Laser vs ultrasound: which cleans root canals better?
NCT ID NCT07607028
First seen Jun 11, 2026 · Last updated Jun 22, 2026 · Updated 2 times
Summary
This small study tested two methods for cleaning infected root canals: ultrasonic activation and a 980-nm diode laser. Sixteen adults with dead (necrotic) teeth had their root canals cleaned with one of these methods. Researchers checked for leftover bacterial DNA to see which method worked better. The goal is to find the most effective way to reduce bacteria during root canal treatment.

What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
Active substance
3% sodium hypochlorite irrigation activated by ultrasonic or diode laser
What this could lead to
If one method proves better at removing bacteria, it could improve root canal success rates.
What could go wrong
This is a very small pilot study with only 16 participants, so results may not apply to all cases. It measures bacterial DNA, not actual infection outcomes.
