ZOE (Zinc Oxide eugenol) cement is excessively used in dentistry since 1980s, depending on their use they vary widely in their properties. Zinc oxide eugenol cements are of low strength and they are least irritating of all dental cements and are known to have an outbound effect on dentin.<\/p>\n\n\n\n

\u2022 Compressive strength- This is a relatively weak cement ranges from a low of 3-4 MPz up to 50-55 MPz
\u2022 Tensile strength- Tensile strength ranges from 0.32 to 5.3 MPa
\u2022 Modules of elasticity- 0.22 to 5.4 GPa
\u2022 Thermal Properties- thermal properties of ZOE are excellent
\u2022 Solubility and disintegration- The solubility of the set cement is the highest of all the cements, they disintegrate in oral fluids
\u2022 Adhesion- ZOE cement do not adhere well to the enamel and dentin, this is one reason why they are not often used for final cementation of crowns and bridges.
