Comparing two types of crowns for back teeth in children
Part of Mouth & dental clinical trials.
This study compares two ways to fix cavities in children's permanent back molars: a special 'Hall' crown that is placed without numbing or drilling, versus a traditional crown. It aims to see which one works better and is more comfortable for kids.
Summary written for real people, not researchers, by Clin2.
Who can take part

- The tooth does not hurt or show signs of nerve damage (like pain to hot/cold or swelling).
- Your child has no allergy to nickel (which is in some dental materials).
- The tooth has a healthy root and bone around it on X-rays.
