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
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.
I am Dr. Louis Marion's daughter and I am entering my sophomore year as a BFA candidate as an Interdisciplinary Fine Arts major with a sculpture concentration at the University of the
Arts. I am also a member of the University of the
Arts Rumble Percussion Ensemble. We performed as an opening act
for Diana Ross at the 150 Anniversary Celebration for Albert
Einstein Healthcare Network at the National Constitution Center.
