CBCT Assisted Endodontic Management of Teeth for Aberrant Roots: Case Series

Abstract

Cone Beam Computed Tomography (CBCT) is a radiographic imaging technique which provides accurate, high-quality, threeDimensional (3D) images of various parts of head and neck. They deliver images with a spatial resolution of teeth required for diagnosis, treatment planning and postoperative evaluation. The aim of this case series is to describe the importance of determining the root canal morphology with the help of CBCT. This case series presents the endodontic management of a three rooted maxillary first premolar, maxillary first molar with single palatal root and three canals and mandibular first molar with five canals using CBCT. The axial images from CBCT show Gulabivwala K Type I (3-1) canal pattern in distal root of mandibular first molar (36) and palatal root of maxillary first molar (26) according to Al-Quadah Awawdeh showed Type XXII (3-2-1) canal configuration. Biomechanical preparations of all the teeth were done with hand as well as rotary file systems and lateral compaction obturation technique was used. With the advancing technology in imaging, there are possibilities to detect and treat a number of variations particularly in posterior teeth leading to successful endodontic treatment.
