Objective: This in vitro study evaluated the cytotoxic effects of the Curcuma zedoaria (Christm.) Roscoe (popular name: zedoary) fluid extract, as used in preparations for oral hygiene, mostly for anti-septic purposes. Materials and methods: The cell viability and cell growth were assessed by Trypan blue dye exclusion assay using the LMF cell line derived from oral mucosa. Cell viability (short-term assay) was measured 0, 6, 12 and 24 h after contact with the fluid extract. Cell growth (long-term assay) was analyzed in 1, 3, 5 and 7 days. The experimental groups were those testing the fluid extract obtained from the zedoary rhizome and the extractor liquid (ethanol 70° GL) in the concentrations of 0.01-0.0001% v/v. Fresh DMEM were used in the control cultures. Results: Short-term assay - all studied cultures maintained stable cell viability; Longterm assay - there was progressive cell growth in all studied cultures. Conclusion: According to the results, the zedoary fluid extract presents low cytotoxicity and probably can be used in the oral hygiene products. © 2012 Informa Healthcare.
