ABSTRACT
Background: Mandibular second molars frequently have a C-shaped canal. Apical deltas, lateral canals, and transverse anastomoses are frequently present, making it challenging to explore, debride, and obturate. Failure of the root canal treatment may result from failure to identify and clean up the root canal system. Case report: This case study describes the management of three distinct C-shaped root canal configurations employing thermoplasticized obturation procedures. Case management: The mesial and distal roots were united and had a conical form on the preoperative radiograph. An access cavity was made after the appropriate isolation and anesthetic, and working length was measured using an apex locator. The Protaper Gold and OneCurve rotary file systems were used to prepare the canals, and 5% sodium hypochlorite was used as an endodontic irrigant and an endo activator to activate them. A medication called calcium hydroxide was administered intravenously. After one week, obturation with warm vertical compaction using thermoplasticized gutta-percha. Post-endodontic restoration was done with fiber-reinforced resin composite. Conclusion: Knowledge of aberrant root canal anatomy is essential for successful endodontic therapy. The C-shaped canal's unique morphology may be managed using chemomechanical, advanced irrigation, and obturation techniques.
