Abstract：
UNASSIGNED: To assess and compare the validity of 2D modified Easy Box and measurement of the Beta angle on standard conventional orthopantomogram (OPG) versus 3D cone-beam computed tomography (CBCT) OPG-constructed view.
UNASSIGNED: A retrospective agreement study.
UNASSIGNED: The aim of this study was to construct an Easy Box on a standard conventional OPG and to validate this novel method by comparing it with the Easy Box method on 3D CBCT. After approval from the Ethics Committee, OPG and CBCT radiographs were obtained for the study from departmental records and five private practices in the same location (Indore, India). The radiographs were selected based on record availability and with written consent from the participants before the commencement of the study. The records were analysed to enable a comparison and to assess the accuracy of Easy Box construction on both 3D CBCT and standard conventional OPG radiographs. The location of the impacted canine within the Easy Box boundaries and the measurement of the Beta angle were determined on both views.
UNASSIGNED: A perfect agreement was obtained for the comparison of 3D Easy Box CBCT analysis with 2D modified Easy Box on OPG for impacted maxillary canines (Kappa = 1.0). A Bland-Altman (LoA) analysis showed no proportional bias in the comparison of the Beta angle on 3D and 2D OPG radiographs.
UNASSIGNED: Beta angle and 2D modified Easy Box on a conventional OPG yield similar results when compared to Easy Box on 3D CBCT OPG-constructed view. The standard OPG was valuable and cost-effective, particularly in the early stages of diagnosis and treatment planning, either as a substitute or when CBCT was unavailable.

摘要：
■评估和比较2D修改的EasyBox的有效性以及在标准常规正像图（OPG）与3D锥形束计算机断层扫描（CBCT）OPG构造视图上测量的Beta角。
■回顾性协议研究。
■这项研究的目的是在标准的常规OPG上构建EasyBox，并通过将其与3DCBCT上的EasyBox方法进行比较来验证这种新颖的方法。伦理委员会批准后,OPG和CBCTX光片是从同一地点的部门记录和五个私人诊所获得的研究(印多尔，印度）。在研究开始之前，根据记录的可用性和参与者的书面同意选择X射线照片。对记录进行了分析，以进行比较，并评估3DCBCT和标准常规OPG射线照片上EasyBox构造的准确性。在两个视图上都确定了受影响的犬科动物在EasyBox边界内的位置和β角的测量值。
■将3DEasyBoxCBCT分析与OPG上的2D改良EasyBox进行比较，获得了完美的一致性（Kappa=1.0）。Bland-Altman（LoA）分析显示，在3D和2DOPG射线照相上的Beta角比较中没有成比例的偏差。
■与3DCBCTOPG构造视图上的EasyBox相比，常规OPG上的Beta角和2D修改的EasyBox产生类似的结果。标准的OPG是有价值和成本效益的，特别是在诊断和治疗计划的早期阶段，作为替代或当CBCT不可用时。
