Laser vs. nano-chitosan gel for whitening dead teeth
Part of Mouth & dental clinical trials.
This study tests two methods to whiten teeth that have had root canal treatment. It compares using a diode laser with a special gel to see which works better for lightening discolored front teeth.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You have a front tooth that is discolored because the nerve died or had root canal treatment.
- The root canal was done at least 2 years ago.
- The discolored tooth must be one of your upper front teeth (central or lateral incisor).
- You cannot have any cavities or large fillings in those front teeth.
- You must not have active gum disease getting worse.

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 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.
