Fatigue resistance of dentin bonds prepared with two- vs. three-step adhesives: Effect of carbodiimide.

ABSTRACT: The application of a cross-linker to demineralized dentin is reportedly effective at extending the durability of dentin bonds.

Objective

To compare the effect of a cross-linker pretreatment on the fatigue crack growth resistance of resin-dentin bonds prepared with a two- vs. three-step adhesive system.

Methods

Bonded interface Compact Tension (CT) specimens were prepared using commercial two- and three-step etch-and-rinse adhesives and compatible hybrid resin-composite. For the treated groups, adhesive bonding was preceded by a 1min application of an experimental carbodiimide (EDC) conditioner to the acid-etched dentin. The control groups received no such treatment. The fatigue crack growth resistance was examined after storage in artificial saliva at 37°C for 0, 3 and 6 mont
