    Abstract:
    PURPOSE: To determine the influence of interchanging self-etching primers and bonding agents on dentin bond strengths. METHODS: Four commercially available self-etching primer dentin bond systems, Clearfil SE Bond (CB), Imperva Fluoro Bond (FB), Mac Bond II (MB), and Unifil Bond (UB) were used. Bovine mandibular incisors were mounted in self-curing resin and the facial dentin surfaces were ground wet on 600-grit SiC paper. The self-etching primers were applied, and four different types of bonding agents were applied on the primed dentin surfaces and cured. The resin-based composites were condensed into the mold (ø4x2 mm) on the dentin surface and light cured. Ten specimens per test group were stored in 37 degrees C water for 24 hours, then shear tested at a crosshead speed of 1.0 mm/minute. Two-way ANOVA followed by Tukey's multiple comparison tests were done. The temperature change of the bonding agents mixed with the primers was monitored during the exothermic polymerization reaction according to the method of ISO standard #4049. The peak temperature and the time required to reach peak temperature were recorded. RESULTS: When different primers were tested with each bonding agent, only the combination of FB with CBP showed statistically lower bond strengths than the other combinations. When different bonding agents were tested with each primer, CB exhibited the highest bond strengths. The only other statistically significant difference was again the combination of FB and CB. Peak temperature decreased and the time required to reach peak temperature increased with the primer/bonding agent combinations compared to the controls. No exotherm was seen for the combination of FB and CBP.
