Aim: The aim of this work was to describe the endodontic management of fi ve C-shaped mandibular molars.

Summary: Five cases of C-shaped mandibular molars in Caucasian patients were referred to the Postgraduate Clinic of the Department of Endodontology over the last year. Pulp necrosis and/or periapical lesions were identifi ed in all cases. The presence of C-shaped root canals was suspected during routine pre-treatment radiographic examination and was verifi ed clinically during probing and scouting of the canals with small hand-fi les and the aid of an operative microscope. A single C-shaped root canal was only found in one case, while slightly varying canal confi gurations were evident in the other four cases. Root canals were instrumented using Hedstroem files in a circumferential filing manner and obturated using warm lateral or vertical condensation. All teeth received permanent restorations and were followed for up to 12 months. None of the cases presented signs of failure within this period.

Conclusions: The C-confi guration is one of the most common variations of root canal anatomy in mandibular molars. Identifi cation and successful treatment of such cases pose a challenge to the clinician. Implications of this anatomical variation may also extend to the prosthetic rehabilitation of these cases.
