Heat treatment-improved bond strength of resin cement to lithium disilicate dental glass-ceramic
(2016-06-01)
This study investigated the influence of different hydrofluoric acid (HF) concentrations and heat treatments applied to a lithium disilicate dental glass-ceramic (EMX) on surface morphology and micro-shear bond strength ...
Ribbed glass fiber reinforced plastic rebar embedded in concrete – an experimental study
(Sage Publications, 2013-08)
The experimental program developed in this work aims at investigating the bond behavior of glass fiber reinforced plastic embedded in concrete. Different types of surface treatment were applied to the smooth rods in order ...

Pré tratamento dentinário influência do condicionamento ácido, irradiação laser e hipermineralização na resistência ao cisalhamento de sistema adesivo multi uso
(Universidade Estadual Paulista (Unesp), 1997-06-17)
The disadvantages generated by the acid etching of the dentin, such as an increase in its permeability, in the surface moisture and in the potential to denature the external dentinal collagen, the formation of a fragility ...
Water-based adhesive formulations for rubber to metal bonding developed by statistical design of experiments
(Elsevier Ltd, 2017-03-01)
Waterborne adhesives for rubber to metal bonding have been available since 1990. However, published information about their formulation has been limited, as proprietary restrictions are exercised by companies. As a ...

Effect of curing time on the bond strength of a bracket-bonding system cured with a light-emitting diode or plasma arc light
(European Orthodontic SocietyPorto Alegre, 2011)
The purpose of this study was to assess the influence of two light units, a light-emitting diode (LED) and a plasma arc light (PAC), on the shear bond strength (SBS) of brackets bonded to enamel. Ninety bovine teeth were ...
