The aim of this study was to identify color visiondeficient individuals, testing visual acuity in a dental student group and comparing the obtained result with those found in literature, considering the damage of congenital dyschromatopsia to Dentistry, specially to tooth color matching. Six determined plates were chosen from the plate sequence of the Ishihara Test, and they were presented as six slides to 308 dental students. During the presentation, the individuals filled out a form with their personal information and the reading of the plate they saw. The Ishihara Test is a reading test of pseudoisochromatic plates used to identify individuals with congenital dyschromatopsia, and it is the most widely used test for this purpose. Three hundred and eight individuals were evaluated. From these, 121 (39.3%) were men and 187 (60.7%) were women, with ages between 19 and 37 years. From the total, 13 (4.2%) were considered color vision-deficient; 8 (6.6%) were men and 5 (2.6%) were women. After statistical analysis, we could affirm that, with 95% of probability, the real proportion of color vision-deficient men ranges from 3.14% to 12.16%; and the real proportion of color visiondeficient women ranges from 0.96% to 5.68%. We rejected the hypothesis that our female population agrees with that found in literature. On the other hand, our male population seems to agree with that found in literature.
