Root canal relief: study tests which fillings hurt less
NCT ID NCT07386197
First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study looked at 120 people who needed root canal treatment on their molars. Researchers tested different filling materials (bioceramic vs. resin-based) and techniques (cold vs. warm filling) to see which caused the least pain afterward. The goal is to help dentists choose options that make the procedure more comfortable.
