The aim of the present study was to analyze two distinct biomedical electronic databases for the 100 most-cited articles in the field of periodontology.
Two electronic databases (Scopus [SCO] and Web of Science [WOS]) were used to retrieve lists of the 100 most-cited articles using appropriately-chosen keywords. The correlation between the number of citations and age of publication was evaluated statistically.
Sixty-three papers could be found in both lists. The mean number of citations in SCO was 476.7 ± 361.9 and 371.2 ± 249.7 in WOS. The mean age of publication in the SCO list was 21.4 ± 9.4 years and 18.6 ± 6.5 years in the WOS list. No correlation was found between age of publication and number of citations for both databases.
There is a lack of evidence of the correlation between age of publication and number of citations. The concordance between the two databases that were reviewed was relatively significant, even though the rankings of the most-cited articles are dependent on the number of journals covered by one database. The actual value of the number of citations to measure the quality of one article should be carefully evaluated.
本研究旨在分析两个不同的生物医学电子数据库中牙周病学领域被引用次数最多的100篇文章。
使用两个电子数据库（Scopus [SCO]和科学网[WOS]），通过适当选择的关键词检索被引用次数最多的100篇文章列表。对引用次数与发表年份之间的相关性进行统计学评估。
两个列表中均可找到63篇论文。SCO中的平均引用次数为476.7±361.9，WOS中的平均引用次数为371.2±249.7。SCO列表中的平均发表年份为21.4±9.4年，WOS列表中的平均发表年份为18.6±6.5年。两个数据库的发表年份与引用次数之间均未发现相关性。
缺乏发表年份与引用次数之间相关性的证据。尽管被引用次数最多的文章排名取决于一个数据库所涵盖的期刊数量，但所审查的两个数据库之间的一致性相对较高。应仔细评估引用次数衡量一篇文章质量的实际价值。
