NCT ID NCT07382245
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tests two cavity-stopping liquids in 60 children aged 3-5 with active tooth decay. One is a well-known treatment that turns cavities black; the other is a newer version that may avoid staining. Researchers will check which works better over 12 months, and ask parents about pain and satisfaction.
