Effect of sodium lauryl sulfate on the uptake of fluoride from NaF and MFP by etched enamel in vitro.

Melsen and Rolla (1983) have previously shown that sodium lauryl sulfate may reduce the cariostatic effect of fluoride when present together with sodium monofluorophosphate during topical application. The aim of the present study was to examine the in vitro deposition of fluoride on etched enamel during topical application with sodium fluoride in combination with sodium lauryl sulfate. In addition, uptake by etched enamel of fluoride sodium monofluorophosphate in combination with sodium lauryl sulfate was examined. It was found that sodium lauryl sulfate decreased the amount of fluoride taken up by the enamel.
