Abstract：
BACKGROUND: 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.
METHODS: 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.
CONCLUSIONS: 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.

摘要：
背景：根管治疗程序需要彻底了解根和管的解剖结构。这项系统评价的目的是研究沙特阿拉伯人群中使用锥形束计算机和微型计算机断层扫描评估的牙根及其根管的形态差异。
方法：在PubMed/Medline进行了电子搜索，Scopus,谷歌学者，和WebofScience数据库，直到2023年1月才能检索相关研究。“根管形态学，\"\"沙特阿拉伯,\"\"Micro-CT,使用“”和“锥形束计算机断层扫描”作为关键字。以前发表的偏倚风险评估工具的修改版本用于确定纳入研究的质量评估。
结果：文献检索显示有47项研究符合纳入标准，其中44项研究使用锥形束计算机断层扫描（CBCT），3项为微型计算机断层扫描（micro-CT）研究。根据修正版本的偏差风险评估工具，这些研究被归类为低，中度,和高风险的偏见。总共包括47,612个样本，其中包括任一上颌牙齿（5,412个），或下颌牙齿（20,572），和混合牙齿（21,327）。265个样本用于显微CT研究，而47,347个牙齿样本用于CBCT研究。在CBCT研究中，除了三个,所有研究均为回顾性研究.常用的成像机和软件分别是3DAccuitomo170和Morita的i-Dixel3D成像软件。最小和最大体素尺寸为75和300μm，Vertucci的分类主要用于对牙齿的根管形态进行分类。包括的显微CT研究是体外研究，其中SkyScan1172X射线扫描仪是成像机，像素大小在13.4和27.4μm之间。Vertucci,艾哈迈德等人。和Pomeranz等人。应用分类法对根管形态进行分类。
结论：本系统综述使用高分辨率成像技术揭示了沙特人群根和管形态的广泛变化。在开始根管治疗之前，临床医生应了解常见和不寻常的根管解剖结构。未来的显微CT研究需要提供额外的定性和定量数据呈现。
