Abstract

A new experimental intraoral dental xeroradiographic system was evaluated for future application in dentistry. Similar projections on conventional film radiographs and experimental dental xeroradiographs were compared visually and radiation exposure for both techniques was measured by thermoluminescent dosimetry. The xeroradiographic system was judged superior for imaging most structures, especially oral soft tissues, subtle bony abnormalities, and fine calculus deposits. Furthermore, xeroradiography requires only one third the radiation exposure of corresponding conventional film techniques. Dental xeroradiography appears to have great promise in radiographic interpretation of oral disease.

摘要

一种新型的实验性口腔内牙科干板X线照相系统被评估，以便未来在牙科领域应用。对传统胶片X线照片和实验性牙科干板X线照片上的类似投影进行了视觉比较，并通过热释光剂量测定法测量了两种技术的辐射暴露量。结果判断，干板X线照相系统在对大多数结构成像方面表现更优，尤其是口腔软组织、细微的骨质异常和细小的牙结石沉积。此外，干板X线照相所需的辐射暴露量仅为相应传统胶片技术的三分之一。牙科干板X线照相在口腔疾病的影像学诊断方面似乎很有前景。
