A dental sensor system has a dental appliance that is adapted, to be positioned within a mouth of a user. The dental appliance has at least one cavity within the dental appliance, a power generation system operably mounted on the dental appliance for generating power from movement of the user's mouth, and a battery mounted in the at least one cavity and operably connected to the power generation system. A sensor system is mounted in the at least one cavity and operably connected to the battery, and includes at least one sensor for sensing the data related to the user.

An oral irrigator system having an ergonomic casing with a pliable nozzle assembly, and coupled to a detachable and refillable fluid reservoir. The ergonomic casing contains a power source and a pump mechanism. The detachable nozzle head delivers a pulsating jet of fluid with adjustable speed into the oropharyngeal cavity. When the system is turned on, the rechargeable battery activates the diaphragm pump to draw fluid from the reservoir using a fluid pipe and delivers the fluid to the tip of the nozzle head.

Devices for whitening teeth that include a mouth piece and an ultraviolet light source, a sterilizer that sterilizes the mouth piece, or at least one Hall-effect sensor. At least a portion of the device or mouth piece may be sterilized. A wireless charging system may drive the sterilizer or UV source, which may operate only when the mouth piece is not in the user's mouth or when the mouth piece is charging. A safety mechanism may protect the user from eye damage. The mouth piece may be charged while the mouth piece and UV source are in an enclosure. The UV source or sterilizer may turn on only while the mouth piece is in the enclosure or only while the enclosure is closed. The Hall-effect sensor(s) may control whether the UV source or sterilizer is on or may detect whether the mouth piece is docked within the charger.

An electric toothbrush includes a handle, a toothbrush head, and a charging base. One end of the handle is configured for outputting ultrasonic vibrations. The toothbrush head is configured for simultaneously wrapping upper and lower rows of teeth of a human body. The toothbrush head is configured to be disposed on the end of the handle and vibrates with the end of the handle to simultaneously clean the upper and lower rows of teeth of the human body. The charging base is disposed at the other end of the handle and charges the handle. And the charging base includes a sterilization unit for sterilizing the handle and the toothbrush head. The electric toothbrush provided by the present application is convenient to operate, and is configured for being charged through a charging base and being sterilized after being used, with complete functions and a wide application range.

A light device includes an elongated arm comprising a plurality of light emitting diodes (“LEDs”) disposed at a first end of the elongated arm and configured to be positioned inside an oral cavity and to deliver one of a plurality of types of light treatments to the inside of the oral cavity according to a selected one of a plurality of operating modes. The light device further includes a body coupled to the elongated arm at a second end of the elongated arm. The body includes a battery for providing power to the LEDs. The body further includes a mode module coupled to the battery and the plurality of LEDs and configured to deliver power from the battery to at least one of the plurality of LEDS based on the selected operating mode.

A light curing dental system comprising a light emitting tray that precisely distributes an optimal amount of curing light energy to internal, external and extra oral portions of the dental arch to cure a dental material. The light curing dental system generally includes a light source, a light emitting dental tray, an activation module and a photocurable dental material.

The system according to the invention comprises: a handpiece, to which an endodontic instrument can be connected that is intended to be inserted into a root canal, a measurement unit for measuring a magnitude related to the position of the endodontic instrument in the root canal and a computation and display unit for displaying a graph representing the evolution of the magnitude measured by the measurement unit during an endodontic treatment with the endodontic instrument. The method according to the invention comprises the following steps: displaying, by means of a computation and display unit, a graph representing the evolution of a magnitude measured during a root canal treatment performed by the dentist, the magnitude being related to the position of an endodontic instrument in the root canal, and providing a reference graph representing a predetermined endodontic treatment technique to allow a comparison to be made between the graph representing the evolution of the measured magnitude and the reference graph.

Disclosed is a teeth cleaning apparatus, including a first liquid reservoir, a teeth cleaner, a connector, and a liquid conveyer. The teeth cleaner includes a teeth cleaner body and a second liquid reservoir that is fixedly connected to the teeth cleaner body and transmits a teeth cleaning liquid to the teeth cleaner body during teeth cleaning. The connector is separable from the teeth cleaner, and the liquid conveyer transmits the teeth cleaning liquid in the first liquid reservoir to the second liquid reservoir when the teeth cleaner is connected on the connector.

The present invention relates to the field of a small electrical appliance, in particular hair removal device or toothbrush, comprising an electric DC motor; a detector for acquiring a detector signal indicative of a rotational speed of the electric DC motor; and a controller for controlling the electric DC motor. The controller is adapted to: determine, based on the detector signal, a first parameter indicative of the rotational speed of the DC motor; determine, based on the detector signal, a second parameter indicative of the rotational speed of the DC motor, wherein the second parameter is different from the first parameter, and wherein the second parameter is determined based on a frequency domain analysis of the detector signal; and adjust a supply voltage of the electric DC motor based on the first parameter and the second parameter.
