The various embodiments described herein include methods, devices, and systems for customizing dental care. In one aspect, personalized toothbrush devices are 3-D printed for a plurality of users. A 3-D dental model of a respective user's mouth is obtained, and a configuration for a mouthpiece of a respective personalized toothbrush device is determined. The respective personalized toothbrush device is 3-D printed, and includes a top cleaning tray, a bottom cleaning tray, and a set of cleaning elements, each customized based at least in part on the 3-D dental model of the respective user's mouth. Each personalized toothbrush device is 3-D printed for each respective user of the plurality of users, and is different from every other user's personalized toothbrush device.

An electric toothbrush includes a gyro sensor inside a main body. The gyro sensor detects an angular velocity of the main body and the main body includes a head portion, a neck portion, and a grip portion in a longitudinal axis direction. An angle formed by a longitudinal axis of the main body in a state that brush bristles of the head portion contact with a brushing site in a dentition with respect to the longitudinal axis of the main body in a state that the brush bristles of the head portion contact with a reference position in the dentition is obtained, based on an output from the gyro sensor. A corresponding point corresponding to the brushing site on an approximate curve that curves corresponding to the dentition is obtained based on the angle, and coordinates of the corresponding point are used as a translational position of the brushing site.

The present application discloses an electric toothbrush, which relates to the technical field of toiletries, and specifically comprises a body and a toothbrush head, wherein two through holes are integrally formed at an end of an end cover at the front of the body, and two groups of lamp beads are installed on the inner side of the end cover near the top through the lamp control circuit board. The toothbrush head is composed of a sleeve, a central main rod and a vibrator docking unit as a whole, wherein the central main rod and the vibrator docking unit are all made of PMMA high light-transmitting plastic by integral injection molding. The present application improves the design on the basic structure of the existing split-type electric toothbrush, so that it can realize the disinfection and sterilization of each dead corner of the toothbrush head.

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.

A method for oral care. In one aspect, the method for oral care includes a) receiving sensor data from at least one sensor configured to detect motion of an oral care device during a brushing routine of a user, the sensor data corresponding to the detected motion; and b) determining a target brushing time based on the sensor data. In another aspect, the method for oral care includes a) receiving sensor data from at least one sensor configured to detect brushing intensity during a brushing routine of a user, the sensor data corresponding to the detected brushing intensity; and b) determining a target brushing time based on the sensor data.

There is provided a controller for a fluid-detection system, wherein the controller is configured to: determine if a user is interacting with the fluid detection system, wherein the determining comprises at least one of: determining whether a user is within a predetermined distance of the fluid detection system; determining whether a user is in physical contact with the fluid detection system; determining whether a fluid sensor of the fluid detection system is in a mouth of a user; and control the temperature of the fluid sensor of the fluid detection system based on the result of the determination. There is also provided a fluid based detection system comprising the controller, a device comprising the controller, a remote device comprising the controller, and a computer implemented method for controlling a fluid detection system, the method comprising the steps of: determining if a user is interacting with the fluid detection system, wherein the determining comprises at least one of: determining whether a user is within a predetermined distance of the system; determining whether a user is in physical contact with the fluid detection system; determining whether a fluid sensor of the fluid detection system is in a mouth of a user; and controlling the temperature of the fluid sensor of the fluid detection system based on the result of the determination.

An electric toothbrushing device is disclosed, the device comprising means (16) for producing vibration of a toothbrush head (14), means (24, 32, 40, 42, 44) for producing an orientation signal indicating of an area of the mouth being brushed, and means (47, 48, 49) for producing a pressure signal indicating a pressure applied to the toothbrush head. The device further comprises processing means (46) arranged to link values of the orientation signal with values of the pressure signal in order to provide feedback to a user regarding a brushing pressure applied to each of a plurality of different areas of the mouth. By linking values of the orientation signal with values of the pressure signal, the user can be better informed about which parts of the mouth are being or have been brushed too hard. This can help the user to correct their brushing technique.

An indexed drive system (10) for mechanised tools, in particular an electric toothbrush, for selectively imparting various drive modes to a pair of concentrically-arranged drive shafts (12, 14) thereby imparting various brushing modes to the head (H) of the mechanised tool, in particular an electric toothbrush.

The present invention relates to the field of battery powered electrical appliances or personal hygiene, in particular to a hair removal device such as an electric shaver or epilator as well as an electric toothbrush. A control device for a battery powered electrical appliance for personal hygiene is described, wherein the control device is adapted to cause the battery powered electrical appliance to perform automated contact fritting of a battery contact by controlling the battery powered electrical appliance such that a current pulse exceeding a wetting threshold is applied across the battery contact during a standby period.
