摘要： 目的:研究不同牙釉质/牙本质树脂配色方案对复合树脂双层修复颜色效果的影响。方法:选择2个品牌(Z350,NG)按照牙釉质色与牙本质色一致(方案1),牙本质色比牙釉质色加深一个色号(方案2),牙釉质色统一为A3色(方案3)3种配色方案制作釉质层1.0 mm厚双层修复树脂试样,分光光谱仪测量获取试样颜色参数并计算与Vita经典比色板的色差(ΔE)。结果:2种树脂品牌及3种配色方案的ΔE值均有统计学差异(P<0.05)。Z350的ΔE值均小于NG。对于A1色,方案一的△E值最小;对于A2色,方案1、2的ΔE值小于方案3。结论:对于釉质层1.0 mm厚的树脂双层修复,Z350颜色与比色板颜色更接近;对于A1色,牙釉质色与牙本质色一致的传统配色方案与A1色比色板颜色最接近;对于A2色,传统方案与牙本质色比牙釉质色深一个色号的配色方案与A2色比色板颜色更接近。

Abstract: Objective: To investigate the effects of different enamel/dentin composite shade matching methods on the resultant color of double-layered resin composite restorations. Methods: Two commercial resin composites (Z350 & NG) were included in this study. Resin specimens of each brand were prepared following 3 double-layered color matching methods:(1) dentin shade and enamel shade with the same shade but different translucencies; (2) dentin shade was darker than enamel shade; (3) enamel shade with A3 shade. The color coordinates of all the specimens and the corresponding Vita Classical Shade tabs were measured by a spectrophotometer. Color differences (ΔE) between the specimens and the corresponding Vita Classical Shade tabs were calculated. Results: There were significant differences between two commercial resin composites (P<0.05). ΔE values of Z350 were significantly lower than those of NG. Regarding to A1 shade, method 1 had the lowest ΔE value. With respect to A2 shade, the ΔE values of method 1 and 2 were lower than method 3. Conclusion: Z350 performs better results in matching the shade guide in contrast to NG. Method 1 is the best enamel/dentin composite shade matching methods for A1 shade. For A2 shade, method 1 and method 2 are better than method 3.
