Abstract in Portuguese
O objetivo deste estudo foi o de avaliar a estabilidade de cor de diferentes cores de cimento (transparente, claro, e escuro) polimerizados de forma foto (Choice 2 Bisco, Rely X Veneer - 3M ESPE) ou dual (Variolink II Ivoclar-Vivadent, All Cem FGM). Um espectrofotômetro (Easyshade - VITA) foi usado para medir a cor das amostras (n=6) imediatamente após a confecção do espécime, 7 dias, 30 dias e 90 dias após. Os valores médios de diferença de cor (ΔE) foram maiores para as cores transparente (ΔE = 4,41), seguido pelas cores claras (ΔE = 3,12) e escuras (ΔE = 3,25). Os valores médios de ΔE foram menores para os cimentos fotoativados (Choice 2 ΔE = 2,79; Rely X VeneerΔE = 3,49) em comparação com os cimentos duais (Variolink II ΔE = 3,60; All Cem ΔE = 4,48). Um aumento dos valores ΔE foram observados com o aumento dos períodos de tempo avaliados (7 dias ΔE = 2,79; 30 dias ΔE = 3,73; 90 dias ΔE = 4,25).

Abstract in English
The aim of this study was to evaluate the color stability of different cement color (transparent, clear, and dark) of light-polymerized resin cement (Choice 2 - Bisco, Rely X Veneer - 3M ESPE) or dual-cured cement (Variolink II Ivoclar- Vivadent , All Cem - FGM). Spectrophotometer (Easyshade - VITA) was used to measure the color of samples (n = 6) immediately after preparation, 7 days, 30 days and 90 days. The mean color difference (ΔE) was higher for transparent colors (ΔE = 4,41), followed by light (ΔE = 3,12) and dark colors (ΔE = 3,25). The mean values of ΔE were lower for the light-polymerized resin cement (Choice 2 ΔE = 2,79; Rely X Veneer ΔE = 3,49) compared to the dual-cured cement (Variolink II ΔE = 3,60; All Cem ΔE = 4,48). An increase in ΔE values was observed with increasing periods of time (7 days ΔE = 2,79; 30 days ΔE = 3,73; 90 days ΔE = 4,25).
