Abstract

The preservation of color stability in maxillofacial silicone prostheses is essential for their aesthetic appeal and functional durability. This research investigated the impact of two soap-based disinfectants and tap water on the color stability of three silicone elastomers: A-2186-F, VST-50, and GC Silfy, over a simulated five-year clinical service duration. The samples were immersed daily for two weeks in tap water, Muse hand disinfectant soap, and Hadakara body soap, simulating approximately five years of clinical use. Color stability was evaluated at baseline (T₀), after 7 days (T₁), and after 14 days (T₂). The results revealed that the disinfectants exerted minimal influence on the color stability of the silicones, with GC Silfy and VST-50 exhibiting greater resistance to discoloration than A-2186-F. Particularly, exposure to Muse hand disinfectant soap led to the most significant color alteration in A-2186-F. Nevertheless, the changes observed across all materials remained below the threshold of perceptibility (ΔE∗ = 1.1), indicating that they are not visually noticeable. These findings underscore the significance of selecting appropriate materials and ensuring disinfectant compatibility to preserve the aesthetic quality of maxillofacial prostheses. By refining cleaning protocols, it may be feasible to improve the longevity and clinical efficacy of these prosthetic materials.

期刊介绍： Dyes and Pigments covers the scientific and technical aspects of the chemistry and physics of dyes, pigments and their intermediates. Emphasis is placed on the properties of the colouring matters themselves rather than on their applications or the system in which they may be applied. Thus the journal accepts research and review papers on the synthesis of dyes, pigments and intermediates, their physical or chemical properties, e.g. spectroscopic, surface, solution or solid state characteristics, the physical aspects of their preparation, e.g. precipitation, nucleation and growth, crystal formation, liquid crystalline characteristics, their photochemical, ecological or biological properties and the relationship between colour and chemical constitution. However, papers are considered which deal with the more fundamental aspects of colourant application and of the interactions of colourants with substrates or media. The journal will interest a wide variety of workers in a range of disciplines whose work involves dyes, pigments and their intermediates, and provides a platform for investigators with common interests but diverse fields of activity such as cosmetics, reprographics, dye and pigment synthesis, medical research, polymers, etc.
