摘　　要：目的:比较不同正畸黏结剂在黏结强度、残留情况及预防釉质脱矿的效果。方法:选取2010年2月～2011年7月于本院进行正畸治疗的28例患者为研究对象,将其随机分为A组(树脂型黏结剂组)和B组(光固化树脂加强型玻璃离子黏结剂组),每组各14例,将其拔除牙干预处理后不同时间段牙齿黏结强度、黏结剂残留情况进行比较,比较两组患者不同治疗时间段的釉质脱矿情况,并进行统计学分析。结果:不同时间两组材料的黏结强度、黏结剂残留情况及釉质脱矿的实验结果差异具有统计学意义(P<0.05),B组黏结强度高于A组,黏结剂残留情况及釉质脱矿程度低于A组。结论:光固化树脂加强型玻璃离子黏结剂在增强黏结强度及减少黏接剂残留的效果更佳,且可更能有效地预防釉质脱矿。Objective： To compare the effect of different orthodontic adhesives on bonding strength, agent residue and enamel demineralization. Methods： A total of 28 patients with orthodontic treatment in our hospital from February 2010 to July ？,011 were selected as research objective, and they were randomly divided into group A（resin bonding agent group）and group B（light cured resin reinforced glass ionomer cement group）with 14 cases in each group, then the bonding strength,agent residue situation of extraction teeth and enamel demineralization situation of two group after the intervention at differenttimes were compared, and statistically analyzed. Results： There were significant differences m bonding strength, agent residue and enamel demineralization between two groups （P^0. 05）. The bonding strength of group B after the intervention at different times were all stronger than those of group A,agent residue situation and enamel demineralization were weaker than those of group A. Conclusions： Light cured resin reinforced glass ionic adhesives can strengthen bonding strength, reduce agent residue, and it can effectively prevent the enamel demineralization.
