title: Push-out Bond Strength of Fiber Posts to Intraradicular Dentin Using Multimode Adhesive System.
abstract: BACKGROUND
  Because there is little information about bond strength of fiber posts cemented with a universal adhesive system (UAS) with different resin cements, the aim of this study was to compare the effect of different bonding strategies in the application of UASs on push-out bond strength of fiber posts to intraradicular dentin.
  
  
  METHODS
  Seventy-two single-rooted teeth were randomly divided into 6 groups: self-adhesive resin cement (SAC), dual-cure resin cement (DCC), UAS in the etch-and-rinse (E&R) mode and SAC (E&R + SAC), UAS in the self-etch (SE) mode and SAC (SE + SAC), UAS in the E&R mode and DCC (E&R + DCC), and UAS in the SE mode and DCC (SE + DCC). The push-out test was conducted at a crosshead speed of 0.5 mm/min. Data were analyzed with 2-way analysis of variance (P < .05).
  
  
  RESULTS
  Bond strength was significantly influenced by the adhesive strategies (P < .001). However, post space region did not have a significant effect on bond strength (P > .05).
  
  
  CONCLUSIONS
  ClearfilSA Luting SAC (Kuraray Noritake Dental Inc, New York, NY) cannot be used alone for fiber post adhesion; it needs an adhesive. Universal adhesive in the SE mode is suggested. When UAS is used for luting fiber posts, the type of cement does not have any effect on bond strength.
