ClinConnect Summary

This clinical trial is designed to compare two types of crowns used to fix damaged baby teeth, called primary molars: Bioflx crowns and zirconia crowns. The main goal is to find out which type of crown makes children and their parents happier with their dental care. The study will also look at how well each crown stays in place, how they wear down over time, and the health of the gums around them.

To participate in this trial, children between the ages of four to eight years old who are generally healthy and can cooperate during dental visits may be eligible. Their parents or guardians need to agree to the study and the follow-up visits. However, children with specific issues like poor oral hygiene, certain allergies, or serious problems with their teeth will not be included. If your child qualifies, they can expect to receive one of the two crown types and share their thoughts on their experience, helping researchers understand which option is better for young patients.
