PURPOSE: An ultrasonic scaler tip is provided to maintain a scaling function to a specified level regardless of the abrasion of the end of the scaler tip. CONSTITUTION: An ultrasonic scaler tip comprises a body part(310), and an end part(320) which is formed in the front end of the body part. Multiple grooves(311) are formed in the end part so that a protrusion can be formed. The protrusion is formed vertically and maximizes vibration efficiency of ultrasonic waves in the edge portion. The grooves maintain tartar removal efficiency. |
