Ice vs. spray: which chills root canal pain best?
NCT ID NCT07264829
First seen Jun 27, 2026 · Last updated Aug 26, 2026 · Updated 2 times
Summary
This study compares two ways of applying cold inside a tooth during a root canal to see which reduces pain better. Ninety adults with a painful, inflamed tooth nerve will be randomly assigned to receive either ice sticks, a cold spray, or no extra cold treatment. Patients will rate their pain and anxiety before, during, and after the procedure to find out which method works best.
