摘要：

The purpose was to evaluate the effect of air-drying dentin surfaces on the microtensile bond strength (mu TBS) of a solvent-free onestep adhesive (Bond 1 SF). Twelve human molars were ground with 600-grit SiC paper. Before applying bonding agent, the dentin surface was rinsed with distilled water and blot-dried with tissue paper, followed by air-drying for 0, 3, 30, and 60 s using with a dental air syringe. After applying and curing Bond 1 SF, resin composite was incrementally built up. Specimens were then stored in distilled water for 24 h and then mu TBSs were measured at a cross-head speed of 1 mm/min. Higher mu TBS were observed when the dentin surface was air-dried for 3 s (33.2 +/- 6.8MPa)>0 s (26.7 +/- 4.5MPa)>30 s (22.6 +/- 5.5MPa)=60 s (20.4 +/- 5.0MPa). The results suggested that prolonged air-drying of the dentin surface removed water and decreased the bond strengths of Bond 1 SF.
