Resumo
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.
