Objective: Periodontitis is considered to be a risk factor for systemic diseases such as atherosclerosis, diabetes, etc., and cytokines play a key role. The present study was carried out to measure the level of serum oncostatin M (OSM) in patients with chronic periodontitis, and to evaluate the effect of non-surgical periodontal therapy on the serum OSM concentration.

Materials and methods: Sixty subjects were divided into three groups (each group n?=?20) based on the gingival index (GI), probing pocket depth (PPD) and clinical attachment level (CAL): group I healthy; group II gingivitis; and group III chronic periodontitis. Group III patients were followed for 8 weeks after non-surgical periodontal therapy as the after-treatment group (group IV). Estimation of serum OSM was done using an enzyme-linked immunosorbent assay.

Results: The mean OSM concentrations in serum were highest in the chronic periodontitis group (mean 68.05 pg ml?1) and decreased following treatment (39.65 pg ml?1) while OSM was undetectable in healthy subjects or in patients with gingivitis.

Conclusion: Increased serum OSM concentration in patients with chronic periodontitis and its positive correlation with PPD and CAL, suggest its role as an inflammatory biomarker in periodontal disease and it may exaggerate other systemic conditions such as atherosclerosis and rheumatoid arthritis.  相似文献

Background

The contribution of HIV-infection to periodontal disease (PD) is poorly understood.  We proposed that immunological markers would be associated with improved clinical measures of PD.

Methods

We performed a longitudinal cohort study of HIV-infected adults who had started highly active antiretroviral therapy (HAART) <2 years. PD was characterized clinically as the percent of teeth with ≥1 site with periodontal probing depth (PPD) ≥5.0mm, recession (REC) >0mm, clinical attachment level (CAL) ≥4.0mm, and bleeding on probing (BOP) at ≥4 sites/tooth and microbiologically as specific periodontopathogen concentration. Linear mixed-effects models were used to assess the associations between immune function and PD.

Results

Forty (40) subjects with median 2.7 months on HAART and median nadir CD4+ T-cell count of 212 cells/μl completed a median 3 visits. Over 24 months, CD4+ T-cell count increased by a mean 173 cells/µl (p<0.001) and HIV RNA decreased by 0.5 log10 copies/ml (p<0.001); concurrently, PPD, CAL and BOP decreased by a mean 11.7%, 12.1%, and 14.7% respectively (all p<0.001). Lower nadir CD4+ T-cell count was associated with worse baseline REC (-6.72%; p=0.04) and CAL (9.06%; p<0.001). Further, lower nadir CD4+ T-cell count was associated with a greater relative longitudinal improvement in PPD in subjects with higher baseline levels of Porphyromonas gingivalis (p=0.027), and BOP in subjects with higher baseline levels of Porphyromonas gingivalis or Treponema denticola (p=0.001 and p=0.006 respectively). Longitudinal changes from baseline in CD4+ T-cell count and level of HIV RNA were not independently associated with longitudinal changes in any clinical markers of PD.

Conclusion

Degree of immunosuppression was associated with baseline gingival recession. After HAART initiation, measures of active PD improved most in those with lower nadir CD4+ T-cell counts and higher baseline levels of specific periodontopathogens. Nadir CD4+ T-cell count differentially influences periodontal disease both before and after HAART in HIV-infected adults.  相似文献

