Correct Answer:

Oil of orange

Description:

MANIPULATION Powder/liquid system: Powder/liquid ratio - 4:1 to 6:1 by weight. The bottles are shaken gently. Measured quantity of powder and liquid is dispensed onto a cool glass slab. The bulk of the powder is incorporated into the liquid and spatulated thoroughly in a circular motion with a stiff bladed stainless steel spatula. Zinc oxide eugenol exhibits pseudothickening. Although it appears to thicken early during spatulation, further vigorous spatulation or stropping loosens the mix. Smaller increments are then added, until the mix is complete. For temporary restorations, a thick putty-like consistency is recommended. Oil of orange is used to clean eugenol cement from instruments. Reference – Manappallil p; 101
