[Preparation of hard dental tissues by aeroabrasive method]

The efficiency of aeroabrasive preparation (AAP) of teeth was evaluated by clinical methods and scanning electron microscopy. The authors conclude that the use of AAP should be confined to the treatment of surface and medium caries. Analgesia before AAP is obligatory, except cases with preparation of fissures for preventive hermetization. The use of AAP is absolutely contraindicated in cases of allergic reactions in the patient, dentist, or assistant. Methods for protection of the dentist, assistant, and patient during the use of AAP are discussed.
