A system and method for mitigating pain associated with dentistry provides a removal apparatus for removing a portion of a tooth. A desiccation apparatus flows a desiccated gas to the portion of the tooth to desiccate dentinal tubules in a region surrounding the portion of the tooth, generally preventing nerve cells within the tooth from transmitting pain signals associated with the removal. The removal apparatus has a drill head with a body having an axial opening configured to accept a dental burr. An annular passage exists between the dental burr and the body within the axial opening. A chamber in the body is in fluid communication with the axial opening, where a channel is fluidly coupled to an external port and to a source of the desiccated gas to flow the desiccated gas therethrough and expose a drilling region of the dental burr to the desiccated gas to mitigate pain.

An oral care implement herein may be embodied as an oral device for placement in the oral cavity. The device may include an insert configured for placement in the oral cavity in contact with a wearer's teeth and an activating member configured for placement in the oral cavity and selectively attachable to the insert.

The invention relates to a handpiece for simultaneously irrigating and suctioning during an endodontic procedure, the handpiece comprising a handle portion comprising a first fluid line and a second fluid line passing into a head portion comprising an outlet for the first fluid line and an inlet for the second fluid line. The invention also relates to a method of performing a dental procedure such as a root canal. The handpiece permits the procedure of irrigating, cleansing and disinfection to be conducted by a single operator such as an endodontist, a dentist or even a dental student.

To provide an air injection device for a dental handpiece which makes it possible to obtain a clear image even if the position of an image taking part is changed, provided is an air injection device including: a trunk connector (41) that is in a form of a column, in the trunk connector a passage being formed; an air guiding pipe (45) that is in a form of a pipe, one end of the air guiding pipe being connected to the trunk connector, the air guiding pipe having flexibility; and a means (46) that retains the air guiding pipe in the dental handpiece main body, wherein the passage in the trunk connector branches, one of the branching passages communicating with the air guiding pipedental handpiece.

Dental handpieces, motors, couplers and other dental instruments and methods having multiple very small, high output, LEDs in a single lamp assembly to facilitate incorporation of a plurality of wavelengths emitted from these devices to allow dentists to select between the benefits of multiple wavelength light outputs to the working area in a single device.

A dental instrument comprises a fluid driven handpiece in fluid communication with a valve; a source of fluid in fluid communication with the valve; and a controller in electrical communication with the valve and an actuator positioned on the handpiece. The actuator is configured to cause the valve to move between a first position in which fluid cannot flow from the source of fluid to the handpiece and a second position in which fluid flows from the source of fluid to the handpiece thereby driving the handpiece. The dental instrument may further comprise a second actuator in communication with the controller. The second actuator is configured to cause the valve to move between the first position in which fluid cannot flow from the source of fluid to the handpiece and the second position in which fluid flows from the source of fluid to the handpiece thereby driving the handpiece.

Various aspects are directed to dental extraction and dental extraction devices. As may be implemented in accordance with one or more embodiments herein, a dental extraction apparatus includes an engagement component that extracts teeth from patients' mouths by engaging with and applying a torque to a tooth. An input torque component translates received input torque to the engagement component. A torque controller operates with the input torque component and the engagement component to limit the applied torque, relative to input torque provided via the input torque component.

A system for driving an electric handpiece in response to a pneumatic control signal may provide for fast interchange of handpieces, self-calibration and wide dynamic range of operation with precise speed control. The system may be incorporated into virtually any dental treatment center using traditional pneumatic drive handpieces, and a conversion kit may facilitate such conversion. The system may provide not only for controlling the speed and torque of a tool coupled to an electric drive handpiece responsive to a pneumatic control signal, it may also provide for coupling cooling air and treatment media, such as air and/or water to the handpiece. Coupling of a handpiece to an operating base of the system, including coupling of media lines and electrical connections may be made with a simple press and twist action using quick connection structure.

A dental device is disclosed comprising a dental handpiece, a controller including a microcontroller and a foot control pressure sensor, and a foot pedal. The foot pedal is in communication with the controller and controls the dental handpiece. The dental device is arranged to configure between at least two of a speed limiting mode, a feathering mode, and a standard mode. In the speed limiting mode, the controller proportions air flow so as to limit the speed of the dental handpiece to a specified speed. In the feathering mode, the foot pedal proportions air to the controller which then transmits the air to the dental handpiece such that the foot pedal controls the speed of the dental handpiece. In the standard mode, the speed of the dental handpiece is set without limiting by the controller and without feathering by the foot pedal.
