Abstract

Objective. To compare push-out bond strength of fiber-posts luted with different adhesive approaches to root canal dentin. Materials and methods. Forty maxillary first incisors were decoronated and endodontically treated. Specimens were randomly distributed into five groups (n = 8) and fiber-posts (DentinPost coated, Komet) were inserted using five different luting materials: etch-and-rinse adhesive systems and corresponding core-and-post material in groups 1 (DentinBond/DentinBuild, Komet) and 2 (XP Bond + SCA/Core-X flow, Densply), self-adhesive resin cements in groups 3 (RelyX Unicem, 3M Espe) and 4 (SmartCem 2, Dentsply) and a self-etch adhesive/resin cement in group 5 (ED-Primer II/Panavia F 2.0, Kuraray). The roots were sectioned into eight 1 mm thick serial slices and within 48 h push-out bond strength was investigated. Statistical analyses were performed using non-parametrical Kruskal-Wallis H-test and Mann-Whitney U-test for differences between experimental groups at p < 0.05. The failure modes were analyzed using Chi square test. Results. The bond strength [MPa] (mean/min–max) for groups 3 (12.35/3.60–32.44), 4 (13.52/4.48–30.69) and 2 (11.15/5.23–35.58) were significantly higher (p < 0.001) compared to groups 1 (6.66/2.34–24.89) and 5 (7.41/0.28–34.18). Adhesive failure between dentin and luting agent was the most frequent failure mode. Conclusions. Bond strength of fiber-posts adhesively luted to root canal dentin was significantly higher when self-adhesive resin cements were used. One (group 2) of the tested core-and-post materials/etch-and-rinse adhesive achieved comparable bond strength values.
