In this study, human dentin, composite core resin and dental alloy (Ag-Pd-Cu-Au) were bonded to the stainless steel by two kinds of adhesive cements and a glass ionomer cement. The adhesive strength of each specimen was measured after 24 hours (thermocycle 0) and after thermocycling 5, 000 times as well and compared with one another.
Furthermore, the influence of pretreating agent on adhesive strength to the composite core resin and the dental alloy was examined.
The following results were obtained;
1. Panavia 21 exhibited high early bond strength and stable durability to the human tooth andthe dual-cured composite core resin comparing with the other cements.
2. Super bond C & B showed high early bond strength to the human tooth, the dual-curedcomposite core resin and the Ag-Pd-Cu-Au alloy, but its durability was very poor.
3. After applying pretreating agent, the durability of Panavia 21 to the Ag-Pd-Cu-Au alloydecreased remarkably.
4. Fuji BOND indicated low early adhesive strength and very poor durability.
