| MIS | Meiosis-Inducing Substance |
| modified zinc oxide-eugenol cement | Dental cement obtained by mixing zinc oxide and eugenol with one or more additives. (05 Mar 2000) |
|---|---|
| composite dental cement | An organic dental cement modified by the inclusion of inorganic materials treated with a coupling agent to bond them to the polymers. (05 Mar 2000) |
| copper phosphate cement | A dental preparation, the combination of a solution of orthophosphoric acid with a cement powder (usually zinc oxide) modified with varying proportions of copper oxide. (05 Mar 2000) |
| polycarboxylate cement | Water-soluble low-molecular-weight polymers of acrylic or methacrylic acid that form solid, insoluble products when mixed with specially prepared zno powder. The resulting cement adheres to dental enamel and is also used as a luting agent. (12 Dec 1998) |
| silicate cement | <chemical> A relatively hard, translucent, restorative material used primarily in anterior teeth. Chemical name: Silicic acid, aluminum calcium salt (12 Dec 1998) |
| dental cement | <dentistry> Bonding substances available in the form of two components that are mixed together immediately before use, setting to a hard mass. They are used in restorative and orthodontic dental procedures as luting (cementing) agents, as bases, and as restorative materials. Resins and polymers used as restorative materials are usually called restorative resins rather than cements. (12 Dec 1998) |
| inorganic dental cement | A dental cement consisting usually of metallic salts or oxides which, when mixed with a specific liquid, form a plastic mass that sets. (05 Mar 2000) |
| organic dental cement | A dental cement consisting mainly of synthetic polymers. (05 Mar 2000) |
| tooth cement | <dentistry> A bony substance covering the root of a tooth. (08 Jan 1998) |
| 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 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) |
| unmodified zinc oxide-eugenol cement | A dental cement obtained by mixing zinc oxide and eugenol without modifiers. (05 Mar 2000) |
| alpha substance | A filamentous plasmatic material, beaded with granules, demonstrable by means of vital staining in the immature red blood cells. Synonym: alpha substance, filar mass, filar substance, substantia reticularis, substantia reticulofilamentosa. Synonym: reticular formation. (05 Mar 2000) |
| anterior perforated substance | A region at the base of the brain through which numerous small branches of the anterior and middle cerebral arteries (lenticulostriate arteries) enter the depth of the cerebral hemisphere; it is bordered medially by the optic chasm and anterior half of the optic tract, rostrally and laterally by the lateral olfactory stria; its anteromedial part corresponds to the olfactory tubercle. Synonym: substantia perforata anterior, locus perforatus anticus, olfactory area. (05 Mar 2000) |
| autacoid substance | A substance formed metabolically by one set of cells, which alters the function of other cells. (This term is sometimes used in place of the term hormone.) (05 Mar 2000) |
