Guidelines for the selection of patients requiring radiological examination have recently been published in Canada and the United States. The purpose of this paper, the second in a three-part series on the results of a questionnaire to Ontario general practitioners, is to compare bitewing use in Ontario against the U.S. guidelines. This questionnaire determined the frequency of recall bitewing examination for low and high caries risk patients, as well as the factors that influence the diagnostic and treatment decisions of the responding dentists. For example, 49 to 78 per cent of dentists order recall bitewings--in accordance with U.S. guidelines--for their patients in individual low caries risk categories. Similarly, 49 to 88 per cent of dentists order recall bitewings for individual patients in high caries risk categories, which is also consistent with the U.S. guidelines. However, across all low and high caries risk groups of patients, the percentages of dentists who followed the recommended guidelines were 34 and 15 per cent, respectively. The responding dentists' estimates of the length of time required for caries to progress through enamel are indirectly associated with the interval prescribed for recall bitewing examination.
加拿大和美国最近发布了关于选择需要进行放射学检查患者的指南。本文是关于安大略省全科医生问卷调查结果的三篇系列文章中的第二篇，目的是将安大略省咬合翼片的使用情况与美国指南进行比较。这份问卷确定了低龋风险和高龋风险患者定期咬合翼片检查的频率，以及影响参与调查牙医诊断和治疗决策的因素。例如，按照美国指南，49%至78%的牙医会为处于个体低龋风险类别的患者安排定期咬合翼片检查。同样，49%至88%的牙医会为处于高龋风险类别的个体患者安排定期咬合翼片检查，这也与美国指南一致。然而，在所有低龋风险和高龋风险患者组中，遵循推荐指南的牙医比例分别为34%和15%。参与调查的牙医对龋齿穿透牙釉质所需时间的估计与规定的定期咬合翼片检查间隔间接相关。
