To thoroughly plan and execute any dental treatment, the anatomy of the dental root canals is of prime significance. Hence, in this systemic review, we intend to evaluate the cone beam computed and micro-computed tomographic presentations of the root canal morphologies of the secondary teeth.
We conducted the search for the data from the online sources such as the "EMBASE," "Pubmed," "Scopus," and other sources. Only human studies were collected. Terms searched were cone beam computed tomography (CBCT), micro-computed tomography, permanent teeth, and root canal morphology. The data extraction and meta-analysis were based on the PRISMA guidelines.
A total of 170 studies were initially considered for the study. After the application of the inclusion and the exclusion criteria, only ten studies were qualified for the study. In 2 studies, the comparison was done between the conical beam and the microtomograhic views for assessing the root canal anatomies. There were, however, three studies that did not conclude any significant relation between the two imaging systems. When the risk of bias was calculated for the ten studies, there were only low and moderate for the ten included studies. The pooled prevalence among the genders were 21.4% (14.0%-24.6% confidence interval [CI] 95%) and 25.3% (20.0%-30.7% CI 95%), respectively, with high heterogeneity values (= 99.30% and 98.50%, respectively), but no statistical significance ( > 0.05).
Both the imaging systems CBCT and the microtomography can be used with accuracy in the evaluation of the anatomic variations of the human root canal. However, a definition is dependent on the voxel size.
为了全面规划和实施任何牙科治疗，牙根根管的解剖结构至关重要。因此，在本系统评价中，我们旨在评估锥形束计算机断层扫描和显微计算机断层扫描对恒牙根管形态的显示情况。
我们从“EMBASE”“Pubmed”“Scopus”等在线资源以及其他来源搜索数据。仅收集人体研究。搜索的关键词为锥形束计算机断层扫描（CBCT）、显微计算机断层扫描、恒牙和根管形态。数据提取和荟萃分析基于PRISMA指南。
最初共考虑了170项研究用于本研究。应用纳入和排除标准后，仅有10项研究符合要求。在2项研究中，对锥形束和显微断层扫描视图进行了比较以评估根管解剖结构。然而，有3项研究未得出两种成像系统之间存在任何显著关系的结论。在计算这10项研究的偏倚风险时，纳入的10项研究中只有低风险和中等风险。不同性别的合并患病率分别为21.4%（95%置信区间[CI]为14.0%-24.6%）和25.3%（95%CI为20.0%-30.7%），异质性值较高（分别为99.30%和98.50%），但无统计学意义（>0.05）。
CBCT和显微断层扫描这两种成像系统均可准确用于评估人类根管的解剖变异。然而，其清晰度取决于体素大小。
