| 12 | Dedicated channel for root canal access | US525389 | 1995-09-08 | US5658149A | 1997-08-19 | C. John Munce |
| 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. | ||||||
| 13 | Dental irrigating and aspiration system | US400472 | 1995-03-08 | US5540587A | 1996-07-30 | Oscar Malmin |
| A dental irrigating and aspirating instrument utilizes a cannula with a reduced diameter extended member shaped to occlude the apical foramen while conducting irrigating fluid into the apical terminations of root canal preparations. The extended member also serves to occlude the apical foramen while conducting fluid and debris out of the apical regions during aspiration. The extended member can be shaped with a cutting surface to prepare a base for the root canal preparation and root canal filling. Use and fabrication of the instrument for irrigation and aspiration of the fullest depths of the gingival sulci and periodontal pockets in periodontic practice is also described. A handpiece is described that retains the instrument allowing manipulation of the instrument and control of fluids to and from the instrument. | ||||||
| 14 | Appliance for apicoectomy | US33192 | 1993-03-16 | US5409378A | 1995-04-25 | Yango Pohl |
| In apicoectomies, which are carried out after reaming out a bone cavity, treatment of a root is very often necessary. The corresponding fillings must be dry, and thus material separation of the exposed bone surface from the resection area is necessary so that no blood can enter the root region to be filled and, on the other hand, solid particles and any reagents which are necessary (for example for root canal irrigations) are unable to contact the bone cavity. An appliance is provided to allow complete lining of the bone cavity and to separate the latter materially from the root region to be filled. The lining has two layers of different and complementary function. The lining is pushed into the bone cavity using a suitable tool and, at the same time, is shaped to the surface of the cavity. | ||||||
| 15 | Method to reinforce endodontically treated teeth and passive post | US933 | 1993-01-05 | US5326264A | 1994-07-05 | Raed Al Kasem |
| 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. | ||||||

| A method for treatment of periodontal disease is disclosed. The gingival tissue is separated from the tooth surface in an area where periodontal disease is present. A biocompatible, porous material such as expanded polytetrafluoroethylene capable of supporting ingrowth of gingival connective tissue and preventing apical migration of gingival epithelium is placed in a laminar relationship to a portion of the perimeter of the tooth surface. The gingival tissue is repositioned around the tooth and in contact with the porous material, with the porous material positioned between the gingival tissue and the tooth. Articles for the treatment of periodontal disease are also disclosed. One article comprises a first portion which is capable of supporting ingrowth of gingival connective tissue and preventing apical migration of gingival epithelium and a second portion which is impermeable to oral tissues and bacteria. | ||||||
| 20 | Thermoelectric ion generator for endodontic therapy | US279110 | 1988-12-02 | US4886075A | 1989-12-12 | J. Paul Jones |
| A thermoelectric anti-bacterial ion generator device, which is needle-like in appearance, and fits into root canals of teeth that are undergoing endodontic therapy. The miniature ion generator focuses a field of positive silver ions on the apex of the tooth root, and on the root membrane; which destroys bacteria in the infected area and enhances the regeneration of new bone and tissue. The generator has a small loop at the top, which enables it to be easily removed after the initial treatment period; or it may remain in the root canal when the tooth cavity is filled, to prevent reoccurrence of infection. | ||||||
