Objectives: The aim of this study was to investigate the prevalence of dental anomalies  in children of Cuiabá and then to compare it with the prevalence of these anomalies in the general population. Study design: It was a retrospective study of 324 digital panoramic radiographs of patients who presented to a Radiology Center in Cuiabá, between 2010 and 2011. The followings were recorded for each subject  age, sex and presence of  dental anomalies in maxilla or mandible. Were observed  dental anomalies involving the number, shape of teeth. Results: Dental anomalies were found in 97,2% of children. The distribution of dental anomalies were more frequent in girls than in boys, and the maxilla more than mandible. Impacted tooth (36,6%), followed by hipodontia/agenesis (30,5%) and Rotation/lateralization (15%) were the more frequent dental anomalies in the study population. Conclusion: Early diagnosis of dental anomalies at an early age has great importance because it allows for more comprehensive long-term treatment planning, more favorable prognosis, and, in certain instances, less extensive interception.
