Use of an acidic chemical substance to prepare the tooth enamel and or dentin surface to provide retention for bonding.

This process for the decoration of glass involves the application of hydrofluoric acid to the glass surface. Hydrofluoric acid vapours or baths of hydrofluoric acid salts may be used to give glass a matt, frosted appearance (similar to that obtained by surface sandblasting), as found in lighting glass.

A method of marking or decorating a surface. In acid etching an acid resistant stencil of the artwork or text is applied to the chosen surface. A corrosive compound such as hydrofluoric acid is then a [..]

A technique that uniformly thins CCDs to approximately 10 µm so that an image can be focused on the back of the parallel register (where there is no gate structure). See back-illuminated CCD.
