More Information

Not Found

No
The document describes a standard dental X-ray system and does not mention any AI or ML capabilities.

No
The device is used for taking diagnostic dental X-rays, which falls under diagnostic imaging, not therapeutic treatment.

Yes
The "Intended Use / Indications for Use" section states that the device is "for taking diagnostic extraoral dental X-rays." This directly indicates its role in diagnosis.

No

The device description explicitly states it is a "battery-powered hand-held dental x-ray machine," indicating it is a hardware device that generates X-rays.

No, this device 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 ADX4000 Cordless Portable Dental X-ray System is a device that generates X-rays to create images of the teeth and surrounding structures. It does not analyze samples taken from the body.
  • Intended Use: The intended use clearly states it's for "taking diagnostic extraoral dental X-rays using intraoral digital sensors or film." This is an imaging procedure, not an in vitro test.

Therefore, based on the provided information, the ADX4000 is a medical imaging device, specifically a dental X-ray system, and not an IVD.

LEGALLY MARKETED PREDICATE DEVICE

For its indication for use, the DexcoWinA ADX4000 Cordless Portable Dental X-ray System is substantially equivalent to the Nomad Dental X-ray System cleared by FDA under K051795.

DEVICE DESCRIPTION

The DexcoWinA ADX4000 Cordless Portable Dental X-ray System is a battery-powered hand-held dental x-ray machine whose fixed output is 60 k Vo (Constant Potential). It can be used with either a digital sensor or conventional film. This is a prescription device that can be used on pediatric and adult patients.

SUBSTANTIAL EQUIVALENCE SUMMARY

A comparison of the Dexco WinA ADX4000 Cordless Portable Dental X-ray System and the Nomad™ Dental X-ray System is presented in Table 1.
