目标。测定树脂基复合材料（rbc）和玻璃离子聚合物水泥（gic）在不同染色剂和食物模拟溶液（FSS）浸泡后的表面染色程度。使用了六种牙色修复材料：光固化微填充红细胞（Durafil, Kulzer），光固化微玻璃红细胞（Charisma, Kulzer），酸改性红细胞（F2000, 3M/ESPE），常规GIC （Fuji IX， GC）和两种树脂改性GIC （Fuji 11 LC， GC; Photac Fit, 3M/ESPE）。圆盘状的样品被制备和测试，要么用基体抛光，要么用湿碳化硅纸抛光，砂砾达2000。所有人。标本在37℃蒸馏水中浸泡1周，然后用3种不同的FSS（水、10%乙醇、Crodamol GTCC）和5种染色剂（红酒、咖啡、茶、酱油和可乐）再浸泡2周。每种材料的每个染色都测试了三个样品。每次处理后用分光光度计测量颜色系数（CIE L* a* b*）。颜色变化（Delta E-n）使用公式计算：Delta E-n = [(Delta L-n + (Delta a(n))(2)+ (Delta b(n))(2)]（1/2）结果。经ANOVA和Tukey的检验，蒸馏水没有引起明显的颜色变化。表面处理对染色的影响无统计学意义（P < 0.05）。FSS与污渍或材料之间没有很强的相互作用。表面与材料、染色剂与材料之间存在较强的相互作用（P < 0.001）。所有材料都容易被各种污渍染色，尤其是咖啡、红酒和茶；富士9号的敏感性最低，F2000的敏感性最高。(c) 2004 Elsevier Ltd.版权所有。
Objectives. To determine the degree of surface staining of resin-based composites (RBCs) and glass-ionomer cements (GICs) after immersion in various stains and food-simulating solutions (FSS).Methods. Six tooth-coloured restorative materials were used: a light-cured microfilled RBC (Durafil, Kulzer), a light-cured microglass RBC (Charisma, Kulzer), a potyacid-modified RBC (F2000, 3M/ESPE), a conventional GIC (Fuji IX, GC) and two resin-modified GICs (Fuji 11 LC, GC; Photac Fit, 3M/ESPE). Disk-shaped specimens were prepared and tested with either a matrix finish or polished using wet silicon carbide papers up to 2000 grit. All. specimens were immersed in 37 degrees C distilled water for 1 week, followed by three different FSS (water, 10% ethanol, Crodamol GTCC) and five stains (red wine, coffee, tea, soy sauce and cola) for a further 2 weeks. Three specimens of each material for each stain were tested. Colour coefficients (CIE L* a* b*) were measured by a spectrophotometer after each treatment. The change in colour (Delta E-n) was calculated using the formula: Delta E-n = [(Delta L-n + (Delta a(n))(2)+ (Delta b(n))(2)](1/2)Results. Distilled water caused no perceptible colour change as tested by ANOVA and Tukey's tests. The effect of surface finish on staining was not statistically significant (P > 0.05). There was no strong interaction between FSS and stains or between FSS and materials. There was a strong interaction between surface and material, and stain and material (P < 0.001).Conclusions. All materials were susceptible to staining by all stains especially coffee, red wine and tea; Fuji IX showed the least susceptibility and F2000 the greatest. (c) 2004 Elsevier Ltd.
