摘　　要：目的 研究新型不含汞的牙体充填材料镓合金的抗腐蚀性能。方法 运用电化学方法,以高铜银汞合金为参照,检测镓合金在人工唾液中的电化学腐蚀速度。结果 在人工唾液中镓合金与高铜银汞合金的腐蚀速度无显著性差异(P>0.05)。结论 镓合金在人工唾液中具有良好的抗腐蚀性能。Objective The objective of this study was to test the corrosion resistance of Gallium alloy,a new mercury-free dental restorative material. Methods The electrochemical method was used in the present study to investigate the rate of electrochemical corrosion of gallium alloy in artificial saliva, using a high-copper amalgam as control. Results The results indicated that there was no significant difference between the rates of electrochemical corrosion of the two alloys (P>0. 05). Conclusions The corrosion resistance of gallium alloys as well as that of high-copper amalgam was considerably good in artifcial saliva.
