银粉玻璃离子和银汞合金用于治疗老年根面龋的疗效观察

摘要

Objective To observe the clinical efficacy of filling posterior root caries with glass ionomer silver reinforced restorative and amalgam for elderly patients. Methods 325 teeth with posterior root caries were divided into two groups randomly and filled with glass ionomer silver reinforced restorative, amalgam respectively, followling up for two years. Results The success rate of glass ionomer silver reinforced restorative group reached 91.41%, which of amalgam restorative group is 67.28%. The difference between the two groups was statistically significant(P<0.05). Conclusion Filling posterior root caries with glass ionomer silver reinforced restorative for elders achieved a better effect.%　　目的观察银粉玻璃离子和银汞合金治疗老年患者后牙根面龋的临床疗效.方法将325颗根面龋坏后牙随机分为两组，分别采用银粉玻璃离子、银汞合金两种材料进行充填，随访观察2年.结果银粉玻璃离子填充组的成功率达91.41%，高于银汞合金填充组的7.28%，组间差异有统计学意义(P<0.05).结论银粉玻璃离子治疗老年后牙根面龋疗效较好.
