Abstract
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).
