Background he need of delimiting the bonding area on microshear bond strength (µSBS) test remains an unclear issue. In addition, there are different types tube to perform resin composite cylinders µSBS test. The aim this study was evaluate influence adhesive delimitation and type used build up specimens for testing systems, enamel dentin. Methods 120 bovine incisors were ground achieve flat buc...

OBJECTIVES To investigate the effects of adhesion technique using different contemporary adhesive systems on the cuspal movement in class II composite restorations in human premolar teeth. METHODS Human premolar teeth were prepared with class II cavities and then restored with composite and etch-and-rinse (Adper Scotchbond Multi Purpose and Adper Single Bond) or self-etch (Clearfil SE Bond an...

Background and aims. The aim of this study was to evaluate the effect of dilution and curing methods of an etch-and-rinse adhesive and a self-etching primer from the same manufacturer at early exposure time on cytotoxicity of primary human gingival fibroblasts. Materials and methods. Primary human gingival fibroblasts were exposed to different dilutions of Adper Single Bond (ASB) and Adper Prom...

PURPOSE This study was undertaken to investigate whether use of an adhesive penetration enhancer, dimethyl sulfoxide (DMSO), improves bond stability of fiber posts to root dentin using two two-step etch-and-rinse resin cements. MATERIALS AND METHODS Forty human maxillary central incisor roots were randomly divided into 4 groups after endodontic treatment and post space preparation, based on t...

OBJECTIVE The aim of this study was to evaluate the 5 year clinical dentin bonding effectiveness of two HEMA-free adhesives in Class V non-carious cervical lesions. MATERIAL AND METHODS A total of 169 Class V restorations were placed in 67 patients with a self-etching adhesive (G-Bond; 67), a 3-step HEMA and TEGDMA free etch-and-rinse (cfm; 51) and a control HEMA-containing etch-and-rinse adh...

The purpose of this study was to determine the elastic modulus of components at the resin-dentin interface with the use of an ultrasound device. Dentin slabs were obtained from freshly extracted bovine incisors shaped into a rectangular form. After demineralization, the dentin specimens were immersed in adhesives and polymerized. Adhesives were also polymerized and trimmed into the same shape a...

Abstract Objective Bonding to different dentin substrates influences resin composite restoration outcomes. This study investigated the influence of adhesion protocols on shear bond strength universal adhesive systems sound and artificial caries-affected (CAD). Materials Methods Occlusal enamel 80 premolars were wet grinded obtain flat midcoronal dentin. Specimens equally divided according subst...
