It is more frequent to encounter C shaped canals in Asian populations. This anatomical variation increases the complexity of endodontic treatment, and care should be taken during debridement and obturation of these cases. Things to be observant for are a thin web/fin of tissue in a C configuration, connecting the mesial and […]