Periodontal regenerative therapy is aimed at reconstruction and to restore the architecture and function of lost or injured tissues. Melcher (J Periodontol 47(5):256–260, 1976) introduced the concept of guided tissue regeneration (GTR) for osseous reconstructive surgery. The aim of the present innovative clinical and radiographic study was to evaluate the effect of chorionic membrane (CM) in GTR in periodontal pocket therapy. Ten patients with moderate to severe periodontitis were selected in the single blind randomized controlled clinical trial. Patients were treated with periodontal pocket therapy along with CM in study sites and the control sites were treated with periodontal pocket therapy alone. The clinical parameters were recorded at baseline and 12 months. The radiographic parameters were recorded at baseline, 6 and 12 months. Clinical parameters included gingival index (GI), plaque index (PI), pocket probing depth (PPD) and relative attachment level (RAL). Digital images were analysed for bone gain (BG) and density. Data were evaluated using t test. Statistical significant differences were found in both sites at 12 months for GI, PI, PPD and RAL. Highly significant reduction was seen in GI 0.40 ± 0.08 (p = 0.0001), PI (0.41 ± 0.18), PPD 2.50 ± 0.53 mm (p = 0.0431) and increased BG 0.86 ± 0.18 (p < 0.0001) were observed in study sites. This shows that CM when used with pocket therapy can have influence on clinical parameters. Radiographic findings from this study demonstrated significant BG and density in sites treated with CM as compared to control sites.  相似文献

The longitudinal relationship between dietary n-6 to n-3 PUFAs ratio and periodontal disease in 235 Japanese subjects for whom data were available for the years 2003-2006 was investigated. PUFAs intake was assessed at baseline with a brief-type self-administered diet history questionnaire. Full-mouth periodontal status, measured as the clinical attachment level (CAL), was recorded at baseline and once a year for 3 years. The number of teeth with a change in the loss of CAL ≥3 mm at any site over a year was calculated as ‘periodontal disease events’. Poisson regression analysis was conducted, with dietary n-6 to n-3 PUFAs ratio as the main predictor, to estimate its influence on periodontal disease events.A high dietary n-6 to n-3 PUFAs ratio was significantly associated with greater number of periodontal disease events. The findings suggest the dietary n-6 to n-3 PUFAs ratio is associated with periodontal disease among older Japanese.  相似文献

doi: 10.1111/j.1741‐2358.2011.00507.x Oral status in home‐dwelling elderly dependent on moderate or substantial supportive care for daily living: prevalence of edentulous subjects, caries and periodontal disease Objectives: The aim of this study was to compare the prevalence of edentulous subjects, caries and periodontal disease among the home‐dwelling elderly with moderate and substantial needs of support for daily living. Materials and method: A sample of 302 randomly selected elderly with moderate or substantial needs of supportive care were examined in Sweden. Several oral clinical variables were registered: number of teeth, dentures, caries, probing pocket depth, gingival bleeding and Eichner’s index. Results: Both in general and in oral health, the differences were small when comparing elderly with moderate and substantial care needs for daily living. Those with substantial needs had more caries lesions (p < 0.01) and more gingival bleeding (p < 0.05), while the number of teeth and prevalence of edentulous subjects did not differ in relation to the need of daily support. The elderly had, on average, 9.8–11.7 teeth, one‐third of whom had no natural teeth. According to Eichner’s index, half of the elderly in both groups had no opposing tooth contacts. Fifty‐five per cent used dentures. Conclusions: Elderly people with needs of supportive care have lost many teeth before they become dependent. Health promotion should be a priority in early ageing populations to prevent oral diseases and tooth loss.  相似文献

The association between renal function and tooth loss in Japanese community‐dwelling postmenopausal women Objectives: This study examined whether low renal function is associated with the number of remaining teeth among community‐dwelling elderly Japanese. Background data: Many elderly individuals display both low renal function and tooth loss. Materials and Methods: Subjects comprised 405 randomly selected women (55–74 years old). Serum cystatin C level was used to assess renal dysfunction. Multiple linear regression analysis was used to evaluate the relationship between number of remaining teeth and serum cystatin C level, with number of remaining teeth as the dependent variable. Six variables were selected as independent variables in the final model: serum cystatin C; age; mean clinical attachment level; serum cross‐linked N‐telopeptide of type I collagen level; body mass index and smoking habits. Results: Multiple linear regression analysis revealed a significant relationship between number of remaining teeth and serum cystatin C level. The beta value for serum cystatin C level for the number of remaining teeth was ?0.11 (p = 0.018). Conclusion: This study indicates a relationship between serum cystatin C level and number of remaining teeth, suggesting that low renal function could be associated with tooth loss.  相似文献

