摘要
材料和方法:来自德累斯顿、莱比锡、柏林、奥洛穆克和格雷夫斯瓦尔德大学的牙科学生(N=37)参与了本研究。一个标准化的讲座，然后是基于网络的牙齿指导-训练器工具(www.toothguide.de)，为学生准备与计算机辅助的“牙齿指导-训练盒”(TTB, VITA Zahnfabrik)相匹配的模板。参与者在中性灰色环境(参考)中进行配色后，在修改后的ttb(红、黄、蓝)上重复配色。计算与所选模板的颜色距离(∆E)，并将性别和年龄混淆。采用Mann-WhitneyU检验计算均数和标准差(SD)、中位数和95%置信区间(95% CI) (α= 0.05)。
Influence of Surrounding Conditions on Visual Determination of Tooth Shade
Material and methods: Dental students (N=37) at the Universities in Dresden, Leipzig, Berlin, Olomuc and Greifswald participated in this research. A standardized lecture, followed by the web-based Toothguide-Trainer tool (www.toothguide.de) prepares the students for templates matching with the computer aided “Tooth guide-Training-Box” (TTB, VITA Zahnfabrik).After color matching in neutral grey surrounding (reference), the participants repeated the matching on modified TTBs (red, yellow and blue). Color distance to the selected templates (∆E) was calculated confounded by gender and age. The mean and standard deviation (SD), median and the 95 % confidence interval (95% CI) were calculated using Mann-WhitneyU test (α=.05).
