explore the suitable experimental conditions for enamel's biomimetic
mineralization, and to provide a basis for further study of the enamel's
regeneration in situ. Method: Collected 10 bicuspids which are need
extracted for orthodontic treatment. Firstly, constructed artificial caries
defect model, then prepared mineralize system solution which was used
to induce enamel to remineralization, cultivated it in artificial saliva for 4
weeks. And finally,took qualitative characterization of the surface
sediments by scanning electron microscopy (SEM) and electron energy
dispersive spectroscopy (EDS). Result:The solution containing dendrimer
can induce the deposited growth of short rod-like crystals on the
