Radiografia panorâmica no contexto da segurança pública: estimativa da idade no caso de Belém/PA

Abstract

This dissertation aims to estimate the chronological age from the mineralization of third molar teeth in a population from 15 to 21 years, residents in the city of Belém, State of Pará, through panoramic radiographs, based on the study of the stages of development of these teeth, sorting according to the table of chronology proposed by dental mineralization Nicodemo et al. (1974). To this end, we used the statistics descriptive technique analysis, variance analysis and Tukey test, correspondence analysis and discriminant analysis applied to variables of third molars mineralization stage, gender, age and tooth. From the applied analysis this research could classify the sample into groups of less than 18 years and over 18 years of age. In this context, and based on research in specialized literature we concluded that the average age of the initial stages of mineralization occurred far above the average proposed by Nicodemo et al. (1974), only matching from the stage 7 of mineralization. There was no significant statistical difference for the development of third molars between sexes.
