Background and Aim: Sandwich technique is one of the most common   methods in dentistry in which resin-modified  glass  ionomers  due to advantages  such  as  fluoride  release and adhesion  to tooth  structure  are  used  with  composite  restorations. The aim of this study is assessment of shear bond strength between resin modified glassionomer and composite using different bonding agents.

Material and Method:  In this invitro study, 60 resin modified glass ionomer samples (GC FUJI 2LC) were prepared. .In the first group, without  the use of bonding agent and in other two groups  with the use of bonding agents( SE bond and  S3  bond) composite adhered to  glass ionomer.After placing the samples  in distilled water  in incubator with temperature 37/5° C for one  week, shear bond strength of samples was  measured by the universal machine test .  One way analysis of variance and Tukey test were used for analyzing the data and comparison between groups.

Results: The maximum amount of the bond strength was for specimens bonded with SEbond(13/09 Mpa)  and  the lowest amount was in control group(5/3 Mpa) .  The mean shear bond strength was significantly different between the four groups.(p<0.05)

Conclusion: The maximum shear bond strength between resin-modified glass ionomer and composite resin was related to SE bond therefore using of this bonding agent in sandwich technique is recommended.

Keywords: Shear strength, composite resin, resin modified glass ionomer, bonding agent.
