What is polycarboxylate cement?
Polycarboxylate cement is one of the few dental materials that demonstrate true adhesion to tooth structure. The powder is primarily zinc oxide, and the liquid is polyacrylic acid or a copolymer of that acid. One means of cleaning the surface is a 10- to 15-second swabbing with 10% polyacrylic acid.

How do luting cements work?
Luting agents work by attaching dental restorations like crowns and bridges to a tooth surface. You’d think that, because of the word ”cement,” they would only bond the restoration to the tooth using really strong chemical bonds.
Is composite A resin cement?
Resin cements are the luting agents of choice for bonding metal, ceramic and indirect composite restorations. Most resin cements are radiopaque and release small amounts of fluoride. Resin cements are used with bonding agents when bonded to tooth structure.
What is dual-cure resin cement?
