This study investigated the presence of co-authorship from Brazil in articles published in top-tier dental journals and analyzed the influence of international collaboration, article type (original research or review), and funding on citation rates. Articles published between 2015 and 2017 in 38 selected journals from 14 dental subareas were screened in Scopus. Bibliographic information, citation counts, and funding details were recorded for all articles (N=15619). Collaboration with other top-10 publishing countries in dentistry was registered. Annual citations averages (ACA) were calculated. A linear regression model assessed differences in ACA between subareas. Multilevel linear regression models evaluated the influence of article type, funding, and presence of international collaboration in ACA. Brazil was a frequent co-author of articles published in the period (top 3: USA=25.5%; Brazil=13.8%; Germany=9.2%) and the country with most publications in two subareas. The subjects with the biggest share of Brazil are Operative Dentistry/Cariology, Dental Materials, and Endodontics. Brazil was second in total citations, but fifth in citation averages per article. From the total of 2155 articles co-authored by Brazil, 74.8% had no co-authorship from other top-10 publishing countries. USA (17.8%), Italy (4.2%), and UK (3.2%) were the main co-author countries, but the main collaboration country varied between subjects. Implantology and Dental Materials were the subjects with most international co-authorship. Review articles and articles with international collaboration were associated with increased citation rates, whereas the presence of study funding did not influence the citations.
本研究调查了顶级牙科期刊发表文章中来自巴西的共同作者情况，并分析了国际合作、文章类型（原创研究或综述）以及资金资助对引用率的影响。在Scopus中筛选了2015年至2017年期间在14个牙科领域的38种选定期刊上发表的文章。记录了所有文章（N = 15619）的文献信息、引用次数和资金资助细节。记录了与牙科领域其他排名前十的出版国家的合作情况。计算了年度平均引用次数（ACA）。线性回归模型评估了各领域之间ACA的差异。多级线性回归模型评估了文章类型、资金资助以及国际合作在ACA中的影响。巴西是该时期发表文章的常见共同作者（排名前三：美国 = 25.5%；巴西 = 13.8%；德国 = 9.2%），并且在两个领域中发表文章数量最多。巴西参与度最高的主题是口腔手术学/龋病学、牙科材料和牙髓病学。巴西的总引用次数排名第二，但每篇文章的平均引用次数排名第五。在巴西共同撰写的2155篇文章中，74.8%没有来自其他排名前十的出版国家的共同作者。美国（17.8%）、意大利（4.2%）和英国（3.2%）是主要的共同作者国家，但主要合作国家因主题而异。种植牙学和牙科材料是国际共同作者最多的主题。综述文章和有国际合作的文章与引用率增加相关，而研究资金的存在并未影响引用率。
