The use of violet LED was recently introduced as a new alternative technique to perform tooth bleaching, associated or not with bleaching agents. This paper shows a tooth bleaching clinical case report performed in a 26-year-old woman, using a violet LED with 10% carbamide peroxide (CP). The tooth bleaching protocol was performed in 3 sessions. Fifteen irradiations using a violet light system (BMW, MMoptics, São Carlos, SP, Brazil) were done during 30 s (on) and 60 s (off) without bleaching gel, and more 5 irradiations associated to 10% CP. Upper and lower arches were irradiated separately. The total procedure time was 30 min. Subjective and objective color assessments were performed using Vitapan Classical shade guide and VITA Easyshade spectrophotometer, respectively. Dentin sensitivity was measured using a visual analogue scale. The use of violet LED associated to a low concentration carbamide peroxide successfully promoted tooth bleaching and no side effects i.e. dentin sensitivity during and post treatment was observed.
