Abstract

Accurate and predictable shade matching for dental restorations can be a challenge for dentists and dental technicians. Visual color matching using shade guides is still the most commonly used method, but this method remained a skill acquired through clinical experience. The seemingly simple method of comparing and matching the color of shade tabs with the color of teeth often leads to mistakes that range from minor to severe mismatches. The main goal of this study was to evaluate the shade matching ability of dental students as they progress through their education. Dental students (N=174), divided into experimental and control groups, matched the color of eight shade tabs colors under standardized lighting conditions, using viewing booth, and hand-held shade matching unit. The experimental group attended the lecture on color and appearance in dentistry and completed Dental Color Matcher, an online education and training program. The control group did not have any additional information in between two shade matching sessions. The score for the best match (the match with the smallest color difference) was 10 points, the 2nd best match 9 points and so on up to 1 point if the 10th best match was selected. Means and standard deviations were calculated using two CIE color difference formulae, CIELAB and CIEDE2000. Differences were analyzed using the Student t-test, ANOVA and ANCOVA test. The experimental group achieved a statistically significant improvement in the after shade matching session on overall results, on different shade tabs and on all colors separately. The control group (with no color education and training) did not improve shade matching scores in the second session. No significant differences were found between genders in this study. The main conclusion was that education has crucial role in improvement of shade matching skills.
