RESUMO

This study investigated the perception of color difference among distinct group of dental personnel and the influence of each color coordinate on the perception of color difference. The color vision deficiency was the only exclusion criteria used. Screening for color defective vision was conducted using the simplified version of Ishihara test. Two men who missed 1 or more plates did not take part in this study. Fifty one subjects took part in this experiment: 20 final year dental students, 20 dental practitioners and 11 teachers. All visual assessments were conducted with D65 illumination of visual observation booth. Test was composed of 1 standard card and 3 sets of cards. Each set consisted of 1 card that did not differ from standard card and 6 cards that differed from the standard card in only one coordinate L*, a* or b*. The subjects were asked to select: 1 card that matched to the standard card; 1 card that color difference from the standard card would be acceptable; and 1 card that color difference from the standard card would be unacceptable. The analysis of percentis suggests that within the limitations of this study: there were no significant difference in color difference perception between men and women or between dental students, dental practitioners and teachers.
