Indications for 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 Story
Apex Dental Sensors are intra-oral digital x-ray detectors used by dental professionals (radiologists, dental assistants) to acquire radiographic images. The device consists of a Cesium Iodide (CsI) scintillator that converts incident x-rays into visible light, which is then optically coupled to a CMOS-based light detection imager. The sensor automatically detects incident x-rays to generate data, which is transmitted via USB 2.0 to a PC. The device acts as a receiver only and does not control the x-ray generator. Software (Apteryx XrayVision) interprets the data to produce images for clinical review. The device assists in the diagnosis of dental, jaw, and oral diseases by providing high-resolution radiographic images, facilitating accurate clinical decision-making.
Clinical Evidence
Bench testing only. The device was tested for compliance with electrical safety (AAMI ES 60601-1:2005/(R) 2012), electromagnetic compatibility (IEC 60601-1-2:2007), performance (IEC 6220-1:2003), and dental intra-oral X-ray equipment safety (IEC 60601-2-65:2012). No clinical data was required or provided.
Technological Characteristics
Intraoral digital x-ray sensor using CMOS technology, fiber optic plate, and Cesium Iodide (CsI) scintillator. Available in two sizes (Size #1 S11684-12, Size #2 S11685-12). Pixel size 20x20μm.

### 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
{4}------------------------------------------------
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.
