Abstract

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 Z350XT^TM (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 Z350XT^TM (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 Z350XT^TMp = .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.
