Popis: Introduction: Dental erosion is defined as an irreversible loss of hard tissue caused by intrinsic and extrinsic acidic sources, non-bacterial dissolution not directly associated with traumatic factors or tooth decay. Aim: The aim of this study was to analyse the ex-vivo pH, titratable acidity and erosive potential of following juices: Theobroma grandiflorum, Annona muricata, Spondias mombin and Spondias tuberosa, which are commonly found and widely used fruits by the population of the northern and north-eastern regions of Brazil. Materials and Methods: Fifteen human third molars, extracted for clinical reasons and obtained from Human Teeth Bank of the Dental School (Federal University of Juiz de Fora), were selected to be immersed in the juices and in 1% citric acid (positive control group) and perform erosive cycles. The samples were immersed in the solutions for 2 minute, five times a day, at intervals of two hour, for four days. Between the erosive cycles, the specimens remained in artificial saliva. Before the beginning of the erosive cycles and at the end of the cycle sequence, specimens were analysed for roughness and for micro-hardness. Statistical analyses were performed using the IBM SPSS Statistics 22.0 software. The results were expressed as a mean±standard error of the mean, and analysed using variance analysis (ANOVA), followed by post-hoc Tukey’s test. The significance accepted was p
