title: In vitro evaluation of two new dentin adhesive systems.
abstract: Two new experimental dentin adhesive systems were evaluated to determine in vitro dentin bond strengths and marginal microleakage. Scanning electron microscopy examinations were also conducted on one of the systems that was designed to modify the smear layer. Mean shear bond strength for the two experimental systems were 6.77 +/- 1.94 MPa and 18.73 +/- 2.4 MPa. Marginal microleakage from the enamel margin was not observed and the experimental primer system limited leakage from the dentin margins. The SEM examinations showed that the primer did not significantly alter the smear layer on the prepared dentin surface.
