1. 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

2. 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

3. Effect of a desensitizing dentifrice on the bond strength of different adhesive systems
AIM: This in vitro study evaluated the effect of using a dental hypersensitivity treatment on the bond strength to dentin of etch-and-rinse and self-etching simplified adhesive systems. METHODS: 40 healthy molars were used. The crowns of teeth were removed at the dentinoenamel junction, and remaining roots were sectioned in the mesiodistal direction along th

4. Análise de sistemas de fixação resinosos : por meio de nanoinfiltração, microdureza e microcisalhamento / Analisys of resin luting systems through nanoleakage
During the cementing indirect restorations procedure using resin luting systems, polymerization is essential for an effective clinical outcome of success. The aim of this in vitro study was to evaluate the Knoop hardness (KHN), microshear bond strength (MSBS) and nanoleakage pattern of resin cements and flowable resin to dental enamel. Ninety-two enamel bovi

6. Effect of an additional hydrophilic versus hydrophobic coat on the quality of dentinal sealing provided by two-step etchand-rinse adhesives
OBJECTIVE: To test the hypothesis that the quality of the dentinal sealing provided by two-step etch-and-rinse adhesives cannot be altered by the addition of an extra layer of the respective adhesive or the application of a more hydrophobic, non-solvated resin. MATERIAL AND METHODS: full-crown preparations were acid-etched with phosphoric acid for 15 s and b

7. Avaliação da qualidade da união resina composta-dentina obtida pelo emprego de materiais/tecnicas que visam minimizar os efeitos da umidade dentinaria sobre a longevidade das restaurações adesivas / Evaluation of the quality of resin/dentin bonds obtained by using techniques/materiais that intent to minimize the effect of dentin wetness on the longevity of adhesive restorations
The general aim of this study was to evaluate materials and techniques that are thought to increase the longevity of adhesive restorations. The specific aims of this study were: 1) to test whether the application of an extra layer of the respective adhesive or the application of a hydrophobic, non-solvated bonding agent would interfere on the permeability of

8. Influencia do meio e tempo de armazenamento na resistencia a microtração de sistemas adesivos / Influence of time and storage medium in the microtensile bond strength of adhesive systems
The purpose of this study was to evaluate "in vitro" the microtensile bond strength of two adhesive systems applied to the dentin as a function of time and storage medium, as well as to illustrate, through Scanning Electron Microscope (SEM) images, the nanoleakage of the hybrid layer, which had its constituents evaluated by microanalysis (EDS). Eighty recent

9. Nanoleakage phenomenon on deproteinized human dentin
OBJECTIVE: The purpose of this study was to evaluate the influence of dentin deproteinization on the nanoleakage phenomenon. MATERIAL AND METHODS: Class V cavities were prepared in 12 human molars with cervical margins located in dentin. The cavities were assigned to 2 groups (n=6) according to dentin treatment: Group I - dentin treated in accordance with th
