The aim of this review was to compare the efficiency of cone beam computed tomography (CBCT) and conventional intraoral radiography for the detection of vertical root fractures (VRFs).
Data from comparative and noncomparative studies investigating CBCT, conventional radiography, or both for the diagnosis of VRFs were searched. The main outcome variables were sensitivity, specificity, and accuracy of the techniques. Data were separated into 4 groups: in vivo, ex vivo/untreated teeth, ex vivo/treated teeth, and ex vivo with post. The weighted mean of each parameter was estimated.
Twelve articles were considered for the analysis. There was a large heterogeneity of the characteristics of the studies and a wide variability in outcome variables. No significant differences were found between radiographic techniques.
No superiority of CBCT compared with conventional radiography was found for VRF detection. Adequate choice of voxel size seems to be important when diagnosing VRFs.
本综述旨在比较锥形束计算机断层扫描（CBCT）和传统口腔内放射成像检测垂直根折（VRF）的效率。
检索有关CBCT、传统放射成像或两者用于VRF诊断的比较性和非比较性研究数据。主要结局变量为这些技术的敏感性、特异性和准确性。数据分为4组：体内、离体/未处理牙齿、离体/已处理牙齿和有桩核的离体牙齿。估计每个参数的加权平均值。
12篇文章纳入分析。研究特征存在很大异质性，结局变量差异很大。放射成像技术之间未发现显著差异。
在检测VRF方面，未发现CBCT比传统放射成像具有优越性。诊断VRF时，适当选择体素大小似乎很重要。
