INTRODUCTION
The present investigation evaluated the ability of a new passive sonic irrigation (sonic group) system (EndoActivator) to eliminate cultivable bacteria from root canals in vivo and compared it with that of standard syringe irrigation (control group).
METHODS
Data were obtained by using bacteriologic sampling of root canals treated by endodontic residents. Sampling results from 1 session of treatment were then compared with results obtained after intervisit calcium hydroxide disinfection and a second session of treatment.
RESULTS
There was no significant difference in the ability of sonic group and control group to eliminate cultivable bacteria from root canals (P > .05). A second session and intervisit calcium hydroxide disinfection were able to eliminate cultivable bacteria from significantly more teeth than a single session of treatment (P < .05).
CONCLUSIONS
These in vivo results strengthen the case for a multi-visit approach to the treatment of apical periodontitis.
简介
本研究评估了一种新的被动声流冲洗（声流组）系统（EndoActivator）清除根管内可培养细菌的能力，并与标准注射器冲洗（对照组）进行了比较。
方法
通过对接受牙髓病学治疗的居民进行根管细菌学取样获得数据。然后将一次治疗的采样结果与在就诊间氢氧化钙消毒和第二次治疗后的结果进行比较。
结果
声流组和对照组从根管中清除可培养细菌的能力没有显著差异（P＞.05）。与单次治疗相比，第二次治疗和就诊间氢氧化钙消毒能够更有效地清除更多牙齿中的可培养细菌（P＜.05）。
结论
这些体内结果支持采用多访视方法治疗根尖周炎。
