Combined Dental Bleaching Protocols and Time Required to Achieve Satisfactory Color

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. The primary outcome will be the number of days necessary to obtain satisfactory tooth color. Furthermore, tooth sensitivity and color changes measured with spectrophotometer will be assessed.
