This study evaluated the cytotoxicity of the root canal sealing materials Resilon and Epiphany versus guttapercha, Grossman's sealer, Thermaseal, and Sealapex. Using human gingival fibroblasts the fibroblasts cultures were incubated for either 1 or 24 h to test the cytotoxicity after freshly mixing or after 24 h of setting. Fibroblasts were then stained with trypan blue, to determine number of dead cells. Data were analyzed using ANOVA and t tests. Resilon was similar to guttapercha and the control. Epiphany was less cytotoxic than Grossman's sealer at both the 1 and 24 h time periods. Epiphany was more cytotoxic than Sealapex at the 1-h time period but less cytotoxic at the 24 h time period. These results indicated that Resilon had a lower cytotoxicity and that Epiphany was more cytotoxic than conventional materials.
