The purpose of this experiment was to determine the hardness values of the hybrid layer and its surroundings through the continuous use of a microhardness measuring device. Black's Class V cavities were prepared in nine dog teeth. The cavities were divided into four groups according to the dentin adhesive system applied. The adhesive systems were: "Bond One System", "Liner Bond II sigma System"...

The wetness of dentin surfaces, the presence of pulpal pressure, and the thickness of dentin are extremely important variables during bonding procedures, especially when testing bond strength of adhesive materials in vitro with the intention of simulating in vivo conditions. The ultimate goal of a bonded restoration is to attain an intimate adaptation of the restorative material with the dental...

BACKGROUND The study aims to investigate the effect of incorporation of sepiolite nanoparticles on the microtensile bond strength of an experimental dentin bonding to the human dentin. MATERIAL AND METHODS The sepiolite nanoparticles were incorporated into an experimental methacrylate-based dentin bonding system in concentrations of 0.0, 0.2, 1.0, 2.0, and 5.0 weight percents. The specimens w...

Early history of dentin bonding Attempts to develop an adhesive system which bonds acrylic resins to the tooth structure started in the early 1950s. In 1949, an adhesive system capable of bonding acrylic resin to the tooth structure was invented by Hagger; it was composed of glycerophosphoric acid dimethacrylate (GPDM) and sulfinic acid as the catalyst. In his patent, shear bond strengths of ac...

The acid-etch technique for bonding composite resins to enamel has revolutionized the practice of pediatric restorative dentistry. Although bonding resins to dentin has proved to be a difficult challenge, ongoing advances have improved the reliability and predictability of dentinal adhesion. The purpose of this paper is to review the subject of dentin bonding; its development, current status, a...

BACKGROUND In response to concerns of bacterial biofilm colonization of dental unit waterlines, a wide range of commercial intermittent and continuous chemical treatments for dental unit waterlines have been developed and marketed. There has been little research on the possible effect of continuous chemical treatment regimens on dentin-bonding agents. The authors evaluate the effect of four pro...

OBJECTIVE The effect of dentin desensitizer Systemp on the shear bond strength of composite resin to dentin using three different bonding agents, i.e., Prime & Bond NT, Xeno V+, and Futurabond DC were evaluated. MATERIALS AND METHODS Sixty recently extracted human premolars were divided into six groups of ten teeth each. The superficial dentin was etched with 37% phosphoric acid. In Groups I,...

Objective: The objective of this mini review is to evaluate the age-related changes in dentin and its effect on bonding.Background: Bonding poses a great challenge which can be attributed multifarious including factors such as high organic content dentin, presence dentinal tubules, continuously moist environment due fluid permeability intratubular pressure. bonding becomes more challenging with...
