Objectives: The purpose of the study was to analyze the association between dyslipidemia and periodontitis in Korean adults aged 30 and older. Methods: We examined 3,992 subjects participating in the 2015 Korean National Health and Nutrition Examination Survey. Periodontal status was evaluated using the community periodontal index (CPI). People with 3 or 4 CPI codes were classified as the periodontitis group. For statistical analyses, chi-square test and logistic multiple regression were used. Results: The prevalence of periodontitis was higher in men, people aged 70 and over, people whose income status was among the lower 25%, and people whose educational level was high school or lower (p<0.001). The prevalence of periodontitis was higher in people who brushed their teeth twice or less, those who did not use interdental cleaning devices, those who did not have a dental checkup in the last 12 months, and those who had not drunk or smoked (p<0.05). The prevalence of periodontitis was increased with individuals whose BMI was ≥25 kg/m2 , those whose glycated hemoglobin was ≥6.5%, and whose lipid levels were higher or lower than the normal range. In the logistic regression model, an increase in triglyceride was found to increase the prevalence of periodontitis (p<0.05). Conclusions: The study suggests that dyslipidemia, especially hypertriglyceridemia, is a predictor of periodontitis.
