Intended Use
The Apex Dental Sensors is intended to be used for a radiographic examination by a dental professional to assist in the diagnosing of diseases of the teeth, jaw and oral structures.
Device Description
The Apex Dental Sensors is an electronic medical device used to acquire intra-oral radiographic images. The sensor can be operated by Radiologists, Dental Assistants and other healthcare professionals, who are both trained and competent to take Dental X-ray radiographs. Intra-oral positioning of the sensor is accomplished by the use of dedicated intra-oral positioning devices that facilitate the accurate alignment of the x-ray beam. The sensor may also be aligned with the assistance of the patient. The Apex Dental Sensors is an indirect light converting digital x-ray detector. A scintillating device composed of Cesium Iodide (Csl) converts incident x-rays into visible light that is optically coupled to a light detection imager based on CMOS technology. The Apex Dental Sensors allow for automatic detection of such incident x-rays in order to generate data. Software interprets this data into images used for dental applications. The Apex Dental Sensors support USB 2.0 direct connectivity to personal computers and or laptops with dedicated electronics and a sensor software driver. The subject device does not control the generator, it is only a receiver. The X-ray system and the software used are not a part of this submission.
More Information

No
The description focuses on the hardware (sensor technology) and basic software for image interpretation. There is no mention of AI, ML, or advanced image processing techniques that would suggest the use of these technologies. The performance studies listed are standard electrical, safety, and imaging performance tests, not studies related to AI/ML algorithm validation.

No
Explanation: The device is an x-ray sensor used for acquiring images to assist in diagnosis, not for treating diseases or improving health outcomes.

Yes
The 'Intended Use / Indications for Use' explicitly states that the device is intended "to assist in the diagnosing of diseases of the teeth, jaw and oral structures."

No

The device description explicitly states it is an "electronic medical device" and describes hardware components like a sensor, scintillating device, CMOS technology, and USB connectivity. While software is mentioned for image interpretation, the core device is a physical sensor.

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

Here's why:

  • IVD Definition: In vitro diagnostic devices are used to examine specimens taken from the human body, such as blood, urine, or tissue, to provide information for the diagnosis, treatment, or prevention of disease.
  • Apex Dental Sensors Function: The Apex Dental Sensors is an imaging device that acquires radiographic images of the teeth, jaw, and oral structures using X-rays. It does not analyze biological specimens.
  • Intended Use: The intended use is for radiographic examination to assist in diagnosing diseases of the teeth, jaw, and oral structures, which is a function of medical imaging, not in vitro diagnostics.
  • Device Description: The description clearly outlines its function as an electronic medical device for acquiring intra-oral radiographic images using X-ray technology.

Therefore, the Apex Dental Sensors falls under the category of a medical imaging device, not an in vitro diagnostic device.

The types of x-ray systems that would integrate with the Apex Dental Sensors are wall-mounted x-ray generators (both AC and DC) with a tube current between 1 and 15 mA inclusive, and with a tube voltage between 50 and 100 kV inclusive, with in-built controls to set exposure parameters. Generators allow variable mA/kV to be selected, all will control the exposure time. The subject device is only a receiver, and not a controller. The subject device and the software cannot act as the controller of an x-ray generators are controlled by built-in controllers. The Apteryx Xray Vision software needs assistance from a TWAIN driver to recognise X-ray images.
