External bleaching procedures utilizing highly concentrated 30-35% hydrogen peroxide solutions or hydrogen peroxide releasing agents can be used for tooth whitening. To enhance or accelerate the whitening process, heat-activation of the bleaching agent by light, heat or laser is described in the literature. The aim of the present review article was to summarize and discuss the available information concerning the efficacy, effects and side effects of activated bleaching procedures.
Information from all original scientific full papers or reviews listed in PubMed or ISI Web of Science (search term: (bleaching OR brightening OR whitening OR colour) AND (light OR laser OR heat OR activation)) were included in the review.
Existing literature reveals that activation of bleaching agents by heat, light or laser may have an adverse effect on pulpal tissue due to an increase of intra-pulpal temperature exceeding the critical value of 5.5 degrees C. Available studies do not allow for a final judgment whether tooth whitening can either be increased or accelerated by additional activation.
Therefore, application of activated bleaching procedures should be critically assessed considering the physical, physiological and patho-physiological implications.
利用高浓度30%-35%过氧化氢溶液或过氧化氢释放剂的外部漂白程序可用于牙齿美白。为增强或加速美白过程，文献中描述了通过光、热或激光对漂白剂进行热激活。本综述文章的目的是总结和讨论有关激活漂白程序的功效、作用和副作用的现有信息。
本综述纳入了PubMed或ISI科学网列出的所有原始科学全文或综述中的信息（检索词：（漂白或增亮或美白或变色）且（光或激光或热或激活））。
现有文献表明，由于牙髓腔内温度升高超过5.5摄氏度的临界值，通过热、光或激光激活漂白剂可能会对牙髓组织产生不利影响。现有研究无法最终判定额外激活是否能增加或加速牙齿美白。
因此，考虑到物理、生理和病理生理影响，应严格评估激活漂白程序的应用。
