Question: 1 / 400

How does polycarboxylate cement bond to enamel?

Mechanically

By micro mechanical retention

Chemically

Polycarboxylate cement chemically bonds to enamel by forming bonds with the calcium ions in the enamel. This allows for a strong and durable bond between the cement and the tooth. Options A and B, which suggest a mechanical bond, are incorrect as polycarboxylate cement does not rely on physical grip for its bonding mechanism. Option D, which suggests fusion at high temperatures, is incorrect as polycarboxylate cement does not require high temperatures for its bonding process.
