The morphology of the root canal system is highly variable and complex. Therefore, comprehensive knowledge of its anatomy and the planning of the procedure using imaging systems, such as 3D cone beam computed tomography (CBCT), prior to performing endodontic treatment, improve the prognosis, increasing the chances of success. The aim of this report is to show the sequence of a clinical outcome of a lower first premolar (tooth 4.4) with a complex anatomy, using CBTC in diagnosis and planning. Diagnosis, treatment planning and root canal of a lower first premolar with two canals using 3D computed tomography: Case Report. RESUMEN. El tratamiento endodóntico debe considerar que los dientes presentan una morfología del sistema de canales radiculares con alta variabilidad y complejidad. Por lo tanto, el conocimiento acabado de la anatomía radicular y la planificación del procedimiento utilizando sistemas imagenológicos previos a la realización del tratamiento endodóntico, como la tomografía computarizada 3D (CBTC), mejoran el pronóstico, aumentando las probabilidades de éxito. El objetivo de este reporte es mostrar la secuencia de una resolución clínica de un primer premolar inferior (diente 4.4) con una anatomía compleja, utilizando el CBTC tanto en el diagnóstico como en la planificación.
