Effect of periodontal treatment on the blood parameters of individuals with diabetes mellitus

OBJECTIVE: This study aimed to evaluate diabetic individuals with chronic periodontitis who underwent periodontal treatment using clinical parameters and blood tests for fasting glycemia and glycated hemoglobin. MATERIAL AND METHODS: A total of 146 patients with diabetes were initially evaluated. After adopting the inclusion and exclusion criteria, 63 patients were included in the diabetic group (DG). The control group (CG) consisted of individuals with a similar age group to the DG group, a diagnosis of chronic periodontitis, and without systemic involvement. Periodontal clinical parameters and blood tests for fasting glycemia and glycated hemoglobin were performed before periodontal treatment (T1) and 90 days after (T2) treatment. RESULTS: For plaque index and bleeding index, there was a significant difference between the times in both groups. Significant reduction in the percentage of pockets with PD ≥ 6mm after periodontal therapy in both groups. The blood test showed a significant difference in DG group, for fasting glycemia in T1 mean of 168.8 mg/dl and in T2 of 153.1 mg/dl and glycated hemoglobin in 7.6% in T1 and 7.3% in T2 (p ≤ 0,05). CONCLUSION: Non-surgical periodontal therapy improved blood parameters of fasting glucose and glycated hemoglobin in individuals with type 2 diabetes mellitus after treatment.
