Prevention of Early Childhood Caries Using Fluoride Varnish
Resources

Principal Investigator: Jane A. Weintraub, DDS, MPH

Project Director: Francisco Ramos-Gomez, MS, DDS, MPH

Brief summary:
The purpose of this study is to test the efficacy of fluoride varnish
brushed onto the teeth to prevent tooth decay in young children. Children, initially 6-44 months old who do not have tooth decay are randomly assigned to one of three groups: one group gets fluoride varnish once/year; one group gets fluoride varnish twice/year; and the third group does not get any fluoride varnish. Parents or caregivers of all children receive counseling about oral health and all participating children receive a dental screening annually for two years (three screenings.)
