# Note for Detailed comparison

1. For the statement of intended use, even there is only minor difference on the words for indented use, but its meaning of the description So it has the same intended use as the predicate device (K090931).

2. There is difference of the weight between T-Fine-II and the predicate device. That is because the appearance of T-Fine-II is different from the predicate device, but the design of subject device comply with electrical safety standard IEC/AAMI 60601-1, so the minor difference would not affect its safety and Report by Foshan CICADA Dental Instrument Co, Ltd Page 17 of 50

### effectiveness.

.

3. The displayed parameters of T-Fine-Il are different from the predicated device, but the design of subject device comply with electrical safety standard IEC/AAMI 60601-1 and display function had been validated in software evaluation report, so the minor difference would not affect its safety and effectiveness.

4. There is minor difference on the battery capacity from 1050mAh, but the design of subject device comply with electrical safety standard IEC/AAM 60601-1, so the minor difference would not affect its safety and effectiveness.

5. There is minor difference on storage temperature and humidity of T-Fine-II, comparing with the predicate device, the device shall be stored according to the specified environment, so that it do not affect the function of the device. So the minor difference would not affect its safety and effectiveness.

6. Even there is minor difference on the torque setting range, however it is adjustable in the main unit by dentist operator, the device provide with auto reverse and stop function when motor bear the torque resistance higher than the setting torque: and the device comply with IEC80601-2-60 Requirement. So such minor difference would not affect its safety and effectiveness

# Conclusion

The subject device Endo motor has all features of the predicate device for intended use. Thus, the subject device is substantially equivalent to the predicate device.
