Clinical Impact of Targeted Short-Term Color Science Training on Shade Matching Accuracy of Light-Colored Teeth

This study aimed to assess the effect of targeted short-term color science training on the accuracy of shade matching of light-colored teeth.

Fifty dental providers from the University of Florida College of Dentistry participated in this study. Participants were divided into two groups: (1) a control group that received no additional training and (2) a test group that underwent specific color science training. All participants were asked to select the shade of the left maxillary central incisor of five patients with light-colored teeth using the VITA Linearguide 3D Master shade guide across two sessions held 2 weeks apart. Shade matching accuracy was measured by comparing the participants' selected shades to those obtained by the Vita Easyshade spectrophotometer, with differences calculated using the CIEDE2000 formula. Results were analyzed using ANOVA, with statistical significance set at p < 0.05 and a 95% confidence interval.

The results of the ANOVA revealed no significant difference between the test and control groups for either ΔE (F statistic: 0.042, p-value: 0.837), ΔL (F statistic: 0.038, p-value: 0.846), Δb (F statistic: 0.078, p-value: 0.780), or Δa (F statistic: 0.111, p-value: 0.740).

This study found that short, targeted training did not significantly improve providers' shade-matching accuracy for challenging cases such as light-colored teeth. Future studies should explore the impact of extended, multi-session training programs incorporating hands-on practice, enabling participants to refine their shade-matching skills through repeated, practical application.

Training protocols integrating color theory lectures, hands-on exercises, and clinical practice on diverse cases could better prepare providers to address the nuanced demands of shade selection for light-colored teeth.
