silver /sil·ver/ (sil´ver) a chemical element, at. no. 47, symbol Ag.

---

silver nitrate  used as a local anti-infective, as in the prophylaxis of ophthalmia neonatorum.

silver protein  silver made colloidal by the presence of, or combination with, protein; it may be mild, used as a topical anti-infective, or strong, used as 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 compound of silver nitrate, hydrochloric acid, sodium chloride, or potassium nitrate; used as a caustic, applied topically after being dipped in water.

sil·ver (slvr)

n. Symbol Ag

A lustrous ductile malleable metallic element having the highest thermal and electrical conductivity of the metals and used in dental alloys and in pharmaceuticals. Atomic number 47.

silver (Ag)

Etymology: AS, seolfor

a whitish precious metal occurring mainly as a sulfide. Its atomic number is 47, and its atomic mass is 107.88. It is quite soft and is usually alloyed with small amounts of copper to increase its durability. Silver dissolves readily in nitric acid and is used extensively to produce silver halides used in photographic emulsions. It is frequently associated in small amounts with the ores of zinc, copper, and lead and is used extensively as a component of amalgams of dental fillings and in many medications, especially antiseptics and astringents. Some antiseptics containing silver are mild silver protein and strong silver protein, preparations that render silver colloidal in the presence of protein. Mild silver protein contains 19% to 23% silver. Strong silver protein contains 7.5% to 8.5% silver. Both preparations are used externally as antiseptics and do not have irritating properties. Silver nitrate is used externally as an antiseptic and astringent, especially in the prevention of ophthalmia neonatorum. It is also used as a lubricant on the bearings of radiography tubes, and silver halides are used in x-ray films. Silver picrate, an ionizable salt of silver, is used in the treatment of trichomoniasis and of moniliasis of the vagina.

silver nitrate, ammoniacal

n (ammoniated silver nitrate, Howe's silver nitrate), an ammonium compound of silver nitrate that is more readily reduced to silver and silver proteinates than is the usual silver nitrate; formerly used to disclose carious tooth structure and immunize incipient carious lesions of the enamel. It is highly irritating to the pulp and can permanently stain the oral mucosa.
