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 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 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 کاملRegional bond strength of four self-etching primer/adhesive systems to root canal dentin.
The purpose of this study was to evaluate the regional bond strength of a dual-cure resin core material to root canal dentin using four self-etching primer/adhesive systems. Post spaces were prepared in extracted premolars, and their root canal dentin was treated with one of the following self-etching primer/adhesive systems: ED Primer II and Clearfil Photobond, photo-cure/dual-cure systems of ...
متن کاملBond strength of composite to dentin and enamel using self-etching adhesive systems.
To determine the shear bond strength of 10 self-etching adhesive systems to dentin and enamel, flat bonding sites were prepared on 216 extracted human molar teeth, using 600-grit silicon carbide paper to expose dentin or enamel. Following the application of each adhesive system, bonded assemblies of Spectrum TPH were prepared using a gelatin capsule matrix (n = 24). After 24 hours of storage in...
