First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study tests two ways to clean a tooth during a root canal: laser-activated irrigation and passive ultrasonic irrigation. Researchers want to see which method leads to less pain and better quality of life afterward. 90 adults with infected or damaged permanent teeth are taking part, and their outcomes will be checked after one year.
