A dental tool includes: a hand piece; an endodontic hand file; a stopper, wherein the stopper comprises a first hole for receiving a portion of the endodontic hand file; and a mechanical motion module that imparts mechanical motion to the endodontic hand file. A dental system includes: a hand piece; an endodontic file; and a stopper comprising at least two holes, wherein a first hole receives a portion of the endodontic file, and wherein a second hole receives a portion of a first tube for delivering a liquid to the endodontic file. The dental system can further include a second tube partially contained in a third hole of the stopper for suctioning liquids from a patient's mouth. The dental system can also further include a mechanical motion module.

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.

A scaffold for regenerating a pulp of a root canal includes a body that has a pre-formed contour that closely matches a contour of the root canal. A method of making a customized regenerative scaffold includes generating a three-dimensional image of a root canal. The method also includes manufacturing the customized regenerative scaffold based on the three-dimensional image of the root canal.

The present invention refers to a plasma jet device (30) for medical treatment of root canals (3) using an atmospheric pressure plasma. The device comprises a handle (40) and a probe (50) with a gas channel (54) and a first and second electrode (31, 32). The probe (50) has a first end connected to the handle (40) and a second end opposite to the first end being a probe tip. The first electrode (31) extends to the probe tip. The first electrode (31) is a hollow outer electrode and the second electrode (32) is an inner electrode extending at least along a section of the first electrode (31) inside the first electrode (31). The second electrode (32) except for a portion at its end is surrounded by a dielectric material (33). The probe (50) is adapted to be inserted into a root canal (3). The plasma jet device (30) is adapted to provide negative pulses at the second electrode (32) for producing the atmospheric pressure plasma at the tip of the second electrode (32). The invention further refers to a method for generating atmospheric pressure plasma.

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.
