Abstract

Purpose: The aim of this study was to examine the shear bond strength (SBS) of conventional glass ionomer incorporated (GI) with flax fibers and/or ethanolic extract of propolis (EEP) with and without thermo-cycling. Materials and Methods: We used 40 extracted sound molars were used in the present study and divided into four equal groups: Group (GI) conventional glass ionomer(control), Group(F)GI incorporated with 5% flax fibers, Group (P) GI incorporated with 1% ethanolic extract of propolis (EEP), Group (FP) GI incorporated with 5% flax fibers and 1% ethanolic extract of propolis (EEP). All samples were prepared for shear bond strength assessment before and after thermocycling. Results: Showed that (F),(P) and(FP) groups had statistically significant highest median shear bond strength values before thermo-cycling in comparison to GI group. While (FP) group had the statistically significant highest median shear bond strength (SBS) after thermocycling. Conclusion:5% Flax fibers and 1% ethanolic extract of propolis (EEP)improved the shear bond strength of conventional glass ionomer.
