Conservative Cavity Care Blasts Away Decay
Air abrasion is a relatively
new decay removal/tooth preparation procedure we often use in place
of the traditional dental drill. We find it useful
because it allows us to both conserve the patient's natural tooth structure
and reduce the risk of enamel micro-fracturing. It also entails minimal
discomfort, since the equipment does not produce vibration or heat,
thus requiring little or no anesthetic. It is also both quieter and faster
than using a drill.
So how does it work? Air abrasion applies the principle
of kinetic energy to bombard the tooth area with a high-pressure stream
of tiny
aluminum
oxide particles. As the particles bounce off the tooth's surface
they effectively blast away any existing decayed or damaged structure.
The
process requires only a minute or so per tooth. Considering these
factors, it's easy to see why air abrasion is a popular choice for working
with
children, as well as adults. While it's not appropriate for crown
and bridge preparation, it's useful in fissure reparation, discoloration
elimination and bonding procedure preparation.
