Objectives: The purpose of this study was to analyze the relationship between uncontrolled diabetes with periodontal disease (PD) among adults in the US.

Methods: The study sample from the 2009-2014 National Health and Nutrition Examination Survey data included 10,071 US participants aged ≥ 30 years in a probability weighted sample. We used the Centers for Disease Control and Prevention/American Academy of Periodontology’s standard to measure PD status by using means of a full-month oral examination at 6 sites per tooth for periodontal probing depth and clinical attachment loss. We used self-reported response to the diabetes questionnaire and laboratory report of HbA1c to assess the participant’s diabetes status (no diabetes, diabetes with HbA1c < 9%, diabetes with HbA1c ≥ 9%). Multiple logistic regression analysis was performed to examine the relationship between diabetes status with PD.

Results: Multiple logistic regression showed that PD was significantly associated with controlled diabetes (adjusted odds ratio (OR) = 1.32, 95% confidence interval (CI): 1.01 - 1.73, p <0.05) and uncontrolled diabetes (OR = 2.48, 95% CI: 1.52 - 4.04, p <0.001) after adjusting for covariates. PD’s protective factors of PD included annual dental visit, female gender, and college education. PD’s risk factors were smoking status, racial minorities, income <200% Federal Poverty Guidelines, and older age.

Conclusions: Uncontrolled diabetes was significantly associated with a higher risk of periodontal disease among adults in the US. Physicians should work with dentists to strongly recommend patients with diabetes to check their glycemic level and have an annual dental visit.
