Repair of new-generation tooth-colored restoratives: methods of surface conditioning to achieve bonding.
The shear bond strength of repaired resin-modified glass-ionomer cements and polyacid-modified composite resins after different methods of surface conditioning was studied. For the resin-modified glass-ionomer cement, none of the surface treatment methods had a significantly higher repair bond strength than the control. For the polyacid-modified composite, the application of low-viscosity resin after treatment with maleic acid, polyacrylic acid, and air abrasion appeared to be of paramount importance, for it enhanced bonding of the repaired specimens.
