The aim of the present study was to investigate the association between periodontitis and chronic gastritis/peptic ulcer using a cross-sectional study design. The present prospective cohort study used epidemiological data from the Korean Genome and Epidemiology Study (KoGES) recorded from 2004 to 2016. Among 173,209 participants, 9983 with periodontitis and 125,336 with no periodontitis were selected. Histories of chronic gastritis and peptic ulcer between periodontitis and no periodontitis participants were analyzed. The participants were questioned around any history of hypertension, diabetes mellitus, hyperlipidemia, cerebral stroke, ischemic heart disease, periodontitis, body mass index, smoking, alcohol consumption, nutritional intake, and financial income. Chi-square tests, independent t-tests, two-tailed analyses were used in statistical analysis of the data. The adjusted odds ratio of chronic gastritis was 2.22 (95% confidence interval [CI] = 2.10-2.34, p < 0.001) and that of peptic ulcer was 1.86 (95% CI = 1.74-1.98, p < 0.001) in model 2. This study demonstrated that periodontitis was associated with an increased risk of chronic gastritis/peptic ulcer. These findings provide additional evidence for an association between periodontitis and chronic gastritis/peptic ulcer.
