dc.description.abstractMethods: Two hundred CBCT images with bilateral permanent maxillary first molar were carefully examined by two dentists. Information obtained was on the number and morphology of roots per tooth, the number of canals per root, the root canal configuration in each root using Vertucci’s classification, the relationship between MB2, tooth position and different age groups, and the frequency of C-shaped root canals were determined. Results: The prevalence of three separate roots was 91%. The frequency of three roots where two of them were fused was 8%. Two fused roots were observed in 0.5% of teeth and three fused roots were seen in 0.5% teeth. Regarding the mesiobuccal roots (MBR), the most frequent was Vertucci type IV root canal configuration (42.75%), then type I ( 39.5%),Type II (15%), type III (1.25%); type V (0.75%), and type VI (0, 75%). The occurrence of bilateral MB2 was 65, 75% while the unilateral occurrence of MB2 was 34, 24%.There was no significant difference between 5 age groups (p=0.759, and tooth position p=9977 in regard of presence of MB2. (Distobuccal roots (DBR) displayed a type I configuration in 99.5% of teeth, with only 0.5% of teeth displaying a type IV canal configuration. All palatal roots (PR) had type I canal configuration. No C shaped canals were observed in the sample of 400 permanent maxillary first molars teeth. Conclusion: Cone-beam computed tomography provides valuable information about the anatomy of root and canal morphology which may facilitate root canal therapy.en_ZA
