| cement | <dentistry> A nonmetallic material used for luting, filling, or permanent or temporary restorative purposes, made by mixing components into a plastic mass that sets, or as an adherent sealer in attaching various dental restorations in or on the tooth. Synonym: cementum. Origin: see cementum (05 Mar 2000) |
|---|---|
| cement base | <dentistry> A layer of dental cement, sometimes medicated, that is placed in the deep portion of a cavity preparation to protect the pulp, reduce the bulk of a metallic restoration, or eliminate undercuts. Synonym: cavity preparation base. (05 Mar 2000) |
| cement corpuscle | <dentistry> A cementocyte contained within a lacuna or crypt of the cementum of a tooth; an entrapped cementoblast. (05 Mar 2000) |
| cement line | The refractile boundary of an osteon or interstitial lamellar system in compact bone. (05 Mar 2000) |
| resin cement | A monomer or monomer/polymer system used as a dental luting agent; used in cementation of restorations or orthodontic brackets to the teeth. (05 Mar 2000) |
| 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) |
| intercellular cement | A hypothetical adhesive substance formerly believed to occur between some epithelial cells. (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) |
