    摘要: An appliance and corresponding method for delivering antimicrobial agents to the vicinity of dental biofilm and for killing bacteria therein includes a system (18, 20, 24) for delivering polymeric capsules containing gas bubbles and an antimicrobial agent. A source of ultrasonic energy (18) is provided for moving the capsules toward the biofilm, the ultrasonic energy having sufficient intensity for thereafter bursting the capsules, in the vicinity of the biofilm, releasing the gas bubbles and the agent. The gas bubbles vibrate within the ultrasound field, disrupting the biofilm, so that the released agent can act effectively against the bacteria in the disrupted biofilm.

    摘要: The interdental cleaner includes a source of liquid (22) and a control system (42) including a manual pump (26), for moving a selected amount of liquid, suitable for a single use, into a liquid pathway and there to a mixing chamber (53). A source of pressurized gas (30), such as a CO2 cartridge, is used to preload a selected amount of gas into a gas chamber (52). The control system includes a spring-loaded button (18), which upon operation results in the manual pump (26) being operated, forcing the selected amount of liquid into the mixing chamber, and then upon release, permits the pressurized gas in the gas chamber to enter the mixing chamber, breaking up the liquid therein into droplets and a liquid stream, and propelling the resulting liquid out of a nozzle portion (14) of the cleaner into the interproximal area of the teeth.

    摘要: The apparatus includes a source of gas (air) bubbles (14) in a liquid medium, the gas bubbles having a size range which is associated with the size of bacteria alone or in colonies, on teeth or other surfaces. A source of ultrasound signals (16, 18) has a range of frequencies between 200 kHz and 2 MHz, the ultrasound frequency range including the resonance frequencies of a majority of the bubbles. The application of the ultrasound to the bubble/liquid stream directed toward the biofilm on the teeth results in a dislodging/removal of the biofilm.

    摘要: The interproximal cleaning appliance includes a housing (12) and a spray applicator (16) extending therefrom for directing a spray of fluid droplets to the interproximal area. Within the housing is a spray-generating assembly (14) which includes a chamber, a movable piston (26) mounted therein, one-way inlets (42, 40) for gas and fluid and an outlet (44). A system (54) for moving the piston, such as a motor, operatively compresses a spring (32) which creates a partial vacuum in the chamber, allowing gas to flow into the chamber through the gas inlet. Release of the spring produces a stream of fluid droplets which flows out of the chamber through the applicator to the interproximal area.
