The erosion of zinc polycarboxylate cements by water was studied by chemical techniques. In three months, the elution rate diminished. The erosion pattern of each cement was related to the type of polyacid present in the cement. Relatively large amounts of magnesium were eluted. A mechanism of hydrolysis is proposed.
ventional dental cements such as Zinc Polycarboxylate and Zinc Phosphate is their low mechanical strength (4,7-9), nanoparticles can solve their shortcomings. However, a few previous studies have incorporated Zinc oxide nanoparticles into dental cement and they have reported controversial results about mechanical improve-ment (2,3).

Zinc Polycarboxylate . Invented in 1968, zinc polycarboxylate cement was the first cement to exhibit a chemical bond to tooth structure. 1 Very little pulpal irritation is seen with its use due to the large size of the polyacrylic acid molecule. 4 The many uses of this cement include permanent cementation of crowns, bridges, inlays, onlays, and

3- Zinc polycarboxylate cement: Zinc polyacrylate cements (or zinc polycarboxylate) are supplied as a powder and a liquid or as a powder that is mixed with water. The liquid is a water solution of polyacrylic acid (32% to 42%). The cement powder is essentially zinc oxide and magnesium oxide.

This cement was developed by Dr. Dennis Smith, a Manchester dentist in 1968 as a basic set of two liquids and one powder. One liquid was used for luting purpose, while the other for lining purpose. He replaced phosphoric acid with a new polymeric acid, polyacrylic acid and it was the first chemically adhesive cement.
Zinc Polycarboxylate cement was the First cement that was developed with the property of an adhesive bond to tooth structure along with some metallic cast restorations. COMPOSITION: Zinc Polycarbolylate cement is available as powder and liquid Also as a Water settable cement in which the
cavity [6]. Zinc polycarboxylate cement is a water-based material that hardens following an acid-base reaction between zinc-rich powder and an aqueous solution of polyacrylic acid [7,8]. Since its invention in 1968, zinc polycarboxylate cement has been widely used to cement inlays and crowns and to make bases [9].
