CariVu Technology – Caries Detection Device


DEXIS CariVu™ is a compact, portable caries detection device that uses patented transillumination technology to support the identification of decay and cracks in the teeth. By hugging the tooth and bathing it in safe, near-infrared light, CariVu’s transillumination technology makes the enamel appear transparent while porous lesions trap and absorb the light. This unique caries detector allows Dr. Samaddar to see through the tooth exposing its structure and the actual structure of any carious lesions with very high accuracy. Similar in appearance, DEXIS CariVu images read like familiar X-ray images —decay will appear as dark areas. This provides an edge over fluorescent imaging technologies in that there is no need to clean the tooth of bacteria, calibrate the device or become versed in the meaning of multiple color codes or numeric indicators.


Dr. Sheila Samaddar is a friend, neighbor, and my new dentist! As a patient of hers, I can tell you she is very gentle!
