摘要
目的:比较不同冲洗方法对微创预备后根管内氢氧化钙封药的清除效果,为临床治疗提供参考.方法:使用TruNatomy镍钛系统对32个前磨牙进行微创根管预备后,向根管内封人氢氧化钙.根据不同冲洗方法将样本随机分为4组(n=8):被动超声荡洗(PUI)组、声波荡洗(EDDY)组、XP-endofinisher(XPF)组、手用K锉(K File)组.冲洗前后拍摄CBCT,并对残余氢氧化钙进行定量计算,比较不同冲洗方法对氢氧化钙的清除效果.结果:所有冲洗技术应用后根管内均存在氢氧化钙残留,使用PUI、XPF、EDDY和K File之间存在显著差异(P＜0.05),PUI和XPF组的氢氧化钙残留量相对较少.结论:在微创预备后,使用PUI和XPF对根管内的氢氧化钙去除效果更好,但PUI的效率与XPF间无显著差异.
Abstract
AIM:To evaluate the efficiency of different irrigation methods in removal of calcium hydroxide from root canals after minimally invasive endodontics,providing a reference for clinical treatment.METHODS:A total of 32 premolars were minimally invasive prepared by TruNatomy system and filled with calcium hydroxide.The samples were randomly divided into 4 groups(n=8)according to different irrigation methods:passive ultrasonic irrigation(PUI),sonic agitation,XP-endo finisher(XPF)irrigation,and K File irrigation.The volumes of the residual calcium hydroxide were measured by CBCT before and after irrigation,to compare the removal efficiency of different irritation methods and solu-tions.RESULTS:After the application of all irrigation techniques,calcium hydroxide residues remained within the root canals,with significant differences observed between the use of PUI,XPF,EDDY,and K File(P＜0.05),where the PUI and XPF groups had relatively less calcium hydroxide residue.CONCLUSION:After minimally invasive preparation,the use of PUI and XPF is more effective in removing calcium hydroxide from the root canal,but there is no significant differ-ence in efficiency between PUI and XPF.
