Cell proliferation of MC3T3-E1 cells on 700, 800, 900, and 1000 °C TiO2 samples and Celldesk LF1 (Polystyrene film dish). Optical density is equivalent to the number of cells. A significant difference in cell proliferation was identified every group on day 7 of culture (p < 0.05). On day 14, with the same letter indicating that there is no significant difference between the groups (p < 0.05).
