摘要：
This study evaluated the effects of remaining dentin thickness (RDT), different smear layers, and aging on the microtensile bond strength (mu TBS) of universal adhesives to dentin when applied in self-etch mode. Ninety-six human third molars were randomly allocated to 12 groups (n=8) based on adhesives: Clearfil (TM) SE Bond 2 (SE, control), Clearfil (TM) Universal Bond (CU) and ScotchBond (TM) Universal Adhesive (SB); smear layers: prepared either with 600-grit SiC paper (P) or regular diamond bur (B); and aging: stored in distilled water at 37 degrees C for 24 hours (24h) or 1 year (1y). mu TBS was significantly affected by the type of adhesives, smear layers, and aging (p<0.001). A statistically significant and positive linear relationship was also observed between mu TBS and RDT (p<0.05) in all the tested groups, except for SEB1y and CUB24h (p>0.05). RDT, smear layer types, and aging can influence the bonding performances of universal adhesives when applied in self-etch mode.
