A dental valve device having a disposable turret is disclosed having a valve body having a tip receiving end, a hose receiving end, a lumen formed between the tip receiving end and the hose receiving end, an opening formed in the valve body, and a rotatable valve sealing body adapted to being inserted into the opening, the rotatable valve sealing body having a bore for alignment with the lumen formed between the tip receiving end and the hose receiving end, the bore having a tip receiving end opening and a hose receiving end opening, the rotatable valve sealing body having an outer surface having an indentation formed in the outer surface adjacent to the tip receiving end opening with the indentation having an upper ramp portion, a lower ramp portion, and an end having a tab portion.

Embodiments of the invention provide a system of controlling a dental laser system. The system can include a dental laser and a control system for controlling certain functions of the dental laser. A graphical user interface can be used to provide input to the control system. The graphical user interface can include a first display and an second display with selectable segments, and a menu navigation portion located adjacent the second display. Treatment categories, procedures or laser control options can be selected using the interface, and the interface can be updated based on data from the station.

A method for controlling a dental instrument includes a foot pedal responsive to commands from a user. An operating mode is selectable between normal and boost cycle. A conventional mode is selectable by pressing and holding the foot pedal to a first level to operate in normal mode. The foot pedal operates in a boost mode when the pedal advances to a second level. Maintained mode is selectable by tapping the foot pedal to change modes between idle, normal and boost mode. Each mode is switched by tapping the foot pedal. The pedal switches between the second process and the first process by pressing and holding the foot pedal at the desired level corresponding to normal or boost mode. The pedal switches from the first process to the second process by tapping the foot pedal at the level corresponding to normal or boost.

In a dental treatment apparatus, a control circuit controls a drive motor in accordance with a drive sequence. The drive sequence includes a plurality of drive patterns and at least one of the plurality of drive patterns is different from other drive pattern. The plurality of drive patterns include at least one drive pattern having such drive that a cutting tool is rotated in a cutting direction for cutting a treatment portion and drive for rotating the cutting tool in a non-cutting direction which is reverse to the cutting direction.

There is provided an applicator cartridge for delivery of a photoactivatable composition to a treatment site, having an applicator head and a reservoir adapted to receive the composition, which may be used with a photodynamic therapy device comprising an illuminating member. Methods of using the applicator cartridge and the device are also provided.

The invention relates to an apparatus for irradiating an object, in particular for light-curing a dental object by means of a first radiation, the apparatus comprising at least one radiation source for emitting the first radiation, the apparatus further comprising at least one radiation sensor for measuring at least a second radiation, and the apparatus further comprising a housing. The second radiation is the first radiation reelected by the object.

The present invention provides a formulation for increasing the efficiency and safety of cutting a tooth structure during dental procedures. In accordance with one form of the present invention, there is provided a formulation including 10 to 30% by weight of ethanol; 5 to 15% by weight of glycerol; 10 to 20% by weight of xylitol; 0.5 to 5% by weight of a nonionic surfactant and emulsifying agent; 0.15 to 0.5% by weight of a plurality of flavoring agents; and 51 to 77.5% by weight of water.

A control device for controlling a surgical handpiece is suitable for controlling the surgical handpiece according to control parameters. The control device comprises local control means present on the control device, wireless communication means suitable for communicating with remote control means by a wireless communication link. The local control means and the wireless communication means is suitable for receiving instructions to adjust each control parameter. Selector means is provided for selecting either the local control means or the wireless communication means for adjusting each control parameter.

A medical or dental handpiece comprises a lighting device for the emission of radiation, in particular of visible light, onto a treatment site, a temperature sensor preferably located in the interior of the handpiece, and at least one shared electrical signal line provided in the handpiece for the lighting device and the temperature sensor. The lighting device and the temperature sensor are both operatively connected to the at least one shared electrical signal line. A medical or dental treatment device comprises such a handpiece and a control and/or regulation device electrically connected to the at least one shared electrical signal line provided in the handpiece, which is designed to emit a first electrical signal assigned to the lighting device and a second electrical signal assigned to the temperature sensor.

The present invention relates to a device and a method for measuring osseous quality.
