The purpose of this study was to measure DAP (Dose Area Product) values in panoramic radiology with the use of a DAP meter, to determine corresponding reference levels, and to compare DAP between panoramic and intraoral radiology. DAP was measured in 62 panoramic X-ray units for 3 types of exposure (male, female and child) and in 20 intraoral X-ray units of 50, 60 and 70 kVp. DAP reference levels were 117 mGy cm2, 97 mGy cm2 and 77 mGy cm2 for exposure of a male, female and child respectively. Results showed that DAP from a panoramic dental examination is approximately twice that from a single intraoral examination. DAP meter is a very convenient and easy to use tool for patient dosimetry and for the establishment of reference levels in dental panoramic radiology.
本研究的目的是使用剂量面积积（DAP）仪测量全景放射成像中的DAP值，确定相应的参考水平，并比较全景放射成像和口腔内放射成像之间的DAP。在62台全景X射线设备上针对3种曝光类型（男性、女性和儿童）测量了DAP，并在20台50、60和70 kVp的口腔内X射线设备上进行了测量。男性、女性和儿童曝光的DAP参考水平分别为117 mGy cm²、97 mGy cm²和77 mGy cm²。结果表明，全景牙科检查的DAP约为单次口腔内检查的两倍。DAP仪是用于患者剂量测定以及在牙科全景放射成像中建立参考水平的非常方便且易于使用的工具。
