Resumen
The purpose of this study was to compare the resistance when debonding the braces of the enamel after 60 minutes and 24 hours of its fixation with two different adhesive systems. 60 bicuspids where divided into 4 groups of 15 samples each one and were treated with self-etching adhesive SEP Transbond Plus 3M Unitek (group 3 and 4) and conventional adhesive Transbond MIP 3M Unitek (group 1 and 2). The samples were submitted to tangential forces with the universal machine Instron with speed load shedding 1.0 mm/min to obtain the resistance when debonding. After doing the statically analysis ANOVA showed that there are not significant statically difference at the debonding forces between Transbond MIP at 24 hours (mean = 6.8, SD = 2.9) and SEP Transbond at 24 hours (mean = 6.1, SD = 2.8) (t = 0.73 p = 0.46). There is no statistically significant difference between Transbond MIP at 60 minutes (mean = 6.01 SD = 5.2) and SEP Transbond Plus at 60 minutes (mean = 7.35, SD = 5.1) (t = -.71 p = 0.48). It was seen lees than the middle of the remnant adhesive in most of the sample.Key words: Adhesion, adhesive, shear bond strength, adhesive strength.
