NCT ID NCT07181967
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tests whether a silver liquid (silver diamine fluoride) is better than standard fluoride varnish at reducing cavity-causing bacteria in children aged 3 to 8. Each child will get both treatments on different sides of their mouth. The goal is to see which one works better over three months.
