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： Apparatus and methods for monitoring a tooth may include sensing acoustic energy propagating from regions (such as a root canal system) in and/or near a tooth. The apparatus and methods may be used with root canal cleaning treatments to determine the efficacy of the treatment and/or to reduce risk of post-treatment complications. An acoustic source (e.g., an acoustic transducer and/or a high-speed liquid jet) may be used to transmit energy into a tooth and/or regions near a tooth. An acoustic receiver may be used to detect acoustic signatures of acoustic events (e.g., acoustic echoes and/or acoustic cavitation) occurring in the tooth. The acoustic signatures may be used, for example, to determine the progress of a root canal cleaning treatment and/or the presence or movement of material toward a periapical region of the tooth. Apparatus and methods for monitoring a tooth may include detecting impact of a first jet on a tooth and actuating a second jet in response to detection of the impact.

摘要： Apparatus and methods for root canal treatments are provided. In some embodiments, an aiming element may be used to position a high-velocity liquid jet near a desired location in the tooth. Embodiments of the aiming element may include an interrupter that deflects or impedes the liquid jet when it is not desirable for the jet to propagate from the aiming element. Embodiments of the aiming element may include an elongated member that permits passage of the liquid jet through a channel. The elongated member may include one or more openings, for example, on sides and/or ends of the member. Some root canal cleaning techniques include one or more applications of the liquid jet followed by application of a disinfectant such as, for example, an aqueous solution of sodium hypochlorite.

摘要： 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. An access opening can be formed, and the pressure wave generator can be used to remove organic material from the tooth chamber. In some treatments, after cleaning, the tooth chamber can be only partially filled by an obturation material. In other treatments, substantially the entire tooth chamber can remain unfilled by the obturation material. After cleaning the tooth, the access opening can be sealed, using, e.g., a coronal seal.

摘要： Systems and methods for using a liquid jet apparatus for dental treatments are disclosed. In one implementation, the liquid jet apparatus may include a handpiece configured to deliver a high velocity liquid jet to a desired location in the mouth of a patient. The handpiece may include a positioning member having a channel through or along which the jet can propagate. The positioning member may have a distal end portion configured to be at least partially disposed in a pulp cavity, canal space, or opening in the tooth under treatment. During operation, the jet may impact an impingement surface of the distal end portion of the positioning member and be deflected as a spray through one or more openings in the distal end portion. The liquid jet apparatus may be used for root canal treatments.

摘要： In various embodiments of a method for filling root canal spaces, the root canal spaces are cleaned and irrigated, for example, by any suitable endodontic procedure, and the irrigating liquid is not removed from the canal spaces prior to filling. In some embodiments, a hydrophobic filler material is introduced into the root canal spaces while they are filled with liquid. As the canal spaces are filled, the hydrophobic filler material displaces the liquid and drives it out of the canal spaces, towards the crown of the tooth, where it can be removed. The hydrophobic filler material may comprise magnetically responsive particles having a hydrophobic surface coating that are compacted into the root canal spaces by application of a magnetic force field. In other embodiments, hydrophilic filler material in a flowable phase is introduced into the canal spaces where it partly displaces and partly absorbs the irrigating liquid before solidifying.
