The Resonant Inelastic X-Ray Scattering or Resonant Raman Scattering (RRS) is an inelastic process of second order  that becomes  important when the energy  of  the  excitation  radiation is below but close  to  an absorption edge. In  this  process,  the  emitted photons have a continuous  energy distribution  with a highenergy cut-off limit. In  the  last  few  years experiments  of  RRS  has  become a very  powerful  technique to investigate excitations of electrons in solids [1,2]. A  study  of  the  oxidation  states  of  Ca  in  the  different layers  of  a  tooth  was  carried  out.  In  order  to  perform the  analysis,  several  measurements  of  tooth  samples  was  achieved  using  monochromatic  synchrotron radiation  at  the  XRF  station of  the  DO9B-XRF  bea
