常规根管治疗器械治疗疑难根管的疗效分析

Clinical efficacy analysis on application of conventional instruments in difficult root canal treatment

[目的]探讨应用常规器械对疑难根管进行根管治疗的临床疗效。[方法]收集临床10例疑难根管患牙。拍术前片,了解牙根及根管形态,估计操作难度。制定相应治疗方案,采用GG钻,K锉,ProTaper手用锉在同一患牙上联合预备疑难根管,观察疗效。[结果]10例患牙根管均疏通成功,根管预备过程中无根管偏移、根尖阻塞、台阶等并发症发生,X线片显示根管形态良好,根管充填完善呈连续锥度。术后两周随诊观察均无不良反应。[结论]对于疑难根管可以通过多种常规器械联合应用完成根管预备,可达到理想治疗效果。

[Objective] This is to explore the therapeutic effects for the difficult root canal treatment using conventional instruments.[Methods] Ten clinical cases with difficult root canals were collected.Referred from the X-ray,the morphology of root and root canals were understood,and the difficulty of operation was estimated.The corresponding therapeutic schemes were made.The difficult root canals were prepared by GG drill combined with hand ProTaper file and K filing on the same teeth.The patients were followed for two weeks and the therapeutic effects were observed.[Results] Root canals in 10 teeth were negotiated.There were no complications such as canal transportation,root tip or steps.X-ray showed the root canal shape was good,and the filling was perfect with continuous taper.[Conclusions] Using combined application of several conventional instruments,the desired therapeutic effects can be achieved in difficult root canal treatment.