Objective: We hypothesise that a difference in nutrition influences dental caries and periodontal disease. There are few previous studies especially longitudinal ones which have evaluated this hypothesis. This study investigated the relationship between nutritional intake, including milk and milk products (MMP), and dental disease, controlling for several confounding factors. Material and methods: A group of 600 subjects aged 70, randomly selected for this study, included approximately the same number of male and female subjects. The number of teeth on which root caries had occurred or where there was a periodontal event over a 6‐year period was measured. To determine quantitative food intake at baseline, a semi‐quantitative food frequency questionnaire was used during face‐to‐face interviews by dieticians. The stepwise method of multiple linear regression analysis was used to identify independent predictors of the number of root caries or periodontal disease events during the 6 years. Intake of the six food groups includes (i) fish, shellfish, meat, beans and eggs; (ii) MMP; (iii) dark green and yellow vegetables (DYV); (iv) other vegetables and fruits; (v) cereals, nuts and seeds, sugar and sweeteners, confectioneries (CNSC) and (vi) fats and oils. The alcohol, gender and anthropometric evaluation including measurements of weight and height for the calculation of body mass index, educational level, the number of family members and the number of remaining teeth were used as independent variables. Results: According to stepwise multiple regression analysis, two variables (quantity of MMP, and gender) were negatively associated with the number of root caries events during the 6 years. The standardised coefficients were ?0.14 (p = 0.035) and ?0.17 (p = 0.007) respectively. In addition, DYV were negatively, and three other variables (CNSC; alcohol; and the number of remaining teeth at baseline) were positively associated with the number of periodontal disease events during the 6 years. The standardised coefficients were ?0.16 (p = 0.001), 0.11 (p = 0.042), 0.10 (p = 0.041) and 0.58 (p < 0.001) respectively. Conclusion: Our results suggest that the intake of MMP in this elderly population correlated with root caries events. In addition, intake of vegetables negatively correlated, and intake of ‘CNSC’ positively correlated with periodontal disease events.  相似文献

Background

In COPD patients, fatal and non-fatal respiratory-related events are influenced by age, severity of respiratory disease, and comorbidities.

Objectives

Analyze the effects of edentulism, periodontal disease and systemic biomarkers of inflammation on the occurrence of serious fatal and non-fatal respiratory-related events among subjects with COPD.

Methods

Cases were identified from Dental Atherosclerosis Risk in Communities study. Edentulism was defined as study participants without any natural teeth or implants. Participants with one or more natural teeth (comprising 11,378 subjects) were studied as dentate subjects. Periodontal disease status among dentate individuals was determined using the consensus definitions published by the joint Center for Disease Control/American Association of Periodontology working group). Adjusted Hazard Models are developed to evaluate the relationship between edentulism/periodontal disease and COPD Related Events. Models were then stratified by GOLD Stage I, II and III/IV. Serum biomarkers were also evaluated to explore the effect of systemic inflammation.

Results

A statistically significant association was found between oral health status and COPD-related events, even adjusting for conditions such as hypertension, smoking and diabetes. Edentulous individuals who had been diagnosed with COPD had a higher incidence and were at greater risk of having a COPD related event (hospitalization and death) than individuals who had teeth and whose mouths had healthy periodontal status. However, being edentulous did not convey excess risk for COPD-related events for those study participants who were classified as GOLD III/IV at baseline. Finally, we showed that individuals who had levels of serum IL-6 in the highest two quartiles were at even higher risk for COPD-related events.

