Effect of titanium dioxide nanocoating on the colour stability of room temperature vulcanizing maxillofacial silicone —an invitro study

ConclusionsThe colour change that occurred in titanium dioxide nanocoated specimens following accelerated ageing was significantly lower than that in the uncoated group, showing that the TiO2 nanocoating was effective in reducing the colour degradation of silicone elastomers.Clinical relevanceMaxillofacial prostheses fabricated from silicone elastomers go through undesirable colour degradation over time. The development of a scientific technique that retards the colour deterioration of silicone prostheses would be of great clinical significance.
