Abstract

The natural outcome of dental composite restorations highly depends on the translucency of the enamel layer and fluorescence. This study aimed to evaluate the Translucency Parameter (TP) and Fluorescence Intensity (FI) of five different resin composite systems. Seven discs of each composite brand were prepared in a circular increasing thickness. For TP, a spectrophotometer measured the samples' colors. The color difference within the white/black backgrounds obtained the translucency parameter. For FI, samples were exposed to UV light, and ten photographs per group were taken. Each specimen was analyzed digitally. A mixed model analysis to a 95% confidence level analyzed groups differences. Higher values of TP were observed for ED and EL, followed by FZ. The lowest values were observed for EO and FO. FI values descending order was EL>FO>EO>ED>FZ. The composition of fillers and organic matrix influenced the behavior of fluorescence and translucency of resin composites. Resin composite, fluorescence, color, translucency parameter.

摘要

牙科复合树脂修复体的自然效果高度依赖于釉质层的透明度和荧光。本研究旨在评估五种不同树脂复合体系的透明度参数（TP）和荧光强度（FI）。每个复合品牌制备七个厚度逐渐增加的圆形圆盘。对于TP，用分光光度计测量样品的颜色。在白色/黑色背景下的色差得出透明度参数。对于FI，将样品暴露于紫外光下，每组拍摄十张照片。每个标本进行数字分析。采用95%置信水平的混合模型分析组间差异。ED和EL的TP值较高，其次是FZ。EO和FO的TP值最低。FI值的降序排列为EL>FO>EO>ED>FZ。填料和有机基质的组成影响树脂复合材料的荧光和透明度行为。树脂复合材料、荧光、颜色、透明度参数。
