Abstract
Purpose: To assess the influence of simulated pulpal pressure (SPP) on the microtensile bond strength (mu TBS) of four simplified luting strategies to indirect composite restorations.
Materials and Methods: Dentin disks from 40 human molars were prepared and treated with 4 different techniques: (1) SB+ARC: two-step etch-and-rinse adhesive + conventional dual-curing resin cement (Adper Single Bond 2 + RelyX ARC, 3M ESPE); (2) ED+PAN: self-etching primer + conventional dual-curing resin cement (ED Primer + Panavia F2.0, Kuraray Medical); (3) S3+ PAN: one-step self-etching adhesive (Clearfil S3, Kuraray) + Panavia F2.0; (4) U200: self-adhesive resin cement (RelyX U200, 3M ESPE). Pre-made indirect composite restorations (Filtek Z100, 3M ESPE) were luted onto the specimens. The luted specimens were cut into resin-dentin beams and the mu TBS was tested after two different aging regimes: water storage at 37 degrees C for one week (control) or three months under 20 cm H2O simulated pulpal pressure (SPP). The mu TBS data was analyzed with two-way ANOVA and Tukey's test (p < 0.05).
Results: SB+ARC showed significantly higher mu TBS after both aging regimes (p < 0.001). The statistically significantly lowest mu TBS was measured for control S3+ PAN and U200 after 3 months SPP (p < 0.001). S3+ PAN was the only group not negatively affected by SPP (p = 0.699).
Conclusions: Two-step etch-and-rinse adhesives associated with dual-curing conventional resin cements may achieve the highest mu TBS, even after 3 months of SPP. The one-step self-etching adhesive along with the dualcuring conventional resin cement was able to maintain bond stability.
