What is the function of type II cement in dental applications?

Type II cement, commonly referred to as glass ionomer cement, has various notable functions in dental applications, primarily as a restorative material. This type of cement is particularly valued for its ability to release fluoride, which helps in the caries prevention process. It is often used in situations requiring a strong bond to tooth structure and can effectively seal dentin, making it suitable for restorative procedures.

In addition to its restorative properties, Type II cement also has a good aesthetic quality, allowing it to be used in visible areas of the mouth, making it a practical choice for various situations including the restoration of Class V cavities. The cement bonds chemically to both the tooth enamel and dentin, providing essential support and stability for the restoration.

In contrast, the other functions listed do not align with the primary purpose of Type II cement. While it may have some role in the temporary coverage of teeth or in bonding orthodontic appliances, its primary utilization in restorative practices sets it apart as the best answer in this context. This understanding highlights the significance of selecting appropriate materials for specific dental functions and their contribution to dental healthcare.
