In this study, we formed TiO_2 layers on the titanium surface using micro-arc oxidation methods and analyzed the effect of polarized TiO_2 on osteoblast like cell activity. The surface characterization of oxide layer was examined by X-ray diffraction, scanning electron microscopy, energy disperse X-ray spectroscopy, laser scanning microscopy and sessile drop technique. Confirmation of the polarization charges was examined by the thermally stimulated depolarization current method. However, there was no difference in morphology between non-polarized and polarized titanium, contact angle of water was and the stained area of ALP-positive cells were increased by the electric polarization.
