Effect of Non‐Surgical Periodontal Therapy on Glycemic Control in Patients with Type 2 Diabetes Mellitus

Background: The literature suggests that an alteration in glucose metabolism occurs as a result of antibacterial periodontal therapy. The objective of this study was to monitor the effect of non‐surgical periodontal therapy on glycemic control in patients with type 2 diabetes mellitus (DM). Methods: Thirty type 2 DM subjects with periodontitis were randomly divided into two groups. Group 1 (G1), 15 subjects, received one‐stage full‐mouth scaling and root planing (FMSRP) plus amoxicillin/clavulanic acid 875 mg; group 2 (G2), 15 patients, received only FMSRP. At baseline and after 3 months, the glycated hemoglobin (HbA1c) values, fasting glucose, and clinical parameters (with computerized probing and individualized acrylic stents) were recorded. Following therapy, the subjects were enrolled in a 2‐week interval maintenance program for 3 months. Results: After treatment, both groups showed clinical improvements.
