Esthetic dentistry has received increased attention in recent years, as people are more aware of the esthetic appearance of their teeth, including alignment and whiteness. This development, combined with a decrease in the incidence and severity of caries, has directed some clinicians toward conservative and non-invasive treatments such as tooth bleaching. A number of methods for nonvital tooth bleaching are described in the literature; these procedures rely on the bleaching agent used, the agent's concentration, product format, and the source of light activation. This article presents two case reports in which dental bleaching with halogen light-activated agents was used to treat a nonvital discolored incisor. The advantages and disadvantages of the technique are discussed.
近年来，随着人们越来越关注牙齿的美观外观，包括排列和洁白度，美容牙科受到了更多关注。这一发展趋势，再加上龋齿发病率和严重程度的降低，促使一些临床医生倾向于采用保守和非侵入性的治疗方法，如牙齿漂白。文献中描述了多种用于死髓牙漂白的方法；这些方法取决于所使用的漂白剂、漂白剂的浓度、产品形式以及光激活源。本文介绍了两例使用卤素光激活剂进行牙齿漂白治疗死髓变色切牙的病例报告。并讨论了该技术的优缺点。
