A system for detecting blood in an oral cavity during brushing. The system may include a toothbrush having a sensor, the sensor is configured to emit first light of a first wavelength and second light of a second wavelength, receive a reflected portion of the first light and the second light, and generate a first signal indicative of a first intensity of the reflected portion of the first light and a second signal indicative of a second intensity of the reflected portion of the second light. The system may include a processor operably coupled to the sensor, the processor configured to receive the first signal and the second signal and calculate a ratio of the first intensity to the second intensity to determine whether hemoglobin / blood is present in the oral cavity. The processor may be part of the toothbrush or part of a portable electronic device such as a smartphone.
Description
Background technique [0001] Bleeding gums and other oral conditions can have a variety of causes. Some of these are mechanical problems, such as excessive brushing force, using a toothbrush with hard bristles, incorrect brushing or flossing, or improperly fitting dentures. Gum disease can also cause bleeding due to inflammation of the gum tissue. Other important causes may be systemic, such as medications (eg, blood thinners), pregnancy (hormonal changes), diabetes, vitamin deficiencies (eg, C or K deficiency), leukemia, and the like. Although the American Dental Association recommends that people with bleeding gums see a dentist or doctor, most people don't experience pain when they have bleeding gums and therefore ignore this advice. Accordingly, there is a need to provide consumers with toothbrushing systems that can monitor and / or record gum bleeding during routine brushing. Contents of the invention [0002] The present invention relates to a system and / or method for...
