Comparing two filling materials for tooth retreatment
Part of Mouth & dental clinical trials.
This trial tests whether a newer material (MTA) works better than the standard one (gutta-percha) for re-treating a tooth that has an infection at the tip of the root (called an apical lesion). It may help people who need a second root canal procedure.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You must be at least 18 years old
- You must be in good general health (ASA I or II)
- You need a non-surgical second root canal on a tooth that has a small infection at the root tip (no bigger than 10 mm on x-ray)
- The root canal space at the tip must be small enough to fit a size 50 file
- Your tooth must not have gum disease or loose teeth
- You cannot be a smoker, and your tooth must have enough healthy structure left for treatment

This study compares three materials used to protect the nerve inside a deep cavity. If you have a deep cavity in a live tooth, you may be able to join and help find which material works best.
This trial tests two materials used to protect the nerve in deep cavities, comparing a newer calcium-based material to a standard one. It may help patients with a reversible, mild toothache that stops quickly.
This study tests a new material for filling root canals after cleaning out an infection. It aims to see if the material helps the tooth heal successfully. You may qualify if you have an infected tooth that has never had a root canal before.
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.
This trial compares two different materials used to treat the inner part of a decayed molar tooth when the nerve is inflamed but still alive. The study tests whether a natural plant-based material works as well as the standard treatment (MTA) to save your tooth.
This trial tests how well different materials help heal a small hole (perforation) in the root of a lower molar tooth. It may help if you have this type of tooth injury and are generally healthy.
