From: Behavior of osteoblastic cells cultured on titanium and structured zirconia surfaces
Cell proliferation rates of osteoblasts on differently coated surfaces at day 1, 3 and 5, respectively. Increase in cell number was detected on all surfaces over the observation period. Significantly higher cell proliferation was observed on zirconia surfaces on day 1, 3 and 5 compared to titanium and polystyrene surfaces. Statistical differences (p < 0.05) as calculated by Student's t-tests are marked with arrows.
