摘要
本文比较了镓合金与银汞合金两种牙体修复材料的耐磨性、腐蚀性及菌斑附着情况。探讨镓合金在临床上被选用的可能性。体外实验的结果显示，银汞合金的耐磨性和耐腐蚀性均优于镓合金，并有显著性差异。银汞合金充填体的菌斑指数及菌落计数均低于镓合金充填体，也有高度显著性差异。
The adhesion of plaque on dental restorative between gallium alloy and amal-gam alloy were compared. The results showed that plaque index and plaque account of gallium alloy was higher than those of amalgam, there was statistically significance(p<0.01). It was possible that secondary caries of gallium alloy's restorative may be higher than those of amal-gam. On the other hand,the surface of restorative polished was necessary to improve the adhe-sion of plaque and to prevent the secondary caries.
