Introduction: dental erosion is the irreversible loss of the hard dental tissues caused by acids and/or chemical chelation without bacterial involvement. Demineralization of the dental tissues in dental erosion originates from the action of extrinsic or intrinsic acids that mainly involves the consumption of acid beverages, medicines, and gastroesophageal problems. Presently, the combination of these factors has been attributed to the increase of dental erosion prevalence. Objective: the present paper aimed, through a literature review, at analyzing studies about the prevalence of dental erosion carried out in Brazil and identifying the factors associated with the erosive wearing. Method: the literature search was conducted based on Medline data, using as the subject descriptors the terms: tooth erosion, prevalence, Brazil. As national indexer, the Brazilian Bibliography of Dentistry (Bibliografia Brasileira de Odontologia - BBO) was investigated, using for the search the key words: dental erosion and prevalence. Scientific articles for prevalence studies in children and adolescents were included. These were analyzed and data were collected on: authorship, year of publication, sample size, age, city, local of the collection, gender, teeth examined, prevalence, severity, identification of etiological factors, and association with socioeconomic factors. Results: these data were presented and discussed. Conclusion: it was concluded that the prevalence of erosion was quite varied, being higher in deciduous teeth, mostly affecting just the enamel. The gender and socioeconomic status had little influence on the determination of the prevalence of this alteration. The erosive wearing was mainly associated with the consumption of food, beverages, candies, acidic drugs, and gastroesophageal reflux. [ABSTRACT FROM AUTHOR]
