Abstract

Background: Cleaning and shaping represent a vital step in the endodontic procedure. In routine endodontic therapy, the fracture of nickel-titanium (NiTi) instruments is a procedural problem creating a major obstacle to therapy.

Aim: This study examines the life span of one Neoendo Flex and ProTaper Next (PTN) rotary file using reciprocating motion and compares the time required by both file systems for canal preparation.

Materials and methods: One hundred maxillary permanent central incisors were selected. In that, fifty teeth are utilized in a reciprocating motion (RM) with the PTN file (n = 25) and Neoendo Flex file (n = 25). To check fractured resistance and the overall root canal preparation time, fifty more teeth are employed in continuous motion (CM) with canals prepared using PTN (n = 25) and Neoendo Flex (n = 25). All canals are prepared following the sequence of respective files. Later, the fracture mechanism of the files was inspected using a scanning electron microscope.

Results: In an RM motion, both PTN and Neoendo Flex files can be used in a minimum of 25 canals in single-rooted teeth. Statistical analysis using the Mann-Whitney U-test showed no significant difference in total time taken by PTN and Neoendo Flex in both motions.

Conclusion: Within the limitation of this study, the RM was found to be better than CM with less incidence of instrument fracture.

Neoendo Flex和ProTaper Next旋转锉的使用寿命，可在单根牙齿中进行往复运动。

背景：清洁和整形是根管治疗过程中至关重要的一步。在常规牙髓治疗中，镍钛（NiTi）器械的骨折是一个程序性问题，是治疗的主要障碍。目的：本研究考察了一种使用往复运动的Neoendo Flex和ProTaper Next（PTN）旋转锉的使用寿命，并比较了两种锉系统进行管预备所需的时间。材料与方法：选取100颗上颌恒中切牙。其中，在具有PTN锉刀（n=25）和Neoendo-Flex锉刀（n=25）的往复运动（RM）中使用50个齿。为了检查断裂阻力和整个根管预备时间，再使用50颗牙齿进行连续运动（CM），使用PTN（n=25）和Neoendo-Flex（n=25%）预备根管。所有水渠均按照各自文件的顺序进行准备。随后，使用扫描电子显微镜检查了锉刀的断裂机制。结果：在RM运动中，PTN和Neoendo-Flex锉都可以在单根牙齿的至少25个根管中使用。使用Mann-Whitney U型检验的统计分析显示，PTN和Neoendo-Flex在两种运动中花费的总时间没有显著差异。结论：在本研究的范围内，RM优于CM，器械骨折发生率较低。
