老年人根面龋3种材料修复的疗效分析

The analysis of curative effect among three kinds of materials in the restoration of senile persons with root caries

目的:探讨修复老年人根面龋较理想的材料。方法:将216颗根面龋患牙,分别采用Dyract复合体、光固化复合树脂和玻璃离子水门汀充填修复。随访观察1-2年。结果:观察1年,3种材料修复成功率有显著性差异,Dyract复合体成功率(96.2%)最高;观察2年,Dyract复合体成功率94.9%,明显高于玻璃离子水门汀的成功率77.9%(P<0.01)和光固化复合树脂的成功率61.4%(P<0.01),差异均具有显著性。结论:Dyract复合体是修复根面龋较为理想的材料。

Objective： To discuss ideal material on the treatment of senile persons with root caries. Methods： 216 teeth with root caries were filled separately with Dyract complex and light-cured composite resin and glass ionomer cement. The fillings were followed up for one-two years. Results： After one year, there were significant difference among the three kinds of materials. The filling success rate of Dyract complex （96.2%） was highest; After two years, the success rate of Dyract Was 94.9%,which was significantly higher than 77.9% of glass ionomer cement （P〈 0.0 1） and 61.4% of light-cured composite resin （P〈 0.01）, the difference was conspicuous. Conclusion： Dyract complex is a ideal filling material for root caries.
