The aim of this study was investigate the optical density of four different brands of composite resins of nanotechnology. The composite resins Estelite Sigma Quick® (Tokuyama), Esthet –X HD® (Dentsply), 4 Seasons® (Ivoclar Vivadent) and Filtek Z350XTTM (3M-ESPE) were inserted into cavities in transparent acrylic sheets, separated by thickness into 1, 2 and 3 mm. The images were imported into the software ImageTool® 3.0 (UTHSCSA, EUA). Data were submitted to ANOVA and Tukey. The mean values of the composite resins 4 Seasons® (2.71±0.20) and Filtek Z350XTTM (2.64±0.26) did not differ statistically for samples with thickness of 1 and 2 mm. However, for both thickness Estelite Sigma Quick® (1.92±0.11) and Esthet-X HD® (3.57±0.29) showed significant differences compared to the other composite resins (p = .012). All 3 mm-thick samples showed significant differences among themselves (Estelite Sigma Quick® p < .001, Esthet-X HD® p < .001, 4 Seasons® p=.001 and Filtek Z350XTTMp = .003). Conclusion: Among the three thicknesses evaluated, Estelite Sigma Quick® showed the lowest optical density, whereas the highest values were observed for Esthet X HD®. The resins are studied according to the rules of optical density value thus being favorable clinical use.
