The aim of this study is to compare the effectiveness of Qscan plus™ (AIOBIO, Seoul, Korea) based on quantitative light-induced fluorescence (QLF) technology and disclosing agents in oral health programs in children.
A randomized crossover study was conducted for Korean children aged 6-11 years. Fifty-eight participants (29 to use Qscan plus™ first and 29 to use the disclosing agent first) were enrolled in this study. The participants were randomly divided into two groups. One group was assigned to brush with Qscan plus™, while the other group brushed with disclosed plaque visualization. One month later, the groups switched procedures. A total of 39 participants were analyzed, excluding those lost during the trial. There was no adverse event during the trial. The patient hygiene performance (PHP) index was used to assess oral hygiene status, and questionnaires about oral health behavior and attitude were completed. The data were analyzed using repeated-measure analysis of variance, with a significance level of < 0.05.
The PHP score decreased significantly on post-brushing and follow-up compared to baseline in both methods ( < 0.001), but there was no significant difference between the two methods. After oral hygiene education, participants' brushing time increased, and their oral care attitudes improved. More participants preferred the Qscan device to the disclosed plaque visualization because it is more easily noticeable.
The Qscan device has a similar educational effect as disclosing agents, and can be used as a supplementary tool to encourage children in oral hygiene education.
本研究旨在比较基于定量光诱导荧光（QLF）技术的Qscan plus™（韩国首尔AIOBIO公司）与示踪剂在儿童口腔健康项目中的有效性。
对6至11岁的韩国儿童进行了一项随机交叉研究。58名参与者（29名先使用Qscan plus™，29名先使用示踪剂）参与了本研究。参与者被随机分为两组。一组被分配使用Qscan plus™刷牙，而另一组使用示踪剂刷牙以可视化牙菌斑。一个月后，两组交换程序。共分析了39名参与者，排除了试验期间失访的参与者。试验期间未发生不良事件。使用患者卫生表现（PHP）指数评估口腔卫生状况，并完成了关于口腔健康行为和态度的问卷调查。数据采用重复测量方差分析进行分析，显著性水平<0.05。
两种方法在刷牙后和随访时的PHP评分均较基线显著降低（<0.001），但两种方法之间无显著差异。口腔卫生教育后，参与者的刷牙时间增加，口腔护理态度改善。更多参与者更喜欢Qscan设备而非示踪剂，因为它更容易被注意到。
Qscan设备与示踪剂具有相似的教育效果，可作为鼓励儿童进行口腔卫生教育的辅助工具。
