Aim : The aim of this study was to evaluate & compare the shear bond strength of different restorative composite resins and glass ionomer cement over white mineral trioxide aggregate. Method: Forty specimens of White MTA were condensed into cavities prepared in acrylic blocks and divided into four groups (ten each). In group one, Adper single bond (two-step ′total- etch adhesive′) bonding agent and Z250 composite, in group two Xeno V one component self-etching adhesive bonding agent and CeramX Mono composite, in group three Vertise Flow flowable composite and in group four Glass ionomer cement were placed over White MTA. The shear bond strength was measured in the universal testing machine and the results were analyzed by one-way analysis of variance test. Results: Adper single bond 2 and Z250 composite had statistically significant (p<0.005) higher shear bond strength values than Xeno V and Ceram X Mono composite, Vertise Flow and GIC. Conclusion: The placement of composite Z250, used with Adper single bond, over White MTA as final restoration may be appropriate.
