AbstractObjective:To observe and evaluate the efficacy of 3M glass ionomer bined with photosensitive resin for restoration of severe damage in posterior :268 damaged teeth were firster molar was covered with 3M glass ionomer cements,modified with acid and then with a layer of photosensitive cure and further modification was :The symptoms of sensitivity disappeared in all damaged up to the 12th month after the restoration,the efficacy and the rate of satisfication ranged from %~100%.Decayed teeth deleveoped in %.Conclusion:3M glass ionomer bined with photosensitive resin can be used effectively for restoration of severe damage in posterior tooth.

后牙磨耗严重,牙本质暴露的面积较大,常伴严重过敏,不易备洞以取得固位,治疗困难。传统治疗过程对牙体磨损大,患者难以耐受。应用新型树脂材料的修复方法无需磨损牙体,并可避免传统方法治疗后合并症[1]。3M含氟玻璃离子材料的使用改善了与牙本质的粘结,直接消除敏感症状[2];光敏树脂进一步增加了与牙体的粘结面积,充填后牙体更加耐磨损。现将我院采用3M含氟玻璃离子和光敏树脂联合修复后牙凹坑式严重磨耗126例报道如下。
1 材料与方法
临床资料收集2003年1月至2008年9月间连续经治患者126例,共268颗患牙。全部为活髓牙,均对冷热刺激敏感,但均无晚间自发痛。其中第一磨牙112颗,
