Abstract

|
|
Subjects of this study were : FluoroDose? (FD, Centrix Inc., USA), EnamelastTM (EL, Ultradent Product Inc., USA), ClinproTM white varnish (CW, 3M ESPE, USA), CavityShieldTM (CS, 3M ESPE, USA), V varnishTM (VV, Vericom, Korea), MI varnishTM (MI, GC, Japan). The amount of fluoride ion release was measured eight times during 168 hours to see change in accumulation with the course of time using a measuring instrument. And the remineralization rate was measured with Quantitative Light-induced Fluorescence (QLF). 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). After that, several chosen samples were scanned through electron microscope (SEM). 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.
