Abstract
Objective: To evaluate the effects of chemical disinfection methods on the color stability of maxillofacial silicone. Methods: An integrative literature review was conducted in the PubMed and CAPES databases, using the descriptors "Maxillofacial Prosthesis", "Silicone", "Color Stability", and "Disinfection", including publications from the last six years (2020-2025). After applying the inclusion and exclusion criteria, six in vitro studies were selected for analysis. Results: The results showed that neutral and antibacterial soap caused greater color degradation of the silicone material, while 2% chlorhexidine presented a better balance between antimicrobial efficacy and color stability. Phytotherapeutic agents, such as Thymus vulgaris and Mangifera indica, showed promise due to their antioxidant and biocompatible properties, reducing pigment degradation. In addition, the incorporation of nanoparticles, such as titanium dioxide and silver, increased the material's resistance to discoloration. Final considerations: It is concluded that the choice of disinfection method is essential for the color stability of silicone prostheses, and in vivo clinical studies are needed to support standardized and safe protocols for the prolonged use of maxillofacial prostheses.
