Mild self-etch adhesives demineralize dentin only partially, leaving hydroxyapatite around collagen within a submicron hybrid layer. We hypothesized that this residual may serve as receptor for chemical interaction with the functional monomer and, subsequently, contribute to adhesive performance in addition micro-mechanical hybridization. therefore chemically characterized of 3 monomers synthetic hydroxyapatite, using x-ray photoelectron spectroscopy and atomic absorption spectrophotometry....
Resin-dentin bonds degrade over time. The objective of this study was to evaluate the influence variables like hybridization effectiveness and diffusion/elution interface components on degradation. Hypotheses tested were: (1) There is no difference in degradation time between two- three-step total-etch adhesives; (2) a composite-enamel bond protects adjacent composite-dentin against micro-tensile strength (μTBS) dentin 2 adhesives compared with that two-step after 4 years storage water....
One-step adhesives bond less effectively to enamel/dentin than do their multi-step versions. To investigate whether this might be due phase separation between adhesive ingredients, we characterized the interaction of 5 experimental and 3 commercial self-etch with dentin using transmission electron microscopy. All were examined for homogeneity by light Bonding effectiveness was determined use a micro-tensile bond-strength protocol. The lower strength one-step associated light-microscopic...
Functional monomers chemically interact with hydroxyapatite that remains within submicron hybrid layers produced by mild self-etch adhesives. The functional monomer 10-MDP interacts most intensively hydroxyapatite, and its calcium salt appeared hydrolytically stable, as compared 4-MET phenyl-P. We investigated the hypothesis additional chemical interaction of adhesives improves bond stability. micro-tensile strength (μTBS) 10-MDP-based adhesive did not decrease significantly after 100,000...
Functional monomers in adhesive systems can improve bonding by enhancing wetting and demineralization, chemical to calcium. This study tested the hypothesis that small changes structure of functional may their effectiveness. Three experimental phosphonate (HAEPA, EAEPA, MAEPA), with slightly different structures, 10-MDP (control) were evaluated. Adhesive performance was determined terms microtensile bond strength 4 cements differed only for monomer. Based on Adhesion-Decalcification concept,...
Adhesive procedures activate dentin-associated matrix metalloproteinases (MMPs), and so iatrogenically initiate bond degradation. We hypothesized that adding MMP inhibitors to adhesive primers may prevent this endogenous enzymatic degradation, thereby improving durability. A non-specific inhibitor (chlorhexidine) a MMP-2/9-specific (SB-3CT) were admixed the of an etch & rinse self-etch adhesive, both considered as gold-standard adhesives within their respective categories. For dentin...
The aim of this in vivo study was to evaluate the clinical performance porcelain veneers after 5 and 10 years service.A single operator placed laminates on 87 maxillary anterior teeth 25 patients. All restorations were recalled at 93% years. Clinical assessed terms esthetics, marginal integrity, retention, microleakage, caries recurrence, fracture, vitality, patient satisfaction. Failures recorded either as "clinically unacceptable but repairable" or with replacement needed".Porcelain...
