摘要： Various systems, method, and compositions for treating a tooth are disclosed herein. For example, an apparatus for treating a tooth is disclosed. The apparatus can include a chamber having an access port which places the chamber in fluid communication with a treatment region of the tooth when the chamber is coupled to tooth. A fluid motion generator can be coupled to the chamber. The fluid motion generator can be configured to direct fluid across the access port to generate fluid motion in the chamber. In various embodiments, fluid motion (e.g., vortices, swirl, etc.) can be induced at or near treatment regions of the tooth, such as a root canal or carious region.

摘要： The invention relates to an endodontic instrument (20) for drilling root canals in a tooth. Said instrument comprises a working area (21) arranged so as to form and/or shape and/or cut the inner wall of the root canal. To this end, it is provided with a plurality of flutes wound around a central axis in the form of a spiral, within a conical envelope (25) having a cross-section that becomes narrower from one end (23) to the other end (26) of the instrument. Said working area (21) is sub-divided into adjacent segments (S) wherein the flutes alternately have a straight section and a section that is twisted in the form of a spiral and are arranged in such a way that the edges thereof are located either on the conical envelope (25) or inside said envelope on the straight sections or on the twisted sections.
