Laser treatment for root canal retreatment healing
Treatments studied
Part of Mouth & dental clinical trials.
This trial tests whether a special laser (810 nm diode) can help heal infections around the root tip after a failed root canal. It is for people who have a single-rooted tooth that needs retreatment.
Summary written for real people, not researchers, by Clin2.
Who can take part
- Your tooth has a single root with a simple (type I) canal shape.
- You've had a root canal before that didn't heal properly.
- The X-ray shows a clear infection or dark area around the root tip (PAI score of 3 or 4).
- You haven't taken antibiotics in the last month.
- You are not pregnant or breastfeeding, and you have no serious medical conditions or bone diseases.
- The tooth can still be saved (no cracks, fractures, or resorption).

This trial tests if using a special laser (810 nm diode) to disinfect the tooth after a second root canal treatment can reduce pain and inflammation. It aims to help patients whose previous root canal failed and who have a small infection around the tooth root.
This trial tests if using ultrasound and a 980 nm diode laser together can reduce pain and kill bacteria better after a root canal. It may help if you have a tooth with an infection at the tip, but no symptoms.
This study compares different cleaning solutions used during root canal treatment to see which one reduces pain after treatment and has fewer bacteria. If you need root canal treatment, you may be able to join and help researchers understand the best way to care for infected teeth.
This study compares different medicines placed inside root canals between appointments to help heal infections. You'll have a tooth retreated (cleaned and filled again) and help researchers find which dressing works best.
This study tests if using a laser is better than the usual method for treating painful, inflamed teeth that still have a live nerve. The goal is to save the tooth and reduce pain without removing the nerve entirely.
This trial tests whether a nano-scale calcium hydroxide paste works better than standard treatments for tooth infections. If you have a permanent molar with signs of infection around the root tip, this study may be an option.
