Management of c-shape root canal configuration: Case reports

Unusual root canal anatomy always poses a diagnostic and treatment challenge.Therefore a thorough knowledge of root canal anatomical variations along with proper diagnosis, treatment planning and clinical expertise is the key to their successful management. The C-shaped root canal configuration is one such aberrant canal anatomy, common in the mandibular second molar. It often goes undetected and due to the intricate root canal configuration, it is often difficult to negotiate, debride and obturate such canalsleading to failure of root canal treatment.
Case Reports: This article presents management of four different C-shape root canal configurations using the cold lateral condensation and thermoplasticized obturation techniques.
Conclusion: Understanding the anatomical presentations of this variation will enable the clinician to manage these cases effectively. Advanced irrigation and obturation techniques help in managing such anomalous canal configurations.
