Abstract
Whitening of fluorosis stains ranging from yellow to dark brown presents a great challenge to the dentists. The aim of this study was to report the clinical case of a 32-year-old female patient with moderate fluorosis, who was treated using the combination of light-assisted in-office and at-home whitening system. The in-office whitening was performed using 25% hydrogen peroxide (Zoom DayWhite, Discus Dental, Stamford, USA) for four 15-min sessions with supplemental light (Philips Zoom, Stamford, USA) immediately followed by home whitening with a take-home custom tray using 22% carbamide peroxide (Zoom NiteWhite, Discus Dental, Stamford, USA) worn for 6 h a day for 1 week. Color measurements using a dental spectrophotometer (Spectroshade, MHT Optic Research AG, Niederhasli, Switzerland) after the first week showed that the suggested combination technique provided a fast whitening result with a high degree of patient satisfaction. The in-office whitening with light exhibited to be an efficient method for removing yellow and brown fluorosis stains, while the at-home whitening was useful for obtaining a uniform tooth shade. At the 6-month and 1-year recall, the teeth shade and appearance were evaluated. The results of this case report clearly show an effective esthetic result in the long term; however, the question of whether appropriate color stability would be provided by the technique still remains to be answered.
