Comparative evaluation of pull-out bond strength of fiber post using different luting cements in endodontically treated teeth: An in-vitro study

[摘要] Aim: This study was aimed to evaluate and compare the pull‑out bond strength of fiber post using glass ionomer cement (GIC), resin‑modified glass ionomer cements (RMGIC), self‑etch adhesive resin cement, and self‑adhesive resin cement in endodontically treated teeth. Materials and Methods: Forty single‑rooted teeth with single canal were decoronated, endodontically treated, post space were prepared and divided into four groups (n = 10) based on the cement used for luting the fiber post. Group 1: GIC, Group 2: RMGIC, Group 3: Self etch adhesive resin cement, Group 4: Self‑adhesive resin cement. Pull‑out test was evaluated for the prepared samples. Statistical analysis was performed using analysis of variance and Tukey’s test (P = 0.05). Results: The mean pull‑out bond strength of Group 4 was statistically higher than Group 1,2 and 3. Group 1 showed the least bond strength among all the groups. Conclusion: Within the limitation of this study, self‑adhesive resin cements provide better bond strength of fiber post to root canal compared to self‑etch adhesive resin cement and glass ionomer based cements.
