A survey of dental assisting programs revealed little standardization of student requirements for dental radiography in the United States. Areas for concern were (1) the high proportion of programs in which classmates exposed one another to ionizing radiation for training purposes and (2) the continued use of closed cones in some cases. Preclinical laboratories in radiography were, on average, of considerably longer duration than those previously reported for dental students. Conversely, clinical requirements in intraoral techniques were less for dental assisting students than is the case for dental students. Available methods of reducing patient exposure to ionizing radiation are not being fully implemented.
一项对牙科辅助课程的调查显示，美国牙科放射摄影学生要求的标准化程度很低。令人担忧的领域包括：（1）很大一部分课程中，同学之间为了训练目的互相接受电离辐射；（2）在某些情况下仍继续使用封闭式牙片夹。放射摄影的临床前实验室平均时长比之前报道的牙科学生的临床前实验室时长长得多。相反，牙科辅助专业学生在口腔内技术方面的临床要求低于牙科专业学生。现有的减少患者接受电离辐射的方法尚未得到充分实施。
