Abstract


OBJECTIVES
This study determined the effect of the air-stream application time and the bonding technique on the dentin bond strength of adhesives with different solvents. Furthermore, the content and volatilization rate of the solvents contained in the adhesives were also evaluated.
MATERIALS AND METHODS
Three adhesive systems with different solvents (Stae, SDI, acetone; XP Bond, Dentsply De Trey, butanol; Ambar, FGM, ethanol) were evaluated. The concentrations and evaporation rates of each adhesive were measured using an analytical balance. After acid-etching and rinsing, medium occlusal dentin surfaces of human molars were kept moist (conventional) or were treated with 10% sodium hypochlorite for deproteinization. After applying adhesives over the dentin, slight air-stream was applied for 10, 30 or 60 sec. Composite cylinders were built up and submitted to shear testing. The data were submitted to ANOVA and Tukey's test (alpha = 0.05).
RESULTS
Stae showed the highest solvent content and Ambar the lowest. Acetone presented the highest evaporation rate, followed by butanol. Shear bond strengths were significantly affected only by the factors of 'adhesive' and 'bonding technique' (p < 0.05), while the factor 'duration of air-stream' was not significant. Deproteinization of dentin increased the bond strength (p < 0.05). Stae showed the lowest bond strength values (p < 0.05), while no significant difference was observed between XP Bond and Ambar.
CONCLUSIONS
Despite the differences in content and evaporation rate of the solvents, the duration of air-stream application did not affect the bond strength to dentin irrespective of the bonding technique.

Figure

  • Figure 1 Allocation of the teeth for experimental conditions in a 2 × 3 × 3 factorial study design.

  • Figure 2 Box-plot graph for the results of solvent content. Different letters indicate significant differences (p < 0.05).

  • Figure 3 Box-plot graph for the results of evaporation rate. Different letters indicate significant differences (p < 0.05).

  • Figure 4 Distribution of failure modes among the experimental conditions. Except for Stae, dentin deproteinization reduced the number of Type I failures and increased the number of Type III failures. Type I, adhesive failure; Type II, mixed failure with more than 50% adhesive; Type III, mixed failure with less than 50% adhesive.
