Which method is most effective for controlling the setting time of Zinc Oxide Eugenol (ZOE)?

Show Answers

Incorporating a small amount of eugenolIntroducing a few drops of waterLowering the temperature of the glass slabChanging the proportion between the two componentsIncreasing the mixing speed

Explanation

The setting time of Zinc Oxide Eugenol (ZOE) is best regulated by cooling the glass slab during mixing. This temperature reduction slows the chemical reaction, allowing better control over the setting process. Adding eugenol or water, or adjusting the paste ratio, has less impact on setting time compared to temperature control.
