Aim: To compare the bond strength of fiberglass posts luted with different adhesive luting protocols. Materials and methods: Thirty bovine teeth that underwent endodontic treatment were used. The crowns were removed, and the root canals were prepared. In the first group, the posts were cemented with an etch-and-rinse protocol with universal adhesive and resin cement; for the second group, a self-etching protocol with universal adhesive and resin cement was adopted; for the third group, a protocol with self-adhesive cement was adopted. The roots of the teeth were sectioned into 2-mm thick specimens, corresponding to the middle, cervical, and apical thirds of the space prepared for the post. The specimens were pushed out using a universal testing machine. The normality of the data was tested by the Shapiro–Wilk test, and statistical analyses included ANOVA and Bonferroni test. Results: The mean adhesion force was 21.2 ± 4.7 MPa in the first group, 22.6 ± 5.1 MPa in the second, and 12.3 ± 2.1 MPa in the third group. At the cervical level, the mean adhesion force was 17.5 ± 5.2 MPa, at the level of the middle third, it was 17.7 MPa ± 5.4, and at the apical level, 21.0 ± 7.3 MPa. Conclusions: There were no significant differences in the mean adhesion's forces between groups 1 and 2, while the values of group 3 were significantly lower than those of the other groups. Clinical significance: This research allows us to know the impact of bonding systems on the different cementation protocols for fiberglass posts.
