Materials and Methods
Fluorine compounds and cell culture. The fluorine compounds used in this study were sodium fluorosilicate (F6Na2Si, Fluka, Switzerland) and sodium fluoride (NaF, Sigma, USA)...
Results
Cytotoxicity of sodium fluorosilicate. To determine a concentration which leads to 50% growth inhibition (IC50 values), we performed cytotoxicity analysis by MTT assay. HOS, MG-63, KB and A-253 cells were treated with 0-250 ppm of sodium fluorosilicate or sodium fluoride. The cells were
