title: Effect of adhesive systems and surface treatment of methacrylate resin-based fiber posts on post-resin-dentin bonds.
abstract: OBJECTIVE
  To evaluate the effect of different fiber post surface treatments on bond strength.
  
  
  METHODS
  Extracted endodontically-treated premolars were prepared for the cementation of a methacrylate resin-based fiber post (FRC Postec). The posts received one of the three surface pre-treatments: silane application; hydrofluoric acid-etching and silane application or no treatment. A light-cured composite was used with one of the three dentin adhesives for luting: Single Bond; Clearfil Photo Bond and Clearfil New Bond, followed by a light-cured composite core build-up. Specimens were serially sliced into 0.8 x 0.8 mm-thick beams and loaded in tension until failure.
  
  
  RESULTS
  Significant differences in bond strengths were recorded among the dentin adhesives (P< 0.05). However, post pre-treatment did not affect the bonding efficacy of the adhesives except for Clearfil New Bond.
