Zinc oxide is an inorganic compound with the formula Zn O.It is a white powder which is insoluble in water. ZnO is used as an additive in numerous materials and products including cosmetics, food supplements, rubbers, plastics, ceramics, glass, cement, lubricants, [12] paints, sunscreens, ointments, adhesives, sealants, pigments, foods, batteries, ferrites, fire retardants, semi conductors ...
Zinc peroxide (ZnO 2) is a chemical compound of zinc that appears as a bright yellow powder at room temperature. It was historically used as a surgical antiseptic. More recently zinc peroxide has also been used as an oxidant in explosives and pyrotechnic mixtures. Its properties have been described as a transition between ionic and covalent ...
Zinc oxide eugenol is also used as an impression material during construction of complete dentures and is used in the mucostatic technique of taking impressions, usually in a special tray, (acrylic) produced after primary alginate impressions. However, ZOE is not usually used if the patient has large undercuts or tuberosities, whereby silicone ...
Zinc toxicity is a medical condition involving an overdose on, or toxic overexposure to, zinc. Such toxicity levels have been seen to occur at ingestion of greater than 50 mg of zinc. [1] [unreliable medical source?] Excessive absorption of zinc can suppress copper and iron absorption. The free zinc ion in solution is highly toxic to bacteria ...
Zinc oxide eugenol (ZOE) was the first agent to be used for preservation. In recent years, glutaraldehyde has been proposed as an alternative to formocresol based on: its superior fixative properties and low toxicity. A nonaldehyde chemical, ferric sulfate, has received some attention recently as a pulpotomy agent.
Zinc oxide/eugenol cements: Supplied as two pastes or as a powder (zinc oxide) and liquid (zinc acetate, eugenol, olive oil) A slow chelation reaction of two eugenol molecules and one zinc ion to form zinc eugenolate without moisture. However, setting can be completed fast when water is present. Bactericidal effect due to free eugenol
Side effects may include abdominal pain, vomiting, headache, and feeling tired. [2] While normal doses are deemed safe in pregnancy and breastfeeding, the safety of larger doses is unclear. [3] Greater care should be taken in those with kidney problems. [2] Zinc is an essential mineral in people as well as other animals. [4]
The first drug used for this purpose was curare, introduced in the 1940s, which has now been superseded by drugs with fewer side effects and, generally, shorter duration of action. [42] Muscle relaxation allows surgery within major body cavities , such as the abdomen and thorax , without the need for very deep anaesthesia, and also facilitates ...
