Shear 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...
متن کاملEffect of Bleaching and Thermocycling on Resin-Enamel Bond Strength
The aim of this study was to evaluate the effect of bleaching and thermocycling on microshear bond strength of bonded resin composites to enamel. Enamel slices were prepared from ninety-six intact human premolars and resin composite cylinders were bonded by using Adper Single Bond 2 + Filtek Z350 or Filtek silorane adhesive and resin composite. Each essential group was randomly subdivided to tw...
متن کاملshear bond strength of orthodontic brackets to tooth enamel after treatment with different tooth bleaching methods
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...
متن کاملIn situ Effect of Nanohydroxyapatite Paste in Enamel Teeth Bleaching.
AIM Evaluate in situ the effect of nanohydroxyapatite paste (nano-HAP) before bleaching with hydrogen peroxide 35% (HP35%) by ion chromatography (IC) Knoop hardness number (KHN) and tristimulus colorimetry (TC). MATERIALS AND METHODS A total of 60 fragments were obtained from third molars included (3 mm × 3 mm × 3 mm) and the specimens were divided into three groups (n = 20): Gas chromatograp...
