“…Another micro-CT study included in this systematic review was conducted on maxillary first molars to detect extra root canal orifices which is usually difficult due to dentin ledge that can cover the floor of pulp chamber [ 90 ]. Commonly it is approved that maxillary first molars have three or four pulp canals, but using 3D images by micro-CT this study evaluated the presence of three (7.01%), four (47.37%), five (35.09%) and six (10.53%) pulp canal orifices [ 90 ].…”

Introduction Root canal treatment procedures require a thorough understanding of root and canal anatomy. The purpose of this systematic review was to examine the morphological differences of teeth root and their canals assessed using cone-beam computed and micro-computed tomography in Saudi Arabian population. Methodology An electronic search was conducted in PubMed / Medline, Scopus, Google Scholar, and Web of Science databases until January 2023 to retrieve related studies. “Root canal morphology,” “Saudi Arabia,” “Micro-CT,” and “cone-beam computed tomography” were used as keywords. A modified version of previously published risk of bias assessment tool was used to determine the quality assessment of included studies. Results The literature search revealed 47 studies that matched the criteria for inclusion, out of which 44 studies used cone beam computed tomography (CBCT) and three were micro-computed tomography (micro-CT) studies. According to the modified version of risk of bias assessment tool, the studies were categorized as low, moderate, and high risk of bias. A total of 47,612 samples were included which comprised of either maxillary teeth (5,412), or mandibular teeth (20,572), and mixed teeth (21,327). 265 samples were used in micro-CT studies while 47,347 teeth samples were used in CBCT studies. Among the CBCT studies, except for three, all the studies were retrospective studies. Frequently used imaging machine and software were 3D Accuitomo 170 and Morita’s i-Dixel 3D imaging software respectively. Minimum and maximum voxel sizes were 75 and 300 μm, Vertucci’s classification was mostly used to classify the root canal morphology of the teeth. The included micro-CT studies were in-vitro studies where SkyScan 1172 X-ray scanner was the imaging machine with pixel size ranging between 13.4 and 27.4 μm. Vertucci, Ahmed et al. and Pomeranz et al. classifications were applied to classify the root canal morphology. Conclusion This systematic review revealed wide variations in root and canal morphology of Saudi population using high resolution imaging techniques. Clinicians should be aware of the common and unusual root and canal anatomy before commencing root canal treatment. Future micro-CT studies are needed to provide additional qualitative and quantitative data presentations.

Introduction: The morphological characteristics of root canals may show divergent results for different populations. The precise knowledge of the tooth anatomy has a great importance from the point-of-view of the endodontic treatment. The aim of the present study is to map the root canal morphology and anatomical variations of the maxillary first molars on a local population, as well as the study of the possible communications between the canals. Material and method: CBCT images were evaluated during the study using the Ez3D Plus – 3D Imaging Dental Software. Teeth sections were examined in three directions: axial, saggittal and coronal. In case of maxillary first molars with four root canals the presence of an isthmus was evaluated between the two mesiobuccal root canals, on transversal sections. Results: In 23.72% of the cases three root canals were found, while in 76.27% of the cases four root canals were found. No statistically significant differences were found between genders. Among the mesiobuccal root canals the communication was found mostly in the middle third and this was extended to the apical third. Conclusions: Since the communication between the two mesiobuccal root canals is present in most of the cases, the clinicians have to be aware of this in order to achieve a successful therapy. In the majority of the cases the four root canal morphological variation is more freqvent than the three canal variation, but with aging this freqvency is reduced.
