Effect of Non-surgical Periodontal Therapy With and Without 0.2% Chlorhexidine Rinse on Metabolic Control of Type 2 Diabetic Patients

Background: The prevalence of periodontal diseases in patients with type 2 diabetes and improper glucose control is significantly higher. The aim of this study is to investigate the effect of scaling and root planning and chlorhexidine digluconate rinse on metabolic control in type 2 diabetic patients. Methods: A total of 60 patients with poorly controlled type 2 diabetes and moderate chronic periodontitis were selected, and randomly divided into three groups. We performed scaling and root planning in 2 test groups (T1, T2), with 0.2% chlorhexidine rinse used only for test group 2. Follow-up including one evaluation 3 months later and a visit 6 months later, was to evaluate glycemic control (FBS and HbA1c) and periodontal status (PI and CPI). Data were presented as mean ± standard deviation (SD) and analyzed using Student’s t test and Wilcoxon test in SPSS 20.0. Results: The mean changes in all variables in both test groups except FBS were significantly reduced (P <0.01). T2 group showed better results at 3-month evaluation. Conclusions: Non-surgical periodontal therapy improves periodontal health indicators and metabolic control in type 2 diabetic patients. Chlorhexidine is more effective on periodontal status and metabolic control in the short term.
