This case report highlights the intricate anatomy of root canals and the challenges they pose for clinicians. A 26-year-old female patient presented to the department with a chief complaint of pain in her left upper back tooth region. After thorough clinical and radiographical examinations, the diagnosis of pulpal necrosis with symptomatic apical periodontitis in the maxillary left first molar was confirmed. An intraoperative cone-beam computed tomography was performed. The axial imaging unveiled that there were, two distal (DB1 and DB2) canals, two palatal (P1 and P2) canals, and three mesiobuccal (MB1, MB2, and MB3) canals. The appearance of a convoluted root canal configuration serves to highlight the inherent complexity that clinicians may encounter during endodontic procedures. However, when this complexity is further compounded by the incident of separation of root canal instruments, the challenges faced by clinicians become significantly more demanding. It exemplifies the increased difficulty posed by the combination of tortuous root canal morphology and the additional complication of instrument separation, highlighting the importance of careful management and precise techniques in such scenarios and the significance of modern adjuncts, into the diagnostic process and magnification in the surgical and endodontic therapy.
