Objective: The C-shaped root canal is a unique root morphology that is mostly present in mandibular second permanent molars. C-shaped root canal networks may make endodontic procedures more difficult due to their structure's complexity. For accurate diagnosis and successful treatment, a complete grasp of root canal morphology is required. This survey aims to summarize current knowledge, attitude and practice based survey on the incidence of c shaped canals in the mandibular molars among undergraduate students.
