First seen Jun 25, 2026 · Last updated Jul 01, 2026 · Updated 3 times
Summary
This study looked at four different ways to activate the cleaning solution used during root canals: laser, sonic, ultrasonic, and simple needle irrigation. The goal was to see which method causes the least pain after the procedure and how much debris gets pushed out of the tooth. Forty adults with painful, inflamed lower molars took part, and their pain was tracked over time.

Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
What this could lead to
If successful, this could point toward a better way to clean root canals and reduce pain after the procedure.
What could go wrong
