22、BSI 11-19993 Introduction Ultrasonic dental descalers are widely used for removing plaque and calculus 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 t
23、his International Standard 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 standard. 1 Scope This International Standard specifie
24、s: essential non-thermal output characteristics of ultrasonic dental descalers; methods of measurement of the output performance of ultrasonic dental descalers; characteristics to be declared by the manufacturers of ultrasonic dental descalers. 2 Normative reference The following normative reference
