-reported aggression, executive functioning (ie, working memory, flexibility, and divided attention), and impulsivity dimensions (i.e., Sensation Seeking, Impulsive Decision Making, and [inadequate] Response Inhibition) were measured in 44 incarcerated psychiatric patients. Results show that both executive functioning (working memory) and impulsivity (Impulsive Decision Making) predicted self-reported reactive aggression, whereas Response Inhibition was the only predictor for reactive aggressive behavioral responses. The study suggests that Response Inhibition is a stronger predictor of reactive aggressive behavior than executive capacities of working memory, flexibility, and divided attention. Therefore, future research should investigate whether (inadequate) Response Inhibition could also be a valuable predictor for violent recidivism. PMID:26894312

    A number of published studies investigated the association between interleukin-1α (IL-1α) −899 (+4845) C→T polymorphism and susceptibility to aggressive periodontitis (AgP). However, the results from different studies are controversial. This study was conducted to further investigate the association between IL-1α −899 (+4845) C→T polymorphism and AgP using a meta-analysis. A search was conducted through PubMed up to May 1, 2013 and a total of 19 relevant case-control studies were identified. The results of this meta-analysis demonstrated that IL-1α −899 (+4845) C→T polymorphism is not associated with susceptibility to AgP under allele T vs. C [odds ratio (OR)=1.00, 95% confidence interval (CI): 0.88–1.14, P=0.98; I2=28.86%] or allele A vs. C comparison (OR=0.99, 95% CI: 0.85–1.14, P=0.85; I2=33.66%). The subgroup analyses based on ethnicity, source of controls and Hardy-Weinberg equilibrium (HWE) also revealed no such association. There existed a weak publication bias (Egger’s test P=0.02). In conclusion, based on the currently available evidence, there is no association between IL-1α −899 (+4845) C→T polymorphism and susceptibility to AgP. PMID:24748978

    Introduction: Periodontal diseases, if left untreated, can lead to tooth loss and affect at least one tooth in 80% of adults worldwide, with the main cause being a bacterial plaque. Among subgingival plaque bacterial species, Porphyromonas gingivalis has been implicated as a major etiological agent causing tooth loss. Diabetics and smokers are two patient groups at high risk for periodontal disease. The increase in the number of this organism with the coexistence of other pathogenic microbes leads to rapid destruction of the periodontium, premature loss of teeth and also because of its virulence has implications in systemic pathology. Our aim was to observe the involvement of P. gingivalis in diabetes mellitus (DM) patients associated with periodontitis with and without tobacco-associated habits and to compare them with periodontitis patients having no other systemic pathologies. Materials and Methods: Subgingival plaque samples from a total of seventy subjects were included in the study. DNA was isolated from the collected sample and was quantified using spectrophotometer for standardizing the polymerase chain reaction. The quantity of the isolated DNA was checked in a ultraviolet-visible spectrophotomer. Statistics: One-way ANOVA and Tukey's multiple post hoc procedures were carried out. Results: The maximum score of P. gingivalis was seen in periodontitis patients having DM, whereas the least score was seen in periodontitis patients having DM with tobacco smoking habit compared to the other groups. Conclusion: P. gingivalis count is significantly reduced in periodontitis patients having DM with smoking habit; it is concluded that P. gingivalis might not be a key causative organism responsible for the periodontal destruction in case of smokers despite the DM condition. The decrease in counts may be attributed to change in the local environment like chemical (tobacco nitrosamines) and physical changes preventing the growth of P. gingivalis. PMID:27721606

    The objective of this study was to determine differences in the pathway of aggressiveness across development between depressive subjects and normal controls, and to examine males and females separately with regard to level of aggression and suicidal behavior among depressed subjects. Participants were classified into 5 groups: depressed suicide attempters (DSA; n = 339), depressed non-suicide attempters (DNSA; n = 92), psychiatric controls who had attempted suicide (PSA; n = 188), psychiatric controls who had not attempted suicide (PNSA; n = 222), and normal controls (NC; n = 532). The level of aggressiveness across development in the different groups was examined using a 5 (DSA vs. DNSA vs. PSA vs. PNSA vs. NC)×3 (Childhood, Adolescence, and Adulthood) MANCOVA. Adjusted and separate models for males and females were conducted. Depressed subjects differed in severity of aggressiveness. The level of aggressiveness in individuals in the NC group remained stable across development, while subjects in the DSA and DNSA groups showed significantly higher levels of aggressiveness. This finding was also observed in subjects of the PSA and PNSA groups. The level of aggressiveness in males with depression significantly increased over time. In women, increasing levels of aggressiveness across development were only observed in depressed suicide attempters. Limitations of this study included use of semi-structured interview for the assessment of risk factors. We found significant differences in severity and in the pathway of aggressiveness across development between depressive subjects and normal controls. In addition, sex differences regarding level of aggression and suicidal behavior among depressed subjects were found.

    ABSTRACT Periodontal disease has been associated with elevations of blood cytokines involved in atherosclerosis in systemically healthy individuals, but little is known about this association in stable cardiovascular patients. The aim of this study was to assess the association between periodontal disease (exposure) and blood cytokine levels (outcomes) in a target population of patients with stable coronary artery disease (CAD). Material and Methods This cross-sectional study included 91 patients with stable CAD who had been under optimized cardiovascular care. Blood levels of IL-1β, IL-6, IL-8, IL-10, IFN-γ, and TNF-α were measured by Luminex technology. A full-mouth periodontal examination was conducted to record probing depth (PD) and clinical attachment (CA) loss. Multiple linear regression models, adjusting for gender, body mass index, oral hypoglycemic drugs, smoking, and occurre:nce of acute myocardial infarction were applied. Results CAD patients that experienced major events had higher concentrations of IFN-γ (median: 5.05 pg/mL vs. 3.01 pg/mL; p=0.01), IL-10 (median: 2.33 pg/mL vs. 1.01 pg/mL; p=0.03), and TNF-α (median: 9.17 pg/mL vs. 7.47 pg/mL; p=0.02). Higher numbers of teeth with at least 6 mm of CA loss (R2=0.07) and PD (R2=0.06) were significantly associated with higher IFN-γ log concentrations. Mean CA loss (R2=0.05) and PD (R2=0.06) were significantly related to IL-10 concentrations. Elevated concentrations of TNF-α were associated with higher mean CA loss (R2=0.07). Conclusion Periodontal disease is associated with increased systemic inflammation in stable cardiovascular patients. These findings provide additional evidence supporting the idea that periodontal disease can be a prognostic factor in cardiovascular patients. PMID:27556206

    Periodontal diseases, which result from inflammation of tooth supporting tissues, are highly prevalent worldwide. Myeloperoxidase (MPO), from certain white blood cells in saliva, is a biomarker for inflammation. We report our study on the salivary MPO activity and its association with severity of periodontal diseases among Thai patients. Periodontally healthy subjects (n = 11) and gingivitis (n = 32) and periodontitis patients (n = 19) were enrolled. Assessments of clinically periodontal parameters were reported as percentages for gingival bleeding index (GI) and bleeding on probing (BOP), whereas pocket depth (PD) and clinical attachment loss (CAL) were measured in millimeters and then made to index scores. Salivary MPO activity was measured by colorimetry using 3,3′-diaminobenzidine as substrate. The results showed that salivary MPO activity in periodontitis patients was significantly higher than in healthy subjects (p = 0.003) and higher than in gingivitis patients (p = 0.059). No difference was found between gingivitis and healthy groups (p = 0.181). Significant correlations were observed (p < 0.01) between salivary MPO activity and GI (r = 0.632, p < 0.001), BOP (r = 0.599, p < 0.001), PD (r = 0.179, p = 0.164), and CAL (r = 0.357, p = 0.004) index scores. Sensitivity (94.12%), specificity (54.55%), and positive (90.57%) and negative (66.67%) predictive values indicate that salivary MPO activity has potential use as a screening marker for oral health of the Thai community.

    Chronic periodontitis is a multifactorial infectious disease associated with Gram-negative anaerobes which are part of the subgingival microflora. In recent years, studies have been conducted to assess the presence of Gram-negative facultative anaerobes (Enterobacteriaceae) and their participation in the development and progression of chronic periodontitis. The aim of this study was to determine the presence of Enterobacteriaceae in patients with chronic periodontitis and gingivitis and to assess antimicrobial susceptibility of clinical isolates. A descriptive, observational study was performed including 64 patients with chronic periodontitis and 22 patients with gingivitis. Microbiological samples were taken from the gingival sulcus using paper points, which then were placed in thioglycollate broth. Samples were incubated for 4 hours at 37 degrees C and finally replated on MacConkey agar Bacteria were identified using the API-20E system (Biomerieux, France) and antimicrobial susceptibility was determined using the disk diffusion method. The evaluation of samples showed presence of 29 enterobacterial species distributed as follows: 7 in the group with gingivitis and 22 in the group with chronic periodontitis. In the chronic periodontitis group the most common species were: K. oxytoca n = 5, S. liquefaciens n = 4 and K. pneumoniae and E. coli with n = 3. The gingivitis group had the highest frequency of Erwinia sp. (n = 2). Clinical isolates showed very low sensitivity levels to beta-lactam ampicillin and amoxicillin/ clavulanic acid, 17.2% and 27.6% respectively, and higher sensitivity levels to ciprofloxacin (96.6%), amikacin (79.3%), gentamicin (68.9%) and ceftazidime, ceftriaxone, kanamycin and trimethoprimsulfa (65.5%). In conclusion, the existence of a high frequency of enterobacteria in patients with chronic periodontitis and gingivitis shows that periodontologists should pay greater attention to prevention protocols, and develop mechanical and antimicrobial

    Aggressiveness is a frequent and problematic aspect of the treatment of forensic patients. This study examines the correlation of aggressiveness and its subtypes with quality of life enjoyment and satisfaction, personality dimensions and family functioning. The research is conducted on 99 psychiatric patients diagnosed with schizophrenia or psychotic disorder similar to schizophrenia (F20-F29) in two forensic psychiatry institutions. The patients committed criminal offence in state of insanity. These offences had signs of aggressive acts and the patients were therefore admitted to inpatient psychiatric forensic institutions. The research was conducted by using the Aggressiveness Questionnaire (AG-87), the Eysenck Personality Questionnaire, the Quality of Life Enjoyment and Satisfaction Questionnaire and the Family Functioning Scale. The results show that aggressiveness has a negative correlation with the quality of life enjoyment and satisfaction. Regression analyses indicate that bad family relations and psychoticism are significant predictors of aggressiveness and its subtypes. We can conclude that forensic patients who committed aggressive offence in psychotic state, who at the same time score higher values on psychoticism scale and report negative family relations, are more likely to express aggressiveness also during their stay in forensic psychiatric hospital.

    samples were measured using spectrophotometric quantitation (dinitrophenyl hydrazine method) and zinc and copper levels were measured using atomic absorption spectrophotometry. Results: The results showed that the levels of vitamin C and zinc decreased and copper levels increased in diabetic patients with periodontits compared to healthy individuals with periodontitis. Conclusion: It may be reasonable to suggest vitamin and/or mineral supplements for patients whose nutrition might be inadequate. Future research should focus on an evaluation of which nutrients may help to prevent the onset and progression of periodontal disease PMID:20922079

    Background Periodontitis is a common, chronic inflammatory disease caused by gram-negative bacteria leading to destruction of tissues supporting the teeth. Epidemiological studies have consistently shown increased frequency, extent and severity of periodontitis among diabetic adults. More recently, some controlled clinical trials have also suggested that periodontal treatment could improve glycaemic control in diabetic patients. However current evidence does not provide sufficient information on which to confidently base any clinical recommendations. The main objective of this clinical trial is to assess whether periodontal treatment could lead to a decrease in glycated haemoglobin levels in metabolically unbalanced diabetic patients suffering from chronic periodontitis. Methods The DIAPERIO trial is an open-label, 13-week follow-up, randomized, controlled trial. The total target sample size is planned at 150 participants, with a balanced (1:1) treatment allocation (immediate treatment vs delayed treatment). Periodontal treatment will include full mouth non-surgical scaling and root planing, systemic antibiotherapy, local antiseptics (chlorhexidine 0.12%) and oral health instructions. The primary outcome will be the difference in change of HbA1c between the two groups after the 13-weeks' follow-up. Secondary outcomes will be the difference in change of fructosamine levels and quality of life between the two groups. Discussion The DIAPERIO trial will provide insight into the question of whether periodontal treatment could lead to an improvement in glycaemic control in metabolically unbalanced diabetic patients suffering from periodontitis. The results of this trial will help to provide evidence-based recommendations for clinicians and a draft framework for designing national health policies.

    Objective Our study sought to evaluate the association between periodontitis and body mass index (BMI) among patients with type 2 diabetes mellitus.  Methods In this cross-sectional case control study analysis of 186 diabetic patients, 112 patients had a body mass index ≥30kg/m2 and 74 control patients had BMI <30kg/m2. All participants underwent oral examinations including a full mouth recording of clinical attachment level (CAL). Information regarding HbA1c levels and high-sensitivity C-reactive protein (hs-CRP) were also gathered.  Results Over half (61%) of patients had a BMI ≥30. Of these 52% had CAL less than 2mm. Multivariate logistic regression analysis showed that there was no association between BMI and CAL. In addition, hs-CRP levels were significantly and positively associated with CAL (OR:1.06, 95% CI: 1.01, 1.12; p=0.007).  Conclusion Among patients with type 2 diabetes mellitus, there was no association between periodontitis and BMI. More studies are needed to further explore this relationship taking into consideration additional lifestyle factors. PMID:25829999

    Association between tumor necrosis factor-α (TNF-α) G-308A (rs1800629) polymorphism and susceptibility to aggressive periodontitis (AgP) were inconsistent, hence we performed this meta-analysis to clarify the association between them using Comprehensive Meta-Analysis v2.2 software. 16 case-control studies were searched from the PubMed, Embase and CNKI databases up to February 2, 2015. The meta-analysis showed a significantly increased risk in A vs. G (OR = 1.23, 95%CI = 1.04–1.44), AA vs. GG (OR = 2.07, 95%CI = 1.11–3.87), and AA vs. AG+GG genetic models (OR = 2.09, 95%CI = 1.13–3.86); however, the non-significantly increased risk was shown in AG vs. GG (OR = 1.06, 95%CI = 0.85–1.32) and AA+AG vs. GG genetic models (OR = 1.06, 95%CI = 0.85–1.31). Cumulative analysis showed that the association changed from non-significant to significant with new studies accumulated and the CIs became more and more narrow, sensitivity analysis indicated results were statistically robust. Stratified analyses of confirmed of HWE, Asians, Caucasians, and population-based controls obtained results similar to that of overall analysis. There was no evidence of publication bias. In summary, current evidence demonstrates that TNF-a G-308A polymorphism might be associated with AgP susceptibility, especially in Asians and Caucasians. PMID:26750615

    A case-control study was conducted on patients with chronic periodontitis (CP) and healthy controls with the aim of evaluating possible association between interleukin 17A (IL17A) G197A (rs2275913) and IL17F T7488C (rs763780) polymorphisms and periodontitis. Genotypes were determined by PCR-RFLP method. Statistical analyses were conducted using the OpenEpi and SNPStas software to calculate Chi-square with Yates correction or Fisher's exact tests, odds ratios (OR), and 95% confidence intervals (CIs). SNPStas software was used to calculate Hardy-Weinberg equilibrium. IL17A AA genotype was more frequent in patients with chronic periodontitis (CP) in the codominant and recessive models (P = 0.09; OR = 2.53 and P = 0.03; OR = 2.46, resp.), the females with CP (P = 0.01, OR = 4.34), Caucasoid patients with CP (P = 0.01, OR = 3.45), and nonsmoking Caucasian patients with CP (P = 0.04, OR = 3.51). The IL17A A allele was also more frequent in Caucasians with CP (P = 0.04, OR = 1.59). IL17F T7488C polymorphism was not associated with chronic periodontitis. In these patients from Southern Brazil, the IL17A rs2275913 polymorphisms, IL17A AA genotype, and the A allele were associated with a susceptibility to chronic periodontitis. PMID:26339129

    3 distinct levels are involved in the periodontal inflammatory process: site, tooth, and individual. By focusing attention on the levels in the population, multilevel or hierarchical modelling (MLM) enables the researcher to understand where and how the effects at the levels involved are occurring. The aim of this paper is therefore to analyse the progression of periodontal disease using analytical models that consider the level hierarchy. 22 patients with periodontitis, in previous reports described as either non-responsive or responsive to periodontal treatment, were investigated. In the multilevel modelling method (MLM), the site pocket probing depth (PPD) is summarised in 3 parameters: the overall mean, the between-individual variance, and the within-individual, between-site variance. The model can readily be extended to include independent variables for sites, teeth and individuals. If these variables are important determinants of PPD, their inclusion in the model will lead to a reduction in residual variances between sites, teeth and individuals. The PPDs were used for construction of a PPD change variable (cPPD). This variable, together with the final registrations of PPD (fPPD) alone, were used as dependent variables in the MLM. Independent predictor variables, 12 on site-level, 3 on tooth-level, and 19 on individual-level, were constructed. The total number of sites assessed was 2236 distributed on 559 teeth in 22 subjects. Initially, a fixed, fully unconditional model (models A and E) was assessed, where no predictor variables were specified at any level. Different random-intercept models (B-D, F-H) were then calculated where the independent variables were inserted in blocks relating to each level. The variance components at all 3 levels were significantly larger than zero. This indicates that MLM is recommended for analysing the present data. The inserted predictors showed 100% sensitivity relating to the subject-level variance. Subsequent testing of the

    The tranquilizing effect of antioxidant mexydol on 95 patients with chrconic generalized parodontitis against a background of various somatic diseases was evaluated. The anxiety and the efficiency of premedication were accessed according to Korach's and Spilberger's scales and according to the special psychological questionnaire. The quantitative characteristics of premedication were given baised on the psychological tests results. There was registered a definite improvement of health characteristics and of patient's mood in comparison to the initial input data as well as lower lever of their situational anxiety. This proves the tranquilizing effect of premedication with mexidol (5% amp.). The most evident dynamics of these changes can be observed among patients suffering from high initial anxiety level. The findings of the study are based on more than 2 year old history of treatment of 30 patients with traumel. 21 patients suffering from disfunction of the nervous system were given some comprehensive treatment (traumel locally orally and mexidol in injections). The clinical effect resulted in emotional stabilization of patients and reduced the time needed for their clinical treatment. The medicines were combined. No side effects were observed.

    Patients with acquired immunodeficiency syndrome (AIDS) are at high risk of opportunistic infections. Oral manifestations have been associated with the level of immunosuppression, these include periodontal diseases, and understanding the microbial populations in the oral cavity is crucial for clinical management. The aim of this study was to examine the salivary bacterial diversity in patients newly admitted to the AIDS ward of the Public Health Clinical Center (China). Saliva samples were collected from 15 patients with AIDS who were randomly recruited between December 2013 and March 2014. Extracted DNA was used as template to amplify bacterial 16S rRNA. Sequencing of the amplicon library was performed using a 454 GS-FLX Titanium sequencing platform. Reads were optimized and clustered into operational taxonomic units for further analysis. A total of 10 bacterial phyla (106 genera) were detected. Firmicutes, Bacteroidetes, and Proteobacteria were preponderant in the salivary microbiota in AIDS patients. The pathogen, Capnocytophaga sp., and others not considered pathogenic such as Neisseria elongata, Streptococcus mitis, and Mycoplasma salivarium but which may be opportunistic infective agents were detected. Dialister pneumosintes, Eubacterium infirmum, Rothia mucilaginosa, and Treponema parvum were preponderant in AIDS patients with periodontitis. Patients with necrotic periodontitis had a distinct salivary bacterial profile from those with chronic periodontitis. This is the first study using advanced sequencing techniques focused on hospitalized AIDS patients showing the diversity of their salivary microbiota. PMID:26191508

    Arterio-venous malformation (AVM) is an abnormal communication between an artery and a vein. The incidence of its occurrence in oral and maxillofacial region is rare, and if present, the most common sign is gingival bleeding. A 12-year-old female patient presented with an extra oral swelling in relation with upper lip. Intra oral examination showed non tender gingival swelling with spontaneous bleeding associated with maxillary arch. On initiation of phase I therapy using hand instruments, spontaneous brisk bleeding was encountered which was difficult to control. Because of severe nature of hemorrhage encountered, some type of vascular abnormality was suspected. Ultrasonography followed by angiography confirmed AVM in relation with upper lip. Embolization of lesion was followed by gingivectomy procedure and no recurrence was reported during one year of follow-up. Thus, proper recognition and therapeutic intervention is essential to avoid serious complications and potentially tragic outcome in such situations.

    Glycemic control alone does not reduce cardiovascular events in patients with type 2 diabetes (T2D), and routine screening of all T2D patients for asymptomatic coronary artery disease (CAD) is not effective for preventing acute cardiac events. We examined the effectiveness of an aggressive screening protocol for asymptomatic CAD in T2D patients with advanced vascular complications.We designed a 3-year cohort study investigating the effectiveness of the aggressive coronary screening for T2D patients with advanced vascular complications and no known coronary events using propensity score adjusted analysis at a national center in Japan. Eligibility criteria included T2D without known coronary events and with any 1 of the following 4 complications: advanced diabetic retinopathy, advanced chronic kidney disease, peripheral artery disease, or cerebrovascular disease. In the aggressive screening group (n = 122), all patients received stress single photon emission computed tomography and those exhibiting myocardial perfusion abnormalities underwent coronary angiography. In the conventional screening group (n = 108), patients were examined for CAD at the discretion of their medical providers. Primary endpoint was composite outcome of cardiovascular death and nonfatal cardiovascular events.Asymptomatic CAD with ≥70% stenosis was detected in 39.3% of patients completing aggressive screening. The proportions achieving revascularization and receiving intensive medical therapy within 90 days after the screening were significantly higher in the aggressive screening group than in the conventional screening group [19.7% vs 0% (P < 0.001) and 48.4% vs 9.3% (P < 0.001), respectively]. The cumulative rate of primary composite outcome was significantly lower in the aggressive screening group according to a propensity score adjusted Cox proportional hazards model (hazard ratio, 0.35; 95% confidence interval, 0.12-0.96; P = 0.04).Aggressive coronary screening for T2D patients

    B lymphocytes and plasma cells are histologically observed in granulomatous periodontal tissues of juvenile periodontitis (JP) patients. Local immune processes may participate in protective or immunopathologic roles in the pathogenesis of this disease. An in vitro explant culture system was utilized to demonstrate the production of immunoglobulins by diseased JP tissues. Immunodiffusion studies using goat anti-human gamma, alpha, or mu chain serum revealed IgG to be the major immunoglobulin present in 92% of the day 1 supernatant fluids (SF) of the 47 JP gingival tissue explant cultures. IgA was present in 15% of the SF; however, no IgM was detected. Staph Protein A isolated 14C-labeled IgG from the SF, when allowed to react with goat anti-human gamma chain serum, formed lines of precipitation. Positive autoradiographs confirmed the biosynthesis of IgG by the explant cultures. The in vitro gingival tissue explant culture system described provides a useful model for the study of localized immunoglobulins produced by diseased tissues of JP patients.

    To investigate the cytokine profile as biomarkers in the gingival crevicular fluid (GCF) of chronic periodontitis (CP) patients with and without obesity, MEDLINE/PubMed, EMBASE, ScienceDirect, and SCOPUS databases were combined with handsearching of articles published from 1977 up to May 2016 using relevant MeSH terms. Meta-analyses were conducted separately for each of the cytokines: resistin, adiponectin, TNF-α, leptin, IL-6, IL-8, and IL-1β. Forest plots were produced reporting standardized mean difference of outcomes and 95% confidence intervals. Eleven studies were included. Three studies showed comparable levels of leptin among obese and nonobese patients with CP. Four studies reported comparable levels of interleukin- (IL-) 6 and resistin whereas five studies reported comparable levels of adiponectin. Two studies reported similar levels of CRP in patients with periodontitis with and without obesity. One study showed higher levels of tumor necrosis factor-alpha in obese patients with CP. One study showed higher levels of IL-1β and IL-8 in obese patients with CP. The level of localized periodontal inflammation may have a greater influence on the GCF proinflammatory biomarker levels as compared to systemic obesity. Whether patients having chronic periodontitis with obesity have elevated proinflammatory GCF biomarkers levels compared to nonobese individuals remains debatable. PMID:27795608

    Background: The success of periodontal therapy depends on the adherence of patients to professional recommendations. The aim of this study was to investigate the influence of a workshop in motivational interviewing (MI) on non-surgical periodontal treatment performed by dental students. Materials and Methods: In the experimental group patients with periodontitis were treated by students trained in MI, while in the control group patients were treated by students who had not been trained in MI. Clinical oral parameters were assessed by a blinded periodontist in addition to the evaluation of psychological questionnaires given before and after the non-surgical periodontal treatment (6 months). Conversations between patients and students were recorded and rated with the Motivational Treatment Integrity Code (MITI-d) by a blinded psychologist. Results: There were 73 patients in the MI group and 99 patients in the control group. The MI group showed significantly higher scores in the MITI-d analysis. Regression analysis showed that there were no significant differences between groups with regard to plaque level, gingival bleeding, pocket depth reduction or bleeding upon probing. However, patients in the MI-group showed significantly higher interdental cleaning self-efficacy than patients in the control group (MI = 19.57 ± 4.7; control = 17.38 ± 6.01; p = 0.016). Conclusion: Teaching MI to dental students resulted in a significant improvement in the self-efficacy of interdental cleaning in patients compared to a control group of non-trained students, but no improvement in other aspects of non-surgical periodontal therapy. The study also showed that an 8-h workshop with supervision significantly improved the MI-compliant conversations of dental students without requiring more conversation time. PMID:26941698

    Identification of predictors of cardiovascular risk can help in the prevention of pathologic episodes and the management of patients at all stages of illness. Here, we investigated the relationships between serum levels of Hsp60 and dyslipidemia in patients with periodontitis by performing a cross-sectional study of 22 patients with mild periodontitis without any prior treatment for it (i.e., drug naïve) and 22 healthy controls, matched for age and body mass index (BMI). All subjects were evaluated for periodontal status, gingival inflammation, and oral hygiene. Levels of circulating Hsp60, C-reactive protein (CRP), and plasma lipids were measured, and small, dense low-density lipoproteins (LDL) were indirectly assessed by determining the triglycerides/high-density lipoproteins (HDL) cholesterol ratio. We also assessed by immunohistochemistry Hsp60 levels in oral mucosa of patients and controls. No difference was found in CRP levels or plasma lipids between the two groups, but subjects with periodontitis showed, in comparison to controls, higher levels of small, dense LDL (p  = 0.0355) and circulating Hsp60 concentrations (p < 0.0001). However, levels of mucosal Hsp60 did not change significantly between groups. Correlation analysis revealed that circulating Hsp60 inversely correlated with HDL-cholesterol (r  = -0.589, p  = 0.0039), and positively with triglycerides (r  = +0.877, p < 0.0001), and small, dense LDL (r  = +0.925, p < 0.0001). Serum Hsp60 significantly correlated with the degree of periodontal disease (r  = +0.403, p  = 0.0434). In brief, untreated patients with mild periodontitis had increased small, dense LDL and serum Hsp60 concentrations, in comparison to age- and BMI-matched controls and both parameters showed a strong positive correlation. Our data indicate that atherogenic dyslipidemia and elevated circulating Hsp60 tend to be linked and associated to periodontal pathology. Thus, the road is open to

    This review examines literature data concerning the bacterial findings in chronic periodontitis depending on pocket depth, and presents the latest published information on the presence of proinflammatory factors in periodontal environment. It has been found that chronic periodontitis affects as much as 80% of the middle-aged population; by comparison, the prevalence of aggressive periodontitis reaches up to 1-1.5%. It is accepted that this social disease is multifactorial in etiology, but the evidence in the literature suggests that the levels of specific Gram-negative organisms in subgingival plaque biofilm play a major role in the initiation and progression of the disease. Of the many bacterial species inhabiting the periodontal environment, three types--Porphyromonas gingivalis (PG), Treponema denticola (TD), Tannerella forsythia (TF)--are strongly associated with the initiation and progression of periodontitis. Microbiological studies suggest that Porphyromonas gingivalis should be considered a major etiologic agent. Currently, Porphyromonas gingivalis is strongly associated with the pathogenesis of chronic periodontitis. On the other hand, the presence of Aggregatibacter actinomycetemeomitans in patients with chronic periodontitis may be related to the severity of the disease and thus modify the therapeutic plan. The increased amount of periodontal pathogens in the subgingival area can activate a cascade of defense mechanisms of the body associated with the production of factors causing inflammation and destruction, which suggests a correlation between the bacterial findings and the body response implemented by enhancing the local cytokine expression. Studies in the literature show that the presence of certain micro-organisms in the periodontal environment is associated to increased levels of proinflammatory cytokines in the gingival fluid and gingival tissue. These levels have been associated with destructive tissues response. There is little evidence in the

    The aim of this study was to investigate the impact of aggression levels on the quality of life (QoL) of epilepsy patients. This study was conducted on 66 volunteer control subjects, who were matched by age and sex to the patient group, which consisted of 66 patients who applied to the Psychiatry and Neurology clinics for outpatient treatment, were aged between 18 years and 65 years, and were diagnosed with epilepsy. A sociodemographic and clinical data form designed by us was distributed among the study participants, along with Buss–Perry Aggression Scale, Beck Anxiety Scale, Beck Depression Scale, and the Quality of Life Scale Short Form (SF-36). Compared with the control group, the patient group displayed higher scores in all subgroups of Buss–Perry Aggression Scale subscales at a statistically significant level (P<0.05). As per the SF-36 questionnaire, physical functioning, physical role disability, general health perception, social functioning, mental health perception, and pain subscales were statistically lower in the patient group (P<0.05). Significant links between Beck Depression Scale and Beck Anxiety Scale levels, as well as some subscales of QoL and aggression levels, were also determined. In conclusion, epilepsy patients experienced impaired QoL compared with the healthy control group and their QoL was further impaired due to increased levels of anxiety, depression, and aggression.

