This case report aimed to evaluate the influence of C-shaped canal morphology, undetectable on conventional radiographs after failed endodontic treatment, on the retreatment process and treatment outcome. A 43-year-old male patient with a history of leukemia and chemotherapy was referred for evaluation of tooth #36 during a routine chrevealeinadequate previous endodontic treatment and a periapical radiolucent area. Cone-beam computed tomography (CBCT) identified a C-shaped canal morphology. The existing root canal filling material was removed, and endodontic retreatment was performed. The canals were reshaped and obturated appropriately. Follow-up radiographs at 3 and 12 months demonstrated significant periapical healing. This case highlights the importance of CBCT in accurately identifying C-shaped canal morphology and emphasizes that detailed morphological assessment may contribute to the success of endodontic retreatment.
