Root canal therapy is the primary treatment method for pulpal and periapical diseases. Various advanced endodontic instruments for mechanical preparation have been marketed. The emergence of nickel-titanium rotary instruments has greatly improved the efficiency of root canal preparation. New demands have been put forward for nickel-titanium rotary instruments as a result of the deepening of clinicians' awareness of root canal anatomy system as well as the purpose and prognosis of root canal treatment. These clinical-oriented demands accelerate instrument reform and innovation. This work presents new marketed nickel-titanium systems and discusses the advantages and limitations of these systems and how they perform in terms of the efficiency and outcome of root canal preparation.
根管治疗是牙髓和根尖周疾病的主要治疗方法。各种先进的根管机械预备器械已经上市。镍钛旋转器械的出现极大地提高了根管预备的效率。随着临床医生对根管解剖系统以及根管治疗目的和预后认识的加深，对镍钛旋转器械提出了新的要求。这些以临床为导向的需求加速了器械的改革和创新。本文介绍了新上市的镍钛系统，并讨论了这些系统的优缺点以及它们在根管预备效率和效果方面的表现。
