Abstract

Introduction: Rotary systems have made significant advances to improve their root canal preparation efficacy. These instruments can properly preserve the root canal anatomy and morphology. The present in vitro study aimed to compare canal transportation and centering ability of RaCe and Af f-one systems using cone-beam computed tomography.

Materials and methods: Thirty-six mandibular molars were included. The samples were randomly assigned to two groups (n=18): group 1, RaCe, and group 2, Af f-one. Canal preparation was conducted using the respective files according to the manufacturers' instructions. The cone-beam computed tomographic scanning of the samples was performed before and after preparation. The data were analyzed by using two-way ANOVA.

Results: In both the RaCe and Af f-one rotary systems, canal centrality and transportation were similar at coronal, middle, and apical cross-sections. In addition, canal transportation and centrality were identical in the RaCe and Af f-one rotary files (P<0.05).

Conclusion: The two studied rotary systems did not exhibit significant differences in root canal transportation and preservation of root canal centrality in the apical, middle, and coronal thirds.

通过锥形束计算机断层扫描评估 RaCe 和 Af f-one 系统的管道输送和定心能力：体外研究

简介：旋转系统在提高根管预备功效方面取得了重大进展。这些器械可以适当保留根管的解剖和形态。本体外研究旨在使用锥形束计算机断层扫描比较 RaCe 和 Af f-one 系统的根管运输和定心能力：研究对象包括 36 颗下颌磨牙。这些样本被随机分配到两组（n=18）：第一组为 RaCe，第二组为 Af f-one。根据制造商的说明使用相应的锉进行窝洞预备。在制备前后对样本进行锥形束计算机断层扫描。数据采用双因素方差分析：结果：在 RaCe 和 Af f-one 旋转系统中，冠状切面、中间切面和根尖切面的牙槽骨中心度和运输情况相似。此外，RaCe 和 Af f-one 旋转锉的牙槽骨运输和中心度也相同（PC结论：所研究的两种旋转系统在根尖、中部和冠状切面的根管运输和根管中心度保持方面没有明显差异。

期刊介绍： The Iranian Endodontic Journal (IEJ) is an international peer-reviewed biomedical publication, the aim of which is to provide a scientific medium of communication for researchers throughout the globe. IEJ aims to publish the highest quality articles, both clinical and scientific, on all aspects of Endodontics. The journal is an official Journal of the Iranian Center for Endodontic Research (ICER) and the Iranian Association of Endodontists (IAE). The Journal welcomes articles related to the scientific or applied aspects of endodontics e.g. original researches, systematic reviews, meta-analyses, review articles, clinical trials, case series/reports, hypotheses, letters to the editor, etc. From the beginning (i.e. since 2006), the IEJ was the first open access endodontic journal in the world, which gave readers free and instant access to published articles and enabling them faster discovery of the latest endodontic research.
