A simple method to protect patient and environment when using sandblasting for intraoral repair

Repair or correction of intraoral restorations can be an alternative to complete replacement. A simple sandblasting device is very effective in producing a microretentive surface on every restorative material. A disadvantage of the technique is the production of an aerosol contaminated with the small, abrasive aluminum-oxide particles. In this article, a simple solution is given to protect the patient and environment against this dust during intraoral reparatory procedures involving sandblasting.
