title: Relationship between dental caries experience and surface enamel fluoride concentration in young men from three optimally fluoridated cities.
abstract: An in vivo enamel biopsy technique was used to determine relationships between dental caries experience and surface enamel fluoride levels in a group of young men from three fluoridated cities on the east coat of the U.S. A significant inverse relationship between enamel thickness and fluoride concentration was observed, and a weak but statistically significant inverse relationship between caries scores and enamel fluoride concentration was noted. The effect was most pronounced in biopsies which did not exceed 5.9 micron in depth.
