Abstract:
The application of topical fluoride after acid-etching substantially reduces the risk of enamel opacities and caries, but fluoride treatment can reduce strength of the enamel-adhesive interface to a measurable extent. In this in vitro study there was a slight reduction (statistically inconsequential) in bond strength with the use of 2.0% aqueous NaF. In contrast, two acidulated solutions tested here both showed marked reductions (ca. 25%) in bond strengths.
