ABSTRACT
Objective:
To evaluate the toxic effect of 3 different gingival retraction cords.Methods:
DMEMextraction of DL-adren-aline HCl,aluminium sulphate and non-drug retraction cords with the extraction time of 5,10,15 and 30 min were respectively pre-pared and were used to culture human gingival fibroblasts(HGFs)in vitro respectively.Cell proliferation was tested by MTT assay. Cell apoptosis was examined by Annexin/PI method.Results:
The 3 gingival retraction cord extractions inhibited the roliferation,pro-moted the apoptosis of HGFs(P <0.05),the effects were related to the extraction time.Conclusion:
The 3 retraction cords have time-dependant cytotoxity.
