Summary
This study tests whether a gel containing silver diamine fluoride can stop cavities in preschool children as effectively as the standard liquid version. About 630 healthy children with at least one cavity will receive the gel or solution every six months for 30 months. The goal is to see if the gel hardens the cavities and prevents them from getting worse.
