Effects of adhesion promoters on the shear bond strengths of orthodontic brackets to fluorosed enamel.
The aims of this in vitro study were to evaluate the effect of enamel fluorosis on the shear bond strength (SBS) of orthodontic brackets and to determine whether adhesion promoter, Enhance LC, increases the bond strength of brackets to fluorosed enamel. Forty-five (30 fluorosed and 15 non-fluorosed) non-carious fresh human premolar teeth, extracted for orthodontic reasons and without any caries...
متن کاملDeproteinization of Fluorosed Enamel with Sodium Hypochlorite Enhances the Shear Bond Strength of Orthodontic Brackets: An In vitro Study
CONTEXT Improving bonding strength to fluorosed teeh. AIMS To determine the effect of deproteinization using 5.25% sodium hypochlorite (NaOCl) prior to acid etching on shear bond strength of orthodontic brackets bonded to fluorosed teeth. SETTINGS AND DESIGN In vitro experimental study. METHODS AND MATERIAL Forty freshly extracted human mandibular first premolars with TFI 4 were selected ...
متن کاملShear bond strength of new and recycled brackets to enamel.
The purpose of this study was to evaluate in vitro the shear bond strength of recycled orthodontic brackets. S2C-03Z brackets (Dental Morelli, Brazil) were bonded to the buccal surfaces of 50 extracted human premolars using Concise Orthodontic chemically cured composite resin (3M, USA). The teeth were randomly assigned to 5 groups (n=10), as follows. In group I (control), the bonded brackets re...
متن کاملEffect of Quaternary Ammonium Salt on Shear Bond Strength of Orthodontic Brackets to Enamel
Objectives This study sought to assess the effect of quaternary ammonium salt (QAS) on shear bond strength of orthodontic brackets to enamel. Materials and Methods In this in vitro experimental study, 0, 10, 20 and 30% concentrations of QAS were added to Transbond XT primer. Brackets were bonded to 60 premolar teeth using the afore-mentioned adhesive mixtures, and the shear bond strength of t...
متن کاملShear Bond Strength of Orthodontic Brackets to Tooth Enamel After Treatment With Different Tooth Bleaching Methods
BACKGROUND Bleaching treatments decrease shear bond strength between orthodontic brackets and teeth; although definite results have not been reported in this regard. OBJECTIVES This study determined the effects of different bleaching protocols on the shear bond strength of orthodontic brackets to teeth. MATERIALS AND METHODS This experimental study was performed in Iran. Forty-eight extract...
