Summary

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.

Detailed description

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.

Conditions

• Tooth Discoloration

Interventions

Type	Name	Description
PROCEDURE	In-office bleaching system	As the whitening agent, an in-office bleaching system containing 35% hydrogen peroxide (Whiteness HP, FGM) was chosen. The gingiva was isolated using an isolation material (Opaldam, Ultradent Products Inc.), which was light-cured with a standard curing light. The whitening gel was applied to the labial surfaces of the maxillary incisors and canines with a 1mm thickness and left for 20 minutes. After cleaning the teeth with an aspiration tip, the whitening procedure was repeated.
PROCEDURE	Laser-assisted bleaching	Whitening was performed 10 days prior to treatment, with laser treatment applied without removing brackets in the fixed appliance group and without cleaning attachments in the aligner group. The laser was applied to the buccal surface of the teeth with a 1mm distance for 30 seconds in three applications. After a 10-minute rest, the laser procedure was repeated.
PROCEDURE	Home-bleaching	The whitening trays were custom-made for the fixed appliance patients, and they used them for 2-4 hours each evening after brushing their teeth. In the transparent aligner group, whitening was done using the aligners worn for treatment.
OTHER	Control	This group of patients did not undergo any whitening procedures.
