Clinical ResearchType 2 Diabetes Mellitus and the Prevalence of Apical Periodontitis and Endodontic Treatment in an Adult Brazilian Population
Section snippets
Materials and Methods
Individuals seeking routine dental care and attending the School of Dentistry of the Estácio de Sá University for the first time were selected to take part in this study. The study group was composed of 30 type 2 diabetic individuals (18 women and 12 men), with ages ranging from 40 to 69 years (mean, 58.2 ± 8.2 years). Controls were age and sex matched with diabetics so that there were 2 nondiabetic individuals for each diabetic patient. Ages for the 60 control individuals ranged from 41 to 70
Number of Teeth and Prevalence of Root Canal Treatment
The average number of teeth per individual in the diabetic group was 21.7, whereas in the control group it was 22.8 (Table 1). This difference was not statistically significant (P > .05). Of the diabetics, 77% displayed 1 or more teeth with root canal treatment, with an average of 2.8 root canal–treated teeth per patient. Of the nondiabetic subjects, 87% presented endodontic treatment in at least 1 tooth, with an average of 3.4 treated teeth per individual. No significant differences were
Discussion
Because there are so far few studies in the literature reporting on diabetes as a disease modifier in endodontics, this cross-sectional study was conducted to investigate the prevalence of AP and endodontic treatment in type 2 diabetic individuals. A cross-sectional design was used because of the advantage of allowing the inclusion of a large number of individuals. Even so, the number of diabetic individuals gathered was not so large but was comparable with previous studies on this same issue 13
