Root Canal Morphology of Maxillary First and Second Molars in a Qatari Population: A Cone-Beam Computed Tomography Study

Abstract Objective The purpose of this study was to evaluate the number roots and canal configuration maxillary first second molars in Qatari population. Materials Methods A total 544 cone-beam computed tomography (CBCT) records patients were included study. CBCT images reviewed by two endodontists. age, sex, bilateral symmetry, root number, according Vertucci tabulated. Results About 97.5% had three 2.5% roots. Maxillary molar showed 88.2% roots, 7.3% 3.3% single root, 1.2% four For molars, most common classifications for mesiobuccal type IV (2-2, 35.9%) II (2-1, 21.1%). 27%), III (1-2-1, 21.3%), I (1, 19.6%), 18.9%). In molar, 53.1% right is different from left 60.2% left. Conclusions population, are molars. Mesiobuccal predominant with (2-2) (2-1). variable classification. High asymmetry found same individuals that should be considered during treatment opposite
