ABSTRACT

Na presente pesquisa foram utilizados 103 primeiros molares inferiores obtidos no Banco de Dentes do Curso de Odontologia da UFPE com o objetivo de avaliar, através de radiografias periapicais e da diafanização, a morfologia interna das raizes mesial e distal e classificá-las de acordo com Vertucci (1984). Na raiz mesial foram identificados dois canais em 96,12% dos casos, curvos para a distal em 79,91%, tipo II em 60,20%. A raiz distal apresentou canal único em 91,26% dos casos, reto em 73,15%, tipo I em 69,90%. A técnica radiográfica e a diafanização mostraram-se bastante efetivas para o estudo e visualização da morfologia interna do sistema de canais radiculares.


In this research were selected hundred three human mandibular molars, obtained from Banco de Dentes do Curso de Odontologia da UFPE, the root canal morphology were evaluated by X-rays examination and of the transparent teeth of the mesial and distal of the first mandibular molar root, and classifying them according to Vertucci (1984). Two channels into the mesial root were detected at 96,12%, curved for the distal at 79,91%, type II of the Vertucci at 60,20%. The distal root presented a single root channel at 91,26%, straight at 73,15% and the Vertucci's type I at 69,90%. The radiographic technique and the transparent teeth were effective for the study and observation of the internal morphology of root canals system.
