    摘要: A device is described which is useful for providing a dedicated access channel to the root canal of a tooth. The device, which is the frustum of a cone, has a hollow interior passageway adapted to receive and loosely accommodate the shank of a standard assortment of endodontic files. The vertical length of the cone is approximately 10 mm to 15 mm. The wider end of the conical device has an outer diameter of approximately 2.5 millimeters. In practice, the orifice of a root canal is exposed by drilling an access cavity. An appropriately sized endodontic file is selected which will fit within the orifice of the canal. The conical device is slid over the endodontic file until the wider end of the cone is adjacent to the file handle. The file tip is then inserted into the root canal, and the conical device is slid down the shaft of the file until it is brought to bear against the floor of the access cavity with the narrow end of the conical device juxtaposed to the exposed orifice of the root canal. A projected canal matrix material is carefully injected around the endodontic file and the entire access cavity is filled with a suitable self-curing matrix material, such as glass ionomer, to the biting surface. After the matrix solidifies, the file and conical device are removed leaving a conical access channel to the canal orifice.

    摘要: The present invention relates to a method for retaining a passive post and reinforcing endodontically treated teeth by coating a passive metal post with silicone and then with a resin coating, forming a post canal in a cavity, irrigating the post canal with a solution of Ethylene Diamine Tetracetic Acid, irrigating the post canal with Sodium Hypochloride, evacuating the post canal with a high vacuum suction tip, mixing and adding a cement comprising Bis-GMA and TEGDMA to the post canal, distributing the cement with a Lentulo spiral, inserting the silicoated metal post into the post canal, and holding the metal post under pressure until the cement sets. The invention also relates to vacuum apparatus for evacuating a post channel and dentinal tubules of moisture and to create an empty intertubular zone. The vacuum apparatus includes a vacuum suction tip having an outer diameter less than the inner diameter of the post channel and a high vacuum source connected to the vacuum tip. The invention further relates to a hexagonal shaped, parallel sided passive post. Surprisingly, the body of the remaining tooth structure is reinforced up to 30.3% and retention values similar to active posts are achieved by the method according to the claimed invention.

    摘要: The invention achieves its purposes with a grommet thimble incorporating a bore sleeve which may be fitted with retainer means for a sanitary dam. When this thimble is fitted into the specially-prepared entrance portion of a root canal, the retainer means extends from the tooth for holding a dam of rubber or the like without injury to surrounding gingiva during placement of a clamp for the rubber dam. The root canal can be prepared with the sleeve and dam in place, the sleeve and dam serving to facilitate the establishment and maintenance of a sterile field of operation without creation of unnecessary lacerations on the surrounding gingiva. After completion of the desired preparation procedure, or of partial completion, a temporary plug can be removably fitted into the sleeve protection of the work done or in process. For completion of a restoration several options are available. The retainer means can be left in place and used to anchor a core with or without a post. Alternatively a post can be fastened (e.g. screwed) into the sleeve, with or without keeping the retainer means.

    摘要: Apparatus for the determination and the digital display of the position in the tooth canal of a root treating device, comprises a saliva suction device in circuit with the root treating device to sense the variation of the impedance between the gum and the root treating device. That impedance varies inversely as the depth of the root treating device; and so the variations in impedance are amplified and converted into DC voltage levels which are applied to a series of light displays in such a way that one light display will be most brightly illuminated while its neighbors will be less brightly illuminated, the comparative illuminations of the adjacent light displays giving a quick visual indication of the position of the root treating device in the tooth canal. An audible signal can also be provided.

    摘要: A device and procedures for endodontic therapy. An elongated flexible tubular member having a plurality of axially directed orifices formed in the distal end thereof has the proximal end thereof adapted to be connected to a source of supply of liquid. The liquid may be chemically active against necrotic tissue such as a solution of sodium hypochlorite. The distal end of the device is inserted into a root-pulp channel during a root canal procedure and liquid is delivered laterally against the walls of the channel thereby performing a mechanical scrubbing action and providing chemical action. The distal tip of the tubular member is closed off so as to prevent any liquid being expressed directly upon the root apex.

    摘要: A successive delivery multiple barrel syringe includes a body which contains a pair of bores, each of which contains a plunger and each of which leads to a one-way valve and then to a single needle which is mounted on the body. Depressing the plungers in turn, pressurizes fluid placed in the bores which flows from the bores, through the one-way valves and finally through the needle. Mixing of fluids within the device is made negligible by the use of the one-way valve, and by the provision of small conduits which lead from the one-way valves to the needle.
