Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
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.

Study Groups
Review each arm or cohort in the study, along with the interventions and objectives associated with them.
Conventional
In this group, 14 patients (7 with fixed appliances and 7 with clear aligners) underwent conventional whitening procedures during the treatment process. As the whitening agent, an in-office bleaching system containing 35% hydrogen peroxide (Whiteness HP, FGM) was chosen.
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.
Laser-assisted bleaching
In this group, 14 patients (7 with fixed appliances and 7 with clear aligners) underwent laser whitening with a 940 nm diode laser and a 35% hydrogen peroxide gel (Whiteness HP, FGM).
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.
Home bleaching
In the home whitening group, 14 patients (7 with fixed appliances and 7 with clear aligners) underwent a 14-day home whitening treatment during the treatment process using a 16% carbamide peroxide gel (Opalescence PF, Ultradent Products Inc., South Jordan, UT, USA).
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.
Control
The 14 patients randomly selected (7 with fixed appliances and 7 with clear aligners) served as the control group. No whitening procedures were performed on the patients in this group.
Control
This group of patients did not undergo any whitening procedures.
