Anatomía interna del incisivo central inferior mediante proceso de diafanización

Abstract

Objective. To establish the internal anatomy of the lower central incisor in pieces extracted inside the Pucará canton, through the process of diaphanization. Materials and methods. Sixty lower central incisors obtained in the Pucará canton were examined, which fulfilled the inclusion and exclusion criteria of the present study. They were subjected to the process of diaphanization based on the protocol cited by Robertson and through placing Chinese ink was able to observe its internal root anatomy. Results. The 60 pieces obtained were examined, the presence of a second conduit existed in a 23.3%, also the difference existed according to the type of conduit according to the classification of Vertucci, 76.6% had type I configuration, 21.7% type III configuration and 1.7% type V configuration type V. Conclusions. The majority of dental pieces examined in this study correspond to a type I configuration, the second common anatomy is a type III configuration and the third is a type V configuration. The dental diaphanization technique allows us to observe the anatomy of root canals in a three-dimensional conserving the original shape of the roots. The lower central incisor can present great variety in its duct system, which should be considered by the professional.
