The object of this study was to analyze two measuring methods for determining the amount of generalized wear of dental materials. Using a recently developed three-body wear testing machine, generalized wear defect was produced on the surface of various dental materials. Although the generalized wear was defined as the depth of the enamel exposed at the cavity margin for both methods, this depth was measured with two different devices. One is an image-analyzer and the other was a profilometer. From the results of this study, it was confirmed that measurement by means of profilometer gave almost the same wear values with those by image-analyzer. In addition, the measurement by profilometer seemed to be more precise and not very much sophisticated.
本研究的目的是分析两种用于测定牙科材料总体磨损量的测量方法。使用最近开发的三体磨损试验机，在各种牙科材料表面产生总体磨损缺陷。虽然两种方法都将总体磨损定义为洞缘处暴露的牙釉质深度，但该深度是用两种不同的设备测量的。一种是图像分析仪，另一种是轮廓仪。从本研究结果可知，轮廓仪测量得到的磨损值与图像分析仪测量得到的磨损值几乎相同。此外，轮廓仪测量似乎更精确且不太复杂。
