Zinc oxide eugenol (ZOE) cements dental material, with hydrogenated resins added, designed to produce a mechanical interlocking effect upon hardening inside the mouth. ZOE cements consist of a powder (zinc oxide), a liquid (eugenol), a plasticizer (vegetable or mineral oil) and resins (polymethyl methacrylate) that are mixed together in a viscous paste immediately before use, setting to a hard mass. Reinforced ZOE cements have significantly higher strength than standard ZOE cements; they also have anesthetic and antibacterial properties, low thermal conductivity, and are non-irritating to pulp and gingiva. They are used in dentists\' offices for minor restoration (e.g., fractured teeth, lost restorations, advanced caries, pulpitis) and as temporary cementing medium and pulp capping.
