The literature search was conducted using electronic web databases like PubMed, Scopus, ScienceDirect and Cochrane with the chosen MeSH key words and data was retrieved until May 2023. Further to perform the statistical analysis, R v 4.3.1 software with \"meta\", \'metafor\" \"metaviz\" \" ggplot2\" package was used, and results were represented by odds ratios (OR) and the percentage of forest plots along a 95 per cent confidence interval (CI).
The total number of studies meeting the inclusion criteria was 13; these studies were conducted on mandibular first premolar using Micro-CT; the total sample size was 1817. To scan the sample, an X-ray micro-focus CT system (Siemens Inveon CT, Erlangen, Germany) was used in four studies and seven different machines were used in the respective studies. Mimics 10.01 software (Materialize, Leuven, Belgium) and NRecon v.1.6.9 software (Bruker, Kontich, Belgium) were commonly operated. The minimum and maximum voxel size ranges between 11.94 and 50 μm. Vertucci\'s classification was frequently used (9), while one study applied Ahmed et al. and Vertucci\'s classification.
This systematic review provides essential information about the root and canal configurations, radicular grooves, accessory canals, and apical foramina through Micro-CT, aiming to improve the accuracy of endodontic treatment and help practitioners.
方法:使用PubMed等电子网络数据库进行文献检索,Scopus,ScienceDirect和Cochrane以及所选择的MeSH关键字和数据一直检索到2023年5月。进一步进行统计分析,带有“meta”的Rv4.3.1软件,使用了\'metafor\"\"metaviz\"\"ggplot2\"包,结果由优势比(OR)和95%置信区间(CI)上的林地百分比表示。
结果:符合纳入标准的研究总数为13;这些研究使用Micro-CT对下颌第一前磨牙进行;总样本量为1817。要扫描样品,X射线微焦点CT系统(SiemensInveonCT,Erlangen,德国)在四项研究中使用,在各自的研究中使用了七台不同的机器。Mimics10.01软件(物化,鲁汶,比利时)和NReconv.1.6.9软件(Bruker,Kontich,比利时)通常经营。最小和最大体素尺寸范围在11.94和50μm之间。Vertucci的分类经常被使用(9),而一项研究应用了艾哈迈德等人。和Vertucci的分类。
结论:本系统综述提供了有关根和管构型的基本信息,神经根沟槽,辅助运河,和根尖孔通过显微CT,旨在提高牙髓治疗的准确性并帮助从业者。
