Saliva and tissue markers for long-term root canal infection
Part of Mouth & dental clinical trials.
This study looks at certain markers in your mouth that might be linked to a chronic (long-lasting) infection after a root canal. By checking these markers, researchers hope to better understand healing and possibly improve future treatment — so it could help you by giving you more insight into your own condition.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You must be a man between 18 and 35 years old.
- You must have had a root canal on a front tooth or a single-rooted premolar at least 4 years ago.
- There must be a small infection (under 1 cm) at the root tip, rated as moderate on the Periapical Index (PAI) scale.
- You cannot have taken antibiotics or anti-inflammatory drugs in the past month.
- Your gums must be generally healthy — no severe gingivitis, periodontitis, or deep pockets (over 3 mm).
- You cannot have diabetes, blood disorders, or be pregnant during the study, and you must not need antibiotic protection before dental work.

This study looks at certain proteins in the fluid around teeth and inside the tooth to see if they can tell the difference between healthy teeth and teeth with severe pulp inflammation (pulpitis). It may help find better ways to diagnose tooth pain.
This study looks at which factors can change how well root canal (endodontic) treatment works. It may help improve future care by understanding what leads to better healing.
This study tests whether different ways of activating the immune system during root canal retreatment affect levels of certain immune markers (TLR9, IL6, IL10, TNF-alfa) in people with type 2 diabetes. If you need a repeat root canal on a front tooth or lower premolar, you may be able to join.
This study looks at special proteins in the fluid around your gums to understand how gum disease develops in young people. By studying these markers, researchers hope to better understand and treat gum inflammation.
This study looks at markers of bone damage and stress in people with gum disease around dental implants (peri-implantitis). It aims to understand how the body responds, which could help improve treatment.
This study looks for new markers in the body that could help diagnose gum disease. It's for adults with mild gum problems who haven't had recent dental treatment or antibiotics.
