Background and Objective:  Several studies have shown that periodontitis can complicate the severity of diabetes by worsening the degree of glycemic control. The purpose of this study was to determine the effect of full-mouth tooth extraction on glycemic control among type 2 diabetic patients.

Material and Methods:  A total of 58 patients with type 2 diabetes mellitus and advanced periodontitis who were requiring extraction of all remaining teeth were randomized consecutively into treatment (full-mouth tooth extraction) and control groups (no treatment). Eight patients were lost to follow-up or reported use of antibiotics, leaving 50 patients to be included in the analysis. All patients had all their remaining teeth in a hopeless condition. Relevant data were collected, and glycosylated hemoglobin (HbA1c) and fasting blood glucose levels were measured at baseline and at follow-up times of 3 and 6 mo.

Results:  At baseline, the mean (SD) HbA1c level was 8.6% (1.24) in the treatment group and 7.7% (0.87) in the control group. In the treatment group, the mean HbA1c level decreased significantly from 8.6% at baseline to 7.4% after 3 mo of denture treatment, and continued to decrease to 7.3% after 6 mo. In the control group, the mean HbA1c decreased from 7.7% at baseline to 7.5% after 3 mo, and remained almost the same after 6 mo. After adjusting for the baseline HbA1c, the mean reduction in HbA1c after 3 mo in the treatment group [1.23% (0.79)] was significantly higher than the mean reduction in the control group [0.28% (0.87)].

Conclusion:  Full-mouth tooth extraction resulted in an improvement in glycemic control among diabetic patients. Large-scale multicentre clinical trials are needed to confirm the current evidence.
