AimTo assess the effectiveness of serum titres of antibody to Porphyromonas gingivalis in the prediction of periodontitis progression in a community-dwelling adult population. Materials and MethodsThis 4-year follow-up cohort study included 183 Japanese individuals (75 men and 108 women) aged 40-49years. The clinical attachment level was measured at two sites on all teeth present at baseline and follow-up, and periodontitis progression was defined as progression in attachment loss of 3mm at 2 measurement sites. Serum titres of antibody to Porphyromonas gingivalis were evaluated at baseline and served as the primary predictor variable for periodontitis progression. ResultsPeriodontitis progression was found in 8.7% subjects. In a multivariate logistic regression model, higher titres of antibody to Porphyromonas gingivalis and male gender were significantly associated with greater odds of periodontitis progression, even after adjustment for other confounding variables (titres of antibody to Porphyromonas gingivalis per 10 units: odds ratio, 1.66; 95% confidence interval, 1.16-2.36; male gender: odds ratio, 4.13; 95% confidence interval, 1.20-14.27). ConclusionsElevated serum titres of antibody to Porphyromonas gingivalis may be a risk factor for periodontitis progression.
