The aim of this research is to compare the fluorescence of different trademarks of composite resins under ultraviolet light, indicating through the optical characteristics the restorative materials that best mimic the properties of dental fluorescence. In this study, nine composite resin trademarks of EA2 color were evaluated, and ten test samples were prepared for each material, totalizing ninety specimens. The specimens were produced from a bipartite aluminium matrix (10×2 mm), and then stored for 24 h in tubes of radiographic films, immersed in distilled water and after 48 h it were polished. A blind-type study (four evaluators) was used and the samples were analyzed in a dark wooden chamber where it was coupled two black lamps. In the data collection phase, the Kolmogorov-Smirnov normality test, ANOVA and Post Hoc of Tukey were used (adopting a significance level of 0.05). It was noted that the composite resin of the trademark Ultrafill was more fluorescent and Luna was statistically less fluorescent than all other materials, while Opallis and Tetric were superior to Glacier. There was no significant statistical difference among the composite resins Premissa, Point 4, Llis and Premium.
