Abstract
DMFS examinations and fluoride biopsies of enamel were carried out on 387, 6- to 9-year-old schoolchildren, receiving fluoridated or pure citrus beverage for 36 months. A group not receiving beverage in school served as the control. A reduction of about 30% in the incremental caries rate was observed in the children receiving fluoridated beverage. No significant differences were observed between the mean F concentrations in the enamel biopsies for all groups.
