Laser disinfection for failed root canal treatment
Treatments studied
Part of Mouth & dental, Pain clinical trials.
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.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You have a single-rooted tooth (like a front tooth or premolar) with one main root canal.
- You had a root canal treatment that didn't work and now needs to be redone.
- You have a small infection (called a periapical lesion) around the root tip, seen on an X-ray.
- You have no pain, swelling, or tenderness when pressing on your tooth or gums.
- You have not taken antibiotics in the last 3 months.
- You are not pregnant or breastfeeding.

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.
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 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 special anti-inflammatory gel (diclofenac sodium) placed inside the tooth can help treat an infection at the root tip. It is for adults with a restorable tooth and no allergies to the medication.
This trial tests different ways to flush and clean inside a tooth during root canal treatment. It aims to see which method best reaches deep into the tooth and reduces bacteria.
