The influence of different cements on the pull-out bond strength of fiber posts

Statement of problem Glass fiber posts are commonly used to provide adequate support and retention for the restoration of endodontically treated teeth, but their resistance to dislodgement depends on their adhesion to root dentin.

Description
Summary:Statement of problem Glass fiber posts are commonly used to provide adequate support and retention for the restoration of endodontically treated teeth, but their resistance to dislodgement depends on their adhesion to root dentin. Purpose The purpose of this study was to assess the effect of cement type on the pull-out bond strength of fiber posts. Material and methods Seventy maxillary canines were endodontically treated and then divided into 7 groups according to the cement used for fiber post cementation as follows (n=10): RelyX Unicem, BisCem, RelyX Luting 2, RelyX ARC, Panavia F, Enforce, and Allcem. The specimens were subjected to a pull-out bond strength test in a universal testing machine at a crosshead speed of 0.5 mm/min. The results, in newtons, were analyzed with 1-way ANOVA and the Tukey post hoc test (α=.05). Results RelyX Unicem (472.3 ±8.9 N), BisCem (506.6 ±9.2 N), RelyX ARC (498.0 ±8.2 N), Panavia F (502.3 ±7.0 N), and Allcem (470.0 ±11.3 N) presented significantly higher bond strength than RelyX Luting 2 (241.8 ±9.70 N) and Enforce (309.5 ±6.3 N) cements (mean ±SD; P
