在这项研究中，我们研究了通过树脂复合材料的固化深度和聚合转化率的可见光的透射量的效果。可见光的透射量强烈地依赖于树脂和二氧化硅填料之间存在的折射率差的大小。更具体地说，差异来自于所使用的基础单体的类型。可见光的透射量与树脂复合物的下表面相对于上表面的固化深度和努普硬度比表现出良好的相关性。为了提高空腔底板的聚合转化率，重要的是减小基础树脂和二氧化硅填料之间存在的折射率差。
In this study, we examined the effect of the transmitted amount of visible light through a resin composite on the curing depth and polymerization conversion. Transmitted amount of visible light was strongly dependent on the magnitude of refractive index difference that existed between the resin and silica filler. More specifically, the differences arose from the type of base monomer used. The transmitted amount of visible light exhibited a good correlation with the curing depth and Knoop hardness ratio of the bottom surface against the top surface of the resin composite. To improve the polymerization conversion of the cavity floor, it is important to reduce the refractive index difference that exists between the base resin and silica filler.
