PREVALÊNCIA DOS TIPOS DE IMPACÇÃO DE TERCEIROS MOLARES NA CLÍNICA ODONTOLÓGICA DE ENSINO DO CENTRO UNIVERSITÁRIO DE ANÁPOLIS – UNIEVANGÉLICA

Abstract

Third molars represent the largest portion of dental retention and the degree of impaction is directly related to the complexity of tooth extraction. Objective: The present study investigated the prevalence of impaction in third molars related to the bones of the maxillo-mandibular complex at the Clínica Odontológica de Ensino of Centro Universitário de Anápolis – UniEVANGÉLICA. Methods: The analysis was performed according to the Pell and Gregory classifications, which determine the degree of impaction of the dental element and Winter, which evaluate the angulation of the long axis of third molars. This is an observational research conducted through radiographic analysis of stored documents of patients treated during the clinical stages of the 7th and 8th periods and the subject “Advanced Topics in Surgery”, between the years 2015 to 2018. Results: Using a proposed classification by winter, the vertical position prevailed in 81% of cases in maxillary elements and 63% of the mandibular elements. Based on the Pell and Gregory classification, position A had a prevalence of 66% in the mandibular elements and class 1 of approximately 58%. Based on the adaptation made in the study of Pell and Gregory classification, position A prevailed about 58% in the maxillary elements. Conclusions: According to the classification of Pell and Gregory, it was concluded in the data obtained in the study that there was a higher prevalence of position A1 for mandibular teeth and position A for maxillary teeth. According to the Winter method, the vertical pattern was the most prevalent for both jaws.
