Objective To evaluate the effect of electroiyzed oxidizing water( EOW) immersed disinfection on dimensional stability of alginate impressions. Methods Two kinds of alginate impressions were made from standards test mold. There were 20 impressions made with each kind of material, which were divided into 4 groups randomly. There was no-immersion in the control group, and in the rest three experimental groups the alginate expressions were immersed in EOW for 15 minutes, 20 minutes and 25 minutes respectively. Super hard gypsum was used for molding. All gypsum casts were inspected with a measuring microscope for specific line. Statistical comparisons between the experimental groups and the control group were made. Results Compared with the control group, the two experiment groups with EOW immersed disinfection for 15 minutes and 20 minutes showed no significant effect on the dimensional change of alginate impressions (P >0.05), while the group with 25 minutes exhibited significant eSecl(P <0.05). Conclusion There is no effection EOW immersed disinfection for 20 minutes on the dimensional stability of alginate impressions.
