Timeline
Interventions
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.
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.
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.
This group of patients did not undergo any whitening procedures.
