To the Editor Dr Engebretson and colleagues1 reported that nonsurgical periodontal treatment did not reduce levels of glycated hemoglobin (HbA1c) among individuals with type 2 diabetes in a randomized clinical trial (RCT). This contrasts with the results of an RCT by Sun et al,2 in which periodontal treatment was found to improve glycemic control, lipid profile, and insulin resistance and reduce systemic inflammation among individuals with type 2 diabetes. The intervention tested by Sun et al consisted of nonsurgical periodontal treatment plus administration of systemic antibiotics and, where indicated, surgical periodontal treatment and tooth extraction.
