Abstract：
This systematic review\'s objective was to conduct a complete analysis of the literature on the root canal morphology using advanced micro-computed tomography. The electronic web databases PubMed, Scopus, and Cochrane were examined for research papers concerning the chosen keywords, evaluating the root canal morphology using Micro-CT, published up to 2021. The articles were searched using MeSH keywords and searched digitally on four specialty journal websites. DARE2 extended (Database of Attributes of Reviews of Effects) was used to assess bias risk. The information was gathered from 18 published studies that strictly met the criteria for inclusion. In the included studies, a total of 6696 samples were studied. The studies were conducted on either maxillary (n-2222) or mandibular teeth (n-3760), permanent anteriors (n-625), and Third molars (n-89). To scan samples, a Scanco Medical machine in was used in 10 studies, Bruker Micro-CT in 34, and seven other machines were utilized in the rest. Bruker Micro-CT software from Kontich, Belgium, VG-Studio Max 2.2 software from Volume Graphics, Heidelberg, Germany, was the most commonly used software. The minimum Voxel size (resolution) adopted in the included studies was 11.6 µm. However, 60 µm was the maximum. Most studies classified the root canal morphology using Vertucci\'s classification system (n-16) and the four-digit system (n-6).
摘要：
本系统综述的目的是使用先进的显微计算机断层扫描对根管形态学的文献进行全面分析。电子网络数据库PubMed，Scopus,检查了Cochrane关于所选关键词的研究论文，使用Micro-CT评估根管形态，发布至2021年。使用MeSH关键字搜索文章，并在四个专业期刊网站上进行数字搜索。扩展的DARE2（影响评价属性数据库）用于评估偏倚风险。这些信息来自18项严格符合纳入标准的已发表研究。在纳入的研究中，共研究了6696个样本。这些研究是在上颌（n-2222）或下颌（n-3760）牙齿上进行的，永久性前舱（n-625），和第三磨牙（n-89）。要扫描样品，在10项研究中使用了一台Scanco医疗机器，34年的BrukerMicro-CT，其余的则使用了其他七台机器。Kontich的BrukerMicro-CT软件，比利时,VolumeGraphics的VG-StudioMax2.2软件，海德堡,德国,是最常用的软件。纳入研究中采用的最小体素大小（分辨率）为11.6µm。然而,最大为60μm。大多数研究使用Vertucci的分类系统（n-16）和四位数系统（n-6）对根管形态进行分类。
