OralCaddy (2016)

A prototype for a data streaming oral health caddy for behavioral health research.

Oral health is an important yet often neglected part of holistic health and wellness [1]. The mouth is a window into the health of the body [2]. Systemic diseases that affect the entire body may first show signs in the mouth in the form of lesions or other oral problems.

To advance behavioral health research in the oral health domain, I designed and prototyped a dental caddy that seamlessly integrates sensors to collect data on brushing and flossing. By doing so and with integration with targeted interventions, such a device might support oral health promotion and prevention of illnesses associated with poor oral health habits. This research was done at Northeastern University in collaboration with the Bouvé College of Health Sciences.

An LED is located near the base of each of the dental item compartments. They activate to indicate and remind the user to use a particular item such as the floss. A larger front flat panel LED in the base of the device can provide ambient awareness lighting.

This ambient light can be used to remind the user whether one has completed any oral health activity recently and indicate progress towards health behavioral goals. Force sensing resistors (FSR) are used in each holder of the caddy to detect removal and replacement of the items and activates data collection on the quantities of these activities. Data can be then sent wirelessly for analysis to inform health coaching.

3d printing was used to prototype initial designs. The final prototype as shown here was implemented using an off-the-shelf acrylic caddy modified to hold the toothbrush, toothpaste, and floss in an easily accessible way. All logic and sensing is driven by a Raspberry Pi 3 single-board computer which can be battery operated or plugged in. Logic and GPIO control is programmed using python. Data connectivity supporting wired or wireless protocols and general functionality can be further expanded to support future research and health intervention needs.
