Device Description The E-connect S is a battery-driven handpiece with a motor, equipped with a chuck for holding rotary instruments such as a dental file. The E-connect S can be used for enlargement and preparation of root canals and can also be used as an apex locator. The motor drives the file to rotate at a certain speed and torque through the contra angle gearing. The rotating file will cut the root canal wall along the direction of the root canal. The speed and torque of the motor are controlled by the central processor and are configurable to accommodate different files. With built-in apex locator, this device monitors the file tip position in the root canal during root canal treatment. The components of the E-connect S include a charge base, handpiece, contra angle, insulating sleeve, file clip, lip hook, measuring wire, adapter, and spray nozzle. The contra angle is compatible with files shafts conforming to ISO 1971-1, Type 1. The key panel on the handpiece is used to control/adjust the power, memory settings, operation modes (motor/apex,) and adjust the parameters. The body of the handpiece is to be covered with a FDA cleared barrier sleeve. #### 7. Intended use & Indication for use E-connect S is a cordless endodontic treatment motorized handpiece with root canal measuring 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. This device must only be used in hospital environments, clinics or dental offices by qualified dental personnel. | Features | Subject Device | Predicate Device | Reference device | Comparison | |--------------------------------------------------------------|------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|--------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|------------------| | | E-connect S | K170275 | K191276 | ison | | | | Tri Auto ZX2 | Dental Electrical<br>Motor iRoot Pro | | | Applicant | Changzhou Sifary<br>Medical Technology Co.,<br>Ltd. | J.

Comparison to the Predicate Device {5}------------------------------------------------ {6}------------------------------------------------ Justifications for differences between proposed device and the predicate device are shown as below: Different (1): Target population in the E-connect S is included in that of the predicate devices, thus, this difference has no influence on substantial equivalence. Different (2): The exterior design of the E-connect S compared to the Tri Auto ZX2 has slightly changed {7}------------------------------------------------ for design. However, the structures of both devices which include the contra angle that connects and rotates the files, the probe for measuring the root canal length, and the built-in root canal length measurement function are substantially equivalent. Moreover, the principle of controlling the rotation by measurement result, load value, setting etc. is also substantially equivalent. Different (3): The rotation speed of E-connect S is within the speed of the predicate device, thus substantially equivalent. Different (4): The principle of the root canal length measurement function of the E-connect S is the same as the predicate device. Different (5): The sterility validation was performed according to ISO 17665-1. Thus, this difference does not raise different questions of substantial equivalence. #### Performance Data 9. The following performance data were provided in support of the substantial equivalence determination. ### Biocompatibility testing The biocompatibility evaluation for E-connect S was conducted in accordance with the FDA Guidance for Industry and Food and Drug Administration Staff: Use of International Standard ISO 10993-1, "Biological evaluation of medical devices - Part 1: Evaluation and testing within a risk management process". The battery of testing included the following tests: - . Cytotoxicity (ISO 10993-5: 2009) - Sensitization (ISO 10993-10: 2010) . - Irritation (Oral mucosa) (ISO 10993-10: 2010) . The subject devices are considered surface contacting for a duration of not exceed 24 hours. ### Non-clinical data The E-connect S has been tested according to the following standards: - . IEC 60601-1-2005+CORR.1:2006+CORR.2:2007+A1:2012, Medical Electrical Equipment-Part 1: General requirements for basic safety and essential performance - IEC 60601-1-2:2014, Medical electrical equipment- Part 1-2: General requirements for basic . safety and essential performance- Collateral standard: Electromagnetic compatibility-Requirements and tests - IEC 80601-2-60: 2012 Medical Electrical Equipment Part 2-60: Particular Requirements for .

Document for Reprocessing Medical Devices in Healthcare Setting. - Comparative Root Canal Measurement Performance Test to evaluate the root canal length . {8}------------------------------------------------ measurement accuracy to the predicate device. The test was selected to show substantial equivalence between the subject device and the predicate. ### Clinical data There were no clinical tests performed for the E-connect S device. ## 10. Conclusion Performance testing and compliance with voluntary standards demonstrate that the proposed subject device is substantially equivalent to the predicate device.
