体外评估洗必泰根管冲洗即时和7d后对粪肠球菌作用

目的体外实验对比2%洗必泰和其他2种冲洗液对粪肠球菌即时和7d的抗菌能力。方法45个单根管牙根预备,灭菌使用粪肠球菌进行感染。随机分为三组,使用不同冲洗液,取即时和术后七天的微生物样本,计数细菌菌落。结果SPSS统计学分析,2%洗必泰和2.5%次氯酸钠对粪肠球菌有效,7d后洗必泰组呈现更低的CFU计数。结论2%洗必泰是有效的根管冲洗药物,有持续的抗菌能力。

Objective It was to compare the immediately and 7 days after irrigation antibacterial efficacy of 2% CHX against Enterococcus faecalis with 2.5% NaOCl and 0.9% saline solution. Method 45 single root canals were prepared , autoclaved and infected by Enterococcus faecalis and were divided randomly in to three groups. Different irrigants were used , the immediately and 7 days after irrigation microbiological samples were taken and counted the CFU. Results The 2% CHX and 2.5% NaOCl significantly reduced E, faecalis and 2%CHX had lower CFU count 7 days after irrigation. Conclusion The 2%CHX was effective and substantive as endodontic irrigants against Enterococcus faecalis even after 7 days.
