This study radiographically analyzed the prevalence of root canal treatment (RCT) and apical periodontitis (AP) in type 1 diabetes mellitus (T1DM) and nondiabetic individuals and its association with the history/current status of T1DM.
In a cross-sectional paired study, the radiographic records of 50 individuals with T1DM and 100 age- and sex-matched nondiabetic subjects were examined. The presence of RCT and AP was evaluated. Information regarding the history and current status of T1DM was collected from the medical records of each patient.
One or more RCTs were found in 76% and 44% of diabetic and nondiabetic subjects, respectively (P = .000). AP in 1 or more teeth was found in most T1DM patients (58%) and in 15% of the control subjects (P = .000). One or more RCTs associated with AP were found in 52% and 8% of T1DM and nondiabetic subjects, respectively (P = .000). Bivariate logistic regression analyses suggested that RCT (odds ratio [OR] = 10.435, P = .000), AP (OR = 3.508, P = .011), and RCT + AP (OR = 7.220, P = .000) were significantly associated with the presence of T1DM. Multivariate logistic regression showed that among T1DM individuals, there is an association between 11–15 years of diagnosis time and at least 1 RCT (OR = 46.316, P = .038) and an association between T1DM control and at least 1 tooth with AP (OR = 15.611, P = .016).
RCT, AP, and RCT with AP were more prevalent in individuals with T1DM than in nondiabetic individuals. RCT and AP were associated with the presence of T1DM, specifically RCT with diagnostic time and AP with glycemic control.
