Laser
Cavity Detection
Q: What is it?
This diagnostic tool helps us
detect cavities
on the
surfaces of teeth that previously were undetectable. Now
we can detect cavities at the earliest possible stage, so much
more conservative treatment can be performed.
This instrument allows us to be more accurate, with less guesswork.
Measurements from the Laser Scanner [Diagnodent] will help
us determine if certain suspected areas on the teeth
are decay
and
treat them with conservative
fillings, or to monitor them over time and treat
them with preventive therapies like fluoride and/or
sealants.
Q: How does
it work?
The Diagnodent uses a laser to help detect structural
changes in teeth. It actually measures the fluorescence
of the
different layers of the tooth structures. As the
laser light is shined
into the tooth, the special two way handpiece allows
the unit the measure the reflected light energy.
Clean, healthy tooth exhibits little
or no fluorescence, resulting in low readings on the display.
Cavities, however, do exhibit fluorescence when the laser
shines on
them. This results in a higher reading on the machine as
well as an audio signal.
