Aim: The purpose of this study was to evaluate, in vitro, the effect of a single application of a casein phosphopeptide-amorphous calcium phosphate paste (CPP-ACP) in comparison with a fluoride varnish, in enamel of bovine teeth, after erosive challenge using cola soft drink. Materials and Methods: Forty-five enamel specimens were obtained from bovine teeth, selected according to the surface hardness and randomly divided into three groups: G1 - Fluoride varnish, G2 - CPP-ACP-based paste, and G3 - Control, without any treatment. The enamel specimens were treated using each group material and subjected to three daily erosive challenges by immersion of the specimens in cola soft drink for 5 min, during 5 days. Between the erosive cycles, the enamel specimens were immersed in artificial saliva. The initial profilometry (prechallenge) and the final profilometry (postchallenge) were used to evaluate the enamel loss. Statistical Analysis: Data were analyzed using ANOVA and Tukey's Test (P < 0.05). Results: The single application of CPP-ACP (G2: 4.17 ± 0.77 μm) resulted in less enamel loss compared to control (G3: 4.74 ± 0.52 μm) and higher enamel loss compared to fluoride varnish application (G1: 3.01 ± 0.45 μm) (P < 0.05). Conclusion: The CPP-ACP paste was effective in reducing enamel wear after erosive cycles, however, the best potential for erosion prevention was observed when using the fluoride varnish.
