Abstract
One of the commonest anatomical variations of the root canal morphology includes the C- shaped canal configuration, frequently observed in second mandibular molars, but may be detected in other tooth morphotypes also. Very frequently, the first mandibular molars necessitate an endodontic therapy as they are often caries-prone and tends to be the first erupting permanent posteriors. The complexities of this root canal diversity might often make canal negotiation, debridement, and obturation cumbersome for the clinician. The detection and exploration of the fan-shaped regions and intricacy of the C-shaped morphology can be enhanced by radiographic and clinical diagnostics. Hand as well as rotary instruments, together with sonics/ultrasonics, could be used to adequately manage this unusual canal arrangement. The current case report describes the diagnosis and management of an unfamiliar C-shaped canal morphology in first mandibular molar and emphasizes the imperative role of CBCT, improved magnifying aids like microscope and good choice of an endodontic sealer for its efficient handling
