To investigate the impact of "Brush Up" - a mobile application, on oral hygiene behaviours of 4-6-year-old children in Bangalore city.
In this experimental study, 247 children aged 4-6, were randomly divided into three groups. Considering "Brush Up" is a mobile application, parents of the children in Group 1 (n=82) downloaded the application on their smartphones. Children in Group 2 (n=83) and Group 3 (n=82) received tooth brushing instructions by an educative video and manual demonstration, respectively. Effectiveness of tooth brushing was assessed with plaque scores, which were recorded for all the groups at baseline and one month using Visible Biofilm Index.
Wilcoxon signed rank test showed a significant improvement in the tooth brushing behaviour for the Brush Up group, which was indicated by a lower plaque score after a follow-up of one month. Kruskal-Wallis test followed by post-hoc test showed that the mean ranks of plaque scores of Brush Up group are consistently lower than those of video demonstration group and manual demonstration group.
The lower plaque score in subsequent follow-up in Brush Up group suggests that using a smart system can enhance learning a correct tooth brushing method in young children and can also help in implementing the required reinforcement and motivation to brush and aid in better plaque control.
探究“Brush Up”(一种移动应用程序)对班加罗尔市 4-6 岁儿童口腔卫生行为的影响。
在这项实验研究中,随机将 247 名 4-6 岁儿童分为三组。考虑到“Brush Up”是一个移动应用程序,第 1 组(n=82)的儿童家长在其智能手机上下载了该应用程序。第 2 组(n=83)和第 3 组(n=82)的儿童分别通过教育视频和手册演示接受刷牙指导。使用可视菌斑指数在基线和一个月时记录所有组的菌斑评分,以评估刷牙效果。
Wilcoxon 符号秩检验显示,Brush Up 组的刷牙行为有显著改善,一个月后的随访中菌斑评分较低。Kruskal-Wallis 检验后进行的事后检验显示,Brush Up 组的菌斑评分均值始终低于视频演示组和手册演示组。
Brush Up 组在后续随访中较低的菌斑评分表明,使用智能系统可以帮助幼儿学习正确的刷牙方法,并提供所需的强化和激励,以帮助更好地控制菌斑。
