Abstract
Osteoblast cells were used in an in vitro test to examine changes in cell adhesion on a magnesia partially stabilised zirconia (MgO-PSZ) bioceramic after CO2 laser treatment. The surface roughness, microstructure, crystal size and surface energy of untreated and CO2 laser treated samples were fully characterized. After 24 h cell incubation, no cells were observed on the untreated MgO-PSZ, whereas cells were seen to have attached onto the CO2 laser treated MgO-PSZ and exhibited spreading and good attachment. Moreover, the cell coverage density implied an increase in cell proliferation with increasing CO2 laser power density. Enhancement of the surface energy of the MgO-PSZ, especially its polar component, caused by the CO2 laser treatment was found to play a significant role in the initial cell attachment process, thereby leading to enhanced cell growth. Also, the change in topography induced by the CO2 laser treatment was identified as one of the factors influencing the osteoblast cell response.