    Background: The aim of this study was to determine if glycosylated hemoglobin is elevated in patients with chronic periodontitis who have not been diagnosed with diabetes and also to compare the HbA1c levels that were obtained with lab and chairside test kit. Materials and Methods: A Case control study was designed. Glycosylated hemoglobin (HbA1c) was assessed using a chairside kit and laboratory method in 70 subjects without diabetes but with chronic periodontitis [having at least 10 teeth (at least one site around each tooth) with probing depth (PD) ≥ 5 mm, bleeding on probing (BOP) ≥15% and clinical attachment level (CAL) ≥ 1 mm] and 70 healthy controls (PD ≤ 4 mm and BOP ≤ 15%). Groups were compared using the t-test and multiple linear regression model analysis. Karl Pearson's correlation coefficient was used to compare the relationship between different variables. Results: In this case control study HbA1c (Lab and Kit) were slightly higher and statistically significant in chronic periodontitis cases than in healthy controls. Conclusion: Chronic periodontitis is associated with a slight elevation in glycosylated hemoglobin (lab and chair side kit) and that the clinical significance of this difference remains to be determined. This preliminary finding is consistent with earlier reports that chronic periodontitis is associated with elevated blood glucose in adults without diabetes and may increase one's risk for type-2 diabetes.

    The association between clinically diagnosed periodontitis, a common chronic oral infection, and metabolic syndrome has been previously reported. The aim of this study was to investigate the association of plasma IgG levels against Aggregatibacter actinomycetemcomitans, Porphyromonas gingivalis, and Prevotella intermedia, C-reactive protein, and periodontal status with metabolic syndrome. Plasma IgG levels and C-reactive protein were measured by enzyme-linked immunosorbent assay, and salivary levels of A. actinomycetemcomitans and P. gingivalis were determined by quantitative real-time polymerase chain reaction. Among 127 individuals aged 35-76 years, 57 participants had metabolic syndrome and severe periodontitis, 25 had metabolic syndrome and an absence of severe periodontitis, 17 healthy individuals had severe periodontitis, and 28 healthy individuals were without severe periodontitis. Patients with metabolic syndrome had reduced humoral immune response to A. actinomycetemcomitans (p = 0.008), regardless of their salivary levels or periodontitis status compared with healthy participants. The IgG antibody response to P. gingivalis, regardless of their salivary levels or participants' health condition, was significantly higher in severe periodontitis patients (p<0.001). Plasma IgG titers for P. intermedia were inconsistent among metabolic syndrome or periodontal participants. Our results indicate that the presence of lower levels of IgG antibodies to A. actinomycetemcomitans (OR = 0.1; 95%CI 0.0-0.7), but not P. gingivalis, a severe periodontitis status (OR = 7.8; 95%CI 1.1-57.0), high C-reactive protein levels (OR = 9.4; 95%CI 1.0-88.2) and body mass index (OR = 3.0; 95%CI 1.7-5.2), are associated with the presence of metabolic syndrome. The role of the decreased IgG antibody response to A. actinomycetemcomitans, increased C-reactive protein levels on the association between periodontal disease and metabolic syndrome in a group of Thai patients is suggested.

    People with type 1 diabetes mellitus manifest a greater burden of both periodontal disease and coronary artery disease (CAD); however, little is known about their interrelation. Coronary artery calcium (CAC) measures subclinical atherosclerosis and predicts major adverse coronary events. The relation between periodontal disease and CAC progression in individuals with type 1 diabetes has not been previously described. We determined the prevalence and progression of CAC in relation to self-reported periodontal disease. Multivariate logistic and tobit regression models were used to examine the relation between periodontal disease duration and CAC progression and whether this relation differs by diabetes status after controlling for age, gender, total and high-density lipoprotein cholesterol, hypertension, smoking, body mass index (BMI), duration of diabetes, and baseline CAC. A total of 473 patients with type 1 diabetes and 548 without diabetes were followed for a mean of 6.1 years. At baseline, the prevalence and duration of periodontal disease did not differ between subjects with and without diabetes (14.5% vs 13.4%, p = 0.60; 6 vs 9 years, p = 0.18). Duration of periodontal disease was not significantly associated with baseline CAC prevalence. In patients with type 1 diabetes, periodontal disease duration was significantly related to CAC progression (p = 0.004) but not in subjects without diabetes (p = 0.63). In conclusion, this study suggests that periodontal disease is an independent predictor of long-term progression of CAC in patients with type 1 diabetes. PMID:26189036

    A sonic electric toothbrush (Sonicare) and an oscillating/rotating electric brush (Braun Oral-B) were compared for efficacy in removing supragingival plaque, reducing gingival inflammation, reducing probing pocket depth (Pd) and improving probing attachment levels (PAL) in a 6-month, single-blind clinical trial. Sixty-six adults with early-moderate periodontitis (5-7 mm Pd in at least two quadrants) entered the study, and 54 completed the entire study. The Sonicare and Braun groups were equally matched for plaque scores, and balanced for age, race and gender. Plaque was scored using the Turesky, Gilmore and Glickman Index. Gingival inflammation was determined by the Papillary Bleeding Score (PBS) of Loesche. Probing depths and attachment levels were determined using a manual North Carolina probe. All measurements were recorded at baseline, 2, 4 and 6 months. The mean overall plaque scores improved in both the Sonicare and the Braun groups at each of the follow-up visits. Interproximal plaque scores also improved in both groups with time, and the mean differential Sonicare post-brushing score was significantly better than the Braun at the 6-month visit (t-test; p = 0.039). Gingival inflammation also decreased in both groups over the 6-month period, but the Sonicare group showed significantly superior PBS scores at 4 months (t-test; p = 0.002) and 6 months (p = 0.005). The percentage reduction in inflammation from baseline at 6 months was 31.9% for Sonicare and 18.1% for Braun. Probing depth scores followed a similar pattern, with the Sonicare showing a mean reduction of 0.84 mm (15.8%) from baseline at 6 months, and Braun showing a 0.39 mm (7.2%) reduction (p = 0.002). In the Sonicare group probing attachment levels improved by 8.6% (MANOVA; p = 0.01), but no PAL improvement was seen in the Braun group. Overall, this study demonstrates that long-term use of these two electric toothbrushes improves periodontal health in adult periodontitis patients, and that the

    Background: The relationship between diabetes and periodontitis has been studied for more than 50 years and is generally agreed that the periodontal disease is more prevalent in diabetic patients compared to nondiabetics. Vascular changes like increased thickness of basement membrane in small vessels has been reported in diabetic patients, but the quantity of blood vessels in gingiva of diabetic patients has not been discussed much. The aim of this study was to compare the number of blood vessels in gingiva between chronic periodontitis (CP) patients, CP with diabetes (type 2), and normal healthy gingiva. Materials and Methods: The study included 75 patients, divided into three groups of 25 patients each-Group I with healthy periodontium (HP), Group II with CP, and Group III with CP with diabetes mellitus (CPDM). Gingival biopsies were obtained from the subjects undergoing crown lengthening procedure for Group I, and in patients with CP and in CPDM biopsies were collected from teeth undergoing extraction. Sections were prepared for immune histochemical staining with CD34. Results: Difference was observed in the average number of blood vessels when compared between HP, CP, and CPDM groups. Statistical significant difference was observed when the HP and CP groups and HP and CPDM groups were compared. Conclusion: The results of the study indicated that the number of blood vessels in gingival connective tissue is significantly higher in CP and CPDM patients. PMID:26015666

    The aims of the present study were to determine the levels of vaspin and omentin-1 in gingival crevicular fluid (GCF) in patients with chronic periodontitis (CP) with and without type 2 diabetes mellitus (T2DM), and to evaluate GCF vaspin and omentin-1 levels after non-surgical periodontal therapy. The study included 60 subjects: 15 systemically and periodontally healthy individuals, 15 periodontally healthy patients with T2DM, 15 systemically healthy patients with CP, and 15 patients with both CP and T2DM. GCF and clinical periodontal parameters were examined at the baseline and 6 weeks after periodontal therapy. Levels of vaspin, omentin-1 and tumor necrosis factor-alpha (TNF-α) were measured by ELISA, and their relative ratios were calculated. GCF vaspin and TNF-α levels were significantly higher in the CP groups than in the periodontally healthy groups (P < 0.008) and decreased after therapy in the former (P < 0.025). GCF omentin-1 levels were significantly lower in the CP groups than in the periodontally healthy groups (P < 0.008) and increased after therapy in the former (P < 0.05). Statistically significant positive correlations were found between the total amount of vaspin and TNF-α, glycated hemoglobin (HbA1c), clinical attachment level and gingival index, whereas the level of omentin-1 was negatively correlated with these parameters in all groups (P < 0.05). We found that non-surgical periodontal therapy influenced the GCF levels of both vaspin and omentin-1 in the CP groups. Our results suggest that the levels of vaspin and omentin-1 in GCF could have potential application as inflammatory markers of diabetes, periodontal disease and treatment outcome.

    Root surface caries is prevalent in patients with both treated and untreated periodontal disease. The major etiologic factor has been identified as microbial plaque. In periodontally treated patients, significantly higher root caries prevalence and incidence have been found in patients with high levels of Streptococcus mutans and Lactobacilli in saliva. Reducing the levels of S. mutans and Lactobacilli in saliva may lower the risk of root caries development. The purpose of this investigation was to determine the effect of an oral enzymatic rinse on the salivary counts of S. mutans and Lactobacilli in periodontally treated patients. Fifteen adult subjects participated in a double-blind, cross-over designed clinical trial. Each subject had previously undergone comprehensive periodontal therapy and had been maintained on a regular program of supportive periodontal therapy. Paraffin-stimulated whole saliva was collected from each participant. Each subject was then randomly given either the enzymatic rinse product or a control rinse and instructed to rinse with one tablespoonful twice a day for 2 weeks, after which saliva samples were taken. After a washout period, salivary samples were again taken, and the subjects received the alternate rinse product. Two weeks later, final salivary samples were taken. The salivary samples were serially diluted and incubated aerobically on selective culture media. S. mutans and Lactobacilli were counted on the basis of colonial morphology. Pretreatment and posttreatment salivary counts of S. mutans and Lactobacilli were analyzed using the Wilcoxon matched-pairs signed-rank test at the 5% level of significance. Analysis of data revealed that neither the test nor the control rinse significantly lowered salivary counts of either species in the sample population.

    Background This pilot study examined whether a novel diabetes screening approach using gingival crevicular blood (GCB) could be used to test for hemoglobin A1c (HbA1c) during the periodontal visit. Methods At a large periodontics clinic, finger stick blood (FSB) samples from 120 patients as well as GCB samples from those patients with adequate bleeding on probing were collected on special blood collection cards and were analyzed for HbA1c levels in a laboratory. The Pearson correlation coefficient was used to measure correlation between FSB and GCB HbA1c values for 75 paired FSB and GCB samples. A Receiver Operator Characteristic Curve (ROC) analysis was performed to determine an optimal GCB HbA1c criterion value for a positive diabetes screen. Results For the 75 paired samples, the Pearson correlation coefficient was .842. The ROC analysis identified a criterion value of 6.3% for the GCB HbA1c test with high sensitivity (.933) and high specificity (.900) corresponding to FSB HbA1c values of 6.5% or greater (in the diabetes range). Using this GCB HbA1c criterion value for 27 additional paired samples in which there was an unidentified component observed to co-elute within the elution window of GCB HbA1c in the laboratory, there was agreement between FSB and GCB values for 24 of the pairs according to whether they were both within, or both outside of the diabetes range. Conclusions Using a criterion value of 6.3%, GCB samples are acceptable for HbA1c testing to screen for diabetes in most persons with bleeding on probing at the GCB collection site. PMID:22087806

    Objective Identify aggressive onset multiple sclerosis (AOMS) and describe its clinical course. Methods AOMS patients were identified from a multiple sclerosis (MS) database based on a set of criteria. The subsequent clinical course of AOMS patients was then reviewed with the goal of potentially identifying the best approaches to manage these patients. Results Fifty-eight of 783 (7.4%) patients in the MS database met the criteria for AOMS, and 43 patients who had complete data for the duration of their follow-up were included in the subsequent analysis. The mean duration of the follow-up was 54 months. Thirty-five patients (81%) were started on a conventional first-line agent (injectable therapies for MS). Only two of these 35 patients (5.7%) had no evidence of disease activity. Twenty-two of 35 patients suffering from refractory disease were switched to a more aggressive treatment (natalizumab, rituximab, alemtuzumab, cyclophosphamide). Eight patients were started on aggressive treatment as their initial therapy, and seven of these eight (87.5%) patients showed no evidence of disease activity. Conclusion With recognition of the crucial significance of early optimal treatment during the potential window of opportunity for best long-term outcomes, we describe AOMS within 1 year of disease onset and discuss possible treatment considerations for these patients.

    This study was to evaluate clinical and microbiological effectiveness of photodynamic therapy (PDT) in the treatment of periodontal disease in kidney-transplanted patients. Eight kidney transplanted patients treated at Paulista University were arranged in two groups: SRP performed scaling and root planning by ultrasound; SRP+PDT- in the same patient, which was held to PDT in the opposite quadrant, with 0.01% methylene blue and red laser gallium aluminum arsenide, wavelength 660 nm, power 100 mW. There was reduction in probing pocket depth after 45 days and 3 months regardless the group examined; plaque and bleeding index showed improvement over time, regardless the technique used, and bleeding index in the SRP+PDT group was lower when compared with the baseline the other times. There was no difference in the frequency of pathogens. Photodynamic therapy may be an option for treatment of periodontal disease in renal-transplanted patients and its effectiveness is similar to conventional therapy.

    Objectives: Several studies have focused on the relationship among serotype distribution, ethnical status and geographic populations, and periodontal conditions. Studies that have investigated the prevalence and the distribution of A. actinomycetemcomitans serotypes and the relation between the different serotypes of the bacterium and periodontal status were reviewed. Material and Methods: A systematic literature search for publications regarding the distribution of A. actinomycetemcomitans serotypes in subgingival samples of periodontitis patients and periodontally healthy subjects by employing polymerase chain reaction (PCR) was conducted. Results: From the 85 studies identified in the first analysis, only 12 met all inclusion and exclusion criteria. Clinical isolates from diverse geographic populations with different periodontal conditions were evaluated. Serotypes a, b and c were largely found, and serotype c was the most prevalent. They were isolated from various periodontal conditions, including aggressive periodontitis. Conclusions: The available literature suggests that serotypes a, b, and c are globally dominant, serotypes d and e are rare, and the prevalence of the most recently identified serotype fis still unknown. It is widely accepted that distribution patterns of A. actinomycetemcomitans vary among subjects of different ethnicity and geographic regions. The correlation of different serotypes with various periodontal conditions remains unclear. Key words:Aggregatibacter actinomycetemcomitans, serotypes, periodontal disease, prevalence. PMID:24316700

    Periodontal disease has been associated with an increased risk of cardiovascular events. The purpose of our study was to investigate whether a correlation between periodontitis and chronic heart failure exists, as well as the nature of the underlying cause. We enrolled 71 patients (mean age, 54 ± 13 yr; 56 men) who had stable chronic heart failure; all underwent complete cardiologic and dental evaluations. The periodontal screening index was used to quantify the degree of periodontal disease. We compared the findings to those in the general population with use of data from the 4th German Dental Health Survey. Gingivitis, moderate periodontitis, and severe periodontitis were present in 17 (24%), 17 (24%), and 37 (52%) patients, respectively. Severe periodontitis was more prevalent among chronic heart failure patients than in the general population. In contrast, moderate periodontitis was more prevalent in the general population (P <0.00001). The severity of periodontal disease was not associated with the cause of chronic heart failure or the severity of heart failure symptoms. Six-minute walking distance was the only independent predictor of severe periodontitis. Periodontal disease is highly prevalent in chronic heart failure patients regardless of the cause of heart failure. Prospective trials are warranted to clarify the causal relationship between both diseases. PMID:27547136

    Aggressive patients often target psychiatrists and psychiatric residents, yet most clinicians are insufficiently trained in violence risk assessment and management. Consequently, many clinicians are reluctant to diagnose and treat aggressive and assaultive features in psychiatric patients and instead focus attention on other axis I mental disorders with proven pharmacological treatment in the hope that this approach will reduce the aggressive behavior. Unclear or nonexistent reporting policies or feelings of self-blame may impede clinicians from reporting assaults, thus limiting our knowledge of the impact of, and best response to, aggression in psychiatric patients. The authors pre-sent the case of a young adult inpatient with a long history of antisocial and assaultive behavior who struck and injured a psychiatric resident. With this case in mind, the authors discuss the diagnostic complexities related to violent patients, the importance of assessing violence risk when initially evaluating a patient, and the relevance of risk assessment for treatment considerations and future management. This report illustrates common deficiencies in the prevention of violence on inpatient psychiatric units and in the reporting and response to an assault, and has implications for residency and clinician training.

    The application of laser as a monotherapy has been shown to reduce probing pocket depths and increase clinical attachment levels after treatment of patients suffering from chronic periodontitis. Its controversial use as an adjunct to scaling and root planing (SRP) is discussed. The present study aimed to evaluate the efficacy of adjunctive Er, Cr:YSGG laser application following conventional SRP. A total of 30 patients with chronic periodontitis were enrolled in the study. The quadrants of each patient were allocated to either SRP or SRP + laser. A total of 3,654 sites with pocket depths ≥ 4 mm were treated and evaluated at 6 weeks and 6 months postoperatively with respect to attachment gain. Both therapies resulted in improved probing pocket depths and clinical attachment levels. The adjunctive application of Er, Cr:YSGG laser following SRP did not improve probing pocket depth or attachment level compared with SRP alone. PMID:27560676

    Background: The present study is designed to evaluate the clinical effects of pulsated subgingival irrigation with tetracycline and spiramycin. Materials and Methods: Ten patient diagnosed chronic periodontitis were included in the present study. Each patient is assigned to be irrigated with saline (placebo) (Group A), tetracycline HCl at 0.5% concentration (Group B), and 0.5% spiramycin (Group C). Scaling and root planing (SC/RP) was recorded as Group D. Plaque index, gingival index, gingival bleeding index, probing pocket depth were assessed on pre-irrigation (day 0), and at days 7, 14, 21, 28, and 35 day. Results: The results showed that subgingival irrigation with 0.5% tetracycline and spiramycin produced a significant reduction in clinical parameters compared to the control, while SC/RP was showed better improvement. Conclusion: The result of this study suggested that subgingival irrigation of tetracycline and spiramycin play a beneficial role in the management of chronic periodontitis patients. PMID:26229381

    Objective: Single nucleotide polymorphisms (SNPs) in the promoter region of interleukin (IL)-10 gene, which codes for the anti-inflammatory cytokine IL-10, have been associated with its level of production in chronic periodontitis. The prevalence of promoter SNP genotypes is known in other populations with chronic periodontitis, while its association in the Indian population is not known. Hence, the present study was designed to investigate the prevalence of IL-10 promoter polymorphism in a racially defined group of Indians with severe chronic periodontitis as the Indian population is known to be genetically diverse. Materials and Methods: Genomic deoxyribonucleic acid was extracted from 46 nonsmoking patients with severe chronic periodontitis and 45 subjects with healthy periodontium. A SNP locus at −1087 of IL-10 was chosen, as this locus has been frequently associated with chronic periodontitis in other population. Genotyping was carried out using allele-specific polymerase chain reaction (AS-PCR), and the frequencies of genotype were analyzed between the groups. Results: The distribution of genotype and allele frequencies showed significant differences between the study groups. The prevalence of genotype AA alleles at −1087 locus of IL-10 was significantly higher in severe chronic periodontitis patients compared to the healthy controls (P = 0.05). Conclusion: The study has identified a positive association between the occurrence of AA allele at −1087 locus of IL-10 gene and severe chronic periodontitis in nonsmoking patients. PMID:26430368

    Background: Type 2 diabetes mellitus (T2DM) and periodontitis are inflammatory conditions with a bidirectional association. This pilot study aimed to evaluate whether T2DM and glycemic control interfere in inflammatory markers profiles in gingival crevicular fluid (GCF) in periodontitis patients. Materials and Methods: Fourteen diabetic periodontitis patients were enrolled in this study, seven with adequate glycemic control (glycated hemoglobin [HbA1c] <8.0%) (DMA + P) and seven with inadequate control (HbA1c ≥8.0%) (DMI + P). Seven chronic periodontitis patients without diabetes formed the control group (P). GCF was obtained from diseased sites (probing depth >6 mm) of an entirely hemiarch, pooled and cytokines levels determined using multiplex beads immunoassay. Clinical periodontal parameters were analyzed by Mann-Whitney test and levels of cytokines by Kruskal-Wallis and Dunn's multiple comparison tests with confidence level of 95% (P < 0.05). Results: Cytokines profile of GCF obtained from deep periodontal pockets presented high levels of inflammatory cytokines, and there were no statistical differences between levels of interleukin-6 (IL-6), IL-8 and tumor necrosis factor-α according to presence of diabetes or percentage of HbA1c among the groups, despite groups with T2DM and periodontitis exhibit higher levels of PD. Conclusion: Within the limitations of this study, inflammatory mediators in GCF are dependent to the local response and do not correlate with the diabetic status. PMID:26604959

    Cystic fibrosis (CF) is the most frequent lethal genetic disease in the Caucasian population. Lung destruction is the principal cause of death by chronic Pseudomonas aeruginosa colonization. There is a high prevalence of oropharyngeal anaerobic bacteria in sputum of CF patients. This study was carried out due to the lack of results comparing subgingival periodontal pathogenic bacteria between the oral cavity and lungs in patients with CF in relation with P. aeruginosa presence. Our first goal was to detect P. aeruginosa in oral and sputum samples by culture and molecular methods and to determine clonality of isolates. In addition, subgingival periodontal anaerobic bacteria were searched for in sputum. A cross-sectional pilot case-control study was conducted in the CF Reference Center in Roscoff, France. Ten CF patients with a ΔF508 homozygous mutation (5 chronically colonized [CC] and 5 not colonized [NC]) were enrolled. P. aeruginosa was detected in saliva, sputum, and subgingival plaque samples by real-time quantitative PCR (qPCR). Subsequently, periodontal bacteria were also detected and quantified in subgingival plaque and sputum samples by qPCR. In CC patients, P. aeruginosa was recovered in saliva and subgingival plaque samples. Sixteen P. aeruginosa strains were isolated in saliva and sputum from this group and compared by pulsed-field gel electrophoresis (PFGE). Subgingival periodontal anaerobic bacteria were found in sputum samples. A lower diversity of these species was recovered in the CC patients than in the NC patients. The presence of the same P. aeruginosa clonal types in saliva and sputum samples underlines that the oral cavity is a possible reservoir for lung infection. PMID:25854483

    The Receptor activator of nuclear factor-kappa B ligand (RANKL)/RANK/Osteoprotegerine (OPG) system has been proposed as essential for osteoclast biology and identified as key part in regulating the physiology and pathology of the skeletal system. The study of the RANKL/RANK/OPG system has increased the understanding of the mechanisms involved in the bone remodeling process, especially in postmenopausal osteoporosis and periodontal disease. Bisphosphonates have become the mainstay of the treatment and prevention of post-menopausal osteoporosis. They inhibit the formation and dissolution of calcium phosphate crystals in bone and also osteoclasts, thus reducing bone turnover.Current investigations relate osteoporosis with the appearance and progression of periodontal disease. Although the etiology of both is different, the bone loss present in both shares several characteristics. Thus, therapy used for osteoporosis can be considered of value in the treatment of periodontal disease. The aim of this study was to evaluate the levels of RANKL, OPG and their relationship in gingival crevicular fluid (GCF) in patients with periodontal disease and postmenopausal osteoporosis/ osteopenia in relation to consumption of bisphosphonates. We studied 66 periodontal active sites obtained from 17 post- menopausal women patients aged between 45-70 years old with osteoporosis/osteopenia and periodontal disease. GCF samples were collected using sterile filter paper strips. To determine the concentration of RANKL and OPG, a commercial ELISA assay was used. The values of RANKL, OPG and their ratio (RANKL/ OPG) were compared with Mann-Whitney U Test. The values of RANKL, OPG and their ratio obtained in patients with osteoporosis/osteopenia and periodontal disease with or without bisphosphonates treatment showed no differences. Bisphosphonates do not alter the concentration of RANKL and OPG and their ratio in the GCF of patients with osteoporosis/ osteopenia and periodontal disease

    An association between periodontal disease and rheumatoid arthritis is believed to exist. Most investigations into a possible relationship have been case-control studies with relatively low sample sizes. The advent of very large clinical repositories has created new opportunities for data-driven research. We conducted a retrospective cohort study to measure the association between periodontal disease and rheumatoid arthritis in a population of 25 million patients. We demonstrated that subjects with periodontal disease were roughly 1.4 times more likely to have rheumatoid arthritis. These results compare favorably with those of previous studies on smaller cohorts. Additional work is needed to identify the mechanisms behind this association and to determine if aggressive treatment of periodontal disease can alter the course of rheumatoid arthritis.

