DIN EN 61205:1995-02

Ultrasonic dental descalers are widely used for removing plaque and colculus from teeth. Although the mode of action of these devices has not been well characterized, the cleaning efficiency of ultrasonic dental descalers depends on the vibration amplitude. The purpose of this document is to define standard methods of measurement and specification of the essential vibration characteristics of ultrasonic dental descalers. Questions of safety and biological effects of the output are not treated in this document.
