Summary

This study tested three methods of keeping teeth dry while applying protective sealants to prevent cavities in children's permanent molars. Thirty children at high risk for cavities took part, and each method was compared for how long it took, how well the sealant stayed on after 6 and 12 months, and which method children preferred. The goal was to see if a newer tool called Dry-Shield could be a more comfortable and practical option than the standard rubber dam or cotton rolls.
