Real-time measurement of total VSCs. Result obtained from two volunteers showing increasing EOT signal when air from their mouth is introduced to the RIfS sensor. (a) The graph presents real-time optical response recorded as the EOT signal taken from mouth air of two volunteers and air control. (b) The graph shows the comparison of VSC measures for three volunteers measured with our system, clearly representing the ability of our device to distinguish oral hygiene conditions based on oral VSCs.
