通常，在牙科学中，比色原则的根据是1898年美国画家Albert Henry Munsell的理论，Clark于1930年把Munsell的理论应用到牙科学中。根据这一理论，色彩由三个维度组成：色调，色度和明度。

In general, in dentistry, the principle of colorimetry is based on the theory of Albert Henry Munsell, an American painter in 1898, and Clark applied the theory of Munsell to dental science in 1930. According to this theory, color consists of three dimensions: hue, color and lightness.

 色调是牙齿的基本色彩，色度是色调的饱和程度，明度代表亮度。标准VITA 比色板有四个基本色调(A,B,C和D)，每一色调有四个色度。

The tone is the basic color of the teeth, the color is the saturation of the tone, and the brightness represents the brightness. The standard VITA color palette has four basic colors (A, B, C and D), and each shade has four chromaticity.

实际上，牙齿的色彩是很多因素相互作用的综合结果，在对光波的折射与反射过程中，牙釉质和牙本质与光相互作用。在牙釉质区，接近白-蓝光的短波光占优势，而在牙本质，波长较长的黄-橙光则更为明显。

In fact, the color of the teeth is a comprehensive result of the interaction of many factors. In the process of refraction and reflection of the light waves, the enamel and dentin interact with the light. In the enamel area, the short wave light near white blue light dominates, while in the dentin, the longer the yellow orange light is, the more obvious.

牙色是几种因素的综合结果，必须认真分析这些因素，才能了解每位患者牙齿的独特特征，传统的方法不够精确，因此无法实现这一点。

Tooth color is a comprehensive result of several factors. It is necessary to carefully analyze these factors to understand the unique characteristics of each patient's teeth. The traditional method is not accurate enough, so it can not be realized.

 要确定牙色，就必须抛却传统的比色板，而采用具有更高牙色分析能力的个性化色彩分析理论：瓦尼尼医生的色彩理论。我们通常看到的牙色是牙本质和牙釉质的物理特征及其与光相互作用的结果。

To determine the color of the tooth, it is necessary to throw away the traditional colorimetric plate and adopt the individualized color analysis theory with higher tooth color analysis: the color theory of Dr. watnei. The tooth color we usually see is the physical characteristics of dentin and enamel and its interaction with light.

瓦尼尼的牙色理论包括对与牙色相关的每一因素的详细分析。用一种特殊的色彩表格记录每一因素。然后在分层填充阶段使用特定的材料重现这些因素。

Vanini's theory of tooth color includes detailed analysis of every factor related to tooth color. Record each factor in a special color form. These factors are then reproduced in a stratified filling stage using specific materials.

要想正确确定牙色，牙医必须能够看到牙齿结构的深层，确定五个色彩维度和色带。要做到这些，我们需要一种色温恒定在5500开尔文的光，有几个研究表明这种光是评估色彩的理想的光，然后，采用数字摄影技术分析色维度，因为数字摄影技术能够让我们利用计算机对牙齿做更深的检查，更精确地判断不同的色维度。图片曝光不足和增加对比度更有助于更好地看清色维度，增加切端光泽的琥珀色和蓝色色调。

To correctly determine the color of a tooth, the dentist must be able to see the depth of the tooth structure and determine the five color dimensions and ribbons. To do this, we need a color temperature constant at 5500 Kelvin. Several studies have shown that this light is the ideal light to evaluate color, and then, using digital photography to analyze the color dimension, because digital photography allows us to make a deeper examination of the teeth with a computer and judge the difference more accurately. Color dimension. Insufficient exposure and increased contrast can help to better see the color dimension and increase the amber and blue tones of the end gloss.

 所有的牙齿色彩信息必须以简单的方式记录下来，为此我们设计了一个特殊的色图表，用于研究和确定五种色维度和获得这些效果需要的特定材料。色图表代表修复方案，争取实现色图表的方案才能获得满意的修复效果。表的前面列出了患者的详细信息，还包括两个蓝色牙色区。左边是五种色维度，右侧是重现色彩所需的复合树脂材料(也就是牙釉质，牙本质复合树脂)的首字母。

All tooth color information must be recorded in a simple way. To this end, we have designed a special color chart for the study and determination of five color dimensions and the specific materials needed to obtain these effects. The color chart represents the restoration plan and strives to achieve a satisfactory repair effect by achieving the color chart. The details of the patient are listed in the table, and two blue tooth areas are included. On the left, there are five color dimensions, and the right is the first letter of the composite resin material (that is, enamel, dentin composite resin).
