Abstract In most bonding processes, an adhesive is applied to a substrate in specific pattern before the second subsequently pressed against it. During this, flows such way that, ideally, it completely fills joint. practice, however, areas with entrapped air frequently remain bonded layer. Within scope of research project, these are systematically analyzed order identify optimal initial applica...

Introduction: Simultaneous etching of enamel and dentin using the novel generation of adhesive systems with contracted operational steps, has shown a good clinical efficacy. The aim of this study was to evaluate the microleakage of composite restorations using the V and VII generations of adhesive systems on primary teeth. Methods: This study was performed on 45 human intact extracted primar...

Background: many of the problems and composite filling failures are due to dentists' inadequate and passing acquaintance with bonding principles. The aim of this study is to assess dentists' acquaintance with the bonding principles and different adhesive application that are going to be used in educational programs. Methods: in this descriptive and cross-sectional study, a valid and reliable qu...

This study is concerned with pen-joint and interjoint coordination in handwriting. In particular, it focuses on the stability of coordination as a means to find the locus of coordination control in the arm-pen effector system. Twelve subjects generated loop sequences of varying length at various positions on the baseline of writing. Joint excursions and pen-tip displacements were recorded by me...

STATEMENT OF THE PROBLEM Sufficient adhesion between silorane/methacrylate-based composites and methacrylate impregnated glass fiber increases the benefits of fibers and enhances the mechanical and clinical performance of both composites. PURPOSE The aim of this study was to evaluate the compatibility of silorane and methacrylate-based composites with pre-impregnated glass fiber by using flex...

The elapsed time prior to the placement of bonded restoration possibly affects the bond integrity of resin composite to bleached tooth. The purpose of this study was to evaluate the effect of elapsed time after tooth bleaching on microleakage of resin composite restorations with different adhesive systems. Seventy-two extracted sound human premolars were randomly divided into 6 groups of 12 tee...

abstract statement of problem: there is no enough published data about the shear bond strength of resin modified glass ionomer adhesives on caries-affected primary tooth dentin excavated using minimally invasive systems. objectives: to evaluate the shear bond strength of 2 different adhesives (one resin modified glass ionomer and one resin) using two caries removal techniques on healthy and car...

PURPOSE To assess the effects of three different dental adhesive systems on the formation of secondary root caries, in vitro, with a standardized interfacial gap in a filled cavity model. METHODS 40 sound human molars were selected and randomly assigned to four experimental groups: Clearfil SE Bond (CSEB), Xeno III (X-III), Scotchbond Multi-Purpose Plus (SBMP) and negative control (NC) withou...
