The Effect of Non-Surgical Periodontal Therapy on Glycosylated Hemoglobin HBA1C Levels for Type II Diabetes Mellitus in Libyan Patients: Retrospective Interventional Study

Background: The control of hyperglycemic levels in Diabetic patients reduces the risk of minor and major complications. It has been documented sever chronic periodontitis affects the glycemic control in patients with Diabetes. It has been reported by several clinical trials that treating chronic periodontitis in type II diabetic patients with phase I periodontal therapy reduces the levels of glycosylated hemoglobin of HBA1c by 0.4%. Aim: The aim of the present study is to observe the effect of non-surgical periodontal therapy on glycosylated hemoglobin levels in type II diabetic patients presented with chronic periodontitis. Results: Patients included in the study were recruited from Al Motamyaz private dental clinic. Forty-six patients with type II diabetes mellitus were included with different levels of severity for chronic periodontitis whom fit the inclusion criteria. All patients were treated by non-surgical debridement without the use adjunctive antibiotics. Full periodontal charting and HBA1c levels were recorded at baseline and three months after periodontal treatment. All clinical parameters including plaque score, bleeding score, and periodontal probing depths showed significant reduction at three months after non-surgical treatment with P value
