2. Do Irrigation Solutions Influence the Bond Interface Between Glass Fiber Posts and Dentin?
Resumo O objetivo deste trabalho foi avaliar a resistência de união e permeabilidade da interface de pinos de fibra de vidro nos diferentes terços da dentina intrarradicular (cervical, médio e apical) submetidos a diferentes agentes irrigantes. Noventa dentes unirradiculares humanos foram submetidos ao tratamento endodôntico e foram divididos em cinco g

3. Light curing resin cements containing iodonium salts promote suitable apical bonding of posts to radicular dentin
Abstract The aim of this study was to analyze the efficiency of experimental light-curing resin cements (ERCs) with a ternary photo-initiator system containing diphenyliodonium hexafluorphosphate (DPI) and different amines on retention of glass-fiber posts to dentin (GFP). ERCs formulations: a 1:1 mass ratio of 2,2-bis[4-(2-hydroxy-3-methacryloxypropoxy)phen

4. Influence of Zingiber officinale Extract on Push-Out Bond Strength of Glass-Fiber Post
Resumo O objetivo deste estudo foi avaliar in vitro a influência do extrato de gengibre 20% na resistência adesiva de pinos de fibra de vidro cimentados com cimentos resinosos convencional ou autocondicionantes. Quarenta e oito raízes bovinas foram padronizadas (17±0.5mm) e aleatoriamente divididas em dois grupos (n=24), de acordo com o irrigante utiliza

5. Effects of the application techniques of self-adhesive resin cements on the interfacial integrity and bond strength of fiber posts to dentin
ABSTRACT Objective: To evaluate the influence of an application technique of a glass-fiber post using self-adhesive resin cements on the push-out bond strength and the presence of bubbles in the root thirds. The cements were either applied according to the manufacturer's instruction or using a commercial delivering system (Centrix), at which the cement past

6. Acid Etching and Surface Coating of Glass-Fiber Posts: Bond Strength and Interface Analysis
Resumo O objetivo deste estudo foi avaliar o efeito resistência de união de uma resina composta para pinos de fibra de vidro (PFV) tratados ou não com ácido fosfórico, agente de união (silano) e adesivo. PFVs foram condicionados ou não com ácido fosfórico 37% e receberam aplicação de diferentes materiais: um agente de união, um adesivo, ou ambos.

8. Influence of antimicrobial solutions in the decontamination and adhesion of glass-fiber posts to root canals
AbstractObjective This study evaluated the effect of root canal disinfectants on the elimination of bacteria from the root canals, as well as their effect on glass-fiber posts bond strength.Material and Methods Fifty-three endodontically treated root canals had post spaces of 11 mm in length prepared and contaminated with E. faecalis. For CFU/ml analysis, ei

9. A systematic review of factors associated with the retention of glass fiber posts
This study aimed to identify factors that can affect the retention of glass fiber posts to intra-radicular dentin based on in vitro studies that compared the bond strength (BS) of GFPs cemented with resin cements. Searches were carried out in PubMed and Scopus until December 2013. Bond strength values and variables as type of tooth, presence of endodontic tr

10. Immediate and delayed photoactivation of self-adhesive resin cements and retention of glass-fiber posts
The aim of this study was to evaluate the effect of immediate and delayed photoactivation of self-adhesive resin cements (SARCs) on the retention of glass-fiber posts luted into root canals. Bovine incisors were endodontically treated, and post holes of 9 mm in depth were prepared. Fiber posts were luted using one of two SARCs, BisCem(r) (Bisco Inc., Schaumb

11. Chemical cleaning agents and bonding to glass-fiber posts
The influence of chemical cleaning agents on the bond strength between resin cement and glass-fiber posts was investigated. The treatments included 10% hydrofluoric acid, 35% phosphoric acid, 50% hydrogen peroxide, acetone, dichloromethane, ethanol, isopropanol, and tetrahydrofuran. Flat glass-fiber epoxy substrates were exposed to the cleaners for 60 s. Res

12. Intra-radicular dentin treatments and retention of fiber posts with self-adhesive resin cements
The aim of this study was to evaluate the effect of treating intraradicular dentin with irrigating solutions on the retention of glass-fiber posts luted with self-adhesive resin cement. Bovine incisors were endodontically treated, and 9-mm-deep postholes were prepared. Before inserting the cement, the root canals were irrigated with various solutions: 11.5%
