Evaluation of the color stability of three maxillofacial silicone materials after exposure to beverages

We compared 3 non-pigmented silicone elastomers and color changes under conditions simulating the regular consumption of hot beverage by a patient wearing a silicone lip prosthesis. It was observed that there was overall color change of these silicone prostheses after exposure exposed to the tested beverages.本研究对比了3种无色素硅酮弹性体（silicone elastomers），并在模拟佩戴硅酮唇部假体（silicone lip prosthesis）的患者常规饮用热饮的条件下，观察其色泽变化。经观察发现，上述硅酮假体在接触受试饮品后，整体均出现了色泽变化。
