摘要： Provided is a dental ultrasonic cleaning device that efficiently cleans teeth or dentures in an oral cavity using ultrasonic waves. A dental ultrasonic cleaning device 1 emits ultrasonic waves through a cleaning-liquid (W1) to the surface of a cleaning-target 26, ultrasonically cleaning it. An ultrasonic horn 24 propagates ultrasonic waves being generated by an ultrasonic-wave transducer 23 and emits them from the vibratory surface 25 provided at the tip-end of the horn 24. A liquid-reserving part 27 is provided, surrounding the vibratory surface 25 of the ultrasonic horn 24, which temporarily reserves the cleaning-liquid (W1) between the vibratory surface 25 and the cleaning-target 26. A cap-member 33 is provided at a certain interval opposite the liquid-reserving part 27. A cleaning-liquid discharge-tube inlet 35 is connected to a vacuum tube 36 within the cap-member 33, allowing the cleaning-liquid W1 used during the ultrasonic cleaning to be vacuumed from the oral cavity, into the cap-member 33, and then discharged through the vacuum tube 36.

摘要： Provided is a device for cleaning oral cavity and a method for cleaning oral cavity capable of well cleaning stains such as plaque, tartar, and the like even in a narrow portion such as a clearance between teeth, a clearance between implants, and the like. A cover 11 includes a jetting orifice 11a and a discharge orifice 11b and covers a tooth 1 by leaving a clearance between the tooth 1 and the cover 11 so that the clearance can hold water. A jetting unit 12 is mounted in the jetting orifice 11a and includes a flow path 24a communicating with the clearance between the tooth 1 and the cover 11. The jetting unit 12 is configured to generate cavitation bubbles by water flowing toward the clearance in the flow path 24a and jets the cavitation bubbles toward the inside of the cover 11. The flow path 24a includes a small diameter part 24b having a flow path diameter smaller than that on the upstream side and an enlarged part 24c having a flow path diameter larger than that of the small diameter part 24b. A discharge unit 13 discharges water in the clearance between the tooth 1 and the cover 11 from the discharge orifice 11b.
