Categorization and Management of Various Types of C-Shaped Canals: Two Case Reports.

This case report presents the categorization and management of two cases of C-shaped canals in need of root canal treatment, based on the available classification systems. The prediction of C-shaped root canal morphology using radiography and clinical picture is possible through the application of the classification schemes proposed in literature. A modified cold lateral compaction technique is described for obturation of C-shaped canals partly united by a narrow isthmus.
