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.

The present disclosure relates to a patient anxiety management system for managing patient anxiety during a dental procedure. In one example, a patient anxiety management system is presented. The patient anxiety management system includes a control module that a patient can use to disactivate a medical device used by a dental professional by way of a trigger mechanism. Upon deactivating the medical device, a recording device, in communication with the control module, plays a recorded message to the patient during a programmable timeframe. Once the patient is calm, the system resets the medical device to an initial operation state by reconnecting but not reactivating the medical device so that the dental professional may resume the procedure when it is safe to proceed.

A laser-assisted ridge preservation method is performed using a free-running (FR) pulsed neodymium yttrium aluminum garnet (Nd:YAG) laser device. The method includes one or more of photothermally denaturing and vaporizing encapsulated granulomatous tissues with the laser device on all sides of a socket of an extracted tooth, and irradiating the socket with the laser device to form a thrombus. A bone graft material may be placed into the thrombus.

A sensing system includes laser diodes with Bragg reflectors generating light having an initial light intensity and one or more near-infrared optical wavelengths. The laser diodes are modulated with a pulsed output with 0.5 to 2 nanosecond pulse duration. A beam splitter receives light from the laser diodes, splits the light into a received sample arm light directed to an object and a received reference arm light. A detection system includes a second lens and spectral filters in front of a photodiode array. The photodiode array is coupled to CMOS transistors and receives at least a portion of the received reference arm light and generates a reference detector signal. The detection system is synchronized with the laser diodes. A time-of-flight measurement is based on a comparison of the sample detector signal and the reference detector signal and measures a temporal distribution of photons in the received reflected sample arm light.

A dental laser comprises a hand piece having a grip region and a treatment tip with an outlet point, arranged at a distal end, for laser light, and further comprises a light source and light conduction means for providing laser light at the outlet point. The laser light has a wavelength of 44520 nm, in particular, 44510 nm and more particularly 4455 nm, and an optical power output is provided at the outlet point in a power range of at least 2 W, advantageously at least 3 W and, in particular, 3.5 W. In another dental laser the laser light has a wavelength of 41010 nm, and an optical power output is provided at the outlet point in a power range of no less than 1 W to no more than 2 W.

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 central display and an outer display with selectable segments, and a menu navigation portion located adjacent the outer 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.

An automated dental drill includes a dental drill housing that includes a mouthpiece housing section and a one or more degrees of freedom drive housing section; an end effector drive support having a shaft section that is at least partially positioned in the mouthpiece housing section, and an end effector for the cutting of a native tooth or dental appliance to a desired tolerance. The end effector is positioned on the end effector drive support. The automated dental drill also includes a power source that drives the end effector and is coupled to the end effector and a one or more degrees of freedom drive assembly to direct the end effector along one or more degrees of freedom relative to the mouthpiece housing section.

A peeling type laser tooth preparing method, apparatus and device, and a medium. Method comprises: acquiring a first STL model of a target tooth and a second STL model of a tooth preparation of the target tooth; generating a conical peeling curved-surface STL model, in a manner of taking a three-dimensional curve of a peripheral edge contour of a shoulder in the second STL model as a bottom edge; carrying out Boolean calculation on the peeling curved-surface STL model and the first STL model to obtain a third STL model; carrying out Boolean calculation on the second STL model and the third STL model to obtain a fourth STL model required to be removed; generating a multilayer laser cutting path according to the fourth STL model, controlling a laser tooth preparing device to perform the tooth preparing process of the target tooth according to the multilayer laser cutting path.

A system and method for dental or surgical treatment of oral tissue, the system including a laser source; a hand piece; and a device for directing radiation emitted by the laser source to a treatment area (e.g., an oral treatment area), the device further including a disposable tube attachable to the hand piece and an optical element (e.g., a substantially cylindrical lens) mounted within the disposable tube and adapted to modify a profile and/or a direction of the radiation emitted from the tube.

An improved dental laser system has been developed to cut enamel quickly and precisely, without detrimental residual energy, to provide a replacement for conventional high speed rotary burrs and commercially available dental laser systems.
