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.

Apparatus and methods for treating root canals of teeth

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.
