What’s black and white and ‘read’ all over?

Posted by Team DEXIS



The Centers for Disease Control (CDC) posted these interesting facts on caries1:  

Although dental caries (tooth decay) is largely preventable, it remains the most common chronic disease of children aged 6 to 11 years (25%), and adolescents aged 12 to 19 years (59%). Tooth decay is four times more common than asthma among adolescents aged 14 to 17 years (15%).

Many adults also have untreated tooth decay (e.g., 28% of those 35 to 44 years and 18% of those 65 and older).

Dentists over the years have tried many ways to identify and treat caries, especially in its early stages. Dental professionals have been exploring various ways to discover caries, especially the difficult-to-find interproximal type. The highly accurate2 DEXIS™ CariVu™ caries detection device can detect a range of carious lesions, including occlusal, interproximal, and recurrent, and even cracks, using near infrared transillumination technology. As the only near-infrared transillumination device available in the U.S. and Canada, CariVu yields a diagnostic image that looks like an X-ray, but with absolutely no ionizing radiation.

With CariVu, the size and shape of the lesion in the image corresponds well to the actual lesion. The healthy tooth appears light, and the lesions show up dark. This results in not just an indication of caries, but a more precise picture of caries. Other types of caries detection devices cannot offer this picture. Some may present an image with a range of colors, or a number correlated to a degree of mineralization, but with the CariVu, the caries is very viewable and readable—all there in black and white.

Dentists also can use the simple to understand black-and-white images to educate patients about their need for preventative or restorative care. And since the unit is fully integrated with the DEXIS system, the transillumination images can be displayed next to previously captured X-ray images for comparison and monitoring of the areas in question.

So, what’s black and white and read all over? Now you know…CariVu images!
