Young boy is checking Colgate OQ with oral qamera

A year ago Inspektor Research Systems started to introduce a new brand. A brand for serving the clinical and consumer markets. In this year a lot happened. We have set steps in the right direction but we have not yet reached our goal: waking up in a world without caries. Cariogenic dental plaque causes the number 1 disease in our country and elsewhere. Dental plaque does not only cause substantial damage to people’s teeth, but also takes a big cut in the available care budget. Dental caries is associated with the development of cardiovascular and Alzheimer’s diseases. We could save some 52 billion Euro annually on our healthcare costs by taking effective prevention steps.

Waking up in a caries free world.

We all want this, you might think. That is both true and untrue: although being a desired outcome by the vast majority, in day-to-day real life politicians and health insurers are still focused on curing people rather than preventing people from getting sick. And most healthcare professionals have been educated to cure diseases. Therefore, the focus of dentistry is still on filling cavities, rather than preventing cavities from developing.

Fortunately, we get support from an unexpected angle.

At the moment a number of dentists is working with Oral Qamera and more will start using this technology in the near future. We will keep you posted on which practices are joining. Right now a leading dental equipment manufacturer has decided to integrate our QLF technology into their equipment. And then there is a sudden support from an unexpected angle. Colgate introduces Oral Quotient. “Do You Know Your OQ™?” links to their website. By the way: if you want to know more about our devices, please send us an email.

Detecting young plaque with Oral Qamera.

It is only a matter of time before you can detect young dental plaque with Oral Qamera. This means that, at the end of the day, you can see whether you have brushed properly in the morning. This new Oral Qamera device works with an app to help you keeping track of your oral hygiene on a daily basis. Never fear the dentist again is just a matter of time. With this initiative from Colgate, we are one step closer.

Ask an average Dutch dentist what QLF technology is and the answer will elude him or her. When one asks the same question to a researcher form a renowned university in the field of dentistry somewhere around the world, then he will answer that QLF is seen as the golden standard in research and scientific communities. QLF has been described in over 400 scientific articles. Publications have appeared in leading journals such as the Journal of Dentistry, Caries Research, Operative Dentistry and Oral and Craniofacial Research. But also in The Journal of Evidence-Based Dental Practice and American Journal of Orthodontics and Dentofacial Orthopaedics.


QLF™ uses fluorescence. Fluorescence is a property of specific substances, fluorophores, that absorb light of a specific colour (wavelength) and emit light in a different colour (of a different wavelength). By blocking the light of the original colour with a filter, the fluorescent image remains. The image is created by the light that the fluorophores emit. QLF™ uses two types of fluorophores. Porphyrins that are produced by bacteria that fluoresce red, and fluorophores that are on the border of tooth enamel and dentin that fluoresce green. The red fluorescence is a measure of harmful bacterial activity and the green fluorescence shows minor damage to the tooth enamel. Combined with the special filter, this produces the QLF image. In the QLF image, the contrast between clean and infected tissue and between healthy and damaged enamel is much greater than with normal illumination. This also makes it much easier for laymen to see whether a mouth is healthy or not. Another advantage is that the degree of contamination and the extent of the damage to the enamel can be measured at any time. In turn these measurements can be utilised to create an objective view of the development of oral health over time. Because the method is very sensitive and shows even the slightest deviation, action can be taken before it is too late.
