ABSTRACT
The present study is aimed at evaluating the anatomic concurrence between foramen openings and root apexes of 247 upper and lower permanent human molar canals, the distance between these structures, the instrument that best fits into the root canal, as well as the direction of foramen deviation. Sixty-four of the canals were partially impenetrable and were discarded. The findings showed that 39.9% ofthe root canals studied had their apical foramen concurrent with their root apexes and 60.1% did not. Clinicians must be made aware of this important anatomical detail, which could be indispensable for successful endodontic treatment.
RESUMO
O objetivo da presente pesquisa foi avaliar a coincidência anatômica entre as aberturas foraminais e os ápices radiculares de 247 canais de molares humanos permanentes superiores e inferiores, a distância entre essas estruturas, a direção para a qual ocorreu o desvio do forame, bem como a lima que melhor se ajustou ao canal. Sessenta e quatro canais encontravam-se parcialmente impenetráveis, sendo descartados do estudo. Os resultados demonstraram que 39,9% dos canais radiculares estudados tiveram seus forames apicais coincidentes com os ápices radiculares, e 60,1% não. Os dados encontrados alertam para esse importante detalhe anatômico, que pode ser fundamental para o sucesso do tratamento endodôntico.
