Resumo: O conhecimento da morfologia radicular interna tem sido um assunto complexo e extremamente importante, considerando o planejamento e execução da terapia endodôntica. As inúmeras variações anatômicas que existem no sistema de canais radiculares contribuem para as falhas de tratamentos. O propósito desta pesquisa foi investigar em raízes mésio-vestibulares dos primeiros molares superiores o número de foraminas apicais e o diâmetro médio da foramina maior. Foram analisados 78 primeiros molares superiores humanos permanentes extraídos, tingidos com azul de metileno na porção apical. Após o preparo das amostras, os dentes foram submetidos à análise apical em um microscópio clínico operatório com magnificação de 40X. Os resultados obtidos em relação ao número de foraminas observadas foram: ausência de foraminas 2,6%, uma foramina 26,9%, duas foraminas 34,6%, três foraminas 21,8%, quatro foraminas 11,5% e cinco foraminas 2,6%, sendo que o diâmetro médio da foramina maior foi de 0,34 mm. A incidência de três ou mais foraminas e o diâmetro médio da foramina maior alerta para a complexidade anatômica e a necessidade de se encontrar meios adequados para a limpeza do sistema de canais radiculares.

Abstract: Knowledge of dental root internal morphology has been a complex and an extremely important issue regarding the planning and execution of endodontic therapy. The several anatomic variations that might exist in the root canal system have contributed to endodontic treatment failures. The aim of this study was investigate in the mesiobuccal roots of maxillary permanent first molars the number of foramina. The apical anatomy of 78 extracted maxillary permanent first molars was evaluated, the teeth were cleaned of any attached soft tissues or calculus and placed for 1 hour in an ultrasonic bath with 3% hydrogen peroxide, stored in 70% alcohol and the roots were dyed with methylene blue, washed under running water, and dried with pressurized air before the examinations. After the tooth preparation the root morphology of the apical area was examined at 40X magnification. The results of the number of foramina observed in the mesiobuccal roots of maxillary permanent first molars were: not found foramina 2.6%, one foramina 26.9%, two foramina 34.6%, three foramina 21.8%, four foramina 11.5% and five foramina 2.6%. The incidence of three or more foramina alerts to the anatomical complexity and the necessity of finding adequate facilities for cleaning the root canal system.
