ClinConnect Summary

This clinical trial is studying two different materials used in a dental procedure called pulpotomy, which helps save children's teeth that have deep cavities but are still healthy. The researchers want to compare potassium nitrate mixed with a type of dental cement (polycarboxylate) and mineral trioxide aggregate (MTA) to see which one works better in keeping the tooth healthy until it naturally falls out to make way for permanent teeth. This study is important because it aims to avoid removing the entire pulp (the soft tissue inside the tooth) while still treating the tooth effectively.

To participate in this trial, children aged 4 to 7 years who are in good health and have certain types of cavity issues in their primary molars may be eligible. They should not have any signs of pain, swelling, or other serious dental conditions. If enrolled, children will receive one of the two treatments and will need to come back for follow-up visits to monitor how well their tooth is healing. This study is not yet recruiting participants, but it aims to help improve dental care for young children with similar dental issues in the future.
