Objective: to evaluate clinically the use of desensitizing dentifrice, applied through a plastic custom tray, in pain reduction and colour variation caused by in-office dental bleaching. Material and Methods: for the study were selected 24 volunteers who were submitted to in-office dental bleaching in 3 clinical sessions with one week of interval, using bleaching gel (hydrogen peroxide - 35%). On the night of each bleaching session, volunteers used a plastic custom tray for 4 hours containing one of the dentifrices relative to the experimental groups: (1) Sucralose (S); (2) Sodium Phosphate (FS) and Calcium Silicate (SC) (NR-5 Technology). The pain was evaluated before the use of the plastic custom tray with dentifrice (S1, S3, S5) and after (S2, S4, S6) for 4 weeks using the analogue numerical scale with scores from 0 to 10. For colour variation (?E), a spectrophotometer (Easyshade) was used. Results: the FS and SC groups presented pain reduction in relation to the other groups (p
