Device Story
The miniMaster LED is an ultrasonic scaler used in dental clinics by professionals. It consists of a main chassis with an ultrasonic generator, bottle-fed irrigation system, and a handpiece with integrated LEDs for improved illumination of the treatment area. The device operates by delivering ultrasonic vibrations to specialized instruments attached to the handpiece, which are used for scaling, root planing, endodontic procedures, and restorative tasks. A 2-step footswitch controls water flow and ultrasonic tip movement. The clinician adjusts power settings and water flow via controls on the chassis and handpiece cord. The device provides visual feedback through the LED-illuminated handpiece, assisting the clinician in performing precise dental procedures. By facilitating efficient calculus removal and root canal preparation, the device aids in maintaining oral hygiene and performing restorative dental work.
Clinical Evidence
No clinical data. Substantial equivalence is supported by non-clinical bench testing, including electrical safety (UL 60601-1), electromagnetic compatibility (IEC 60601-1-2), packaging integrity (ISTA 2A), and validation of steam sterilization (ANSI/AAMI ST79 and ISO 17665-1).
Technological Characteristics
Ultrasonic scaler; 24V external power; 24-32 kHz frequency; 0-8W output. Materials: autoclavable plastic handpiece, stainless steel instruments, fluorocarbon rubber pump tubing. Features: bottle-fed irrigation (0-50 ml/min), 6-LED handpiece illumination, 10 discrete power settings. Sterilization: steam (moist heat) per ISO 17665-1. Connectivity: standalone.
Indications for Use
Indicated for dental and periodontal cleaning, preparatory, endodontic, and restorative procedures in patients requiring calculus removal, root planing, or dental restoration preparation.
Regulatory Classification
Identification
An ultrasonic scaler is a device intended for use during dental cleaning and periodontal (gum) therapy to remove calculus deposits from teeth by application of an ultrasonic vibrating scaler tip to the teeth.

## 5. DEVICE DESCRIPTION
The miniMaster LED is an ultrasonic scaler consisting of a main chassis containing an external electric power supply, controls and displays, ultrasonic generator, and a bottle-fed irrigation system. A 2-step footswitch is connected to the main chassis by a footswitch cord. A handpiece is connected to the main chassis by a handpiece cord, with irrigant flow control located on the cord itself. Instruments designed for specific dental procedures are attached to the distal end of the handpiece.
The miniMaster LED is a modification of the miniMaster Ultrasonic Scaler that was the subject of K050710. The overall design of the miniMaster LED is identical to the design of the miniMaster. The introduction of Piezon handpiece LED, materials changes to the peristaltic pump tubing, and design modifications implemented for the miniMaster LED were made to improve the functional performance and ease of use of the ultrasonic scaler. These design changes are listed in Table 1.
| Ultrasonic Scaler<br>. Component/Accessory<br>(Part Reference) | Design Modification |
|----------------------------------------------------------------|--------------------------------------------------------------------------------------------------------------------------------------------------------------|
| Piezon handpiece LED (EN-060/A) | Compatibility with Piezon handpiece LED which includes a light<br>guide and 6 LEDs placed under the nozzle to improve illumination of<br>the treatment area. |
| Handpiece LED cord (EM-113A/A) | Handpiece cords adapted to integrate LEDs |
| Cord connector (EK-300) | Cord connectors adapted to support LED |
| Water adjustment ring | Water adjustment ring relocated to handpiece side of handpiece cord |
| Electronics | Electronic PCB upgraded to drive the LED |
| Peristaltic Pump tubing* | Internal irrigation tubing replaced with fluorocarbon rubber material |
