Abstract
Clinical application of topical fluoride agents has proven to be an effective means of reducing the incidence and progression of dental caries. The caries-preventive potential of topical fluorides may be due to 1) the presence of fluoride-rich surface coatings, 2) incorporation of fluoride into hypomineralized enamel, 3) remineralization of the surface layer overlying enamel caries and 4) the bactericidal effect of fluoride. Acid-etching of enamel has been performed routinely to bond adhesive resin materials to sound enamel as a caries-preventive measure. Acid-etching of sound enamel results in 1) a loss of surface enamel (10 to 15μm), 2) exposure of enamel which is more reactive and 3) a tremendous increase in surface area.
