APEX LOCATOR is a device intended for locating the apex of the root canal during endodontic treatments.
Device Description
APEX LOCATOR is a device used in dentistry to estimate the position of the root apex of teeth during root canal preparation. It is used connected with the Cefla dental units. Its principle of operation relies on measuring the electrical impedance of dental tissue, which varies according to tissue density and composition. The APEX LOCATOR is an accessory device for the Cefla dental units used to estimate the position of the root apex of teeth during root canal preparation. The kit is composed of the following elements: file clip (2 pieces), lip hook (4 piece), external wiring (1 piece).

Not Found

No
The description focuses on electrical impedance measurement and does not mention AI/ML terms or related concepts like training/test sets.

No
The device is used for locating the apex of the root canal, which is a diagnostic or measurement function and does not directly treat a disease or condition.

No

The device is described as an "APEX LOCATOR" which is intended for "locating the apex of the root canal" and to "estimate the position of the root apex of teeth during root canal preparation." While it provides information that aids in a procedure, its primary function is to provide positional estimation rather than to diagnose a medical condition or disease. It uses electrical impedance measurements to locate a anatomical landmark, not to assess health status or presence of pathology. Its purpose is to guide a treatment, not to diagnose a condition.

No

The device description explicitly lists hardware components (file clip, lip hook, external wiring) and describes its operation based on measuring electrical impedance, which requires hardware. Performance testing also includes electrical safety and electromagnetic compatibility, further indicating a hardware component.

Based on the provided information, this device is not an IVD (In Vitro Diagnostic).

Here's why:

  • IVD Definition: In Vitro Diagnostic devices are used to examine specimens derived from the human body (like blood, urine, tissue) outside of the body to provide information for diagnosis, monitoring, or screening.
  • Device Function: The APEX LOCATOR works by measuring electrical impedance within the root canal of a tooth in situ (inside the patient's mouth). It is used during a dental procedure on a living patient.
  • Intended Use: The intended use is to locate the apex of the root canal during endodontic treatments, which is a procedural aid, not a diagnostic test performed on a specimen.

Therefore, the APEX LOCATOR falls under the category of a medical device used for a procedure on a patient, not an in vitro diagnostic device.

Dear Daidone Simona:

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 (the 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 available 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.

Additional information about changes that may require a new premarket notification are provided in the FDA guidance documents entitled "Deciding When to Submit a 510(k) for a Change to an Existing Device" (https://www.fda.gov/media/99812/download) and "Deciding When to Submit a 510(k) for a Software Change to an Existing Device" (https://www.fda.gov/media/99785/download).
