Abstract:

Caries and erosion are examples of demineralized enamel. Fluoride often used to reduce demineralization effect. The purpose of this study was to obtain information about effects of fluoride on enamel microhardness demineralization. The method used was an in vitro study on specimens of premolars and canines which was caries free and fractures free. The teeth were cut at CEJ and planted on resin. 24 sample were divided into two groups: A control and test group. Samples were immersed in acidic solution with pH 5.0 for 6 hours to demineralization. Then were stored in artificial saliva with pH 7.0 for 17 hours to remineralization. In test group, fluoride applied for 4 minutes, then stored in artificial saliva for 30 minutes. Remineralization and fluoride applications made for 7 days. Demineralization and remineralization assessed by enamel microhardness. The research showed enamel microhardness after remineralization recover for 80% in objects group and 48.7% in control group. Conclusions of this study was that microhardness of demineralize enamel improved better after fluoride aplication.
