One of the main objectives of contemporary dentistry is to preserve healthy
tooth structure by applying techniques of noninvasive treatment. Air abrasion
is a minimally invasive nonmechanical technique of tooth preparation that
uses kinetic energy to remove carious tooth structure. A powerful narrow
stream of moving aluminum-oxide particles hit the tooth surface and they
abrade it without heat, vibration or noise. Variables that affect speed of
cutting include air pressure, particle size, powder flow, tip’s size, angle
and distance from the tooth. It has been proposed that air abrasion can be
used to diagnose early occlusal-surface lesions and treat them with minimal
tooth preparation using magnifier. Reported advantages of air abrasion
include reduced noise, vibration and sensitivity. Air abrasion cavity
preparations have more rounded internal contours than those prepared with
straight burs. This may increase the longevity of placed restorations because
it reduces the incidence of fractures and a consequence of decreased internal
stresses. However, air abrasion cannot be used for all patients, i.e. in
cases involving severe dust allergy, asthma, chronic obstructive lung
disease, recent extraction or other oral surgery, open wounds, advanced
periodontal disease, recent placement of orthodontic appliances and oral
abrasions, or subgingival caries removal. Many of these conditions increase
the risk of air embolism in the oral soft tissues. Dust control is a
challenge, and it necessitates the use of rubber dam, high-volume evacuation,
protective masks and safety eyewear for both the patient and the therapist.
