The purpose of this study was to investigate the prevalence of radiographic periradicular radiolucencies in endodontically treated and untreated teeth in patients with and without diabetes.


The records of 30 subjects with diabetes and 23 control subjects attending the Endodontic Graduate Clinic at the University of Florida, Gainesville, were reviewed. The number of teeth with root canal treatments with and without periradicular radiolucencies and the number of teeth without endodontic treatment but with periradicular lesions were recorded.


There were no main effects of sex, diabetes diagnosis, or age (the covariate) on the 3 outcomes of interest- nonsurgical endodontic treatment (NSE) with lesions, NSE without lesions, and no NSE with lesions. However, there were significant interactions between sex and diabetes diagnosis for both of the endodontic outcomes, NSE with lesions (F = 4.292; P <.05) and NSE without lesions (F = 4.241; P <.05). This meant that men with type 2 diabetes who had endodontic treatments were more likely to have residual lesions after treatment.


Type 2 diabetes is associated with an increased risk of ill response by the periradicular tissues to odontogenic pathogens.
