Abstract
A device for scaling sordes and tartars on the surface of teeth at the gum pocket having improved construction, in which there are provided a hand-piece for an ejection nozzle; a compressor for feeding pressurized air to the ejection nozzle at one end of the hand-piece; a conduit pipe for transporting the compressed air; a water sump; and a conduit for leading water from the water sump to the ejection nozzle, the compressed air being ejected from the ejecting nozzle of the hand-piece under a pressure of from 1 to 2 kg/cm.sup.2 and in an ejecting quantity of from 6 to 9 l /min., and water being ejected together with the pressurized jet air in an ejecting quantity of from 10 to 30 cc/min. in the form of a spray jet.
Claims3
A device for scaling sordes and tartars on the surface of teeth at the gum pocket, which comprises:
- a hand-piece including an ejection nozzle;
- a compressor for feeding compressed air to said ejection nozzle at one end of said hand-piece;
- a conduit pipe for transporting the compressed air;
- a water sump;
- a conduit for leading water from said water sump to said ejection nozzle;
- said compressed air being ejected from said ejecting nozzle of the hand-piece under a pressure of from 1 to 2 kg/cm.sup.2 and in an ejecting quantity of from 6 to 9 1/min.;
- and
- venturi ejecting means for ejecting said water together with said compressed air in an ejecting quantity of from 10 to 30 cc/min. in the form of a pressurized air spray jet for exposing the surface of teeth at the gum pocket by separating the gingival from the teeth.
