Abstract
This study examined the influence of different surface conditioning methods on composite-to-composite microtensile bond strength. Thirty two-year old composite resin discs were randomly divided into three groups according to the different mechanical/chemical surface pretreatment tested: (1) 38% hydrogen peroxide (H2O2) -treatment; (2) 50-mu m aluminum oxide sandblasting; (3) no treatment. Depending on the intermediate agent applied, two subgroups were created: (A) three-step adhesive system; (B) prehydrolyzed silane coupling agent + three-step adhesive system. Microtensile bond strength measurements were performed and the data were statistically analyzed with Kruskall-Wallis Analysis of Variance and Dunn's multiple range test for post hoc comparisons (p lt 0.05). Failure mode was evaluated with a scanning electron microscope. Changes in composite surface topography after H2O2 treatment were also investigated. Composite repair strength did not benefit from H2O2 treatment and adhesive ...application. Preliminary sandblasting significantly improved interfacial bond strength regardless of the intermediate agent applied. No changes in surface texture were produced after H2O2 treatment. An atypical fracture pattern was detected at the interfacial level between H2O2-treated composite surfaces and the overlying adhesive and composite. H2O2 treatment affected the composite-to-composite repair strength: a compromised resin polymerization may occur, resulting in a poor interfacial quality and a weak bond. Sandblasting still remains a reliable technique for composite repair.
