Title: SYSTEM AND METHOD FOR RANKING BACTERIAL ACTIVITY LEADING TO TOOTH AND GUM DISEASE
Abstract:
A system for the optical measurement of pH includes a light emitter to emit an excitation light, and a detector coupled to receive florescence light produced by a compound in a mouth of a patient in response to the excitation light. A controller is coupled to the detector, and the controller includes logic that when executed by the controller, causes the system to perform operations. The operations may include emitting the excitation light from the light emitter; measuring an intensity of the florescence light emitted from a surface of individual teeth in a plurality of teeth in the mouth; and determining, based on the intensity of the florescence light, one or more locations on the individual teeth likely to develop demineralization.
