Which dental sealant keeps Kids' teeth Cavity-Free longer?
NCT ID NCT07143253
First seen Jun 26, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study tests two different dental sealants—a resin-based and a glass ionomer-based—on partially erupted permanent molars in children aged 10-15. The goal is to see which one lasts longer and prevents cavities better over one year. Forty healthy children will each get both types of sealants on different teeth, and dentists will check them at 3, 6, and 12 months.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- dental fissure sealants (hydrophilic resin-based and glass ionomer-based)
- What this could lead to
- If successful, this study could help dentists choose better sealants to prevent cavities in children's newly erupted molars.
- What could go wrong
- This is a small, early-stage trial with only 40 children, so results may not apply to everyone. Sealants may fail or cause minor issues like discoloration.
