Gum treatment may help diabetes patients manage blood sugar
NCT ID NCT02563457
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study looked at whether treating gum disease (periodontitis) can improve blood sugar control in people with diabetes. 91 patients were randomly assigned to receive either gum treatment or no treatment (with treatment offered later). The main measure was change in hemoglobin A1c, a key blood sugar marker. The goal is to see if dental care can be a helpful addition to diabetes management.
