Pain Relief After Root Canal Retreatment
Part of Mouth & dental clinical trials.
This study tests two different ways of cleaning and treating a tooth that had a root canal treatment before. Researchers want to see which method causes less pain after the procedure.
Summary written for real people, not researchers, by Clin2.
Who can take part

This trial compares three different gentle motions used during a root canal to see which one causes the least pain afterward. If you need a root canal on a lower premolar that's infected, you might qualify.
This study tests whether using different electronic devices to measure tooth root length can reduce pain after a second root canal procedure. It is for people who had a root canal at least 4 years ago and now have a painless infection at the tip of the root.
This study tests whether cold therapy (cryotherapy) can reduce pain after re-treating a root canal infection. It aims to see if this treatment changes certain natural chemicals in the body (PGE2 and NGF) that are linked to pain.
This study compares two types of medications placed inside a tooth after root canal treatment to see which one reduces pain better. You'll be asked about your pain levels after treatment, and researchers will measure a pain-related substance in your saliva.
This study compares two different techniques for cleaning and shaping root canals (the nerve chambers inside teeth) to see which one causes less pain after treatment. If you have a dead nerve in a back lower tooth, this trial may help us understand the best way to treat it with minimal discomfort.
This trial compares two methods of cleaning a tooth's root canal to see which causes less pain after the procedure. It is for people with a specific type of tooth nerve pain (acute pulpitis) in a lower back molar.
