To assess the diagnostic quality of images generated using the newly developed digital volume tomography (DVT) system and comparing them with conventional images from patients with maxillofacial trauma.
The study population included 22 male patients aged 18 to 60 years with a history of maxillofacial trauma. Each patient had undergone conventional radiographic and DVT examinations to analyze the number of fracture lines in the jaws and to compare the images for their diagnostic quality by an oral radiologist and a general radiologist using the χ(2) test.
A statistically significant difference was found between the number of fracture lines evaluated on the conventional radiographs and on DVT, especially for condylar head (7) and the midface (4.41 to 4.57), zygomaticomaxillary complex and Le Fort fractures, respectively.
The detection of fracture lines and visualization within the mandibular-maxillary area using DVT was superior to using conventional radiographs.
评估使用新开发的数字容积断层扫描（DVT）系统生成的图像的诊断质量，并将其与颌面部创伤患者的传统图像进行比较。
研究对象包括22名年龄在18至60岁之间有颌面部创伤史的男性患者。每位患者均接受了传统放射成像和DVT检查，以分析颌骨骨折线的数量，并由一名口腔放射科医生和一名普通放射科医生使用χ²检验比较图像的诊断质量。
在传统放射照片和DVT上评估的骨折线数量之间发现了统计学上的显著差异，特别是在髁突头部（7处）以及分别在中面部（4.41至4.57处）、颧上颌复合体和Le Fort骨折方面。
使用DVT检测下颌 - 上颌区域内的骨折线及可视化效果优于使用传统放射照片。
