study of demineralized and remineralized enamel and hydroxyapatite using nuclear magnetic resonance (nmr)

ABSTRACT

The study was conducted to observe if there is any difference in the chemical structure of demineralized and remineralized enamel and hydroxyapatite using solid state 3IP MAS NMR techniques. Chemical structure and composition of enamel and hydroxy apatite powder were analyzed using different acids i.e. hydrochloric acid, citric acid and acetic acid, of different molarities, followed by treatment in remineralizing solution for a time period of 1, 3, 6 and in some cases 7 days, using NMR. We expected to change current concepts of remineralizing and demineralizing processes of enamel and hydroxy apatite
