The purpose of this review was to identify and analyze the main characteristics of the 100 most-cited papers in the field of endodontic therapy in primary teeth. A search for the most-cited articles was conducted in the Clarivate Analytics Web of Science 'Core-Collection' (WoS-CC) database up to December 2020. Papers were ranked in descending order, by number of citations, and each paper was matched with the citation count on Scopus and Google Scholar. Two independent reviewers selected the most-cited papers and analyzed it according to the number and density of citations, year and journal of publication, authors, countries and contributing institutions, study design, topic of the paper, and keywords. Spearman's correlation and Poisson regression were used to determine associations between the number of citations and study characteristics. The citation count varied from 15 to 135 (WoS-CC), 8 to 141 (Scopus), and 14 to 317 (Google Scholar). Of the 306 contributing authors, most paper contributions were from Sakai VT, Oliveira TM, and Machado MAAM (5 each). Most of the papers originated from the USA (n=21) and Brazil (n=18). Randomized trials were the most common study design (n=32), and "pulpotomy" was the most frequently used keyword (n=35). Poisson regression showed that the number of citations decreased by 1.5% each year, and increased by 9.7% for each unit of impact factor. This bibliometric analysis highlighted papers, authors, and institutions that have contributed to endodontic therapy in primary teeth. Common terms of interest in this research area was also identified, representing the first bibliometric analysis on this subject.
本文旨在确定和分析乳牙牙髓治疗领域中被引频次最高的 100 篇论文的主要特征。通过在科睿唯安 Web of Science '核心合集'（WoS-CC）数据库中进行高被引文献检索，检索时间截至 2020 年 12 月。根据被引频次降序排列论文，并在 Scopus 和 Google Scholar 上对每篇论文进行匹配，以获取其被引频次。两名独立的审查员选择了被引频次最高的论文，并根据被引频次、发表年份和期刊、作者、国家和贡献机构、研究设计、论文主题和关键词进行分析。采用 Spearman 相关分析和 Poisson 回归分析来确定被引频次与研究特征之间的关系。WoS-CC 的被引频次范围为 15-135，Scopus 为 8-141，Google Scholar 为 14-317。在 306 名贡献作者中，Sakai VT、Oliveira TM 和 Machado MAAM 的论文贡献最多（各 5 篇）。大多数论文来源于美国（n=21）和巴西（n=18）。随机对照试验是最常见的研究设计（n=32），“活髓切断术”是最常用的关键词（n=35）。Poisson 回归显示，每年被引频次减少 1.5%，每增加 1 个单位的影响因子，被引频次增加 9.7%。这项文献计量学分析突出了为乳牙牙髓治疗做出贡献的论文、作者和机构。还确定了该研究领域的共同关注术语，这是首次对此主题进行文献计量学分析。
