Abstract

Objetive: The aim of this study was to evaluate the microtensile-bond strength of four commercial adhesive systems. Methods: Twenty bovine incisors had the buccal dentin exposed and restorations were made using four different adhesive systems (n=5): Magic Bond DE and OptiBond Solo (two-step etch-and-rinse), One-Up Bond F and Adper Prompt L-Pop (one-step self-etch). Teeth were sectioned perpendicularly to the adhesive interface to obtain beams of 1mm² of section. The beams were submitted to microtensile-bond strength on a universal testing machine. Data were analyzed by one way ANOVA and Tukey post hoc at a 5% of significance. Results: The mean bond strength values were 48.81±0.56 to Magic Bond DE, 47.52±13.03 to OptiBond Solo, 44.68±13.32 to One-Up Bond F and 31.59±11.81 to Adper Prompt L-Pop. Adper Prompt L-Pop exhibited lower bond strength than etch-and-rinse adhesive systems (p<0.05). Conclusion: Adper Prompt-L-Pop showed the lower immediate bond strength.
