Abstract

PURPOSE:

To determine the influence of sodium hypochlorite treatment of dentin on shear bond strength and morphology.

MATERIALS AND METHODS:

Shear bond strengths of several dentin bonding agents were compared following specific surface treatments that included manufacturer's directions, etching plus sodium hypochlorite, and sodium hypochlorite alone. The treated surfaces and interfaces between bonding materials and treated surfaces were observed using an FE-SEM.

RESULTS:

Acetone-containing systems yielded equivalent or higher shear bond strengths when sodium hypochlorite was used following etching, as compared with normal procedures. In these cases it is proposed that the adhesive interacts strongly with the treated surface, that contains a high mineral content.
