New root canal technique could mean less pain for patients
NCT ID NCT07357233
First seen Jan 24, 2026 · Last updated Jun 22, 2026 · Updated 18 times
Summary
This study tests a new way to do root canals that skips the manual step of scouting and widening the canal by hand. Instead, dentists use a special rotary file from the start. The goal is to see if this causes less pain after the procedure compared to the traditional method. The trial involves 34 adults with infected lower molars and will also measure pain-related chemicals in the blood.
