Universal adhesives applied to deep dentin with different bonding treatments.

Unlabelled: Eighth-generation adhesives may be applied with total etch, selective-etch or self-conditioning, and serve as primers for non-dental substrates.

Aim: To determine the bonding characteristics of universal adhesives applied to the deep pulp wall with different strategies, by means of shear bond strength and laser microscopy.

Materials And Method: Cavities 4 mm deep and maximum width were carved in 36 extracted molars.
