Summary

This study tested whether using different modes on an electronic apex locator (a tool that measures tooth canal length) during root canal retreatment could reduce pain afterward. 144 adults with infected teeth were split into four groups: one used a standard locator, and three used a motor with special modes (reverse, slow down, or stop). Pain was tracked for a week. The goal was to see if these modes make retreatment less painful.
