The aim of this study was to assess the cytotoxicity of pure eugenol in an in vitro method by diluting it to various concentrations in alcohol and determining the maximum noncytotoxic concentration. We used solutions of eugenol and ethyl alcohol that are soluble in water in any given proportion. The cytotoxicity of the alcohol itself was determined by using a dose-response curve for concentrations of between 0.017 M and 1.7 M. Various strength concentrations (0.015 to 947 μm) of eugenol in alcohol were prepared; 20 μl (0.34 M) of ethyl alcohol was added to 1 ml of cell medium. The experiment showed that pure eugenol is toxic for human gingival fibroblasts. Eugenol in an alcohol solution at concentrations of <1.9 μm is noncytotoxic.
