The shear bond strength (SBS) of silver palladium alloys (Au-Pd) luted with four adhesive resin cements (ARC) and two resin-reinforced glass ionomer cements (RRG) was measured at a temperature and humidity simulating the oral environment. Bonding procedures were done in a constant temperature and humidity device at 32 and 92% relative humidity (C-TH), and at room temperature (RT). As a control, Au-Pd was luted as cast. In the four experimental groups, the Au-Pd was luted after sand-blasting only, after priming only with a primer for precious metals, after sand-blasting and priming, and after tin plating. SBS and the mode of fracture varied with the cement and the method of priming the alloy. The SBS obtained for ARC and RRG at C-TH was significantly different from that obtained at RT, which indicates that temperature and humidity should be taken into consideration during bonding procedures.
