Objective: This study investigated the effect of light emitting diode (LED) and halogen (QTH) photopolymerization on shear bond strength of three types of resin composites. Results: All the specimens cured by LED demonstrated higher shear bond strength than those cured by QTH. There was no statistically significant difference between the two light curing units (LCUs) except for nano-filled resin composite that showed a significant difference. Silorane based resin composite groups were statistically significant higher than nano-filled and hybrid resin composites groups. While nano-filled resin composites was statisticallynon significant higher than hybrid resin composite groups. Conclusions :( 1) The light emitting diode is effective as halogen curing light to obtain resin-composite with no significant difference in shear bond strength to dentin. (2)The silorane-based resin-composite restorative material is promising material regarding bonding efficiency to dentin. Recommendation: It is advisedto cure nano-filled resin composite with light emitting diode (LED) to obtain highershear bond strength to dentin
