摘　　要：目的用纸片扩散法检测不同根管冲洗液对多种根管内常见菌株的抑菌圈,比较其体外抑菌能力。方法固体培养基上涂布菌悬液,放无菌滤纸片,纸片上滴加0.005mL试验液体或蒸馏水作阴性对照。适宜条件培养后观察并测定抑菌圈大小。结果BioPure MTAD对多种试验菌株的抑菌圈最大,而质量分数为1.3%的次氯酸钠对多种试验菌株的抑菌圈最小,两者间差异具有统计学意义(P<0.05)。结论在纸片扩散法中,BioPure MTAD对多种试验菌株均显示了良好的抑菌性能。Objective To compare the bacteriostasis efficacy of different irrigant to several common strain in root canal by slip diffusion method. Methods Bacterium suspension was spreaded on solid medium. Asepsis filter paper slips that contain 0.005 mL different irrigant or distilled water were placed. Specimens were cultured to determine the size of bacteriostasis-collares. Results BioPure MTAD and 1.3% sodium hypochlorite showed the maximum and minimum of bacteriostasis-collare on all strains, respectively （P〈0.05）. Conclusion The excellent bacteriostasis efficacy of BioPure MTAD to experiment strain was showed by slip diffusion method.
