Abstract
An apparatus for endodontic treatment, comprising: a nozzle connected to a fluid source comprising: a tip small enough to be inserted into a pulp chamber of a tooth; an inner geometry which forms a flow parameters including non-axial flow direction of nozzle fluid flowing through the inner geometry such that discharge fluid discharged from the inner geometry increase rotation of root canal fluid within a root canal sufficiently to remove tissue from the root canal.
Claims82
An apparatus for endodontic treatment comprising:
- a nozzle comprising:
- a tip sized and shaped to be inserted into a pulp chamber of a tooth and comprising an exit aperture;
- a lumen fluidly connected to said exit aperture;
- a first channel extending away from the lumen terminating at a first outlet inside said lumen;
- a second channel extending away from the lumen terminating at a second outlet terminating inside said lumen;
- wherein said lumen is configured and said first and said second outlets are positioned such that material exiting said first outlet and material exiting said second outlet mix within said lumen, exiting said nozzle through said exit aperture as a beam which:
- includes at least one fluid jet at an angle to a vertical axis of said nozzle;
- or which broadens as a distance between the beam and said exit aperture increases.

A method of endodontic treatment comprising:
- positioning a tip of a nozzle above an entrance to a root canal;
- discharging a first flow of material into a lumen of said nozzle through a first channel extending away from the lumen and a second flow of material into said lumen of said nozzle through a second channel extending away from the lumen allowing said flows to mix within said lumen to form a beam of material exiting said lumen through an exit aperture, where said beam has a shape which:
- includes at least one fluid jet at an angle to a vertical axis of said nozzle;
- or broadens as a distance between the beam and said exit aperture increases.

An apparatus for endodontic treatment comprising:
- a nozzle comprising:
- a tip sized and shaped to be inserted into a pulp chamber of a tooth and comprising an exit aperture;
- a lumen fluidly connected to said exit aperture;
- a first channel extending away from the lumen;
- a second channel extending away from the lumen which merges with said first channel to form a third channel, material from said first channel merging with material from said second channel;
- an outlet in said third channel inside said lumen;
- wherein said lumen and channels are configured and said outlet is positioned such that material exiting said nozzle through a nozzle exit aperture as a beam which:
- includes at least one fluid jet at an angle to a vertical axis of said nozzle;
- or which broadens as a distance between the beam and said exit aperture increases.
