Which type of cement is known for having reinforcing agents added for permanent cementation?

The type of cement known for having reinforcing agents added for permanent cementation is ZOE type II. This formulation is specifically designed to enhance durability and strength, making it suitable for long-term procedures. The inclusion of reinforcing agents helps to increase the cement's mechanical properties, such as its resistance to fracture and wear, which is crucial for permanent cementation applications.

ZOE type II is particularly used in cases where additional strength is required, such as in the cementation of crowns and bridges, as well as in other restorations that need to withstand functional forces over time. This is a significant advancement compared to other types of zinc oxide-eugenol cements, which may not include these reinforcing agents and therefore may not offer the same level of strength and longevity in dental applications.
