What is temporary filling
The material constituting the temporary filling, is composed of a mixture of zinc oxide and eugenol. Eugenol is the active substance known for its sedative properties. It is found in nature as oils and has a characteristic smell and taste like cloves. The zinc oxide powder behaves differently depending on the ingredients with which it is mixed. In temporary fillings, it is used to give hardness to the eugenol. When these substances are mixed, they first form a soft and sticky solution, which then becomes more rigid and fragile.
