Abstract

The purpose of the current study was to evaluate the adhesive performance of bonding between resin modified glass ionomer luting agents and a silver-palladium-copper-gold alloy. One luting agent (Ionotite F) contained 6-methacryloyloxyhexyl 2-thiouracil-5-carboxylate (MTU-6), whereas the other five agents (Fuji Lute, Fuji Lute BC, Fuji Luting S, Vitremer Luting Cement Fast Set, Xeno Cem Plus) were conventional materials. Cast disk specimens made of a silver-palladium-copper-gold alloy (Castwell M.C. 12) were airabraded with alumina then bonded with the six luting agents. Shear bond strengths were determined before and after thermocycling (20, 000cycles). Bond strength was significantly reduced by application of thermocycling for all groups (p<0.05). The Ionotite F material exhibited the greatest bond strength both before and after thermocycling (50.4, 14.3MPa). It is notable that the post-thermocycling bond strength of the Ionotite F material was statistically comparable to the pre-thermocycling bond strength of the Fuji Lute and Fuji Lute BC materials.
