However, this procedure will not remove all organic material from all canal spaces.
The action of the file during the process of opening the canal creates a smear layer of dentinal filings and diseased organic material on the dentinal walls, which is extremely difficult to remove.
The organic material and necrotic tissue that remain in the canal spaces after completion of the procedure often result in post-procedure complications such as infections.

Embodiment Construction
[0031]The present disclosure provides various apparatus and methods for dental treatments that overcome possible disadvantages associated with conventional root canal treatments. In certain embodiments, endodontic treatment methods (e.g., root canal therapy) comprise directing a high-velocity liquid jet toward a tooth. Impact of the jet causes acoustic energy to propagate from a site of impact through the entire tooth, including the root canal system of the tooth. The acoustic energy is effective at detaching substantially all organic material in the root canal system from surrounding dentinal walls. In many embodiments, the detached organic material can be flushed from the root canal using low-velocity irrigation fluid. As used herein organic material (or organic matter) includes organic substances typically found in healthy or diseased root canal systems such as, for example, soft tissue, pulp, blood vessels, nerves, connective tissue, cellular matter, pus, and microorganisms, whe...

Abstract
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.
