No
The summary describes a standard electronic apex locator and does not mention any AI or ML capabilities.

No.
The device is used for measurement and diagnostic purposes, not for treating a disease or condition.

Yes
The device is intended for the measurement of the length of the root canal, which is a form of anatomical measurement used to aid in diagnosis and treatment planning in dentistry.

No

The device description explicitly states it is a "dental medical device which has the ability to measure the depth of the root canal by electronic means." This implies the presence of hardware components for electronic measurement, not just software.

Based on the provided information, the NSK Precision Apex Locator is not an IVD (In Vitro Diagnostic).

Here's why:

  • IVD Definition: In vitro diagnostics are tests performed on samples taken from the human body, such as blood, urine, or tissue, to detect diseases, conditions, or infections.
  • Device Function: The NSK Precision Apex Locator measures the length of the root canal within the patient's body using electronic means. It does not analyze samples taken from the body.
  • Intended Use: The intended use is for measuring root canal length during dental procedures, not for diagnostic testing of biological samples.

Therefore, the NSK Precision Apex Locator is a medical device used in vivo (within the living body) for a procedural purpose, not an in vitro diagnostic device.

Characteristics: | With respect to technology and intended use, the NSK Precision Apex
Locator is substantially equivalent to its predicate device which is the
MedicNRG Electronic Apex Locator. The primary difference is that the NSK
device utilizes a LCD display whereas the NRG device utilizes a LED
display. Based upon testing results, NSK believes this difference does not
raise additional safety of efficacy concerns. |

Dear Mr. Hattub:

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 mav, therefore, market the device, subject to the general controls provisions of the Act. 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.

If your device is classified (see above) into either class II (Special Controls) or class III (PMA), it may be subject to such 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 docs 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 801); good manufacturing practice requirements as set forth in the quality systems (OS) regulation (21 CFR Part 820); and if applicable, the electronic product radiation control provisions (Sections 531-542 of the Act); 21 CFR 1000-1050.

This letter will allow you to begin marketing your device as described in your Section 510(k) premarket notification. The FDA finding of substantial equivalence of your device to a legally marketed predicate device results in a classification for your device and thus, permits your device to proceed to the market.

If you desire specific advice for your device on our labeling regulation (21 CFR Part 801), please contact the Office of Compliance at (240) 276-0115. Also, please note the regulation entitled.
