silver

 [sil´ver]
a chemical element, atomic number 47, atomic weight 107.870, symbol Ag. (See Appendix 6.) It is used in medicine for its caustic, astringent, and antiseptic effects. It is also used in dentistry in alloys, in soldering, and as cones to obliterate the root canal.
silver nitrate colorless or white crystals, used as a caustic and local antiinfective; an important use is in prevention of ophthalmia neonatorum.
silver protein silver made colloidal by the presence of, or combination with, protein; an active germicide with a local irritant and astringent effect.
silver sulfadiazine the silver derivative of sulfadiazine, having bactericidal activity against many gram-positive and gram-negative organisms, as well as being effective against yeasts; used as a topical antiinfective for the prevention and treatment of wound sepsis in patients with second and third degree burns.
toughened silver nitrate a mixture of silver nitrate with hydrochloric acid, sodium chloride, or potassium nitrate, occurring as white crystalline masses molded into pencils or cones; a convenient means of applying silver nitrate locally.
