Abstract

Data from dental intraoral radiography quality controls was gathered from 1201 units (22% of the licensed X-ray units existing in Portugal), using film and digital image systems, between 2016 and 2018. The median incident air KERMA for standard superior molar tooth was evaluated in 0.9 mGy with the value of 1.3 mGy as the upper quartile. Comparisons with a 1990 published survey from dental exposures in Portugal were made. A 85% reduction for incident air KERMA per exposure was observed (6.0 mGy for the 1990 survey), which can be attributed to technical advances in the X-ray image receptors, as well as the implementation of legal requirements for technical acceptability of radiological units. It was also observed an increase of X-ray exams, which is related to an increase of dental practitioners, available radiological equipment and the level of dental healthcare.

摘要

2016年至2018年期间，从1201个单位（占葡萄牙现有许可X射线单位的22%）收集了口腔内牙科X线摄影质量控制的数据，这些单位使用了胶片和数字图像系统。对标准上颌磨牙的空气比释动能率中位数进行了评估，结果为0.9毫戈瑞，上四分位数为1.3毫戈瑞。与1990年发表的葡萄牙牙科照射调查进行了比较。观察到每次照射的空气比释动能率降低了85%（1990年调查为6.0毫戈瑞），这可归因于X射线图像接收器的技术进步以及对放射单位技术可接受性的法律要求的实施。还观察到X射线检查有所增加，这与牙科从业者、可用放射设备以及牙科医疗保健水平的提高有关。
