ABSTRACT
The aim of this study was to review the fluoride release and recharge abilities of fluoride-releasing dental restoratives, and discuss the current status concerning the prevention or inhibition of secondary caries. Fluoride-containing dental materials show clear differences in the fluoride release and uptake characteristics. The elution of fluoride is a complex process. It can be affected by several intrinsic variables, such as resin matrix and filler composition. It is also influenced by experimental factors, i.e., storage media, frequency or change of the storage solution, composition and pH value of saliva, dental plaque and pellicle formation. Due to the fact that fluoride levels leached from fluoride containing filling materials decreased over time the "recharging" of restoratives with fluoride has been suggested to maintain a continuously increased level of fluoride release. The ability of a restorative material to act as a fluoride reservoir is mainly dependent on the type and permeability of filling material, on the frequency of fluoride exposure and on the kind and concentration of the fluoridating agent. In vitro, several fluoride-releasing restorative materials have shown to inhibit enamel and dentin demineralization produced by acidic gels or demineralizing buffer solutions. Thereby, inhibition of enamel demineralization is located up to a distance of 7 mm from the edge of the material. Despite the cariostatic effect achieved from an increase of fluoride content in saliva, plaque, and dental hard tissues, clinical studies exhibited conflicting data as to whether or not these materials sufficiently prevent or inhibit secondary caries compared to non-fluoridated restoratives.
