There is a high prevalence of dental loss among patients with diabetes. A cross-sectional study evaluated patients with diabetes who were presenting themselves for routine clinic visit, with an investigator-administered questionnaire. Data were collected on demographics, dental history, duration, control and complications of diabetes.

Among 202 subjects, 100 were female, mean age: 58.9 ± 13.2 years, duration of diabetes: 15.8 ± 11.0 years, and hemoglobin A1c: 7.7 ± 1.6%. Thirty-one patients (15.3%) had lost all their teeth and only 13 (6.4%) had all 32 of their natural teeth. Using multiple linear regression, older age (β= - 0.146; 95% CI: - 0.062 to - 0.230), not flossing (β= - 3.462; 95% CI: - 1.107 to - 5.817), and presence of diabetic retinopathy (β= - 4.271; 95% CI: - 1.307 to - 7.236) were significant predictors of dental loss.

Study result shows that dental loss is common in patients with diabetes and is associated with older age, diabetic retinopathy and not flossing. In order to reduce dental loss among patients with diabetes, regular flossing should be emphasized as an important component of dental care.
