Which of the following is considered a temporary cement?

Zinc oxide eugenol (ZOE) is classified as a temporary cement due to its unique properties that make it particularly suitable for short-term dental applications. ZOE is known for its soothing effect on the dental pulp due to the eugenol component, which has analgesic properties. This makes it ideal for temporary restorations or as a base under permanent restorations when there is a need to protect the dental pulp.

Moreover, ZOE sets relatively quickly and provides adequate retention for temporary situations, such as holding a crown in place until a more permanent solution can be applied. Its ease of use and good handling characteristics are additional factors that solidify its status as a preferred temporary cement in dental practices.

In contrast, materials like polycarboxylate and glass ionomer have properties that may allow them to be used for more long-term applications or permanent options, as they can bond chemically to the tooth structure, providing stronger retention. Resin, while versatile and used for various applications, typically serves as a material for more permanent restorations and does not have the same soothing properties associated with ZOE.
