Abstract: A connected health care system is provided with various devices for tracking and monitoring health statistics and behaviors including oral health, fitness, heart health, bone health, salivary diagnostics, diabetes, and further options that will be explored in the subsequent sections. The connected health care system is comprised of various devices, a data transfer medium (i.e. “smartphone”), and the Cloud, which allows for data transfer between multiple platforms and devices. Some devices comprised in the connected health care system include a toothbrush, a connected surface with sensors, a salivary diagnostic system, a breath analysis system, and further devices that will be explored in the subsequent sections. The connected health care system further provides a user identification system utilizing capacitive coupling of the human body between devices.

Abstract: An oral health care implement and system are provided for use during oral health care activities. The oral health care implement has an oximetry sensor, most often in the embodiment of a transmissive or reflective pulse oximeter. The oximetry sensor provides blood oxygen saturation and heart rate measurements. The oral health care system has an oral health care implement, a first data transfer medium, and any combination of: a second data transfer medium, a network storage device, and a third data transfer medium. The system provides means for collecting a user's vital signs and transmitting data into a readable, usable form for the user via an oral health care implement.
