The amount of alkali-soluble and alkali-insoluble fluoride was determined in human enamel after one- and six-hour treatments with Duraphat®. The application was carried out on: (1) slightly demineralized enamel covered with artificial plague. (2) cleaned, slightly demineralized enamel, and (3) sound enamel without pre-treatment. After a single Duraphat® treatment lasting six hours, fluoride uptake was higher than after Duraphat® treatment for just one hour in all experimental groups. More fluoride was acquired in both slightly demineralized, plaque-covered and slightly demineralized, cleaned enamel than in sound enamel. Plaque significantly hampered the formation of alkali-soluble fluoride precipitation on demineralized enamel, but its influence on the amount of fluoride taken up by the enamel was minor.
