Laser zaps tooth infections better than sonic cleaners?
NCT ID NCT07387809
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study compares two methods to clean infected root canals during a single dental visit: laser-activated irrigation and sonic-activated irrigation. Sixty adults with chronic apical periodontitis (a tooth infection) will receive one of the two treatments. Researchers will measure pain levels over a week, check bacteria removal, and use 3D scans to see if the infection heals after one year. The goal is to find out if the laser method reduces pain and improves healing more than the sonic method.
What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
- Active substance
- Laser-activated irrigation (Er:YAG laser) and sonic-activated irrigation (polymer tip device)
- What this could lead to
- If successful, this could show that laser-activated irrigation is a more effective way to clean infected root canals, reducing pain and improving healing after a single dental visit.
- What could go wrong
- This is a small, early-stage study with only 60 participants, so results may not apply to everyone. The laser device is already used in dentistry, so the main question is whether it works better than existing methods.
