摘要： A scaffold for regenerating a pulp of a root canal includes a body that has a pre-formed contour that closely matches a contour of the root canal. A method of making a customized regenerative scaffold includes generating a three-dimensional image of a root canal. The method also includes manufacturing the customized regenerative scaffold based on the three-dimensional image of the root canal.

摘要： The applicator tip for root canal sealer is used to coat walls of a root canal with root canal sealer prior to filling the root canal with a filler material. The applicator tip is formed from a hollow shell having a connection portion and an application portion. The connection portion is adapted for connection to a supply of root canal sealer, such as a source of pressurized adhesive cement or the like. The application portion has a proximal end and a distal end, a diameter of the application portion continuously decreasing from the proximal end to the distal end. A plurality of recesses are defined in an outer surface of the application portion of the hollow shell, and a plurality of radially spaced frustoconical openings extend through the application portion of the hollow shell, such that each of the openings is centrally located within a corresponding one of the recesses.

摘要： A disposable, self-inflatable, matrix (tooth dam) used to form a temporary, removeable side wall for the placement of a tooth filling material. It has an array of three concavities (distal, central and proximal) formed in a polymer wrap that has a planar substrate sheet affixed across the front face of the wrap. The distal air chamber has a volume that equals or exceeds the combined volume of the central and proximal air chambers. Directly below the distal concavity on the inner face of the planar substrate is an adhesive region. When the distal air chamber is depressed, the air within inflates the other air chambers and it is retained in its compressed state by the adhesive region. The remaining air chambers press against one tooth and exert enough force to elastically secure the planar panel around the adjacent tooth. It prevents the tooth filling material from leaving the prepared tooth and entering the space between.

摘要： A natural and sustainable material is derived from the nut of the tagua palm tree that may be fashioned into devices for humans and animals. A pulverized and reconstituted material is disclosed herein that is also treated with a low temperature atmospheric plasma treatment. In an embodiment, a biocompatible carrier gas is ionized to form a biocompatible atmospheric plasma stream. Material, such as nano-scale powdered hydroxyapatite, is introduced into the plasma stream, which is then applied to the natural nut material.

摘要： The root canal filling material marker is a tool for marking a desired length on root canal filling material, such as a conventional gutta percha point. In use, the gutta percha point is inserted into a hollow housing through an aperture formed in a front wall thereof. The gutta percha point is releasably gripped between spring-biased clamp jaws. A shaft is longitudinally positioned to a desired marking point at a desired length of the gutta percha point and then laterally pulled. Laterally pulling the shaft slides an applicator, which is secured to the shaft within the housing, across a marking agent and the gutta percha point to make a laterally extending mark on the gutta percha point at the desired length.

摘要： Apparatus and methods for endodontic treatment of teeth provide effective cleaning of organic material (such as pulp and diseased tissue) from the root canal system. In an embodiment, a compressor system generates high pressure liquid (e.g., water) that flows through an orifice to produce a high-velocity collimated jet of liquid. The high-velocity jet is directed toward a surface of a tooth, for example, an exposed dentinal surface, and impingement of the jet onto the surface generates an acoustic wave that propagates throughout the tooth. The acoustic wave effectively detaches organic material from dentinal surfaces and tubules. The detached organic material is flushed from the root canal system by the liquid jet and/or by additional irrigation.

摘要： A pen-like dispenser for dispensing a dental material has a handle and a cover which are attached for rotation relative to each other about a longitudinal axis of the dispenser, and a cartridge for holding the dental material and a screw plunger for extruding the dental material from the cartridge by screwing action. The cartridge and the cover in combination form a rotary slide valve which is operable by rotation about the longitudinal axis between a storage position, in which the cover closes a dispensing outlet of the cartridge, and a dispensing position, in which an opening in the cover opens the dispensing outlet of the cartridge. A relative rotation between the screw plunger and the handle about the longitudinal axis is restricted, and a relative rotation between the cartridge and the cover about the longitudinal axis is enabled within a predetermined rotation angle and restricted otherwise.
