A method for remotely assessing oral health of a user of a mobile device by obtaining, using the mobile device (40), at least one digital image (1) of said user's (30) oral cavity (31) and additional non-image data (2) comprising anamnestic information about the user (30). The digital image (1) is processed both using a statistical object detection algorithm (20) to extract at least one local visual feature (3) corresponding to a medical finding related to a sub-region of said user's oral cavity (31); and also using a statistical image recognition algorithm (21) to extract at least one global classification label (4) corresponding to a medical finding related to said user's oral cavity (31) as a whole. An assessment (10) of the oral health of said user (30) is determined based on the local visual feature(s) (3), the global classification label(s) (4) and the non-image data (2).

The apparatus according to the present disclosure comprises: a scanner that acquires a continuous 2D image within a measurement space; and a model generation unit for generating a three-dimensional virtual model by converting the image acquired from the scanner, wherein the model generation unit removes an area from the three-dimensional virtual model according to the reliability of data and generates a final model on the basis of the remaining area.

The present disclosure provides a measuring device for biological tissue by using an optical sensor, the device being compact enough to fit in a user's hand and casually usable by the user. The measuring device is provided with: an optical sensor that measures optical data about an object of measurement through a measurement surface in contact with the object of measurement by irradiating the object of measurement with light from a light emitter and causing a light receiver to receive reflected light that is reflected from the object of measurement, the object of measurement being a portion of biological tissue; a temperature sensor that measures the temperature of the optical sensor; and a data processor that processes the optical data on the basis of the temperature of the optical sensor and derives a measurement result pertaining to the object of measurement on the basis of the processed optical data.

A tongue-image-based diagnostic system and a tongue-image-based diagnostic method are disclosed. The diagnostic system includes a parameter collector configured to acquire environmental parameter information; a model establishment circuitry configured to perform a training process using image training data and the environmental parameter information and establish an estimation model; and an analysis circuitry configured to analyze acquired image information using the estimation model, and generate an analysis result corresponding to the acquired image information.

A computer program and computer-based system for remotely assessing oral health of a person by obtaining at least one digital image (1) of the person's oral cavity and additional non-image data (2) comprising anamnestic information about the person (30). The digital images (1) are segmented using statistical image segmentation algorithms (101,102) to extract visible segments (3), which are further processed to predict any invisible segments (6). The resulting segments are processed by a statistical object detection algorithm (104) using the non-image data (2) as further input to identify dental features (7), which are filtered to select only risk-related dental features (8) using a risk database (9) and mapped to respective tooth regions (11) or oral cavity regions (12) in an Oral Risk Atlas (10).

An optical analysis of saliva or a fluid-saliva mixture is performed in order to check whether the saliva or fluid-saliva mixture contains blood, which allows for determining whether or not a person may suffer from gingivitis or another condition affecting gum health. Light received from a representative volume of fluid (23) containing saliva is detected and analyzed. The analysis involves determination of at least one measurement value of light received by a light-receiving unit (25) for only a single wavelength of the light, particularly a wavelength that is associated with high absorption by a constituent of blood. It this respect, it is practical if the light-receiving unit (25) is configured to receive reflected light back from the volume of fluid (23). The optical analysis may be performed real-time during an action in a person's mouth involving a gum agitation effect, or after such action has taken place, for example.

A system is provided to treat sleep apnea, with a method of use. The system includes a handpiece which includes at least one penetrating electrode configured to penetrate tissue and one or more temperature sensors. A processor is coupled with the one or more temperature sensors and the at least one penetrating electrode, and a memory is configured to store instructions executable by the processor. The instructions, when executed, are operable to emit, by the at least one penetrating electrode, RF energy from the electrodes to heat a region of a base of a tongue until a target energy is delivered to the region. The instructions are also operable to measure, by the one or more temperature sensors, the temperature of the region.

An intraoral stimulation device configured to be positioned in a mouth of a patient. The device includes a sensor and one or more electrodes. The sensor is configured to monitor a position of the tongue and/or force exerted by the tongue against the sensor and to transmit a signal encoding tongue information. The electrode(s) is/are configured to deliver electrical stimuli to the patient's hard palate when the tongue information indicates that the tongue has moved from a desired position to an undesired position in the mouth. The electrical stimuli causes the tongue to move from the undesired position to the desired position.

For localizing gingival inflammation within a user's mouth the following steps are carried out using an oral care device (10): (i) sequentially emitting (520) light by a plurality of light sources (48) in a first sequential pattern, wherein at least some of the plurality of light sources are configured to emit light of different wavelengths; (ii) sequentially emitting (530) light in a second sequential pattern which is the reverse of the first sequential pattern; (iii) obtaining (540), by a light detector (40), reflectance measurements to generate first reflectance data from light emitted in the first sequential pattern, and to generate second reflectance data from light emitted in the second sequential pattern; (iv) averaging (550), by a controller (30), first reflectance data and second reflectance data for each wavelength to generate averaged reflectance data; and (v) determining (570), using the averaged reflectance data, whether gingiva at the location is inflamed.

A system comprises an image capture device, an augmented reality (AR) display to display, and a processing device. The processing deice receives image data of a dental arch from the image capture device and processes the image data using a plurality of detection rules, where each detection rule detects one or more dental conditions. The processing device determines a dental condition for the dental arch based on the processing, determines a position of an area of interest on the dental arch, wherein the area of interest is associated with the dental condition, generates a visual overlay comprising an indication of the dental condition at the position of the area of interest, and outputs the visual overlay to the AR display, wherein the visual overlay is superimposed over a view of the dental arch on the AR display at the position of the area of interest.
