One of the crucial steps in endodontic treatment is determining the working length (WL). There are various methods for performing this procedure, one of which is an electronic apex locator (EAL) measurement.
The aim of this study was to determine the accuracy of six EALs, i.e.. Root ZX, Root ZX Mini, Propex PiXi, Innvopex-1, Woodpex III, and Raypex 6 for WL estimation in the mandibular first molars.
The study included 180 root canals with symptomatic irreversible pulpitis, divided into six groups using different apex locators. WL determination was compared with intraoral periapical radiographs. Results were categorized as accurate, short, or long. The data were statistically analyzed.
ROOT ZX had an accuracy of 96.7%, Root ZX Mini had an accuracy of 93.3%, PiXi had an accuracy of 90.0%, Innvopex-1 had an accuracy of 90.0%, Woodpex III had an accuracy of 86.7%, and Raypex 6 had an accuracy of 83.4%, respectively. There was a statistically nonsignificant difference between groups ( < 0.05).
Newly developed apex locators, such as the Innvopex-1, have shown accuracy comparable to well-established EALs like the Root ZX. This highlights the importance of conducting more extensive, large-scale research to confirm and validate their effectiveness.
根管治疗的关键步骤之一是确定工作长度（WL）。执行此程序有多种方法，其中之一是电子根尖定位仪（EAL）测量。
本研究的目的是确定六种EAL（即Root ZX、Root ZX Mini、Propex PiXi、Innvopex - 1、Woodpex III和Raypex 6）在下颌第一磨牙中估计工作长度的准确性。
该研究纳入了180个有症状的不可逆性牙髓炎根管，使用不同的根尖定位仪将其分为六组。将工作长度的测定结果与口内根尖片进行比较。结果分为准确、短或长三类。对数据进行统计学分析。
Root ZX的准确率为96.7%，Root ZX Mini的准确率为93.3%，PiXi的准确率为90.0%，Innvopex - 1的准确率为90.0%，Woodpex III的准确率为86.7%，Raypex 6的准确率为83.4%。各组之间存在统计学上无显著差异（<0.05）。
新开发的根尖定位仪，如Innvopex - 1，已显示出与成熟的EAL（如Root ZX）相当的准确性。这突出了进行更广泛、大规模研究以确认和验证其有效性的重要性。
