Sezai / Kargul, BetulPage 311 - 318Purpose: The aim of this study was to investigate the in vitro effect of casein phosphopeptide –amorphous calcium phosphate (CPP-ACP) and fluoride-containing varnish on prevention enamel erosive tooth wear.Materials and Methods: A total of 28 enamel samples were prepared from human molars, divided into four groups: CPP-ACPF varnish, TCP-F varnish, NaF varnish, and deionised water. For the remineralisation process stimulated human pooled saliva was used. After treatment, all enamel samples were exposed to 10 ml of Coca Cola. Ca++ release was determined by atomic absorption spectroscopy (AAS). The surface topography was evaluated by atomic force microscopy (AFM). Surface microhardness of enamel was analysed and SMHR % (surface microhardness reduction ) was calculated. Data were analysed with repeated measures analysis of variance (ANOVA).Results: Deionised water demonstrated a statistically significantly higher Ca+2 release compared to those of groups NaF> fTCP> CPP-ACPF, respectively (p
