First seen Jan 11, 2026 · Last updated May 23, 2026 · Updated 22 times

Summary

This study looks at how long dental sealants last on back teeth that are either healthy or have very early signs of decay. About 420 children and teens aged 7 to 18 will get sealants, and researchers will check them after 3, 6, and 12 months. The goal is to find out if sealants stay on better for healthy teeth or early cavity teeth, helping dentists plan better cavity prevention.
