摘　　要：目的比较常规银汞合金充填、银汞合金粘接充填、瓷化树脂充填磨牙邻面Ⅱ类洞的临床效果。方法将350例465颗邻面Ⅱ类洞的磨牙随机分为A、B、C 3组,分别采用常规银汞合金充填、银汞合金粘接充填和瓷化树脂充填,修复后1、3年进行复查。结果 A组、B组和C组1年后充填成功率分别为98.00%、100.00%、100.00%,3年后成功率分别为71.33%、85.71%、97.32%。3年后在密合度方面,B组优于A组(χ2=6.02,P=0.014),C组优于A组(χ2=19.98,P=0.000)和B组(χ2=5.19,P=0.026);牙髓炎发生率,A组高于B组(χ2=4.50,P=0.034)和C组(χ2=7.12,P=0.015),差异有统计学意义;充填体破损率,A组高于C组(χ2=8.17,P=0.007),B组高于C组(χ2=7.27,P=0.007),差异有统计学意义。结论瓷化树脂用于磨牙邻面Ⅱ类洞的充填效果最佳,银汞合金粘接充填优于常规银汞合金充填。Objective To compare the restoration effect of silver amalgam filling,bonded amalgam restoration and tetric ceram filling for treatment of proximal-occlusal cavity in molars.Methods Four hundred and sixty-five malors from 350 cases were randomized into 3 groups,and treated with 3 kinds of restoration methods,which were silver amalgam filling,bonded amalgam restoration and tetric ceram filling.Results The periodical follow-up in the first year revealed no difference in the restoration effect of 3 groups,and the success rates were 98.00%,100.00%,100.00% respectively.There was significant difference among these groups after three years,and the success rates were 71.33%,85.71%,97.32% respectively.The tetric ceram filling group was better than bonded amalgam restoration group,and the bonded amalgam restoration group was better than silver amalgam filling group.Conclusion Tetric ceram filling shows the best restoration effect,more suitable than other two methods,and the bonded amalgam restoration is better than silver amalgam filling.
