摘　　要：目的比较3M光固化玻璃离子和DMG爱诺赛光固化复合体2种垫底材料对后牙深龋充填的术后敏感性。方法84颗深龋后牙,随机分为3M组和DMG组,3M组垫底材料为3M VitrebondTM光固化玻璃离子,DMG组垫底材料为DMG Ionosit-Baseliner爱诺赛光固化复合体,自酸蚀后,两组上层均加压填充3M FiltekTMZ350纳米复合树脂,于修复后1 d、1周、1个月和3个月,对敏感发生率和自觉疼痛程度进行比较。结果术后1 d、1周和1个月,3M组和DMG组的术后敏感率和自觉疼痛程度无差异(P>0.05),术后3个月,3M组的术后敏感率和疼痛程度低于DMG组,差异有统计学意义(P<0.05)。结论在后牙深龋治疗中,使用光固化玻璃离子垫底材料可降低术后敏感的发生。Objective To compare the postoperative sensitivity of deep caries treated with 3M light cured glass ionomer and DMG Ionosit-Baseliner. Methods A total of 84 posterior teeth with deep caries from 84 patients were randomly divided into two groups： 3M group and DMG group. 3M VitrebondTM light cured glass ionomer was used as liner material in Group 3M and Ionosit-Baseliner was used in Group DMG. After etching,both groups were filled with 3M FiltekTM Z350 nano composite resin. The sensitivity and the pain degree were evaluated and compared 1 day, 1 week,1 month and 3 months after operation. Results There was no signifi ence in the postoperative sensitivity and self-pain level between the two groups after 1 day, 1 week and 1 month （ P 〉 0.05 ）. with group DMG, the incidence of sensitivity and self-pain level were lower in group 3 M 3 months after operation （P 〈 0.05 sions In posterior restorations,the light cured glass ionomer can reduce the incidence of postoperative sensitivity. ant differ Compared ~ Conclu-
