The in vitro depth of cure of a visible-light-activated microfilled composite, as influenced by backing reflectance and mold size, was investigated using microhardness measurements. More extensive polymerization was obtained with higher values of backing reflectance. Mold size larger than the cross-sectional area of the photo-activating beam also increased the degree of polymerization. Backing reflectance and mold size are influential factors and need to be defined in depth-of-cure evaluations if in vitro measurements are to be valid predictors of clinical performance.
利用显微硬度测量法，研究了背衬反射率和模具尺寸对可见光激活微填料复合材料体外固化深度的影响。背衬反射率值越高，聚合越充分。大于光激活光束横截面积的模具尺寸也增加了聚合程度。背衬反射率和模具尺寸是影响因素，如果体外测量要成为临床性能的有效预测指标，那么在固化深度评估中需要对其进行深入界定。
