Malden: Wiley-blackwell, v. 18, n. 3, p. 242-244, 2009.1059-941Xhttp://hdl.handle.net/11449/15341Purpose: 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.242-244engMaxillofacial prosthesispigmentationchemical disinfectionArtigo10.1111/j.1532-849X.2008.00411.xWOS:000207914300007Acesso restrito971988381487258289428048190763920000-0002-3800-30500000-0003-1781-1953
