摘　　要：目的:观察P60复合树脂修复老年人后牙牙合面邻牙合面龋洞的临床疗效,并与传统的银汞合金充填疗效相比较。方法:对69位老年人共218颗后牙Ⅰ、Ⅱ类龋洞,采用随机方法分组,109颗采用P60复合树脂充填,109颗采用传统的银汞合金充填,观察2年,并作对比研究。结果:随访2年,P60复合树脂修复体成功率为94.5%,银汞合金成功率为83.5%。经统计学分析,有显著性差异(p<0.01)。结论:2年内P60复合树脂修复老年人后牙Ⅰ、Ⅱ类龋洞的临床疗效令人满意,可替代银汞合金。Objective： To observe the clinical effects of P60 composite resin restored posterior teeth Ⅰ、ⅡType cavities of the elderly, compared with the traditional Silver-amalgam alloy. Methods： 218 cavities of posterior teeth of 69 patients were randomly grouped. P60 composite resin was used in 109 cavities and the traditional silver amalgam in 109 cavities. The comparative study of two groups was observed for two years. Results： By Two-year＇s follow-up, the results indicated that the effect rate of traditional silver amalgam alloy was 83.5% and the effect rate of p60 composite resin was 94.5%. Statistical analysis showed that there was a significant difference （p 0.01）. Conclusion： The clinical efficacy of P60 composite resin restoration of dental cavities of the elderly is satisfactory in observed time. It may be alternative to silver amalgam.
