Abstract

Background and Objective: The preparation of the root canal (i.e., cleaning and shaping) is the main step in the endodontic treatment. The nickel-titanium rotary files result in fewer errors during the preparation of curved canals. This study aimed to compare the transportation of Neolix and Reciproc rotary systems in curved canals using cone beam computed tomography (CBCT). Materials and Methods: In this experimental study, 70 extracted curved premolar teeth from patients referred to dentistry faculty were assigned into two groups (n=35). The preparation of the canals was performed by the Neolix and Reciproc rotary systems. Remaining dentin thickness, transportation, and canal-centering ratio were evaluated and compared using CBCT images before and after the instrumentation. The data were analyzed in SPSS software (version.19) through ANOVA, independent t-test, and paired t-test. Results: There was a significant difference in terms of remaining dentin thickness in three sections of 3, 5, and 7 mm from the apex, before and after the instrumentation regarding the level of mesiodistal and buccolingual. However, no significant difference was observed in terms of the transportation in three sections of 3, 5, and 7 mm from the apex in both Neolix and Reciproc systems. Conclusion: According to the results, both Neolix and Reciproc rotary systems showed high efficacy in root canal shaping. The amount of transportation in these systems during preparation of curved canals was very low leading to the protection of canal-centering ratio.
锥形束计算机断层扫描法比较弯曲根管中往复和Neolix旋转系统内的输运
背景与目的:根管预备(即清洁和塑形)是根管治疗的主要步骤。镍钛旋转锉在弯曲管的制备过程中误差较小。本研究旨在使用锥形束计算机断层扫描(CBCT)比较Neolix和往复式旋转系统在弯曲管中的传输。材料和方法:在本实验研究中,将70颗从牙科教师那里拔出的弯曲前臼齿分为两组(n=35)。运河的准备工作由Neolix和往复式旋转系统完成。使用CBCT图像评估和比较器械前后的剩余牙本质厚度、运输和管中心比率。数据在SPSS软件(19版)中通过方差分析、独立t检验和配对t检验进行分析。结果:在距离根尖3、5和7mm的三个切片中,在器械前后,就近中、颊舌水平而言,剩余牙本质厚度存在显著差异。然而,在Neolix和往复式系统中,在距离顶点3、5和7mm的三个部分的运输方面没有观察到显著差异。结论:根据结果,Neolix和往复式旋转系统在根管成形方面均显示出较高的疗效。在弯曲运河的准备过程中,这些系统中的运输量非常低,这导致了对运河中心比的保护。