    Abstract Background: Many primary and secondary studies reported the association between Toll-like receptor 4 (TLR4) polymorphism and periodontitis susceptibility, which mainly focused on TLR4–299A>G or TLR4–399C>T of Caucasian, however, these studies had different conclusions. The aim of this study was to reassess relative studies about TLR4 polymorphism and periodontitis susceptibility, and update meta-analysis. Methods: We searched the electronic database including CNKI (Chinese National Knowledge Infrastructure), PubMed, Embase, and hand searched relative studies until January 4, 2016. Two authors selected studies according to inclusion and exclusion criteria, assessed studies using Newcastle-Ottawa Scale case control study (NOS), and calculated the combined effect size using STATA software, version 12.0. Results: This meta-analysis included 18 studies, containing 2453 healthy participants and 2987 patients with chronic periodontitis (CP) and 462 patients with aggressive periodontitis (AP). There was a significance between TLR4C>G (rs7873784) allele and CP in Asian, and its recessive model was also significant (for C vs G: odds ratio [OR] = 0.72, 95% confidence interval [CI] = 0.54–0.95, I2 = 0%; for CC + CG vs GG: OR = 0.66, 95% CI = 0.49–0.89, I2 = 0%). However, we did not detect any significant relevance between other TLR4 polymorphism and periodontitis susceptibility in overall and subgroup analyses. The sensitive analysis showed that dropping any single studies did not affect the pooled-analysis results. Publication bias was not detected. Conclusions: The meta-analysis found association between TLR4C>G (rs7873784) allele and CP in Asian and it may passed on to offsprings in the form of recessiveness. However, further studies about the association between TLR4C>G (rs7873784) and CP is warranted to confirm. PMID:27603404

    The orthodontist is in fact a periodontal-therapist since his aim is to move the teeth with and through the periodontal tissues. It is most important for the orthodontist to be able to determine at the initial clinical examination what are the various periodontal risk factors. When the pathology is obvious with inflammation, periodontal pockets, gingival hyperplasia, edema of the papillae, gingival recessions, the need for periodontal treatment is manifest. But many times, the periodontal evaluation is complicated by the presence of slight variations of the quality of the marginal tissue that represent a risk of developing periodontal defects during the orthodontic treatment. The aim of this presentation is to put forward the importance of the periodontal evaluation during the initial examination of the patient so that, if necessary, an adequate periodontal therapy can be initiated to stabilize the periodontal tissues and thus improves the esthetical outcome.

    We investigated the outcome of conventional periodontal treatment in mouth breathing patients with chronic periodontitis, and compared the efficacy of applying salivary substitute to the anterior sextants as an adjunct to conventional treatment in such patients. In this randomized, investigator-blind, clinical study involving parallel groups, 40 mouth breathing patients were divided into two groups: a control group (CG, n = 20) comprising patients who received scaling and root planing (SRP), and a test group (TG, n = 20) who received salivary substitute as an adjunct to SRP for treatment of chronic periodontitis. The patients were followed up at various time intervals, and improvement of the gingival index (GI) was examined as the primary outcome. Student's t-test, repeated-measures ANOVA and Mann-Whitney U test were applied for statistical analysis. Although periodontal parameters were improved in both groups after 8 weeks of follow-up, the test group showed better improvement in terms of GI and percentage bleeding on probing. Within the limits of this study, our results suggest that the use of salivary substitute has a beneficial adjunctive effect for improvement of periodontal parameters in mouth breathing patients with chronic periodontitis.

    The microbiocenosis of periodontal recesses was studied and an assessment of the innate immunity mechanisms, as well as profiles of inflammatory cytokines were carried out in 114 people of middle, elderly and senile age with chronic generalized periodontitis (CGP). It was found that periodontal recesses mikrobiocenosis of patients with CGP of various ages was mainly presented by conditionally pathogenic bacterial and fungal microflora. There were identified the inefficient mechanisms of immune inflammation in case of conditionally pathogenic microflora, the reduction of neutrophils functional properties, and the increasing part of destructed phagocytazing neutrophils in patients of elderly and senile age. The immunosuppression in patients of elderly and senile age appears in insufficient production of IL-1beta, IL-8, resulting in reduced activity of phagocytosis mechanisms and lymphoid cells functional activity. Thus, the differences in etiopatogenetic microflora, immune homeostasis status in patients with CGP in middle, elderly and senile age, complexity in the application of antibacterial drugs require the development of new criteria for the selection of antibacterial drugs.

    2012-01-01

    Background Periodontal disease is thought to arise from the interaction of various factors, including the susceptibility of the host, the presence of pathogenic organisms, and the absence of beneficial species. The genetic factors may play a significant role in the risk of periodontal diseases. Cytokines initiate, mediate and control immune and inflammatory responses. The aim of this study is to compare genotypes and soluble protein of pro and anti-inflammatory cytokines (IL-1α, IL-1β, IL-6, IFN-γ, IL-10, TNF-α and IL-4) in subjects with or free of chronic periodontitis. Methods A total of 1,290 Chinese subjects were recruited to this clinical trial: 850 periodontally healthy controls and 440 periodontal patients. All subjects were free of systemic diseases. Oral examinations were performed, and the following parameters were recorded for each subject: supragingival/subgingival calculus, gingival recession, bleeding on probing (BOP), probing depth (PD), clinical attachment loss (CAL), gingival recession and tooth mobility. The peripheral blood samples were collected for genetic and enzyme linked immunosorbent assay (ELISA) analysis. Restriction enzymes were used for digestion of amplified fragments of IL-1α, IL-1β, IL-6, IFN-γ, IL-10, TNF-α and IL-4. Results The protein expressions of patient and control samples for IL-1α, IL-1β, IL-6, TNF-α, IFN-γ, IL-10, and IL-4 measured by ELISA confirmed a statistically significant difference (p < 0.001). The digestion of fragments of various genes showed that the pro-inflammatory cytokines IL-1α and TNF-α, and the anti-inflammatory cytokines IL-4 and IL-10 demonstrated a correlation with chronic inflammation in patients (X2: p < 0.001). The remaining genes investigated in patients and healthy subjects (IL-1β, IL-6, IFN-γ and IL-10) did not show any significant difference. Conclusions The cytokine gene polymorphisms may be used as a marker for periodontitis susceptibility, clinical behaviour and severity. This

    Kostmann syndrome is a rare, congenital immunological disorder caused by a mutation of the hematopoietic cell-specific LYN substrate 1-associated protein X1. These patients pose a unique challenge to the dental practitioner due to the severe oral infections that are often seen in this population. The patient described in this report is a 16-year-old female with Kostmann syndrome-associated periodontitis. The treatment consisted of scaling and root planing performed in conjunction with subgingival irrigation with povidone-iodine solution. This report details how Kostmann syndrome-associated periodontitis can be successfully treated and maintained long-term, using non-surgical treatment modalities and local antimicrobial therapy.

    Background: C-reactive protein (CRP) - a prototypic marker of inflammation has been shown to be elevated in chronic periodontitis (CP) and also been shown to predict cardiovascular events. Increased carotid intima media thickness (CIMT) has been recently recognized as surrogate marker for atherosclerosis. In this context, we studied to correlate between CIMT and CRP in CP and to know whether CRP predicts the cardiovascular risk in CP. Materials and Methods: The study consisted of 30 systemically healthy subjects aged over 40 years - 15 subjects with CP as cases and 15 subjects with no periodontitis as controls. All subjects were subjected to measurement of CRP levels and CIMT in addition to detailed periodontal evaluation. Quantitative determination of CRP was done by turbidimetric immunoassay. IMT of the common carotid arteries was estimated bilaterally using B-mode ultrasound at 6 sites. Positive CRP was defined as more than 10 mg/l. Results: Mean CRP levels were significantly higher in subjects with CP (19.58 ± 17.03), then in non CP (NCP) (5.54 ± 1.63, P < 0.004). Mean CIMT value was significantly higher in subjects with CP (1.09 ± 0.45) than in NCP (0.57 ± 0.06, P < 0.001) and all periodontal indices correlated well with CIMT. Further, there was significant correlation between CRP and increased CIMT in subjects with CP (r = 0.863, P < 0.001). Conclusions: The present study indicates CRP as a possible underlying pathway in the association between periodontal disease and the observed CIMT. CRP can be used as a risk predictor for atherosclerosis in patients with CP. PMID:25214732

    Bacteraemia of oral origin may result in infective endocarditis in susceptible individuals. The aim of this pilot study was to investigate the occurrence of bacteraemia due to periodontal probing. Thirty patients (15 male, 15 female; mean age 42.7 years) with untreated periodontitis were investigated. All were free of significant medical disorders and none had taken antibiotics in the previous month. Prior to and immediately following periodontal probing, 20 mL of venous blood were obtained from each patient and inoculated into aerobic and anaerobic blood culture bottles and incubated. Negative bottles were monitored continuously for three weeks before being discarded. Periodontal probing consisted of measuring pockets at six points around each tooth and recording the presence or absence of bleeding. A positive bacteraemia was recorded for three of the patients prior to probing. One patient exhibited Prevotella species whilst two exhibited skin commensals. Following probing, 13 patients (43 per cent) exhibited bacteraemia of oral origin. Viridans streptococci were the most common isolates (45 per cent). No significant correlations were found between bacteraemia and the severity of periodontitis or extent of bleeding on probing. The results indicate that periodontal probing can cause bacteraemia in patients with periodontitis. It would be advisable for patients considered at risk of developing infective endocarditis to receive antibiotic prophylaxis for periodontal probing if they have radiographic evidence of periodontitis.

    Aim To evaluate the effects of systemic antibiotics in combination with scaling and root planing (SRP) on periodontal parameters, tooth loss and oral health-related quality of life in diabetes patients. Materials and Methods Two independent reviewers screened for controlled clinical trials with at least 6-month follow-up in six electronic databases, registers of clinical trials, meeting abstracts and four major dental journals. After duplicates removal, electronic and hand searches yielded 1,878 records; 18 full-text articles were independently read by two reviewers. To evaluate the additional effect of antibiotic usage, pooled weighted mean differences and 95% confidence intervals were calculated using a fixed effects model. Results Five studies met the inclusion criteria, four of which were included in meta-analyses. The meta-analyses showed a significant effect favouring SRP plus antibiotic for reductions in mean probing depth (PD) (-0.22 mm [-0.34, -0.11]) and mean percentage of bleeding on probing (BoP) (4% [-7, -1]). There was no significant effect for clinical attachment level gain and plaque index reduction. No study reported on tooth loss and oral health-related quality of life. Conclusion Adjunctive systemic antibiotic use in diabetic patients provides a small additional benefit in terms of reductions in mean PD and mean percentage of BoP.

    Carriage of polymorphic alleles of genes of cytokines-interleukines IL-1β, IL-1RN, TNFα, IL-4 can be a specific feature of chronic periodontitis patients. Genetic tests can be used to predict the course of the disease at its early manifestations. Objective: To establish the relationship of clinical manifestations of periodontal disease, inflammatory cytokines gene polymorphism and systemic levels of cytokine production. Periodontal tissue assessment and cone-beam computed tomography (CBCT) were performed in 150 periodontitis patients. A molecular--genetic testing for the presence of polymorphic alleles of genes IL-1β -511 C>T and +3953 C>T, IL-1RN (VNTR intron 2), IL-4 (VNTR intron 3), TNFα-308 G>A; content determined IL-1β, TNFα, IL-4 in peripheral blood was carried out in 150 patients with periodontitis and 150 healthy donors. Based on the analysis of the speed and nature of the supporting bone resorption and clinical manifestations patients are divided in "aggressive", "moderately progressive" and "slowly progressive" periodontits course groups. Disease severity was associated with distribution of genotypes and alleles of polymorphic genes cytokine IL-1RN (VNTR intron 2), TNFα-308 G>A and IL-4 (VNTR intron 3); haplotype IL-1β-511 TIL-1β +3953 T/IL-1RN 2R. There was no statistically significant difference in systemic level of IL-1β, TNFα and IL-4 between periodontitis groups but the donor level of cytokines was 2-4 times less.

    Objective To compare outcomes at 36 months in patients newly diagnosed with juvenile dermatomyositis (DM) treated with aggressive versus standard therapy. Methods At diagnosis, 139 untreated juvenile DM patients were given aggressive therapy (intravenous methylprednisolone or oral prednisone 5–30 mg/kg/day; n = 76) or standard therapy (1–2 mg/kg/day; n = 63) by the treating physician. Aggressive therapy patients were more ill at diagnosis. Matching was based on the propensity for aggressive therapy because propensity scoring can reduce confounding by indication. Logistic regression of the matched data determined predictors of outcomes, controlling for clinical confounders and propensity score. Outcomes comprised Disease Activity Score (DAS) for skin and muscle, range of motion (ROM), and calcification. Results Sex, race, and age were similar between groups, and initial DAS weakness and ROM significantly predicted the therapy chosen. Based on propensity scores, 42 patients from each group were well matched. In the matched pairs, there were no significant differences in outcomes. Methotrexate use (odds ratio [OR] 3.6, 95% confidence interval [95% CI] 1.15–11.5) and duration of untreated disease (OR 1.2, 95% CI 1–1.38) were associated with ROM loss, hydroxychloroquine use (OR 11.2, 95% CI 3.7–33) and calcification (OR 6.8, 95% CI 1.8–25.4) with persistent rash, abnormal baseline lactate dehydrogenase (OR 11.2, 95% CI 1.4–92) and age at onset (OR 1.3, 95% CI 1–1.4) with weakness, and duration of untreated disease (OR 1.2, 95% CI 1–1.39) with calcification. Conclusion Using a retrospective, nonrandomized design with propensity score matching, there was little difference in efficacy outcomes between aggressive and standard therapy; however, the sickest patients were treated with aggressive therapy and were not included in the matched analysis. Comprehensive clinical studies are needed to determine therapeutic pathways to the best outcome. PMID:18576304

    Inflammatory myofibroblastic tumors (IMTs) are rare. IMTs of the head and neck occur in all age groups, from neonates to old age, with the highest incidence occurring in childhood and early adulthood. An IMT has been defined as a histologically distinctive lesion of uncertain behavior. This article describes an unusual case of IMT mimicking apical periodontitis in the mandible of a 42-year-old man. At first presentation, the patient showed spontaneous pain and percussion pain at teeth #28 to 30, which continued after initial endodontic treatment. Panoramic radiography revealed a radiolucent lesion at the site. Cone-beam computed tomographic imaging showed osteolytic lesions, suggesting an aggressive neoplasm requiring incisional biopsy. Histopathological examination indicated an IMT. The lesion was removed en bloc under general anesthesia, and the patient manifested no clinical evidence of recurrence for 24 months. Lesions of nonendodontic origin should be included in the differential diagnosis of apical periodontitis. Every available diagnostic tool should be used to confirm the diagnosis. Cone-beam computed tomographic imaging is very helpful for differential diagnosis in IMTs mimicking apical periodontitis. PMID:26602450

    The loss of periodontal structure causes an esthetic problem for many patients, especially when the esthetic zone is compromised. Among the various types of solutions is the use of composite resins. While this procedure is not aggressive towards tooth structure, it does require the clinician to have a precise technique, and demands strict longterm maintenance. 1 Another way of treating the compromised teeth is with porcelain veneers. This procedure is especially difficult, however, if carried out on periodontal teeth, as it requires preparation along the roots. 2 The intention of the hybrid technique described in this article is to combine both of these procedures in order to obtain a less aggressive treatment with precise management of the soft tissue and an adequate esthetic outcome. The hybrid technique consists of enlarging the root portion of the teeth with composite resin to obtain a less aggressive tooth preparation, and thereafter placing porcelain veneers.

    As implant therapy becomes more commonplace in daily practice, preservation and preparation of edentulous sites are key. Many times, however, implant therapy may not be considered at the time of tooth extraction and additional measures are not taken to conserve the edentulous site. While the healing process in extraction sockets has been well investigated and bone fill can be expected, there are cases where even when clinicians perform thorough debridement of the sockets, connective tissue infiltration into the socket can occur. This phenomenon, known as “erratic healing,” may be associated with factors that lead to peri-implant disease and should be appropriately managed and treated prior to surgical implant placement. This case report describes the successful management of an erratic healing extraction socket in a 62-year-old Caucasian male patient with chronic periodontitis and the outcomes of an evidence-based treatment protocol performed prior to implant therapy. Careful preoperative analysis and cone beam computed tomography imaging can help detect signs of impaired healing in future implant sites and prevent surgical complications. PMID:27807485

    This study evaluated the use of tricalcium phosphate (TCP) ceramic implant material in periodontal osseous defects. Thirteen defects in two patients were treated with mucoperiosteal flaps and placement of TCP. The defects were evaluated clinically and radiographically utilizing standardized probe placement and radiographic technique. Clinically, there was a mean probing pocket reduction of 4.5 mm as a result of a mean gain of clinical probing attachment level of 2.0 mm and a mean gingival recession of 2.5 mm. Radiographically, there was a mean "fill" of 1.8 mm. Six teeth were removed by block biopsy for histologic analysis, three at 3 months, one at 6 months and two a 9 months. The TCP particles were well tolerated and encapsulated by fibrous connective tissue, but the particles did not stimulate new bone growth. The junctional epithelium ended 1.62 mm coronal to the apical extent of a reference notch placed at the base of the defect. Although new cementum was observed, there was limited evidence of new attachment. PMID:3856005

    The association between periodontitis and some of the problems with pregnancy such as premature delivery, low weight at birth, and preeclampsia (PE) has been suggested. Nevertheless, epidemiological data have shown contradictory data, mainly due to differences in clinical parameters of periodontitis assessment. Furthermore, differences in microbial composition and immune response between aggressive and chronic periodontitis are not addressed by these epidemiological studies. We aimed to review the current data on the association between some of these problems with pregnancy and periodontitis, and the mechanisms underlying this association. Shifts in the microbial composition of the subgingival biofilm may occur during pregnancy, leading to a potentially more hazardous microbial community. Pregnancy is characterized by physiological immune tolerance. However, the infection leads to a shift in maternal immune response to a pathogenic pro-inflammatory response, with production of inflammatory cytokines and toxic products. In women with periodontitis, the infected periodontal tissues may act as reservoirs of bacteria and their products that can disseminate to the fetus-placenta unit. In severe periodontitis patients, the infection agents and their products are able to activate inflammatory signaling pathways locally and in extra-oral sites, including the placenta-fetal unit, which may not only induce preterm labor but also lead to PE and restrict intrauterine growth. Despite these evidences, the effectiveness of periodontal treatment in preventing gestational complications was still not established since it may be influenced by several factors such as severity of disease, composition of microbial community, treatment strategy, and period of treatment throughout pregnancy. This lack of scientific evidence does not exclude the need to control infection and inflammation in periodontitis patients during pregnancy, and treatment protocols should be validated.

    The ecological diversity of the periodontal microenvironment may provide suitable conditions for the colonization of species not usually considered members of the oral microbiota. In this investigation, we aimed to determine the prevalence and levels of pathogenic species of medical relevance in the microbiota of individuals with distinct periodontal clinical status. Subgingival biofilm was obtained from patients with periodontal health (H, n = 81), gingivitis (G, n = 55), generalized aggressive (AgP, n = 36) or chronic periodontitis (CP, n = 98), and analyzed for 39 microbial taxa using a checkerboard DNA-DNA hybridization technique. Microbial differences among groups, as well as associations between clinical and microbiological parameters were sought by non-parametric and univariate correlation tests. Neisseria spp., Peptostreptococus anaerobius, Candida albicans, enterobacteria, Pseudomonas aeruginosa, Eubacterium saphenum, Clostridium difficile and Olsenella uli were detected in high mean prevalence and counts in the subgingival microbiota of the study population. Species that were more related to periodontal inflammation and tissue destruction at the patient and site levels included enterobacteria, C. albicans, Neisseria spp., P. aeruginosa, O. uli, Hafnia alvei, Serratia marcescens and Filifactor alocis (p < 0.05). In contrast, Fusobacterium necrophorum, Lactobacillus acidophilus, Staphylococcus aureus and Streptococcus pneumoniae were associated with periodontal health (p < 0.05). Pathogenic species of medical importance may be detected in high prevalence and levels in the periodontal microbiota. Regardless of their role in periodontal health or disease, the periodontal biofilm may be a source for dissemination and development of systemic infections by these pathogenic microorganisms.

    The association between clinically diagnosed periodontitis, a common chronic oral infection, and metabolic syndrome has been previously reported. The aim of this study was to investigate the association of plasma IgG levels against Aggregatibacter actinomycetemcomitans, Porphyromonas gingivalis, and Prevotella intermedia, C-reactive protein, and periodontal status with metabolic syndrome. Plasma IgG levels and C-reactive protein were measured by enzyme-linked immunosorbent assay, and salivary levels of A. actinomycetemcomitans and P. gingivalis were determined by quantitative real-time polymerase chain reaction. Among 127 individuals aged 35–76 years, 57 participants had metabolic syndrome and severe periodontitis, 25 had metabolic syndrome and an absence of severe periodontitis, 17 healthy individuals had severe periodontitis, and 28 healthy individuals were without severe periodontitis. Patients with metabolic syndrome had reduced humoral immune response to A. actinomycetemcomitans (p = 0.008), regardless of their salivary levels or periodontitis status compared with healthy participants. The IgG antibody response to P. gingivalis, regardless of their salivary levels or participants’ health condition, was significantly higher in severe periodontitis patients (p<0.001). Plasma IgG titers for P. intermedia were inconsistent among metabolic syndrome or periodontal participants. Our results indicate that the presence of lower levels of IgG antibodies to A. actinomycetemcomitans (OR = 0.1; 95%CI 0.0–0.7), but not P. gingivalis, a severe periodontitis status (OR = 7.8; 95%CI 1.1–57.0), high C-reactive protein levels (OR = 9.4; 95%CI 1.0–88.2) and body mass index (OR = 3.0; 95%CI 1.7–5.2), are associated with the presence of metabolic syndrome. The role of the decreased IgG antibody response to A. actinomycetemcomitans, increased C-reactive protein levels on the association between periodontal disease and metabolic syndrome in a group of Thai patients is

    The purpose of this report was to describe the management of an eight-year-old Bulgarian male with Down syndrome presenting with periodontitis as a manifestation of systemic disease in the early mixed dentition. Treatment involved full-mouth mechanical debridement and extraction of hopeless teeth under general anesthesia followed by systemic antibiotics and chemical adjunctive therapy. Microbial culture and sensitivity testing aided in diagnosis and guided treatment decisions. This case report demonstrates a multidisciplinary approach in the management of aggressive periodontal disease in an internationally adopted pediatric patient with special health care needs.

    Background Several studies have shown an association between oral diseases and chronic kidney disease (CKD), and regular oral care may be an important strategy for reducing the burden of CKD. The objective of this study was therefore to evaluate the association between dental and periodontal diseases in Thai patients with various stages of CKD. Methods This was designed as a cross-sectional study and was performed between 2011 and 2012. The inclusion criteria were age >20 years and a diagnosis of CKD for at least 90 days. Data from medical records were collected, clinical oral examination was performed, and data were statistically analysed. Results A total of 129 patients with different stages of CKD were included. Ninety-eight (76%) were men. The age range was 30–86 years. The Decay, Missing and Filling Tooth Index and the number of missing teeth were higher in the group with moderate CKD than in the control group (21 vs 17.5, p=0.045, 13 vs 8 p=0.01, respectively). Serum albumin levels decreased when estimated glomerular filtration rate (eGFR) was in decline (γ=0.33; p=0.002). Severe periodontitis was significantly higher in the ‘more severe CKD group’ (eGFR <60 mL/min/1.73 m2) than in the ‘less severe CKD group’ (eGFR 60–90 mL/min/1.73 m2; 24% vs 9%, p=0.03). Severe periodontitis, eGFR <30 mL/min/1.73 m2 and brushing teeth more than once a day were associated with hypoalbuminaemia (defined as <3.8 g/dL) (OR (95% CI) 5.88 (1.64 to 21.11), 5.80 (1.58 to 21.35) and 0.16 (0.05 to 0.60), respectively). Conclusions Severe periodontal diseases were more prevalent in patients with more severe CKD than in those with less severe CKD. The novel association of serum albumin levels with periodontal status was demonstrated in progressive stages of CKD. Dental intervention may be beneficial from the early stages of CKD. PMID:27466240

    Background and Objectives: Coenzyme Q10 is a well studied antioxidant in medical literature, but studies regarding its efficacy in periodontal diseases are few. Hence, the aim of this study was to test the efficacy of coenzyme Q10 in the form of gel (Perio-Q) in patients with chronic gingivitis and periodontitis. Materials and Methods: A total of 12 patients were enrolled. A split mouth design was used for topical (extrasulcular) application, intra-pocket application alone, intra-pocket application combined with scaling and root planing (SRP) and SRP only in each quadrant, respectively. Clinical parameters such as plaque index, gingival index, gingival bleeding index, probing pocket depth, clinical attachment level were assessed at baseline, 3rd week, and 6th week. The results were subjected to statistical analysis, which were expressed as mean±SD and proportions as percentages. Intra group comparisons were made by paired t-test and one way analysis of variance (ANOVA) for inter-group comparisons. Categorical data was analyzed by Fisher's exact test. Results: The results showed on intra-group analysis significant reduction (P<0.01) of clinical parameters (plaque index (PI), gingival index (GI), gingival bleeding index (GBI), periodontal probing pocket depth (PPD), and clinical attachment level (CAL)) in all four treatment groups, whereas on inter-group analysis, intra-pocket gel application in combination with SRP showed significant reduction (P<0.05) for PI, GI, GBI, and CAL in comparison to intra-pocket gel alone. Interpretation and Conclusion: In the present study, in chronic periodontitis patients, sub-gingival mechanical debridement only and with Perio-Q gel showed almost similar clinical results without any statistically significant differences. Hence, it confirmed the primary role of basic mechanical approaches in periodontal therapy and did not provide enough clinical support for the superiority of adjunctive use of Perio-Q gel. However, it appears that

    Fifty periodontitis patients and 30 healthy patients with oral cavities were selected from the Faculty of Dentistry, Mahidol University, Bangkok, Thailand, from March 2001 to November 2002. Their ages varied between 15 and 70 years. Among the periodontitis patients, specimens were collected from both disease and healthy sites. All samples were evaluated for the presence of CMV, HHV-6, and EBV-1 by nested PCR. Among the periodontitis patients, CMV was found in 34%, of which 8% were at the disease sites, 10% were at the healthy sites, and 16% were from both sites. EBV was not found in this group of the patients, while HHV-6 was found in 4%, at the disease sites only. CMV was found in one (3.3%) healthy control while HHV-6 and EBV-1 were not found. The depth of sample sites, various demographic and baseline characteristics eg sex, age, occupation and root planning were not associated with the presence of these viruses.

