In this study, dose area product measurements have been performed to propose diagnostic reference levels (DRLs) in intraoral dental radiology. Measurements were carried out at 60 X-ray units for all types of intraoral examinations performed in clinical routine. The third quartile values calculated range from 26.2 to 87.0 mGy cm(2). The results showed that there exists a large difference between the patient exposures among different dental facilities. It was also observed that dentists working with faster film type or higher tube voltage are not always associated with lower exposure. The study demonstrated the necessity to have the DRLs laid out as guidelines in dental radiology.
在本研究中，已进行剂量面积乘积测量，以提出口腔内牙科放射学的诊断参考水平（DRLs）。在60个X射线设备上对临床常规进行的所有类型口腔内检查进行了测量。计算出的第三四分位数范围为26.2至87.0 mGy cm²。结果表明，不同牙科机构之间患者的照射量存在很大差异。还观察到，使用更快胶片类型或更高管电压的牙医并不总是与更低的照射量相关。该研究表明有必要将DRLs作为牙科放射学的指导方针制定出来。
