Statement of Problem: With due attention to the control of quality of dental materials and its role in improvement of quality and accuracy of treatment, in this research, Zoiiran made in Golchai company was evaluated according to international standards.
Purpose: The aim of this study was the evaluation of properties of Zinc-oxide-eugenoi reinforced cement with trade name "Zoiiran".
Materials and Methods: According to ISO 3107, BS 7214, EN 23107 standards (1991), the number of samples were as follows: 2 for setting time, 5 for compressive strength, 4 for disintegration and 3 for film thickness testing. The experiments were followed standards instructions.
Results: Setting time was between 5.57-6.03 min. The compressive strength was between 21.29-25.79 MPa. Zoiiran had about 1.3-1.5 % disintegration. Finally, the film thickness was between 11-11.5 u.
Conclusion: According to mentioned experiments, physical properties of Zoiiran as temporary cement of fixed-prosthodontic (Typel-class I) and base liner (Type IV-class I), were similar to stated standards.
