BACKGROUND
During its clinical practice, the dentist is often faced with issues concerning the determination of teeth shade. This step is considered sensitive by numerous clinicians and dental laboratories. The objective of this study was to test the ability of professional dentists to visually determine the teeth color.
MATERIAL AND METHODS
Eleven dentists classified 35 unmarked samples according to their hue, chroma and value from 2 standardized tooth shade guides Ivoclar-Vivadent (Chromascop) et Vita (3D Master). The ratio between the number of matching samples and the total amount of samples from each group was calculated and converted to a score between 0 and 10.
RESULTS
Better scores were obtained for value and chroma with the 3D Master shade guide than with the Chromascop shade guide (p < 0.001). The opposite result was obtained for the hue (p < 0.05). Globally, better results were obtained for the value and chroma, the hue being the most difficult item to evaluate. A satisfying "color perception" was observed in 69% of the cases.
CONCLUSION
The results of this study argue in favor of a specific training for tooth shade determination in Odontology.
背景
在临床实践中，牙医常常面临牙齿颜色测定的问题。许多临床医生和牙科实验室认为这一步骤较为敏感。本研究的目的是测试专业牙医视觉判定牙齿颜色的能力。
材料与方法
11名牙医根据来自2种标准化牙齿比色板（义获嘉威瓦登特公司的Chromascop和维他公司的3D Master）的色调、彩度和明度对35个未标记样本进行分类。计算每组匹配样本数量与样本总量的比例，并将其转换为0至10分的分数。
结果
使用3D Master比色板在明度和彩度方面获得的分数高于Chromascop比色板（p < 0.001）。在色调方面则得到相反结果（p < 0.05）。总体而言，明度和彩度方面得到的结果更好，色调是最难评估的项目。在69%的案例中观察到了令人满意的“颜色感知”。
结论
本研究结果支持在牙科学中针对牙齿颜色测定进行特定培训。
