摘　　要：将180根感染粪肠球菌和变异链球菌的牙胶尖随机分为12组（n=15），分别用强酸性电解质水、5．25％次氯酸钠处理1min，杀菌率75．22％一79．97％，处理5min，杀菌率97．68％～99．59％；生理盐水组杀菌率3．55％～4．05％（P〈0．05）。强酸性电解水和次氯酸钠作用5min的杀菌效果优于1min（P〈0．05）。由此得出结论，强酸性电解质水作用5min就可以有效地消毒牙胶尖。The Enterococcus faecalis and Streptococcus mutaus infected gutta-percha cones （n = 180） were randomly divided into 12 groups （n = 15）. They were treated by strong acid electrolytic water （SAEW）, 5.25 % sodium hypochlorite solution （NaC10） and 0.9% normal saline （NS） for 1 min and 5 min respectively. After SAEW or 5.25% NaC10 treatment for 1 min, viable cells decreased by 75.22% - 79.97% , and after 5 min treatment, decreased by 97.68% -99.59% respectively. NS treatment decreased the viable cells by 3.55% - 4.05%. 5 rain treatment of SAEW is effective in the disinfection of gutta-percha cones.
