Abstract

C-shaped canal configurations present significant clinical challenges due to their complex anatomy and difficulty in achieving effective debridement and obturation. This case report describes the endodontic management of a mandibular second molar exhibiting a C-shaped canal morphology. Chemo mechanical preparation was enhanced using liquid EDTA to improve smear layer removal and facilitate penetration of sealer into the dentinal tubules. Obturation was performed with a novel bio ceramic sealer (CanalPro Bioceramic sealer CoItene,SwitzerIand) to achieve superior adaptation and three-dimensional sealing of the irregular canal spaces. This report highlights the importance of advanced irrigation protocols and the use of bio ceramic sealers in managing complex canal anatomies during endodontic therapy.
