AB - Anatomical variations of the root canal system of mandibular molars are common and often present challenges for endodontic treatment. In some cases, an additional root is located in the distolingual, radix entomolaris (RE), or more rarely in the buccal, radix paramolaris (RP). This case report illustrates rare nonsurgical retreatment of the complex root canal morphology of a RP and demonstrates the utility of cone-beam computed tomography (CBCT) and 3D printing in managing such a case. Underscored is the need for clinicians to understand the possible variations of root canal morphology of mandibular molars and the role CBCT imaging can play in addition to periapical radiographs in order to successfully treat a tooth with radix paramolaris.
