title: Effect of two resin cements and two fiber post surface treatments on push-out bond strength between fiber post and root dentin.
abstract: To evaluate the effect of fiber post surface treatments on push-out bond strength between fiber post and root dentin.
  
  
  
  Sixty bovine mandibular teeth (N=60) were sectioned (16 mm), prepared (12 mm), embedded with acrylic resin and then allocated into six groups (n=10): Gr1- Silane coupling agent (Sil)+Conventional resin cement AllC em (Al C); Gr2- Sil+Conventional resin cement RelyX ARC (ARC); Gr3- tribochemical silica coating (TBS)+AlC; Gr4- TBS+ARC; Gr5- No treatment (NT)+AlC; Gr6- NT+ ARC. Specimens were sectioned in four slices (2 mm) and submitted to push-out test. Fracture analyses were executed at x200. The values of the push-out bond strength were submitted to two-way ANOVA and Tukey test (α=0.05).
  
  
  
  Resincement did not affect the bond strength values (p=0.9674), fiber post surface treatment affected the push-out bond strength (p=0.0353), interaction between factors did not affected the values (p=0.338). Tukey test did not show differences between the groups. Adhesive failure between cement and dentin was predominantly.
  
  
  
  The fiber post surface treatment appears have no Influence on bond strength between fiber post and root dentin.
  
  
  
  The tested fiber posts surface treatment appears do not Influence the fiber post bond behavior.
