BACKGROUND
The aim of this study was to evaluate efficacy of violet LED light for the bleaching treatment of primary incisors darkened by trauma.
METHODS
Twenty deciduous incisors with color change were selected, divided into two groups: control - no bleaching protocol was applied, and VL- treated with violet LED. The change color analysis was taken in each tooth, by spectrophotometer. In three different time: baseline - before treatment, after 4 treatment sessions and after 8 treatment sessions.
RESULTS
The color change data were analyzed using ANOVA and a post- hoc Tukey tests (α=0.05). After 4 and 8 sessions no differences were observed between the groups (p<0.05).
CONCLUSIONS
Thus, it can be concluded that violet LED light was not effective in bleaching primary incisors darkened by trauma after 8 sessions.
背景
本研究的目的是评估紫光发光二极管（LED）灯对因外伤而变色的乳切牙进行漂白治疗的效果。
方法
选取20颗变色的乳切牙，分为两组：对照组——不进行漂白方案处理；紫光LED治疗组——用紫光LED进行治疗。使用分光光度计对每颗牙齿进行变色分析。在三个不同时间点：基线——治疗前、4次治疗后和8次治疗后。
结果
使用方差分析和事后Tukey检验（α = 0.05）对变色数据进行分析。4次和8次治疗后，两组之间未观察到差异（p < 0.05）。
结论
因此，可以得出结论，紫光LED灯在8次治疗后对因外伤而变色的乳切牙进行漂白无效。
