Vital Teeth Bleaching. Structural Analysis of the Enamel Surface Treated with Hi Lite.

Effects of bleaching on color stability of enamel lesions treated with resin infiltrant

Background and Aims: Considering the preventive and therapeutic effects of resin infiltration (RI) and the unknown effect of bleaching on the enamel treated with this method, this in-vitro study aimed to assess the effect of bleaching on color stability of enamel lesions treated with RI. Materials and Methods: In this in-vitro, experimental study, enamel-dentin samples measuring 5×5×3 mm were ...

Managing discoloured non-vital teeth: the inside/outside bleaching technique.

The discoloured, non-vital anterior tooth is a common aesthetic concern for many patients. It can have a profound effect on their self-esteem, interaction with others and employability. Discoloured non-vital teeth are frequently compromised owing to previous trauma, caries, endodontic therapy and failed restorations. Destructive invasive treatment options are likely to weaken the residual struc...

Effect of bleaching agents on enamel surface of bovine teeth: A SEM study

BACKGROUND This study aimed to evaluate changes in the enamel surface of bovine teeth after whitening with exogenous bleaching agents: 10% carbamide peroxide (group 1), 16% carbamide peroxide (group 2) and 35% hydrogen peroxide activated by a light-emitting diode (LED) (group 3). The evaluations were performed by scanning electron microscopy (SEM). MATERIAL AND METHODS Ninety bovine teeth wer...

In 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...
