Comparing cleaning methods for infected molar retreatment
Part of Mouth & dental, Pain clinical trials.
This study compares different ways to clean and disinfect a molar tooth that had a root canal before but now has a new infection. You may be a good fit if you have a back tooth with a lingering infection that needs retreatment.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You need a molar tooth that has already had a root canal but now has a new infection (with a pocket of infection at least 3 mm wide seen on X-ray or 3D scan).
- The original root canal must have been done at least 2 years ago, or more than 1 year if you have symptoms like pain or swelling.
- You must not have taken any antibiotics in the last 3 months.
- You cannot have any serious health issues (like uncontrolled diabetes, autoimmune disease, or cancer treatment) that could affect healing.
- You must be able to read and understand English to give consent.
