Ask an average dental professional about QLF and there is a reasonable chance that the name is unfamiliar. Ask a researcher working in caries, plaque or oral-care product research, and the answer may be very different.
QLF has been studied for decades and described in more than 400 scientific publications. Universities, research institutions and oral-care companies around the world have used the technology to visualise, measure and monitor changes in oral health.

So why is QLF still relatively unknown outside those circles?
The honest answer is simple.
We spent our money on the technology.

Where the investment went

Inspektor Research Systems was founded by scientists and technologists, not by marketers.
Over the years, our resources went into optical systems, calibration, imaging software, clinical studies, algorithms and devices. We worked with researchers, universities and dental professionals to improve what QLF could reveal and measure.
Whenever there was a choice between making the technology better or making it better known, we usually chose the technology.

Scientifically, that brought us a long way. Commercially, perhaps less so.

What QLF makes visible

QLF stands for Quantitative Light-Induced Fluorescence. The technology illuminates the teeth with blue-violet light. Natural tooth structure responds with green fluorescence, while bacterial metabolites associated with mature plaque can appear red or orange.
Changes in the fluorescence of tooth structure can also provide information about mineral loss. With suitable imaging and analysis software, these changes can be recorded, quantified and compared over time.

This makes QLF useful for applications such as:

• visualising and measuring mature dental plaque;
• monitoring demineralisation and remineralisation;
• supporting caries research;
• evaluating oral-care products;
• documenting changes over time;
• making clinical information easier to explain to patients.

QLF does not replace professional judgement or other diagnostic methods. It provides additional visual and measurable information.

More evidence than advertising

Scientific publications do not automatically create public awareness.
A technology can be widely studied and still remain unfamiliar to many of the people who could benefit from it. That is what happened with QLF.
We concentrated on evidence, development and reliability. We assumed that a strong technology would eventually speak for itself.

It did speak.
Mostly in scientific journals.

Time to make the invisible visible

Oral Qamera was created to bring the original QLF technology beyond research and into everyday preventive oral care.
For professionals, that means clearer visual information, better patient communication and the ability to monitor changes over time.

For consumers and families, it means making daily oral hygiene easier to see and understand.
Perhaps we should have invested more in telling the story earlier.

But if we had to make the same choice again, we would still begin with the technology.

Unknown does not mean unproven. Sometimes it simply means the money went somewhere else
