ABSTRACT

La incidencia de dos conductos en la raíz distovestibular en un primer molar maxilar es una variación anatómica poco frecuente del sistema de conductos. Los investigadores han demostrado múltiples forámenes, conductos adicionales, furcaciones, deltas, conexiones entre conductos, conductos en forma de C y conductos accesorios. Este reporte de caso clínico presenta el tratamiento de un primer molar maxilar con dos conductos en la raíz ovestibular. Se muestra clínicamente la presencia dedos conductos distovestibulares tipo 2-1, los cuales se instrumentaron manualmente con técnica corono- apical con limas K-Flexofi le de 25 mm y se obturaron con la técnica de condensación lateral, con conos de gutapercha, conos accesorios número FF, F y cemento Sealapex. Después del tratamiento se selló el diente con cemento temporal y se refirió para realizar la restauración defi nitiva...


The presence of two canals in the distobuccal root of a maxillary fi rst molar is a rare anatomical variation of the canal systems. Investigators have shown multiple foramina, additional canals, furcations, deltas, intercanal connections, C-shaped canals, and accessory canals. This clinical case reports the clinical treatment of a maxillary fi rst molar with two canals in the distobuccal root. We present a clinical case involving the presence of the two 2-1-type distobuccal canals. Manual instrumentation was performed using the crown-down technique with the aid of 25 mm K-fl exofi le fi les. The canals were fi lled using the lateral condensation technique and gutta-percha cones, FF and F accessory cones, and Sealapex cement. Following the treatment, the tooth was sealed with temporary cement and the patient was referred for fi nal restoration. The aim of this paper is to examine the anatomical variations that can occur in the root canal system and the technologies that can be used to correctly identify the location of additional canals.
