Objectives
Narrative objectives1 There is a cylindrical toothbrush as an oral cleaning tool that has good cleaning efficiency and feels comfortable. A cylindrical toothbrush is a toothbrush with soft bristles planted at 360 degrees, and its cleaning efficiency has been proven in both artificial plaque and human intervention studies. In particular, as a feeling of use as compared with other products, there is a tendency that "easiness to remove plaque" is good and "pain during use" is small. In addition, there is a report that the refusal is alleviated by pursuing "comfort" for elderly people with dementia who refuse to take oral care. If both comfort and cleaning efficiency can be achieved by using a cylindrical toothbrush, it is considered to be very meaningful for oral care with people who cannot express their feelings like elderly people with dementia. However, "comfort" in a cylindrical toothbrush is limited to measurement by a subjective index and has not been evaluated objectively. Therefore, the purpose of this study is to evaluate the "comfort" when brushing with a cylindrical toothbrush by measuring electroencephalogram and electrocardiogram objectively.
