Aim: The study aimed to evaluate the influence of irrigating solutions on bond strength (BS) of fiber posts using different luting systems after aging. Methods: Bovine teeth (N = 96) were randomly (8 groups, N = 12), sectioned, endodontically treated and root canals were prepared. The 96 bovine teeth were divided into four groups according to luting systems as conventional light-cure (RelyX ARC), self-adhesive (RelyX U200 and Panavia F),dual - cure self - etch, and self - adhesive (SeT PP). Each of the four groups was further divided into two subgroups using 2% chlorhexidine (CHX) gel or 5.25% sodium hypochlorite (NaOCl) as the irrigating solution. After post cementation, the metal-ceramic crowns were positioned. After 48 h, all samples were submitted to 1,000,000 thermal cycles. After water storage, push-out test was performed. The data were analyzed using two-way ANOVA and Tukey's test (P = 0.05). Results: CHX gel BS means were statistically higher than NaOCl means when posts were cemented with the conventional or dual-cure self-etch and self-adhesive resin cements; no significant statistical differences were observed between groups CHX gel or NaOCl treatments for the dual-cure self-adhesive resin cements. Conclusion: The irrigation solution used on endodontic treatment before luting procedures with conventional or dual-cure self-etch and self-adhesive resin cements of glass fiber posts improved long-term BS after aging.
