etching

 [ech´ing]
the cutting of a hard surface such as metal or glass by a corrosive chemical, usually an acid, in order to create a design.
acid etching etching of dental enamel with an acid in order to roughen the surface, increase retention of resin sealant, and promote mechanical retention.

acid etching

microscopic roughening of dental enamel with an acid (usually phosphoric acid) to remove the smear layer and open enamel tubules, increase retention of resin sealant, and promote mechanical retention.

acid etching

Dentistry
The application of a weak acid—e.g., 30% phosphoric acid—to the surface of enamel to roughen the surface of a tooth before bonding a resin or veneer; acid etching increases mechanical retention, cleans the enamel and improves the wetting of resins. See Cosmetic dentistry.

ac·id etch·ing

(asid eching)
Treatment of tooth surfaces with phosphoric acid solution to roughen tooth structure microscopically to create retention, usually for resin-type restorations.
