It is to be understood that not necessarily all such advantages may be achieved in accordance with any particular embodiment of the invention. The distal end portion of the positioning member may include one or more openings that permit the deflected liquid to exit the positioning member and interact with the surrounding environment in the tooth.

The system 38 may include additional and/or different components and may be configured differently than shown in FIGURE 2. For example,, the system 38 may include an aspiration pump that is coupled to the handpiece 50 (or an aspiration cannula) to permit aspiration of organic matter from the mouth or tooth 10. In other embodiments, the system 38 may comprise other pneumatic and/or hydraulic systems adapted to generate the high-velocity beam or jet 60. Also, certain embodiments of the system 38 may utilize or be configured similarly to embodiments of the apparatus and systems described in U.S. The high-velocity liquid beam may generate a pressure wave that can propagate through the tooth and root canal system and can detach or dissolve organic and/or inorganic material from dentinal surfaces and/or dissociate pulpal tissue. The disclosed apparatus and methods advantageously may be used with root canal cleaning treatments, for example, to efficiently remove organic and/or inorganic matter from a root canal system.

The acoustic energy may be sufficient to cause organic and/or inorganic material in the tooth to be detached from surrounding dentin. Without subscribing to or requiring any particular theory or mode of operation, it is believed that a nozzle 64 configured to produce a CC jet may create a higher power acoustic field (e.g., pressure waves) in a tooth (e.g., in dentin or in liquid in the pulp cavity) than a nozzle 64 that is configured not to produce a CC jet.
62, which is configured to hold a nozzle 64. The nozzle mount 62 may be tightly screwed into the distal end 58 of the barrel 52 to secure the nozzle 64 adjacent to a distal end of the passageway 52. As will be described with reference to FIGURES 11A-11C, the nozzle 64 can be disposed in different locations in other embodiments of the handpiece. FIGURES 4 and 4A are cross-section views schematically illustrating another embodiment of a handpiece that can be used to deliver the high- velocity liquid jet. In some embodiments, the disclosed apparatus and methods utilize a high- velocity collimated beam of liquid to clean the root canal system, to clean tooth surfaces (e.g., to treat dental caries), etc. FIGURE 2 is a block diagram schematically illustrating an embodiment of a system adapted to produce a high- velocity liquid jet. FIGURES 19A-19E each include a perspective view (upper figure) and a cross-section view (lower figure) taken along the line 19-19 of the upper figure schematically illustrating an embodiment of a guide tube.
In some embodiments, the distal end 58 of the handpiece 50 may include additional components, for example, to assist guiding or directing the jet 60 and/or to provide aspiration. In some embodiments, the user interface 53 may include controls for a dental practitioner to operate the liquid jet apparatus. The pump 46 can pressurize fluid received from the fluid source 44. The pump 46 may comprise a piston pump in which the piston is actuatable by the motor 40. The high-pressure liquid from the pump 46 can be fed to the pressure sensor 48 and then to the handpiece 50, for example, by a length of high-pressure tubing 49. The pressure sensor 48 may be used to sense the pressure of the liquid and communicate pressure information to the controller 51. Posibles causas de dolor de rodilla . The controller 51 can use the pressure information to make adjustments to the motor 40 and/or the pump 46 to provide a target pressure for the fluid delivered to the handpiece 50. For example, in embodiments in which the pump 46 comprises a piston pump, the controller 51 may signal the motor 40 to drive the piston more rapidly or more slowly, depending on the pressure information from the pressure sensor 48. In some embodiments, the pressure of the liquid that can be delivered to the handpiece 50 can be adjusted within a range from about 500 psi to about 50,000 psi (1 psi is 1 pound per square inch and is about 6895 Pascals (Pa)).
