Abstract |
Introduction: C-shaped root canal configuration is one of the commonly found anatomical challenges during root canal treatment (RCT) of mandibular second molars. Presence of fin or web connecting individual mesial and distal canals in C-shaped root canal system hinders thorough cleaning, shaping, and obturation during RCT. Recognition of C-shaped canal before treatment can facilitate more effective management of root canal system. Objective: To determine the percentage of C-shaped canal in permanent mandibular second molars in patients visiting People’s dental college and hospital for root canal treatment. Materials and Method: An analytical cross-sectional study was conducted from July 2020 to February 2021 at People’s Dental College and Hospital after ethical clearance. Clinical examination was done for 206 mandibular second molars during access opening for the presence of C-shaped anatomy. Categorisation of C-shaped canal morphology was done based on clinical examination at the coronal orifice level. Convenience sampling technique was used for data collection and data were analysed by using SPSS v.16 software. Result: Prevalence of C-shaped canal configuration was seen in 35 (17%) mandibular second molars. Fifteen (15.15%) males and 20 (18.69%) females had C-shaped canal. Among the total, 13 (37.14%) of canals showed category I configuration and 22 (62.86%) showed category II type configuration. Conclusion: There was no significant association with gender and C-shaped canals. Most prevalent canal configuration category found was category I and category II at the orifice level on clinical examination during root canal treatment. |
