The biocompatibility test has been conducted on the K172543 and the test result comply with the requirements of ISO 10993. Therefore, the different will not affect the safety and effectiveness of the proposed device

## Different- Fiber optics

The fiber optics of the proposed device are different from the predicate device or reference device. The proposed device contains handpieces with and without lighting function. However, the predicate device is handpieces with light and the reference device is handpieces without light. Therefore, the fiber optics (with/without light) will not affect the safety and effectiveness of the proposed device.

#### Different- Light intensity

The light intensity of the proposed device is different from the predicate device. However, the light intensity of the proposed device meet the requirement of ISO 14457. And the proposed device shall be operated by trained healthcare professions. Therefore, the different will not affect the safety and effectiveness of the proposed device. Therefore, the different will not affect the safety and effectiveness of the proposed device.

## Different- Speed in rpms

The speeds of the proposed device are different from the predicate device. The 480,000rpm are out range of the predicate device. The different speeds will be selected by physician per patients' condition.

{8}------------------------------------------------

In addition, the performance test has been conducted on proposed device according to ISO 14457 and the test results meet the acceptable criteria. Therefore, the different will not affect the safety and effectiveness of the proposed device.

## Different- Head diameter

The head diameter of the proposed device is different from the predicate device. The 11mm and 9.5mm are out range of the predicate device. However, the difference is just in physical specification and different specification will be selected by physician per patients' condition. Therefore, the different will not affect the safety and effectiveness of the proposed device.

## Different- Sterilization

The steam sterilization method of the proposed device are different with the predicate device. However, the sterilization parameters comply with ISO 17665 standard. Therefore, the difference will not affect the safety and effectiveness of the proposed device.

## Different- Biocompatibility

The patient-contact materials of the Highspeed Airturbine Handpiece are identical device to that of the legally marketed device, High-speed Turbine Handpieces for Single Use, as cleared in K172543, which is also manufactured by Beijing Dongbo Dental Handpiece Co., Ltd. Therefore, the biocompatibility for proposed device is demonstrated by reference device (K172543). The biocompatibility testing for K172543 was evaluated and the tests results complied with ISO 10993 standards. Therefore, the patient-contact materials of the proposed device will not have the adverse effects on patients. Therefore, this difference does not affect the safety and effectiveness of the proposed device.

#### 9. Substantially Equivalent (SE) Conclusion

Based on the comparison and analysis above, the proposed devices are determined to be Substantially Equivalent (SE) to the predicate devices.
