The dentin bonding of selected adhesive cement systems

: This in vitro study reports shear bond strengths of two dentin bonding agents (DBA's) with various composite luting resins. For a better imitation of the surface of vital human dentin, all materials were tested with dentin under intrapulpal pressure (19.6 cm/36 cm H2O) and exposed to thermal cycling (x 1500, 5 degrees C/55 degrees C). For all testing groups the bonding agent and the composite resin were light cured at the same time. In the group of AllBond2 the combination with Dual Cement resulted in slightly better bond strength than with the other luting resins. In the group of A.R.T. Bond none of the combinations achieved the expected results.
