Cement dental materials, whose main component is ethoxy benzoic acid, designed to produce a mechanical interlocking effect upon hardening inside the mouth. These cements usually consist of a basic powder (zinc oxide, aluminum oxide) and an acidic liquid (ethoxy benzoic acid) that are mixed together in a viscous paste immediately before use, setting to a hard mass. Ethoxy benzoic acid cements have proper thermal and chemical resistance in the oral environment. They should be resistant to dissolution in oral fluids, and non-irritating to pulp and gingiva. These cements are used in dentists\' offices as sedative bases and for temporary restoration.
