| Popis: | The aim of this study was to evaluate the effect of internal bleaching agents on fibreglass post bond strength to root dentine, seventy bovine teeth were divided into 7 experimental groups (n=10) varying the bleaching agent used: SpH- sodium perborate + 20%hydrogen peroxide; SpW- sodium perborate + distilled water; Cp37- 37%carbamide peroxide; Cp16- 16%carbamide peroxide; Cp10- 10%carbamide peroxide; H- 35%hydrogen peroxide; C- no bleaching agent (control). After bleaching protocols, posts were cemented with self-adhesive resin cement (RelyX U100) and roots were cross-sectioned to obtain two discs for each third. Posts were submitted to micropush-out test and bond strength values (MPa) were submitted to ANOVA in a split-plot arrangement and Tukey s test (p |
