The summary describes a device that measures root canal apex position using electrical impedance, with no mention of AI or ML technologies in the description, intended use, or performance studies.
No
The device is used to detect the apex of the root canal, which is a diagnostic function for measurement, not a therapeutic intervention.
Yes
The device is used to "detect the apex of root canal" and performs "apex position measurement", which are diagnostic functions.
No
The device description explicitly states it includes a TFT colour display with touch panel and is described as "oral equipment," indicating it is a physical device with hardware components beyond just software.
Based on the provided information, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- Intended Use: The intended use is to "detect the apex of root canal." This is a measurement performed directly on the patient's anatomy (the root canal), not on a sample of biological material taken from the patient.
- Device Description: The device is described as "oral equipment used for root canal measurement." This further reinforces its use in a clinical setting directly on the patient.
- Lack of Biological Sample Analysis: There is no mention of the device analyzing blood, urine, tissue, or any other biological sample. IVD devices are specifically designed to perform tests on such samples to provide information about a patient's health status.
Therefore, the Root Apex Locator C-ROOT I is a medical device used for a clinical procedure, not an in vitro diagnostic device.

Dear Ray Wang:
We have reviewed your Section 510(k) premarket notification of intent to market the device referenced above and have determined the device is substantially equivalent (for the indications for use stated in the enclosure) to legally marketed predicate devices marketed in interstate commerce prior to May 28, 1976, the enactment date of the Medical Device Amendments, or to devices that have been reclassified in accordance with the provisions of the Federal Food, Drug, and Cosmetic Act (Act) that do not require approval of a premarket approval application (PMA). You may, therefore, market the device, subject to the general controls provisions of the Act. Although this letter refers to your product as a device, please be aware that some cleared products may instead be combination products. The 510(k) Premarket Notification Database located at https://www.accessdata.fda.gov/scripts/cdrh/cfdocs/cfpmn/pmn.cfm identifies combination product submissions. The general controls provisions of the Act include requirements for annual registration, listing of devices, good manufacturing practice, labeling, and prohibitions against misbranding and adulteration. Please note: CDRH does not evaluate information related to contract liability warranties. We remind you, however, that device labeling must be truthful and not misleading.
If your device is classified (see above) into either class II (Special Controls) or class III (PMA), it may be subject to additional controls. Existing major regulations affecting your device can be found in the Code of Federal Regulations, Title 21, Parts 800 to 898. In addition, FDA may publish further announcements concerning your device in the Federal Register.
Please be advised that FDA's issuance of a substantial equivalence determination does not mean that FDA has made a determination that your device complies with other requirements of the Act or any Federal statutes and regulations administered by other Federal agencies. You must comply with all the Act's requirements, including, but not limited to: registration and listing (21 CFR Part 807); labeling (21 CFR Part
1

Analysis:
Difference(1)
The proposed device includes the same main specifications as compared to the predicate device but differs in dimension, which is caused by different appearance design and could not effects the performance and safety.
Difference(2)
There is a difference in the cable length, but these cables include the same function , the cable length difference would not affect its safety and effectiveness.
Difference(3)
The proposed device and the predicate device have a different weight, however, this could not effect the performance and safety.
Difference(4)
Both the proposed device, the predicate device and the reference device are powered by rechargeable 3.7V Li-ion battery, there is a difference in the battery capacity. The proposed device compli es with
9
electrical safety standard IEC 60601-1, and its Li-ion battery complies with the battery standard IEC 62133-2, so the difference in battery capacity would not affect its safety and effectiveness.
Difference(5)
There is a difference on the description of adjustment before measurement, however both the proposed device and the predicate device have the same function, the proposed device does not specify the specific value of the adjustment range, but uses colors to identify the adjustment range, so such description difference would not affect its safety and effectiveness .
Difference(6)&(7)
Both the Patient contacting components materials of proposed device and predicate device meet the ISO10993-5 &ISO10993-10 standards, and the proposed device also meets the ISO10993-11 standard, the difference would not affect its safety and effectiveness.
Difference(8)
The material of root canal files that can be used with the predicate device and the reference device are unknown, however, a clinical accuracy study was conducted on the proposed device and root canal file of Nickel titanium (NiTi) material, the result meet the requirement of ±0.5mm measurement accuracy, so the difference would not affect its safety and effectiveness.
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.
