Demystifying C shaped canals

Introduction: Knowledge of root canal anatomy is essential in order to achieve a successful root canal treatment. C shaped canal anatomy is most commonly seen in mandibular second molars and to some extent mandibular premolars. Such canals are difficult to negotiate, debride/disinfect and obturate due to its high incidence of fins, webs, lateral canals and anastomoses. Inability to identify and debride such canal anatomy may lead to endodontic failure. Case Report: These case series highlights on two different c shaped canals with two different obturation techniques. Conclusion: Complexity of C shaped canal morphology can be managed successfully with proper irrigation and obturation techniques.
