- Registration Number
- NCT03514797
- Lead Sponsor
- André Luis Faria e Silva
- Brief Summary
This parallel, randomized, and controlled clinical trial will assess the effect of a single prior session of in-office dental bleaching on time required to achieve satisfactory tooth color with at-home bleaching. Participants enrolled will randomly allocated to receive or not a single session of dental bleaching with 35% hydrogen peroxide applied for 45 min. Following, all participants will use customized trays filled with 10% carbamide peroxide for 1h per day until obtain satisfactory results.
