Abstract
A model investigation was carried out to establish the chemical character of the bond between hard tooth tissues and polymeric materials. The interaction of NPG and NPG-GMA with Ca3(PO4)2 and 45Ca3(PO4)2 was studied in aqueous, alcoholic and aqueous-alcoholic solutions. It was shown that NPG and NPG-GMA react in solution with Ca ions which are in equilibrium with calcium phosphate. The reaction proceeds more intensively in aqueous-alcoholic medium due to its ionic character. The IR spectra of the reaction products show the presence of NPG-GMA calcium salt.
