Abstract: Color stability of resin and silicone is an important factor for longevity of facial prostheses. The aim of this study was to evaluate the color stability of resins and silicone for facial prostheses. Three brands of acrylic resin and I of facial silicone were evaluated considering pigment incorporation for the colorless materials. Ten samples of each material were fabricated and submitted to measurements of chromatic alteration initially and after 252, 504, and 1008 hours of weathering through Visual analysis and spectrophotometry. Data were evaluated by analysis of variance and Tukey test (P < 0.05). Results showed a statistically significant difference in color alteration among materials independent of aging. According to visual analysis, the color difference between pigmented and colorless Silastic MDX4-4210 and between pigmented and colorless Classico acrylic resin was statistically significant for the 3 weathering periods. Aging for 1008 hours represented a significant influence on color alteration of all resins. All materials presented chromatic alteration after accelerated artificial aging.
