%X this study evaluated the influence of solvent evaporation conditions of acid-etching adhesives. the medium dentin of thirty extracted human third molars was exposed and bonded to different types of etch-and-rinse adhesives: 1) scotchbond multi-purpose (sbmp) ; water-based; 2) adper single bond 2 (sb) ; ethanol/water-based, and 3) prime & bond 2.1 (pb) ; acetone-based. solvents were evaporated at air-drying temperatures of 21oc or 38oc. composite buildups were incrementally constructed. after storage in water for 24 h at 37oc, the specimens were prepared for bond strength testing. data were analyzed by two-way anova and tukey's test (5%). sbmp performed better when the solvents were evaporated at a higher temperature (p < 0.05). higher temperatures did not affect the performance of sb or pb. bond strength at room temperature was material-dependent, and air-drying temperatures affected bonding of the water-based, acid-etching adhesive.
