The primary purpose of this study is to investigate the degree to which we can improve the prediction of rodent carcinogenicity (CA) by combining results from an in vitro and two in vivo genotoxicity tests. We used the Ames Salmonella assay (SAL) for the in vitro test and the micronucleus assay (MNC

โฆ Synopsis
In a comprehensive assessment of genotoxicity, sodium fluoride was evaluated in a battery of cellular tests providing different genetic end points and biotransformation capabilities. The tests included the following: rat hepatocyte primary culture/ DNA repair assay, Salmonella typhimurium histidine locus reversion assay, adult rat liver epithelial cell/ hypoxanthine guanine phosphoribosyl transferase mutation assay, and sister chromatid exchange in two target cell types, human peripheral blood lymphocytes and Chinese hamster ovary cells. Negative findings were made in all assays, indicating that sodium fluoride is not genotoxic in these assays.
