1. Effect on adhesion of a nanocapsules-loaded adhesive system
Abstract This study aimed to evaluate the in situ degree of conversion, contact angle, and immediate and long-term bond strengths of a commercial primer and an experimental adhesive containing indomethacin- and triclosan-loaded nanocapsules (NCs). The indomethacin- and triclosan-loaded NCs, which promote anti-inflammatory and antibacterial effects through co

2. EFEITO DA FOTOATIVAÇÃO PROLONGADA DE ADESIVOS AUTOCONDICIONANTES NA ADESÃO À DENTINA / Effect of prolonged exposure time of one-step self-etching in dentinbonding
This study evaluated the effect of prolonged exposure times on immediate (IM) and 6-month (6M) adhesive properties: degree of conversion within hybrid layer (DC), silver nitrate uptake (SNU) and resin-dentin bond strenght (μTBS) for three one-step self-etch adhesive systems (Adper Easy Bond [EB], Clearfil S3 Bond [CS3] and Go [GO]).Ninety caries-free ex

3. Tensile bond strength of indirect composites luted with three new self-adhesive resin cements to dentin
OBJECTIVE: The aims of this study were to evaluate the tensile bond strengths between indirect composites and dentin of 3 recently developed self-adhesive resin cements and to determine mode of failure by SEM. MATERIAL AND METHODS: Exposed dentin surfaces of 70 mandibular third molars were used. Teeth were randomly divided into 7 groups: Group 1 (control gro

4. Análise da resistência da união de sistemas adesivos à dentina de dentes submetidos à radioterapia in vivo / Tensile bond strengths of adhesives systems to dentin irradiated teeth in vivo
Este estudo avaliou a resistência da união à dentina de dentes de pacientes que foram submetidos à radioterapia. Foram utilizados dezoito incisivos humanos extraídos de pacientes saudáveis (grupo controle) e dezoito incisivos de pacientes submetidos à radioterapia. As superfícies vestibulares de cada dente foram desgastadas para remover o esmalte e e

5. Influence of HEMA content on the mechanical and bonding properties of experimental HEMA-added glass ionomer cements
The purpose of this study was to determine the influence of incrementally added uncured HEMA in experimental HEMA-added glass ionomer cement (HAGICs) on the mechanical and shear bond strength (SBS) of these materials. Increasing contents of uncured HEMA (10-50 wt.%) were added to a commercial glass ionomer cement liquid (Fuji II, GC, Japan), and the compress

6. Influence of voids in the hybrid layer based on self-etching adhesive systems: a 3-D FE analysis
The presence of porosities at the dentin/adhesive interface has been observed with the use of new generation dentin bonding systems. These porosities tend to contradict the concept that etching and hybridization processes occur equally and simultaneously. Therefore, the aim of this study was to evaluate the micromechanical behavior of the hybrid layer (HL) w

7. Efeito do armazenamento em água na resistencia de União de diferenets abordagens de adesão a dentina / Effects of water storage on resin-dentin bond strengths formed by different bonding approaches
The purpose of this study was to evaluate the effects of water storage on resindentin bond strengths [μTBS] formed by different adhesive bonding approaches. A flat superficial dentin surface the 24 human third molars were exposed and polished to create a standardized smear layer. The teeth were randomly distributed into four different: total-etch 3 step

8. Effect of thermocycling on the tensile and shear bond strengths of three soft liners to a denture base resin
STATEMENT OF PROBLEM: In clinical practice, loss of adhesion between the silicone-based denture liner and the denture base resin is always an undesirable event that might cause loss of material softness, water sorption, bacterial colonization and functional failure of the prosthesis. PURPOSE: This study evaluated the effect of thermocycling on tensile and sh

9. Degradação de interfaces adesivas formadas após desmineralização e desproteinização da dentina / Long-term bond strengths of adhesive systems applied to etched and deproteinized dentin
The aim of this study was to evaluate the early and 12-month bond strengths of two adhesive systems (Single Bond-SB, 3MESPE and One Step-OS, Bisco) applied to demineralized dentin (WH) and demineralized/NaOCl-treated dentin (H). The adhesive interfaces were also micromorphologically evaluated by Scanning Electron Microscopy (SEM). Twenty flat dentin surfaces

10. Influence of glutaraldehyde priming on bond strengths of an experimental adhesive system applied to wet and dry dentin / Contribuição do glutaraldeído como componente de sistemas adesivos dentinários
Neste trabalho foram testadas as seguintes hipóteses nulas: 1) Não há diferença entre os valores de resistência de união entre resina restauradora e dentina quando uma solução aquosa de glutaraldeído é aplicada como primer dentinário antes do emprego do agente adesivo; 2) Não há diferença entre os valores de resistência de união, quando a apl

11. Tensile Bond Strength of Glass Ionomer Cements After Sonication / Influência do ultra-som na resistência adesiva à dentina de cimentos de ionômero de vidro
The aim of this study was to evaluate the influence of ultrasonic irradiation on the bond strength to dentin of glass-ionomer cements: conventional (Fuji II-a, Ketac-Fil Plus-b), resin-modified (Fuji II LC Improved-c, Photac-Fil Quick Aplicap-d) and high-viscosity (Ketac Molar-e). Fifty human molars were sectioned, embedded in epoxy resin with buccal or ling

12. "Influência do volume de adesivo e das ciclagens térmica e mecânica na resistência de união resina-dentina" / Influence of the adhesive volume, thermal and mechanical load cycling on the resin-dentin bond strength
Dentin bonding interfaces with increased capacity of stress dissipation are able to prevent failures due to polymerization contraction, thermal and mechanical stresses. This would be obtained by increasing adhesive layer thickness. The purpose of this study was to compare the resin-dentin microtensile bond strengths (BS) of two adhesive systems (AS) applied
