Recently, one-bottle resins adhesives have been developed to reduce the number of clinical steps of resin application. They are now widely used in clinical dental practice. However, little is known regarding the detailed mechanism of bond degradation. Therefore, this study evaluated the durability of one-bottle resin adhesives using long-term water storage testing. Resin-dentin bonded specimens...

This paper describes a research program that was conducted in two phases to study the behavior of a high modulus CFRP system for strengthening steel structures. The first phase of the research consisted of an experimental program and finite element analysis to study the bond characteristics of the system. The findings indicate that a reverse tapered plate end detail can effectively increase the...

The purpose of this study was to evaluate the effects of functional monomers contained in the primers, as well as alumina particle abrasion on bonding between stainless steel and acrylic resin. SUS XM27 steel was primed with one of the following materials; Alloy Primer, Estenia Opaque Primer, M. L. Primer, and Super-Bond Liquid. Steel disks were either ground flat or alumina-blasted, primed wit...

The technique of strengthening steel structures with Carbon Fibre Reinforced Polymer (CFRP) has attracted growing attention in research field and in practice and its environmental durability is of high importance. This paper describes an investigation on the bond characteristics between high modulus CFRP sheet and steel plates under elevated temperature exposures. Tensile tests were carried out...

PURPOSE The porcelain fused to gold has been widely used as a restoration both with the natural esthetics of the porcelain and durability and marginal fit of metal casting. However, recently, due to the continuous rise in the price of gold, an interest towards materials to replace gold alloy is getting higher. This study compared the bond strength of porcelain to millingable palladium-silver (P...

Bridges with reinforeerneut corrosion problems are now under careful inspection in Taiwan. Costly maintenance programs are underway and raising S"erious safety concem. There are various engineering solutions to salt-induced corrosion. Among them epoxycoated reinforcing bars, commonly referred to as rebar, are frequently used in marine environment and other areas due to its durability, reasonabl...

The present study evaluated the durability of bond strength between zirconia and 3 different resin cements. Thirty stabilized tetragonal zirconium-dioxide blocks were duplicated in dual-curing resin core build-up material specimens. Resin blocks were randomly luted to zirconium surfaces using 1) Clearfil Esthetic Cement (CLF), 2) RelyX Unicem Aplicap (RELX), or 3) Multilink Automix (MLA). After...

statement of the problem: self-etch adhesives can activate matrix metalloproteinase (mmp) which hydrolyzes organic matrix of demineralized dentin. epigallocatechin gallate (egcg), especially found in green tea, could inhibit the activation of mmp. purpose: the aim of this study was to evaluate the effect of adding epigallocatechin gallate (egcg) into two types of adhesives on dentin bond streng...

BACKGROUND With the increase in demand for cosmetics and esthetics, resin composite restorations and all-ceramic restorations have become an important treatment alternative. Taking into consideration the large number of prosthodontic and adhesive resins currently available, the strength and durability of these materials needs to be evaluated. This laboratory study presents the shear bond streng...