    Objective: The aim of this prospective study was to compare the periodontal health and the microbiological changes via real-time polymerase chain reaction (PCR) in patients treated with fixed orthodontic appliances and Invisalign® system (Align Technology, Santa Clara, California). Materials and Methods: Seventy-seven patients were enrolled in this study and divided into three groups (Invisalign® group, fixed orthodontic appliances group and control group). Plaque index, probing depth, bleeding on probing were assessed. Total biofilm mass and periodontal pathogens were analyzed and detected via real-time PCR. All these data were analyzed at the T0 (beginning of the treatment) T1 (1-month) and T2 (3 months); and statistically compared using the Mann–Whitney test for independent groups. Results: After 1-month and after 3 months of treatment there was only one sample with periodontopathic anaerobes found in patient treated using fixed orthodontic appliances. The Invisalign® group showed better results in terms of periodontal health and total biofilm mass compared to the fixed orthodontic appliance group. A statistical significant difference (P < 0.05) at the T2 in the total biofilm mass was found between the two groups. Conclusion: Patients undergoing orthodontic treatment with the Invisalign® System show a superior periodontal health in the short-term when compared to patients in treatment with fixed orthodontic appliances. Invisalign® should be considered as a first treatment option in patients with risk of developing periodontal disease. PMID:26430371

    Purpose The aim of this study was to compare and analyze the peri-implant tissue conditions and prospective clinical outcomes associated with 2 types of hydroxyapatite (HA)-coated implants: (1) fully HA-coated implants and (2) partially HA-coated implants with resorbable blast medium on the coronal portion of the threads. Methods Forty-four partially edentulous patients were randomly assigned to undergo the placement of 62 HA-coated implants, and were classified as the control group (partially HA-coated, n=30) and the test group (fully HA-coated, n=32). All patients had chronic periodontitis with moderate crestal bone loss around the edentulous area. The stability and clinical outcomes of the implants were evaluated using the primary and secondary implant stability quotient (ISQ), as well as radiographic, mobility, and peri-implant soft tissue assessments around the implants. The Wilcoxon signed-rank test and the Mann-Whitney test were used to evaluate differences between and within the 2 groups, with P values <0.05 considered to indicate statistical significance. Results The fully HA-coated implants displayed good retention of crestal bone, and insignificant differences were found in annual marginal bone loss between the 2 types of HA-coated implants (P>0.05). No significant differences were found in the survival rate (group I, 100%; group II, 100%) or the success rate (group I, 93.3%; group II, 93.8%). The fully HA-coated implants also did not significantly increase the risk of peri-implantitis (P>0.05). Conclusions The fully HA-coated implants did not lead to an increased risk of peri-implantitis and showed good retention of the crestal bone, as well as good survival and success rates. Our study suggests that fully HA-coated implants could become a reliable treatment alternative for edentulous posterior sites and are capable of providing good retention of the crestal bone.

    To determine the genetic diversity of cultivable and uncultivable spirochetes in the gingival crevice of a patient with severe periodontitis, partial 16S rRNA genes were cloned from PCR-amplified products of DNA and RNA extracted from a subgingival plaque sample. Approximately 500 bp were amplified in PCRs by using universally conserved primers with polylinker tails. Purified PCR products were cloned into Escherichia coli by using the plasmid vector pUC19. The resultant clone library was screened by colony hybridization with a radiolabeled, treponeme-specific oligonucleotide probe. The 16S rRNA inserts of 81 spirochetal clones were then sequenced by standard procedures. Sequences were compared with 16S rRNA sequences of 35 spirochetes, including the four known cultivable oral treponeme species. The analysis revealed an unexpected diversity of oral treponemes from a single patient. When 98% or greater sequence similarity was used as the definition of a species-level cluster, the clone sequences were found to represent 23 species. When 92% similarity was used as the definition, the clones fell into eight major groups, only two of which contained named species, Treponema vincentii and Treponema denticola, while Treponema pectinovorum and Treponema socranskii were not represented in any cluster. Seven of the 81 spirochetal clones were found to contain chimeric 16S rRNA sequences. In situ fluorescence hybridization with a fluorescein isothiocyanate-labeled oligonucleotide probe specific for one of the new species representing cluster 19 was used to identify cells of the target species directly in clinical samples.

    Today's knowledge and studies show a firm correlation between osteoporosis and periodontitis, particularly in postmenopausal women. This review study deals with epidemiological and etiopathogenetic association between chronic periodontitis and an osteoporosis. A special emphasis is put on explanation of possible relations between a premature tooth loss and decrease of length and density of jaw bones, particularly their alveolar prolongations. The second part of the paper deals with principles of treatment in patients suffering of osteoporosis. Osteoporosis reduces density of jaw bones and decreases a number of teeth in jaws, but it does not affect other clinical signs and markers of periodontitis such as inflammation, bleeding and the depth of periodontal pockets and microbial plaque.

  18. Effect of periodontal treatment on the clinical parameters of patients with rheumatoid arthritis: study protocol of the randomized, controlled ESPERA trial

    PubMed Central

    2013-01-01

    Background Rheumatoid arthritis (RA) is a chronic inflammatory disorder that leads to joint damage, deformity, and pain. It affects approximately 1% of adults in developed countries. Periodontitis is a chronic oral infection, caused by inflammatory reactions to gram-negative anaerobic bacteria, and affecting about 35 to 50% of adults. If left untreated, periodontitis can lead to tooth loss. A significant association has been shown to exist between periodontitis and RA in observational studies. Some intervention studies have suggested that periodontal treatment can reduce serum inflammatory biomarkers such as C-reactive protein, or erythrocyte sedimentation rate. We hypothesize that periodontitis could be an aggravating factor in patients with RA, and that its treatment would improve RA outcomes. The aim of this clinical trial is to assess the effect of periodontal treatment on the biological and clinical parameters of patients with RA. Methods/design The ESPERA (Experimental Study of Periodontitis and Rheumatoid Arthritis) study is an open-label, randomized, controlled trial. Subjects with both RA and periodontitis will be recruited at two university hospitals in southwestern France. In total, 40 subjects will be randomized into two arms (intervention and control groups), and will be followed up for 3 months. Intervention will consist of full-mouth supra-gingival and sub-gingival non-surgical scaling and root planing, followed by systemic antibiotic therapy, local antiseptics, and oral hygiene instructions. After the 3-month follow-up period, the same intervention will be applied to the subjects randomized to the control group. The primary outcome will be change of in Disease Activity Score in 28 Joints (DAS28) at the end of the follow-up period. Secondary outcomes will be the percentages of subjects with 20%, 50%, and 70% improvement in disease according to the American College of Rheumatology criteria.

    We evaluated results of temozolomide (TMZ) therapy in six patients, aged 34–78 years, presenting aggressive pituitary tumors. In all the patients tested O6-methylguanine-DNA methyltransferase (MGMT) immunoexpression in surgical specimens was absent. Patients received temozolomide 140–320 mg/day for 5 days monthly for at least 3 months. In two patients minimum time for evaluation could not be reached because of death in a 76-year-old man with a malignant prolactinoma and of severe neutro-thrombopenia in a 47-year-old woman with nonfunctioning pituitary adenoma. In two patients (a 34-year-old acromegalic woman and a 39-year-old woman with Nelson's syndrome) no response was observed after 4 and 6 months, respectively, and the treatment was stopped. Conversely, two 52- and 42-year-old women with Cushing's disease had long-term total clinical and radiological remissions which persisted after stopping temozolomide. We conclude that TMZ therapy may be of variable efficacy depending on—until now—incompletely understood factors. Cooperative work on a greater number of cases of aggressive pituitary tumors should be crucial to establish the indications, doses, and duration of temozolomide administration. PMID:26106414

    Diabetes mellitus (DM) and chronic periodontitis are common chronic diseases in adults in the world population. DM has a strong influence on the oral cavity and represents a risk factor for gingivitis and periodontitis. Low-level laser therapy (LLLT) has proven effective in the reduction of inflammation and swelling. The aim of the present study was to evaluate the efficacy of LLLT in diabetic periodontitis through histological analysis. A total of 300 diabetics with chronic periodontal disease and teeth indicated for extraction were assigned into six equal groups. In the groups 1 and 4, indicated teeth were extracted before treatment, and in the rest of the groups upon completion of the entire treatment. All patients received oral hygiene instructions and full-mouth conservative periodontal treatment. In groups 3 and 6, LLLT was applied (670 nm, 5 mW, 2 J/cm(2), 16 min, 5 days). Histologic findings of gingival tissue treated with LLLT showed expressed healing, as is evident by the absence of inflammatory cells. Tissue edema could not be seen, and the number of blood vessels was reduced. In the gingival lamina, propria pronounced collagenization and homogenization were present. It can be concluded that LLLT has shown efficacy in the treatment of periodontitis in diabetics. Because of more pronounced alterations of periodontium in diabetics, the use of LLLT is of particular importance.

    Objective The present study was designed to examine the relationship between prior partner and non-partner aggression and suicidal ideation in patients seeking drug and alcohol treatment. Method Patients entering drug and alcohol treatment (n = 488) were screened for prior partner and non-partner aggression as well as recent suicidal thoughts. We examined the association between aggression and suicidal ideation in bivariate and multivariate models. Results Within the past two weeks, 33% (159/488) of the sample reported suicidal ideation. In bivariate analyses, neither psychological nor physical aggression towards a non-partner was related to suicidal ideation. Partner psychological aggression was related to suicidal ideation in bivariate but not multivariate analyses. Physical aggression towards a partner was consistently related to higher rates of suicidal ideation even after controlling for other known risk factors (OR = 1.8; CI = 1.1 - 2.7). Mediational analyses indicate that this relationship was no longer significant after accounting for current negative affect. Conclusion Suicidal ideation is common in patients seeking drug and alcohol treatment and particularly likely in those who report prior aggression towards a partner. PMID:18977093

    Fusobacterium nucleatum is one of the most abundant gram-negative bacilli colonizing the subgingival plaque and closely associated with periodontal disease. However it is unclear whether F. nucleatum is involved in gingival inflammation under orthodontic appliance. A novel adhesin, FadA, which is unique to oral Fusobacteria, is required for F. nucleatum binding and invasion to epithelial cells and thus may play an important role in colonization of Fusobacterium in the host. In this study, we evaluated the prevalence of F. nucleatum and its virulence factor FadA adhesion gene (fadA) in 169 subgingival biofilm samples from 55 cases of gingivitis patients with orthodontic appliances, 49 cases of gingivitis patients without orthodontic treatment, 35 cases of periodontitis patients and 30 cases of periodontally healthy people via PCR. The correlations between the F. nucleatum/fadA and gingivitis index(GI)was also analyzed. The detection rate of F. nucleatum/fadA in periodontitis group and non-orthodontic gingivitis group was higher than the other two groups (p<0.01) while it was higher in orthodontic gingivitis group than in health people (p<0.05). An obviously positive correlation was observed between the prevalence of F. nucleatum/fadA and GI. F. nucleatum carrying fadA may be more closely related to the development of gingivitis and periodontal disease compared with orthodontic gingivitis.

    Aim of the study The present study investigated the hypothesis that upregulation of receptor activator of NF-kappaB ligand (RANKL) expression may be associated with upregulation of endothelial cell activitiy, which is common for periods of periodontal bone loss in chronic periodontitis. Material and methods RANKL expression of activated cells in soft tissue biopsies with CD 31 activity and the presence of RANKL and osteoprotegerin (OPG) in gingival crevicular fluid (GCF) were assessed in chronic periodontitis patients. Biopsies from 17 patients and 10 healthy subjects were immunohistochemically analyzed. Clinical measurements [plaque index (PI), the gingival index (GI), probing pocket depth (PPD), clinical attachment level (CAL) and gingival bleeding index (GBI)] and GCF samples were obtained before and after periodontal therapy. Results CD31 staining did not support the assumption that endothelium-like cells were predominantly associated with RANKL expression. Conclusions RANKL-positive cells were widely distributed in periodontitis patients giving only partial support to the hypothesis that RANKL expression is restricted to T- and B-cell activation.

In this study, we evaluated the prevalence of F. nucleatum and its virulence factor FadA adhesion gene (fadA) in 169 subgingival biofilm samples from 55 cases of gingivitis patients with orthodontic appliances, 49 cases of gingivitis patients without orthodontic treatment, 35 cases of periodontitis patients and 30 cases of periodontally healthy people via PCR. The correlations between the F. nucleatum/fadA and gingivitis index(GI)was also analyzed. The detection rate of F. nucleatum/fadA in periodontitis group and non-orthodontic gingivitis group was higher than the other two groups (p<0.01) while it was higher in orthodontic gingivitis group than in health people (p<0.05). An obviously positive correlation was observed between the prevalence of F. nucleatum/fadA and GI. F. nucleatum carrying fadA may be more closely related to the development of gingivitis and periodontal disease compared with orthodontic gingivitis. PMID:24416378

    Introduction: The aim of the study was to assess changes in Transforming Growth Factor– β1 (TGF-β1) levels in gingival crevicular fluid (GCF) and examine correlation of TGF-β1 levels and periodontal parameters: probing pocket depth (PPD) and clinical attachment level (CAL) in sites with chronic periodontitis at various time intervals before and after periodontal surgery. Materials and Methods: The effects of non-surgical and surgical therapy on periodontal parameters and GCF TGF-β1 levels in 18 sites affected with chronic periodontitis were assessed upto 6 weeks post conventional flap surgery. GCF was collected and PPD, CAL recorded at Baseline. GCF was collected and PPD, CAL recorded at Pre-surgery and flap surgery performed. GCF was collected from all sites at Two Weeks Post-surgery. GCF was collected and PPD, CAL recorded at Six Weeks Post-surgery. The concentration of TGF-β1 in GCF was determined using a human TGF-β1 enzyme immunometric assay kit. Results: Mean TGF-β1 concentrations were significantly reduced at Pre-surgery, at Two Weeks Post-surgery and at Six Weeks Post-surgery (p<0.05) when compared to Baseline TGF-β1 values. There was a statistically significant reduction in PPD and gain in CAL following non-surgical and surgical therapy when compared to baseline (p<0.05). Conclusion: Results indicate that TGF-β1 may play a role in the pathogenesis and diagnosis of periodontal disease and could be considered as a disease predictive biomarker. PMID:25859517

    Patient: Male, 74 Final Diagnosis: Rasburicase-induced methemoglobinemia Symptoms: Acute shortness of breath Medication: Rasburicase Clinical Procedure: Attempted percutaneous coronary intervention (PCI) Specialty: Oncology Objective: Unusual or unexpected effect of treatment Background: Rasburicase is a recombinant urate oxidase enzyme that converts uric acid to allantoin (an inactive and soluble metabolite that is readily excreted in urine). It is used for the management of tumor lysis syndrome (TLS) in cancer patients receiving chemotherapy. Although rasburicase is a generally safe and effective treatment, it can be associated with the rare and potentially severe complication of methemoglobinemia. Here, we report a case of rasburicase-induced methemoglobinemia in a patient who was diagnosed with aggressive non-Hodgkin’s lymphoma. Case Report: A 74-year-old man with aggressive non-Hodgkin’s lymphoma was admitted for initiation of chemotherapy. Upon admission, the patient was found to have hyperkalemia, hyperuricemia, hyperphosphatemia, elevated LDH levels, and acute renal failure. As a result, he was diagnosed with TLS. Rasburicase 6 mg was administered intravenously over a period of 30 min to treat TLS. Later, methemoglobinemia developed, with requirements for oxygen supplementation. Multiple units of packed red blood cells were transfused for recurrent significant anemia secondary to his cancer co-morbidity. The patient was tested for glucose-6 phosphate dehydrogenase (G6PD) deficiency, which returned negative; therefore, methylene blue was considered. After transfusion, the methemoglobin level normalized over the course of a few days, and the oxygen saturation improved without the use of methylene blue. However, during his hospitalization, the patient also developed a pulmonary embolism and had evidence of acute coronary syndrome. Later, the patient died of multiple complications related to his cancer co-morbidity on day 12 of admission. Conclusions: Blood

    The purpose of this study was to determine the prevalence of enteric bacteria and yeasts in biofilm of 80 HIV-positive patients with plaque-associated gingivitis or necrotizing periodontitis. Patients were subjected to extra, intra oral and radiographic examinations. The oral hygiene, bleeding on probing, gingival conditions, and attachment loss were evaluated. Clinical specimens were collected from gingival crevices or periodontal pockets, transferred to VMGA III, diluted and transferred to Sabouraud Dextrose agar with 100 μg/ml of chloramphenicol, peptone water, EVA broth, EMB agar, SS agar, Bile esculin agar and Brilliant green agar. Isolation of yeasts was carried out at room temperature, for 3-7 days; and for the isolation of enteric microorganisms plates were incubated at 37°C, for 24-48 h. The yeasts identification was performed according to the carbon and nitrogen assimilation, fermentation of carbohydrates and germ tube formation. Bacteria were identified according to their colonial and cellular morphologies and biochemical tests. Yeasts were identified as Candida albicans and its occurrence was more common in patients with CD4+ below 200/mm3 and was affected by the extension of periodontal involvement (P = 0.0345). Enteric bacteria recovered from clinical specimens were identified as Enterobacter sakazakii, Enterobacter cloacae, Serratia liquefaciens, Klebsiella oxytoca and Enterococcus sp. Enterobacteriaceae and enterococci were detected in 32.5% of clinical samples from patients with necrotizing periodontitis. In conclusion, non-oral pathogenic bacteria and C. albicans were more prevalent in periodontal sites of HIV-positive patients with necrotizing periodontitis and chronic gingivitis. PMID:24031212

    Studies to elucidate the role of genetics as a risk factor for periodontal disease have gone through various phases. In the majority of cases, the initial 'hypothesis-dependent' candidate-gene polymorphism studies did not report valid genetic risk loci. Following a large-scale replication study, these initially positive results are believed to be caused by type 1 errors. However, susceptibility genes, such as CDKN2BAS (Cyclin Dependend KiNase 2B AntiSense RNA; alias ANRIL [ANtisense Rna In the Ink locus]), glycosyltransferase 6 domain containing 1 (GLT6D1) and cyclooxygenase 2 (COX2), have been reported as conclusive risk loci of periodontitis. The search for genetic risk factors accelerated with the advent of 'hypothesis-free' genome-wide association studies (GWAS). However, despite many different GWAS being performed for almost all human diseases, only three GWAS on periodontitis have been published - one reported genome-wide association of GLT6D1 with aggressive periodontitis (a severe phenotype of periodontitis), whereas the remaining two, which were performed on patients with chronic periodontitis, were not able to find significant associations. This review discusses the problems faced and the lessons learned from the search for genetic risk variants of periodontitis. Current and future strategies for identifying genetic variance in periodontitis, and the importance of planning a well-designed genetic study with large and sufficiently powered case-control samples of severe phenotypes, are also discussed.

    Oral cavity squamous cell carcinoma may be more aggressive at presentation and recurrence in young patients compared with older patients. Dysregulation of microRNAs (miRNAs or miRs) has been associated with the development and prognosis of oral cavity cancer. The present study investigated miRNA expression in carcinoma of the oral tongue in young patients. miRNA expression profiles were evaluated in formalin-fixed, paraffin-embedded samples of tumor and normal mucosa from 12 patients aged <30 years old with squamous cell carcinoma of the tongue. The levels of let-7f-5p, miR-30b-5p and let-7e-5p were upregulated in tumors (P<0.05). The expression of let-7f-5p was upregulated in non-aggressive tumors, while the expression of let-7e-5p was upregulated in aggressive tumors, compared with the corresponding normal tissue. Aggressive tumors had higher levels of let-7c, miR-130a-3p, miR-361-5p, miR-99a-5p, miR-29c-3p and let-7d-5p than non-aggressive tumors (P<0.05). The findings remained significant for let-7c upon false-discovery rate correction. An excellent correlation was noticed on validation of NanoString counts by quantitative polymerase chain reaction. The comparison with published findings in adults demonstrated a unique miRNA signature in young patients with aggressive disease. Aggressive oral cavity cancer in patients <30 years old is associated with a distinctive expression pattern of the let-7 family. Larger studies including direct comparison with older patients are warranted. PMID:27602107

    Periodontitis is an inflammatory disease affecting the periodontium i.e. the tissues that surround and support the teeth. Periodontitis manifests as progressive loss of the alveolar bone around the teeth, and if left untreated, can cause loosening and subsequent loss of teeth. Periodontitis is initiated by microorganisms that adhere to and grow on the tooth's surfaces, besides an over -aggressive immune response against these microorganisms. The primary goal of periodontal therapy is to preserve the natural dentition by accomplishing and preserving a healthy functional periodontium. Many treatment modalities have been introduced to improve the therapeutic result of periodontal treatment which may also damage the periodontiumiatrogenically. PMID:26312087

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

    2014-01-01

    Background The objective of this paper is to quantify the cost of periodontitis management at public sector specialist periodontal clinic settings and analyse the distribution of cost components. Methods Five specialist periodontal clinics in the Ministry of Health represented the public sector in providing clinical and cost data for this study. Newly-diagnosed periodontitis patients (N = 165) were recruited and followed up for one year of specialist periodontal care. Direct and indirect costs from the societal viewpoint were included in the cost analysis. They were measured in 2012 Ringgit Malaysia (MYR) and estimated from the societal perspective using activity-based and step-down costing methods, and substantiated by clinical pathways. Cost of dental equipment, consumables and labour (average treatment time) for each procedure was measured using activity-based costing method. Meanwhile, unit cost calculations for clinic administration, utilities and maintenance used step-down approach. Patient expenditures and absence from work were recorded via diary entries. The conversion from MYR to Euro was based on the 2012 rate (1€ = MYR4). Results A total of 2900 procedures were provided, with an average cost of MYR 2820 (€705) per patient for the study year, and MYR 376 (€94) per outpatient visit. Out of this, 90% was contributed by provider cost and 10% by patient cost; 94% for direct cost and 4% for lost productivity. Treatment of aggressive periodontitis was significantly higher than for chronic periodontitis (t-test, P = 0.003). Higher costs were expended as disease severity increased (ANOVA, P = 0.022) and for patients requiring surgeries (ANOVA, P < 0.001). Providers generally spent most on consumables while patients spent most on transportation. Conclusions Cost of providing dental treatment for periodontitis patients at public sector specialist settings were substantial and comparable with some non-communicable diseases. These findings

    Introduction For any antimicrobial approach to be successful in periodontal therapy, it is important that the antimicrobial agent targets the sub-gingival biofilm by attaining sufficient concentration at the sub-gingival site. Aim The purpose of the present study was to determine and compare the concentrations of ciprofloxacin present in Gingival Crevicular Fluid (GCF) and plasma after its systemic administration. Materials and Methods A total of 20 subjects, in the age group of 30-60 years satisfying the inclusion and exclusion criteria, were chosen from the outpatient Department of Periodontology, Government Dental College and Hospital, Hyderabad and consent was obtained. Subjects were put on oral ciprofloxacin therapy (Baycip, Bayer Corporation) of 500mg twice daily doses for five days to establish steady state tissue levels of the agent. GCF and serum samples were collected at the 72nd hour after the first dose of ciprofloxacin and were compared using unpaired t test. Results The mean gingival index value of the subjects was 1.8 ± 0.59 and the mean probing depth of the subjects taken in the study was 5.724 ± 0.47mm. The results of this study showed that ciprofloxacin concentrations were significantly higher (p<0.001) in GCF than in plasma. Conclusion Results from the present study and those from the earlier studies clearly indicate the ciprofloxacin’s ability to reach and concentrate in infected periodontal sites via GCF. This property of ciprofloxacin may be useful for eradication of periodontal pathogens, thus improving the outcome of periodontal therapy. PMID:27504410

    The function of T cells infiltrating periodontitis lesions is complex and has not been fully elucidated. Here, we established T-cell clones from the gingival tissues of periodontitis patients and examined their gene expression. A total of 57 and 101 T-cell clones were established by means of immobilized anti-CD3 antibody and IL-2 from gingival tissues and peripheral blood, respectively. The gingival T-cell clones were derived from three patients, and the peripheral blood T-cell clones from two of these patients and a further patient whose gingival T-cell clones were not established. Gingival tissues were also obtained from a further 19 periodontitis patients. The expression of cytokines and molecules related to both regulatory function and tissue destruction were examined by means of reverse-transcription polymerase chain reaction. All the gingival T-cell clones expressed mRNA for TGF-beta1, CTLA-4, and CD25, and all the T-cell clones from peripheral blood expressed IFN-gamma and TGF-beta1 mRNAs. Most but not all the T-cell clones from gingival tissues and peripheral blood expressed mRNA for IFN-gamma and, CD25 and CTLA-4, respectively. The frequency of T-cell clones and gingival tissues expressing FOXP3, a possible master gene for mouse CD4(+)CD25(+) regulatory T cells, was very high (97%, 93%, and 100% for gingival T-cell clones, peripheral blood T-cell clones, and gingival tissues, respectively). Whereas the frequency of IL-4-expressing T-cell clones was lower for gingival T-cell clones (70% vs. 87%), the frequency of the gingival T-cell clones expressing IL-10 and IL-17 was higher than peripheral blood T-cell clones (75% vs. 62% for IL-10, 51% vs. 11% for IL-17). A similar expression profile was observed for gingival T-cell clones compared with gingival tissue samples with the exception of IL-4 expression, where the frequency of positive samples was lower in the gingival tissues (70% vs. 11%). These results suggest that the individual T cells infiltrating

    Patient or client aggression towards staff is a risk in healthcare. Healthcare takes place in a variety of settings, including hospitals, community, and Aged Care facilities. A minimal amount is known regarding the existence of safety and training measures available throughout the broad range of hospital and community healthcare services. A web-based survey of the type and frequency of violence experienced by healthcare staff was sent to unit managers working in mental health and older peoples' services of District Health Boards, Non-Governmental Organisations, and Aged Care facilities across New Zealand. One hundred and forty-one managers responded to the survey with a response rate of 79.21%. Managers reported high rates of verbal aggression and assaults against staff within their services. A total of 60% of respondents stated that an increase in assaults against staff was due to an increase in violent events and 43.1% related this to increased staff awareness and reporting of violent events to management. Communication skills and de-escalation training were provided across approximately 95% of organisations. The availability of safety measures including panic buttons, personal alarms, use of security personnel, and police assistance were more widely available and accessible within hospital settings and the community sector was found to mostly rely on police for assistance when violence occurs. The perception of violence is high in healthcare. Prevention and management training is provided in public hospital and aged care setting but not so much in NGOs. All areas of healthcare provision could benefit from increased evidence based aggression prevention programmes. PMID:27127851

    The evidence for an association between systemic diseases and periodontitis is strongest with diabetes mellitus type 2 and cardiovascular disease. There is a moderate association of periodontitis with adverse pregnancy outcomes and rheumatoid arthritis. Periodontal treatment has, on average, a positive effect on reducing systemic infection and improving the condition of the vascular system. For diabetes patients, periodontal treatment can also have a positive effect on metabolic regulation. There is insufficient evidence that periodontal treatment prevents adverse pregnancy outcomes and rheumatoid arthritis.

    Dental plaque deposits are known to be potent stimulants of lymphocyte transformation in patients with periodontal disease but not in normal subjects. Since plaque deposits consist mainly of whole bacteria, the cell walls of the most commonly found organisms in plaque were tested for their capacity to induce lymphocyte transformation. There was a direct correlation between the severity of peridontal disease and the amount of transformation induced by the cell walls of oral bacteria and by solubilized dental plaque. Cord blood leukocytes and lymphocytes from clinically normal people did not respond, which indicates that these stimulants are antigens rather than mitogens. Of the eleven bacteria tested, four members of the family Actinomycetaceae (Actinomyces viscosus, A. israelii, A. naeslundii, and Arachnia propionica), the related Propionibacterium acnes, and an anaerobic gram-negative anaerobic rod (27N). The high prevalence of the former organisms in the mature dental plaque that forms around the gingival crevice area and the potent efficacy with which they stimulate lymphocytes indicates that Actinomyces and certain gram-negative anaerobes may be important etiological agents in chronic periodontal inflammation in man.

    The purpose of this study was to compare the impact of resin restorations placed supragingivally or impinging periodontal biologic width (PBW). Ten patients (aged 19 to 35 years) with at least two contralateral teeth (premolars and molars) in need of proximal subgingival restorations participated. Test group (TG) (impingement of PBW with transsurgical restorations) and control croup (CG) (supragingival restorations after crown lengthening) were randomly assigned. Visible plaque (VP), bleeding on probing (BOP), periodontal probing depth (PPD), and clinical attachment loss (CAL) were evaluated at baseline and at 45, 90, and 180 days, and by transperiodontal probing at baseline and 180 days. Generalized estimating equations, Wald test, and t test were used (P ≤ .05). VP and BOP were reduced and maintained at low levels (less than 10% from day 45 on). PPD initially reduced in the TG. At day 180, no intra- or intergroup differences were observed (P > .05). CAL was higher in the CG after surgery (P < .05) and remained stable for both groups throughout the study. In conclusion, proximal bonded restorations infringing on the PBW may not require clinical crown lengthening.

