Role Of Abrasives In Dentistry
Abrasion: It occurs when a hard rough surface slides along a softer surface and cuts a series of grooves. The wearing away of a substance or a structure through a mechanical process such as grinding, rubbing, or scraping.
Polishing: It is the production of a smooth mirror-like surface without much loss of an external form. If the particle size of the abrasive is reduced sufficiently the scratches become extremely fie and may disappear entirely. The surface then acquires a smooth shiny layer known as polish.
