Pain relief after retreatment of a single-root tooth
Part of Mouth & dental clinical trials.
This study tests two different medications placed inside a tooth during a second root canal treatment (retreatment) to see which one causes less pain afterward. It aims to help people who need another root canal procedure feel more comfortable.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You must have had a root canal treatment that failed or didn't work.
- The affected tooth must have only one root (like front teeth or some premolars).
- You must be in good general health (no serious medical conditions).
