BACKGROUND Evaluate the influence of different hybridization bonding techniques of a self-adhesive resin cement. MATERIAL AND METHODS 30 human health molars were divided into six groups (n=10). The specimens received three longitudinal sections, allowing insertion of central cuts in PVC matrices. Each group received a different dentin pretreatment according to the manufacturer's recommendatio...

The aim of this study was to evaluate the effect of desensitizing agents on the bond strength of different adhesive systems condition and rinse and self-etching to dentin through microshear. Sixty dentin fragments were used, obtained from the buccal and lingual surfaces of molars third molars, which were distributed in groups (n = 12) according to desensitizing treatment (control no treatment; ...

background and aims. er:yag laser irradiation has been claimed to improve the adhesive properties of dentin; therefore, it has been proposed as an alternative to acid etching. the aim of this in vitro study was to investigate the shear bond strength of an etch-and-rinse adhesive system to dentin surfaces following er:yag laser and/or phosphoric acid etching. materials and methods. the roots of ...

statement of problem: recently, it has been proposed that different adhesive materials can be used for direct pulp capping. previous studies have demonstrated that multi steps dentin adhesives could form reparative dentin similar to calcium hydroxide (ch). purpose: the aim of this study was to evaluate the histological pulp response of ninety mechanically exposed cat pulps to two adhesive resin...

The relation between the bonding efficacy of 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 0.5 M EDTA solution (pH 7.4) and 9.1% pyruvic acid containing 9.1% glycine, prior to the...

OBJECTIVES The present study was conducted to evaluate the effect of nanosized aluminum trioxide (Al2O3) particles when added to the Nano-Bond adhesive system and its effect on the microshear bond strength of nanocomposite resin to dentin. MATERIALS AND METHODS A newly developed adhesive (Nano-Bond) and one type of light-cured resin restorative material (nanocomposite resin) were used in this...

The purpose of this study was in vitro evaluation and comparison of the adhesion of self-etch (SE) adhesive systems applied on normal and sclerotic dentin. For this study, Class 5 cavities were prepared on sound teeth as well as on teeth with sclerotic dentin. They were then restored by means of the SE 2-step OptiBond XTR (Kerr) and SE 1-step Bond Force (Tokuyama Dental) adhesive systems, as we...

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...

background and aims. the aim was to evaluate the effect of casein phosphopeptide–amorphous calcium phosphate (cpp-acp) on microtensile bond strength (µtbs) to carious affected dentin (cad) using etch-and-rinse and self-etch adhesive systems. materials and methods. the occlusal surface of 32 human molars with moderate occlusal caries was removed. infected dentin was removed until reaching cad an...

To evaluate the effect of a dentin adhesive on sclerotic dentin, contraction gap width and shear bond strength were measured. Dentin cavity wall was pretreated with an experimental dentin bonding system with and without a dentin primer, or with a commercial dentin bonding system. In the experimental dentin bonding groups, contraction gap width of sclerotic dentin was significantly smaller than ...
