Bleaching Procedures Performed During Treatment With Brackets and Clear Aligners

Comparison of Different Teeth Bleaching Methods Performed During Fixed and Clear Aligner Orthodontic Treatments: A Randomized Controlled Clinical Trial

The aim of this study is to compare the effectiveness of different whitening methods used during orthodontic treatment with fixed appliances and clear aligners. It also aims to examine the effect of different whitening methods on white spot lesions and the color change they cause in the teeth.

During orthodontic treatment, if oral hygiene is not properly maintained or in long-term treatments, tooth discoloration may occur. In clear aligner treatment, failure to regularly clean the aligners or the consumption of staining foods and beverages while wearing the aligners can lead to staining and yellowing of the tooth surfaces.

The aim of this study is to compare the effectiveness of different whitening methods used during orthodontic treatment with fixed appliances and clear aligners. It also aims to examine the effect of different whitening methods on white spot lesions using quantitative light-induced fluorescence (QLF) and to evaluate the color changes in the teeth during the treatment process.
