Abstract

Objective: To quantitatively determine in 7 different commercial brands of composite resins that mimic dentin (Filtek Z350XT® 3M ESPE™, Miris 2® Coltène™, Empress Direct® Ivoclar Vivadent™, Opallis® FGM™, TPH Spectra® DentsplySirona™ Tetric N Ceram® Ivoclar Vivadent™, Brilliant Everglow® Coltène™) coded as Vita Clásica Vita Zahnfabrik™’s A2 and A3 or an equivalent dye, the difference in color (ΔE) with the Vita Classic scale for that codification on a black or white background.

Materials and methods: In vitro descriptive study. 7 composite resin brands (N 35) in A3 and A2 tones were used, 10 mm diameter and 2 mm thick discs were made, measured with spectrophotometry on two backgrounds with Vita Easyshade V® Vita Zahnfabrik ™ instrument. The values obtained in CIELAB were analyzed obtaining ΔE. An ANOVA 2 factor test (a0.05) was performed.

Results: The ΔE closest to the Vita Classic® scale was given by TPH Spectra® DentsplySirona ™ A2 (1.02 ± .69), the largest ΔE was Filtek Z350XT® 3M ESPE ™ (69.31 ± .50).

Conclusion: There are clear differences between composite resins of the studied brands and the Vita Classical scale. On a black background 71.4% of all samples and on a white background 92.8% are on a ΔE 5, meaning that the differences between their dyes are considered clinically unacceptable. None of the composite resin brands meet the colorimetric characteristics when compared to the Vita Classic scale.
