Character of the hard tooth tissue-polymer bond. I. Study of the interaction of calcium phosphate with N-phenylglycine and with N-phenylglycine-glycidyl methacrylate adduct
C. Alexieva
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.
