However, these compounds may represent a hazard to human health, especially by causing injury to genetic apparatus and/or inducing cellular death. In this study, the genotoxic and cytotoxic potentials associated with exposure to chloroform and eucalyptol were assessed on mouse lymphoma cells in vitro by the single cell gel (comet) assay and trypan blue exclusion test, respectively. Both gutta-percha solvents proved to be cytotoxic at the same levels in concentrations of 2.5, 5 and 10 μL/mL (p<0.05). On the other hand, neither of the solvents induced DNA breakage. Taken together, these results suggest that although both tested compounds (chloroform and eucalyptol) are strong cytotoxicants, it seems that they are not likely to increase the level of DNA damage on mammalian cells.228-232engChloroformCytotoxicityEucalyptolGenotoxicityMouse lymphoma cellschloroformcineolecoloring agentcyclohexanol derivativediagnostic agentDNAgutta perchamutagenic agentsolventterpenetrypan blueanimalcell survivalchemistrycomet assayDNA strand breakagedrug effectEucalyptusleukemia L 5178 YmousepathologyAnimalsCell SurvivalColoring AgentsComet AssayCyclohexanolsDNA BreaksGutta-PerchaLeukemia L5178MiceMonoterpenesMutagensSolventsTrypan BlueArtigo10.1590/S0103-64402006000300010S0103-64402006000300010Acesso aberto2-s2.0-339475220512-s2.0-33947522051.pdf50511187529809037528116925519142
