Abstract
This study was done to assess bond strength of Polycarboxylate cement reinforcedby different amount of Hydroxyapatite. In this study a hydroxyapatite materials wereadded to Polycarboxylate cement at different ratios;10%, 15%, 20%, 25% and 30% (by weight ) and the bond strength was detected by construction a cylinders from thesemixed materials, constructed on exposed dentine of human extracted premolar teethand by Zwick’s universal testing machine the bond strength were detected for thesemixed materials. Results showed that the Polycarboxylate reinforced byhydroxyapatite has higher bond strength than conventional Polycarboxylate cementand the hydroxyapatite powder to Polycarboxylate cement powder ratio by weightbest to be 20%. The addition of hydroxyapatite to conventional Polycarboxylatecement increased its bond strength to dentine.
