What is a typical characteristic of zinc phosphate cement?

Zinc phosphate cement is recognized for its strong and brittle nature, which is a typical characteristic that contributes to its effectiveness in dental applications. This material is frequently used for large restorations, as its strength makes it suitable for enduring the forces exerted in the oral environment. The brittleness often means that while it can withstand significant pressure during chewing, it may not flex or adapt to slight movements, leading to potential fracture under extreme conditions.

In contrast, the other characteristics mentioned do not accurately reflect the properties of zinc phosphate cement. It is not fluid or seamless, which rules out options that imply flexibility and adaptability. While it does have some aesthetic properties, such as a certain opacity, it is not generally described as colorless or odorless. Understanding these properties helps in selecting the appropriate material for specific dental procedures.
