In 3D TV, two images are taken from two different cameras that are close to each other, similar to our eyes. The left image is colored blue-green (cyan) and the right image is colored red before they were combined for 3D viewing. The superimposed images look blurred. But when you put on 3D glasses , the filters in the
Air Abrasion
An instrument that works like a mini sandblaster is used to spray away decay. During air abrasion, a fine stream of particles is aimed at the decayed portion of the tooth. These particles are made of silica, aluminum oxide, or a baking soda mixture and are propelled toward the tooth surface by compressed air or a gas that runs through the dental handpiece. Small particles of decay on the tooth surface are removed as the stream of particles strikes them. The particles of decay are then "
