The aim of the present study was to ascertain frequency and type of radiographic screening in the Danish Dental Service for children. A 5-item questionnaire was sent to each department of public dentistry in the 275 communities of Denmark. A total of 269 questionnaires were returned, four unanswered. Radiographic screening examinations were done on 162 respondents. Of these, 25% had bitewing screening and 25% panoramic screening. Two types of routine radiographic examinations were performed on more than one third of the respondents. The most frequent combination for screening radiography was bitewing and panorama. Even though the risks included in the use of ionizing radiation for dental screening purposes may be considered negligible, it is still ethically correct to avoid unnecessary exposure by a careful selection of patients prior to radiography. As economic support for dental health care had been cut, the radiographic screening procedure must prove itself to be cost/effective to be kept unchanged.
本研究的目的是确定丹麦儿童牙科服务中放射检查的频率和类型。向丹麦275个社区的每个公共牙科部门发送了一份包含5个项目的问卷。共收回269份问卷，4份未回复。对162名受访者进行了放射检查。其中，25%进行了咬合翼片检查，25%进行了全景检查。超过三分之一的受访者进行了两种常规放射检查。最常见的放射检查组合是咬合翼片和全景片。尽管用于牙科筛查目的的电离辐射所带来的风险可能被认为微不足道，但在放射检查前通过仔细选择患者来避免不必要的辐射在伦理上仍然是正确的。由于对牙科保健的经济支持已经削减，放射筛查程序必须证明其具有成本效益才能保持不变。
