The purpose of this study was to investigate the effects of frequency, duration and systematicness of toothbrushing on the amount of dental plaque in school children. School children in four classes (n = 110, mean age = 13.5 years) were included. Data were collected using clinical examination and questionnaire. Data were first analyzed separately for girls and boys according to background factors and then by the components of toothbrushing, success in school, and the father's education. Boys had more plaque than girls did; the amount was influenced by background factors. Amount of plaque and frequency of toothbrushing were not clearly correlated with each other. Duration of brushing and amount of plaque, instead, were highly correlated. On the other hand, systematicness of brushing and amount of plaque were not clearly related. The results of this study indicated the need for broader evaluation of the information and methods used in oral health education in order to raise the effectiveness of habitual toothbrushing.
本研究的目的是调查刷牙的频率、时长和系统性对学童牙菌斑量的影响。纳入了四个班级的学童（n = 110，平均年龄 = 13.5岁）。通过临床检查和问卷调查收集数据。首先根据背景因素分别对女孩和男孩的数据进行分析，然后按刷牙的各个组成部分、学业成绩和父亲的教育程度进行分析。男孩的牙菌斑比女孩多；牙菌斑量受背景因素影响。牙菌斑量与刷牙频率之间没有明显的相关性。相反，刷牙时长与牙菌斑量高度相关。另一方面，刷牙的系统性与牙菌斑量没有明显关联。本研究结果表明，需要对口腔健康教育中使用的信息和方法进行更广泛的评估，以提高日常刷牙的效果。
