title: The effect of a peroxidase primer on bond strength of three luting systems to dentin.
abstract: The purpose of the present study was to investigate the effect of an experimental primer containing a microperoxidase (MP-11) with 2-hydroxyethyl methacrylate on adhesive bonding of three different luting systems and dentin. The luting systems prepared were three etch-and-rinse systems (10-3/Super-Bond, 10-0/Super-Bond, 65PA/Super-Bond), a self-etching system (PanaviaF2.0), and a self-adhesive system (SA-Luting). These luting systems were used in conjunction with the MP-11 primer, and were designated as 10-3/MP-11/Super-Bond, 10-0/MP-11/Super-Bond, 65PA/MP-11/Super-Bond, MP-11/PanaviaF2.0, MP-11/SA-Luting, respectively. The dentin surfaces of human premolar teeth were treated, and then bonded with acrylic rods. Shear bond strengths were determined after 24 h of storage in water. The maximum mean bond strength was obtained with 10-0/MP-11/Super-Bond (48.7 +/- 6.6 MPa), followed by 10-3/MP-11/Super-Bond (36.3 +/- 10.2 MPa), 65PA/MP-11/Super-Bond (32.9 +/- 9.2 MPa), 10-3/Super-Bond (26.6 +/- 6.7 MPa), MP-11/PanaviaF2.0 (21.4 +/- 5.6 MPa), MP-11/SA-Luting (17.2 +/- 3.5 MPa), PanaviaF2.0 (16.9 +/- 5.7 MPa), 65PA/Super-Bond (12.8 +/- 2.0 MPa), SA-Luting (11.2 +/- 5.4 MPa), and 10-0/Super-Bond (9.6 +/- 3.9 MPa). The additional use of MP-11 primer significantly improved the bond strengths in the etch-and-rinse systems with 4-META/MMA-TBB resin. It is suggested that the peroxidase has a potential to improve dentin adhesion in the etch-and rinse, self-etching, and self-adhesive systems.
