摘　　要：目的:评价氟化氨银溶液(silver diammine fluoride,SDF)对人工龋牙本质和玻璃离子粘固剂(glass ionomer cement,GIC)之间的微拉伸粘接强度的影响。方法:将12颗人离体磨牙制备成脱矿牙本质和未脱矿牙本质2组标本,均分为对照组、氟化氨银组及氟化氨银与光固化联合处理组(n=20),将处理完成的牙本质与GIC富士IX粘接,24 h后对标本进行切割及微拉伸强度试验,最后用扫描电镜观察牙本质与GIC之间的超微结构,并进行数据统计分析。结果:脱矿后牙本质的粘接强度显著高于未脱矿的牙本质(P<0.01)。经过光固化SDF处理的人工龋牙本质的粘接强度数值显著高于只经SDF处理的人工龋牙本质的粘接强度(P<0.01)。结论:SDF处理的人工脱矿牙本质与GIC之间的微拉伸粘接强度得到显著提高。Objective： To investigate the effect of silver diamine fluoride（SDF） on the bonding strength between dentine and glass ion- omer cement（GIC）. Methods： 12 extracted sound molars were prepared into dintine samples and distributed into sound dentine group and demineralized dentine group. According to the treatment methods, the samples in each group were respectively divided into 3 sub- groups： A（control group）, B[coated with 38% Ag（NH3）F21 and C（SDF treatment with additional lighting-curing）（n =20）. Then a hand-mixed conventional glass ionomer cement Fuji IX was placed on the dentine surface. After 24 h, micro tensile bond strength test and scanning electron microscope （SEM） analysis were conducted. Results ： The bonding strength of demineralized dentine was higher than that of sound dentine（ P 〈 0.01 ）. SDF with additional lighting-curing treated dentine showed a higer bonding strength value than only SDF treated dentin（ P 〈 0.01 ）. Conclusion： SDF may improve the bonding between dentine and GIC.
