Polycarboxylate Cement contains 2 or more monomers and is used as permanent cement for cast restorations, stainless steel crowns, and orthodontic bands.

• A. Polycarboxylate Cement
• B. Zinc-Oxide Eugenol Cement
• C. Dissipate
• D. Provisional

Answer: (A)

The main idea here is identifying the cement used for permanent bonding to both tooth structure and metal surfaces. Polycarboxylate cement is a permanent luting agent that sets by reacting zinc oxide with a liquid containing polyacrylic acid. Its standout feature is the chemical bond it can form with dentin and enamel through calcium ions, which helps it grip tooth surfaces firmly while also adhering to metal such as cast restorations, stainless steel crowns, and orthodontic bands. This combination of chemical adhesion and durable strength makes it well-suited for long-term cementation of these restorations.

Zinc-oxide eugenol cement is typically used as a temporary or sedative cement rather than for permanent restoration cementation. Provisional points to a temporary cement or material, not a permanent luting agent, and dissipate isn’t a cement type.
