Abstract: 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 born 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.

Abstract: A water jet spray nozzle has a flow path including, from the upstream side to the end of the flow path, a small-diameter portion having a small inside diameter, an expanded portion having a larger inside diameter than the small-diameter portion, and a jet orifice having a smaller inside diameter than the expanded portion. The water jet spray nozzle is configured such that water passing through the flow path with a pressure of 0.2 to 0.6 MPa is retained in the expanded portion to as to generate cavitation bubbles from the small-diameter portion to the expanded portion. The inside diameter of the small-diameter portion § is 0.5 to 0.7 mm while the inside diameter of the jet orifice is 1 to 1.3 times larger than that of the small-diameter portion.
