AR tooth brushing system to promote oral care habits of children

It is needed to be careful about the places where bacteria can accumulate while brushing teeth [1]. But it is difficult to teach young children to brush their teeth properly. By the way, the system about hand-washing for children that superimposes bacteria illustrations on the route of contact infection has been proposed in our laboratory [2]. In this study, we propose new AR system to promote oral care habits of children. It detects tooth areas easily soiled in real time using machine learning technique first, and superimposes bacteria illustrations to show easily soiled areas. It is expected that children learn good tooth brushing habit.
