Accurate working length determination is essential for successful root canal therapy. This study compares the accuracy of two electronic apex locators-e-Magic Finder (EMF)-100 and WOODPEX I-with digital radiovisiography (RVG; Suni Ray) in determining root canal working length.
To evaluate and compare the accuracy of EMF-100 and WOODPEX I apex locators with RVG in determining the working length of root canals.
This was an , comparative observational study conducted in a clinical dental setting. The study included 30 patients (aged ≥15 years) requiring endodontic therapy on 45 mature permanent teeth. The aim was to evaluate and compare the accuracy of two electronic apex locators-EMF-100 and WOODPEX I-with digital radiovisiography (Suni Ray) in determining working length.
A total of 45 teeth from 30 patients (aged ≥15 years) requiring endodontic treatment were included. After obtaining consent and recording medical history, preoperative RVG images were taken using the paralleling technique. Working length was measured using three methods: EMF-100 apex locator (Group I), WOODPEX I (Group II), and RVG (Group III).
Paired -test and Chi-square test.
Both apex locators demonstrated clinically acceptable accuracy. EMF-100 showed slightly better agreement with RVG than WOODPEX I.
Both EMF-100 and WOODPEX I are effective for working length determination, with EMF-100 exhibiting slightly higher accuracy.
准确确定工作长度对于成功进行根管治疗至关重要。本研究比较了两种电子根尖定位仪——e-Magic Finder（EMF）-100和WOODPEX I与数字放射成像（RVG；Suni Ray）在确定根管工作长度方面的准确性。
评估并比较EMF-100和WOODPEX I根尖定位仪与RVG在确定根管工作长度方面的准确性。
这是一项在临床牙科环境中进行的比较性观察研究。该研究纳入了30名（年龄≥15岁）需要对45颗成熟恒牙进行牙髓治疗的患者。目的是评估并比较两种电子根尖定位仪——EMF-100和WOODPEX I与数字放射成像（Suni Ray）在确定工作长度方面的准确性。
共纳入了30名（年龄≥15岁）需要进行牙髓治疗的患者的45颗牙齿。在获得同意并记录病史后，使用平行投照技术拍摄术前RVG图像。使用三种方法测量工作长度：EMF-100根尖定位仪（第一组）、WOODPEX I（第二组）和RVG（第三组）。
配对t检验和卡方检验。
两种根尖定位仪均显示出临床可接受的准确性。EMF-100与RVG的一致性略优于WOODPEX I。
EMF-100和WOODPEX I在确定工作长度方面均有效，其中EMF-100的准确性略高。
