Aim: to investigate the root canal system morphology of the mandibular 1st premolars in an Emirati population using micro computed tomography and conventional radiography. Methodology: Thirty extracted human adult mandibular first premolars were used in this study. The teeth were single-rooted with fully formed apices and had not been endodontically treated, free from caries and large defective restorations. The teeth were collected from Emirati citizens who were referred to various oral surgery clinics around United Arab Emirates. The teeth prepared for scanning using a skyScan micro CT scanner (SkyScan l 172 X-ray micro tomograph, Antwerp, Belgium) at a slice thickness of l l.94[Mu]m. The conventional radiographic images and three-dimensional images were produced by micro CT scanner analyzed independently to record the number of the root, root canals system configuration, presence of C-shaped canal, presence of lateral canals, intercanals communications, number and locations of the apical foramina. Result: 3-sample 10% show deep mesiolingual radicular groove. Variable root canal configurations according to vertucci’s classification were found in teeth as type 1 (70%), type III (6.7%), type V (13.3%) and type VII (3.3%). The examined teeth exhibited two additional canal configurations that did not fit Vertucci's classifications. Type (1-2-3) and type (1-3) and both with three separate apical foramina.
