Odontogenesis is a complex process that involves a reciprocal interaction between the dental lamina and ectomesenchyma originating from neural crest cells. Failures can occur during this process, causing dental anomalies. We aimed to evaluate, in children and adolescents, the prevalence of dental anomalies. We conducted a clinical-radiographical descriptive, cross-sectional, retrospective study of young patients to evaluate the prevalence of dental anomalies resulting from failures in odontogenesis. Three hundred and four (304) records were analyzed, with 75 anomalies found, distributed among 66 patients. Between the patients with these anomalies 41 (62%) were female and 25 (38%) were male. The most frequent dental anomalies were: agenesis (7.6%), enamel hypoplasia (4.6%), giroversion (4.6%), imperfect amelogenesis (1.6%), supernumerary tooth (1.6%) and root dilacerations (1.6%). According to the affected arch we found the following results: mandible (45.3%), maxilla (32%), maxilla and mandible (22.7%). According to the side affected by anomalies, the data were as follows: left (28.7%), right (24.3%), left and right (46.9%). It was observed a high prevalence of dental anomalies in the studied population, emphasizing the importance of epidemiologic research to recognize the occurrence and characteristics of those lesions in young patients in order to improve Dental Surgeon`s knowledge, since they need to be able to diagnose and treat it.
