Glycated Hemoglobin Levels and Prevalence of Apical Periodontitis in Type 2 Diabetic Patients

Abstract Introduction The purpose of this investigation was to study the possible association between the prevalence of apical periodontitis (AP) and the glycemic control of type 2 diabetic patients. Methods In a cross-sectional study, the radiographic records of 83 type 2 diabetic patients were examined. Glycemic control was assessed by the mean glycated hemoglobin (HbA1c level). AP was diagnosed as radiolucent periapical lesions (RPLs) using the periapical index score. The Student t test, chi-square test, and logistic regression analysis were used in the statistical analysis. Results Based on the HbA1c levels, 2 groups of diabetic patients were established: the HbA1c good control group (GCG, n = 24, HbA1c
