Maxillary and mandibular first molar with five root canals diagnosed with cone-beam computed tomography: A review and two case reports

Abstract

Thorough knowledge of root canal morphology is essential for the success of endodontic treatment. There are rare aberrant, variations in canal number and configuration in maxillary and mandibular molars, which could affect treatment outcome. This paper presents the endodontic management of a maxillary first molar with two palatal canals and three buccal canals and mandibular first molar with two mesial and three distal canals. In this paper this morphology was confirmed using cone-beam computed tomography (CBCT) and surgical operating microscope . CBCT can provide dentists with high quality 3-dimensionals images of dental structure due to it's high spatial resolution. This paper is intended to reinforce clinician's awareness of the rare morphology of root canals
