Background: This study examines the association between periodontitis, diabetes (DM), and glycemic control. Methods: National Health and Nutrition Examination Survey data for 2009 to 2012 were analyzed. Periodontitis status of each participant was assessed using the full-mouth periodontal examination protocol, classified using the Centers for Disease Control and Prevention and the American Academy of Periodontology surveillance case definition for total periodontitis. Self-reported DM status was defined as yes or no. Glycemic control was assessed using glycohemoglobin data at cutoff points of 7.0%, 7.5%, 8.0%, 8.5%, and 9.0%. Descriptive statistics and logistic regression analyses were performed, and all analyses were adjusted for the survey design. Results: Overall, 7,042 adults >= 30 years old with complete data were included in the study. The mean glycohemoglobin levels for individuals with and without periodontitis were 5.9% and 5.6%, respectively, and increased to 7.4% and 7.0% for participants with DM. The majority of participants with and without periodontitis were aged 50 to 64 and 35 to 49 years (37.4% versus 44.5%), respectively. In the bivariate analysis, several demographic factors were significantly associated with having periodontitis, including self-reported DM status and glycemic control. In the multivariate analysis, demographic factors, glycohemoglobin cutoff values of 8.0%, 8.5%, and 9.0%, and mean glycohemoglobin level remained significant, but self-reported DM status was not. Conclusion: This study demonstrates that glycohemoglobin and demographic factors are significantly associated with periodontitis, but not self-reported status.
