Abstract：AIM:To observe the antimicrobial effect of Vibringe sonic root canal irrigator combined with so-dium hypochlorite on Enterococcus faecalis(E.faecalis) in root canal. METHODS:75 single-rooted human teeth in-fected with E.faecalis were randomly divided into 3 groups (n=25). From each group,5 samples were observed by scanning electron microscope,10 teeth were randomly selected and the dentin bacterial counts at different depths(0~100,100~200,200~300 μm) were measured and served as baseline data.The other 10 samples in each group were respectively treated with the Vibringe+52.5 g/L sodium hypochlorite (group A), syringe+52.5 g/L sodium hypo-chlorite (group B) and syringe + normal saline(group C). At last,the samples of root canal wall at different depths inside dentin tubules were collected. The bacterial reduction rates of each treatment were compared among groups and analyzed by one-way ANOVA.RESULTS:On the surface and at different depths inside dentin tubules,the bacteria clearance was more than 99% in group A and B,significantly greater than that in group C(P<0.05); group A vs group B,P>0.05. CONCLUSION:Vibringe root canal irrigator+52.5 g/L sodium hypochlorite can effectively e-liminate E.faecalis on the surface and at different depths inside dentin tubules,but it does not show obvious advantages to traditional syringe irrigation of 52.5g/L sodium hypochlorite.
