Abstract
The bond strength of glass ionomer cement to dentin treated with cleanser and subsequently mordants was measured to develop the best treating system. Also, the effect of the chosen system on the bonding of five other cements to dentin was investigated.
The bond strength of glass ionomer cement to dentin subjected to 37°C water immersion for 1 day was improved by using 0.5M maleic acid and three mordants containing Fe (III) ion. Particularly, 10% FeCl3⋅6H2O and 10% FeNH4 (SO4)2⋅12H2O solutions greatly improved the bonding.
Although the bond strength of three other polycarboxylate-based cements such as polycarboxylate and glass ionomer cements was improved using 0.5M maleic acid and 10% FeNH4(SO4)2⋅12H2O, that of two resin cements to dentin was not improved.
