Objetivo: Caracterizar a anatomia dentária interna e externa dos primeiros molares mandibulares segundo a classificação de Ahmed.
Materiais e Métodos: A amostra consistiu em 183 Tomografias Computorizadas de Feixe Cónico (CBCTs), num total de 288 primeiros molares mandibulares realizados na Clínica Dentária Egas Moniz no período compreendido entre 1 de Janeiro de 2020 a 31 de Janeiro de 2022. As imagens radiográficas foram analisadas através do software Sidexis 4.
Resultados: Os 288 primeiros molares mandibulares analisados segundo a classificação de Ahmed, apresentaram um total 53 configurações diferentes, com maior prevalência no código 2MM M2-1 D1 (25,0%) segundo a classificação de Ahmed.
Todos os dentes incluídos na amostra continham 2 raízes (100%), predominantemente com 2 canais na raiz mesial e 1 canal na raiz distal (70,5%). Foram encontrados 27 dentes com canais acessórios (9,4%), 25 com duplo ápex (8,7%) e 1 com raiz bífida (0,3%). A existência de dois canais na raiz mesial e um canal na raiz distal foi superior no género feminino, na faixa etária entre os 11 e os 32 anos (p=0,043). Em relação ao
ápex duplo, este foi superior na faixa etária entre os 11 e os 32 anos (p=0,046).
Conclusão: A anatomia dentária dos primeiros molares mandibulares revelou ser muito diversificada, com predomínio no código 2MM M2-1 D1 segundo a classificação de Ahmed. Todos os dentes analisados apresentavam duas raízes e, maioritariamente, dois canais na raiz mesial e um canal na raiz distal.
Objective: To characterize the internal and external dental anatomy of the mandibular first molars according to Ahmed’s classification. Materials and Methods: The sample consisted of 183 Cone Beam Computed Tomography (CBCTs) in a total of 288 mandibular first molars performed at the Egas Moniz Dental Clinic since 1st January from 2020 to 31st of January from 2022. The radiographic images were analyzed using the Sidexis 4 software. Results: The 288 mandibular first molars analyzed according to Ahmed’s classification, presented a total of 53 different configuration, with a higher prevalence in the code 2MM M2-1 D1 (25,0%) code according to Ahmed’s classification. All teeth included in the samples contained 2 roots (100%), predominantly with 2 canals in the mesial root and 1 canal in the distal (70,5%). There were found 27 teeth with accessory canals (9,4%), 25 with double apex (8,7%) and 1 with bifid root (0,3%). The existence of two canals in the mesial root and one canal in the distal root was higher in females aged between 11 and 32 years (p=0,043). In relation to the double apex, it was higher in the aged between 11 and 32 years (p=0,046). Conclusion: The dental anatomy of the mandibular first molars have proven to be very diverse, with a predominance of the code 2MM M2-1 D1 according to Ahmed’s classification. All teeth analyzed had two roots and mostly two canals in the mesial root and one canal in the distal root.
