Background: Current scientific evidence addressing the relationship between periodontitis and hypertension is limited to studies producing inconsistent results. Methods: All participants of an ongoing representative cohort of Puerto Rican elderly who were ≥70 years old and residing in the San Juan metropolitan area were invited to this cross‐sectional study. Periodontal probing depth (PD) and attachment loss (AL) were summarized using the Centers for Disease Control and Prevention and the American Academy of Periodontology definition for severe periodontitis (≥2 teeth with AL ≥6 mm and ≥1 tooth with PD ≥5 mm). Three repeated blood pressure (BP) measurements taken were averaged using a standardized auscultatory method. Information on hypertension history, use of antihypertensive medications, and potential confounders (age, sex, smoking, heavy and binge drinking, diabetes, use of preventive dental services, flossing, body mass index, consumption of fruits, vegetables, whole wheat bread, and high‐fiber cereal) was collected during in‐person interviews. High BP was defined as average systolic BP ≥140 mm Hg or diastolic ≥90 mm Hg. Multivariate logistic regression models were used to study the relationship between severe periodontitis, hypertension history, and high BP. Results: The study population comprised 182 adults. In multivariate analysis, there was no association between severe periodontitis and hypertension history (odds ratio [OR] = 0.99; 95% confidence interval [CI]: 0.40 to 2.48). Severe periodontitis was associated with high BP, with OR of 2.93 (95% CI: 1.25 to 6.84), after adjusting for age, sex, smoking, and binge drinking. This association was stronger when restricted to those with hypertension or taking antihypertensive medications: OR = 4.20 (95% CI: 1.28 to 13.80). Conclusion: The results of this study suggest that periodontitis may contribute to poor BP control among older adults. 相似文献

Recent case-control studies indicate that alcohol increases the risk of oral premalignant lesions (OPL) among tobacco users, but the independent association between alcohol and OPL remains unclear. We prospectively evaluated the association between alcohol consumption and the incidence of OPL. Participants were 41,458 men in the Health Professionals Follow-up Study. Alcohol consumption was assessed every 4 years using validated food frequency questionnaires. We confirmed clinically or histopathologically diagnosed OPL events occurring between 1986 and 2002 by medical record review (193 cases). Multivariate-adjusted relative risks of OPL were calculated from Cox proportional hazards models. With detailed control for tobacco and other variables, multivariate relative risks (95% confidence intervals) were 1.7 (0.9-3.2) for drinkers of 0.1 to 14.9 g/d, 2.9 (1.5-5.6) for 15 to 29.9 g/d, and 2.5 (1.3-5.1) for > or =30 g/d, compared with nondrinkers. Approximately one additional drink per day (12.5 g) was associated with a 22% increase in risk (P < 0.001). The associations did not vary by beverage type, frequency, or consumption with meals. Results were similar when restricted to cases of oral epithelial dysplasia. Alcohol increased OPL risk in never-users of tobacco as well as in past or current users. An interaction between alcohol and tobacco was apparent by their more-than-additive joint effects. Alcohol is an independent risk factor for OPL, regardless of beverage type or drinking pattern. Recommendations to reduce alcohol intake have the potential to reduce incidence of OPL in nonsmokers and smokers alike. 相似文献

Abstract A meta-analysis was performed on 5 randomized controlled trials comparing surgical with non-surgical treatment for periodontal disease. The specific procedures considered were the modified Widman flap compared with scaling and root planing or curettage with anesthesia. We chose the most consistently reported outcomes, pocket depth and attachment level, for analysis. At 1 year of follow-up, surgical treatment reduced pocket depth more than non-surgical for all initial levels of disease, hut by 5 years, only the deepest initial pockets (>7 mm) showed significant improvement over non-surgically treated teeth (0.51 mm reduction, p<0.01). Attachment level showed significantly better early results for non-surgical treatment for less diseased teeth, but by 5 years, all significant differences had disappeared. We computed quality scores following a method described by Chalmers. The mean quality score for study data analysis and presentation was 0.37±0.009 and for the study protocol, the mean quality score was 0.19±0.002. We find that this metaanalysis supports findings relating response to therapy with initial level of disease severity. We also find that the choice of outcome measure influences the choice of therapy, with surgical therapy providing greater benefit for probing depth and non-surgical therapy providing greater benefit for attachment level. These results must be viewed, however, in light of the low quality scores of the evaluated studies and the potential for bias due to lack of blinding, the small mean treatment differences, and the observer measurement variability. 相似文献
