C - shaped canals.

      Аннотация: An accurate knowledge of the morphology of the pulp cavity is rationally crucial before any endodontic procedure. The clinician should be aware about anatomical variation. Knowledge of possible variation is important for successful endodontic treatment. One of the most important anatomic variations is the ‘C’ configuration of the root canal system, the pulp chamber of the C-shaped canal is a single ribbon-shaped orifice with a 180° arc (or more). The C-shaped canal configuration shows an ethnic predilection,and have a high prevalence in mandibular second molars. The C-shaped canal configuration presents with variations in both the number and location of the canals, it is extremely important to perform root canal instrumentation cautiously to avoid any complications and to successfully treat the C-shaped canals.
