Cytotoxicity of current adhesive systems: in vitro testing on cell culture of L929 and balb/c 3T3 fibroblasts
AbstractPurpose: The aim of this study was to evaluate the cytotoxicity of three current adhesives: Prime&Bond NT (PBNT), Single Bond (SB) and XENO III (XENO). Methods: After embedding and curing circles of filter paper with the tested adhesives, the filters were placed in contact with the solidified agar surface over L929 monolayer cells plated in 6-well cell culture plate and incubated for 24 h. The inhibition zone around the filter papers was measured in mm. MTT assay was performed using fibroblasts Balb/c 3T3 cell lines in multiwell culture plates. All assays were done in triplicate. Results: All materials were cytotoxic (Kruskal-Wallis, P < 0.05) in a similar level to latex (P > 0.05). For intra-groups analysis, SB presented the lowest cytotoxicity (P < 0.01), while there was no statistical difference between PBNT and XENO (P > 0.05). MTT assay confirmed the cytotoxicity of the tested adhesives. Conclusion: Considering the limits of this work, all adhesives tested were as cytotoxic as latex.
