چکیده
Fiber reinforced composite (FRC) posts are commonly used by clinicians in post-endodontic restorations, mostly due to their favorable physical properties, i.e. the modulus of elasticity close to that of dentin (1). Yet, clinical failures involving endodontically treated teeth reconstructed with FRC posts could occur and are mainly attributed to cementation flaws (2). The design and composition of different FRC posts may affect their bonding capacity and restoration quality (3). Prefabricated FRC posts exhibit a highly cross-linked polymer matrix with high degree of conversion, which makes it difficult to bond the post to composite resin cement and tooth structure (4). Uvod

Comparison of the Bond Strength of Fiber-Reinforced Composite (FRC) Posts to Radicular Dentin Using Different Adhesive Cement: an in-vitro study
Introduction: Retention of fiber reinforced composite posts depends on the bond strength between post and cement, and cement and root dentin. The aim of this study is to evaluate the bond strength of one type of fiber post to radicular dentin with different adhesive cements. Materials and Methods: Crowns of 44 caries-free, human premolar were removed 2 mm below the CEJ and the roots were endod...

Background and Aims: In endodontically treated teeth, the fiber posts are used to retain a core restoration. The purpose of this study was to evaluate the effect of different resin cements on the bond strength of fiber reinforced composite posts to root canal dentin, and comparing the bond strength in different sections of root. Materials and Methods: In this in-vitro experimental study, 48 ex...
متن کاملInfluence of root dentin treatment on the push-out bond strength of fibre-reinforced posts
This study evaluates the influence of root dentin treatment with NaOCl alone and combined with EDTA, with and without ultrasound activation, on the push-out bond strength (BS) of fiber-reinforced posts in weakened roots, cemented with RelyX or Panavia. The root canals of 42 maxillary canines were instrumented with Reciproc and 2.5% NaOCl. In the coronal 12mm of all canals, experimental weakenin...
متن کاملEffect of Intracanal Dentin Conditioning with Xylene, Phosphoric Acid and Chlorhexidine on Bond Strength to Glass Fiber Post with Self-Adhesive Cement
Background and Aim: Debonding is the most commonly encountered failure in teeth restored with fiber posts that mainly occurs at the weakest interface (dentin-cement interface). Thus, reinforcement of this interface is mandatory. The aim of this study was to evaluate the effect of different root dentin surface treatments after post space preparation on bond strength of fiber posts cemented with ...
متن کاملBond strength of fiber posts to weakened roots after resin restoration with different light-curing times.
INTRODUCTION This study evaluated the bond strength of translucent fiber posts to experimentally weakened radicular dentin restored with composite resin and polymerized with different light-exposure time. METHODS Roots of 60 maxillary incisors were used. Twenty-four hours after obturation, the filling materials of root canals were removed to a depth of 12 mm, and 4 groups were randomly formed...
