Abstract
A system () for detecting tissue inflammation, and gingivitis specifically, including a light emitter () configured to emit light at a tissue region () within a user's mouth; a light detector () configured to detect optical signals diffusely reflected through the tissue region over a period of time; a controller () configured to: determine a slope signal (Q) based on at least two signals (R(λ), R(λ)) from the optical signals, the at least two signals including at least one signal from a hemoglobin-dominated wavelength range; determine one or more characteristics of the slope signal; and select a best measurement signal based on the one or more characteristics of the slope signal. The system further includes a user interface () configured to provide information regarding a position of a probe for accurate detection of tissue inflammation based on the one or more characteristics of the slope signal.
