DEXIS CariVu is a portable cavity detection device that uses unique, transillumination technology to support the identification of cavities and cracks.
CariVu hugs the tooth and bathes it in safe, near infrared light. On the resulting images, enamel appears transparent while lesions appear as dark areas. This allows us to see through the tooth, exposing its structure and the actual shape and size of any cavity with very high accuracy.
CariVu is a wonderful adjunct to digital x-ray imaging. It helps to fill in the gaps. It is designed to locate cavities and cracks where x-rays may be limited. It also has been shown to spot caries sooner than with digital x-rays alone.
