Novel Nanotechnology of TiO2 Improves Physical-Chemical and Biological Properties of Glass Ionomer Cement

Figure 3

Scanning electron microscopic images of human gingival fibroblast cells adhered to different substrates at 6, 24, 48, and 72 h: control (KM); KM + 3% TiO2; KM + 5% TiO2 and culture dish (cells). Normal cell morphology was observed for all groups: numerous cells, near confluence, remained adhering to the glass substrate and exhibited an elongated morphology with several thin cytoplasmic prolongations originating from their membrane and formation of layer of cells at 48 and 72 h (SEM original magnification 50x).
