Some of the factors influencing the depth of cure of four composite resins of different composition were examined. Knoop hardness measurements were carried out at the surface and 1, 2, 3, 4 and 6 mm below the surface to which the light was applied. The hardness of the composites decreased with increasing depth and shorter exposure times. The composites continued to polymerize after removal of the light source. Composition of the composite resin has a major effect on the surface hardness and depth of polymerization.
研究了影响四种不同成分复合树脂固化深度的一些因素。在光照表面及其下方1、2、3、4和6毫米处进行努氏硬度测量。复合材料的硬度随深度增加和曝光时间缩短而降低。去除光源后，复合材料继续聚合。复合树脂的组成对表面硬度和聚合深度有重大影响。
