A brush with an LED light source includes a body, and a head provided at a tip of the body, the head including a housing part connected to the body, a support part detachably attached to the housing part, a brush part formed of a plurality of bristles planted in the support part, and a light-source part provided inside the housing part, wherein the light-source part has a first LED for emitting light having a peak in a first wavelength band and a second LED for emitting light having a peak in a second wavelength band different from the first wavelength band.

A powered scrubbing wand assembly for scrubbing a surface includes a handle that can be gripped during cleaning activities. A cleaning head is coupled to the handle and a drive unit is integrated into the handle. The drive unit rotates in a first direction when the drive unit is turned on. A spray unit is integrated into the handle for spraying a fluid soap when the spray unit is turned on. A plurality of scrubbers is each removably attachable to the cleaning head. The drive unit rotates the scrubber on the cleaning head when the drive unit is turned on thereby facilitating the scrubber to scrub a surface.

A dental cleaning appliance includes a fluid reservoir for storing working fluid, a nozzle for delivering working fluid to the teeth of a user, a light source for illuminating the fluid reservoir and a control circuit for activating the light source to generate an alert which is conveyed to the user through the illumination of the fluid reservoir.

Oral hygiene monitoring system is disclosed to track motion and orientation of an oral hygiene device. The control system may process data output from a motion sensor to determine position and orientation of an oral hygiene device with respect to a user's mouth. In some examples, the system may use machine learning techniques to identify position and orientation, brush stroke type, and other specific actions.

The invention relates to a hand-held device for excitation and irradiation of pathogenic microorganisms in the mouth and throat, e.g. a toothbrush comprising at least one excitation light source in the short-wave visible spectral range for auto-fluorescence excitation of the pathogenic microorganisms, at least one primary irradiation light source in the red spectral range for primary irradiation of the pathogenic microorganisms and for transillumination, and optionally at least one secondary irradiation light source in the visible spectral range for secondary irradiation of the pathogenic microorganisms, wherein the irradiation light sources have spectral components that can be absorbed by endogenous porphyrins, which are produced by the pathogenic microorganisms, whereby a fluorescence excitation and an inactivation of the pathogenic microorganisms occurs on the basis of subsequent processes. In order to prevent the unintentional irradiation of the eyes, a pressure sensor is designed to release higher light intensities only once a contact pressure has been measured. In addition, the radiation must leave the hand-held device in a divergent manner. The spatially resolved detection of the fluorescence of the pathogenic microorganisms can optionally be used to induce the inactivation of the bacteria by targeted irradiation in the fluorescent range.

A device for treating hair or scalp, the device comprises a dispenser connected to a cartridge, wherein the cartridge comprises a formulation; a plurality of tips, wherein the tips have at least one opening to dispense the formulation; and a controller that controls the amount of formulation that is dispensed from the tips.

A hair and scalp treatment device includes a dispenser connected to a cartridge, wherein the cartridge comprises a formulation; a plurality of tips on the device, wherein the tips have at least one opening to dispense the formulation and at least one LED that emits light in the visible color spectrum, wherein the at least one LED is located at the end of the tips; and a controller configured to individually turn on and off the LEDs from the plurality of tips.

An optical analysis of saliva or a fluid-saliva mix obtained during or after an oral care action is performed in order to check whether the saliva or fluid-saliva mix contains blood, which allows for determining whether or not a person may suffer from gingivitis or another condition affecting gum health. In particular, light received from a representative sample (23) containing saliva is detected and analyzed. The analysis involves determination of measurement values of light received by a light-receiving unit (25) for one or more main wavelengths of the light and one or more auxiliary wavelengths of the light. Advantageously, the main wavelength(s) is/are associated with high hemoglobin absorption and the auxiliary wavelength(s) is/are associated with low hemoglobin absorption. A measurement value at an auxiliary wavelength is used for correcting a measurement value at as main wavelength for background influences.

A toothbrush can include a handle and a head. At least one bristle can be attached to the head. The toothbrush can also have an illumination member, an illumination circuit and an activation device. A pliant base on the handle can be used to activate the activation device to initiate the illumination circuit.

The present invention relates to an apparatus comprising an insertion member configured to be inserted to a user's mouth. The insertion member comprises one or more illumination sources, configured to illuminate a part of the user's mouth when inserted thereinto; one or more imaging devices configured to capture images of the user's mouth interior; and a processing module configured to receive images from the one or more imaging devices, process the images to data, and detect oral and/or dental anomalies from the processed images and send the processed images and data via wireless or wired connection to a physician or professional doctor for further analysis.
