title: The effect of an air-powder abrasive instrument on composite resin.
abstract: Three composite resins were subjected to applications of sodium bicarbonate with an air-powder abrasive instrument. Materials tested were a microfilled, a conventional, and a light-cured composite resin. Samples were tested for surface roughness before and during applications. The applications produced significant increases in roughness. It was concluded that the light-cured composite resin should be the material used for patients undergoing a recall maintenance program in which the instrument is used.
