Root canal showdown: bleach vs. chlorhexidine – which hurts less?
NCT ID NCT07453160
First seen Mar 05, 2026 · Last updated May 16, 2026 · Updated 9 times
Summary
This study compares two common root canal cleaning solutions—chlorhexidine and sodium hypochlorite (bleach)—to see which one leads to less pain the day after the procedure. About 90 adults needing a root canal will be randomly assigned to one of the two solutions. Participants will rate their pain 24 hours later using a simple scale. The goal is to help dentists choose the gentler option for patient comfort.
