<p>PROBLEM TO BE SOLVED: To make the area with which a tooth comes into contact larger, and efficiently remove bacterial plaque and cul-de-sac by a method wherein for a scaling tip which removes tartar or cul-de-sac existing between a tooth and a gum, the tip end is bent based on the longitudinal direction, and also, the scaling tip is formed into an arc-form of which the tooth side is made a recessed surface side. SOLUTION: This scaling tip 10 is used in order to remove bacterial plaque and cul-de-sac 3 by inserting it between a tooth l and a gum 5, to improve a blood stream by applying a stimulation (an ultrasonic vibration) to the gum 5 in the vicinity of a root of tooth, and also, to perform a medical treatment for gum. For such reasons, when it is driven by an ultrasonic vibration, an ultrasonic oscillator is provided in a gripping part 20. Then, for this tip 10, the surface side of the tip end is bent based on the longitudinal direction so that it may become easier to come into contact with the tooth 1, and the tip 10 is formed into an arc-form of which the tooth 1 side is made a recessed surface side. Or, it is formed into a shape like a spoon of which the gum 5 side is expanded into a protruding shape. By this method, the area with which the tooth 1 comes into contact can be made larger, and bacterial plaque and the cul-de-sac 3 can be efficiently removed.</p> |
