A previous paper reported the construction of a tooth colour atlas. This was used to carry out an extensive measurement and classification of tooth colour. The distribution data obtained showed that 80 percent of tooth colour was concentrated in a central hue band of tooth colour space. Utilising the "blending effect" of composite resin restorations the colour samples could be restricted to this narrow band. A modification of the tooth colour atlas producing a simplified nine colour guide for composite resins was proposed and theoretically this new colour system would achieve approximately ninety-five percent undetectable colour matching. This paper explains the development of the colour guide and reports on two clinical trials to determine the validity of the theoretical conclusions.
先前的一篇论文报道了牙齿颜色图谱的构建。该图谱用于对牙齿颜色进行广泛的测量和分类。所获得的分布数据表明，80%的牙齿颜色集中在牙齿颜色空间的一个中心色调带内。利用复合树脂修复体的“混合效应”，颜色样本可以限制在这个窄带内。提出了对牙齿颜色图谱的一种改进，产生了一种简化的复合树脂九色指南，从理论上讲，这个新的颜色系统将实现约95%的不可察觉的颜色匹配。本文解释了颜色指南的开发过程，并报告了两项临床试验，以确定理论结论的有效性。
