Brief Summary

Visual shade matching (VSM) is the most common procedure to select an adequate shade in dentistry. This clinical procedure requires the use of a shade guide, being Vita Classical (VC) the most popular among the available guides. VSM is a subjective and inconsistent process with many observer related variables (e.g. color deficiency, experience, gender and eye fatigue) that can influence on the final color appearance. The gender influence on the accuracy of VSM is controversial. The purpose of this study is to evaluate the VSM performed by female (F) and male (M) students, using VC shade guide, testing the null hypothesis that VSM is not influenced by gender.
