What is an advantage of using zinc phosphate as a dental material?

• A. It is moisture sensitive
• B. It provides a stronger base under restorations
• C. It adheres poorly to dentine
• D. It is difficult to control the setting time

Answer: (B)

Using zinc phosphate as a dental material offers several notable advantages, one of which is its ability to provide a stronger base under restorations. This strength is particularly beneficial because it can support the restoration, alleviate stress on the underlying tooth structure, and contribute to overall durability. The material's strength also aids in withstanding the forces of mastication, making it a reliable choice for various dental applications, especially when used as a base or liner under restorations. While it has some drawbacks—such as being moisture sensitive, adhering poorly to dentine, and having a challenging setting time—these aspects do not negate its efficacy as a strong base material. The mechanical properties of zinc phosphate make it an excellent choice when a robust foundation is needed, helping to ensure long-lasting outcomes for dental restorations. Understanding these characteristics allows dental professionals to make informed decisions on material selection based on the needs of each specific case.
