Abstract

This nationwide cross-sectional survey investigated the association between periodontal disease and self-reported systemic health in periodontal patients who regularly visited private dental clinics in Japan. Data from 999 patients of 444 dental clinics were analyzed; the patients were aged 40 years or older, regularly visited dentists, and had diagnosed periodontal disease (defined as two or more teeth with a clinical attachment level ≥6 mm). Medical history was collected with a self-reported questionnaire. Number of teeth with a probing pocket depth (PPD) ≥5 mm was used to define periodontal status, and the highest quartile was used as the dependent variable. A Poisson regression model showed that histories of diabetes and hypertension were associated with a larger number of teeth with a PPD ≥5 mm (diabetes: prevalence rate ratio [PRR] 1.36, 95% confidence interval [CI] 1.00-1.85; hypertension: PRR 1.27, 95% CI 1.02-1.58) after adjusting for potential periodontal risk factors. These findings suggest that diabetes and hypertension are associated with worse periodontal disease. Dentists should confirm the diabetes and hypertension status of patients who receive maintenance care, because these conditions could affect periodontal management of patients.
