Periodontitis Prevalence and Severity in Indonesians With Type 2 Diabetes

Background: The prevalence of diabetes mellitus type 2 (DM2) in Indonesia is high and still rising. Periodontitis is associated with DM2. No study has investigated this association in Indonesia, nor has any study investigated this association using a variety of methods to operationalize periodontitis. The present study compares prevalence and severity of periodontitis in patients with DM2 to healthy controls, using different methods to operationalize periodontitis. Methods: A total of 78 subjects with DM2 and 65 healthy control subjects underwent a full-mouth periodontal screening assessing probing depth, gingival recession, plaque index, and bleeding on probing. Using these measurements, the prevalence and severity of periodontitis was operationalized in various ways. Differences in the prevalence and severity of periodontitis between subjects with DM2 and healthy subjects were analyzed using univariate analyses. In regression analyses, the prevalence and severity of periodontitis were predicted on the basis of DM2 presence, controlling for confounders and effect modification. Results: Prevalence of periodontitis was significantly higher in subjects with DM2 compared to healthy subjects, showing odds ratios of 5.0 and 6.1. Likewise, periodontitis severity was significantly higher in subjects with DM2. Conclusion: Indonesian subjects with DM2 had more prevalent and more severe periodontitis than healthy Indonesian subjects, independent of confounding factors or the methods used to operationalize periodontitis.
