Purpose: The purpose of this study was to evaluate the color stability of two silicones for use in facial prostheses, under the influence of chemical disinfection and storage time. Materials and Methods: Twenty‐eight specimens were obtained half made from Silastic MDX 4‐4210 silicone and the other half from Silastic 732 RTV silicone. The specimens were divided into four groups: Silastic 732 RTV and MDX 4‐4210 with disinfection three times a week with Efferdent and Sliastic 732 RTV and MDX 4‐4210 disinfected with neutral soap. Color stability was analyzed by spectrophotometry, immediately and 2 months after making the specimens. After obtaining the results, ANOVA and Tukey test with 1% reliability were used for statistical analysis. Results: Statistical differences between mean color values were observed. Disinfection with Efferdent did not statistically influence the mean color values. Conclusion: The factors of storage time and disinfection statistically influenced color stability; disinfection acts as a bleaching agent in silicone materials.
