Localized Mechanics of Dentin Self-etching Adhesive System
The bond strength of composite resins (CRs) to dentin is influenced by the interfacial microstructure of the hybrid layer (HL) and the resin tags (TAG). The contemporary self-etching primer adhesive systems overcame the inconvenient of the etch-and-rinse protocol. Studies, however, have demonstrated that HL thickness and TAG length vary according to the wetting time and additional use of acid-e...
متن کاملMicroleakage and Resin-to-Dentin Interface Morphology of Pre-Etching versus Self-Etching Adhesive Systems
The purpose of this study was to compare the microleakage and tissue-adhesive interface morphology from Class V restorations using different systems of dentin adhesives. Class V cavities were prepared on buccal surfaces of 27 extracted caries-free molars and premolars. Teeth were randomly assigned to one of three groups: (1) Prime & Bond NT, a 5(th) generation system using an initial step of to...
متن کاملEffect of the self etching dentin primers on the bonding efficacy of a dentin adhesive.
The efficacy of marketed and experimental self etching dentin primers which contained dicarboxylic acids or their esterified salts diluted in 35% hydroxyethylmethacrylate (HEMA) solution were studied by measuring the wall-to-wall polymerization contraction of the light curing composite in the cylindrical dentin cavity and the tensile bond strength to the flat dentin surface. In both of the meas...
متن کاملInfluence of additional etching on shear bond strength of self-etching adhesive system to enamel
Recently, self-etching adhesive system has been introduced to simplify the clinical bonding procedures. It is less acidic compared to the phosphoric acid, thus there is doubt whether this system has enough bond strength to enamel. The purpose of this study was to investigate the influence of additional etching on the adhesion of resin composite to enamel. Ninety extracted bovine permanent anter...
متن کاملPre-treating dentin with chlorhexadine and CPP-ACP: self-etching and universal adhesive systems
Objective: The aim of the present study was to compare the effect of pre-treating dentin with chlorhexidine, at concentrations of 0.2% and 2%, and remineralizing paste containing CPP-ACP (MI Paste - GC) on the bond strength of adhesive systems. Material and methods: In total, 80 slides of dentin were used. These slides were 2 mm thick and were obtained from bovine incisors. Standard cavities we...
