    Abstract: The invention is a low-splash dental fluid distribution implement with the ability to evenly wear down tooth decay, diseased tissue, or undesired dentin in oral applications with live patients. The directed multi-beams of pressurized fluid are a combined plurality of individual beams paired in such a manner that the reflected fluid bursts are inwardly directed against each other. This canceling effect prevents damage to the oral tissues of the patient's mouth by curtailing outward bound bursts of fluid arising from the initial directed impact. Also, the outer edges of the strike zone receive a comparable force as that which hits the center.

    Abstract: The cleaning apparatus includes a source of gas under pressure (12) and a source of fluid (14), along with associated gas (26) and fluid (34) chambers, adapted for successive single uses. A user-operated metered valve (22) connects the gas reservoir to the gas chamber, while a liquid pump (30) and a one-way valve (32) connects the liquid reservoir to the liquid chamber. When gas is released from the gas reservoir, it expands rapidly from the valve into the gas chamber, resulting in pressure therein sufficient to open a one-way valve (38) connecting the gas chamber to the liquid chamber. The gas in the liquid chamber forces liquid therein through a liquid line (15) to a connecting point with a gas stream line (13) from the gas chamber. The interaction of the fluid with the gas stream results in a spray of liquid droplets (17) which are directed out of the gas stream line exit orifice (16) to the teeth for cleaning.

  • Publication number: 20130196286
    Abstract: An apparatus for the generation of metallic and metal oxide nanoparticles for use in the treatment of periodontal disease has a discharge chamber with a controlled flow of water, the water flowing through a plasma gap formed by electrodes, the electrodes having a pulsed voltage applied to create a plasma discharge, the pulse duration chosen to maximize the generation of nanoparticles from the electrodes which are in the range of 10 nm to 50 nm. The discharge chamber flow rate and pulse duration is controlled to maintain a particular temperature differential across the plasma gap to additionally optimize the nanoparticles population for the desired 10 nm to 20 nm size range having negative surface electric charge. The nanoparticles thereby formed may thereafter be applied to a subject in need thereof as an irrigation treatment, or as a paste applied directly to a region of periodontal disease.

  • Patent number: 8454360
    Abstract: The interproximal cleaning apparatus includes a gas reservoir (12) containing a compressed gas, such as CO2, in both liquid and gaseous states. A siphon tube (20) extends down into the liquid region of the gas reservoir when the apparatus is in an upright position. The siphon tube connects the reservoir to a metering valve (18) which has a metered volume to accommodate an amount of liquid compressed gas which is sufficient for good liquid droplet cleaning when it decompresses and forms a gaseous stream, without damage to the dental regions of the user. If the apparatus is severely tilted or turned upside down, gaseous CO2 or a combination of gaseous and liquid CO2 will enter the siphon tube and then the metering valve. The size of the metering valve will limit the volume of the gaseous CO2 to a safe amount, both when liquid CO2 or gaseous CO2 are applied to the metering valve.

  • Patent number: 8382476
    Abstract: The invention relates to a dental composition comprising a hardenable powder to be used in a process for retraction of dental tissue. The invention also relates to a kit of parts comprising the dental composition comprising a hardenable powder, a hardening agent, optionally a handpiece of a powder jet device, optionally a powder jet device, and optionally retraction caps. In a further aspect, the invention relates to a method for retracting dental tissue comprising the steps of applying a dental composition comprising a hardenable powder with a powder jet device into the sulcus between soft and hard dental tissue, applying a composition comprising a hardening agent either before or after the previous step, leaving the dental composition in the sulcus for a time sufficient to effect retraction of the soft dental tissue and removing the dental composition from the sulcus.

  • Publication number: 20120003601
    Abstract: A tooth treatment device includes a detector that detects a marker of oral health and a fluid ejector that ejects fluid against teeth in response to the detected marker. The device can include a housing configured to be held on hand, the fluid ejector being positioned at an end of the housing. The fluid may include a liquid, a medicant, a cleansing solution, cleaning particles, or any combination thereof. The medicant can include any combination of a chelating agent, fluoride, a fluorescent dye, a bacterial specific probe, and a biochemical specific biomarker. Further, the device can include a servo controller controlling pressure of ejected fluid in response to the detected marker and a sensed surface condition, latter including for example, a mechanical property of tissue. The device may include a pressure sensor that senses pressure of the fluid in the ejector. Also included may be a distance sensor that senses distance of the ejector from a tissue surface.

  • Publication number: 20110223555
    Abstract: A jet device for use in dentistry has a tool holder providing an abrasive working fluid jet and a spray jet. The working fluid jet contains sharp-edged small abrasive particles suspended in a fast carrier air flow. The spray jet has small water droplets. The working material jet and the spray jet are emitted by spatially separated delivery nozzles. The spray jet thus does not reach to the working jet delivery nozzle.

  • Publication number: 20110207077
    Abstract: The cleaning apparatus includes a source of gas under pressure (12) and a source of fluid (14), along with associated gas (26) and fluid (34) chambers, adapted for successive single uses. A user-operated metered valve (22) connects the gas reservoir to the gas chamber, while a liquid pump (30) and a one-way valve (32) connects the liquid reservoir to the liquid chamber. When gas is released from the gas reservoir, it expands rapidly from the valve into the gas chamber, resulting in pressure therein sufficient to open a one-way valve (34) connecting the gas chamber to the liquid chamber. The gas in the liquid chamber forces liquid therein through a liquid line (15) to a connecting point with a gas stream line (13) from the gas chamber. The interaction of the fluid with the gas stream results in a spray of liquid droplets (17) which are directed out of the gas stream line exit orifice (16) to the teeth for cleaning.

  • Patent number: 7993135
    Abstract: A dental apparatus provides a substantially uniform concentration of abrasive material entrained in a pressurized gas to a desired location substantially irrespective the amount of abrasive material in a pressurized container of the apparatus, and resists clogging by the abrasive material. The apparatus includes a control unit having a container that secures the abrasive material, the abrasive material in the container becoming entrained in pressurized gas received from a dental unit. The concentration of the mixture of entrained abrasive material in pressurized gas is maintained by upwardly directing the flow of the mixture in a first conduit against a cap, a portion of the entrained abrasive material returning to the container, with the regulated mixture of entrained abrasive material in pressurized gas being delivered through a hand piece to the desired location.
