The purpose of the current study was to examine the effectiveness of organic sulfur compounds on bonding durability between silver-palladium-copper-gold alloy and acrylic adhesive. The Metal Link (ML) and V-Primer (VP) primers were assessed; the ML primer contains10-methacryloyloxydecy1-6, 8-dithiooctanoate (MDDT) for noble metal and6-methacryloxyhexylphosphonoacetate (MHPA) for base metal in acetone, while the VP includes 6-(4-vinylbenzyl-n-propyl) amino-1, 3, 5-triazine-2, 4-dithione (VTD) in acetone. After air-abrasion with alumina, cast disk specimens made of silver-palladium-cupper-gold alloy were primed and bonded with different acrylic adhesives (Multi-Bond or Super-Bond C&B). Unprimed specimens were also prepared as controls for each adhesive. Regarding the Super-Bond adhesive, both primers had significant effects on the post-thermocycling (100, 000cycles) shear bond strengths. Concerning the Multi-Bond adhesive, the post-thermocycling strength for the ML primer was not statistically (p>0.05) different from that for the unprimed group.
