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.
最近，人们引入了一种使用紫色发光二极管（violet LED）的新技术，作为一种新的牙齿漂白替代方法，该技术可与漂白剂联合使用或不联合使用。本文展示了一个使用 10%过氧化脲（carbamide peroxide，CP）的紫色发光二极管（violet LED）对 26 岁女性进行牙齿漂白的临床病例报告。牙齿漂白方案分为 3 个阶段进行。在没有漂白凝胶的情况下，使用紫色光系统（BMW，MMoptics，São Carlos，SP，巴西）进行了 15 次 30 秒（开）和 60 秒（关）的照射，另外还进行了 5 次与 10% CP 联合的照射。上、下颌弓分别进行了照射。整个过程耗时 30 分钟。使用 Vita Classical 比色板和 Vita Easyshade 分光光度计分别进行了主观和客观的颜色评估。使用视觉模拟量表测量牙本质敏感性。使用紫色发光二极管联合低浓度过氧化脲成功地促进了牙齿漂白，并且在治疗期间和治疗后没有观察到任何副作用，如牙本质敏感。
