- The use of MTA as pulp capping material has been shown to provide better results than calcium hydroxide in terms of biocompatibility and dentinal bridge formation. As pulp capping material, MTA has disadvantage since it has long setting time. Recently, GIC become material of choice to be placed over MTA as base under permanent restoration. The aim of this study was to investigate the shear bond strength of MTA with different setting time, i.e., 45 minutes, 3 hours, and 73 hours when it is bound to conventional and resin modified glass ionomer cement. Thirty six MTA specimens were prepared and assigned randomly into 3 groups of different setting time (45 minutes, 3 hours, and 72 hours). Each group was then divided into 2 sub-groups, i.e., conventional and resin modified GIC, which were used as base. The MTA-GIC shear bond strength was measured using universal testing machine (UTM). Data obtained were analyzed using two-way ANOVA with level of significance 95%. MTA, which was bound to conventional GIC, had lower shear bond strength than resin modified GIC. Results showed that significant differences occurred between resin modified GIC, which applied over MTA that had set for 3 hours, and other groups (p < 0.05). It can be concluded that resin modified GIC as base can be placed over MTA that has set for 3 hours since it has the greatest shear bond strength.
