Reduction of HbA1c levels following nonsurgical treatment of periodontal disease in type 2 diabetics

Objectives: A study was made of the effect of nonsurgical periodontal treatment upon blood glucose control in type 2 diabetics with periodontal disease. Study design: A pre-post repeated measures analytical design was used, with a PubMed search of the related articles published up until December 2008. Results: The improvement in glycosylated hemoglobin (HbA1c) after nonsurgical periodontal treatment on comparing the baseline (8.0290±1.5539) and final values (7.7806±1.5636) was 0.2483±0.1171, and proved statistically significant (p=0.042). Conclusions: A decrease in HbA1c was observed after treatment, thus indicating improved blood glucose control in type 2 diabetics with periodontal disease