Conclusions

These findings suggest that the risk for COPD-related events after adjusting for potential confounders may be attributable to both edentulism and elevated serum IL-6 levels.  相似文献

ObjectiveThough gingivitis is common in children with type 1 diabetes mellitus (T1DM), the overall periodontal health in T1DM during the pubertal stage is less well-characterized. The study was undertaken to explore the possible influence of puberty and metabolic derangement on periodontal health in T1DM.MethodsIn this cross-sectional study, 110 subjects between 10-18 years with T1DM and 52 healthy siblings of similar age were evaluated for pubertal stage, glycosylated hemoglobin (HbA1c), and periodontal health. Simplified oral hygiene index (OHIS), gingival index (GI), plaque index (PI), bleeding on probing (BOP), and probing depth (PPD) were evaluated at 4 sites per tooth as per 6 Ramfjord index teeth used to assess periodontal disease (PD).ResultsPD not merely gingivitis was significantly higher in T1DM (84/110, 76.36%) than the control group (28/52, 53.8%) (P = .004). Irrespective of pubertal status, children with T1DM had worse GI, PI, BOP, and PPD than nondiabetic subjects, although OHIS was better in diabetes. In both T1DM and nondiabetic subjects, pubertal subjects showed significantly worse OHIS, PPD, BOP, and GI than prepubertal subjects. PD was correlated with pubertal stage, age, and HbA1c, although less strongly with the duration of diabetes. In logistic regression, pubertal stage was a stronger predictor of PD (OR = 14.26) than age (OR = 2.22), and HbA1c (OR = 1.5) rather than the presence of diabetes and its duration.ConclusionsThough pubertal status, age, and poor glycemic control rather than the presence of diabetes and its duration are associated with gingivitis and other forms of PD, puberty had a more profound effect in the pathogenesis of PD in T1DM.  相似文献

Heading of cereals is determined by complex genetic and environmental factors in which genes responsible for vernalization and photoperiod sensitivity play a decisive role. Our aim was to use diagnostic molecular markers to determine the main allele types in VRN-A1, VRN-B1, VRN-D1, PPD-B1 and PPD-D1 in a worldwide wheat collection of 683 genotypes and to investigate the effect of these alleles on heading in the field. The dominant VRN-A1, VRN-B1 and VRN-D1 alleles were present at a low frequency. The PPD-D1a photoperiod-insensitive allele was carried by 57 % of the cultivars and was most frequent in Asian and European cultivars. The PPD-B1 photoperiod-insensitive allele was carried by 22 % of the genotypes from Asia, America and Europe. Nine versions of the PPD-B1-insensitive allele were identified based on gene copy number and intercopy structure. The allele compositions in PPD-D1, PPD-B1 and VRN-D1 significantly influenced heading and together explained 37.5 % of the phenotypic variance. The role of gene model increased to 39.1 % when PPD-B1 intercopy structure was taken into account instead of overall PPD-B1 type (sensitive vs. insensitive). As a single component, PPD-D1 had the most important role (28.0 % of the phenotypic variance), followed by PPD-B1 (12.3 % for PPD-B1_overall, and 15.1 % for PPD-B1_intercopy) and VRN-D1 (2.2 %). Significant gene interactions were identified between the marker alleles within PPD-B1 and between VRN-D1 and the two PPD1 genes. The earliest heading genotypes were those with the photoperiod-insensitive allele in PPD-D1 and PPD-B1, and with the spring allele for VRN-D1 and the winter alleles for VRN-A1 and VRN-B1. This combination could only be detected in genotypes from Southern Europe and Asia. Late-heading genotypes had the sensitivity alleles for both PPD1 genes, regardless of the allelic composition of the VRN1 genes. There was a 10-day difference in heading between the earliest and latest groups under field conditions.  相似文献

