Even though many studies on fluoride varnishes have been conducted, the comparisons and evaluations among various fluoride varnishes of the market are still insufficient. Thus, this study compared and evaluated the effect of fluoride varnish products of the market. Study subjects were the following 6 products: FluoroDose®, EnamelastTM , ClinproTM white varnish, CavityShieldTM, V varnishTM, MI varnishTM. We measured the amount of fluoride ion release eight times during the 168 hours of total experiment time to see the variations by the lapse of the time period using bovine teeth, and the remineralization rate with Quantitiative Light-induced Fluorescence. V varnishTM group and MI varnishTM group showed high remineralization rates with statistically significance while CavityShieldTM group was the lowest rate of remineralization. (p <0.05). Scanning electron microscope was used to compare remineralization effect of varnishes. Demineralized enamel was observed as the number of enamel crystal was very small; enamel rods and crystals were highly protruding. Remineralized groups with fluoride varnishes show the decreasing tendency of the surface roughness compared to the demineralized enamel.
