Abstract:

Introduction: The aim of this study was to identify the root and canal morphology of the maxillary first molars among Malaysians analyzed by Cone-Beam Computed Tomography (CBCT) images. Methods: Maxillary first (n=103) molars from Malaysian patients (n=55) of Malay, Chinese and Indians origins were examined by two endodontists using in vivo CBCT methods. The number and configuration of roots, the number of root canals, and the canal configuration according to Vertucci?s classification were determined. Results: Single roots were not found in maxillary first molars. The incidence of fused roots was 2.4% in the first molars between mesiobuccal and distobuccal roots. In (103) 3-rooted maxillary first molars, additional canals were found in 54.44% of the Mesiobuccal (MB) roots and 0% of the Distobuccal (DB) roots. Bilateral symmetry of the MB roots was found in 82.36% of the first molar. Conclusions: The root and canal configuration of a Malaysian population showed different features from those of other populations. CBCT scans can enhance the understanding of root canal anatomy, with the potential of improving the outcome of endodontic treatment.
