  • Publication number: 20210068921
    Abstract: 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.

  • Publication number: 20200146774
    Abstract: 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.

  • Publication number: 20120276497
    Abstract: 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.
