ClinConnect Summary

This clinical trial is investigating a new method to prevent tooth decay (caries) in children by using a special type of laser on the grooves of their back teeth, known as molars. The goal is to see if this laser treatment can help make these teeth more resistant to decay compared to the traditional method of applying fluoride varnish. The study will involve children aged 6 to 12 who have certain conditions in their teeth that make them eligible for the trial.

Participants will receive either the laser treatment or fluoride varnish on their molars, and the researchers will check the health of these teeth over a year to see which method works better. To be eligible, children must have fully erupted first permanent molars that are not severely decayed and must be in good overall health. Parents will need to provide consent and ensure that their child can follow the study’s procedures. This trial is currently recruiting participants, and it aims to discover if this laser treatment could become a routine way to help prevent cavities in children.
