Methods: Forty-eight extracted maxillary incisors were randomly divided into four groups according to the tested sealer (n = 12): group 1 control (only gutta-percha points, no sealer); group 2 AH Plus Jet (resin-based sealer); group 3 Endofill (zinc oxide-eugenol-based sealer); and group 4 iRoot SP (calcium silicate-based sealer). All root canals were filled with gutta-percha, and groups 24 additionally received one of the sealers. Fibre posts were cemented with the self-adhesive resin cement Clearfil SA Cement. The specimens were sectioned in the coronal, middle and apical regions, producing three slices of 1 mm thickness. The push-out test was performed. All data were submitted to ANOVA and Tukey tests (a = 0.05). Results: No statistically significant differences were found between the control group, AH Plus Jet and iRoot SP (p > 0.05). The Endofill sealer showed significantly lower bond strength compared to the other sealers and the control group (p < 0.05). Conclusions: The calcium silicate-based sealer did not adversely affect the bond strength of the fibre posts cemented with self-adhesive resin cement.en10.1111/j.1834-7819.2012.01671.xinfo:eu-repo/semantics/closedAccessiRoot SPpost bond strengthroot canal sealerArticle57216617022624756Q1WOS:000304438300009Q2
