Abstract

Background: Diabetes mellitus and periodontitis are common diseases, there is a two-way relationship between oral health and systemic disease. Periodontal treatment improves glycosylated hemoglobin.In contrast, glycaemic control can make periodontal status better. Aim: The aim of the study was to evaluate the long-term results of periodontal treatment on clinical features and HbA1c in type 2 diabetes patients. Materials and Methods: A clinical trials study on 76 type 2 diabetes patients with mild and moderate periodontitis. Patiens were divided into two group. Scaling and root planning with Diode laser (SRP+DL) group: full-mouth SRP with Diode laser and Scaling and root planning (SRP) group: full-mouth SRP . Periodontal index and HbA1c were recorded at baseline and six month after treatment. Results: After 6 months, significant changes in periodontal index (p<0.01). HbA1c levels did not change significantly in both groups (p>0.05). Conclusion: The study shows that non-surgical periodontal treatment with/without diode laser change significantly periodontal health, but long-term result do not change HbA1c in type 2 diabetes patients.
