| Summary: | Context: In the recent years, a two-way correlation has been postulated between periodontitis and systemic conditions. One such condition is diabetes mellitus (DM). Several studies have demonstrated a close relationship between DM and chronic periodontitis. Aims: To assess the effect of periodontal therapy and scaling and root planing (SRP) on the metabolic control in type 2 DM patients with chronic periodontitis based on the estimation of glycated hemoglobin (HbA1c). Settings and Design: A prospective, comparative, clinical study was performed on 50 patients suffering from type 2 DM with moderate, generalized chronic periodontitis. The study period was 6 months. Type 2 moderately controlled diabetic patients with glycated hemoglobin values within the range of 6-8% were selected. Patients with major diabetic complications, history of any antibiotic intake or periodontal treatment within the last 4 months, and smoking habits were excluded. Materials and Methods: The parameters recorded were gingival index (GI), plaque index (PI), sulcus bleeding index (SBI), probing pocket depth (PPD), clinical attachment level (CAL), and glycated hemoglobin. The recordings were done at baseline and 6 months after scaling and root planing procedures. HbA1c was measured by NycoCard Reader. Statistical Analysis Used: Karl-Pearson coefficient test, Z-test, and paired t-test. Results: Reductions in all the clinical parameters were observed and were found to be statistically significant (P < 0.005). Conclusions: Scaling and root planing resulted in a statistically significant reduction in the clinical parameters and HbA1c. So, periodontal treatment should be included in the management of diabetic patients.
