Does nonsurgical periodontal therapy improve glycemic control?

Based on included systematic reviews and limitations within the study, nonsurgical periodontal therapy is an effective treatment modality in glycaemic control in diabetic patients in terms of HbA1c reduction both at 3 months and 6 months follow-up. The adjunctive therapies like antibiotic administration whether local or systemic and use of lasers with NSPT does not show statistically significant differences as compared to NSPT alone. However, these findings are based on analysis of available literature based on systematic reviews on this subject.
