An oral care implement having a multi-component handle. The oral care implement may include a head and a handle. The handle may have a front surface, a rear surface, and opposing first and second lateral surfaces. The handle may include an elongated handle body, a grip cover, and a transparent component. The elongated handle body and the grip cover may be opaque. The elongated handle body may form a portion of the front surface of the handle and the grip cover may form a portion of the rear surface of the handle. The transparent component may form a portion of each of the first and second lateral surfaces of the handle. Thus, the transparent component may form a window through the lateral surfaces of the handle.

A oral hygiene tool has a tongue scraper and a toothbrush. The tongue scraper includes an elongate connector body, a scraper blade being on a first end transverse to the elongate connector body. A slide control mechanism extends from a second end of the elongate connector body. An interlocking structure has a laterally extending ridge. The toothbrush includes an elongate toothbrush body that has a plurality of brushes and a bore that extends into a distal end of the elongate toothbrush body. A slot extends longitudinally along part of the elongate toothbrush body into the bore, while first and second lateral grooves extend laterally into the slot. The interlocking structure is adapted to be slidably inserted into the bore of the elongate toothbrush body such that the interlocking structure is pushed outwardly into the slot of the elongate toothbrush body.

A combination includes a dental handpiece and a prophy angle. The dental handpiece includes a nosecone threadably connected to the dental handpiece. The prophy angle includes a proximal body that matingly attaches to the nosecone. A plurality of elongated torque members are formed on each of the prophy angle proximal body and the nosecone. Each of the torque members is a male torque member or a female torque member and each male torque member formed on one of the prophy angle proximal body and the nosecone matingly couples with a female torque member formed on the other of the nosecone and the prophy angle proximal body. The prophy angle, including the plurality of elongated torque members formed on the prophy angle, is formed to also be attachable to a known standard doriot-style nosecone. Other specific features of the handpiece and prophy angle are also disclosed.

The invention provides a unitary cordless dental drive apparatus in a first embodiment having a handpiece with a cantilever arm 18 extending outward and positioned to allow a dental nose cone 26 to be connected. An activating switch 20 is located at the free end of the cantilever arm 18 in a position that is convenient for manipulation by a user. In a second embodiment, a contactor 22 is mounted below the cantilever arm 18 to contact the nose cone 26 when pressed. In a third embodiment, a standard dental office foot pedal 90 is connected to a wireless transmitter 80 for sending a signal to a receiver 92 located within the handpiece 70 for activating the handpiece 70.

A cartridge and a base unit for use in an oral care appliance are disclosed. The cartridge includes a connection interface configured to form a detachable connection. The base unit is also configured to engage operatively with the cartridge to facilitate flow of an oral care composition from the cartridge into the oral care appliance.

The present invention involves a cleaning sleeve for cleaning the oral cavity, suitable to be applied over a finger or a tool to clean the inside of the oral cavity. The cleaning sleeve has a flat-layered structure comprising a sleeve portion formed by laminated sheet-like fabrics and a grip portion formed by a single-layer sheet-like fabric, wherein the sleeve portion comprises a working layer and a sleeve layer; the working layer and the sleeve layer form a head at the top, of the cleaning sleeve; and the grip portion is integrally extended from the Working layer. The cleaning sleeve is formed by ultrasonically bonding the two sides of a piece of folded degradable nonwoven fabric.
