Management of C-shape root canal configuration: Case reports

Inherent to cleaning and obturation of the root canal system is a thorough knowledge of canal morphology. Recognition of unusual canal configurations and variations is paramount since it has been established that the root with a single tapering canal and apical foramina is the exception rather than the rule. Once recognized the C-shaped canal turns out to be a great challenge in cleaning, debridement, and obturation procedures and so happens because it is unpredictable whether the C-shaped orifice found on the floor of the pulp chamber actually continues to the apical third of the root. C-shaped canals present the clinician with an immense challenge. The high frequency of transverse anastomoses, apical deltas, and lateral canals compels the clinician to use every resource at his disposal to achieve an adequately prepared canal. Thus, a thorough understanding of this configuration with knowledge of challenges appearing to the clinician at each step is necessary. This case report aims to shed light on the complexities of C-shaped canals and emphasize the significance of accurate diagnosis and specialized treatment approaches in achieving successful outcomes.
