Intended Use

The Dental Electrical Motor iRoot Pro is a cordless endodontic treatment motorized handpiece with root canal measurement capability. It can be used to enlarge canals while monitoring the position of the file tip inside the canal. It can be used as a low-speed motorized handpiece and device for measuring canal length.

Device Story

Cordless endodontic motorized handpiece; integrates apex locator for root canal length measurement. Input: electrical signals via file/lip clip circuit to determine apex position. Operation: electric motor drives rotary file; software controls speed, torque, and rotation modes. Output: LCD display of parameters (speed, torque, apex position); audible warnings. Used in dental clinics by dental professionals. Benefits: enables simultaneous canal enlargement and real-time monitoring of file tip position; improves procedural efficiency and safety. Four operational modes: motor-only; apex locator-only; independent motor/apex locator; and automated motor control (rotate/stop/reverse) based on apex locator feedback.

Clinical Evidence

No clinical data. Bench testing only. Verification included electrical safety (IEC 60601-1), EMC (IEC 60601-1-2), dental handpiece performance (ISO 14457, ISO 80601-2-60), biocompatibility (ISO 10993-5, -10), and apex locator accuracy testing.

Technological Characteristics

Cordless, battery-powered (Li-ion 3.7V) handpiece. Materials: 304 stainless steel, silica rubber. Connectivity: USB for charging. Sterilization: Autoclavable contra-angle and lip clip; barrier sleeves for central unit. Software: Moderate level of concern. Sensing: Dual-frequency impedance-based apex location.

Indications for Use

Indicated for endodontic treatment, specifically for root canal preparation (enlarging canals) and root canal length measurement in dental patients.

Regulatory Classification

Identification
