Fluoride-releasing dental restorative materials may provide an additional benefit in preventive dentistry. Although not currently available in the United States, a fluoride-releasing amalgam has demonstrated recurrent caries inhibition at enamel and dentin restoration margins. Likewise, both chemical-cured and light-cured glass ionomer cements have demonstrated caries inhibition at enamel and dentin restoration margins. Fluoride-releasing resin composites have also consistently demonstrated recurrent caries inhibition at enamel margins, yet there are conflicting results whether caries inhibition occurs at dentin margins. Preliminary studies indicate that glass ionomer cement and fluoride-releasing resin composite have synergistic effects with fluoride rinses and fluoridated dentifrices, in the remineralization of incipient enamel caries. The materials may act as a fluoride delivery system. Upon exposure to additional external fluoride, the material surface undergoes an increase in fluoride. This fluoride is subsequently released and has demonstrated demineralization inhibition and even remineralization at adjacent tooth structure. Clinical research to evaluate these fluoride-releasing restorative materials may provide further information for clinical recommendations.
