Objective: The aim of this study was to verify the in vitro erosive potential of beverages frequently consumed by Brazilian children, including cola based soft drinks, regular and zero, industrialized box and powdered juices, chocolate milk drink and tap water. Methods: 42 sound primary bovine teeth were prepared and flat surfaces of enamel were obtained and distributed into six groups. The pH of each beverage was measured. The specimens were submitted to erosive challenge with the tested products for 28 consecutive days. The surface roughness was evaluated before and after erosion-remineralization cycling in profilometer. Data were analyzed by the paired T test (groups with normal distribution) and the Wilcoxon test (groups with non-normal distribution). The 5% level of significance was adopted for all analyzes. Results: In general, the surface roughness values of the primary bovine dental enamel increased from the initial values. For the groups water (p = 0.134), chocolate (p = 0.283) and juices (p = 0.091), the roughness did not present a significant intragroup difference before and after erosive challenge. Both, regular cola soft drink (p = 0.043) and sugar zero cola soft drink (p = 0.049) showed significant erosive effect on deciduous bovine teeth. Conclusions: Regular cola soft drink and sugar zero cola soft drink significantly influence the roughness of deciduous bovine dental enamel, demonstrating a greater erosive potential among the beverages most consumed by Brazilian children.
