Morphologic Characteristics of C-Shaped Root Canals in Mandibular Second Molars in a Raj Shashi (Bangladesh) Population-An In Vivo Study

Abstract

Aim: The aim of this study was to determine the frequency of C-shaped canals in mandibular second molars in a population in Rajshashi (Bangladesh) and to establish a correlation with a classification of Melton et al. Methodology: 2638 mandibular second molars scheduled for root-canal treatment were examined over a 5-year period. The C-shaped canals were detected by radiographic and clinical examination. Teeth with C-shaped canal systems were categorized by using a classification of Melton. Results: Out of 2638 molars, 354 (13.41%) exhibited C shaped canals. 118 molars were classified as category I, and 70 were considered category II. The remaining 166 cases were classified as category III, with 36 in subdivision I, 51 in subdivision II, and the remaining 79 in subdivision III. Conclusion: The C-shaped canals in mandibular second molars vary considerably in their anatomical configuration with the result that debridement, obturation, and restoration may be difficult. *Correspondence: Dr. Md.
