作者考察了两类可见光固化复合树脂各色材料的双键转化度、显微硬度和固化深度。结果表明，复合树脂深层材料的聚合明显受树脂颜色的影响。深色树脂与浅色树脂相比，其３ｍｍ厚样品底面的转化度和显微硬度都明显降低。深色树脂的固化深度也明显低于浅色树脂。
The authors investigated the double bond conversion, microhardness and cure depth of the two types of visible light curable composite resins. The results show that the composite resin deep material is obviously affected by the resin color. Dark resin and light-colored resin, the 3mm thick sample bottom surface of the degree of conversion and microhardness were significantly reduced. Dark resin curing depth is also significantly lower than the light-colored resin.
