ENDODONTIC TREATMENT OF MANDIBULAR PREMOLAR WITH THREE CANALS USING CBCT

Abstract

Background Mandibular premolars generally have single root and single root canal. The frequency of mandibular premolars with two roots and three canals is extremely rare. Objective To present the management of a mandibular second premolar with two roots and three canals which was identified by cone-beam computed tomography (CBCT) Case Description 13 years old male patient having pain in the right mandibular second premolar was referred for the endodontic treatment. The preoperative periapical radiograph showed the presence of two roots. After identification of three canals by CBCT two in the distal root and one in the mesial root, the endodontic treatment was performed. Radiographic follow-up of the case revealed no signs of periapical inflamation after one year. Conclusion Dental anatomical variations are important and must be identified preoperatively for a successful treatment outcome in endodontics. CBCT can be used for the preoperative diagnosis of complex root canal anatomy
