ABSTRACT
The aim of this study was to investigate and classify the internal morphology of the mesiobuccal root of upper first permanent molar, using the cone beam computed tomography. A total of 60 first permanent molars, not healthy and with intact pulp cavity, belonging to the Postgraduate dentistry bank, underwent the computed tomography. Axial images of each tooth were analyzed, and results showed that according to the number of conduits, 21 specimens (35 percent) had single conduit and 39 exhibited two conduits (65 percent). In reference to the types of internal configuration most commonly found according to Vertucci classification; type I (single channel that extends from the pulp chamber to the apex) was the most frequent (35 percent), followed by type II (two separate canals leaving the pulp chamber and joining next to the apex forming a single channel) with 30 percent. It was found that the morphology of the variation of mesiobuccal root, of upper first permanent molar is relatively high, and computed tomography proved to be an effective method for diagnosis.
RESUMEN
El objetivo de este estudio fue investigar y clasificar la morfología interna de la raíz mesiovestibular del primer molar permanente superior, utilizando la tomografía computarizada cone beam. Fueron utilizados 60 primeros molares permanentes superiores, pertenecientes al Banco de Dientes del Posgrado en Odontología, con cavidad pulpar intacta, los cuales fueron sometidos a TC. Se analizaron las imágenes axiales de cada diente y se obtuvieron los siguientes

resultados:

21 muestras (35 por ciento) tenían un solo canal y 39 muestras (65 por ciento) dos canales; los tipos de configuración interna más comunes de acuerdo a la clasificación Vertucci fueron Tipo I, 35 por ciento, un solo canal que se extiende desde la cámara pulpar hasta el ápice radicular y Tipo II, 30 por ciento dos canales separados que salen de la cámara pulpar y se unen cerca del ápice radicular formando un solo canal. La morfología de la raíz mesiovestibular del primer molar superior era relativamente alta. La tomografía computarizada demostró ser un método eficaz para el diagnóstico.
