Estudo radiográfico da prevalência de anomalias dentárias por meio de radiografias panorâmicas em diferentes faixas etárias

Abstract

The dental anomalies result from deviations of the normal process of growth, development and cell differentiation. They occur due to environmental factors, genetic or as manifestations of systemic disorders. The literature shows different prevalence, location, gender predominance and other characteristics. The aim of this study was to determine the frequency of frequency of dental anomalies as the form: fusion, taurodontism and dens in dente, and the further development: supernumerary, agenesis, macrodontia, microdontia and transposition in patients from dental radiology clinic DOC Center in Campo Grande Mato Grosso do Sul, in different age groups. This prospective study was conducted from 2011 to 2013 through the observation of panoramic radiographs archived and were selected radiographs of 3053 patients aged from 8 to 18 years old and the abnormalities were classified using form, development, pacient’s age, gender and location parameters. Patients with syndromes were excluded from the sample. From the 3053 radiographs analyzed, 606 (19.85%) had abnormalities and 60.6% occurred in females and 39.4% in males. The abnormalities more frequent were: Dens in dente: 0.3% Microdontia: 16.0% Supernumerary: 16.5%, Taurodontism: 1.7%, Transpose: 1.0%, Fusion: 0.3%, agenesis: 64.2% and Macrodontia: 0.0%. The results infer that on the sample population the prevalence of tooth abnormalities was 19.85%.
