dc.description.abstract | Objective: The purpose of this study was to assess the push-out Bond strength of glass fiber posts to root dentin after cementation with glass ionomer (GICs) and resinmodified glass ionomer cements (RMGICs). Material and Methods: Fifty human maxillary canines were transversally sectioned at 15mm from the apex. Canals were prepared with a step back technique until the application of a #55 K-file and filled. Post spaces were prepared and specimens were divide into five groups according to the cement used for post cementation: Luting & Lining Cement; Fuji II LC Improved; RelyX Lutin: Katec Cem; and Ioneseal. After cementation of the glass fiber posts, all roots were stored at 100% humidity until testing. For push-out test, 1-mm thick slices were produced. The push-out test was performed in a universal testing machine at a crosshead speed of 0.5 mm/min and the values ( MPa) were analyzed by Kolmogorov-Smirnov and Levene’s tests and by two-way ANOVA and Tukey’s post hoc test at a significance level of 5%. Results: Fiber posts cemented using Luting & Lining Cement, Fuji II LC improve, and Ketac Cem presented the highest bond strength to root dentin, followed by RelyX Luting. Ionoseal presented the lowest bond strength values ( P> 0.05). The post level did not influence the bond strength of fiber posts to root dentin ( P=0.148); The major cause of failure was cohesive at the cement for all GICs and RMGICs. Conclusions: Except for Ionoseal, all cements provided satisfactory bond strength values. | en |
