Introduction: Thorough knowledge of the root canal morphology is essential for successful endodontic therapy. C-shaped canal configuration is commonly seen in mandibular second molars. These canals are challenging to negotiate, debride, and obturate because of the high incidence of anastomoses, lateral canals, and apical deltas. The inability to detect and debride C-shaped canal anatomy can lead to endodontic failure. Case report: This case report highlights the management of a case of C- shaped canal configurations using thermoplastics gutta-percha technique. Conclusion: Complex intricacies and diverse morphology of C shaped canals can be managed with advanced irrigation and obturation techniques.
