A toothbrush apparatus, a method, and a medical system. The apparatus includes a sensing module configured to detect one or more brushing parameters for determining at least a brushing intensity. One or more processors are communicatively coupled to the sensing module and are configured to determine at least the brushing intensity and output the determined brushing intensity.

A filament for an oral care implement has a longitudinal axis and a substantially cross-shaped cross-sectional area extending in a plane substantially perpendicular to the longitudinal axis. The cross-shaped cross-sectional area has four projections and four channels. The projections and channels are arranged in an alternating manner. Each channel has a concave curvature formed by neighboring and converging projections. The concave curvature has a radius, and each projection is end-rounded thereby forming a curvature. The curvature has a diameter, and the ratio of the diameter of the curvature of the projection to the radius of the curvature of the channel is from about 0.2 to about 1.5.

Skin brush heads configured for use with a motorized personal appliance include a body having an inner surface and an outer surface, and a treatment applicator coupled to the outer surface of the body. The treatment applicator includes a plurality of cleansing agent-infused bristles extending away from the outer surface of the body, the plurality of cleansing agent-infused bristles being configured to remove particles from a skin portion by adsorption.

A smart toothbrush control circuit, a smart toothbrush, and a smart tooth-brushing behavior monitoring method are provided. The smart toothbrush control circuit includes: a main control module, a brush head module, a position detection module, and a pressure detection module. The main control module is connected to a cloud server by a smart terminal. The main control module uploads oral data to the cloud server so as to implement deep-level data analysis and processing on the oral data. The main control module generates a control signal according to the oral data, and the brush head module, the position detection module and the pressure detection module send a variety of behavior guidance and prompts to a user on the basis of the control signal. The smart terminal synchronously display a tooth-brushing behavior of the user on the basis of the control signal.

A wear-out assessment for an oral care system (14) (e.g. an oral cleaning device) is disclosed. A sensor unit (16) of the oral care system is adapted to provide a sensor signal related to a cleaning efficacy of a cleaning function of the oral care system. The sensor unit (16) may be, or may be coupled to, a component which is used during execution of an oral care function of the device, for example a sensor for detecting cleaning progress in the mouth, or a component which drives a cleaning or treatment action in the mouth. The sensor signal (20) is used for performing a wear-out assessment via monitoring characteristics of a signal which is indicative of progress of the oral cleaning efficacy during an operation session (e.g. a clean level in the mouth) and monitoring a length of time that it takes for a certain threshold of efficacy to be reached in a session. If the length of time is over a certain threshold, this can be an indication that the relevant components of the oral care system are wearing out.

Disclosed are an artificial-intelligence-based toothbrushing recommendation method, apparatus and device, and a storage medium. The toothbrushing recommendation method includes: acquiring toothbrushing data and brush head data detected by a data detection apparatus in an intelligent toothbrush; analyzing the toothbrushing data, and compiling statistics to obtain a toothbrushing condition of each toothbrushing surface, wherein the toothbrushing condition includes a toothbrushing duration, a toothbrushing strength, a toothbrushing amplitude and a horizontal brushing condition; analyzing the brush head data to obtain a brush head condition of the intelligent toothbrush; and forming a recommended first toothbrushing scheme according to the toothbrushing duration, the toothbrushing strength, the toothbrushing amplitude, the horizontal brushing condition and the brush head condition.

A dental health and care system utilizes an image capturing module installed on a teeth cleaning device in order to capturing teeth images during the cleaning of teeth of a user. Teeth images can be submitted to a care service center to determine whether the oral care is proper performing, the teeth is cleaning, and any symptom is in the teeth thereof. In addition, it is able to further provide diagnosis recommendations containing medical treatment information in order to timely report to the care giver of the child, elderly or care receiver or to the user for improvement on the health habit or as outpatient reference. Professional consultation and recommendation can also be provided in order to achieve the effect of providing assistance to the user or the entire family members in their understanding of the dental health and care condition through daily teeth cleaning actions with ease.

A folding self-cleaning toothbrush is configured with of a head having bristles, a handle with an open recess wherein the head can be stored, a joint which allows the head to fold into the handle, a battery, and a sanitization device with LED lights that emit light in a spectrum suitable for cleaning the head/bristles. The head may be detachable and disposable. The toothbrush also has a computing system for controlling activation of the UV light emitter/sanitization device, as well as to generate notifications related to use and/or cleaning of the toothbrush.

Tooth brushing monitoring system is disclosed that includes a toothbrush with sensors and a base station. The sensors record data regarding the quality, quantity and location of brushing and the system can analyze the data to provide feedback on the quality of brushing. This feedback provides motivation for users to increase their brushing habits, leading to a decrease in plaque, tooth decay and gingivitis.

There is provided an electric toothbrush including a toothbrush head, a toothbrush handle and a force sensing array. The force sensing array is arranged on the toothbrush head and/or the toothbrush handle. When the force sensing array is arranged on the toothbrush head, it is able to detect the force uniformity of brush hairs. When the force sensing array is arranged on the toothbrush handle, it is able to control the vibration strength of the brush hairs and detect the pressing force of the brush hairs.
