Resumo: Objective. To evaluate the color stability of a facial prosthesis elastomer at different times of institution of disinfection protocols. Study Design. Seven experimental groups (n=15/group) were evaluated after immersion in distilled water (Control, C); nanochlorhexidine (NC); and chlorhexidine digluconate (DC) at different concentrations [0.12% (DC0.12%); 1% (DC1%); 2% (DC2%)] and DC associated with surfactants at 2% (DC+S2%) and 4% (DC+S4%). Color stability measurements (CieLab formula and National Standard Bureau, NBS) were performed at baseline, 1, 3, 6, 9 and 12 simulated months of disinfection. Data was processed by Kruskal Wallis and Dunn (p≤0,05). Results. After 1 month, DC1% and DC2% were similar and caused the least color changes (p≤0.01). All solutions equalized after 3 months, with the exception of DC2%. After 6 months, NC was equal to the control (NBS: mild) and showed the smallest color changes (p≤0.044), remaining so for up to 12 months. DC+S4% showed the greatest color changes after 6 and 9 months (NBS: appreciable). Conclusion. In the end, Nanochlorhexidine and chlorhexidine digluconate at 0.12% caused the lowest color changes. The chlorhexidine digluconate at 4% associated with surfactants obtained the worst findings.
