The present invention provides a method for dental cutting including the steps of providing a dental unit water line irrigation system, the dental unit water line irrigation system including a container surrounding a solution chamber; providing a lubricant for use in the dental unit water line irrigation system, the lubricant defining a composition including 10 to 25% by weight of ethanol; 5 to 25% by weight of glycerol; 10 to 25% by weight of xylitol; 0.5 to 5% by weight of a nonionic surfactant and emulsifying agent; 0.15 to 0.5% by weight of a plurality of flavoring agents; and 45 to 60% by weight of water; and selectively operating the water line irrigation system to express the lubricant onto a dental cutting site.

A tip assembly for use with a dental tool, the tip assembly comprising a housing for attaching to the dental tool, at least one aspiration needle having a passageway extending at least partially through the aspiration needle, a substantial length of the aspiration needle, or at least from one end to the other end of the aspiration needle, the passageway providing a single continuous path to aspirate the irrigant and/or debris from the root canal cavity of the tooth, and at least one irrigation needle having a passageway extending at least partially through the irrigation needle, a substantial length of the irrigation needle, or at least from one end to the other end of the irrigation needle, the passageway provides a continuous flow path for delivering fluid/irrigant from a reservoir in communication with a proximal end of the irrigation needle to the distal end of the irrigation needle and into a root canal/coronal opening of a tooth.

Disclosed are methods for performing endoscopy comprising directing a distal end of an endoscope to proximity of a portion of a surface of a bodily cavity; and directing a liquid-gas stream at a portion of the surface of the bodily cavity. Disclosed are also devices useful in endoscopy, comprising: an elongated body having a proximal end and a distal end; a nozzle at the distal end; a gas channel configured for conveying a gas from the proximal end to the nozzle; and a liquid channel configured for conveying a liquid from the proximal end to the nozzle, wherein the nozzle is configured to generate a liquid-gas stream directed in a specified direction from a gas conveyed by the gas channel and a liquid conveyed by the liquid channel.

This present invention provides a delivery device that could be used to delivery discreet small volume of expensive biotechnology treatments to specific areas of the oral cavity, or other tissues. The present invention also provides a method of using the device disclosed herein to deliver biotechnology treatments and/or therapeutic agents to specific areas of the oral cavity, or other tissues. In one embodiment, the treatments and/or therapeutic agents are delivered to the interproximal area between and around the teeth.

A dental prosthesis has a gum sealing rim that snugly contacts the patient's gum. The cavity formed within the gum sealing rim is accessed by through holes via which a pressurized cleaning fluid may be injected into the cavity. The cleaning fluid swirls around and washes of bacteria and deposits. Through a number of cleaning fluid drains, the cleaning fluid exits again the cavity. An additional drain blocker may be configured such that it blocks the cleaning fluid drains while it is clamped by the patient between the teeth. The resulting pressure build up in the cavity causes the cleaning fluid to squeeze out and clean the sealing interface between the gum sealing rim and the patient's gum.

The present invention relates to a teeth washer structure, which includes: a guiding tube and an ejecting tube; the guiding tube includes a connection part, a tube body, an engage part and a first flow channel formed therein, a surface of the connection part is formed with a thread, and the portion of the first flow channel defined in the engage part is formed with a gradually-shrinking structure. One end of the ejecting tube is formed with a water inlet part connected to and communicated with the connection part in a watertight manner, another end thereof is disposed with an ejecting nozzle, the end of the ejecting tube where the ejecting nozzle is disposed is formed with a bendable structure, the interior of the ejecting tube is formed with a second flow channel mutually communicated with the first flow channel.

Hands-free systems, devices and methods, adapted for brushing, cleaning and treating all of a user's teeth simultaneously, are provided. In some embodiments, such a device comprises brushes for cleaning all of a user's teeth simultaneously. In some embodiments, such a device includes a generally U-shaped channel(s), accepting, cleaning and/or treating all of a user's teeth simultaneously. Customized fluid jets within such devices are provided, introducing dentifrices and other treatments into the channels. In some embodiments, compartments and cartridges with a proprietary form factor for delivering dentifrice and other treatments and for disposing of waste without mess are provided. In some embodiments, data are gathered, analyzed and serve as the basis for a treatment plan, which may then be carried out by the system(s), device(s) and method(s), over time.

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.

A dental syringe device that provides air and water to a dental patient. The device includes an adapter that connects a dental tip to a dental syringe body. The dental syringe body provides a conventional syringe body with a handle for a dentist to hold onto and a source of air and water. The tip delivers the air and water to the dental patient. The adapter is an improved adapter having a unique release and attachment component allowing for a quick connect and disconnect between the dental syringe body and the tip. The tip advantageously includes an inner portion with large and uniform air channels for smooth transfer of air and an outer portion made from a rigid plastic that provides an improved cheek retraction feature.

A device for drying a root canal includes a cannula configured to inject a gas stream into the root canal. The cannula is a conduit having a proximal end in fluidic communication with a distal end. A handpiece is configured to removably hold the proximal end of the cannula at a distal handpiece end. A gas stream source is connectable to a proximal end of a tube. A distal end of the tube is connectable to the proximal handpiece end. A cut-off valve is disposed within the handpiece in fluidic communication in series between the distal handpiece end and the proximal handpiece end. The cut-off valve is configured to cut off the gas stream flowing through the handpiece. A manually-controlled operating element is mechanically coupled to the cut-off valve, where the operating element is configured to be controlled by a dentist or technician holding the handpiece.
