[Study on the micropermeability of resin-dentin bonding interfaces with ethanol-wet bonding technique].

Objective: To evaluate the micropermeability on bonding hydrophobic adhesive to dentin with ethanol-wet bonding under simulated pulp pressure.

Methods: Twenty-four intact human third molars were used in the study. After the enamel of occlusal surfaces was removed, the molars were randomly divided into six groups.
