{"title":"Comparison of 3D Easy Box cone-beam computed tomography analysis with 2D Modified Easy Box on OPG as a prognostic tool for impacted maxillary canines: A pilot study.","authors":"Rochelle Dias, Himanshu Kanungo, Mukesh Gupta, Kratika Mishra, Akanksha Soni, Aayush Jaiswal","doi":"10.1177/14653125241242138","DOIUrl":"10.1177/14653125241242138","url":null,"abstract":"<p><strong>Objective: </strong>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.</p><p><strong>Design: </strong>A retrospective agreement study.</p><p><strong>Methods: </strong>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.</p><p><strong>Results: </strong>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).
