Direct Pulp Capping for Deep Cavities in Back Teeth
Part of Mouth & dental clinical trials.
This study tests a treatment where dentists cap (seal) an exposed tooth nerve in deep cavities of back teeth to see if it heals properly. This might help save your tooth instead of needing a root canal.
Summary written for real people, not researchers, by Clin2.
Who can take part
- Your cavity is very deep and goes all the way through the outer tooth layers, affecting only the back lower teeth (molars)
- Your tooth nerve is only mildly inflamed—it hurts when you eat cold or sweet foods, but pain stops within seconds after you stop eating
- Your tooth responds normally to cold and electric nerve sensitivity tests, and bleeds slightly when decay is cleaned out
- Your tooth has no swelling when tapped or pressed, no deep pockets around the gum, and a small X-ray score showing the tooth root area is healthy
- The exposed nerve area is very tiny (0.5–1 millimeter), and bleeding from the exposed nerve stops within 5 minutes

This study tests two ways to treat deep cavities that reach the nerve of the tooth, to see which helps the nerve heal better. It may be an option if you have a deep cavity in a lower molar and the nerve is still healthy.
This study compares two ways to treat deep cavities in lower back teeth when the nerve is exposed. The goal is to see which method better protects the nerve and avoids the need for a root canal.
This study tests two ways to treat a deep cavity that has reached the nerve of a back tooth, aiming to avoid a root canal. It compares placing a special material directly on the nerve versus removing a small part of the nerve, to see which works better.
This study looks at whether markers of inflammation in the dental pulp (the nerve and blood vessels inside the tooth) can predict how well a tooth-saving procedure called full pulpotomy works for molars with very deep cavities. If successful, this could help doctors choose the best treatment for severe tooth pain.
This study tests if removing only the top part of the damaged tooth nerve can save a deeply decayed molar. It is for people with moderate to severe toothache that doesn't stop, especially when lying down.
This study tests a less invasive way to treat deep cavities in baby molars by leaving some decayed tooth material and sealing it to help the tooth heal. It aims to see if this approach works well and avoids more invasive treatments.
