multiple adhesive coating is a controversial topic, especially in primary dentition that should be clarified. we evaluated the effect of multiple consecutive adhesive resin coatings on the microshear bond strength (μsbs) of composite resin to primary tooth dentin utilizing a filled (adper single bond plus) and an unfilled (adper single bond) adhesive resin.thirty extracted primary canines were ...

objective: this study evaluated the effect of saliva contamination during bonding procedures without removing saliva on shear dentin bond strength of three adhesive generations when rubber dam isolation is not feasible. materials and methods: flat superficial dentin surfaces of seventy-two extracted human molars were randomly divided into three groups (a: scotch bond mp plus (sbmp), b: single b...

introdouction: esthetic demands of patients have led to the introduction of tooth-colored restorations wherecomposite resins are bonded to the enamel using acid etch techniques. total etch adhesion systems are still considered as the gold standard among bonding systems. however, clinicians have a tendency to use adhesive systems with simpler application procedures. the aim of the present study ...

statement of problem: following the increasing use of composites in restoring anterior and posterior teeth, problems due to its technique sensitivity have become a major concern. one of these problems is the possibility of contamination of dentin with saliva, blood and/or gingival fluid in different stages of bonding procedure, even with application of different methods of isolation. however, b...

PURPOSE The aim of this study was to evaluate the effect of metal primers on the bonding of dental alloys and veneer resin. Polyvinylpyrrolidone solution's tarnish effect on bonding strength was also investigated. MATERIALS AND METHODS Disk-shape metal specimens (diameter 8 mm, thickness 1.5 mm) were made from 3 kinds of alloy (Co-Cr, Ti and Au-Ag-Pd alloy) and divided into 4 groups per each ...

In complex cases of enamel fluorosis or enamel dys-mineralization, combined bleaching and micro-abrasion therapies may be advocated. The aim of the present study was to investigate the effect of combined in-office bleaching and micro-abrasion on the bond strength of two dental adhesives bonded to surface enamel. The interfacial micro-morphology of the involved surfaces was also studied by using...

INTRODUCTION Our objective was to determine the effects of intracoronal bleaching on the shear bond strength and failure side location of metallic brackets at 2 times (bleaching immediately before bonding and 30 days before bonding). METHODS Sixty freshly extracted mandibular incisors were randomly divided into 3 groups; each group contained 20 teeth. After finishing canal preparation and roo...

background: casein phosphopeptide-amorphous calcium phosphate (cpp-acp) is applied for remineralization of early caries lesions or tooth sensitivity conditions and may affect subsequent resin bonding. this in vitro study investigated the effect of cpp-acp on the shear bond strength of dental adhesives to enamel. materials and methods: sixty extracted human molar teeth were selected and randomly...
