Buccal cortical bone dimensions are crucial in dental radiology, as they impact orthodontic treatment outcomes. Changes in alveolar bone dimensions can result in malocclusion and require interdisciplinary approaches for correction. The accurate quantification of buccal bone dimensions is crucial for appropriate treatment planning and avoiding medico-legal issues. This study aimed to compare buccal bone height measurements between three-dimensional (3D) digital imaging and communications in medicine (DICOM) data and portable document format (PDF) cone beam computer topography reports for mandibular frontal teeth, testing the hypothesis of no difference in values between the two modalities. Each of the five observers performed a total of 720 height measurements (360 by DICOM and 360 by PDF), yielding a total of 3600 measurements overall. Compared with the DICOM format, using PDF files was associated with a significantly greater rate of inability to carry out the measurements (8.8% vs. 3%, respectively, < 0.001, chi-square). The average buccal bone height measured in the DICOM was 11.51 mm, which was significantly greater than the 10.35 mm measured in the PDF ( < 0.001). The mean height measured by the DICOM was consistently greater than that measured by the PDF, with highly significant differences in the findings of four of the examiners ( < 0.001). Viewing modality significantly affected the height of the buccal bone in the frontal mandibular area. Compared with the generated PDF reports, the 3D DICOM viewer performed better than the printed PDF and enabled more measurements in the target area.
颊侧皮质骨尺寸在口腔放射学中至关重要，因为它们会影响正畸治疗效果。牙槽骨尺寸的变化可导致错牙合畸形，需要采用多学科方法进行矫正。准确量化颊侧骨尺寸对于制定合适的治疗计划和避免医疗法律问题至关重要。本研究旨在比较三维（3D）医学数字成像和通信（DICOM）数据与便携式文档格式（PDF）锥形束计算机断层扫描报告中下颌前牙颊侧骨高度的测量结果，检验两种方式测量值无差异的假设。五名观察者每人总共进行了720次高度测量（DICOM方式360次，PDF方式360次），总共进行了3600次测量。与DICOM格式相比，使用PDF文件时无法进行测量的比例显著更高（分别为8.8%和3%，<0.001，卡方检验）。DICOM测量的颊侧骨平均高度为11.51毫米，显著高于PDF测量的10.35毫米（<0.001）。DICOM测量的平均高度始终高于PDF测量的平均高度，四名检查者的测量结果存在高度显著差异（<0.001）。观察方式对下颌前部区域颊侧骨的高度有显著影响。与生成的PDF报告相比，3D DICOM查看器比打印的PDF表现更好，能够在目标区域进行更多测量。
