Fluorine depth profiles have been measured into enamel of human teeth by using the nuclear reaction19F(p, α0)16O for incoming proton beam at 1350 keV. Details of fluorine distribution over a few micrometres have been obtained by comparison of the energy spectrum of alpha-particles from the reaction in teeth with that of the standard target of CrF3. The average concentration of fluorine is 1.5 mg/g in the enamel of healthy tooth, while the concentration is below 0.3 mg/g (MDL) in the caried zones. These values can reach 13 mg/g in the enamel of a fluorine tooth.

Abstract
Fluorine depth profiles have been measured into enamel of human teeth by using the nuclear reaction19F(p, α0)16O for incoming proton beam at 1350 keV. Details of fluorine distribution over a few micrometres have been obtained by comparison of the energy spectrum of alpha-particles from the reaction in teeth with that of the standard target of CrF3. The average concentration of fluorine is 1.5 mg/g in the enamel of healthy tooth, while the concentration is below 0.3 mg/g (MDL) in the caried zones. These values can reach 13 mg/g in the enamel of a fluorine tooth.File in questo prodotto:
