摘　　要：为了减轻中龋治疗后的敏感症状和提高充填物的牢固性。采用自身对照设计，选择９４ 例１８８ 只中龋患牙。其中实验组９４ 只患牙。应用碘化银法涂层后银汞充填；对照组９４ 只患牙，应用聚羧酸锌水门汀垫基后银汞充填。结果显示：涂层和垫基对温度即刻反应的比较差异无显著性（ Ｐ＞ ００５） ，经６ 个月和１８ 个月对两组充填物完好情况观察对比，实验组优于对照组（ Ｐ＜ ００５ 和 Ｐ＜ ０００５） 。表明：碘化银法涂层后银汞充填是治疗中龋的一种较好方法。To decrease the hypersensitivity of dentin and increase the consistence of filling material aftercaries treatm ent ,in this self controlled trial ,94 dentin caries of 94 patients were treated by silver a malga mfilling after sm earing layer with silveriodide ,w hile in the control group ,other 94 caries of these 94 patientswere treated by silver am alga m filling after rebasing with polycarboxylate ce ment . It shows that the im me diate reaction to tem perature in these tw o groups have no significant defference ,but at 6th and 18th monthafter treatment ,the intactness of the filling material in experimental group was significantly better thanthatin control group( P< 0 .05 and P< 0 .005 respectively) . These data suggest that smearing layer withsilver iodide before silver a malgam filling m ay be ideal for the treatm ent of dentin caries .
