Objective: This research aimed to assess the acidity of the liquid diet ingested by the patients of the UNIVALI pedodontics. Materials and method: It is characterized as a descriptive, transversal study, by means of a primary data collection, followed by a laboratory phase. The population comprised 76 responsible for the children attended in the pedodontics of UNIVALI in the first and second semester of 2012, constituting a non-probabilistic sample obtained by convenience. In the first stage, the parents or guardians answered the questionnaire regarding the types of beverages most consumed by children at 5 moments of the day: breakfast, lunch, dinner, snacks and drinks elected for quenching thirst in between meals. The liquids were grouped into: G1- milk and add-ons; G2- industrialized juices, natural or as powder; G3- soft drinks; G4- nothing or water. On the second stage, the pH and titratable acidity were determined in the elected drinks. The data were presented descriptive form. Results: It was demonstrated that all drinks of groups G-2 and G-3 present erosive potential, since they presented pH values under 5.5. The acidic drinks are consumed mostly at lunch (85.52%) and dinner (64.47%) and the milks and derivatives for breakfast (89.47%) and snacks (51.32%). For most people (89.47%), water was chosen for quenching thirst in between meals. Conclusion: It is concluded that all drinks from groups 2 and 3 present erosive potential and could contribute to the development of erosion damages, especially in children who use them as the first choice to quench thirst.
