Temporary filling materials

Zinc oxide phosphate cement
Powder: ZnO (90%), MgO (10%), pigments.

Fluid: H3PO4.

Application: fixation of crowns, superstructures and bridges, temporary filling, amalgam pad.

Polycarboxylate cement
Powder: like zinc oxide phosphate cement.

Fluid: polycarboxylic acid.

Application: temporary filler, carburization, washer.

Zinc oxideugenol cement
Powder: ZnO, synthetic resin, accelerators, rosin.

Liquid: eugenol, olive oil.

Application: as a sealer in endodontics, for temporary sealing of final fixed structures, EBA cements can also be used for final sealing.

Properties: does not have dentinoplastic effects, disrupts polymerization of composites, is not mechanically resistant, allergizes and discolors tooth tissues.

Zinc oxide sulfate cement
Powder : CaSO4, ZnO, ZnSO4. (For better workability, glycol acetate, polyvinyl acetate, dextrin are added to this powder)

Fluid: H2O.

Application: trepanation hole closure.

Silicate cement

 * Fluoro-aluminium-calcium-silicate glass and phosphoric acid.

Cements s Ca(OH)2
Use: as a sealer in endodontics, pad under the final filling, for direct and indirect covering of the medulla.
