Cytotoxicity evaluation of three resin-based sealers on an L929 cell line
چکیده:   (1969 مشاهده)

 Background: Endodontic sealers usually come in contact with adjacent tissues and their biocompatibility is key in a successful treatment. The purpose of this study was to assess the cytotoxicity of three resin-based sealers, namely AH Plus, EndoREZ, and Epiphany in set and fresh states on an L929 cell line.

 Materials and Methods: In this in vitro experimental study, the materials were mixed according to the manufacturers’ instructions, and were divided into two groups, fresh and set. The elutes of materials were prepared separately and were incubated with L929 fi broblasts for 1 hour, 24 hours, and 72 hours. Pulp Canal Sealer and Dulbecco’s Modifi ed Eagle Medium (DMEM) served as positive and negative controls respectively. Cell viability was evaluated by MTT assay ([3-4,5-dimethyl thiazol- 2-yl]-2,5-diphenyltetrazolium bromide succinate), after 1 hour, 24 hours, and 72 hours. The data were analyzed by analysis of variance (ANOVA), and Tukey multiple comparison test.

 Results: After 1 hour, fresh Epiphany and fresh AH Plus were signifi cantly more cytotoxic than their set samples. No signifi cant difference was perceived between cytotoxicity of fresh state of sealers and positive control, or between set state and negative control. After 24 hours, both fresh and set samples of all materials were signifi cantly more cytotoxic than the negative control group, and were less cytotoxic than the positive control group. After 72 hours, the fresh and set samples of all materials were as cytotoxic as the positive control group. At each time point, no signifi cant difference was perceived among different materials in terms of cell viability.

  Conclusion: The observed differences among the cytotoxicity of AH Plus, EndoREZ, and Epiphany did not reach a signifi cant level at comparable time points after exposure.
