What procedure can Glass Ionomer cement be used for?

Glass Ionomer cement is widely recognized for its diverse applications in dentistry, particularly due to its strong chemical bond with tooth structure and its release of fluoride, which can aid in caries prevention. It is most commonly utilized for restorative fillings in primary teeth, especially in pediatric dentistry, because it is biocompatible and can provide a good margin seal against microleakage.

In the context of the provided options, the choice regarding post and core build-up stands out because glass ionomer can be used effectively in situations requiring the restoration of a tooth that has undergone significant loss of structure, particularly due to endodontic treatment. Due to its strength, compatibility with tooth structure, and ability to bond well, glass ionomer cement is ideal for core build-ups that will support a crown.

Additionally, its properties make it a less favorable choice for permanent restorative fill in posterior teeth when under function or for high-stress applications, such as orthodontic band cementation and veneer placement. Composite resin materials are typically preferred for these procedures due to better mechanical properties and esthetics. Therefore, post and core build-up using glass ionomer cement is highly suitable given its particular advantages in that relevant clinical situation.
