What is the primary use of type II glass ionomer cement?

Type II glass ionomer cement is primarily utilized for restorative procedures, particularly in areas where there may be considerable stress or where aesthetics is a concern. It is specifically formulated for use in restorative applications, such as in cavity preparations where erosion has occurred, especially near the gingiva. This material is advantageous in such contexts due to its ability to release fluoride, which can help in the prevention of further decay and contribute to the overall health of the surrounding tooth structure.

While type II glass ionomer has applications that might overlap with some of the other choices, such as its use as a liner or base in cavity preparations, it is most recognized for its effectiveness in restoring eroded areas, especially in cases where the tooth may be at greater risk for caries or sensitivity. Its adhesive properties also allow it to bond well with the tooth structure, making it a reliable choice for restoring faulty or eroded surfaces.
