The invention provides a unitary cordless dental drive apparatus with a cantilever arm extending outward and positioned to allow a dental nose cone to be connected. An activating switch is located at the free end of the cantilever arm in a position that is convenient for manipulation by a user. In a second embodiment, the switch is in the form of a contactor mounted below the cantilever arm to contact the nose cone when pressed. In a third embodiment, a foot pedal connected to a wireless transmitter is provided to send a signal to a receiver located within the handpiece for activating the handpiece.

Provided is a teeth cleaning device that includes a gel cartridge, a plurality of light emitting diodes, a mouth guard, and a controller. The cartridge stores a gel. The light emitting diodes emit a cold light. The mouth guard has a generally arcuate shape and includes a first recess, a second recess opposite the first recess, a cavity, a first surface, and a plurality of first openings. The first recess is located on a top side of the guard to receive a first row of teeth, and the second recess is located on the bottom side of the guard to receive a second row of teeth. The cavity is between the first recess and the second recess. The first surface is in communication with the cold light of the light emitting diodes. The assembly has a generally arcuate shape and is disposed in the cavity of the guard between the first recess and the second recess. The assembly includes a plurality of vibration motors and a plurality of second openings, wherein the motors are configured to generate vibrations and the second openings are in communication with the first openings. The controller is configured to control dispensing the gel from the gel cartridge through the second openings and the first openings into a user's oral cavity, emitting the cold light from the light emitting diodes through the mouth guard into the user's oral cavity to activate a whitening compound in the gel, and vibrating the plurality of vibration motors configured to drive the gel against surfaces of the first row of teeth and the second row of teeth.

In one embodiment, the invention may be a teeth cleaning device including: a first support structure comprising a first dentature channel configured to receive at least a first portion of a dentature of a user; a plurality of teeth cleaning pads located within the first dentature channel; a plurality of air bladders operably coupled to the teeth cleaning pads; an air-flow subsystem operably coupled to the air bladders; and a control unit operably coupled to the air-flow subsystem, the control unit configured to: (1) pressurize the air bladders with external air in a pressurization mode; and (2) transfer air between select ones of the air bladders in a cleaning mode.

The present invention relates generally to a system and method for measuring the structural characteristics of an object. The object is subjected to an energy application processes and provides an objective, quantitative measurement of structural characteristics of an object. The system may include a device, for example, a percussion instrument, capable of being reproducibly placed against the object undergoing such measurement for reproducible positioning. The system does not include an external on/off switch or any remote on/off switching mechanism. The system also includes a disposable feature or assembly for minimizing cross-contamination between tests. The structural characteristics as defined herein may include vibration damping capacities, acoustic damping capacities, structural integrity or structural stability.

A device for testing a heat sensitivity in teeth, a heated cushion for a dental device for testing a heat sensitivity, and a method for testing a tooth for a heat sensitivity.
