A survey was performed among Belgian dentists to evaluate the use and management of digital radiographic equipment. The majority of respondents work as general dental practitioners. One out of eight sets of equipment for extraoral exposures is digital. For intraoral radiography, 30% of the equipment is digital. While exposure time is reduced by about 50% for digital intraoral radiography compared with conventional radiography, no differences can be found between different conventional film speed classes. Appropriate collimation of the radiation beam is only sparingly used. Beam aiming devices to hold the film and position the radiation beam are not used by the majority of dentists. While 25% of the respondents stand behind a protective wall during exposure, 8% of dentists remain next to the patient during exposure while assisting in holding the film inside the mouth. A minority of the latter practitioners wear lead aprons.
对比利时牙医进行了一项调查,以评估数字放射成像设备的使用和管理情况。大多数受访者是普通牙科医生。八分之一的口腔外曝光设备是数字设备。对于口腔内放射成像,30%的设备是数字设备。与传统放射成像相比,数字口腔内放射成像的曝光时间减少了约50%,但不同传统胶片速度等级之间没有差异。辐射束的适当准直很少使用。大多数牙医不使用用于固定胶片和定位辐射束的束流瞄准装置。虽然25%的受访者在曝光时站在防护墙后面,但8%的牙医在曝光时留在患者旁边,同时协助将胶片放入口腔内。后一类从业者中少数人穿着铅围裙。
