Investigation of a Modified Treatment Using Aquafresh® White Trays Revive

Objectives: To evaluate the consumers' perception of tooth brightening and the degree of tooth whitening as graded by the dental professional after 2 days of use of a hydrogen peroxide gel formulation in subjects who have previously bleached their teeth.Methods: This was a randomized, parallel group, examiner-blinded study to investigate the subjective “brightening“ response and the examiner Vita Shade assessment after using an 11.2% hydrogen peroxide (w/w) predosed gel in tray Aquafresh^® White Trays ^TM Revive^TM (AWTR) for 45 minutes once daily and subjects' own toothpaste or subjects' own paste only for respectively 1, 2 and 3 days. Only subjects with a Vita Shade score of A1 and greater and who had bleached their teeth within the last four years were included in the study. AWTR was used for 3 days. All subjects brushed twice daily for one minute using their own toothpaste and toothbrush. Compliance, oral soft tissue tolerance and toothsensitivity were daily monitored during the study. Results: When used over a three day period, AWTR produced statistically significant consumer noticeable brightness and examiner quantifiable whitening in subjects who had previously bleached their teeth after 1, 2 and 3 days use, respectively, compared to the brushing-only group. The number and type of oral findings were similar to what has been reported with the use of marketed whitening products.Conclusion: A predosed gel in tray can be used for two days to whiten teeth in people who have previously used OTC and professional whitening treatments.
