Abstract

Diabetes mellitus (DM) with poor glycemic control is often linked to oral manifestations. This study aimed to investigate the association between dental caries (DC) and glycated hemoglobin (HbA1c) among patients with type 2 DM (T2DM). A health center-based cross-sectional study was conducted comprising 91 eligible patients with T2DM (21 males and 70 females) with a mean age (± standard deviation) of 61.49 ± 9.71 years. A structured interview, screening for DM-related factors, and oral examination were performed. Serum HbA1c levels were used as an index for glycemic control. A comparison between patients with controlled T2DM, i.e., HbA1c ≤7.0% (n = 46), and uncontrolled T2DM, i.e., HbA1c >7.0% (n = 45), showed significant differences in mean values of decayed teeth (DT) (P = 0.045); missing teeth (P = 0.002); and decayed, missing, and filled teeth (DMFT) index (P < 0.001). Results of multiple linear regression analysis revealed that the number of DT was significantly correlated with serum HbA1c levels (95% confidence interval [CI] 0.173 to 0.972, P = 0.005). Furthermore, DMFT index values and serum HbA1c levels (95% CI 0.532 to 1.658, P < 0.001) showed a significant association. This study provides substantial evidence on the association between DC indicators and serum HbA1c levels.
