Scanning electron micrographs of platelet morphologies after 1-hour adhesion period on (i) panogramic image of 30 stitched images of the surface wetted with platelet-rich plasma (PRP) at x2500 magnification. (ii) x10000 magnification of platelet morphologies. (a) Non-coated zirconia, (b) zirconia coated with TiO₂, and (c) zirconia coated with TiO₂ irradiated with ultraviolet radiation. Note. White arrows show platelets; black arrows show red blood cells.
