摘要/Abstract

摘要： 目的评价临床常用临时粘结剂对永久粘结剂粘固力是否存在影响。方法将75颗离体牙的牙本质表面用4种临时粘结剂处理后，再用Luxacore(冠核材料)、CX(玻璃离子水门汀)、Poly-F（聚羧酸锌水门汀）粘固，测量并比较各组粘结剂粘固力的大小。采用SPSS16.0软件对测量数据进行统计学分析。结果临时粘结剂处理组中对照组与其余4组粘固力的比较有差异（P＜.05），3种永久粘结剂粘固力的比较有差异（P＜0.05），Luxacore组中ZnO组与其余4组粘固力的比较有差异（P＜0.05）。结论临时粘结剂的使用会使永久粘结剂粘固力的下降，含丁香酚临时粘结剂的使用会使树脂类永久粘结剂粘固力的下降，LuxaCore 材料的粘结力强于CX的粘结力，CX的粘结力强于Poly-F的粘结力。

Abstract: Objective To evaluate the influence of temporary cement on bonding strength of permanent cement.Methods The the dentin surfaces of 75 in vitro teeth were treated with four kinds of temporary cements,use Luxacore,CX,and Poly-F cementation.To measure and compare the bonding strength of cements in different groups.The data were analyzed with SPSS 16.0 software package.Results There were differences in bonding strength between control group and the rest four groups in temporary cement processing groups（P＜0.05）.The bonding strength of three kinds of permanent cements was different（P＜0.05）.There were differences in bonding strength between ZnO group and the rest four groups in Luxacore groups（P＜0.05）.Conclusions The bonding strength of permanent cements will be reduced if temporary cements are used.The bonding strength of resin permanent cements will decline if eugenol-containing temporary cements are used.LuxaCore has the stronger bonding strength than CX,while CX is stronger than Poly-F in bonding strength.
