The Brazilian Dental Journal (BDJ) was officially launched in 1990, stimulated by the courage and boldness of researchers dedicated to teaching and research in dentistry. The journal was conceived in a worldwide coverage and universal language to allow publication of the results of Brazilian studies, which otherwise would not be accessible to the scientific dental community. In the year we celebrate the thirtieth anniversary of BDJ, this article presents a brief overview of Brazilian dental research and a bibliometric analysis of the articles published in this journal as a contribution to our readers and fellow researchers. The purpose was to identify the mot frequent categories of study, the most published areas of dentistry and BDJ's top 50 most-cited articles in the Scopus and Google Scholar databases. A search was performed on all BDJ online issues published from 1990 to 2019. In this period, BDJ published 1,710 articles. Based on their distribution by category of study, 557 articles were in the basic research/dental materials area, 527 in the basic research/biology area and 280 in the clinical research area. Eight articles were cited more than 100 times in the Scopus database and 266 times in the Google Scholar database. Endodontics was the most published area. This overview of BDJ production over those 30 years allows establishing a profile of the characteristics, impact and trends of the published studies, as well as the journal's contribution to the top 50 most-cited articles in the Scopus and Google Scholar databases.
《巴西牙科杂志》（BDJ）于1990年正式创刊，这得益于致力于牙科教学与研究的科研人员的勇气与魄力。该杂志旨在面向全球发行并使用通用语言，以便发表巴西的研究成果，否则这些成果将无法为牙科科学界所获取。在我们庆祝BDJ创刊三十周年之际，本文简要概述了巴西牙科研究情况，并对该杂志发表的文章进行了文献计量分析，以飨读者及同行研究人员。目的是确定最常见的研究类别、牙科领域发表最多的领域以及BDJ在Scopus和谷歌学术数据库中被引用次数最多的50篇文章。对1990年至2019年期间BDJ在线发表的所有期刊进行了检索。在此期间，BDJ共发表了1710篇文章。根据研究类别的分布情况，557篇文章属于基础研究/牙科材料领域，527篇属于基础研究/生物学领域，280篇属于临床研究领域。有8篇文章在Scopus数据库中被引用超过100次，在谷歌学术数据库中被引用266次。牙髓病学是发表文章最多的领域。对BDJ这30年的出版情况进行的概述有助于了解已发表研究的特点、影响力和趋势，以及该杂志对Scopus和谷歌学术数据库中被引用次数最多的50篇文章的贡献。
