## Intended Use

Ultrasonic Scaler is used to remove dental plaque from teeth and remove stains on teeth during dental cleaning.

## Device Story

Ultrasonic Scaler is a dental device used for plaque and stain removal. It consists of an electronic oscillation circuit that generates ultrasonic frequency electric pulse waves. These pulses are amplified and transmitted to a transducer, converting electrical energy into mechanical energy. This mechanical vibration is delivered to a working head (scaler tip) to crush calculus and loosen tartar. The device is intended for use by dental professionals during cleaning and periodontal therapy. The operator controls the device, and output is monitored via an external display driver circuit with LED indicators. The device aids in reducing tooth decay and cleaning gingival areas. Benefits include efficient removal of adherent plaque and food debris from teeth and gingival lines.

## Clinical Evidence

Bench testing only. No clinical data provided. Performance verified through electrical safety, EMC, and biocompatibility testing (ISO 10993-5, ISO 10993-10, ISO 10993-23). Compliance with IEC 60601-1, IEC 60601-1-2, IEC 60601-1-11, IEC 62471, and IEC 80601-2-60 confirmed.
