Storage

  • Storage Conditions: Zinc oxide powder and eugenol liquid should be stored separately in their original containers, in a cool, dry place, away from moisture, heat, and direct sunlight.
  • Usage: Containers must be tightly closed to prevent contamination and evaporation of eugenol. The cement should be used immediately after mixing, as it hardens upon setting.
  • Zinc eugenol cement is valued in dental practice for its pain-relieving and soothing properties, offering temporary relief during restorative procedures.
