Abstract(s)
Objetivo: Avaliar a anatomia dentária interna e externa dos primeiros molares maxilares segundo a classificação Ahmed com o recurso à utilização da Cone Beam Computed Tomography (CBCT), de pacientes que frequentarão Clínica Dentária Egas Moniz no Instituto Universitário Egas Moniz.
Materiais e Métodos: Foram avaliados 110 CBCTs, onde foram incluídos 218 molares superiores, na Clínica Dentária Universitária Egas Moniz. Todos os dentes foram avaliados em 3 planos: coronal, sagital e axial.
Resultados: Os primeiros molares maxilares que foram incluídos na amostra eram multirradiculares com três raízes e com três e quatro condutos. Encontraram-se 30 codificações diferentes com a classificação de Ahmed, o código mais prevalente foi ³MM MB¹ DB¹ P¹. A prevalência de canais acessórios presente na amostra foi 6,9 %.Não se encontraram diferenças, estatisticamente significativas com o género e a arcada.
Conclusão: A anatomia dentária do primeiro molar maxilar é complexa. Nesse estudo foram encontradas 30 codificações diferentes da classificação de Ahmed. O uso do CBCT é de grande importância na avaliação da anatomia dentária.
Objective: To evaluate the internal and external dental anatomy of maxillary first molars according to the Ahmed classification using Cone Beam Computed Tomography (CBCT) of patients attending the Egas Moniz Dental Clinic at the Egas Moniz University Institute. Materials and Methods: 110 radiographic images, where 218 upper molars were included, were evaluated at the Clínica Dentária Universitária Egas Moniz. All teeth were evaluated in 3 planes: coronal, sagittal and axial. Results: The maxillary first molars that were included in the sample were multirooted with three roots and with three and four canals. Thirty different codings were found with the Ahmed classification, the most prevalent code was ³MM MB¹ DB¹ P¹. The prevalence of accessory canals present in the sample was 6.9%. No statistically significant differences were found with gender and arch. Conclusion: The dental anatomy of the maxillary first molar is complex. In this study, 30 different codings of Ahmed's classification were found. The use of CBCT is of great importance in the evaluation of dental anatomy.
