Could a common diabetes drug also fight gum disease?
NCT ID NCT07182123
First seen Jun 24, 2026 · Last updated Jun 26, 2026 · Updated 1 time
Summary
This pilot study will test whether a weekly injection of a GLP-1 receptor agonist (a type 2 diabetes drug) can improve gum health in 30 adults who have both periodontitis and diabetes. Researchers will measure changes in gum pocket depth, bleeding, and tooth mobility. The goal is to gather enough data to plan a larger, more definitive trial.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- GLP-1 receptor agonist (a diabetes drug that may also reduce gum inflammation)
- What this could lead to
- If it works, this could point toward a new way to treat gum disease using existing diabetes medications.
- What could go wrong
- This is a very small pilot study with only 30 people, not yet recruiting. It is designed to gather data for a future trial, not to prove effectiveness. Results may not apply to everyone.

Who can take part
This study's own entry requirements. Only the study team can say for certain whether you qualify.
Who is studied
Study participants will be recruited during routine care at the Clinical Division of Endocrinology and Diabetology, University Hospital Graz, where treatment is provided in accordance with current clinical guidelines. In line with the S2k guideline "Interrelationships between Periodontal Diseases and Diabetes Mellitus", patients receive standardized education on the bidirectional association between periodontitis and diabetes, as this relationship is regarded as clinically relevant. As part of recommended care, an annual periodontal examination is scheduled; accordingly, patients are referred from endocrinological diagnostics to the Clinical Division of Conservative Dentistry, Periodontology, and Prosthodontics for baseline periodontal assessment (Sanz, Ceriello et al. 2018).
