title: Comparison of cell proliferation on modified dental ceramics.
abstract: The aim of this study was to investigate the influence of substrate characteristics such as chemical composition and surface morphology of dental ceramics to support cell attachment and proliferation. Thus, body (B) and shoulder (S) porcelain differing on their surface morphology and composition were treated with oxides CaO or CaO and P(2)O(5) and four modified ceramics BCa, BCaP, SCa, SCaP were constructed, respectively. The modified ceramics differ from their controls concerning their surface morphology as evaluated by Scanning Electron Microscope (SEM), and their surface chemical composition (Na, KP and Ca) as evaluated by Energy Dispersing Spectroscopy (EDS). All modified ceramics support better than the control ceramics the cell proliferation over 72 h incubation period. Furthermore, higher rates of cell proliferation was detected in shoulder modified ceramics (SCa and SCaP) than in all other cases.
