Comparing two treatments for painful lower back teeth
Part of Mouth & dental clinical trials.
This study tests two newer ways to treat a painful, infected tooth (pulpitis) in lower back molars. They compare a special gel (chitosan hydrogel) against a natural blood-clot concentrate (platelet-rich fibrin) to see which helps the tooth heal better and avoids more invasive treatments.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You must have pain in a lower back tooth (molar) that is fully grown and not a baby tooth.
- The tooth should still react to cold – for example, it hurts briefly when you drink something cold.
- You should be in generally good health, with no serious medical conditions that could slow healing.
- The tooth should be repairable (restorable) and not have severe gum disease, cracks, or splits.
- You must be willing to attend follow-up visits for about 6 months after the treatment.
