Clinical research on correlation between periodontitis and diabetes

Objective: To evaluate the correlation between periodontitis and diabetes. Methods: We divided 114 patients with periodontitis and diabetes into 3 groups according to the level of blood glucose,and examined their CPITN and number of missing teeth.And then we divided these patients into 3 groups randomly. Group A was the experimental group received treatment not only on periodontitis but alsoon diabetes. Group B and group C were control groups which received treatment on periodontitis or on diabetes respectively. After 1 month,we evaluated the curative effect of periodontitis and diabetes in these 3 groups. Results: The CPITN in the group with blood glucose 7.0 mmol/L was significantly less than that in the other 2 groups (P0.05 and P0.01).The number of missing teeth in the group with blood glucose 12.1mmol/L was significantly more than that of other groups (P0.05).The curative effect of periodontitis in group A was better than that of other 2 groups (P0.05). Conclusion: There is a correlation between periodontitis and diabetes.
