[The cytotoxicity of Sne-Pack periodontal dressing and scanning electron microscopic study]

We prepare a non-eugenol periodontal dressing Sne-pack(Sp),then investigated the effects of cess cytotxicity and observed the surface of materials on scanning electron of materials on scanning electron microscopy.The comparison results with Coe-pack (Cp) and zinc oxide-eugenol(Ce)showed that three materials have inconsiderable toxic effect on L-929 cell,the Sp and Cp dressing are smoother than Ce.
