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.

Effects of dentin permeability and hydration on the bond strengths of dentin bonding systems.

This in vitro study evaluated the shear bond strengths of five adhesive systems bonded to dentin with and without simulated physiologic hydrostatic pressure. To simulate pulpal pressure, bonding procedures were done on extracted teeth connected to a hydration apparatus. Bond strengths were significantly less for each adhesive system under simulated physiologic conditions. Amalgambond had significantly higher bond strengths than Clearfil Photo Bond, Gluma, Scotchbond 2, or Tenure, either with or without simulated pulpal pressure.
