Resumo
Objectives: To evaluate the effect of root canal sealers (RCS) and specimen aging on the bond strength of fibre posts
to bovine intraradicular dentin.
Material and Methods: 80 teeth were used according the groups - Sealapextm, Sealer 26®, AH Plus® and speci-
mens aging - test with no aging and with aging. The canals prepared were filled using one of each RCS. The posts
were cemented. Roots were cross-sectioned to obtain two slices of each third. Samples were submitted to push-out
test. Failure mode was evaluated under a confocal microscope. The data were analysed by ANOVA, Tukey’s, and
Dunnet tests (α = 0.05).
Results: No significant difference was detected among RCS. Aged control presented higher bond strength than
immediate control. The aging did not result significant difference. Adhesive cement-dentin failure was prevalent
in all groups.
Conclusions: RCS interfered negatively with bonding of fibreglass posts cemented with self-adhesive resin cement
to intraradicular dentin.
