Abstract:

BACKGROUND: Demineralization of dental enamel is a complication in common after orthdontics treatment. The application of fluoride can inhibit the occurrence of demineralization of dental enamel and promote enamal remineralization.
OBJECTIVE: To explore the mechanism and the application of fluoride in enamel adhesive in preventing enamel demineralization and reducing incidence of the enamel blazes after the treatment.
METHODS: PubMed database from January 1990 to August 2010 was retrieved by computer with the key words of “fluoride release; enamel demineralization; enamel adhesive; orthdontics treatment” in English. CNKI database from January 1990 to August 2010 was retrieved with the key words of “fluoride release; enamel demineralization; enamel adhesive; orthdontics treatment” in Chinese. Literatures were limited to English and Chinese. Literatures concerning the development and clinical application of fluoride in enamel adhesive were included.
RESULTS AND CONCLUSION: Hydroxy of Hhydroxyapatite unit cell was displaced by fluorine, the crystallinity, stability and hardness of apatite unit cell were enhanced. Fluorinion, calcium and phosphate ions in saliva constitute a mineralization system to improve the effect of enamal remineralization. The development of resin adhesive with slow-release fluorine source is an important direction to prevent demineralization of dental enamel. The effect of fluorine releasing in resin adhesive with inorganic and organic slow-release fluorine has been verified, and its clinical effect is need to be further studied.
