Followed the increasing of living standard, consumers expect to have a batter quality of lives. Nowadays, consumers require a product having not only functional satisfaction, but also emotional attraction. Products have to play a role of pleasing users when using them. It is therefore that designing a toothbrush is required not only a well-designed ergonomic, but also a toothbrush handle with comfort and grips. Finally, the toothbrush has to be able to clean up teeth bacteria effectively. The most important thing is to provide a pleasurable experience during brushing teeth processes. In order to developing the toothbrush, there are three aims: (1) the study of how musical rhythm and melody affect the movement of brushing teeth. (2) the study of how musical rhythm and melody affect users’ emotional responses. (3) the comparative study on cleaning plaque between traditional toothbrush and music toothbrush. Dental hygiene is depended on the using toothbrush daily, while proper oral hygiene and care are essential.

This study attempts to explore the connections between the movement of brushing-tooth and music rhythms and melodies. At the end, the finding of results can be used and integrated into a music toothbrush design. This is an empirical research study. This research will be started with the sound analysis of brushing tooth. According to the result of prior analysis, we will collect as much rhythms and melodies as possible, which related to the result of prior analysis. Experimental 1 will be conducted to find the most suitable background rhythm for brushing tooth. Experimental 2 will also be conducted to find the most suitable background melody for brushing tooth.
