Could vinegar and a laser beat tooth infections in diabetes?
NCT ID NCT07549373
First seen Jun 24, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study tests whether a diode laser, apple cider vinegar, or the herb Gymnema Sylvestre can better disinfect root canals in people with type 2 diabetes who have a tooth infection called apical periodontitis. Ninety participants will be split into groups receiving different combinations of these treatments during root canal therapy. The goal is to see which approach best kills bacteria and reduces pain.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- 940nm diode laser, apple cider vinegar, Gymnema Sylvestre
- What this could lead to
- If successful, this could point toward a simple, low-cost way to improve root canal disinfection in diabetic patients, reducing infection and pain.
- What could go wrong
- This is a small, early-stage trial (90 participants) testing multiple interventions. Results may not apply to all patients, and the long-term effectiveness is unknown.
