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），并考察了其在模拟佩戴硅酮唇部假体（silicone lip prosthesis）的患者日常饮用热饮的条件下的颜色变化情况。结果观察到，上述硅酮假体在接触本次试验所用饮品后，整体出现了颜色变化。
