The expression levels of genes associated with apoptosis and OGG1 in the gingival connective tissue of diabetic individuals with chronic periodontitis was higher than in nondiabetics with identical periodontal conditions. Thus, the signals and function of the genes examined in this study can be important and useful factor for further investigation in the treatment of patients with both periodontitis and diabetes.
Kalbassi et al. (Thu,) studied this question.
