Effective endodontic therapy treatment necessitates by shaping and thorough cleaning of root canalâs structure, which often presents multiple curvatures that complicate instrumentation. In both the cases discussed in the case report, there was sudden sharp pain on consumption of hot and cold food stuffs. On clinical examination, deep proximal caries in maxillary second premolar was seen in both the cases. Teeth were tender on percussion. Radiographic evaluation showed caries involving pulp, with periodontal ligament widening and sharp curvature in apical third region of the roots. These curvatures can lead to procedural errors like ledges and obstructions. This case report highlights the challenges in treatment of moderately to severely bent root canals (tooth number 15 and 25 respectively), emphasizing the importance of understanding root and canal morphology and use of appropriate instruments like pre-curved Ni-Ti files during canal shaping.
