Abstract

Aim: The aim of this study was to compare the canal transportation and centering ability of four rotary endodontic file systems using cone-beam computed tomography (CBCT).

Methodology: This was an in vitro study where 40 extracted single-rooted single canal human premolar teeth were used. CBCT scans of all the teeth were taken before instrumentation and were randomly divided into four groups, with 10 samples in each; Group I-Protaper Next (PN), Group II-Protaper Gold (PG), Group III-Neo Endo Flex (NE), and Group IV-Gen Endo (GE). After cleaning and shaping, the canals with respective file systems postinstrumentation scans were performed, and the two scans were compared to determine canal transportation and centering ability at 3, 6, and 9 mm, from the apex.

Results: Statistical analysis was performed using the Kruskal-Wallis test where the results showed no statistically significant difference among the tested groups in canal transportation and centering ability at the coronal, middle, and cervical third (P > 0.05).

Conclusion: Under the conditions of the in vitro study PN, PG, NE, and GE file systems exhibited comparable behavior in terms of canal transportation and centering ability, observational data suggested that Group 1 (PN) and Group 4 (GE) demonstrated superior centering ability and reduced canal transportation.

四种旋转根管文件系统的比较研究：使用锥形束计算机断层扫描评估根管运输和定心能力。

目的：本研究的目的是利用锥形束计算机断层扫描（CBCT）比较四种旋转根管锉系统的根管运输和对中能力。方法：这是一项体外研究，使用40颗拔出的单根单管人类前磨牙。在上牙前对所有牙齿进行CBCT扫描，随机分为四组，每组10个样本；组I-Protaper Next (PN)，组II-Protaper Gold (PG)，组III-Neo Endo Flex (NE)，组IV-Gen Endo （GE）。在清洁和塑形后，分别使用各自的文件系统进行检查后扫描，并比较两次扫描以确定距离根尖3、6和9 mm处的根管运输和定心能力。结果：采用Kruskal-Wallis检验进行统计学分析，结果显示各组在冠状、中、颈三段的根管运输及对中能力方面差异无统计学意义（P < 0.05）。结论：在体外实验条件下，PN、PG、NE和GE文件系统在根管运输和对中能力方面表现出相当的行为，观察数据表明，组1 （PN）和组4 （GE）表现出更强的对中能力和更少的根管运输。
