After an endodontic treatment, many times the remnant is insufficient for the retention of a restorative material, for this reason it is necessary to place a post-stump system to provide retention to the final restoration. With the advent of various materials for esthetic restorations, fiberglass-reinforced resins are now used as post and core systems for the restoration of endodontically treated teeth. The objective of the present work was to compare the bond strength in the push-out test of 2 different types of fiberglass posts; 3M RelyX and Rebilda Post GT (VOCO) bonded with dual cements corresponding to the post brand; RelyX U-200® Automix (3M ESPE) and Rebilda DC (VOCO). A 2-way ANOVA analysis was performed to compare push-out strength between both study groups. Although it was observed that the Rebilda posts presented a slightly higher mean bond strength compared to the 3M posts (with no significant statistical difference P>0.05), the latter are clinically easier to place, which could be a decisive factor for the clinician at the time of choosing a post and its adhesion system.
KEY WORDS: Post, Dual Cement, Push-out test, bond strength.
