Faraoni, Juliana Jendiroba / de Andrade, Julia Barone / de Matos, La ís Lopes Machado / Palma-Dibb, Regina GuenkaPage 701 - 706Purpose: To evaluate the effects of stomach and duodenal fluid on enamel surfaces, simulating the action of refluxed liquid in patients with duodenogastric reflux.Methods and Materials: Forty bovine incisors were used to obtain enamel fragments. Only half of the enamel surface was exposed to erosive challenges; the samples were then randomly divided into the following four groups (n = 10): G1: HCl; G2: HCl + pepsin; G3: HCl + ox bile + NaHCO3; and G4: HCl + pancreatin + NaHCO3. The specimens were placed in 37 °C solutions, six times per day, for 20 s, over a period of 5 days and then analysed for morphology, surface roughness and the step formed on the dental enamel using confocal laser microscopy. The data were analysed using the Kruskal-Wallis and Dunn's test (p
