Human teeth were scratched by the abrasive paper, dropping in hydroxyapatite solution during 1, 2, 3, 4 months. We studied teeth surface change with SEM each months. After 1 months treatment the surface appeared the change. Because of the hydroxyapatite ion exchange mechanism. The scratched surface was recovered by the hydroxyapatite. The results of EDS showed that ion and ion were removed from hydroxyapatite solution to scratched teeth surface.

Keywords:Hydroxyapatite;Human Teeth;Ca2+ ion;PO3-4 ion
