Zinc-Oxide Eugenol (ZOE) Cement is described as one of the most versatile cements, can be used as a base.

• A. One of the most versatile cements, can be used as a base.
• B. A plastic setting resin.
• C. A polymer used for bonding to metal.
• D. Only for temporary crowns.

Answer: (A)

Zinc-Oxide Eugenol cement earns its versatility from a combination of practical clinical properties. The eugenol component provides a soothing, sedative effect on the pulp, which helps when working near or exposing the dentin. It also mixes easily, sets to a workable hardness, and can be removed relatively cleanly when a restoration is taken out. Because of its insulating qualities and gentle handling, it functions well as a base or liner under restorations, protecting the tooth structure while not being so rigid that it would cause overly high stresses.

This makes it a good description for being “one of the most versatile cements” and specifically suitable as a base. It’s not a plastic setting resin, nor is it a polymer used for bonding to metal, so those roles don’t match ZOE’s chemistry. It’s also not restricted to temporary crowns; while it’s commonly used for temporary cementation, its base and lining applications are important too. Keep in mind that its low strength means it’s not ideal for permanent structural bases under heavy occlusion, and the eugenol can interfere with some resin bonding if used in certain adhesive restorations.
