In February 1991, about 10 per cent of Ontario's general dentists were polled via a mail survey to gather information about their radiological practices and opinions. Responses were received from 413 out of 537 general practitioners, for a response rate of 77 per cent. A large majority of dentists (86 per cent) have no written office policy and/or protocol for selecting patients for X-ray examination, and just over half (54 per cent) primarily use clinical experience to select patients for these examinations. In the majority of practices (57 per cent), radiographs of asymptomatic recall patients are taken after both their history and clinical examination are complete. A similar percentage (56 per cent) of dentists are opposed to explicit guidelines for radiological examinations.
1991年2月，通过邮件调查对安大略省约10%的普通牙医进行了民意调查，以收集有关他们的放射学实践和意见的信息。537名全科医生中有413人回复，回复率为77%。绝大多数牙医（86%）没有关于选择患者进行X光检查的书面办公室政策和/或协议，略多于一半（54%）的牙医主要根据临床经验选择患者进行这些检查。在大多数诊所（57%）中，无症状复诊患者的X光片是在其病史和临床检查完成后拍摄的。类似比例（56%）的牙医反对针对放射学检查的明确指导方针。
