XP-endo Finisher清除椭圆形根管细菌生物膜的效果研究
|
Abstract:
摘要 目的:比较XP-endo Finisher(XPF)和被动超声冲洗(passive ultrasonic irrigation, PUI),及两者联合应用清除椭圆形根管细菌生物膜的效果。方法:选取54颗成人离体单根管横截面为椭圆形的前磨牙,建立多菌种生物膜感染根管模型。厌氧培养4周后随机选取6颗为对照,扫描电镜(Scanning electron microscopy,SEM)确认多菌种生物膜形成。余牙应用Vortex Blue预备到40/.06后分为4个实验组(n=12),分别采用传统注射器冲洗(conventional needle irrigation,CNI)、PUI、XPF、PUI+XPF结合3%次氯酸钠溶液进行根管处理。采集样本根管尖、中、冠1/3 SEM图像,计算残余细菌生物膜面积百分比。结果:细菌清除效率由高到低依次为PUI+XPF、XPF、PUI、CNI,前两者无统计学差异(P＞0.05)。结论:XPF清除椭圆形根管生物膜的效果优于PUI和CNI,与PUI联合应用有加强效果但无显著差异
