The objective of this study was to improve the physical properties of Zinc Oxide Eugenal Cement in accordance with ISO 3107:1988 (E) type 3 class 1 which can be used as a temporary filling material. Test specimens were prepared from propionic acid conditioning zinc oxide BP and polymethyl methacrylate mixed with oil of clove or eugenal oil and concentrate acetic acid. Fourteen specimens were prepared and tested according to ISO 3107:1988 (E). Five specimens were tested for compressive strength by Instron Corporation Series IV Automated Material Testing System 7.43.00. The setting time was measured at 37゜c, while disintegration of 4 specimens were measured after 24 h. The cement fulfils the performance required by ISO 3107:1988 (E) type 3 class 1 for temporary filling materials and bases.The objective of this study was to improve the physical properties of Zinc Oxide Eugenal Cement in accordance with ISO 3107:1988 (E) type 3 class 1 which can be used as a temporary filling material.