Gerodontology 2012; doi: 10.1111/j.1741‐2358.2012.00672.x The relationship between seven health practices and oral health status in community‐dwelling elderly Thai Objective: This study aims to analyse the relationship between seven health practices, oral health behaviors, and oral health status in community dwelling elderly Thai. Materials and methods: The subjects were 612 elderly people (mean age = 68.8 ± 5.9 years). Questionnaires survey about sociodemographics, self‐reported seven health practices and oral health behaviors were conducted by trained interviewers. Oral examinations investigated the number of teeth present, decayed teeth, periodontal status and functional tooth units (FTUs). Oral malodor was assessed by Organoleptic Test, and unstimulated saliva was collected for 5 min. Results: Five health practices (smoking, drinking, physical activity, breakfast and weight maintenance) were significantly related with oral health behaviors. ancova analysis demonstrated the following significant associations: (i) smoking behavior with number of teeth present, number of FTUs, decayed teeth, periodontal disease, oral malodor and salivary flow rate, (ii) drinking alcohol behavior with number of teeth present, number of FTUs, periodontal disease, oral malodor and salivary flow rate, (iii) eating breakfast behavior with periodontal disease, oral malodor and salivary flow rate, (iv) eating between‐meal snack with number of teeth present, number of FTUs, decayed teeth and periodontal disease, (v) maintaining weight with number of teeth present, number of FTUs, periodontal disease and oral malodor, (vi) sleeping with number of teeth present, number of FTUs, periodontal disease, oral malodor and salivary flow rate, (vii) physical activity with periodontal disease and salivary flow rate. Conclusion: Good health practices were related with good oral health behaviors. Moreover, general health practices were associated with the clinical oral health status such as number of teeth present, decayed teeth, FTUs, periodontal disease, oral malodor and salivary flow rate. The elderly with good general health practices were considered to have good oral health status. Improving general health habits are suggested to lead to better oral health for the elderly, and vice versa.  相似文献

A large body of evidence underlines an association between periodontal disease and cardiovascular disease. In contrast, data on its relation with endothelial dysfunction as a marker of early subclinical atherosclerosis is inconclusive and limited to patient-cohort studies. We therefore investigated the association between periodontal disease and flow-mediated dilation of the brachial artery (FMD) as a measure of endothelial dysfunction in a general population, and also addressed a possible mediation via inflammation. The study population comprised 1,234 subjects (50.5% men) aged 25–85 years from the 5-year follow-up of the Study of Health in Pomerania, a population-based cohort study. Clinical attachment loss (CAL) and pocket probing depth (PPD) as measures of periodontal disease were assessed half-mouth at four sites per tooth. Subjects were classified according to the periodontitis case definition proposed by Tonetti and Claffey (2005). Measurements of FMD and nitroglycerin-mediated dilation (NMD) were performed using standardized ultrasound techniques. High-sensitive C-reactive protein, fibrinogen and leukocyte count were measured. Fully adjusted multivariate linear regression analyses revealed significant associations of the percentage of sites with PPD ≥6 mm with FMD (ptrend=0.048), with subjects within the highest category having a 0.74% higher FMD compared to subjects within the lowest category (p<0.05). Consistently, FMD values increased significantly across categories of the percentage of sites with CAL ≥6 mm (ptrend=0.01) and the periodontitis case definition (ptrend=0.006). Restrictions to subjects without antihypertensive or statin medication or current non-smokers confirmed previous results. Systemic inflammation did not seem to mediate the relation. Both PPD and CAL were not consistently associated with NMD. In contrast to previous studies, high levels of periodontal disease were significantly associated with high FMD values. This association was not mediated via systemic inflammation. This study revives the discussion on whether and how periodontitis contributes to endothelial dysfunction.  相似文献

In surveillance studies of periodontal disease, the relationship between disease and other health and socioeconomic conditions is of key interest. To determine whether a patient has periodontal disease, multiple clinical measurements (eg, clinical attachment loss, alveolar bone loss, and tooth mobility) are taken at the tooth‐level. Researchers often create a composite outcome from these measurements or analyze each outcome separately. Moreover, patients have varying number of teeth, with those who are more prone to the disease having fewer teeth compared to those with good oral health. Such dependence between the outcome of interest and cluster size (number of teeth) is called informative cluster size and results obtained from fitting conventional marginal models can be biased. We propose a novel method to jointly analyze multiple correlated binary outcomes for clustered data with informative cluster size using the class of generalized estimating equations (GEE) with cluster‐specific weights. We compare our proposed multivariate outcome cluster‐weighted GEE results to those from the convectional GEE using the baseline data from Veterans Affairs Dental Longitudinal Study. In an extensive simulation study, we show that our proposed method yields estimates with minimal relative biases and excellent coverage probabilities.  相似文献
