background. acid etching prior to orthodontic bracket bonding may result in enamel wear or cracks following bracket removal. the manufacturer of fuji ortho lc glass-ionomer (gi) claims that it can bond brackets to wet unetched enamel. this study aimed to compare the bracket bond strength to etched and unetched enamel under dry and wet conditions. methods. in this in vitro study, 60 intact premo...

This paper summarizes a series of studies on the interface of fiber reinforced polymer laminates externally bonded to concrete substrates, carried out in the Laboratory of Engineering for Maintenance Systems, Hokkaido University. Appropriate test methods and bond models for shear bond, tensile bond and cleavage bond (bond under dowel force) are shown. Finally, experimental results on shear bond...

PURPOSE The purpose of this study was to evaluate and compare the effects of different surface pretreatment techniques on the surface roughness and shear bond strength of a new self-adhering flowable composite resin for use with lithium disilicate-reinforced CAD/CAM ceramic material. MATERIALS AND METHODS A total of one hundred thirty lithium disilicate CAD/CAM ceramic plates with dimensions ...

BACKGROUND CPP-ACP (Phosphopeptide-Amorphous Calcium Phosphate) has an important role in caries prevention in pediatric patients. This study was done, because of the great use of CPP-ACP and the need for restoration for teeth treated with CPP-ACP as well as the importance of shear bond strength of adhesives in the success of restorations. OBJECTIVES This study aimed to evaluate the effect of ...

statement of problem: shear bond strength (sbs) of home and office bleached enamel will be compromised by immediate application of composite restoration. antioxidant agent may overcome this problem. objectives: this in vitro study assessed the effect of green tea extract on shear bond strength of resin composite to in-office and home-bleached enamel. materials and methods: in this experimental ...

Introduction: Bond strength is an important property and determines the amount of force delivered and treatment duration in orthodontics. Many light-cured bonding materials are being used; but it is required to determine the most efficient one with desired bond strength. Objective: To determine and compare the shear bond strength of three visible light-cured composites (Transbond XT, Heliosit a...

statement of the problem: monomer viscosity and solvent evaporation can be affected by the adhesive system temperature. higher temperature can elevate the vapor pressure in solution and penetration of adhesive in smear layer. bonding mechanism may be influenced by the adhesive temperature. purpose: this study aimed to evaluate the effect of pre-heating on shear bond strength of etch-and-rinse a...

BACKGROUND An optimum bond strength at the resin-metal interface of a prosthesis is essential to the success of that prosthesis. Silicoater MD and Kevloc are two systems used to increase bond strength at the resin-metal interface. This study investigated the effect that surface pretreatment and chemical shelf life had on the bond strength of silicoated samples and compared the shear bond streng...
