Abstract: Objective:To investigate the effect of silver diamine fluoride(SDF)on the bonding strength between dentine and glass ion-omer cement(GIC).Methods:1 2 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 )F2 ]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.
