1. Microtensile bond strength of root canal dentin treated with adhesive and fiber-reinforced post systems
Abstract Nowadays, demand for esthetic restorations has risen considerably; thus, nonmetal esthetic posts made of either high-strength ceramics or reinforced resins, such as fiber-reinforced resin posts, have become more and more popular. Important characteristics of fiber-reinforced posts involve a modulus of elasticity similar to dentin and their ability t

2. 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

3. 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

4. Effect of different endodontic sealers on push-out bond strength of fiber posts
Despite the increasing demand for fiber-reinforced composite (FRC) posts, their bonding to root canals is still subject to debate. Endodontic sealers may affect the bond strength between fiber posts and root canal dentin. Aim: To compare the effects of different sealers on fiber post bond strength. Methods: Sixty teeth were divided into 4 groups according

5. A titration model for evaluating calcium hydroxide removal techniques
Objective Calcium hydroxide (Ca(OH)2) has been used in endodontics as an intracanal medicament due to its antimicrobial effects and its ability to inactivate bacterial endotoxin. The inability to totally remove this intracanal medicament from the root canal system, however, may interfere with the setting of eugenol-based sealers or inhibit bonding of resin

6. Influência da limpeza mecânica com e sem o uso do microscópio operatório na resistência adesiva intrarradicular / Influence of mechanical cleaning with and without the use of the operating microscope in intraradicular adhesive strength
In endodontic treatment, there is an imperative need to restore the tooth, reestablishing its functions, since there is always a risk of recontamination of the root canal system and fractures. These risks are higher when there is loss of dental structure, requiring intraradicular posts to hold the restoration procedures in place. For the definitive and immed

7. Push-out bond strength and SEM evaluation of a new bonding approach into the root canal
OBJECTIVE: This study evaluated the performance of different adhesive systems in fiber post placement aiming to clarify the influence of different hydrophobic experimental blend adhesives, and of one commercially available adhesive on the frictional retention during a luting procedure. MATERIAL AND METHODS: One luting agent (70 Wt% BisGMA, 28.5% TEGDMA; 1.5%

8. Efeito da técnica úmida simplificada de adesão com etanol na cimentação intraradicular de pinos de fibra / Push-out bond strength and SEM evaluation of new bonding approach into the root canal
Este estudo avaliou a resistência ao deslocamento vertical push-out de pinos de fibra de vidro cimentados à dentina intra-radicular utilizando uma resina fluida padrão como agente cimentante em combinação com um adesivo dentinário experimental e um adesivo disponível comercialmente. 20 pré-molares unirradiculares humanos foram previamente extraídos

9. Post surface conditioning: effect on bond strength to composites after aging and on flexural strength of fiber posts. / CONDICIONAMENTO DA SUPERFÍCIE DE PINOS DE FIBRA DE VIDRO: INFLUÊNCIA NA RESISTÊNCIA ADESIVA APÓS CICLAGEM MECÂNICA E NA RESISTÊNCIA À FLEXÃO DOS PINOS
Aim: To evaluate the bond strength between glass fiber post and intrarradicular dentin or core composite resin after several post surface treatments, and the effect of surface treatments on posts flexural strength. Material and methods: The following post surface treatments were evaluated: G1- no conditioning; G2- cleaning with alcohol (AL); G3- AL + silane

10. : Evaluation of the sealing provided by resin-based endodontic filling materials and analysis of the expression of metalloproteinases in human and bovine dentin matrix / Avaliação do selamento do conduto radicular por materiais obturadores endodonticos resinosos e analise da expressão de metaloproteinases na matriz dentinaria humana e bovina
Restorative strategies involving dentin bonding have been increasingly applied to endodontics. The first study evaluated the immediate and long-term sealing ability of adhesive versus conventional endodontic filling materials and investigated the influence of a coronal seal on leakage rates. After chemo-mechanical preparation/irrigation, human roots were fil

11. Influence of different adhesive systems on the pull-out bond strength of glass fiber posts
This in vitro study evaluated the tensile bond strength of glass fiber posts (Reforpost - Angelus-Brazil) cemented to root dentin with a resin cement (RelyX ARC - 3M/ESPE) associated with two different adhesive systems (Adper Single Bond - 3M/ESPE and Adper Scotchbond Multi Purpose (MP) Plus - 3M/ESPE), using the pull-out test. Twenty single-rooted human tee

12. AvaliaÃÃo da resistÃncia de uniÃo da interface adesiva de pinos de fibra de vidro e a dentina radicular / Bond strength at the adhesive interface of fiber glass posts and root dentin
The aim of this study was to assess the bond strength at the adhesive interface of fiber glass posts and root dentin, in three regions of the canal, fixed with three cementation systems. Twenty-four healthy human teeth, recently extracted for orthodontic or periodontal reasons, had their crowns removed at the cement-enamel junction with a diamond disk, under
