Comparing two ultrasound tools for tooth pain after root canal
Part of Mouth & dental clinical trials.
This trial tests two different ultrasound methods used during root canal treatment to see which one reduces pain better afterwards. It focuses on people with a specific kind of tooth pain and infection.
Summary written for real people, not researchers, by Clin2.
Who can take part

- Need a root canal in a lower back molar (mandibular first molar) that hurts when you bite or tap it
- Have moderate to severe pain before treatment
- Tooth still responds to cold testing (pulp is alive)
