Cone-Beam CT Evaluation of Root Canal Variations in Permanent Mandibular Premolars

A thorough understanding of the root canal system configurations is essential for increasing the success of root canal treatments and ensuring favorable long-term outcomes. This cross-sectional study aimed to evaluate the differences in root canal morphology of mandibular premolars. A total of 151 mandibular premolars were evaluated using cone-beam computed tomography (CBCT). The pulp canal configurations of both first and second mandibular premolars were analyzed across coronal, axial, and sagi
