The objective of this study was to evaluate the antibacterial efficacy of irrigating solutions and their combinations against Enterococcus faecalis.
One hundred ten single-rooted human teeth were inoculated with E. faecalis and incubated for 21 days. Teeth were divided according to the irrigant: Group I (GI), 2.5% sodium hypochlorite solution (NaOCl); GII, 2.5% NaOCl + 10% citric acid; GIII, 2.5% NaOCl + apple cider vinegar; GIV, apple cider vinegar; GV, 2% chlorhexidine solution; GVI, 1% peracetic acid; GVII, saline solution. Microbiological samples were taken after root canal preparation and 7 days later. Data were submitted to ANOVA (5%).
All solutions promoted reduction of E. faecalis after instrumentation, but bacterial counts were higher in the final sample. GI, GV, and GVI had lower bacterial counts than the other groups.
The irrigating solutions may present activity but do not eradicate E. faecalis in the root canal system.
本研究的目的是评估冲洗液及其组合对粪肠球菌的抗菌效果。
110颗单根人牙接种粪肠球菌并培养21天。根据冲洗剂将牙齿分组：第一组（GI），2.5%次氯酸钠溶液（NaOCl）；第二组（GII），2.5% NaOCl + 10%柠檬酸；第三组（GIII），2.5% NaOCl + 苹果醋；第四组（GIV），苹果醋；第五组（GV），2%氯己定溶液；第六组（GVI），1%过氧乙酸；第七组（GVII），生理盐水。在根管预备后和7天后采集微生物样本。数据进行方差分析（5%）。
所有溶液在器械操作后均促进了粪肠球菌数量的减少，但最终样本中的细菌计数更高。GI、GV和GVI组的细菌计数低于其他组。
冲洗液可能具有活性，但不能根除根管系统中的粪肠球菌。
