A device and means to decrease the pain associated with dental procedures as from dental drills, the probing scratching tool to detect cavities, the needle to inject anesthesia, the tool to extract nerve for root canal treatment, etc. The device uses electrical currents of both positive and negative polarity or alternating current.

A dental caries diagnosis device comprising a light source which is configured to emit examination light (R) and a light receiving unit (4f) which is configured to receive the examination light (R) with which a tooth has been irradiated includes: a head-side casing (4a1) which is inserted into a mouth in a contactless manner with respect to a tooth or a gum and which projects the examination light (R) toward a tooth; and a filter (4e) which is disposed in front of the light receiving unit (4f) and which is configured to remove a noise component from the received light, wherein the light receiving unit (4f) is configured to receive the examination light (R) which has been transmitted through the tooth.

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.

Embodiments of the invention include a handpiece system including a detachable cable that can receive at least power, and a detachable cable connector, where the detachable cable connector and detachable cable are reversibly attachable to each other. In some embodiments, the system includes an interchangeable laser module, where the laser module and detachable cable connector are reversibly attachable to each other. Further, the interchangeable laser module is configured and arranged to receive at least the power via the cable connector when coupled to the cable connector, and to be removed from the detachable cable connector and replaced with another laser module. In some embodiments, the system further includes an interchangeable handpiece which is reversibly attachable to the interchangeable laser module. Further, the interchangeable handpiece is configured and arranged to be removed from the interchangeable laser module and replaced with another interchangeable handpiece.

An intraosseous tack device is configured to puncture alveolar bone or other human or animal bone at a targeted site of the mouth or body to provide an access point for the delivery of local anesthesia or other medicament. The device includes a tack having a head member and an elongate member extending from the head member. The elongate member is inserted into a sleeve, and the sleeve is coupled to a handle. At least a portion of the sleeve is collapsible, so that when a compressive force is applied to the head member of the tack, the sleeve partially collapses to a shorter length, allowing the distal end of the tack to pass out of the opposite end of the sleeve for puncturing the alveolar bone at the targeted site.

The present invention relates to a maxillary teeth orthodontic device capable of correcting upper jaw molars and anterior teeth by moving the upper jaw molars and the anterior teeth in forward and backward directions. The maxillary teeth orthodontic device comprises: a body attached to the bottom surface of the gums of the upper jaw; a connection leg of which one end is connected and extended from the body; a molar fixing part connected to the other end of the connection leg and fitted into a molar; and a ring part connected to one side of the lower surface of the body, wherein the body is divided into a first body and a second body such that gaps are adjusted by allowing the first body and the second body to be spaced from each other or approach each other in the incisor direction and the airway direction of the upper jaw.
