Bonding to etched, physiologically hydrated dentin.

This study evaluated the shear bond strengths of resin composite to dentin using Kanca's "total-etch" technique (etching with 37% phosphoric acid, application of Tenure Solutions A and B, and application of Scotchbond 2 Adhesive). Bonding was done under different conditions, to specimens with or without hydrostatic pressure. Shear bond strengths were 20.1 MPa to dentin under simulated physiologic pressure, and 15.2 MPa to dentin without pressure.