    We report here the case of a woman with Class III malocclusion and advanced periodontal disease who was treated with surgical orthodontic correction. Functional recovery after orthodontic treatment is often monitored by serial electromyography of the masticatory muscles, whereas 3-dimensional cone-beam computed tomography can provide detailed structural information about, for example, periodontal bone defects. However, it is unclear whether the information obtained via these methods is sufficient to determine the treatment goal. It might be useful to address this issue for patients with advanced periodontal disease because of much variability between patients in the determination of treatment goals. We used detailed information obtained by 3-dimensional cone-beam computed tomography to identify periodontal bone defects and set appropriate treatment goals for inclination of the incisors and mandibular surgery. Results for this patient included stable occlusion and improved facial esthetics. This case report illustrates the benefits of establishing treatment goals acceptable to the patient, based on precise 3-dimensional assessment of dentoalveolar bone, and by using masticatory muscle activity to monitor the stability of occlusion.

    Background Chronic periodontitis (CP), atherosclerotic and aortic aneurysmal vascular diseases (VD) are chronic inflammatory conditions with multifactorial etiologies, including involvement of predisposing genetic factors. In a previous study, polymorphisms in the gene for the anti-inflammatory interleukin-1 receptor antagonist were associated with CP in patients with VD. Objective This study investigates whether polymorphisms in the gene for the anti-inflammatory interleukin-10 (IL10) could be related to CP in the same manner. Methods Seventy-two patients with VD of whom 35 had CP were genotyped for single nucleotide polymorphisms (SNPs) in the IL10 −592 (rs1800872), −819 (rs1800871), and −1,082 (rs1800896) gene by Taqman rtPCR method and by DNA sequencing. Results The C alleles and C/C genotypes of IL10 −592 and IL10 −819 frequencies were significantly higher, while the frequencies of the IL10 −592 (C/A) and IL10 −819 (C/T) heterozygote genotypes were significantly lower in the VD group with CP compared to those without CP. The IL10 haplotype ATA frequency (−1,082, −819, −592) showed a trend to a significant difference between the two groups indicating protection against CP. Conclusions Taken together, our findings suggest an independent association of genetic polymorphisms in the IL-10 gene locus with CP in patients with VD. Development of CP and the implications on vascular disease emphasize the importance of early detection and adequate treatment of periodontitis among these patients. PMID:25700628

    Evolution of periodontal disease is one of the most important data for the clinicians in order to achieve correct planning and treatment. Clinical measure of the periodontal sulcus depth is the most important datum to know the exact state of periodontal disease. These measures must be done periodically study bone resorption evolution around teeth. Time factor of resorption indicates aggressiveness of periodontitis. Manual probes are commonly used with direct reading. Mechanical probes give automatic signal but this method uses complicated and heavy probes that are only limited for University researchers. Probe position must be the same to have right diagnosis. Digital image analysis of periodontal probing provides practical, accurate and easy tool. Gum and plaque index could also be digitally measured with this method.

    Periodontal disease results from inflammation of the supporting structure of the teeth and in response to chronic infection caused by various periodontopathic bacteria. The mechanical removal of this biofilm and adjunctive use of antibacterial disinfectants and antibiotics have been the conventional methods of periodontal therapy. However, the removal of plaque and the reduction in the number of infectious organisms can be impaired in sites with difficult access. Photodynamic therapy (PDT) is a powerful laser-initiated photochemical reaction, involving the use of a photoactive dye (photosensitizer) activated by light of a specific wavelength in the presence of oxygen. Application of PDT in periodontics such as pocket debridement, gingivitis, and aggressive periodontitis continue to evolve into a mature clinical treatment modality and is considered as a promising novel approach for eradicating pathogenic bacteria in periodontitis.

    Purpose It is important to balance the appropriateness of active cancer treatments and end-of-life care to improve the quality of life for terminally ill cancer patients. This study describes the treatment patterns and end-of-life care in terminal gastric cancer patients. Materials and Methods We retrospectively analyzed the records of 137 patients with advanced gastric cancer receiving chemotherapy and dying between June 1, 2006 and May 31, 2011. We recorded interval between last chemotherapy dose and death; frequency of emergency room visits or admission to the intensive care unit in the last month before death; rate of hospice referral and agreement with written do-not-resuscitate orders; and change in laboratory values in the last three months before death. Results During the last six months of life, 130 patients (94.9%) received palliative chemotherapy; 86 (62.7%) during the final two months; 41 (29.9%) during the final month. During the final month, 53 patients (38.7%) visited an emergency room more than once; 21 (15.3%) were admitted to the intensive care unit. Hospice referral occurred in 54% (74 patients) of the patients; 93.4% (128 patients) gave written do-not-resuscitate orders. Platelets, aspartate aminotransferase and creatinine changed significantly two weeks before death; total bilirubin, one month before; and C-reactive protein, between four and two weeks before death. Conclusion Our results demonstrated that a significant proportion of gastric cancer patients received palliative chemotherapy to the end of life and the patients who stopped the chemotherapy at least one month before death had a lower rate of intensive care unit admission and longer overall survival than those who sustained aggressive chemotherapy until the last months of their lives.

    Distinguishing aggressive from indolent disease and developing effective therapy for advanced disease are the major challenges in prostate cancer research. Chromosomal rearrangements involving ETS transcription factors, such as ERG and ETV1, occur frequently in prostate cancer. How they contribute to tumorigenesis and whether they play similar or distinct in vivo roles remain elusive. Here we show that in mice with ERG or ETV1 targeted to the endogenous Tmprss2 locus, either factor cooperated with loss of a single copy of Pten, leading to localized cancer, but only ETV1 appeared to support development of invasive adenocarcinoma under the background of full Pten loss. Mechanistic studies demonstrated that ERG and ETV1 control a common transcriptional network but largely in an opposing fashion. In particular, while ERG negatively regulates the androgen receptor (AR) transcriptional program, ETV1 cooperates with AR signaling by favoring activation of the AR transcriptional program. Furthermore, we found that ETV1 expression, but not that of ERG, promotes autonomous testosterone production. Last, we confirmed the association of an ETV1 expression signature with aggressive disease and poorer outcome in patient data. The distinct biology of ETV1-associated prostate cancer suggests that this disease class may require new therapies directed to underlying programs controlled by ETV1.

    A key question in cancer systems biology is how to use molecular data to predict the biological behavior of tumors from individual patients. While genomics data have been heavily used, protein signaling data are more directly connected to biological phenotype and might predict cancer phenotypes such as invasion, metastasis, and patient survival. In this study, we mined publicly available data for colorectal adenocarcinoma from the Cancer Genome Atlas and identified protein expression and signaling changes that are statistically associated with patient outcome. Our analysis identified a number of known and potentially new regulators of colorectal cancer. High levels of insulin growth factor binding protein 2 (IGFBP2) were associated with both recurrence and death, and this was validated by immunohistochemical staining of a tissue microarray for a secondary patient dataset. Interestingly, GATA binding protein 3 (GATA3) was the protein most frequently associated with death in our analysis, and GATA3 expression was significantly decreased in tumor samples from stage I-II deceased patients. Experimental studies using engineered colon cancer cell lines show that exogenous expression of GATA3 decreases three-dimensional colony growth and invasiveness of colon cancer cells but does not affect two-dimensional proliferation. These findings suggest that protein data are useful for biomarker discovery and identify GATA3 as a regulator of colorectal cancer  aggressiveness. PMID:26097693

    PubMed Central

    2013-01-01

    Background Mooren’s ulcer is a severe ulcerative inflammation of the cornea. The exact pathogenesis remains unclear. Therefore many therapies of Mooren’s ulcer are recommended in literature. To shed more light on the ongoing question of optimal treatment of severe progressive Mooren’s ulcer, we here report on a retrospective case series of patients treated with systemic immunosuppressive therapy and additional amniotic membrane transplantation. Methods Medical records from seven patients (eleven eyes), 4 male and 3 female, with severe progressive Mooren’s ulcer were analysed retrospectively. The mean follow up was 88.4 ± 80.8 months (range 12–232 month). A HLA-typing was performed in all patients. A systemic immunosuppressive therapy was administered in all patients. The amniotic membrane was transplanted after the base of the ulcer was resected. Results Multiple amniotic membrane transplantations were necessary in six patients. The visual outcome of all patients was poor. No patient achieved a visual acuity better than 20/630 Snellen chart. Five patients were positive for HLA-DQ2 and four patients were positive for HLA-DR17(3). Conclusions The aggressive and highly inflammatory form of Mooren’s ulcer is difficult to treat and the progression of the disease is hard to influence positively even under systemic immunosuppressive therapy. Therefore, the main intention of therapy is to achieve a stable epithelialized corneal surface without the risk of perforation. Amniotic membrane transplantation is not able to cure severe forms of Mooren’s ulcer. However it supports the immunosuppressive therapy in acute situations as in critical corneal thinning.

    2015-01-01

    Purpose The goal of this study was to characterize the patterns of antimicrobial resistance and virulence genes in samples of Staphylococcus aureus (S. aureus) isolated from periodontitis patients. Methods From July 2015 to August 2015, oral saliva was collected from a total of 112 patients diagnosed with periodontitis, including 80 outpatients in dental hospitals and 32 patients in dental clinics located in Seoul and Cheonan. The samples were subjected to a susceptibility test to evaluate the prevalence of antimicrobial resistance, and the pathogenic factors and antimicrobial resistance factors in the DNA of S. aureus were analyzed using polymerase chain reaction. Results A susceptibility test against 15 antimicrobial agents showed that 88% of cultures were resistant to ampicillin, 88% to penicillin, and 2% to oxacillin. Resistance to at least two drugs was observed in 90% of cultures, and the most common pattern of multidrug resistance was to ampicillin and penicillin. Enterotoxins were detected in 65.9% of samples. The cell hemolysin gene hld was detected in 100% of cultures and hla was detected in 97.6% of samples. All strains resistant to penicillin and ampicillin had the blaZ gene. The aph(3′)IIIa gene, which encodes an aminoglycoside modifying enzyme, was detected in 46.3% of samples. Conclusions In the treatment of oral S. aureus infections, it is important to identify the pathogenic genes and the extent of antimicrobial resistance. Furthermore, it is necessary to study patterns of antimicrobial resistance and cross-infection in the context of periodontological specialties in which antimicrobials are frequently used, such as maxillofacial surgery, where the frequency of antimicrobial use for minor procedures such as implant placement is increasing.

    Cigarette smoking is a major lifestyle-related risk factor for periodontal diseases. However, the pathophysiological role of cigarette smoking in periodontal disease has yet to be fully elucidated. Here we report that the systemic administration of cigarette smoke condensate or nicotine, which is the major ingredient of cigarette smoke, augmented alveolar bone loss. Concomitantly, the number of osteoclasts in periodontal tissues increased and the expression of receptor activator of nuclear factor κB ligand was upregulated at the ligated side in mice with periodontitis. Nicotine also attenuated alveolar bone repair after ligature removal. These observations highlight the destruction of periodontal tissue by smoking and the unfavorable clinical course of periodontal disease in patients with a cigarette smoking habit. The present study demonstrates that periodontal disease models are useful for elucidating the pathogenesis of cigarette smoking-related periodontal diseases. PMID:27203240

    Rates of diabetes and its associated comorbidities have been increasing in the United States, with diabetic foot ulcer treatment representing a large cost to the patient and healthcare system. These ulcers often result in multiple hospital admissions. This study examined readmissions following inpatient care for a diabetic foot ulcer and identified modifiable factors associated with all-cause 30-day readmissions to the inpatient or emergency department (ED) setting. We hypothesized that patients undergoing aggressive treatment would have lower 30-day readmission rates. We identified patient discharge records containing International Classification of Disease ninth revision codes for both diabetes mellitus and distal foot ulcer in the State Inpatient and Emergency Department databases from the Agency for Healthcare Research and Quality, Healthcare Cost and Utilization Project in Florida and New York, 2011-2012. All-cause 30-day return to care visits (ED or inpatient) were analyzed. Patient demographics and treatment characteristics were evaluated using univariate and multivariable regression models. The cohort included 25,911 discharges, having a mean age of 63 and an average of 3.8 comorbidities. The overall rate of return to care was 30%, and 21% of subjects underwent a toe or midfoot amputation during their index stay. The most common diagnosis codes upon readmission were diabetes mellitus (19%) and infection (13%). Patients with a toe or midfoot amputation procedure were less likely to be readmitted within 30 days (odds ratio: 0.78; 95% confidence interval: 0.73, 0.84). Presence of comorbidities, black and Hispanic ethnicities, and Medicare and Medicaid payer status were also associated with higher odds of readmission following initial hospitalization (p < 0.05). The study suggests that there are many factors that affect readmission rates for diabetic foot ulcer patients. Understanding patients at high-risk for readmission can improve counseling and

    Juvenile Ossifying Fibroma may be considered a fibro-osseous tumor which usually occurs in young children and arises in craniofacial bones, most commonly seen in the maxilla. This kind of lesion usually occurs in young patients and because of its aggrssive nature, clinicians should try to recognize it as soon as possible in order to avoid future functional and aesthetics problems. Moreover, untreated cases over a long period may result in large bone defects during the surgical removal of the lesion. Here reported is a case of a six-year-old girl who developed a rare aggressive fibroma localized in the right upper jaw. The clinical, radiographic and histopathologic findings, plus differential diagnoses of the case and treatement options are also presented. PMID:23771389

    There remains a high prevalence of mild-to-moderate forms of periodontal diseases in both developed and developing countries. Although many periodontal specialty practices currently place strong emphasis on implant surgery, periodontal plastic surgery and esthetics, general dentists and hygienists have often assumed more responsibility than periodontal specialty practices for the diagnosis, treatment, assessment and maintenance, and possible referral, of their patients. To address these current trends and challenges, this volume of Periodontology 2000 presents a series of topics on the basic biological principles of periodontal disease, as well as on approaches to diagnosis, treatment planning and treatment, in what is called 'conservative' or 'noninvasive' periodontal therapy. These topics include risk assessment of the periodontal condition; reduction, elimination and/or control of etiologies and risk factors, including mechanical, antimicrobial and host-modulation approaches; considerations for evaluation of clinical outcomes based on treatment approaches; and selected topics in laser therapy, halitosis and gingival recession.

    The aim of our study was application of chemometric algorithms for multivariate data analysis in efficacy assessment of the local periodontal treatment with doxycycline (DOX). Treatment efficacy was evaluated by monitoring inflammatory biomarkers in gingival crevicular fluid (GCF) samples and clinical indices before and after the local treatment as well as by determination of DOX concentration in GCF after the local treatment. The experimental values from these determinations were submitted to several chemometric algorithms: principal component analysis (PCA), partial least square discriminant analysis (PLS-DA) and orthogonal projection to latent structures-discriminant analysis (OPLS-DA). The data structure and the mutual relations of the selected variables were thoroughly investigated by PCA. The PLS-DA model identified variables responsible for discrimination of classes of data, before and after DOX treatment. The OPLS-DA model compared the efficacy of the two commonly used medications in periodontal treatment, chlorhexidine (CHX) and DOX, at the same time providing insight in their mechanism of action. The obtained results indicate that application of multivariate chemometric algorithms can be used as a valuable approach for assessment of treatment efficacy. PMID:27283484

    Purpose: Papillary carcinoma is the most frequent type of thyroid cancer and was considered the most benign of all thyroid carcinomas, with a low risk of distant metastases. However, there are some variants of papillary thyroid carcinoma that have affinity to spread in many organs, such as: lymph nodes, lungs and bones. Aim: The aim of this study was presentation of a case with papillary carcinoma of the thyroid gland, very persistent and resistant in treatment with I 131. Material and results: A man 56 years old were diagnosed with papillary carcinoma of thyroid gland. He underwent a surgical removal of the tumor and right lobe of thyroid gland. With histopathology examination, were confirmed follicular variant of papillary carcinoma pT4. Two weeks later he underwent total thyroidectomy and was treated with 100 mCi of J 131. Six months later, the value of thyroglobulin was found elevated above upper measured limits (more than 500 ng/ml). Patient underwent surgical removal of 10 metastatic lymph nodes in the left side of the neck and has been treated with 145 mCi of radioiodine I 131. The examination after 5 months shows elevation of thyroglobulin, more than 20000 ng/ml and focally uptake of J 131 in the left lung. Patient was treated once again with 150 mCi radioiodine J 131. Whole body scintigraphy was registered focal uptake of radioiodine in the middle of the left collarbone. After a month, patient refers the enlargement of the lymph node in the right side of the neck. Currently patient is being treated with kinase inhibitor drug sorafenib and ibandronate. We have identified first positive response in treatment. Enlarged lymph node in the neck was reduced and the patient began feeling better. Conclusion: This study suggests that some subtypes of papillary thyroid carcinoma appear to have more aggressive biological course. Subtypes of papillary thyroid carcinoma such as diffuse sclerosing carcinoma, tall cell or columnar cell and insular variants, appears to

However, the molecular mechanism of tumor invasiveness in PTC remains to be elucidated. The aim of this study is to understand the role of Hedgehog (Hh) signaling in tumor aggressiveness in patients with PTC. Subjects were patients who underwent thyroidectomy from 2012 to 2013 in a single institution. Frozen or paraffin-embedded tumor tissues with contralateral-matched normal thyroid tissues were collected. Hh signaling activity was analyzed by quantitative RT-PCR (qRT-PCR) and immunohistochemical (IHC) staining.

    Background and Objectives: Coenzyme Q10 is a well-studied antioxidant in the medical literature, but studies regarding its efficacy in periodontal diseases are few. coenzymeoenzyme Q10 serves as an endogenous antioxidant and its increased concentration in the diseased gingiva effectively suppresses advanced periodontal inflammation. The aim of this study is to evaluate the efficacy of coenzyme Q10 (Perio Q™) as an adjunct to scaling and root planing in patients with chronic periodontitis. Materials and Methods: A total of 18 patients were enrolled for the study. The selected subjects were treated in three different quadrants randomly. The control quadrant was treated by scaling and root planing only, while the other two test quadrants were treated by intra-pocket application of gel combined with scaling or root planing and topical applications combined with scaling and root planning, respectively. Clinical parameters such as plaque index, gingival index, gingival bleeding index and probing pocket depth were assessed at baseline and at the 2nd week and 4th weeks. The results were subjected to statistical analysis. Results: There was a significant improvement in all clinical parameters in the test sites seen at the end of the 4-week period. Sites with bleeding on probing were reduced more in the test group than in the control group. Conclusion: Coenzyme Q10 can be said to have a beneficial effect on periodontitis when used as an adjunct to scaling and root planing. PMID:25210260

Periodontal clinical parameters such as plaque index, gingival index, probing pocket depth, and clinical attachment level were recorded at baseline and 6-week posttherapy. GCF samples collected from each patient were quantified for VEGF level using enzyme-linked immunosorbent assay. Results: The mean GCF VEGF level was increased in CP patients with and without DM compared to healthy patients and SRP therapy caused a statistically significant (P < 0.001) reduction in GCF VEGF level. Conclusion: VEGF is increased in GCF of CP patients with and without DM and that SRP substantially reduces its level in GCF. PMID:27563195

    Periodontitis is a highly prevalent, biofilm-mediated chronic inflammatory disease that results in the loss of the tooth-supporting tissues. It features two major clinical entities: chronic periodontitis, which is more common, and aggressive periodontitis, which usually has an early onset and a rapid progression. Natural killer (NK) cells are a distinct subgroup of lymphocytes that play a major role in the ability of the innate immune system to steer immune responses. NK cells are abundant in periodontitis lesions, and NK cell activation has been causally linked to periodontal tissue destruction. However, the exact mechanisms of their activation and their role in the pathophysiology of periodontitis are elusive. Here, we show that the predominant NK cell-activating molecule in periodontitis is CD2-like receptor activating cytotoxic cells (CRACC). We show that CRACC induction was significantly more pronounced in aggressive than chronic periodontitis and correlated positively with periodontal disease severity, subgingival levels of specific periodontal pathogens, and NK cell activation in vivo. We delineate how Aggregatibacter actinomycetemcomitans, an oral pathogen that is causally associated with aggressive periodontitis, indirectly induces CRACC on NK cells via activation of dendritic cells and subsequent interleukin 12 (IL-12) signaling. In contrast, we demonstrate that fimbriae from Porphyromonas gingivalis, a principal pathogen in chronic periodontitis, actively attenuate CRACC induction on NK cells. Our data suggest an involvement of CRACC-mediated NK cell activation in periodontal tissue destruction and point to a plausible distinction in the pathobiology of aggressive and chronic periodontitis that may help explain the accelerated tissue destruction in aggressive periodontitis.

    Aim: To evaluate the clinical and metabolic changes following nonsurgical periodontal therapy of type-2 diabetic patients and nondiabetic patients. Materials and Methods: Fifteen nondiabetics and fifteen type-2 diabetics with moderate to severe periodontitis were selected after meeting inclusion and exclusion criteria. Periodontal pocket probing was performed using a Williams graduated periodontal probe and comparisons of the clinical and biochemical parameters like plaque index, gingival index, probing depth, glycated hemoglobin, and lipid profile (total cholesterol, high density lipoprotein, low density lipoprotein, triglycerides and very low density lipoprotein) were done between and within two groups at baseline and 3 month. Results: A correlation was observed between clinical and biochemical parameters between and within two groups at baseline and 3 month. The P value of diabetic group was<0.001 in all clinical parameters (plaque index PI, Gingival index GI, and Probing Pocket Depth PPD) in diabetic and nondiabetic group, showed statistically highly significant difference in GI, PI, PPD, <.01 in Glycated Hemoglobulin (HbAlc1) in test group and<0.05 in control group showed statistically significant difference. The P value of test group was >0.05 in Lipid profile (total cholesterol, low density lipoprotein, high density lipoprotein, serum triglyceride, very low density lipoprotein) that showed no significant difference and in control group<0.05 in total Cholesterol, high density lipoprotein and <0.01 in Low density lipoprotein, Very Low Density Lipoprotein, and Serum Triglyceride, respectively, showed statistically significant in Total cholesterol, Low density lipoprotein, Very Low Density Lipoprotein, and Serum Triglyceride, not significant in high density lipoprotein. The P value >0.05 showed no statistical significance of correlation between the test and control groups. Conclusion: Both groups of patients showed an improvement in clinical and metabolic

    The long-term success of osseointegrated oral implants is endangered by inflammation of peri-implant hard and soft tissues caused by bacterial biofilms that may have been initiated by bacterial transmission from the adjacent dentition. The present study aimed to compare the bacterial communities at inflamed implant and tooth sites by broad-range PCR techniques to evaluate the etiological processes of peri-implant and periodontal diseases and potential future therapeutic strategies. Eighteen samples of peri-implant and periodontal microflora were collected from nine partially edentulous patients with implant-retained crowns or bridges revealing clinical signs of gingivitis or mucositis. The clinical parameters plaque index (PI), probing depth (PD), and bleeding on probing were recorded. Amplified fragments of bacterial 16S rRNA genes were separated by use of single-strand conformation polymorphism analysis, and sequences were determined to identify the predominant bacterial genera. The clinical parameters PI and PD were significantly different at implants (PI = 0.4 ± 0.7, PD = 3.1 ± 0.6 mm) compared with teeth (PI = 1.8 ± 0.8, PD = 2.5 ± 0.2 mm). A total of 20 different genera were found at the inflamed tooth and implant sites. The microbial diversity of the microflora surrounding the remaining dentition (12.0 ± 3.8) was significantly higher (p = 0.01) than the diversity of the peri-implant microflora at implant-retained crowns or bridges (6.3 ± 2.3). Within the limitations of the present study, the microbial diversity of the investigated implants and teeth with clinical signs of mucositis or gingivitis exhibits substantial differences, demonstrating that transmission of the complete bacterial microflora from teeth to implants could be excluded. Furthermore, broad-range molecular biological detection methods specify bacterial genera and species in the peri-implant and periodontal microflora which were not in the focus of research interests so far.

    Patient aggression occurs in old age psychiatry and is contrary to their recovery and to the well-being of staff. A favourable social climate can contribute to a reduction in aggression. The aim of this study was to examine the perceptions of clinical staff about the social climate of acute old age psychiatry inpatient units. Eighty-five clinicians were recruited from these facilities. They completed a survey questionnaire about the social climate or ward atmosphere of inpatient units. The findings showed that, to some extent, respondents' perceived patient cohesion and mutual support were evident, units were perceived somewhat positively as safe environments for patients and staff, and the ward climate helped meet patients' therapeutic needs. Overall, clinicians were somewhat positive about the social climate of the units, and this has implications for the perception of aggression in old age psychiatry inpatient settings. As there is a direct relationship between social climate and aggression, clinicians should consider adopting a broad-based, person-centred approach to the promotion of a favourable social climate in old age psychiatry inpatient settings.

    Background: Long term health of the stomatognathic system as well as esthetic aspects is the therapeutic goals in patients with oro facial clefts. Aim: The aim of this study was to assess and compare the periodontal status of patients with cleft lip (CL), cleft palate (CP) and cleft lip, alveolus and palate (CLAP) reporting to a hospital in Chennai, India. Materials and Methods: The study group consisted of 80 cleft patients. Subjects were divided into three groups. Group 1: patients with cleft lip (CL), Group 2: subjects with cleft palate (CP) and Group 3: subjects with cleft lip alveolus and palate (CLAP). Community Periodontal Index for Treatment needs CPITN Index was recorded. Results: Among the 80 study subjects, 51 (63.8%) were males and 29 (36.2%) were females. Among the 26 study subjects with cleft lip, 10 (38.5%) had healthy periodontium, 4 (15.4%) had bleeding on probing and 12 (46.1%) had calculus. Mean number of sextants coded for healthy and bleeding was maximum among the subjects with cleft palate. Mean number of sextants coded for calculus was maximum among the subjects with cleft lip alveolus and palate. Prevalence of periodontal disease is high among patients with cleft lip, alveolus and palate (35%) than in Cleft lip (32.5%) and Cleft Palate (32.5%). Conclusion: Gingivitis and Calculus is predominantly high in patients with Cleft Palate and Cleft Lip respectively. PMID:25954706

    Background and objectives: The severity of liver disease among hepatitis C patients on hemodialysis is controversial. The aim of this study was to compare the clinical, biochemical, and liver histologic characteristics of hepatitis C virus (HCV) in hemodialysis patients and in those with normal renal function. Design, setting, participants, & measurements: A case-control study was carried out with 36 HCV patients on hemodialysis and 37 HCV patients with normal renal function matched for gender, age at infection, and estimated time of infection. Results: HCV patients on hemodialysis had lower levels of alanina aminotransferase and lower viral load. Hepatic fibrosis was significantly higher in the patients with normal renal function (73%) than in hemodialysis patients (47.2%, P < 0.025); the same was observed for inflammatory activity (control group 59.5% versus hemodialysis patients 27.7%, P = 0.003). In addition, the risk of tissue inflammation was four times lower in hemodialysis patients (odds ratio = 0.23, P < 0.004), and severe inflammatory activity on biopsy was the only independent risk factor for fibrosis (P < 0.001). Conclusions: The lower biochemical and inflammatory activities observed in hemodialysis patients suggest that hemodialysis and uremia may have a protective role against progression of the disease caused by HCV.

