摘要
背景：工作长度（WL）的准确测定对根管治疗的成功至关重要。目的：我们的目的是系统地分析体素大小变化对使用锥形束计算机断层扫描（CBCT）估计WL的影响的现有证据。材料与方法：于2022年3月按照特定的纳入和排除标准对PubMed、Scopus、Embase和Web of Science数据库进行电子检索。以英文发表的研究，比较了2个或更多体素大小对人类牙齿WL的CBCT评估与符合纳入条件的物理或电子方法的影响。多名作者独立进行研究选择、数据提取和质量评估。结果：我们纳入了4项研究，涉及220颗牙齿的评估。由于方法学上的不足，对所有研究的偏倚风险都存在一些担忧。体素大小会影响CBCT测量的准确性。所有4项研究都报道了CBCT测量中的体素大小与WL的估计密切相关。最小体素大小与实际长度（AL）的相关性更大。较大的体素尺寸会使精度降低±0.05 mm。这些差异可能与临床无关。锥形束计算机断层扫描评估与电子顶点定位仪（EALs）测量的牙髓白质密切相关，但与根尖周围x线片相比，其辐射剂量更大。结论：基于现有的有限证据，可以不确定地说体素大小可能会影响CBCT的准确性。然而，这些差异可能与临床无关。先前的CBCT扫描可能对WL的估计有用，而不是额外的根尖周x线片。
Effect of the voxel size on the accuracy of endodontic length measurements using cone-beam computed tomography: A systematic review conducted according to the PRISMA guidelines and Cochrane Handbook for Systematic Reviews of Interventions.
Background: The accurate determination of the working length (WL) is imperative for endodontic success.
Objectives: Our objective was to systematically analyze the available evidence on the impact of voxel size variation on the estimation of WL using cone-beam computed tomography (CBCT).
Material and methods: An electronic search of the PubMed, Scopus, Embase, and Web of Science databases was conducted according to specific inclusion and exclusion criteria in March 2022. Studies published in English, comparing the influence of 2 or more voxel sizes on the CBCT assessments of WL in human teeth against physical or electronic methods qualified for inclusion. Multiple authors independently carried out study selection, data extraction and quality assessment.
Results: We included 4 studies involving the assessment of 220 teeth. There were some concerns with regard to the risk of bias in all studies, owing to methodological insufficiencies. Voxel sizes can affect the accuracy of CBCT measurements. All 4 studies reported that the voxel size in CBCT measurements was closely correlated with the estimation of WL. The smallest voxel sizes showed a greater correlation with the actual length (AL). Larger voxel sizes can reduce accuracy by ±0.05 mm. The differences may be clinically irrelevant. Cone-beam computed tomography assessments correlate strongly with the endodontic WL as measured by electronic apex locators (EALs), but are associated with a larger radiation dose in comparison with periapical radiographs.
Conclusions: Based on the limited evidence available, it can be stated with low certainty that voxel sizes may impact CBCT accuracy. However, the differences may be clinically irrelevant. The pre-existing CBCT scans may be useful in the estimation of WL, rather than additional periapical radiographs.
