Fluorine uptake in bovine enamel from various treatment agents.

• Bovine tooth enamel with a low and uniform fluorine content was used for the study of fluorine uptake by the Micro-Acid-Drop enamel biopsy technique from different treatment agents commonly used in Sweden. The fluorine concentration in the enamel was also measured after an exposure of the treated test surfaces in artificial saliva for 90 minutes. Sodium fluoride 0.2% and 2%, ferric aluminum fluoride solution and Duraphat varnish showed a high uptake of fluorine in the enamel with the highest concentration in the surface layer. Fluor Protector and the toothpastes showed a considerably lower fluorine uptake. After immersion in artificial saliva of the specimens, the concentration of fluorine in the enamel decreased.