    Streptococcus salivarius is an oral commensal bacterium that rarely causes disease in humans. Here, we report a case of liver abscess associated with S. salivarius in a 41-year-old woman who presented with continuous abdominal discomfort, fatigue, and fever. She was diagnosed with multiple liver abscesses; she underwent percutaneous transhepatic abscess drainage. Thereafter, S. salivarius was isolated in all bacterial cultures of the drained abscesses, and it was sensitive to penicillins. She made a good recovery after treatment. In the absence of an infective source other than chronic periodontitis, the cause of liver abscesses was attributed to oral S. salivarius. S. salivarius is a normal oral commensal, and oral commensals must be considered if the infective origin of liver abscess cannot be determined. PMID:25100350

    2013-06-01

    This review aims to highlight concepts relating to nonsurgical and surgical periodontal therapy, which have been learned and unlearned over the past few decades. A number of treatment procedures, such as gingival curettage and aggressive removal of contaminated root cementum, have been unlearned. Advances in technology have resulted in the introduction of a range of new methods for use in nonsurgical periodontal therapy, including machine-driven instruments, lasers, antimicrobial photodynamic therapy and local antimicrobial-delivery devices. However, these methods have not been shown to offer significant benefits over and above nonsurgical debridement using hand instruments. The method of debridement is therefore largely dependent on the preferences of the operator and the patient. Recent evidence indicates that specific systemic antimicrobials may be indicated for use as adjuncts to nonsurgical debridement in patients with advanced disease. Full-mouth disinfection protocols have been proven to be a relevant treatment option. We have learned that while nonsurgical and surgical methods result in similar long-term treatment outcomes, surgical therapy results in greater probing-depth reduction and clinical attachment gain in initially deep pockets. The surgical technique chosen seems to have limited influence upon changes in clinical attachment gain. What has not changed is the importance of thorough mechanical debridement and optimal plaque control for successful nonsurgical and surgical periodontal therapy.

    Altered passive eruption/gummy smile is a common challenge in patients requiring aesthetic treatment. A specific surgical protocol was designed and tested in patients with altered passive eruption. Standardized preoperative X-rays were used to assess crown length at baseline and to place submarginal incisions. Osseous respective therapy was performed to achieve biological width. Clinical outcomes were recorded 6 months after surgery. Eleven patients with a total of 58 teeth were treated with flap surgery and osseous resective therapy at upper anterior natural teeth. At the last followup, a significant and stable improvement of crown length was obtained when compared to the baseline (P < 0.0001). All patients rated as satisfactory in the final outcomes (final VAS value = 86.6). In conclusion, this study showed that periodontal plastic surgery including osseous resection leads to predictable outcomes in the treatment of altered passive eruption/gummy smile: A careful preoperative planning avoids unpleasant complications and enhances postsurgical stability of the gingival margin.

    Background Recent studies point to the clinical utility of using peri-implant sulcular fluid (PISF) as a valuable diagnostic aid for monitoring peri-implant tissue health. The objectives of this study were to determine the levels of key biomarkers in PISF in periodontal maintenance participants and compare them to their corresponding levels in gingival crevicular fluid (GCF) obtained from the same participants. Methods PISF and GCF were collected from an implant and a contralateral natural tooth, after the clinical examination of 73 participants. The levels of interleukin (IL)-1α, IL-1β, IL-6, IL-8, IL-10, IL-12, IL-17A, tumor necrosis factor (TNF)-α, C-reactive protein (CRP), osteoprotegerin (OPG), leptin, and adiponectin were determined using multiplex proteomic immunoassays. The correlation of biomarker concentrations between GCF versus PISF, within GCF or PISF, and with several covariates (age, brushing frequency, days since professional cleaning, probing depth and plaque index) were also determined. Results Significantly higher levels of IL-17A (p=0.02) and TNF-α (p=0.03) were noted in PISF, when compared to their levels in GCF. Significant positive correlations were noted between the concentrations of cytokines in PISF versus their levels in GCF. Among the covariates, significant positive correlation was noted between mean probing depths around implants and levels of IL-1β (p < 0.05) and IL-8 levels (p < 0.05) in PISF. Conclusions The results of this study point to the differential expression of specific biomarkers in GCF versus their levels in PISF in periodontal maintenance patients, which is critical information prior to establishing PISF as a diagnostic fluid to monitor peri-implant health.

    Strong evidence indicates that tumor growth can be actively controlled by the immune system, and interleukins (ILs) are known to play an influential role in immune response regulation. Moreover, inflammatory cytokines are significantly involved in lymphoma pathogenesis. We aimed to investigate serum levels of IL-4 and IL-18 in aggressive non-Hodgkin's lymphoma (A-NHL) patients and their relationship with prognostic parameters and therapy outcome. These serum factors were measured by enzyme-linked immunosorbent assay in 46 patients with pathologically verified A-NHL before and after chemotherapy, and in 20 healthy controls. No significant difference in serum IL-4 (P = 0.11) and IL-18 (P = 0.261) levels was observed between the A-NHL and controls groups. None of the prognostic parameters analyzed significantly correlated with serum IL-4 concentration, while only lactate dehydrogenase (LDH) measurements were associated with IL-18 values. Serum IL-18 was elevated in the patients with high LDH levels compared to those exhibiting normal values (P = 0.045). In addition, no correlation was found between the concentrations of serum IL-4 and IL-18 in A-NHL patients (r = 0.188, P = 0.187). While IL-18 values did not change, serum IL-4 levels decreased following chemotherapy, independently from treatment response (P = 0.002). Our study is the first to report the response of serum IL-4 levels to chemotherapy. In conclusion, although IL-4 serum concentration has no diagnostic role, it is sensitivite to standard chemotherapy in A-NHL. However, serum IL-18 measurements have no diagnostic or prognostic role in this disease. PMID:27525895

    An investigation was made of applying pulsed (lambda) equals 0.89 micrometers laser radiation in the treatment for early diagnosed periodontitis. The investigation was made on 65 patients (47 patients constituted the experimental group and 18 patients constituted a control group) affected by periodontitis. Clinical and functional tests revealed that laser therapy produced a string effect on the course of the illness. It reduced bleeding, inflammation, and pruritus. However, it did not produce an affect on electroexcitation. Biomicroscopic examinations and periodontium rheography revealed that the gingival blood flow became normal after the course of laser therapy. The capillary permeability and venous congestion decreased, which was confirmed by the increased time of vacuum tests, raised gingival temperature, reduced tissue clearance, and increased oxygen tension. Apart from that, laser therapy subsided fibrinolysis, proteolytic tissue activity, and decreased the exudative inflammation of periodontium.

    Background Several studies have reported an association between chronic periodontitis (CP) and cardiovascular diseases. Detection of periodontopathogens, including red complex bacteria (RCB), in vascular lesions has suggested these bacteria to be involved in the pathogenesis of atherosclerosis and abdominal aortic aneurysms. Objective In this study, we investigate bacteria and their DNA in vascular biopsies from patients with vascular diseases (VD; i.e. abdominal aortic aneurysms, atherosclerotic carotid, and common femoral arteries), with and without CP. Methods DNA was extracted from vascular biopsies selected from 40 VD patients: 30 with CP and 10 without CP. The V3-V5 region of the 16S rDNA (V3-V5) was polymerase chain reaction (PCR)-amplified, and the amplicons were cloned into Escherichia coli, sequenced, and classified (GenBank and the Human Oral Microbiome database). Species-specific primers were used for the detection of Porphyromonas gingivalis. In addition, 10 randomly selected vascular biopsies from the CP group were subjected to scanning electron microscopy (SEM) for visualization of bacteria. Checkerboard DNA–DNA hybridization was performed to assess the presence of RCB in 10 randomly selected subgingival plaque samples from CP patients. Results A higher load and mean diversity of bacteria were detected in vascular biopsies from VD patients with CP compared to those without CP. Enterobacteriaceae were frequently detected in vascular biopsies together with cultivable, commensal oral, and not-yet-cultured bacterial species. While 70% of the subgingival plaque samples from CP patients showed presence of RCB, only P. gingivalis was detected in one vascular biopsy. Bacterial cells were seen in all 10 vascular biopsies examined by SEM. Conclusions A higher bacterial load and more diverse colonization were detected in VD lesions of CP patients as compared to patients without CP. This indicated that a multitude of bacterial species both from the gut and the

    Background: Use of smokeless tobacco in the form of moist snuff placed in the oral cavity is popular in rural India. The aim of the present cross-sectional study was to determine the effect of snuff on periodontitis by assessing interleukin (IL)-1 β and IL-8 levels in gingival crevicular fluid. Materials and Methods: A total of 60 subjects were selected for this study. 40 subjects presented with periodontitis, which included 20 snuff users (SP) and 20 nonsnuff users (NS). 20 periodontally healthy patients formed the controls (healthy control: HC). The clinical parameters recorded were gingival index (GI), plaque index, calculus index, bleeding on probing (BOP), probing depth (PD), recession (RC), and clinical attachment level (CAL). The IL-1 β and IL-8 levels were assessed through enzyme-linked immunosorbent assay (Quantikine®). Analysis of variance (ANOVA), post-hoc Tukey's, Kruskal-Walli's ANOVA and Mann-Whitney test was used for comparison among groups and P > 0.05 was considered statistically significant. Results: No significant difference was seen in levels of IL-1 β and IL-8 between SP and NS groups (P = 0.16, 0.97). However, both the periodontitis groups (SP and NS) had increased IL-β levels when compared to HC group (P = 0.01, 0.001). The snuff users showed significant increase in GI, BOP, RC, and CAL when compared with NS (P = 0.002, 0.001, 0.012, 0.002) whereas NS group had significant increase in PD (P = 0.003). Conclusion: Within the limitations of this study, use of snuff does not affect the host inflammatory response associated with periodontitis and leads to RC and increased CAL due to local irritant effect.

    Gingivitis and chronic periodontitis are highly prevalent chronic inflammatory diseases. Gingivitis affects the majority of people, and advanced periodontitis is estimated to affect 5-15% of adults. The detection and diagnosis of these common diseases is a fundamentally important component of oral health care. All patients should undergo periodontal assessment as part of routine oral examination. Periodontal screening using methods such as the Basic Periodontal Examination/Community Periodontal Index or Periodontal Screening Record should be performed for all new patients, and also on a regular basis as part of ongoing oral health care. If periodontitis is identified, full periodontal assessment is required, involving recording of full mouth probing and bleeding data, together with assessment of other relevant parameters such as plaque levels, furcation involvement, recession and tooth mobility. Radiographic assessment of alveolar bone levels is driven by the clinical situation, and is required to assess bone destruction in patients with periodontitis. Risk assessment (such as assessing diabetes status and smoking) and risk management (such as promoting smoking cessation) should form a central component of periodontal therapy. This article provides guidance to the oral health care team regarding methods and frequencies of appropriate clinical and radiographic examinations to assess periodontal status, to enable appropriate detection and diagnosis of periodontal conditions.

    Background Obtaining high quality genomic DNA safely and economically is vital for diverse studies of large populations aimed at evaluating the role of genetic factors in susceptibility to disease. Aim This study was to test a protocol for the extraction of high quality genomic DNA from saliva samples obtained with mouthwash and taken from patients with periodontal disease. Methods Saliva samples were taken from 60 patients and then stored at room temperature. DNA extraction was carried out at distinct post-sampling times (10, 20 and 30 days). Evaluation of genomic DNA was performed with spectrophotometry, electrophoresis, and PCR genotyping and sequencing. Results The greatest concentration of DNA obtained was 352 μg at 10 days post-sampling, followed by 121.025 μg and 19.59 μg at 20 and 30 days, respectively. When determining the purity of DNA with the spectrophotometric ratio of 260/230, the relations of 1.20, 1.40 and 0.781 were obtained for 10, 20 and 30 days, respectively. In all samples, it was possible to amplify the product of 485 bp and the sequence of the amplicons showed 95% similarity to the reference sequence. Conclusion The present protocol represents an easy, safe and economical technique for obtaining high quality genomic DNA. PMID:27195211

    Volume reduction and functional impairment in areas of the prefrontal cortex (PFC) have been found in borderline personality disorder (BPD), particularly in patients with a history of childhood abuse. These abnormalities may contribute to the expression of emotion dysregulation and aggressiveness. In this study we investigated whether the volume of the PFC is reduced in BPD patients and whether a history of childhood abuse would be associated with greater PFC structural changes. Structural MRI data were obtained from 18 BPD patients and 19 healthy individuals matched for age, sex, handedness, and education and were analyzed using voxel based morphometry. The Child Abuse Scale was used to elicit a past history of abuse; aggression was evaluated using the Buss-Durkee Hostility Inventory (BDHI). The volume of the right ventrolateral PFC (VLPFC) was significantly reduced in BPD subjects with a history of childhood abuse compared to those without this risk factor. Additionally, right VLPFC gray matter volume significantly correlated with the BDHI total score and with BDHI irritability and negativism subscale scores in patients with a history of childhood abuse. Our results suggest that a history of childhood abuse may lead to increased aggression mediated by an impairment of the right VLPFC.

    Aim: Vitamin D is associated with inflammatory diseases such as periodontal disease and diabetes mellitus (DM). The aim of our study was to find out the level of serum Vitamin D in chronic periodontitis patients (CHP) with and without type 2 DM. Materials and Methods: This study consists of 141 subjects, including 48 controls. Case groups consisted of 43 chronic periodontitis patients with type 2 DM (CHPDM) and 50 CHP. pocket depth (PD), clinical attachment loss (CAL), modified gingival index (MGI), plaque index (PI), and calculus index (CI) were taken. Serum 25-hydroxyvitamin D (25[OH] D) level in ηg/ml was estimated by electrochemiluminescence immunoassay with Elecsys and cobase e immunoassay analysers(cobase e 411). Other laboratory investigations including fasting blood sugar (FBS) and serum calcium were measured in all subjects. Results: The mean serum 25(OH) D level was 22.32 ± 5.76 ηg/ml, 14.06 ± 4.57 ηg/ml and 16.94 ± 5.58 ηg/ml for control, CHPDM and CHP groups respectively. The difference was statistically significant (P < 0.05). The mean value of FBS was significantly high in CHPDM group as compared to CHP group. Periodontal parameters like MGI, PI, PD, and CI showed significant difference between groups (P < 0.05) and higher score was found in CHP group, while CAL and PI showed no statistically significant difference between CHP and CHPDM group (P > 0.05). Conclusions: This study observed a low level of serum Vitamin D level in patients with CHP and CHPDM. Low Vitamin D level was observed in case groups may be due to the diseases process rather than low Vitamin D acting as a cause for the disease. PMID:26644714

    Background Dental caries and Periodontal diseases are the most prevalent oral health problems present globally. The distribution and severity of such oral health problems varies in different parts of the world and even in different regions of the same country. Nepal is one of the country with higher prevalence rate of these problems. These problems arise in association with multiple factors. Objective This study was carried out to describe the periodontal status and to analyse the association of periodontal disease with the wearing of fixed or removable partial dentures in a Nepalese population reporting to the College of Dental Surgery, B P Koirala Institute of Health Sciences, Dharan, Nepal. Method This study comprised of a sample of 200 adult individuals. All data were collected by performing clinical examinations in accordance with the World Health Organization Oral Health Surveys Basic Methods Criteria. It included the Community Periodontal Index and dental prosthesis examination. Result A descriptive analysis was performed and odds ratio (1.048) and 95% confidence interval (1.001; 1.096) was found out. The mean age of the population participated in the study was 41.82 ± 14.80 years. A total of 93 (46.5%) males and 107 (53.5%) females participated in the study. Among these subjects, 100% presented some periodontal problems. The statistical analysis indicated that the probability of periodontal disease with regards to wearing partial dentures was not significant as suggested by the odds ratio (1.048). Conclusion There is no association of the wearing of dental prosthesis (RPD and/or FPD) with the periodontal disease and suggests a need for populations based oral health education programs, plaque control programs to reduce the incidence of periodontal disease.

    Benign by nature, aggressive fibromatoses (desmoid fibromas) may represent as difficult therapeutic problems as malignant tumours. When subtotally resected they tend to recur. But spontaneous regression is possible. Expense and limits of their surgical treatment are discussed with reference to seven patients. In five cases primary affliction of bone was evident. There are three reports given in detail: In the first, malignant transformation may be due to radiation therapy and hemipelvectomy could not prevent recurrence. In the second, spontaneous regression of untreated pelvic affection may have occurred. In the third, several resections and amputation of the leg failed to cure congenital infantile fibromatosis.

    Von Willebrand's disease is a genetic bleeding disorder characterized by either a reduced plasma concentration of von Willebrand's factor (vWF) or a qualitative deficiency in that vWF which is produced. Previous therapy consisted of injecting concentrates of vWF manufactured from the pooled plasma of multiple donors. With the increased incidence and risk of serum borne transmission of such diseases as hepatitis and AIDS, the advantages of an alternative mode of therapy was obvious. In the course of using 1-desamino-8-D-arginine (desmopressin or DDAVP, a synthetic analogue of 8-arginine vasopressin, a hormone secreted in the posterior pituitary gland) in the treatment of diabetes insipidus, it was discovered that this drug causes the release of bound vWF into the plasma. The elevation lasts for several hours and is effective in producing hemostasis in some types of mild to moderate von Willebrand's disease. In 1984, desmopressin was approved for this usage in the United States. This paper discusses the use of DDAVP in the management of von Willebrand's disease and present two case reports of patients with von Willebrand's disease and in need of periodontal surgery.

    Substantial ongoing research continues to explore the contribution of genetics and environment to the onset, extent and severity of periodontal disease(s). Existing evidence supports that periodontal disease appears to have an increased prevalence in family units with a member having aggressive periodontitis. We have been using the nonhuman primate as a model of periodontal disease for over 25 years with these species demonstrating naturally occurring periodontal disease that increases with age. This report details our findings from evaluation of periodontal disease in skulls from 97 animals (5-31 years of age) derived from the skeletons of the rhesus monkeys (Macaca mulatta) on Cayo Santiago. Periodontal disease was evaluated by determining the distance from the base of the alveolar bone defect to the cemento-enamel junction on 1st/2nd premolars and 1st/2nd molars from all four quadrants. The results demonstrated an increasing extent and severity of periodontitis with aging across the population of animals beyond only compensatory eruption. Importantly, irrespective of age, extensive heterogeneity in disease expression was observed among the animals. Linking these variations to multi-generational matriarchal family units supported familial susceptibility of periodontitis. As the current generations of animals that are descendants from these matrilines are alive, studies can be conducted to explore an array of underlying factors that could account for susceptibility or resistance to periodontal disease.

    Background The present clinical trial study was designed to assess the effect of topical application of melatonin on serum levels of tumor necrosis factor-alpha (TNF-α), interleukin-6 (IL-6) and C-reactive protein (CRP) in patients with diabetes and periodontal disease in comparison with healthy controls. Material and Methods Serum levels of TNF-α and IL-6 were measured by enzyme-linked immunosorbent assay and CRP by nephelometry by using the proper commercial kits in 30 patients with diabetes and periodontal disease, and also in a control group of 30 healthy subjects. Periodontograms were performed using the Florida Probe®. Patients with diabetes were treated with a topical application of melatonin (1% orabase cream formula) once daily for 20 days. Healthy subjects were treated with a placebo orabase cream. Results Patients with diabetes and periodontal disease had significantly higher mean levels of serum TNF-α, IL-6 and CRP than healthy subjects (P < 0.001). Following topical melatonin application, there was a statistically significant decrease in the gingival index and pocket depth (P < 0.001) as well as a significant decrease in IL-6 and CRP serum levels (P < 0.001). Local melatonin application in patients with diabetes and periodontal disease resulted in a significant decrease in CRP and IL-6 serum levels as well as an improvement in the gingival index and pocket depth. Patients with periodontal disease had significantly higher serum CRP, IL-6 and TNF-α values by comparison with healthy subjects. Conclusions We conclude that melatonin can modulate the inflammatory action of these molecules in periodontal patients. Key words:Melatonin, periodontal disease, diabetes mellitus, interleukin-6, tumor necrosis factor-alpha, C-reactive protein, inflammatory markers. PMID:26644840

  13. Fibrinogen Degradation Products and Periodontitis: Deciphering the Connection

    PubMed Central

    2015-01-01

    Introduction Fibrinogen degradation products (e.g. D-dimer) arise from digested fibrin clots and fibrinogen. Elevated concentrations accompany activation of coagulation and fibrinolysis and indicate chronic inflammatory diseases. D-Dimer tests are a quick, noninvasive method to rule out abnormal clotting. Periodontitis strongly affects the haemostatic system and evokes a procoagulant state. Correlation of chronic periodontitis with early indicators of disease (biomarkers) might be useful. Aim The aim of the study was to examine whether the plasma D-dimer concentration reflects the progression of chronic periodontitis and the beneficial effect of periodontal therapy. Materials and Methods Forty randomly selected subjects were divided into four groups, Group I: 10 healthy subjects, Group II: 10 with mild periodontitis, Group III: 10 with moderate periodontitis, Group IV: 10 with severe periodontitis. After thorough dental and periodontal examination, 3 mL of venous blood was collected for measurement of fibrinogen degradation products. Results The patients with moderate and chronic periodontitis exhibited high concentrations of D-dimer (mean value 434.98–535.52 mcg/mL), whereas subjects with mild or no periodontitis exhibited values of 329.78–211.29 mcg/mL. Concentrations of D-dimer were significantly reduced after therapy of all classes of periodontitis. Conclusion Periodontal treatment can reduce amount of D-dimer in the plasma. A higher than normal concentration is observed in chronic periodontitis. PMID:26816985

    Periodontal health is influenced by a number of factors such as oral hygiene, genetic and epigenetic factors, systemic health, and nutrition. Many studies have observed that a balanced diet has an essential role in maintaining periodontal health. Additionally, the influences of nutritional supplements and dietary components have been known to affect healing after periodontal surgery. Studies have attempted to find a correlation between tooth loss, periodontal health, and nutrition. Moreover, bone formation and periodontal regeneration are also affected by numerous vitamins, minerals, and trace elements. The aim of this review is to critically appraise the currently available data on diet and maintenance of periodontal health and periodontal healing. The effects of nutritional intervention studies to improve the quality of life and well-being of patients with periodontal disease have been discussed. PMID:27589794

    This report introduces the nursing caring experience with a male patient with frontotemporal dementia (FTD) who was hospitalized in an acute psychiatric ward from March 5th to April 30th, 2012 due to the clinical manifestations of verbally expressive impairment, aggression, and subsequent caregiver burden. The patient was assessed according to the guidelines of clinical competencies for mental health nursing assessments developed by the Psychiatric Mental Health Nurses Association. Three clinical diagnoses were identified after this assessment, including (1) impaired verbal communication, (2) chronic confusion, and (3) caregiver role strain. The current report focuses only on the clinical issue of impaired verbal communication. We adopted a props-integrated communicative approach by integrating props and physical motions with communicative strategies. This approach enabled us to formulate a patient-centered communicating model and prompt for active expression and adequate communication, which ultimately resolved the patient's aggression problem. In addition, we provided psychoeducation to the family members in order to teach them the relevant knowledge, skills, and approaches that caregivers may use to enhance their caring capabilities and reduce the burden of caregiving. This successful experience may be used as a reference in caring for FTD patients with communicative impairments. Our proposed approach integrates props with simple language and develops an appropriate communicating model to provide high quality care for patients.

    Background: It is suggested that diabetes plays an important role in tooth loss. The periodontal structure and alveolar bone architecture in diabetics have revealed alterations. However, changes in cementum of diabetics with periodontal disease have not been evaluated adequately. Thus, the aim of the study is to evaluate and compare the thickness of cementum in diseased and healthy areas of roots of teeth with chronic periodontitis from non-diabetic (group I) and type 2 diabetic patients (group II). Materials and Methods: Thirty incisors indicated for extraction as a result of chronic periodontitis from group I and group II were selected. Measurements of Probing Depth (PD) and Clinical Attachment Loss (CAL) were taken prior to extractions. Area of the root surface above the CAL (notch) was designated as diseased, while the area below the CAL (notch) was designated as healthy. The extracted tooth samples were sectioned longitudinally and were evaluated by scanning electron microscopy (SEM). Descriptive statistical analysis was performed. Results of continuous measurements were presented as Mean ± SD. Results: The results showed that in both groups the thickness of cementum in diseased areas was lower in comparison to the thickness in healthy areas. The mean thickness of cementum in both healthy and diseased areas was higher in group II compared to group I, though the differences in both were not statistically significant. Conclusion: Within the limits of the present study, group II showed greater mean thickness of cementum in both healthy and diseased areas compared to group I, though the differences were not statistically significant.

    Neutrophil chemotaxis was evaluated in nine patients with juvenile periodontitis, with normal subjects and patients with the adult form of periodontitis as controls. Defective chemotactic responses were observed in neutrophils from seven of nine juvenile patients, and a reduced level of complement-derived chemotactic activity was demonstrated in serum from four patients. These determinations were normal in all the patients with adult periodontitis. Serum from five of the juvenile patients contained a heat-stable, non-dialyzable factor that markedly inhibited the chemotaxis of normal neutrophils. Thus the characteristic tissue destruction seen in juvenile periodontitis may be, at least in part, a consequence of a failure of host defense mechanisms. PMID:591063

    Minimally invasive dentistry is a concept that preserves dentition and supporting structures. However, minimally invasive procedures in periodontal treatment are supposed to be limited within periodontal surgery, the aim of which is to represent alternative approaches developed to allow less extensive manipulation of surrounding tissues than conventional procedures, while accomplishing the same objectives. In this review, the concept of minimally invasive periodontal surgery (MIPS) is firstly explained. An electronic search for all studies regarding efficacy and effectiveness of MIPS between 2001 and 2009 was conducted. For this purpose, suitable key words from Medical Subject Headings on PubMed were used to extract the required studies. All studies are demonstrated and important results are concluded. Preliminary data from case cohorts and from many studies reveal that the microsurgical access flap, in terms of MIPS, has a high potential to seal the healing wound from the contaminated oral environment by achieving and maintaining primary closure. Soft tissues are mostly preserved and minimal gingival recession is observed, an important feature to meet the demands of the patient and the clinician in the esthetic zone. However, although the potential efficacy of MIPS in the treatment of deep intrabony defects has been proved, larger studies are required to confirm and extend the reported positive preliminary outcomes.

    Aim: To study the efficacy of a noninjectable anesthetic gel with a thermosetting agent in the reduction of pain during scaling and root planing (SRP) in untreated chronic periodontitis patients. Materials and Methods: This study is a randomized, double-masked, split-mouth, placebo-controlled trial. Thirty patients were enrolled who underwent SRP in a split-mouth (right side/left side) manner. Before commencement of SRP, both quadrants on each side were isolated and had a randomized gel (either placebo or test gel) placed in the periodontal pockets for 30 s. The pain was measured using numerical rating scale (NRS) and verbal rating scale (VRS). Results: The median NRS pain score for the patients treated with the anesthetic test gel was 1 (range: 0-4) as opposed to 5 (range: 3-7) in the placebo treated patients. The mean rank of pain score using NRS in test gel was 16.18 as compared to 44.82 in placebo treated sites. Hence, significant reduction in pain was found in test gel as compared to placebo using NRS (P < 0.001). The VRS showed that the majority of patients reported no pain or mild pain with a median of 1 as compared to placebo treated sites with a median of 2 suggestive of moderate pain. Conclusions: The NRS and VRS pain scores showed that the side treated with anesthetic gel was statistically more effective than the placebo in reducing pain during SRP. PMID:27051372

    The clinical and histological appearance of gingiva was evaluated in renal transplant recipients (RTR) receiving immunosuppressive drugs, in patients with chronic renal failure (CRF) undergoing hemodialysis, and systemically healthy individuals with periodontitis. Although the amount of bacterial plaque accumulation was similar among the groups (P greater than 0.05), the gingival inflammation was significantly less in RTR when compared to the other 2 groups (P less than 0.05). In light microscopic investigation the overall appearance of the connective tissue was similar in all of the groups. A mononuclear cell infiltration was present in all of the specimens; however, the number of inflammatory cells in patients with periodontitis was significantly higher than the other 2 groups (P less than 0.05). Prominent epithelial changes in the superficial layers of the oral epithelium; i.e., areas showing desquamation-like appearance, were noticed in patients with CRF. In electron microscopic investigation, fibroblasts and plasma cells with well-developed granular endoplasmic reticulum were found in connective tissue in RTR patients. In patients with CRF, epithelial cells presented swollen granular endoplasmic reticulum cisternae resembling vacuoles, indicating the presence of degeneration. It was suggested that with the use of immunosuppressive drugs the response to bacterial plaque did not diminish completely. PMID:1765936

    The aim of the study was to evaluate the effect of combined use of Cytoflavin and cognitive therapy on the dynamics of psychosomatic status and effectiveness of the treatment of generalized periodontitis in elderly patients. The results of treatment of 103 patients aged 60 and older were analyzed. All patients received standard therapy for 10-14 days depending on the severity of the process. In addition, the patients of the main group (51 patients) received Cytoflavin: 2 tabs. 2 times a day with an interval between doses of 8-10 hours for 25 days, and cognitive therapy aimed at training alternative realistic way of life perception. Treatment results were monitored by PMA, Russell periodontal index (PI), Green-Vermillion hygienic index. Psychosomatic dynamics was assessed by means of Spielberger anxiety scale and SUN" methods of before and after a month of treatment. The inclusion in the treatment regimen of Cytoflavin and cognitive therapy had a positive impact: reduction of PMA by 61.8%, PI by 45.3% and Green-Vermillion index by 39.8%. The psychosomatic tests proved anxiety level decrease by 28.7% in terms of "reactive" anxiety and 31.5% in terms of "personal" anxiety, emotional status (21.2%), activity (21.7%) and mood (21.8%) improvement.

    Aims and Objective: This study was conducted to evaluate the effect of hydrogen peroxide (H2O2) as a mouthwash in comparison with chlorhexidine (CHX) in chronic periodontitis patients. Materials and Methods: A total of 45 patients suffering from localized mild to moderate chronic periodontitis were chosen. The subjects were divided equally into three groups. Group A patients were treated only with scaling and root planning (SRP). Group B were treated with SRP in combination with 0.2% CHX gluconate mouthwash twice daily for 10 days. Group C were treated with SRP in combination with 1.5% H2O2 mouthwash twice daily for 10 days. Gingival index, plaque index, pocket depth, and clinical attachment level were recorded for patients of all groups on day 0 (Baseline), 15, 30, and 90, respectively. Statistical analysis was done using the Statistical Package for the Social Sciences version 22.0. Repeated measures analysis of variance was used to assess the differences in the abovementioned indices because of time and groups. Results: Both CHX gluconate and H2O2 mouthwashes significantly reduced the gingival index more than that observed in the control group, but similar to each other. There were no significant differences in the clinical attachment loss, plaque index, and pocket depth among the study groups, but improvement was seen within the CHX group participants. In participants with chronic periodontitis, SRP in combination with 0.2% CHX gluconate mouthwash was an effective treatment in reducing the gingival index and the pocket depth, as well as improving the clinical attachment level. Conclusion: The use of CHX gluconate was observed to be higher than H2O2 for the reduction in the gingival index and the pocket depth, as well as for the improvement of the clinical attachment level.

    The acute phase of chronic periodontitis may occur even in patients during supportive periodontal therapy. However, the details are not fully understood. Since the natural environment, including meteorology affects human health, we hypothesized that weather conditions may affect occurrence of acute phase of chronic periodontitis. The aim of this study was to investigate the relationship between weather conditions and acute phase of chronic periodontitis in patients under supportive periodontal therapy. Patients who were diagnosed with acute phase of chronic periodontitis under supportive periodontal therapy during 2011–2013 were selected for this study. We performed oral examinations and collected questionnaires and meteorological data. Of 369 patients who experienced acute phase of chronic periodontitis, 153 had acute phase of chronic periodontitis without direct-triggered episodes. When using the autoregressive integrated moving average model of time-series analysis, the independent covariant of maximum hourly range of barometric pressure, maximum hourly range of temperature, and maximum daily wind speed were significantly associated with occurrence of acute phase of chronic periodontitis (p < 0.05), and 3.1% of the variations in these occurrence over the study period were explained by these factors. Meteorological variables may predict occurrence of acute phase of chronic periodontitis. PMID:26251916

    Supernatants from gingival fibroblast cultures obtained from 14 patients with periodontal disease contained factor(s) capable of stimulating bone resorption in vitro, as assessed by the release of 45Ca from neonatal mouse calvariae. The possibility that the factor(s) was interleukin-1 alpha (IL-1 alpha), IL-1 beta or prostaglandin E2 (PGE2) was next investigated. The human fibroblast conditioned media (HFCM) stimulated PGE2 biosynthesis in bone. The stimulatory effect by HFCM on 45Ca release, however, was not affected by blocking prostaglandin biosynthesis with indomethacin. In contrast, 45Ca release induced by IL-1 alpha, IL-1 beta, thrombin and bradykinin was significantly reduced by indomethacin, whereas the effects of PTH and PTHrP were unaffected by indomethacin. The concentration of PGE2 in HFCM was too low to be solely responsible for the 45Ca release response. In addition, the amount of bone resorbing activity produced by the gingival fibroblasts was unaffected by cyclo-oxygenase inhibitors. Similar to IL-1 alpha and IL-1 beta, the stimulatory effect of HFCM was inhibited by gamma-interferon. HFCM did not stimulate cyclic AMP formation in the mouse calvarial bones. Antisera which specifically blocked human IL-1 alpha or IL-1 beta induced 45Ca release, and the specific IL-1 receptor antagonistic protein, did not inhibit the stimulatory effect of HFCM. These data show that gingival fibroblasts secrete bone resorbing factor(s) which is not due to IL-1 and which stimulates bone resorption by a prostaglandin- and cyclic AMP-independent mechanism.

    Reconstruction of missing papilla--the basis of modern concepts of objective treatment of dental diseases. Interproximal spaces are important anatomical structures, as are bulky in the mouth and repeated many times. Violation of relations between different structural elements increases the risk of inflammation in periodontitis. Patients with approximal caries posteriors and generalized periodontitis studied anthropometric parameters of the structures of the interdental spaces and their impact on the volume papilla before and after restoration, carried out with move a contact point to the apex. The results showed that the relationship between anthropometric data interdental had certain patterns in all groups surveyed. Important was a clear relationship between anthropometric indicators of basic elements of interdental spaces. In the absence of the interproximal papilla length (IPL) was on average 7.2 mm, the distance from the gingival margin to the proximal contact--3.9 mm and the horizontal distance between the roots at the enamel--cement border (HDR) reached 3.2 mm. Following the restoration with move a contact point to the apex to an average of 4.5 mm IPL, there was a significant increase in the interdental papillae. In the case of patients prior to treatment was determined by a thin biotype, the small width of attached gingival significant HDR--volume papilla week after restorations movement of the contact point to the root apex contact point is not increased. The results obtained require long-term studies for the possibility of forecasting the success of the restoration or preservation of the interdental papillae in the restoration of approximal cavities on the stages of rehabilitation of patients with generalized periodontitis.

There is a moderate association of periodontitis with adverse pregnancy outcomes and rheumatoid arthritis. Periodontal treatment has, on average, a positive effect on reducing systemic infection and improving the condition of the vascular system. For diabetes patients, periodontal treatment can also have a positive effect on metabolic regulation. There is insufficient evidence that periodontal treatment prevents adverse pregnancy outcomes and rheumatoid arthritis. PMID:26465017

    Background Hepatitis C virus (HCV) is mainly transmitted by parenteral route, being blood transfusion and intravenous drug use the most frequent risk factors. However, it has been suggested that there are other routes of transmission. There are several studies where HCV RNA has been detected in saliva of patients infected with HCV, and epidemiological studies have proposed the dental treatments as possible risk factors for HCV transmission. The purpose of this study was to detect the presence of HCV RNA in saliva of patients with active infection and associating with periodontal or liver disease. Methods Patients with quantifiable HCV-RNA in serum were enrolled in the study. Periodontal disease was assessed using the modified gingival index (MGI). Presence of dental plaque was assessed with the use of disclosing tablets. Patients were clinically and laboratory evaluated to identify the stage of liver disease, the HCV RNA was determinate in saliva by nested RT-PCR. To determine associations between different parameters univariate and multivariate analysis were used. Results A total of 45 patients were included. Of these patients, 21 (46.6%) had hepatitis, 23 (51.1%) had cirrhosis and one patient (2.4%) presented hepatocellular carcinoma (HCC). Viral loads in serum ranged from 2.31–6.68 log IU/ml with a mean of 5.46 log IU/ml (95% CI 5.23–5.70). HCV RNA was positive in saliva of 29 patients (64.4%) and was not detected in 16 (35.6%). For univariate analysis three independent variables were associated with the detection of HCV-RNA in saliva: gender, viral load and dental plaque and multivariate analysis only one independent variable viral load >5.17 log IU/mL remained significantly associated with the detection of HCV in saliva (p = 0.0002). A statistical difference was observed when viral load was analyzed, log 5.85 IU/mL (95% CI 5.67–6.02) for patients with HCV in saliva vs. log 4.77 IU/mL (95% CI 4.35–5.19) for patients without HCV in saliva (p

    Periodontitis is a complex immune-inflammatory disease that results from a preestablished infection in gingiva, mainly due to Gram-negative bacteria that colonize deeper in gingival sulcus and latter periodontal pocket. Host inflammatory and immune responses have both protective and destructive roles. Although cytokines, prostaglandins, and proteases struggle against microbial burden, these molecules promote connective tissue loss and alveolar bone resorption, leading to several histopathological changes, namely destruction of periodontal ligament, deepening of periodontal pocket, and bone loss, which can converge to attain tooth loss. Despite the efforts of genomics, transcriptomics, proteomics/peptidomics, and metabolomics, there is no available biomarker for periodontitis diagnosis, prognosis, and treatment evaluation, which could assist on the established clinical evaluation. Nevertheless, some genes, transcripts, proteins and metabolites have already shown a different expression in healthy subjects and in patients. Though, so far, ‘omics approaches only disclosed the host inflammatory response as a consequence of microbial invasion in periodontitis and the diagnosis in periodontitis still relies on clinical parameters, thus a molecular tool for assessing periodontitis lacks in current dental medicine paradigm. Saliva and gingival crevicular fluid have been attracting researchers due to their diagnostic potential, ease, and noninvasive nature of collection. Each one of these fluids has some advantages and disadvantages that are discussed in this review. PMID:24828325

    Diabetes mellitus is a group of metabolic diseases characterized by hyperglycemia resulting from defects in insulin secretion, a defect in insulin action or a combination of both. Periodontitis is now considered a chronic localized infection of the oral cavity that can trigger inflammatory host immune responses at local and systemic levels, and can also be a source of bacteremia. It is now known that periodontitis has an influence on the pathogenesis of certain systemic diseases. The biological relationship between diabetes and periodontal disease is well documented. In the mid-90s sufficient scientific support for the association between diabetes and periodontitis was published, and periodontitis was designated as the sixth complication of diabetes. There have been studies that show an improvement in both clinical and immunological parameters of periodontitis and glycemic control in long-term diabetes after treatment of periodontal disease. In addition, scientific evidence confirms that poorer glycemic control contributes to a worse periodontal condition. The interplay between the 2 conditions highlights the importance of the need for a good communication between the internist and dentist about diabetic patients, considering always the possibility that the 2 diseases may be occurring simultaneously in order to ensure an early diagnosis of both.

    Talking about periodontic-orthodontic interrelationships is related primarily to the 1960s, where a generalized increase in salivary bacterial counts, especially Lactobacillus, had been shown after orthodontic band placement. The purpose of this article is to provide the dental practitioner with basic understanding of the interrelationship between periodontics and orthodontics by means of representing classical studies, and, to give an update on this topic by demonstrating the most recent opinions concerning periodontic-orthodontic interrelationships. Specific areas reviewed are the ability of orthodontic treatment to afford some degree of protection against periodontal breakdown, short-term and long-term effects of orthodontic treatment on the periodontium, and some mucogingival considerations. Topics considering orthodontic treatment in periodontally compromised patients were not included in this review. While past studies have shown that orthodontic treatment can positively affect the periodontal health, recent reviews indicate an absence of reliable evidence for the positive effects of orthodontic therapy on patients’ periodontal status. Periodontic-orthodontic interrelationships are still controversial issues. However, a standard language between the periodontist and the orthodontist must always be established to eliminate the existing communications barrier, and to improve the outcomes of the whole treatment.

    2016-06-01

    This review gives an update of the current scientific evidence on the efficacy of the adjunctive use of systemic and local antibiotics/antimicrobials in the treatment of periodontitis. In particular, it addresses whether their use can improve the results of nonsurgical mechanical therapy in mild-to-moderate forms of the disease. Large numbers of randomized clinical trials and systematic reviews with meta-analyses have clearly established that adjunctive systemic antibiotics, combined with mechanical debridement, offer clinical improvements additional to those obtained with scaling and root planing alone. These effects are more pronounced in aggressive periodontitis and in initially deep pockets, whereas more limited additional improvements, of 0.3 mm for additional pocket reduction and 0.2 mm for additional clinical attachment gain, have been documented for moderately deep sites (4-6 mm) in patients with chronic periodontitis. The marginal clinical benefit in patients with moderate disease has to be balanced against possible side effects. Notably, it has to be realized that an increasing number of warnings have been articulated against the unrestricted use of antibiotics in treating periodontal diseases because of the emerging global public health issue of bacterial resistance. The effects of the adjunctive local administration of antimicrobials have also been very well documented in several systematic reviews. Overall, in persistent or recurrent localized deep sites, the application of antimicrobials by sustained-delivery devices may offer a benefit of an additional 0.4 mm in pocket depth reduction and 0.3 mm in clinical attachment level gain. In conclusion, the slight additional benefits of adjunctive antimicrobials, which were shown for moderate forms of periodontitis, have to be balanced against their side effects and therefore their prescription should be limited as much as possible.

    1995-10-01

    This study was performed to assess the influence of smoking on periodontal disease severity. Data concerning periodontal status and smoking habits were collected from 889 periodontal patients: 340 male and 549 female, 21 to 76 years of age, 47.4% being non smokers and 52.6% smokers. Periodontal parameters, recorded by the same examiner (PMC), were: gingival recession (GR), Pocket depth (PD), Probing attachment level (PAL), and mobility (M). The influence of age, sex and tobacco consumption on these periodontal parameters was statistically evaluated using an analysis of variance (ANOVA) with covariates. A non-linear effect model was also fitted by taking the natural logarithms of the response variables (GR, PD, PAL) closer to biomedical phenomena. Mobility was analyzed by a chi2-test. The effect of smoking on periodontitis showed no association with age or with sex. Smoking, age and sex were shown to be statistically significant for periodontitis, by performing both univariate (t-test for equal means) and multivariate tests. p-values for smoking and periodontitis were: GR (p=0.000), PD (p=0.000), PAL (p=0.000) and M (P=0.015). Smoking one cigarette per day, up to 10, and up to 20, increased PAL by 0.5%, 5% and 10%, respectively. The impact of tobacco is comparable to the impact resulting from the factor of age in this sample, increasing PAL by 0.7% for each year of life. Comparison between smokers of less than 10 cigarettes per day (PAL mean 3.72 mm +/-0.86) and non-smokers (PAL mean 3.84 +/- 0.89) showed no differences in PAL (p=0.216), while comparison for smokers from 11 to 20 cigarettes (PAL mean 4.36 +/- 1.23) and for more than 20 cigarettes (PAL mean 4.50 +/- 1.04) demonstrated significant differences (p=0.000). These findings suggest that: (1) tobacco increases periodontal disease severity; (2) this effect is clinically evident above consumption of a certain quantity of tobacco.

    Objectives: The aim of this study was to determine the prevalence of the different fimA genotypes of Porphyromonas gingivalis in adult Spanish patients with chronic periodontitis, patients with gingivitis and periodontally healthy subjects, and the relationship between these genotypes and other periodontopathogenic bacteria. Study design: Samples of subgingival plaque were taken from 86 patients (33 with chronic periodontitis, 16 with gingivitis, and 37 periodontally healthy) in the course of a full periodontal examination. PCR was employed to determine the presence of the 6 fimA genotypes of Porphyromonas gingivalis (I-V and Ib) and of Aggregatibacter actinomycetemcomitans, Tannerella forsythia and Treponema denticola. Results: Porphyromonas gingivalis fimA genotypes II and Ib were present in significantly higher percentages in periodontal patients (39.4% and 12.1% respectively) than in healthy or gingivitis subjects. The prevalence of Tannerella forsythia, Treponema denticola, and Porphyromonas gingivalis fimA genotype IV was significantly higher in the group that presented bleeding greater than 30%. A positive correlation was found between Porphyromonas gingivalis fimA genotype IV and Treponema denticola. Conclusions: A strong association between Porphyromonas gingivalis fimA genotypes II and Ib and chronic periodontitis exists in the Spanish population. The most prevalent genotype in periodontal patients is II. Key words:Periodontitis, Porphyromonas gingivalis, fimA genotype, periodontal bacteria, polymerase chain reaction. PMID:22549664

    Oral hygiene experiments with H2O2 and chlorhexidine rinsing were performed in 15 patients with dental splints for jaw fractures and intermaxillary wiring. To measure the various cleaning measures, Löe's plaque index (1967) was determined at the 7th, 21st, and 35th postoperative days. The 2% chlorhexidine gluconate was always by far superior to H2O2 as far as plaque inhibition was concerned. With chlorhexidine plaque reduction up to 69% and H202 reductions up to 22% were observed. After a test period of about 5 weeks, only slight side-effects were recorded, such as discolorations at the lingual side of the teeth and in few cases bad taste or dark coating of the tongue.

    Purpose: To evaluate the response rate (RR) and time to local recurrence (TTLR) among patients who received salvage radiation therapy for relapsed or refractory aggressive non-Hodgkin lymphoma (NHL) and investigate whether RR and TTLR differed according to disease characteristics. Methods and Materials: A retrospective review was performed for all patients who completed a course of salvage radiation therapy between January 2001 and May 2011 at Brigham and Women's Hospital/Dana-Farber Cancer Institute. Separate analyses were conducted for patients treated with palliative and curative intent. Predictors of RR for each subgroup were assessed using a generalized estimating equation model. For patients treated with curative intent, local control (LC) and progression-free survival were estimated with the Kaplan-Meier method; predictors for TTLR were evaluated using a Cox proportional hazards regression model. Results: Salvage radiation therapy was used to treat 110 patients to 121 sites (76 curative, 45 palliative). Salvage radiation therapy was given as part of consolidation in 18% of patients treated with curative intent. Median dose was 37.8 Gy, with 58% and 36% of curative and palliative patients, respectively, receiving 39.6 Gy or higher. The RR was high (86% curative, 84% palliative). With a median follow-up of 4.8 years among living patients, 5-year LC and progression-free survival for curative patients were 66% and 34%, respectively. Refractory disease (hazard ratio 3.3; P=.024) and lack of response to initial chemotherapy (hazard ratio 4.3; P=.007) but not dose (P=.93) were associated with shorter TTLR. Despite doses of 39.6 Gy or higher, 2-year LC was only 61% for definitive patients with refractory disease or disease that did not respond to initial chemotherapy. Conclusions: Relapsed or refractory aggressive NHL is responsive to salvage radiation therapy, and durable LC can be achieved in some cases. However, refractory disease is associated with a shorter

    Aim The aim of the present randomized, double blind, parallel, 2-arm clinical study was to examine the safety and efficacy of frequent applications of chlorhexidine chip (CHX) and flurbiprofen chip (FBP) in patients with chronic periodontitis. Methods Sixty patients were randomized into CHX and FBP groups. Following OHI and scaling and root planing (SRP), baseline pocket depth (PD) measurements, gingival recession and bleeding on probing (BOP) were performed and repeated at week 4 and 8. The assigned chip was placed at weeks 0, 1, 2, 3, 5, 7. Results Mean PD reduction in the CHX group was 2.08 mm (7.17 to 5.09, p < 0.0001). Mean PD reduction in the FBP group was 2.27 mm (6.72 to 4.45, p < 0.0001). Ninety-seven percentage and 95% of these sites exhibited PD reduction ≥1 mm, while 38% and 34% of the sites exhibited PD ≥3 mm (FBP and CHX, respectively). Clinical attachment level gain (1.66 and 1.95 mm, respectively) was statistically significant (p < 0.0001). Baseline BOP dropped from 98% and 100% to 24% and 30% for the CHX and FBP groups, respectively (p < 0.0001). Conclusion Frequent applications of CHX and FBP chips resulted in a significant improvement in the periodontal condition in these sites. Furthermore studies will be required to compare this new treatment regimen to SRP or SRP with single chip application. PMID:22092475

    Gingivitis and periodontitis are immunoinflammatory periodontal diseases characterized by chronic localized infections usually associated with insidious inflammation This narrative review discusses periodontal diseases and mechanisms influencing the immune response and autoimmunity in pediatric rheumatic diseases (PRD), particularly juvenile idiopathic arthritis (JIA), childhood-onset systemic lupus erythematosus (C-SLE) and juvenile dermatomyositis (JDM). Gingivitis was more frequently observed in these diseases compared to health controls, whereas periodontitis was a rare finding. In JIA patients, gingivitis and periodontitis were related to mechanical factors, chronic arthritis with functional disability, dysregulation of the immunoinflammatory response, diet and drugs, mainly corticosteroids and cyclosporine. In C-SLE, gingivitis was associated with longer disease period, high doses of corticosteroids, B-cell hyperactivation and immunoglobulin G elevation. There are scarce data on periodontal diseases in JDM population, and a unique gingival pattern, characterized by gingival erythema, capillary dilation and bush-loop formation, was observed in active patients. In conclusion, gingivitis was the most common periodontal disease in PRD. The observed association with disease activity reinforces the need for future studies to determine if resolution of this complication will influence disease course or severity.

    Introduction: Langerhans cell histiocytosis (LCH) is a rare inflammatory myeloid neoplasia of unknown etiology occurring in both children and adults. This condition is characterized by an abnormal proliferation of Langerhans cells that may virtually affect all sites in the human body. Oral manifestations of LCH could be the first clinical sign of disease and its periodontal localization could be easily mistaken for other more common entities, such as chronic periodontitis, aggressive periodontitis, and necrotizing ulcerative periodontitis. Case presentation: A 32-years old female visited a private dental practice with a chief complaint of sensitivity in the mandibular left first molar. Clinical and radiographic examination revealed deep periodontal pocket, recession, furcation involvement, mobility, severe alveolar bone destruction and a diagnosis of aggressive periodontitis was rendered. Multiple tooth extractions were carried out due to progressive periodontal destruction with impaired healing and development of ulcerative lesions. Multidisciplinary investigation demonstrated that the periodontal involvement was a manifestation of an underlying systemic disease. A biopsy of a bone lesion was therefore performed, revealing the presence of multifocal single system LCH. Conclusion: The identification of periodontal LCH is not trivial given that it may clinically resemble other periodontal disease entities. The dentist can be the first health care personnel to unravel the presence of an underlying systemic LCH. PMID:26722570

    Aim: Reducing the psychosocial stress by various methods can improve overall health, and yoga is now considered as an easily available alternative method. The present cross-sectional pilot study was conducted mainly to find the association of yoga practice with periodontal disease by measuring serum cortisol levels. Materials and Methods: A total of 70 subjects with age range of 35–60 years suffering with chronic periodontitis were divided into group I (with stress), group II (without stress), and group III (practicing yoga). Psychological evaluation was carried out using Hamilton Anxiety Rating Scale (HAM-A) and Zung Self-rating Depression Scale (ZSDS). Periodontal parameters like plaque index (PI), probing pocket depth (PPD), and clinical attachment level (CAL) at 5–8 mm and >8 mm were recorded. Blood samples were collected and serum cortisol levels were measured. Results: Mean age, plaque scores, and number of teeth with PPD and CAL at 5–8 mm and >8 mm were similar in all the groups, except between group I and group III where a multiple comparison with Tukey's post-hoc test showed significant difference in plaque index (P < 0.038) and the number of teeth with CAL 5–8 mm (P < 0.016). Serum cortisol levels and HAM-A scale and ZSDS scores showed highly significant value (P < 0.001) in group I subjects when compared with group II and group III subjects. Conclusion: Cross-sectional observation done among three groups showed that individuals practicing yoga regularly had low serum cortisol levels, HAM-A scale and ZSDS scores, and better periodontal health.

    Glutathione, considered to be the master antioxidant (AO), is the most-important redox regulator that controls inflammatory processes, and thus damage to the periodontium. Periodontitis patients have reduced total AO capacity in whole saliva, and lower concentrations of reduced glutathione (GSH) in serum and gingival crevicular fluid, and periodontal therapy restores the redox balance. Therapeutic considerations for the adjunctive use of glutathione in management of periodontitis, in limiting the tissue damage associated with oxidative stress, and enhancing wound healing cannot be underestimated, but need to be evaluated further through multi-centered randomized controlled trials.

    We investigated whether a family history of lethal prostate cancer (PCa) was associated with high-risk disease or biochemical recurrence in patients undergoing radical prostatectomy. A cohort of radical prostatectomy patients was stratified into men with no family history of PCa (NFH); a first-degree relative with PCa (FH); and those with a first-degree relative who had died of PCa (FHD). Demographic, operative and pathologic outcomes were analyzed. Freedom from biochemical recurrence was examined using Kaplan-Meier log rank. A multivariate Cox logistic regression analysis was also performed. We analyzed 471 men who underwent radical prostatectomy at our institution with known family history. The three groups had: 355 patients (75%) in NFH; 97 patients (21%) in FH; and 19 patients (4%) in FHD. The prevalence of a Gleason score ≥8, higher pathologic T stage, and biochemical recurrence (BCR) rates did not significantly differ between groups. On Kaplan-Meier analysis there were no differences in short-term BCR rates (p = 0.212). In this cohort of patients undergoing radical prostatectomy, those with first-degree relatives who died of PCa did not have an increased likelihood of high-risk or aggressive PCa or shorter-term risk of BCR than those who did not.

