Accurate shade analysis and communication represent one of the biggest challenges in restorative and esthetic dentistry today, especially in light of the rapidly increasing array of ceramic materials available. Traditional methods of shade analysis have relied upon the use of conventional shade guides or, more recently, digital shade measurement. In this article, the author examines the advantages and disadvantages of traditional shade analysis; reviews principles for optimizing the evaluation process, including information regarding the scientific basis of general color science, optics, and aspects of material science; and proposes a six-step approach to shade analysis in which less emphasis is placed on shade guide samples in favor of natural internal structures and surface properties and their replication in different dentin, enamel, transparent, and colored translucent, as well as fluorescent and opalescent, ceramics.
准确的比色分析和沟通是当今修复和美容牙科领域面临的最大挑战之一，尤其是考虑到可用陶瓷材料的种类迅速增加。传统的比色分析方法依赖于使用传统比色板，或者最近依赖于数字比色测量。在本文中，作者研究了传统比色分析的优缺点；回顾了优化评估过程的原则，包括有关一般颜色科学、光学和材料科学方面的科学基础的信息；并提出了一种比色分析的六步法，其中较少强调比色板样本，而是更注重天然内部结构和表面特性，以及它们在不同的牙本质、牙釉质、透明、彩色半透明以及荧光和乳光陶瓷中的复制。
