Could the way a dentist moves a tiny file ease root canal pain?
NCT ID NCT07714733
First seen Jul 20, 2026 · Last updated Jul 21, 2026 · Updated 1 time
Summary
This trial looks at whether changing how the dentist's tool moves during a root canal can reduce pain afterward. Adults with an infected lower premolar will get standard root canal treatment, but the file system will use either a continuous spin or a back-and-forth motion, with different stopping modes. Pain levels and painkiller use will be tracked for a week. The goal is to find a more comfortable way to do this common dental procedure.
