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.

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： This invention is achieved to provide a water-flow ultrasonic oral-cavity cleaning device and a method for water-flow ultrasonic oral-cavity cleaning for surely and efficiently cleaning an oral cavity. In the water-flow ultrasonic oral-cavity cleaning device 1, cleaning liquid W1 from a cleaning-liquid supplying device 2 is supplied into a transducer case 21 through a supply port 26. Ultrasonic waves S1 are propagated into the cleaning liquid W1 from an ultrasonic transducer 22 mounted in a transducer mounting part 23 inside the transducer case 21. The water-flow of the cleaning liquid W1 is collected at the apical-part inside the transducer case 21, and then emitted from the issue 27 into the oral cavity, wherein power supply of 100W or less is supplied to the ultrasonic transducer 22 of 50mm or less in diameter to propagate the ultrasonic waves S1 of 100kHz or more to 3MHz or less in frequency into the cleaning liquid W1.
