The principal cements are silicate cements, zinc phosphate cements, silicophosphate cements, polycarboxylate cements, glass ionomer cement (gic), and zinc oxide and eugenol cement (stanley and schmalz, 2009). silicate cements are common filling materials; however, they are associated with pulp damage when applied without a cavity base.

Today, dentistry is rapidly moving from cementation of alloybased restorations with traditional cements (eg, glass ionomer, resinmodified glass ionomer, zinc phosphate, zinc polycarboxylate) to bonding of allceramic restorations with resinbased cements. these resinbased cements include esthetic resins, adhesive resins, and selfadhesive.

Traditionally, zinc phosphate cement has been the most popular luting material despite its welldocumented disadvantages, particularly, solubility and lack of adhesion. 74 cements like zinc phosphate, zinc oxide eugenol, zinc oxide ethoxy benzoic acid (super eba), polycarboxylate and glass ionomer, provide primarily mechanical retention, since adhesion was estimated to be too low for.
