Abstract

Introduction: Endodontic instrument separation is one of the iatrogenic errors which may affect the outcome of treatment. The present in vitro study was aimed to investigate the effect of different cross-sectional designs of separated nickel–titanium (Ni-Ti) rotary files on apical microleakage. Materials and Methods: A total of 48 mandibular premolar roots were selected. The samples were randomly assigned to four experimental groups including Mtwo (n = 10), HERO Shaper (n = 10), RaCe (n = 10), and FlexMaster (n = 10) as well as positive (n = 4) and negative (n = 4) control groups. Ni-Ti rotary instruments with the same size and taper (0.06, #30) were separated in the apical region after complete cleaning and shaping, and the remaining root canal was obturated with gutta-percha and AH-26 sealer. The bacterial microleakage of each group was assessed through Enterococcus faecalis for 60 days. Survival analysis was done by SPSS 22. Results: There were no statistically significant differences between the studied groups in terms of the time of microleakage (P = 0.955). Conclusion: The separated Ni-Ti rotary instruments with different cross-sectional designs had no impact on apical microleakage.

不同分离镍钛旋转器械对根尖微漏的体外研究

根管器械分离是影响治疗效果的医源性错误之一。本研究旨在探讨不同截面设计的分离镍钛(Ni-Ti)旋转锉对根尖微渗漏的影响。材料与方法:选取48根下颌前磨牙根。将样本随机分为Mtwo (n = 10)、HERO Shaper (n = 10)、RaCe (n = 10)和FlexMaster (n = 10)四个实验组以及阳性(n = 4)和阴性(n = 4)对照组。在根尖区完全清洁定型后分离相同尺寸和锥度(0.06，#30)的Ni-Ti旋转器械，用杜仲胶和AH-26密封剂封闭剩余根管。采用粪肠球菌法观察各组细菌微渗漏情况，持续60 d。生存分析采用SPSS 22进行。结果:两组间微漏时间差异无统计学意义(P = 0.955)。结论:不同截面设计的分离镍钛旋转器械对根尖微漏无影响。

期刊介绍： Vision SEJ aims to be one of the foremost worldwide periodical on Endodontics, dedicated to the promotion of research, post-graduate training and further education in Endodontics. Mission Statement To serve as a medium for continued Endodontic education and qualitative scientific publications on clinical trials, basic science related to the biological aspects of Endodontics, basic science related to Endodontic techniques as well as dental trauma that will ultimately improve the Endodontic research and patient’s health. Scope In this journal, Endodontists, Endodontic postgraduate students and general dentists, can learn about new concepts in root canal treatment and the latest advances in techniques and instrumentation that help them keep pace with rapid changes in this field. Aims and Objectives To publish cut edge peer-review original articles, case reports, letters to the editor, editorials, review articles, commentaries, and innovations that will impact on Endodontics. To enhance exchange of ideas/information relating to Endodontics and interaction among stakeholders. To encourage networking and partnership between individuals, government and non-governmental organizations for the provision of quality health care. To advocate for training, workshops, seminars, scientific manuscript writing conferences that will advance publishing culture.
