Abstract：
BACKGROUND: This bibliometric review analyzed the research trends and main characteristics of articles related to Electronic Apex Locators (EALs).
METHODS: The search was conducted in November 2023 on the Web of Science Core Collection. Narrative and systematic reviews, observational and intervention studies, laboratory, and clinical studies were included. Two researchers selected the articles and extracted the number of citations, year of publication, journal, study design, theme, country, continent, institutions, author, and keywords. Collaborative networks were generated using the VOSviewer software. The relationship between data were determined by Spearman\'s correlation.
RESULTS: The search resulted in 374 articles, of which 294 were included. Most cited article had 175 citations. The most prevalent journal was the Journal of Endodontics (n = 84). The predominant study design was the laboratory-based (n = 223). The predominant theme was the EALs accuracy (n = 175). Piasecki L was the author with the highest number of articles (n = 11). Only 8.16% of the studies were conducted in deciduous teeth. The country with the most studies was Brazil (n = 46). Asia (n = 107) was the continent with the highest number of publications. There was a weak positive correlation between the number of citations and impact factor (rho = .294), and a strong negative correlation between citations and year of publication (rho = -.710).
CONCLUSIONS: The majority of articles were laboratory-based studies conducted on permanent teeth, focusing on the accuracy of EALs. Future studies should prioritize research on deciduous teeth, systematic reviews, and, notably, clinical trials.

摘要：
背景：这篇文献计量学综述分析了与电子顶点定位器（EAL）相关的文章的研究趋势和主要特征。
方法：搜索于2023年11月在WebofScienceCoreCollection上进行。叙事和系统审查，观察和干预研究，包括实验室和临床研究。两名研究人员选择了这些文章并提取了引用次数，出版年份,journal,研究设计，主题,国家,大陆,机构,作者,和关键词。使用VOSviewer软件生成协作网络。数据之间的关系由Spearman相关性确定。
结果：搜索结果为374篇文章，其中包括294个。引用最多的文章有175次引用。最流行的杂志是牙髓学杂志（n=84）。主要的研究设计是基于实验室的(n=223)。主要主题是EAL的准确性（n=175）。PiaseckiL是文章数量最多的作者（n=11）。只有8.16％的研究是在乳牙中进行的。研究最多的国家是巴西（n=46）。亚洲（n=107）是出版物数量最多的大陆。引用次数与影响因子之间存在弱正相关(rho=.294)，引文和出版年份之间存在很强的负相关(rho=-.710)。
结论：大多数文章是对恒牙进行的实验室研究，专注于EALs的准确性。未来的研究应该优先研究乳牙，系统评价,and,特别是,临床试验。
