The effect of periodontal and prosthodontic therapy on glycemic control in patients with diabetes.

PURPOSE

To evaluate the effect of periodontal and prosthodontic therapy on glycated hemoglobin A(HbA1c) level in patients with diabetes.

MATERIALS AND METHODS

This is a retrospective study of 70 patients suffering from diabetes who visited the Kyungpook National University Hospital between January 2016 and May 2018. Patients underwent medical evaluation for their routine check-up, which includes laboratory test for HbA1c levels. Among the 70 patients, 35 patients also visited Kyungpook National University Dental Hospital during the same period to receive periodontal and prosthodontic therapy, while the other 35 patients did not receive such therapy. The HbA1c levels were compared before and after periodontal and prosthodontic therapy. Comparisons between groups and within groups were performed using independent t-test.

RESULTS

The HbA1c levels in the group who have received periodontal and prosthodontic therapy decreased from 7.2 to 6.7 (=.001). The HbA1c levels in the control group decreased from 7.2 to 7.1 (=.580). The difference in changes between the two patient groups was statistically significant (=.011).

CONCLUSION

Periodontal and prosthodontic therapy can be effective on glycemic control in patients with diabetes.
