Root canal showdown: which technique spares you the ache?
NCT ID NCT07290192
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study compares two ways to clean a tooth's root canal (step-back vs step-down) to see which one leads to less pain afterward. About 110 adults with a dead nerve in a single-root tooth will be randomly assigned to one method. Pain levels will be tracked for a week using a simple 0-10 scale. The goal is to find the gentler technique for patients.
