The understanding of morphological variations in the canal along with the ability to detect and manage the root canal system are essential for achieving a satisfactory endodontic treatment outcome. This case report presents the endodontic management of a C‐shaped maxillary second molar with five canals. Cone‐beam computerised tomography coupled with a dental operating microscope exhibited remarkable efficacy in the diagnosis, detection and treatment of this irregular morphological root canal system. Clinicians should be alert to anatomic variations in C‐shaped maxillary molars during endodontic treatment, even though these variations rarely occur.
