It is targeted for use by dental professionals (licensed clinicians) for enhanced diagnostic imaging in oral health care.
Regulatory Status & Market Use
-
Qraypen is an FDA-cleared product (via 510(k) clearance) as a dental intraoral camera.
-
In Korea, Qraypen C is classified as a Class II optical medical device (second-class) and designed for clinical diagnosis of dental caries, especially for individual teeth and proximal surfaces.
-
The device is suited for imaging both conventional (white-light) and fluorescence (Qray) images simultaneously.
Key Features & Capabilities
-
Dual-mode Imaging: It can capture both standard white-light images and specialized fluorescence (Qray) imaging, helpful for detecting caries, plaque, cracks, and other subtle defects that regular imaging might miss.
-
Auto focus System: The device includes an autofocus mechanism to simplify focusing in the intraoral environment.
-
Integrated LED Lighting: It features built-in LEDs (white and UV/blue) whose modes and brightness settings are adjustable.
-
Compact Form Factor & Compatibility: Designed as a hand-held device with a USB connection (USB 2.0) to connect to a PC or imaging software.AIOBIO | BLISS Store+2
-
Clinical Use & Research Backing: The product documentation mentions that more than 250 publications utilize its fluorescence imaging technology.
-
Ease of Operation: The site describes a user workflow: set up via USB, launch imaging software, choose LED mode, position on the tooth, capture the image—all with relatively simple controls.
