In 1988, the U.S. Food and Drug Administration issued guidelines to help dentists reduce the amount of X-ray exposure to patients without reducing the quality of care. This study assesses the efficacy of those guidelines. The authors examined 490 patients and ordered radiographs as indicated by the FDA guidelines. Using the guidelines, they ordered a mean of 9.7 radiographs out of a 17-film series, a reduction of 43 percent compared with a full-mouth series. The authors conclude that dentists can reduce a patient's exposure to X-rays by using these guidelines with a low level of missed radiographic findings, most of which would have no effect on the patient's treatment.
1988年，美国食品药品监督管理局发布了指导方针，以帮助牙医在不降低护理质量的情况下减少患者的X射线照射量。本研究评估了这些指导方针的效果。作者检查了490名患者，并按照美国食品药品监督管理局的指导方针要求进行了X光片拍摄。根据这些指导方针，在一套包含17张胶片的全口系列X光片中，他们平均只要求拍摄9.7张，与全口系列相比减少了43%。作者得出结论，牙医通过使用这些指导方针可以减少患者的X射线照射量，同时漏诊X光片结果的情况较少，而且大多数漏诊情况对患者的治疗并无影响。
