Management of a maxillary second premolar with an S-shaped root canal - An endodontic challenge

Knowledge of dental anatomy and its variations is essential for the success of endodontic treatment. Complex and unusual root canal morphology is an often occurring phenomenon. One such variant root canal morphology is the ‘S’ shaped or bayonet shaped root canal. The unique morphology of S-shaped root canals often pose utmost challenges in their endodontic management routine periapical radiographs aids in assessing these morphological variations in the root canal system This case report discusses endodontic treatment of a maxillary second premolar with an ‘S’ shaped root canal.