    In March 1987, we investigated the quality of oral hygiene, and the incidence of dental caries and periodontal diseases in 140 severely handicapped patients who had been hospitalized in two national sanatorium. All of the patients had participated under the Matsumoto Dental College Hospital Periodic Dental Check-up System for five years. The results were as follows: 1. The teeth of all the subjects had been brushed by the sanatorium nursing staff twice per day. The prevailing brushing technique was the horizontal method. 2. 37.5% of the subjects showed complete adaptability to the tooth brushing by the nursing staff. However, 2.1% showed no adaptability whatsoever. 3. The mean value of the OHI-S was 1.53. The labial surfaces of the maxillary anterior teeth showed the lowest OHI-S value, while the mandibular left posterior teeth showed the highest. 4. The DMF-T was estimated to be 12.51 (DMFT ratio = 48.2%). The average D-T was 2.07 +/- 4.03, and the average F-T was 8.43 +/- 7.22. 5. 19.3% of the patients were diagnosed with gingival hyperplasia, and 10.7% had local gingival recessions. 1) Of the patients who had taken Phenytoin daily, 35.5% were diagnosed with hyperplasia. 2) Most local gingival recessions were found on the labial gingiva of the mandibular anterior teeth. A relationship was determined to exist the local recession and the horizontal brushing method. 6. 89.2% of the patients suffered from periodontal diseases.(ABSTRACT TRUNCATED AT 250 WORDS)

  10. Periodontitis and diabetes interrelationships: role of inflammation.

    PubMed

    Iacopino, A M

    2001-12-01

    Diabetes mellitus is a systemic disease with several major complications affecting both the quality and length of life. One of these complications is periodontal disease (periodontitis). Periodontitis is much more than a localized oral infection. Recent data indicate that periodontitis may cause changes in systemic physiology. The interrelationships between periodontitis and diabetes provide an example of systemic disease predisposing to oral infection, and once that infection is established, the oral infection exacerbates systemic disease. In this case, it may also be possible for the oral infection to predispose to systemic disease. In order to understand the cellular/molecular mechanisms responsible for such a cyclical association, one must identify common physiological changes associated with diabetes and periodontitis that produce a synergy when the conditions coexist. A potential mechanistic link involves the broad axis of inflammation, specifically immune cell phenotype, serum lipid levels, and tissue homeostasis. Diabetes-induced changes in immune cell function produce an inflammatory immune cell phenotype (upregulation of proinflammatory cytokines from monocytes/polymorphonuclear leukocytes and downregulation of growth factors from macrophages). This predisposes to chronic inflammation, progressive tissue breakdown, and diminished tissue repair capacity. Periodontal tissues frequently manifest these changes because they are constantly wounded by substances emanating from bacterial biofilms. Diabetic patients are prone to elevated low density lipoprotein cholesterol and triglycerides (LDL/TRG) even when blood glucose levels are well controlled. This is significant, as recent studies demonstrate that hyperlipidemia may be one of the factors associated with diabetes-induced immune cell alterations. Recent human studies have established a relationship between high serum lipid levels and periodontitis. Some evidence now suggests that periodontitis itself may

    2011-01-01

    From psychological and sociological standpoints, aggression is regarded as intentional behavior aimed at inflicting pain and manifested by hostility and attacking behaviors. In contrast, biologists define aggression as behavior associated with attack or escalation toward attack, omitting any stipulation about intentions and goals. Certain animal signals are strongly associated with escalation toward attack and have the same function as physical attack in intimidating opponents and winning contests, and ethologists therefore consider them an integral part of aggressive behavior. Aggressive signals have been molded by evolution to make them ever more effective in mediating interactions between the contestants. Early theoretical analyses of aggressive signaling suggested that signals could never be honest about fighting ability or aggressive intentions because weak individuals would exaggerate such signals whenever they were effective in influencing the behavior of opponents. More recent game theory models, however, demonstrate that given the right costs and constraints, aggressive signals are both reliable about strength and intentions and effective in influencing contest outcomes. Here, we review the role of signaling in lieu of physical violence, considering threat displays from an ethological perspective as an adaptive outcome of evolutionary selection pressures. Fighting prowess is conveyed by performance signals whose production is constrained by physical ability and thus limited to just some individuals, whereas aggressive intent is encoded in strategic signals that all signalers are able to produce. We illustrate recent advances in the study of aggressive signaling with case studies of charismatic taxa that employ a range of sensory modalities, viz. visual and chemical signaling in cephalopod behavior, and indicators of aggressive intent in the territorial calls of songbirds.

  12. Ultrasonic device for measuring periodontal attachment levels

    Periodontal disease is manifested clinically by a degradation of the ligament that attaches the tooth to the bone. The most widely used diagnostic tool for assessment of periodontal diseases, measurement of periodontal attachment loss with a manual probe, may overestimate attachment loss by as much as 2 mm in untreated sites, while underestimating attachment loss by an even greater margin following treatment. Manual probing is also invasive, which causes patient discomfort. This work describes the development and testing of an ultrasonographic periodontal probe designed to replace manual probing. It uses a thin stream of water to project an ultrasonic beam into the periodontal pocket, and then measures echoes off features within the pocket. To do so, the ultrasonic beam must be narrowed from 2 (the diameter of the transducer) to 0.5 mm (the approximate width of the periodontal pocket at the gingival margin). The proper choice of transducer frequency, the proper method for controlling water flow from the probe, and a model for interpreting these echoes are also addressed. Initial results indicate that the device measures echoes from the hard tissue of the tooth surface, and that the periodontal attachment level can be inferred from these echoes.

    Periodontitis is a chronic, dental-plaque induced inflammatory disease of the tooth-supporting tissues, resulting in a gradual loss of connective tissue attachment and alveolar bone. The interrelationship between diabetes mellitus and periodontitis has been studied for many years. At,present, there is strong evidence to suggest that the incidence and severity of periodontitis is influenced by the presence or absence of diabetes mellitus as well as by the degree of diabetes control by patients. Elevated blood glucose levels in poorly controlled diabetics result in an increase of protein glycosylation leading to amplified formation of so-called Advanced Glycation End products (AGE). AGEs are glucose products that have the ability to attract and stimulate inflammatory cells to produce inflammatory cytokines, elevating the risk of periodontal attachment and/or alveolar bone loss. Gram-negative periodontal infection significantly decreases glucose tolerance and can lead, like other types of inflammation, to an increase in the severity of diabetes. Thus, diabetes and periodontal disease form a system in which periodontitis is aggravated and metabolic control of blood glucose levels becomes more difficult. This in turn leads to mutual aggravation that results in a self-enforcing catabolic process, a vicious circle of inflammation, tissue destruction and insulin resistance. PMID:18044471

    The gentle agitation of suspensions of Actinobacillus actinomycetemcomitans serotype a, b, or c in saline resulted in the release of a proteinaceous surface-associated material (SAM) which produced a dose-dependent inhibition of tritiated thymidine incorporation by the osteoblast-like cell line MG63 in culture. This cell line was sensitive to low concentrations of SAM (50% inhibitory concentration, 200 ng/ml for serotype c). Immunoglobulin G antibodies to constituents of the SAM were found in the blood of patients with localized juvenile periodontitis (LJP). Sera from 9 of 16 patients with LJP significantly neutralized the antiproliferative activity of the SAM, while sera from 15 controls, with no evidence of periodontal disease, were unable to neutralize this activity. Neutralization was not directly related to the patient's antibody titer to the whole SAM. Characterization of the antiproliferative activity in the SAM demonstrated that it was not cytotoxic and was heat and trypsin sensitive. The active component separated in a well-defined peak in anion-exchange high-performance liquid chromatography (HPLC) which, when further analyzed by size exclusion HPLC, revealed a single active peak, which had an apparent molecular mass of approximately 8 kDa. The lipopolysaccharide from A. actinomycetemcomitans was only weakly active. SAM from Porphyromonas gingivalis W50 and Eikenella corrodens NCTC 10596 did not exhibit any antiproliferative activity with this cell line, even at concentrations as high as 10 micrograms/ml. This study has shown that SAM from A. actinomycetemcomitans contains a potent antiproliferative protein whose activity can be neutralized by antibodies in the sera from some patients with LJP.

    Background: The association between interleukin-6 (IL-6) (-174G/C) gene polymorphisms and level of tissue breakdown and periodontal disease progression is unknown. The present study investigated quantitative parameters of interdental papilla in chronic periodontitis (CP) patients with IL-6 (-174G/C) gene polymorphisms. Materials and Methods: Sixty gingival samples were studied. After determination of IL-6 (-174G/C) gene polymorphisms using a tetra-primer amplification refractory mutation system-polymerase chain reaction (T-ARMS-PCR) technique, 45 gingival tissue samples of CP patients (GG and GC+CC genotypes) were considered as case groups. Fifteen control samples were also collected from healthy individuals. After tissue processing, interdental gingival tissues were exhaustively sectioned into 4 μm-thick sections. Ten to thirteen sections were sampled by systematic uniform random sampling and stained with Masson trichrome, and the volume density (Vv) of the gingival components was estimated using Cavalier's point counting method. Statistical analysis was performed by Student t-test to compare differences between groups. The significance level was set at P < 0.05. Results: There were statistically significant differences in the Vv of epithelium, connective tissue, collagenous and non-collagenous matrix, and blood vessels between the control and CP groups (P < 0.0001). There were no statistically significant differences in the Vv of epithelium, connective tissue of gingiva, collagenous and non-collagenous matrix, and blood vessels among GG, GC, and CC genotypes in CP patients (P > 0.05). Conclusion: Results of the current study showed that there was no association between IL-6 (-174G/C) gene polymorphisms and quantitative parameters of interdental papilla in CP patients.

    Exposure to violence from patients or relatives causes problems in emergency departments. To assess the development of posttraumatic symptoms in pre-hospital emergency care professionals assaulted by patients and/or relatives, it may be crucial to establish preventive measures at different levels. This study examined 358 pre-hospital emergency care professionals assaulted by patients and/or relatives. The aims of the present study were (a) to assess the presence of posttraumatic symptoms and posttraumatic stress disorder (PTSD) and (b) identify compliance diagnoses for PTSD depending on the experience of aggression (presence of fear, helplessness, or horror during the aggression), the perceived severity of aggression, and socio-demographic variables (gender, age, profession, employment status, and work experience). The results show that the experience of aggression with fear, helplessness, or horror is associated with the presence of posttraumatic symptoms related to re-experiencing but is not related to avoidance and emotional numbing and arousal. Furthermore, the perception of aggression as severe was associated with the presence of symptoms related to re-experiencing. These results are presented and discussed. PMID:25381283

    Gingival inflammation is highly prevalent among adult populations in all regions of the world. High rates of chronic periodontitis have been reported worldwide. The methods for assessing the gingival inflammation and periodontal disease would need more precision and less user-dependence. The aim of this study consists in identifying the information for diagnosis and staging of periodontal disease using 40 MHz periodontal ultrasonography. Our in vivo study has been made on 49 teeth of 10 patients with marginal periodontal disease. Standard clinical and radiological periodontal examinations were performed. Afterwards the results were compared with the information obtained from images recorded with Ultrasonix SonoTouch used at 40 MHz. On the ultrasound images, were performed very accurate measurements between the cortical bone and the cement-enamel junction or the root wall compared with the measurements made on intraoral digital radiographs. Those measurements could be used to diagnose the bone resorption. In order to monitor the gingival inflammation could be recorded the width of the attached gingival mucosa and the height of the gingival margin on ultrasound images. 40 MHz periodontal ultrasonography is a reliable imagistic method for identifying the necessary anatomical elements in order to make an accurate periodontal diagnosis for the examined area.

    Background The aim of this review is to systematically investigate the effect of a susceptible genotype to periodontitis with the clinical outcomes of periodontal regeneration. Material and Methods Based on a focused question, an electronic search identified 155 unique citations. Three journals (Journal of Periodontology, Journal of Clinical Periodontology and Journal of Periodontal Research), references of relevant studies and review articles were hand-searched. Two independent reviewers implementing eligibility inclusion criteria selected the studies. Results Of the 155, four studies fulfilled the inclusion criteria. All studies were published between 2000 and 2004 and the samples’ size was 40 to 86 patients. Polymorphisms of Interleukin-1 (IL-1) gene were included in all. Three out of four studies failed to identify an association between susceptible genotypes to periodontitis and clinical outcomes of periodontal regeneration, while one found an association. The heterogeneity and small number of studies included prevented the conduct of a meta-analysis. No studies were identified evaluating the effect of other genotypes and as a result only IL-1 genotype studies were included. Conclusions Within the limits of the present review, no direct conclusion for the effect of a susceptible IL-1 genotype status to the clinical outcome after periodontal regeneration could be drawn. The need of more qualitative studies to explore a possible association emerges. Key words:Periodontitis, genotype, periodontal therapy, regeneration, susceptibility, systematic review. PMID:26946210

  19. Point-of-care diagnosis of periodontitis using saliva: technically feasible but still a challenge.

    Periodontitis is a chronic inflammation of the periodontium caused by persistent bacterial infection that leads to the breakdown of connective tissue and bone. Because the ability to reconstruct the periodontium is limited after alveolar bone loss, early diagnosis and intervention should be the primary goals of periodontal treatment. However, periodontitis often progresses without noticeable symptoms, and many patients do not seek professional dental care until the periodontal destruction progresses to the point of no return. Furthermore, the current diagnosis of periodontitis depends on time-consuming clinical measurements. Therefore, there is an unmet need for near-patient testing to diagnose periodontitis. Saliva is an optimal biological fluid to serve as a near-patient diagnostic tool for periodontitis. Recent developments in point-of-care (POC) testing indicate that a diagnostic test for periodontitis using saliva is now technically feasible. A number of promising salivary biomarkers associated with periodontitis have been reported. A panel of optimal biomarkers must be carefully selected based on the pathogenesis of periodontitis. The biggest hurdle for the POC diagnosis of periodontitis using saliva may be the process of validation in a large, diverse patient population. Therefore, we propose the organization of an International Consortium for Biomarkers of Periodontitis, which will gather efforts to identify, select, and validate salivary biomarkers for the diagnosis of periodontitis.

    X-linked acro-gigantism (X-LAG) syndrome is a newly described disease caused by microduplications on chromosome Xq26.3 leading to copy number gain of GPR101. We describe the clinical progress of a sporadic male X-LAG syndrome patient with an Xq26.3 microduplication, highlighting the aggressive natural history of pituitary tumor growth in the absence of treatment. The patient first presented elsewhere aged 5 years 8 months with a history of excessive growth for >2 years. His height was 163 cm, his weight was 36 kg, and he had markedly elevated GH and IGF-1. MRI showed a non-invasive sellar mass measuring 32.5 × 23.9 × 29.1 mm. Treatment was declined and the family was lost to follow-up. At the age of 10 years and 7 months, he presented again with headaches, seizures, and visual disturbance. His height had increased to 197 cm. MRI showed an invasive mass measuring 56.2 × 58.1 × 45.0 mm, with compression of optic chiasma, bilateral cavernous sinus invasion, and hydrocephalus. His thyrotrope, corticotrope, and gonadotrope axes were deficient. Surgery, somatostatin analogs, and cabergoline did not control vertical growth and pegvisomant was added, although vertical growth continues (currently 207 cm at 11 years 7 months of age). X-LAG syndrome is a new genomic disorder in which early-onset pituitary tumorigenesis can lead to marked overgrowth and gigantism. This case illustrates the aggressive nature of tumor evolution and the challenging clinical management in X-LAG syndrome. PMID:26607152

    The aim of this study was to assess the changes occurring in subgingival biofilm composition and in the periodontal clinical parameters of subjects with periodontitis and type 2 diabetes mellitus (DM) treated by means of scaling and root planing (SRP) only or combined with systemic metronidazole (MTZ) and amoxicillin (AMX). Fifty-eight subjects were randomly assigned to receive SRP only (n = 29) or with MTZ (400 mg/thrice a day [TID]) and AMX (500 mg/TID) (n = 29) for 14 d. Six subgingival plaque samples/subject were analyzed by checkerboard DNA-DNA hybridization for 40 bacterial species at baseline and 3 mo, 1 y, and 2 y posttherapy. At 2 y posttherapy, the antibiotic-treated group harbored lower mean proportions (5.5%) of red complex pathogens than the control group (12.1%) (P < 0.05). The proportions of the Actinomyces species remained stable in the antibiotic group but showed a statistically significant reduction in the control group from 1 to 2 y in subjects achieving a low risk clinical profile for future disease progression (i.e., ≤4 sites with probing depth [PD] ≥5 mm). The test group also had a lower mean number of sites with PD ≥5 mm (3.5 ± 3.4) and a higher percentage of subjects reaching the low risk clinical profile (76%) than the control group (14.7 ± 13.1 and 22%, respectively) (P < 0.05) at 2 y posttreatment. MTZ + AMX intake was the only significant predictor of subjects achieving the low risk at 2 y (odds ratio, 20.9; P = 0.0000). In conclusion, the results of this study showed that the adjunctive use of MTZ + AMX improves the microbiological and clinical outcomes of SRP in the treatment of subjects with generalized chronic periodontitis and type 2 DM up to 2 y (ClinicalTrials.gov NCT02135952).

    Purpose The aim of this research was to investigate the association of chronic and aggressive periodontitis with the severity of coronary artery disease which was angiographically verified. Material and methods Subjects were selected among the hospitalized patients at the University Hospital Centre Zagreb who had coronary angiography done because of the chest pain. Thorough clinical examination included periodontal indices and clinical and socio-demographic characteristics of participants. Subjects were divided in two test groups, acute coronary syndrome (ACS) and stable coronary artery disease (CAD), and the control group with no significant CAD. Data were analyzed using Kruskal-Wallis and Pearson’s Chi-Square test. Results From 106 subjects, 66 (62.3%) were hospitalized for ACS, 22 (20.7%) had stable CAD and only 18 (17.0%) had no significant CAD. Only 26 (24.5%) out of 106 patients were never smokers (p<0.05). Chronic periodontitis was the most common finding with 68.2% in ACS group and 54.5% in stable CAD group, while healthy patients without periodontitis (72.6%) were dominant in the control group (p<0.001). Stable CAD group had the highest mean probing depth (PD) 3.92±1.16, gingival recession (GR) 1.34±0.78, clinical attachment level (CAL) 4.60±1.41 and bleeding on probing (BOP) 45.98±26.19 values, whereas ACS group had mean PD value of 3.77±0.91, GR 1.11±0.66, CAL 4.32±1.08 and BOP 41.30±22.09, and no significant CAD group had mean PD value of 3.27±0.97, GR 0.69±0.37, CAL 3.62±1.04 and BOP 26.39±13.92 (p<0.05). Conclusion Periodontitis was shown to be associated with angiographically verified coronary artery disease. Physical inactivity, poor oral hygiene and periodontal inflammation were observed in patients with ACS and stable CAD.

    Epidemiological data indicate an association between periodontitis and obesity. The biological mechanisms of this relationship remain unclear. A cross-sectional study was conducted to evaluate the relationship between periodontitis and the common systemic inflammatory markers in 32 morbidly obese patients recruited in a Clinical Nutrition department. Periodontal condition was evaluated using pocket depth (PD) measurement, a classical clinical marker of ongoing periodontitis. Major periodontal risk factors were recorded (age, gender, diabetes and smoking status), as well as plasma levels of inflammatory markers (CRP, orosomucoid, IL-6) and adipokines (adiponectin, leptin). All patients included in the sample exhibited evidence of periodontitis, 16 of whom were diagnosed as having severe disease. Adjusted logistic regression analysis indicated that the severity of periodontitis was associated with the plasma level of orosomucoid (p<0.04) after adjustment for age, gender and smoking. Our study thus suggests that the severity of periodontitis, in morbidly obese patients, is associated with the increase of orosomucoid levels. PMID:23526947

    Periodontitis is a disease that leads to bone destruction and represents the main cause of tooth loss in adults. The development of aggressive periodontitis has been associated with increased inflammatory response that is induced by the presence of a subgingival biofilm containing Aggregatibacter actinomycetemcomitans. The flavonoid quercetin (1) is widespread in vegetables and fruits and exhibits many biological properties for possible medical and clinical applications such as its anti-inflamatory and antioxidant effects. Thus, in the present study, the properties of 1 have been evaluated in bone loss and inflammation using a mouse periodontitis model induced by A. actinomycetemcomitans infection. Subcutaneous treatment with 1 reduced A. actinomycetemcomitans-induced bone loss and IL-1β, TNF-α, IL-17, RANKL, and ICAM-1 production in the gingival tissue without affecting bacterial counts. These results demonstrated that quercetin exhibits protective effects in A. actinomycetemcomitans-induced periodontitis in mice by modulating cytokine and ICAM-1 production.

    In 30 patients with periodontitis, a total of 278 teeth exhibiting bleeding on probing, subgingival calculus, and a probing depth between 3-6 mm were examined. For each participant, two treatment types were alternatively applied on the contralateral quadrants: scaling and root planing (SRP) as control, and SRP followed by Er,Cr:YSGG laser application (SRP+laser), as a test method. Five clinical parameters: plaque level, bleeding on probing, probing depth, gingival recession and clinical attachment level were examined at baseline and at 2, 3, 6, 12 months after treatment. Of the total of 1,668 sites examined in all patients, 1,088 sites were found with a probing depth of 3-6 mm. In these sites, differences in clinical parameters between SRP and SRP+laser-treated quadrants were analyzed, assuming the level of p < 0.05 as significant. After 2 months from baseline, the mean probing depth reduction and the clinical attachment level gain were significantly greater in SRP+laser than in SRP quadrants, and remained so throughout the study (p < 0.001). A marked reduction of the bleeding scores occurred in all examined sites, irrespective of the treatment method. However, after 12 months, significantly less teeth exhibited bleeding on probing in SRP+laser quadrants than in SRP quadrants (p < 0.001). The mean plaque and gingival recession levels did not differ between the SRP and SRP+laser quadrants neither before nor after the treatment. The periodontal procedures either using Er,Cr:YSGG laser after SRP or SRP alone, lead to significant improvements in all clinical parameters investigated. However, laser application, as an adjunct to SRP, appeared to be more advantageous.

    Gingival and Periodontal diseases represent a major concern both in dentistry and medicine. The majority of the contributing factors and causes in the etiology of these diseases are reduced or treated with ozone in all its application forms (gas, water, oil). The beneficial biological effects of ozone, its anti-microbial activity, oxidation of bio-molecules precursors and microbial toxins implicated in periodontal diseases and its healing and tissue regeneration properties, make the use of ozone well indicated in all stages of gingival and periodontal diseases. The primary objective of this article is to provide a general review about the clinical applications of ozone in periodontics. The secondary objective is to summarize the available in vitro and in vivo studies in Periodontics in which ozone has been used. This objective would be of importance to future researchers in terms of what has been tried and what the potentials are for the clinical application of ozone in Periodontics. PMID:22574088

    Medically compromised patients attending the dental clinic at the Toronto Rehabilitation Institute have considerable gingival inflammation and breath odor. The objective of this study was to evaluate the effect of toothbrushing on the periodontal status of these patients and to determine if there were any additional benefit in combining brushing with an application of an antibiotic rinse. During the first 7 days of the study, the teeth of 11 participants were brushed twice a day by a dental hygienist using a soft-bristle suction toothbrush without toothpaste. Soft interproximal brushes were used to clean interproximal surfaces from the facial aspect. During the second week, facial and interproximal cleaning were repeated in the same patients, but the toothbrush and interproximal brush were dipped in 10-mL of a solution consisting of water and 40 mg/mL of metronidazole with nystatin. Each patient underwent an oral examination and biofilm sampling at baseline, after brushing without toothpaste (week 1), and after brushing with antibiotic solution (week 2). After week 1, tissues improved substantially, and there was a notable change in the biofilm on the teeth. The addition of an antibiotic solution increased healing and resulted in a further decrease in oral biofilm. Medically compromised patients would benefit considerably from a treatment regimen of antibiotic solution to decrease oral infection followed by a daily oral care program of brushing and interdental cleaning to maintain healthy oral tissues.

    Background: Periodontitis is common in adults and cardiovascular diseases (CVD) are the most common cause of adult death in the world. This study aimed to investigate the relationship between CVD and periodontitis. Methods: Sixty patients with myocardial infarction (MI) as case and 63 subjects with periodontitis without MI as control were studied. Periodontitis was assessed according to Ramfjord periodontal diseases index and the number of missing teeth besides classic risk factors of MI were recorded. Results: The patients who lost more than 10 teeth were at more risk of myocardial infarction (OR=2.73). There was a significant relationship between mean attachment loss and MI (p=0.0001). There was also a relation between attachment loss more than 3 mm and MI with OR of 4. Significant difference between mean PDI (periodontal disease index) was seen in case and control groups (p=0.0001). Subjects with PDI>4 were at more risk of periodontal diseases (OR=7.87). Conclusion: The results show the presence of significant relation between periodontitis and MI which could serve as an alarm to treat periodontitis carefully. PMID:24009957

    Objectives. The aim of this study is to estimate the economic burden associated with the management of periodontitis in Malaysia from the societal perspective. Methods. We estimated the economic burden of periodontitis by combining the disease prevalence with its treatment costs. We estimated treatment costs (with 2012 value of Malaysian Ringgit) using the cost-of-illness approach and included both direct and indirect costs. We used the National Oral Health Survey for Adults (2010) data to estimate the prevalence of periodontitis and 2010 national census data to estimate the adult population at risk for periodontitis. Results. The economic burden of managing all cases of periodontitis at the national level from the societal perspective was approximately MYR 32.5 billion, accounting for 3.83% of the 2012 Gross Domestic Product of the country. It would cost the nation MYR 18.3 billion to treat patients with moderate periodontitis and MYR 13.7 billion to treat patients with severe periodontitis. Conclusion. The economic burden of periodontitis in Malaysia is substantial and comparable with that of other chronic diseases in the country. This is attributable to its high prevalence and high cost of treatment. Judicious application of promotive, preventive, and curative approaches to periodontitis management is decidedly warranted.

    Background: Clinical attachment level is the most frequently used and acceptable parameter in monitoring periodontal status in diseased individual and denotes patterns of periodontal destruction. Awareness of root morphology and the condition of the periodontal tissues is essential for reliable periodontal pocket probing and for effective debridement of root surfaces. Clinically, it is challenging to observe exact nature of complex periodontal attachment loss. The aim of the present study was to evaluate patterns of periodontal destruction based on vertical and horizontal attachment loss. Materials and Methods: A total of 200 extracted teeth were obtained from chronic periodontitis patients. Prior to extraction, clinical measurements were recorded and after extraction, the teeth were stained with crystal violet. Root length, vertical and horizontal attachment loss were measured using digital caliper. Results: There was a significant difference between clinical attachment level and vertical attachment loss for both maxillary and mandibular teeth. Mean vertical attachment loss varied between 5.17 mm and 9.17 mm. Interproximal surfaces exhibited statistically significant vertical attachment loss in both maxillary and mandibular dentition. Results indicated that vertical attachment loss was more severe with teeth belonging to the anterior sextant whereas the horizontal attachment loss was more pronounced with posterior teeth. Conclusion: Both vertical and horizontal attachment loss were observed in all periodontally involved teeth. There was a difference in clinical measurements and actual periodontal status denoted by postextraction staining. These findings have an impact on determining the prognosis and appropriate treatment plan for patients. PMID:27143828

    Cemento-ossifying fibroma (COF) is a rare nonodontogenic tumor of the periodontal membrane that arises from the mesodermal germ layer. Clinically, these lesions are usually asymptomatic, slowly growing, and well circumscribed. However, they have demonstrated an aggressive course of development in a very small number of cases, particularly in younger patients. Surgical management via wide local excision is necessary because COF is notorious for recurrence, particularly lesions in the paranasal sinuses. We describe a case of juvenile aggressive COF of the sinonasal tract in a 12-year-old boy. This tumor presented with various overlapping clinical, radiologic, and pathologic features, which led to initial confusion and a diagnostic dilemma. We also discuss the radiologic interpretation of COF, which can be helpful in making the diagnosis and in selecting the appropriate surgical approach in a growing child.

    The adoption of new technologies for the treatment of periodontitis and the replacement of teeth has changed the delivery of periodontal care. The objective of this review was to conduct an economic analysis of a mature periodontal service market with a well-developed workforce, including general dentists, dental hygienists and periodontists. Publicly available information about the delivery of periodontal care in the USA was used. A strong trend toward increased utilization of nonsurgical therapy and decreased utilization of surgical periodontal therapy was observed. Although periodontal surgery remained the domain of periodontists, general dentists had taken over most of the nonsurgical periodontal care. The decline in surgical periodontal therapy was associated with an increased utilization of implant-supported prosthesis. Approximately equal numbers of implants were surgically placed by periodontists, oral and maxillofacial surgeons, and general dentists. Porter's framework of the forces driving industry competition was used to analyze the role of patients, dental insurances, general dentists, competitors, entrants, substitutes and suppliers in the periodontal service market. Estimates of out-of-pocket payments of self-pay and insured patients, reimbursement by dental insurances and providers' earnings for various periodontal procedures and alternative treatments were calculated. Economic incentives for providers may explain some of the observed shifts in the periodontal service market. Given the inherent uncertainty about treatment outcomes in dentistry, which makes clinical judgment critical, providers may yield to economic incentives without jeopardizing their ethical standards and professional norms. Although the economic analysis pertains to the USA, some considerations may also apply to other periodontal service markets.
