The purpose of this study was to determine any discrepancies in the outputs of five commercial dental radiometers and also to evaluate the accuracy of these devices using a laboratory-grade spectroradiometer. The power densities of 12 different curing light sources were repeatedly measured for a total of five times using each radiometer in a random order. The emission spectra of all of the curing light sources were also measured using the spectroradiometer, and the integral value of each spectrum was calculated to determine the genuine power densities, which were then compared to the displayed power densities measured by the dental radiometers. The displayed values of power density were various and were dependent on the brand of radiometer, and this may be because each radiometer has a different wavelength sensitivity. These results cast doubt upon the accuracy of commercially available dental radiometers.
本研究的目的是确定五台商用牙科辐射计的输出是否存在差异，并使用实验室级光谱辐射计评估这些设备的准确性。使用每台辐射计以随机顺序对12种不同固化光源的功率密度重复测量5次。还使用光谱辐射计测量所有固化光源的发射光谱，并计算每个光谱的积分值以确定真实功率密度，然后将其与牙科辐射计测量的显示功率密度进行比较。功率密度的显示值各不相同，并且取决于辐射计的品牌，这可能是因为每个辐射计具有不同的波长灵敏度。这些结果使人对市售牙科辐射计的准确性产生怀疑。
