Comparison of Shear Bond Strength of Resin-Modified Glass Ionomer and Composite Resin to Three Pulp Capping Agents
Background and aims. Present study was designed to compare the bonding strength of resin-modified glass ionomer (RMGI) and composite resin to mineral trioxide aggregate (MTA), MTA mixed with Na2HPO4 (NAMTA), and calciumenriched mixture (CEM). Materials and methods. Thirty specimens of each CEM, N...

description | Background and aims. Present study was designed to compare the bonding strength of resin-modified glass ionomer
(RMGI) and composite resin to mineral trioxide aggregate (MTA), MTA mixed with Na2HPO4 (NAMTA), and calciumenriched
mixture (CEM).
Materials and methods. Thirty specimens of each CEM, NAMTA, and MTA were prepared. Composite and RMGI
restorations were then placed on the samples (15 samples in six subgroups). Shear bond strength was assessed using universal
testing machine. Data were analyzed with two-way ANOVA and post-hoc Tukey test. To compare the bond strength in
subgroups, one-away ANOVA was applied. Significance level was set at P < 0.05.
Results. Bond strength was significantly higher to composite samples compared to RMGI samples (p<0.001). The difference
in bond strength of composite samples between MTA and CEM subgroups (P=0.026) as well as MTA and NAMTA
subgroups (P= 0.019) was significant, but the difference between NAMTA and CEM subgroups (P=0.56) was not significant.
The differences in bond strength in subgroups of RMGI group were not significant (P>0.05).
Conclusion. Regarding shear bond strength to the tested substrates, composite was shown to be superior to RMGI. The
bond of resin composite to MTA was weaker than that to CEM and NAMTA. |
