Comparing two ways to place MTA in root-end surgery for back teeth
Part of Mouth & dental clinical trials.
This study compares two ways of placing a special filling material (MTA) at the root tip during a surgical procedure called apicoectomy (removing the tip of the root). One method is done from the top of the tooth (orthograde), and the other is done from the bottom (retrograde). The goal is to see which method works better for saving a tooth with a persistent infection after a root canal.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You are between 18 and 55 years old.
- You have a back tooth (molar or premolar) with an infection or cyst at the root tip that is at least 5 mm in size.
- Previous root canal treatment failed, or non-surgical retreatment was not possible.
- The tooth does not have a root that is too curved (less than 10 degrees).
- You are in good overall health (no uncontrolled diabetes, high blood pressure, liver/kidney disease, or bleeding disorders) and are not taking blood-thinning medications.
- You have a good seal on the tooth (no leakage) and healthy gums around the tooth.

This trial compares two ways of doing a special tooth surgery (endodontic microsurgery) to see if using a high-magnification microscope helps you feel better after the procedure. If you have a tooth that still hurts or stays infected after a previous root canal, this study might be for you.
This study tests a gum surgery technique (guided tissue regeneration) to help heal teeth that have both gum disease and a failed root canal. It looks at how well the tooth heals and how it affects your daily life.
This trial tests whether using a bone graft (allograft) together with your own blood concentrate (iPRF) and a collagen membrane helps heal the bone and gum around a tooth with a long-standing infection. It might be a good option if you have a tooth that keeps getting infected despite a root canal and has a deep pocket on the cheek side.
This study compares two different root canal filling materials used during a second root canal treatment (retreatment) for teeth with an infection at the root tip. The goal is to see if one material is better at healing the infection and saving the tooth.
This study tests two different ways to do a root canal on a tooth with an infection at the tip of the root. It aims to find which method causes less pain after the procedure.
This study tests a gentler way to clean and fill infected lower back teeth (molars) with dead nerves. It aims to see if this minimally invasive approach can help save the tooth and reduce infection.
