| Examples of apparatus, methods, and compositions for endodontic treatments are described. The apparatus can include a fluid platform configured to substantially retain fluid in a tooth chamber during treatment. The fluid platform can help maintain fluid circulation in the tooth chamber as fluid flows into and out of the tooth chamber. The apparatus can also include a pressure wave generator configured to generate acoustic waves that can be used for cleaning root canals and tooth surfaces in the tooth chamber. Examples of pressure wave generators include a liquid jet, an electromagnetic energy delivery device, and an ultrasonic device. The fluid can include antiseptic or antibacterial solutions to assist in tooth cleaning. The fluid may be degassed to have a reduced dissolved gas content (compared to non-degassed fluids used in endodontic treatments), which may improve the effectiveness of the pressure wave generation or the cleaning. | ||||||

| Systems and methods are provided for cleaning or disinfecting a target region. A fluid including a plurality of gas bubbles is placed into an interaction zone. The interaction zone is a volume that extends into the target region or that is adjacent to the target region. The fluid in the interaction zone is exposed to electromagnetic radiation, where the electromagnetic radiation has a wavelength that is substantially absorbed by the fluid. The fluid in the interaction zone substantially absorbs the electromagnetic radiation to create an acoustic shock wave and a pressure wave. The acoustic shock wave and the pressure wave cause a movement of the fluid and cavitation effects that are configured to clean or disinfect the target region. | ||||||

| A method and system for inserting a dental post into a tooth root canal. The method comprises the steps of cutting out a post hole in the tooth and inserting a threaded tap into the post hole for creating at least one groove along the hole. Significantly, the tap includes at least one slot defined by a pair of flexible legs and running at least a portion of the length thereof for reducing stress along the post hole during threaded insertion. Also provided is a lentulo drill comprising a spiraled wire with a reverse spiral configuration at the apical end thereof for confining cement placement in the post hole prior to insertion of the dental post. | ||||||
| 57 | Hydraulic endodontia device | US498349 | 1995-07-08 | US5575657A | 1996-11-19 | Sidney E. Welch |
| A hydraulic endodontia device and method comprised of a primary obturator rod having an objective tip end with at least one spill gate integrally formed therewithin and a handle end, the primary rod being generally cylindrical in shape and gradually diminishing in circumference from the handle end to said tip end. The invention is further defined by a plurality of secondary obturator rods each having an exterior convex side and an interior concave side. The interior concave side of each secondary rod glides upon the primary rod or the exterior convex side of an underlying secondary rod in cooperative association therewith when the open spill gate, the primary rod is inserted into the extirpated root canal until it reaches the distal end at the tip end, whereby narrowing of the distal root canal end constricts the spill gate to effuse cement to the apical area. Additional cement is applied to a plurality of secondary rod interior concave sides which are then inserted within the canal one rod at a time in cooperative association with the primary rod until complete obturation is achieved. | ||||||
| 58 | Dental irrigating and aspiration system | US242879 | 1994-05-16 | US5490779A | 1996-02-13 | 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. | ||||||
| 59 | Dental instrument with microwave/RF radiation and method of treating a tooth | US74652 | 1993-06-07 | US5421727A | 1995-06-06 | Barry H. Stevens; Arye Rosen; Kevin W. Choi |
| Dental or endodontic instruments such as drills, files, rasps, broaches, reamers, and the like are arranged to allow radiation of electromagnetic energy into a man-made or natural cavity in the tooth under treatment. The energy may be in the form of microwave or radio-frequency (RF) radiation. The energy raises the temperature of the surrounding tooth material, which tends to disinfect the material as a direct consequence of the temperature. Also, if a disinfectant material is additionally introduced into the tooth cavity, the temperature of the disinfectant material itself may be raised, which enhances its activity. In the particular application to the removal of degenerated pulp, the instrument may be introduced, and electrical or electromagnetic power applied to coagulate the pulp about the instrument, allowing more complete removal of the pulp. The dental instrument may be used with an RF energy delivery system for application of particular amounts of energy per unit time (power). The RF power may be carried through miniature coaxial cables through the dental instrument itself, to enable radiation directly into the interior of the tooth. For this purpose, in some embodiments of the invention the dental instrument includes a portion formed from a dielectric material which allows the energy to pass therethrough. In a particular embodiment, a dental drill includes an antenna near the distal end thereof, a capacitive top cap of which is made from hardened material shaped for removal of tooth material. | ||||||
| 60 | Syringe for washing teeth root canals | US817554 | 1992-01-07 | US5171146A | 1992-12-15 | Sergio Guerci |
| A syringe useful for washing root canals wherein the syringe is configured and arranged with a two-position valve which, in a first position, supplies the syringe with hydrogen perioxide and, in the second position, supplies the syringe with sodium peroxide. In a selected embodiment, the valve has a single outlet port and first and second inlet ports connected to a hydrogen peroxide and sodium peroxide supply, respectively. The outlet port is connected to the inlet ports by a rotatable obturator having first and second slanted grooves having first and second ducts, respectively, at opposite ends thereof. In a first rotatable position of the obturator, the first groove is aligned with the first inlet port, and the first duct is aligned with the outlet port. In a second rotatable position of the obturator, the second groove is aligned with the second inlet port, and the second duct is aligned with the outlet port. | ||||||
