目的:评价ART(非创伤性充填)技术中银汞合金和玻璃离子在老年人龋齿Ⅰ类、Ⅱ类洞的充填效果。方法: 将204例(286颗牙)罹患龋齿且同一洞型的患者按不同充填材料分为两组:汞合金组103例(146颗牙)和玻璃离 子组101例(140颗牙)。汞合金组采用银汞合金粘结充填治疗;玻璃离子组采用玻璃离子充填治疗。2年后随访 复诊患者有192例,患牙256颗。结果:Ⅰ类洞充填成功率:汞合金组为69.23%(36/52),玻璃离子组为72.22% (39/54),两组比较,无显著性差异(P>0.05);Ⅱ类洞充填成功率:汞合金组为58.97%(46/78),玻璃离子组为48. 61%(35/72),两组比较,有显著性差异(P<0.01)。结论:ART技术适合于老年人龋齿的充填治疗,对不同洞型的 龋齿采用不同的充填材料,可提高治疗的成功率。

Objective:To appraise the filling effect of silver amalgam and glass-ionomer in the elderly decayed tooth Ⅰ&Ⅱ type cavity using ART technique,to expands the treating range of the ART technique. Methods: Two hundred and four decayed tooth sufferer of the 60 years old upwards in the Jiangmen old cadre activity center and agedness university were divided into two groups in the same type randomly;one group for silver amalgam filling , the other for glass-ionomer. Results: One hundred and ninety two sufferer which had 256 decayed teeth after two years were followed up. There were 36 cases (69.23%) in theⅠ type sufferers who fill silver amalgam,46 (58.97%) in the Ⅱtype, 39 (72.22%) in the Ⅰtype sufferers who fill glass-ionomer,35 (47.30%) in the Ⅱtype, were succeed. So the effect to fill the silver amalgam was superior than the glass-ionomer. Conclusion:ART technique is not only adapt to the treatment of the forepart young one decayed tooth sufferers,but also to agedness. In the filling of differ type cavity, suggest selecting differ materials to increase the success rate.
