The invention relates to a dental tool having a shank region, which is formed for coupling to a dental handpiece, and also having a work region, which is connected to the shank region. In this case, the shank region of the dental tool is formed so that there is the possibility of latchable insertion and removal without actuation. In particular, at least the shank region can consist of plastics material. As a result, inter alia facilitated handling of the tool and inexpensive production of the tool are rendered possible.

An oral device for checking a time to go to a dentist. The oral device includes a pH sensor configured to measure pH within an oral cavity, a housing on which the pH sensor is mounted, a processor configured to analyze measured pH from the pH sensor, and a wireless communication unit functionally connected to the processor and configured to perform communication with an external device. The oral device is useful for a patient who needs continuous management such as an implant surgery patient by allowing the patient to visually and easily check a time to go to a dentist and an individual oral condition of the patient. Further, by allowing the user to simply check the condition of the oral cavity at home, it is possible to more effectively manage the condition of the teeth and to save medical expenses.

Disclosed herein is an electric toothbrush with a toothpaste cartridge. The electric toothbrush may include a main body with a top end adapted to engage with a removable brush attachment. The main body may be configured to accommodate the toothpaste cartridge, one or more conduits, a servo mechanism, a controller, and an energy storage device. The removable brush attachment having an elongated structure configured to be removably attached to the main body. The elongated structure may include a first end including a brush head with a front surface. The front surface may include one or more openings configured to dispense a fluid flowing through a passage within the removable brush attachment. The toothpaste cartridge having a flexible cylindrical tank configured for storing the fluid, and to release the fluid into the one or more conduits when a pressure may be applied to the toothpaste cartridge by the servo mechanism.

A teeth cleaning travel kit includes toothbrushing mouthpiece that has two inverted channels dimensioned to receive upper and lower bites of dental arches of a user, the channels being integral with one another. Teeth-cleaning bristles inwardly project within the two inverted channels to bear inwardly against teeth and gums of the user, wherein the channels and teeth-cleaning bristles are configured such that mastication produces relative brushing movement of the teeth-cleaning bristles over the teeth and gums. An oral hygiene promoting product is attached to one of the two inverted channels and the teeth-cleaning bristles that is released by action of the user's mouth. The teeth cleaning travel kit also includes a vessel that contains a rinsing fluid and kit packaging that contains the toothbrushing mouthpiece and vessel.

A cleaning care appliance comprises a transducer comprising a drive shaft and magnets arranged on the left and right sides of the longitudinal axis of the drive shaft. The magnets are independent of each other, the polarity of the magnetic pole of one side of the magnet is opposite to that of the other side in the direction facing driving coil, the angle between the direction of magnetic force lines inside the magnets and the direction of the longitudinal axis of driving coil iron core is greater than 45 and smaller than 135, the magnets move with respect to the elastic element retainer. When alternating current flows through the drive coil, the angle between magnet movement direction and the longitudinal axis of the core is greater than 170 and smaller than 190. The appliance has low cost, low noise, low damping, and is safe, and reliable.

The invention relates to an electric toothbrush handle and an electric toothbrush. The electric toothbrush handle comprises: a shell, in the inner cavity of which at least one light emitting element is arranged; and a shading part, comprising a light transmission plate arranged on the periphery of the at least one light emitting element, and a first coating arranged on the outer surface and/or the inner surface of the light transmission plate; wherein a light transmission area in a set shape is formed at a position corresponding to each light emitting element in the first coating; and the light of the light emitting element is capable of penetrating through the light transmission area so that the shape of the light transmission area is visible via the shell. The electric toothbrush handle can avoid damage and even failure of a display mark due to wear thereof.
