A good knowledge of the internal dental anatomy and its variations is an absolute necessity for successful endodontic therapy. In cases where variations are not detected therapeutic failure can be expected to occur. The “C-shaped” configuration is among the various anatomical configurations of the root canal system, and this configuration was originally described by Cooke & Cox in 1979(1). C-shaped root canals are characterized by a single ribbon-shaped orifice of 180o (or more). The C-shaped canal system can assume different anatomical variations (2-4). Such canal systems are a significant ethnic variation and are predominantly observed in Asian people (31.5% to 44.5%), (5) but are also present in Caucasian populations (2.7%) (1). C-shaped root canals are commonly observed in mandibular permanent second molars(6) at a frequency of 39%, alUvod
