Abstract :
Aim and Objective: The purpose of this study was to determine the variations in the number of canals and its morphology in permanent mandibular first molars using cone-beam computed tomography (CBCT) in a subset of Indian population.
Materials and Methods: A total of 350 CBCT scans were collected and evaluated in all three orthogonal planes to determine the number of root canals and study their anatomic variations using Vertucci’s classification.
Statistical Analysis used: The total number of roots and root canals, the root canal configuration, the incidence, and the correlations between left- and right-side occurrences and between males and females were analysed. Statistically significant differences were evaluated using the chi-square test with SPSS 16.0 for Windows (SPSS, Chicago, IL), with significance set at p < 0>
Result: The results of this study showed that predominantly, two thirds of the subjects had type VI mesial canal configuration and two-thirds had type I distal canal configuration. Also there was significant variance in the canal anatomy across gender and age of the subjects.
Conclusion: CBCT is a clinically useful tool in understanding the variations in root canal morphology, which guides in the assessment of the canal morphology aiding in successful root canal treatment.
