Abstract

Objective: This study was evaluate the microshear bond strength of lowshrinkage composite and nanocomposite with or without flowable lining compositeand self-adhesive composite lining after different aging periods.Materials and methods: Specimens were divided into two equal groups, according toresin composite used (R), where group (R1) represent teeth restored with lowshrinkage resin composite and (R2) represent teeth restored with nanofilled resincomposite. Each group were divided into two subgroups according to Lining materialsused (L), where(L1) represent cavity lining with flowable resin composite and (L2)represent cavity Lining with self adhesive resin composite. Furthermore eachSubgroup were divided into three classes according to aging period(T),where(T1)represent aging period of 24 hours,(T2) represent aging period of twoweeks and (T3) represent aging Period of one month.Results: show that the nanofilled composite showed higher mean micro-shearbond strength than the low shrinkage composite while the lining material and theaging periods had no effect on mean micro-shear bond strength.Conclusion: The shear bond strength between the resin and underlying liningmaterials depend on the composite type rather than the lining resin composite.
