Which of the following is typically an example of Type one glass ionomer cement?

Type one glass ionomer cement is specifically designed for use as a luting agent for dental restorations or crowns. It is known for its adhesive properties and ability to bond chemically to both tooth structures and restorative materials, providing a durable and effective seal.

Ketac Fuji and Vitrebond are both examples of glass ionomer cements, but they are categorized differently. Ketac Fuji is often used in restorative applications rather than purely as a luting material, while Vitrebond is more accurately classified as a lining material. Dycal is a calcium hydroxide material used primarily as a liner for indirect pulp capping and does not fit the classification of glass ionomer cement.

In contrast, IRM Relax is formulated based on glass ionomer technology and is primarily used as an intermediate restorative material. However, it is not the correct terminology for Type one glass ionomer cement, which specifically refers to materials designed primarily for luting.

The correct response identifies the material that closely aligns with the characteristics and uses typical of Type one glass ionomer cement.
