Qraycam Pro
QLF™ Intraoral Camera
From screening to solution — simple, precise, rapid diagnosis. Qraycam Pro applies QLF™ (Quantitative Light-induced Fluorescence) technology to capture full-arch fluorescence images of caries, cracks, and plaque in a single chairside session. Backed by 250+ peer-reviewed publications and listed on the Australian Register of Therapeutic Goods (ARTG Included — Class IIa), Qraycam Pro elevates the standard of evidence-based preventive dental care.
What clinicians are saying
Real-world feedback from dental professionals using the Qraycam Pro in their practices.
"For implant planning and preventive recall, the 405nm fluorescence gives me information I simply didn't have before. I placed an implant in a site where the Qraycam had already flagged interproximal demineralisation on the adjacent tooth — caught at a stage where remineralisation was still viable. Without the QLF image, that finding would have waited until the next bitewing."
"The plaque fluorescence is what moves patients. I can explain oral hygiene ten ways and get a polite nod — but when they see the red fluorescence map of their own arch on the screen and connect it to where their gum line is inflamed, the conversation changes completely. It's the most effective patient communication tool I've added to the practice in years."
When to use Qraycam Pro
A high-tech screening device for dental clinics — designed to identify conditions that are difficult or impossible to detect with the naked eye or conventional X-ray imaging.
Designed for everyday clinical efficiency
Every aspect of Qraycam Pro — from the integrated LED system to the plug-and-play PC connection — is optimised for fast, reliable chairside imaging.
Imaging System
Integral LED lights — selectable with a single click
White and blue (405nm) LEDs are built directly into the device body and are switchable between modes with one click. The attached hood blocks ambient operatory light — allowing consistent fluorescence images regardless of chair lighting conditions, without needing a darkened room.
Display
Extended 3.5-inch LCD for immediate image review
An extended 3.5-inch HDMI LCD monitor is built into the device, allowing the operator to check image composition and quality immediately after capture — without returning to the workstation screen. Images are simultaneously auto-saved to the connected PC for records and patient consultation.
Software & Usability
LINKDENS software — capture, analyse, and chart in one workflow
Qraycam Pro works in conjunction with LINKDENS, AIOBIO's dedicated QLF™ capture and analysis software. Images are auto-saved to the connected PC on capture and can be reviewed immediately on the 3.5-inch LCD — then used directly in chairside consultations or exported to practice management software. The built-in driver installs automatically on USB connection; M12 liquid lens autofocus achieves a sharp image within 4 seconds, with no manual focus adjustment needed.

QLF™ fluorescence imaging in the clinical setting — full-arch screening with Qraycam Pro.
QLF™ imaging across five clinical scenarios
Fluorescence images captured with Qraycam Pro — white-light and QLF™ views displayed side by side for immediate clinical reference. Under the 405nm blue LED, carious demineralisation appears as a loss of green fluorescence; bacterial plaque fluoresces red via porphyrin emission. Both signatures are invisible under white light alone.
Case 01
Surface Caries
Demineralised enamel loses its natural green fluorescence under 405nm blue light, appearing as a dark zone against the bright healthy surface. Early-stage carious lesions not visible under white light are identified, enabling intervention before cavitation occurs.
Case 02
Caries Detection
Lesion extent and severity mapped under QLF™ imaging — providing a clear fluorescence picture of the affected area to guide clinical decision-making and support patient communication.
Case 03
Crack
Fracture lines invisible under white-light examination are highlighted by QLF™ fluorescence — supporting earlier diagnosis of cracked tooth syndrome and fracture risk assessment before irreversible structural damage occurs.
Case 04
Plaque
Bacteria in plaque emit a characteristic red fluorescence under 405nm blue light — driven by porphyrin compounds produced by oral microorganisms. Plaque distribution is made visible in real time across the arch, providing objective image evidence for patient education and hygiene monitoring.
Case 05
Prosthetic
Secondary caries and cracks in and around existing prosthetic restorations screened non-invasively — a diagnostic capability that conventional clinical examination and radiographs cannot consistently achieve.
