A new dental x-ray fluorographic unit has been developed. This unit is composed of small intraoral x-ray tube, a compact x-ray image intensifier, and a high-resolution TV system. The purposes for developing this equipment were to (1) directly observe the tooth during endodontic procedures and (2) reduce x-ray exposure to the patient and the dentist. The radiation exposure can be reduced to about 1/600 the exposure used with conventional dental film. In clinical trials, a satisfactory fluorographic dental image for endodontic treatment was obtained with this new device.
一种新型牙科X射线荧光摄影装置已研制成功。该装置由小型口腔内X射线管、紧凑型X射线影像增强器和高分辨率电视系统组成。开发此设备的目的是：（1）在牙髓治疗过程中直接观察牙齿；（2）减少患者和牙医所接受的X射线照射。辐射暴露量可降低至传统牙科胶片所用照射量的约1/600。在临床试验中，使用这种新装置获得了用于牙髓治疗的令人满意的荧光摄影牙齿图像。
