To unite or make firm by or as if by cement; to lute.
Substance used to bind surfaces or objects together. Commonly stored as separate powder and liquid components that, when mixed together, become a luting agent upon hardening. To cement is to join surfaces by means of an appropriate medium.
A substance used in dentistry to fix into place an inlay, bridge, or artificial crown or to form a filling. Cements used for fillings are pastes that harden rapidly, usually zinc phosphate obtained by mixing zinc oxide powder with phosphoric acid. Copper cements, prepared from copper oxides, are antibacterial but stain the teeth. The newer polycarboxylate cements are prepared using polycarboxylic acid. Silicate cement is a synthetic porcelain prepared from a silica-based powder mixed with phosphoric acid, which forms a translucent material. It is used for white fillings for front teeth.
Any material that hardens into a firm mass when prepared appropriately.
