Direct vs. indirect pulp capping for deep cavities in lower molars
Part of Mouth & dental clinical trials.
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.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You are 18 years or older.
- You have a deep cavity in a lower back tooth (molar) that reaches deep into the dentin (the layer below the enamel).
- The tooth is still alive (responds to cold or electric tests).
- The dentist determines the nerve is mildly inflamed (moderate pulpitis).
- X-rays show no major infection around the root tip (PAI score 2 or less).
- You have healthy gums with no deep pockets or loose teeth.
- During cavity cleaning, the nerve is exposed only after removing all decay (not before).
- You have not taken painkillers in the last week or antibiotics in the last month.
- You do not have serious health issues like diabetes, heart disease, or a weakened immune system.

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 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.
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 compares two materials used to treat deep cavities in permanent molars without causing pain. The goal is to see which material better protects the tooth's nerve and helps the tooth heal, potentially avoiding the need for a root canal.
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.
This study tests whether a newer, less invasive treatment called full pulpotomy (removing only the infected pulp and sealing the tooth) works as well for teeth with an infection at the root tip as it does for teeth without that infection. It aims to see if this approach can save your tooth and avoid a root canal.
