The purpose of this in vivo study was to verify the accuracy of cone beam computed tomography (CBCT) in the measurement of horizontal periodontal bone defects. Six patients with periodontitis were selected, and eight maxillary molars were assessed. A total of 72 measurements were performed. The images were obtained using CBCT, and measurements were performed using the appropriate software. Periodontal bone defects were measured during the surgical intervention using the cementoenamel junction as the reference point. There were no statistically significant differences between clinical and CBCT measurements (P > .05). CBCT accurately reproduced the clinical measurement of horizontal periodontal bone defects.
本体内研究的目的是验证锥形束计算机断层扫描（CBCT）在测量水平牙周骨缺损方面的准确性。选择了6名牙周炎患者，并评估了8颗上颌磨牙。总共进行了72次测量。使用CBCT获取图像，并使用适当的软件进行测量。在手术干预期间，以牙骨质釉质界为参考点测量牙周骨缺损。临床测量和CBCT测量之间无统计学显著差异（P>.05）。CBCT准确再现了水平牙周骨缺损的临床测量结果。
