| zinc oxide | <chemical> A mild astringent and topical protectant with some antiseptic action. It is also used in bandages, pastes, ointments, dental cements, and as a sunblock. Pharmacological action: dermatologic agents, sunscreening agents. Chemical name: Zinc oxide (ZnO) (12 Dec 1998) |
| zinc oxide and eugenol | Used as a base material beneath metallic dental restorations and as a temporary filling material or impression material; setting and hardening result from complex reactions between the powder and the eugenol. (05 Mar 2000) |
| zinc oxide-eugenol cement | Least irritating of the cements. The powder is essentially zinc oxide with strengtheners and accelerators. The liquid is basically eugenol. (boucher's clinical dental terminology, 4th ed, p50) (12 Dec 1998) |
| zinc permanganate | Action is similar to that of potassium permanganate, but more astringent; used in urethritis, by injection or douche in a 1:4000 solution. (05 Mar 2000) |
| zinc peroxide | ZnO2;a yellowish white powder, insoluble in water and decomposed by acids; used in pharmaceutical preparations. Synonym: zinc superoxide. (05 Mar 2000) |
| zinc phenolsulfonate | Used as an intestinal antiseptic and locally as an astringent in chronic inflammation of the mucous membranes. Synonym: zinc sulfocarbolate. (05 Mar 2000) |
| zinc phosphate cement | <chemical> A material used for cementation of inlays, crowns, bridges, and orthodontic appliances and occasionally as a temporary restoration. It is prepared by mixing zinc oxide and magnesium oxide powders with a liquid consisting principally of phosphoric acid, water, and buffers. Chemical name: Phosphoric acid, zinc salt (2:3) (12 Dec 1998) |
| zinc phosphide | Zn3P2;used as a bait poison for the extermination of rats and mice. (05 Mar 2000) |

| zinc sulfate | <chemical> A compound given in the treatment of conditions associated with zinc deficiency such as acrodermatitis enteropathica. Externally, zinc sulfate is used as an astringent in lotions and eye drops. (reynolds jef(ed): martindale: the extra pharmacopoeia (electronic version). Micromedex, inc, englewood, co, 1995) Pharmacological action: astringents. Chemical name: Sulfuric acid, Zinc salt (1:1) (12 Dec 1998) |
| zinc sulfate flotation centrifugation method | A flotation method in which the faecal specimen is suspended in tap water, strained through wet gauze, centrifuged, resuspended in tap water, washed and recentrifuged several times, and then suspended in 33% solution of zinc sulfate and centrifuged at top speed for 45 to 60 sec; a bacteriologic loop may be used to pick up the surface layer, which contains protozoan cysts and helminth eggs.
