Fluoride has been used to prevent dental caries for children and community since 1945. In Vietnam, there are over 4 millions children who are using fluoride topically in schools across the nation. Conducting children to rinse their mouth by fluoride water has became one of the interventions of school dental program for over past 20 years. So it is necessary to determine the fluoride absorbability into tooth enamel in order to assess its anti-caries ability indirectly. This study was carried out to assess the ability of fluoride for caries prevention when using topically. Tooth enamels after treated in pH cycling with conditions as in the oral cavity were analyzed to determine the fluoride concentration. The results showed that significant of fluoride was absorbed into tooth enamel. It was al so suggested that fluoride that are provided by the School Dental Program has ability in prevention from dental carries.
