1. Translucency and color stability of resin composite and dental adhesives as modeling liquids – A one-year evaluation
Abstract The aim of this study is to evaluate the influence of modeling liquids on the translucency and color shade of resin composites (RCs) after one year of storage. RC specimens were prepared using either a conventional insertion technique (control; without modeling liquid) or a restorative dental modeling insertion technique (RDMIT) with dental adhesive

2. 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%

3. Síntesse de novos estabilizantes poliméricos do tipo poli(álcool vinilico-co-neo decanoato de vinila) para utilização na copolimerização em miniemulsão do acetato de vinila (VAc) com o neo-nonanoato de vinila (VEOVA-9) / Synthesis of new poly(vinyl alcohol-co-vinyl neodecanoate) based polymeric stabilizers, to be used in the miniemulsion copolymerizatin of vinyl acetate (VAc) with vinyl neononanoate (VEOVA-9).
Due to the technological and industrial importance of latexes stabilized with poly(vinyl alcohol)/PVA and the difficulties related to the emulsion polymerization of hydrophobic monomers and the use of PVA having a high degree of hydrolysis (>92%), the synthesis of new PVA based polymeric stabilizers for use in emulsion and miniemulsion polymerizations become

4. 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

5. 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

6. Avaliação da associação de clorexidina com etanol na durabilidade da adesão à dentina / Evaluation of the adjunctive use of chlorhexidine and ethanol on the durability of resin dentin bonds
Both adhesive and collagen degradation have been regarded as major causes of resin-dentin bonds failures over time. Complete infiltration of hydrophobic resins facilitated by ethanol, and the presence of MMPs inhibitors within the hybrid layer would build the ideal interface, resistant to hydrolysis and enzymatic activities. This study examined the benefits

7. Evaluation of bond strength and characterization of hybrid layer produced by an experimental adhesive based on hydrophobic methacrylate or dissolved in 10% and 30% ethanol, applied to ethanol-saturated dentin in a longevity study / Avaliação da resisténcia de união e caracterização da camada híbrida formada por adesivos experimentais a base de metacrilato hidrófobo ou solvatado em 10% e 30% de etanol, aplicados sobre dentina saturada com etanol em um estudo de longevi
The longevity of an adhesive interface is affected by the effects of hydrolytic degradation, which is associated with high water content in the dentin tissue. The hybridization of dentin with hydrophobic monomers in a water-free substrate could make the bond strength of these interfaces remain stable for an extended period of time. The aim of this study was

8. Avaliação da resistencia de união de sistemas adesivos e cimentos resinosos a dentina e aos compositos restauradores / Evaluation of bond strength of adhesive systems and resincements to dentin and restorative composites
The current concept of bonding to hard dental tissues is based on the infiltration of adhesive systems in enamel and dentin, in the so-called hybridization process. While the enamel bond has been considered a reliable procedure due to its uniform composition, bonding to dentin continues to present challenges. The objective of this study was to assess and dis

9. Evidence for van der Waals adhesion in gecko setae
Geckos have evolved one of the most versatile and effective adhesives known. The mechanism of dry adhesion in the millions of setae on the toes of geckos has been the focus of scientific study for over a century. We provide the first direct experimental evidence for dry adhesion of gecko setae by van der Waals forces, and reject the use of mechanisms relying

10. Response of microbial adhesives and biofilm matrix polymers to chemical treatments as determined by interference reflection microscopy and light section microscopy.
The polymers involved in the adhesion of Pseudomonas fluorescens H2S to solid surfaces were investigated to determine whether differences between cell surface adhesives and biofilm matrix polymers could be detected. Two optical techniques, i.e., interference reflection microscopy (IRM) and light section microscopy (LSM), were used to compare the responses of
