Prepared samples of light-activated composite were cured by transillumination of tooth tissue in healthy volunteers. Positioning of the samples and the direction of illumination was designed to simulate curing during direct bonding. The effectiveness of curing was investigated by determination of surface microhardness. The degree of polymerization of the specimens cured by transillumination was found to be reduced compared to the control samples cured by direct exposure to the light source.
在健康志愿者中，通过对牙齿组织进行透照来固化光活化复合材料的制备样本。样本的定位和光照方向旨在模拟直接粘结过程中的固化。通过测定表面显微硬度来研究固化效果。结果发现，与通过直接暴露于光源而固化的对照样本相比，经透照固化的样本的聚合度有所降低。
