New Tech in Dr. Marion's office: CariVu
Last summer, Dr. Louis Marion acquired and trained his staff with a new technology for diagnosis of dental problems, the Dexis CariVu. CariVu is a transillumination technology that gives Dr. Marion and the patient, the ability to see into, and around any the tooth like never before. It provides topographic and internal tooth structure illumination, as well as the visual detection of problems like cracks and decay. And the amazing asset regarding this technological advance is that it does all this without any additional radiation. 
CariVu looks like a wand.  It is actually a USB camera.  This small and portable device helps Dr. Marion and his dental team identify cracks, decay, or other unhealthy developments on or in the tooth. Dental structures are the hardest structure in the body. Cracks and even decay can be difficult to image.  CariVu takes advantage of the fact that teeth are translucent; that is, they let light pass through partially and therefore can be illuminated.  The CariVu has two light sources built-in to its head to do the illuminating.  The head is flexible to it can hug any size tooth and light it up.  The center of the head has a camera that shows the tooth on screen as it is lit up, giving us a sort of inside look at its structure.  Problems like cracks and decay alter the density of the tooth structure and therefore absorb the light.  These pathologies then show up as dark crack lines or blotches of darkness on the monitor.
CariVu is compatible and fully integrated with Dr Marion’s practice software called Dentrix.  As many of you know, Dr. Marion and his staff were specially trained two years ago to do paperless charting and utilize all facets of digital imaging and communication.  The CariVu images can therefore be emailed instantly to your referring specialists if the problem is of a more serious in nature.  Referring doctors have loved this as it often can eliminate the need for further x-ray imaging like the computer tomography or CT scans.  CariVu images are produced without any radiation dosage to the patient.   

Dr. Marion and his staff are proud of the technology and will show it to you the next time you come in.  Recently a patient came in for a second time for dental pain in a specific area.  The first time was before we had the CariVu technology.  The CariVu imaged the crack and the tooth was treated and saved before it needed more invasive procedures like root canal therapy or crown.

I inserted images of the CariVu and what it can do:
A)  This image shows the CariVu head with its flexible arms and two light sources and the camera lens in the center (see image above).
B)  This second image was produced on screen by the CariVu.  It picked up decay in between the tooth and its neighboring tooth.  Without CariVu, the healthy tooth structure on either side of the problem (cavity) block the visibility by the naked eye or a conventional x-ray.
C)   This image below shows clear cracks around this tooth’s perimeter.  This tooth’s x-ray did not demonstrate any pathology even though the patient felt pain to chewing.
