The purpose of this study was to evaluate the bonding ability of four representative dentin-adhesive systems by applying the micro-shear bond strength (μ-SBS) test method and to evaluate the influence of adhesive area limitation on the bond strength. Two different adhesive application methods were used in the μ-SBS test (with and without adhesives area limitation), and four representative adhes...

Does the dryness of tooth surface influence the bonding efficacy of self-adhesive resin cement? I would like to know how much I should dry the tooth surface for better adhesion of self-adhesive resin cement. Q Self-adhesive resin cements are designed to adhere to the tooth substrate without a separate adhesive or etchant. The first commercial product, RelyX Unicem, was launched in 2002 and gain...

INTRODUCTION Disinfection of dentin surfaces is desirable so long as it does not interfere with subsequent bonding of adhesive resins. OBJECTIVE To test the null hypothesis that bond strengths to dentin are not affected by previous application of an iodine disinfecting solution. MATERIALS AND METHODS Twenty-four extracted non-carious molars were selected. Occlusal enamel was removed produci...

The use of self-adhesive resin cements is accomplished by a simple clinical step, in which the simultaneous demineralization/infiltration of the bonding substrate takes place. However, the self-adhesive resin cements have lower bond strength than conventional resin cements that rely on the application of etch-and-rinse adhesive systems. In order to increase the bond strength of the self-adhesiv...

Since the acid-etch technique for bonding to the tooth substrate had been introduced, adhesive dentistry evolved rapidly due to two main reasons; esthetic satisfaction and minimal invasiveness. Some retrospective clinical studies have showed the favorable durability of resin restoration over 10 years. However, the majority of bonded restorations are disadvantaged by their early failure during s...

BACKGROUND Photochemical tissue bonding (PTB) is a promising sutureless technique for tissue repair. PTB is often achieved by applying a solution of rose bengal (RB) between two tissue edges, which are irradiated by a green laser to crosslink collagen fibers with minimal heat production. In this study, RB has been incorporated in chitosan films to create a novel tissue adhesive that is laser-ac...

Despite the biodegradability, non-toxicity, and renewability, commercially available soy protein-based adhesives still have not been widely adopted by industry, partially due to their disappointing performances, i.e., low glue strength in the dry state and no glue strength in the wet state. In this study, biomimetic soy protein/CaCO(3) hybrid wood glue was devised and an attempt made to improve...

Achieving weight reduction in lightweight structural and protection applications, multi-material assemblies are being proposed in several applications ranging from tactical wheeled vehicles, rotorcraft, and munitions. Adhesive bonding of dissimilar materials found in these systems is a critical technology in the production of lightweight energy absorbing structures. The design and control of th...

introduction in this study, we have investigated the effect of using phosphoric acid on bonding efficacy of an all-in-one adhesive system, after salivary contamination of dentin. methods and materials eighty-four extracted human molars were prepared for their superficial dentins to be exposed. the molars separated into 7 groups. group 1 specimens were not contaminated. in groups 2-4, samples we...
