Abstract: A dental instrument includes a housing a first part with a circumferential wall and defining a hand-piece for holding, preferably by a single hand, a light source, electrical components for operating the light source, and a tip portion which supports a light guide that receives light from the light source. The housing has between the first part and the tip portion a second part with a circumferential wall having on a first side a first control element for fingertip operation and on a second side a second control element for fingertip operation, the first control element being located circumferentially opposite the second control element.

Abstract: A handset includes a high power LED and a vibrator. An optical tip includes a stepwise tapered portion for insertion into a root canal. The optical tip is used in combination with the vibrator for distributing a photosynthesizer in a root canal. The optical tip is used in combination with the LED for activating the photosynthesizer.

Abstract: An optical tip for disinfecting a site of a periodontal pocket includes a first portion configured to be optically coupled to a light source, and a second portion configured to be introduced into the site of the periodontal pocket, where a distal end of the second portion is cylindrical in form and has a constant outer diameter. The second portion is configured to carry light from the light source to the distal end.

Abstract: An endodontic obturator for filling an endodontically prepared root canal of a tooth. The endodontic obturator includes an elongated shaft of having a proximate portion and a distal portion. The proximate portion has a handle portion connected thereto or is suitable for being releasably connected to a handle portion. A layer of filler material is coated about the shaft. The filler material has a low operating temperature at which it becomes plasticized or partially molten. The filler material in the layer disposed close to the distal end can have a higher viscosity at the operating temperate than the filler material close to the distal end.

Abstract: A body cavity obturator having bismuth particles dispersed therein. Bismuth is dispersed throughout the plastic core or shaft, and/or throughout a filler material disposed thereon to produce a plastic article that presents a clearly defined x-ray image similar to that of a steel implementation thereof.

Abstract: A low level laser therapy (LLLT) system. The laser therapy apparatus comprises a laser head and a detachable battery section. When the laser head is mounted to the battery section the apparatus assumes the shape of a penlight or flashlight and can be used as a handheld laser therapy apparatus. The detached laser heads can be placed and held in apertures of a bandage that is applied to a joint of a patient to be treated for use of the apparatus as a patient worn device.

Abstract: A kit for use by dental professionals comprising a handle part with a proximal end and a distal end and a plurality of user interchangeable electrically operated heads to be attached to the distal end of said handle part. The handle part provides power for any of the heads fitted thereto.

Abstract: A light emitting apparatus for curing a photocurable dental prosthesis in a patient's tooth that comprises a LED carrying part connected to a handle. The LED carrying part comprises a first plurality of LEDs directed to a first side of the tooth, and a second plurality of LEDs directed to a second side of the tooth. The present invention also relates to a method of curing a photocurable dental prosthesis in a patient's tooth, in which a light emitting apparatus is provided that comprises LEDs that are mounted on a substrate, the substrate being covered with a clear coating embedding the LEDs, and the LEDs being placed so proximate to the photocurable dental prostheses that the smallest distance between the outer surface of the clear coating and the outer surface of the photocurable dental prostheses is less than 2 mm.

Abstract: A dental device for applying a thermoplastic filler material comprising thermoplastic gutta percha to a root canal of a tooth. The device comprises an elongated shaft of flexible material having a distal end forming a core for a layer of thermoplastic filler material surrounding at the least distal end said shaft. The layer of filler material comprises an anti-microbiological substance for preventing or at least reducing the risk of irritation, inflammation or infection.

Abstract: A dental device and method are provided for applying gutta percha to a root canal of a tooth. The device includes an elongate filler member made of a biocompatible material capable of being cut so that the length of the filler member can be reduced to a desired length by a user of the device, in accordance with the length of the root canal, prior to insertion of the device into the root canal. A head portion of the filler member is of uniform thickness throughout the length thereof, and a distal end portion is uniformly tapered along the length thereof in a direction away from the head portion such that the filler member is without any discrete area of weakness throughout the length thereof. An outer sheath of thermoplastic gutta percha surrounding a portion of the distal end of the filler member. An indicator at the proximal end of the filler member assists the user in determining the portion thereof to be cut off to achieve the desired length.

Abstract: In an appliance for use in filling an endodontically prepared root canal of the kind comprisinga) a central insertion rod (2) of flexible material, surrounded partly byb) an elongate filler body (3) of plastic or thermoplastic material, the new feature is represented byc) a core (4) surrounding the rod (2) and surrounded by the filler body (3) and consisting of material that is or may be made sufficiently soft to allow removal of the rod (2) without removal of the filler body (3).One advantageous effect of this arrangement is that anchoring holes for a tooth crown may be drilled without risk of encountering a broken-off part of an insertion rod that would previously have been left to remain permanently in the filler body (3).

Abstract: A dental instrument adapted to be used as a file or reamer for removing dead or damaged tissue from the root canal of a tooth. The instrument comprises a body part, of which solely the proximal part is shown, an intermediate part and a shank, these three parts preferably being integral with each other. The shank is adapted to be inserted releasably in a chuck, so that it may be driven to rotation when the instrument is used for treating the root canal of a tooth (not shown). A fracture groove between the intermediate part and the shank ensures that fracture occurs at this location, if the body part gets stuck in a tooth, thus avoiding the risk of small distal parts of the instrument being left in the root canal in a manner making it impossible to remove them.
