To achieve success in endodontic treatment, it is essential to properly perform the steps of shaping, cleansing and obturation. Determining the working length of the canal is, therefore, a process that must be precise and accurate. Electronic apex locators are a useful tool for the clinician to best perform this step of endodontic treatment. The purpose of the following umbrella review is to evaluate, through data in the literature, the degree of accuracy of apex locators. Seven systematic reviews were included in the following umbrella review. Five compare the accuracy of apex locators versus radiographic techniques, two compare different types of electronic apex locators, and two analyze the determination of working length in primary teeth. From the results obtained from the following umbrella review, albeit at low levels of evidence, the methods for determining working length using electronic apex locators and other methods, particularly using radiographic evaluation, are equally valid.
要想在牙髓治疗中取得成功，正确地进行根管预备、清洗和充填是至关重要的。因此，确定根管的工作长度是一个必须精确和准确的过程。电子根尖定位仪是临床医生在牙髓治疗中完成这一步的有用工具。本综述的目的是通过文献中的数据评估电子根尖定位仪的准确性。共纳入了 7 项系统评价。其中 5 项比较了电子根尖定位仪与放射技术的准确性，2 项比较了不同类型的电子根尖定位仪，2 项分析了在恒牙中确定工作长度的方法。从本次综述中获得的结果虽然证据水平较低，但使用电子根尖定位仪和其他方法（特别是使用放射学评价）确定工作长度的方法同样有效。
