Comparing two root canal cleaning methods for less pain
Part of Mouth & dental, Pain clinical trials.
This study compares two common ways a dentist cleans and shapes the inside of a tooth during a root canal (the step-down technique vs. step-back technique) to see which one causes less pain after the procedure. If you have a single-rooted tooth with a dead nerve but no infection at the tip, you may be able to join.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You are between 18 and 65 years old.
- You are generally healthy (or have a well-controlled condition like high blood pressure).
- The tooth needing treatment is a single-rooted tooth (like a front tooth or premolar).
- The tooth has pulp necrosis (the nerve is dead), but no infection has reached the tip of the root yet.
- You have not had a root canal on this tooth before.
- You are not pregnant, breastfeeding, or a smoker.
