Plaque control is very important in the treatment of periodontitis. However, plaque is difficult to remove because one cannot see one's own oral cavity. The purpose of this study was to verify the plaque removal effect of a prototype device that has a built-in image sensor in the head of an electric toothbrush, enabling the user to brush while checking the condition of the tooth surface on a monitor in real time and to assess their sense of use.
The subjects were 10 fifth-year students from the Graduate School of Dental Science, Fukuoka Dental College, Fukuoka, Japan. The subjects were divided into those who used electric toothbrushes while having the condition of the tooth surface checked with a monitor (monitor group) and those without a monitor (non-monitor group). O'Leary plaque control records before and after brushing and the brushing time were measured, and questionnaires were given to the subjects after brushing. Scaling and professional tooth cleaning were performed after completing the questionnaire. One week later, subjects were switched to the opposite group and had the same measurements and questionnaires. The Wilcoxon signed-rank test was used to compare both groups before and after the examination at a 5% significance level.
The monitor group had significantly better plaque removal than the non-monitor group. In addition, the monitor group spent significantly more time brushing than the control group.
Brushing while monitoring oral conditions in real time using an electric toothbrush with a built-in image sensor showed that significantly better plaque removal can be achieved with a longer brushing time.
菌斑控制在牙周炎治疗中非常重要。然而，由于人们无法看到自己的口腔，菌斑很难清除。本研究的目的是验证一种原型设备的菌斑清除效果，该设备在电动牙刷头部内置图像传感器，使用户能够在实时查看监视器上牙齿表面状况的同时刷牙，并评估他们的使用感受。
受试者为日本福冈齿科大学齿学部研究生院的10名五年级学生。受试者被分为两组，一组在使用电动牙刷时通过监视器检查牙齿表面状况（监视器组），另一组不使用监视器（非监视器组）。测量刷牙前后的奥利里菌斑控制记录和刷牙时间，并在刷牙后向受试者发放问卷。完成问卷后进行龈上洁治和专业牙齿清洁。一周后，受试者切换到另一组，进行相同的测量和问卷调查。采用Wilcoxon符号秩检验，以5%的显著性水平比较两组检查前后的情况。
监视器组的菌斑清除效果明显优于非监视器组。此外，监视器组的刷牙时间明显长于对照组。
使用内置图像传感器的电动牙刷实时监测口腔状况时刷牙表明，刷牙时间越长，菌斑清除效果越好。
