Abstract:
The present study compared and evaluated the shear bond strength (SBS) of two types of glass
ionomer cement (GIC), Riva Self Cure HVTM (SDI Ltd., Victoria, Australia) and GC Fuji IX GP EXTRATM (GC
America Inc., Alsip, USA) with and without the use of Riva Bond LCTM (SDI Ltd., Victoria, Australia), a lighted
cured resin-modified glass ionomer cement (RMGIC) universal adhesive. Sixty extracted sound premolars with
prepared exposure of the dentine on the occlusal surface were randomly assigned into four groups according to
the tested restorative materials. Shear bond strength (SBS) tests were performed by using the Shimadzu
Universal Testing Machine at a crosshead speed of 0.5 mm/minute, and the values obtained were statistically
analysed using one-way ANOVA and Tukey tests. The inter-group comparison showed statistically significant
differences in the SBS values between all the test groups (p < 0.001). A stereomicroscope was used to assess
the modes of failure. Adhesive failures were predominant in adhesive groups (>80%) compared to higher
cohesive failures found in the non-adhesive groups (>86%). A Spearman's rho correlation test performed to
determine the association between SBS values and mode of failures had indicated positive correlations between
the adhesive failure and SBS values in the adhesive groups (rs=0.86, p<0.001; rs=0.85, p<0.001) and the
cohesive failure and SBS values in the non-adhesive groups (rs=0.87, p<0.001). These findings support the
improvement in adhesion of GICs to tooth structure with the use of RMGIC adhesive.
