摘要
目的 :探讨修复根面龋较理想的材料。方法 :选择 1 92颗根面龋患牙 ,分别采用银汞合金、光固化复合树脂和银粉玻璃离子充填修复。随访观察 2年。结果 :三种材料修复成功率分别为 5 3 2 3% ,75 86 %和 88 89%。银汞合金与光固化复合树脂两种材料修复成功率有显著性差异 (P <0 0 1 ) ;银汞合金与银粉玻璃离子两种材料修复成功率有显著性差异 (P <0 0 1 ) ;银粉玻璃离子与光固化复合树脂两种材料修复成功有显著性差异 (P <0 0 5 )。结论 :银粉玻璃离子是修复根面龋较为理想的材料 。
Objective:To evaluate the effects of three kinds of materials on the treatment of root caries.Methods:One hundred and ninety two teeth with root caries were divided into three groups randomly,and filled separately with silver amalgam?light cured composite and glass ionomer silver reinforced restorative with follow up of two years.Results:The success rate in group of silver amalgam was 53 23%,group of ligh cured composite 75 86% and group glass ionomer silver reinforced restorative 88 89%.There were significant difference among the three groups:group silver amalgam compared with group light cured composite ( P <0 01);group silver amalgam compared with group glass ionomer silver reinforced restorative ( P <0 01);group light cured composite compared with group glass ionomer silver reinforced restorative ( P <0 05).Conclusion:The glass ionomer silver reinforced restorative works better than silver annalgam and light cured compsite and is a ideal filling material for root caries.
