bonding brackets to the enamel surface has gained much popularity today. new adhesive systems have been introduced and marketed and a considerable increase in research regarding bond strength has been published. a considerable amount of these studies deal with shear bond strength of adhesives designed for orthodontic purpose. previous studies have used variety of test designs. this diversity in...

introduction: one of the clinical problems in orthodontics is the bonding of brackets tocomposite restorations. the aim of this study was to evaluate the shear bondstrength of brackets bonded to composite restorations using excite. methods:forty brackets were bonded to composite surfaces, which were embedded inacrylic resin. one of the following four protocols was employed for surfacepreparatio...

bond failure of brackets during orthodontic treatment is a common problem; which results in treatment interference, increased treatment time and prolonged clinical time for rebonding of failed brackets. the purpose of this study was to evaluate the effects of coca-cola and a non-alcoholic beer on the shear bond strength and adhesive remnant index (ari) of orthodontic metal brackets in vitro.eig...

Introduction: In orthodontic treatment, it is essential to establish a satisfactory bond between enamel and bracket. After the self-etch primers (SEPs) were introduced for the facilitation of bracket bonding in comparison to the conventional etch-and-bond system, multiple studies have been carried out on their shear bond strengths which have yielded different results. This study was aimed at co...

increased number of adult patients requesting orthodontic treatment result in bonding bracket to ceramic restorations more than before. the aim of this study was to evaluate and compare the shear bond strength of orthodontic brackets bonded to two types of ceramic bases with conventional orthodontic bonding resin and a new nano-filled composite resin.twenty four feldespathic porcelain and 24 li...

conclusions the bleaching procedures using 20% carbamide peroxide and 45% carbamide peroxide and diode laser significantly decreased shear bond strength of brackets to the teeth. 45% carbamide peroxide had a more significant effect on bond strength compared to 20% carbamide peroxide. the difference in bond strength was not significant between laser group and either carbamide peroxide groups. re...

statement of problem: bracket de-bonding during initial orthodontic archwire placement immediately after bracket set up or following re-bonding a single bracket can be a clinical concern. purpose: the aim of this in vitro study was to assess the effect of time on the shear bond strength of a no-mix orthodontic composite adhesive. materials and methods: seventy freshly extracted human upper firs...

BACKGROUND The purpose of this in-vitro study was to examine the effect of incorporating different concentrations of Zirconium oxide-Titanium dioxide (ZrO2-TiO2) nanoparticles, which can have antibacterial properties, on the mechanical properties of an orthodontic adhesive. METHODS ZrO2-TiO2 (Zirconium oxide, HWNANO, Hongwu International Group Ltd, China) -Titanium dioxide, Nanoshell, USA) na...
