OBJECTIVES Different surface treatments may affect bonding performance of adhesive systems to dentin. This study evaluated the influence of different methods of surface treatment on adhesion of bonding agents to dentin. METHODS Dentin surfaces abraded with #600-grit SiC paper were used as control. Three methods of surface treatment (sono-abrasion, air-abrasion and Er:YAG laser irradiation) we...

The development of dentin bonding agents has revolutionized the field esthetic and restorative dentistry. Buonocore’s discovery on enamel acid-etching followed by description hybrid layer Nakabayashi et al are some major breakthroughs which responsible for changing paradigms in adhesive dentistry.On basis mode use,dental adhesives can be divided generations. Currently, challenges lie front rese...

PURPOSE There have been anecdotal reports of low bond strength with autocured resin composite materials, particularly when light-cured bonding agents that combine primer and adhesive in a 1-bottle preparation are used. The objective of this study was to determine if the mode of polymerization of the bonding agent influences the strength of the attachment of autocured resin composite luting ceme...

OBJECTIVE The aim of this study was to investigate the effect of aluminosilicate clay nanotubes (Halloysite, HNT) incorporated into the adhesive resin of a commercially available three-step etch and rinse bonding system (Adper Scotchbond Multi-Purpose/SBMP) on dentin bond strength, as well as the effect on several key physicochemical properties of the modified adhesive. METHODS Experimental a...

The relatlon between the bonding eMcacy ef the dentin adhesive and the physical change of the dentin after treatment with various dentin cleansers was investigated, The dentin surface was cleaned with one of the seven experimental dentin cleansers, 5, 10, 20, 30 and 40% of the phosphoric acid, neutralized O,5M EDTA solution (pH7.4) and 9.1% pyruvic acid containing 9,1% glycin, prior to the comb...
