It is important to evaluate the characteristics of the most cited articles in any specialty. The number of citations may be a proxy for clinical and research activity. The objectives of the present methodological study were (1) to report the characteristics of the 300 most cited articles in periodontology and (2) to explore the association of these characteristics with the number of citations.
We searched in the Web of Science database for the 300 most cited articles published in periodontology on June 15, 2015. We described characteristics of the articles such as type of study, type of scientific journal, topic reported, year of publication, affiliation of the first author of the article, and impact factor. Linear regression analysis was used to investigate associations of these variables with the number of citations.
The search retrieved approximately 155,356 publications; out of the studies that met the eligibility criteria, the 300 most cited were included for analysis. Comprising more than 50 % of the included articles, basic biology and the detection of bacteria were the most prevalent topics. Narrative reviews were the most frequent type of article (27 % of the sample). Regression analysis demonstrated that some characteristics, for example "narrative reviews," are more prone to be cited than others.
We conclude that scientific evolution in periodontology has been based more on narrative reviews than on reproducible systematic reviews.
Future research is encouraged to elucidate the extent to which scientific progress is improved through systematic compared with narrative reviews.
评估任何专业中被引用最多的文章的特点都很重要。引用次数可能是临床和研究活动的代表。本方法学研究的目的是：（1）报告牙周病学中被引用次数最多的 300 篇文章的特征；（2）探讨这些特征与引用次数之间的关联。
我们在 Web of Science 数据库中搜索了 2015 年 6 月 15 日发表的牙周病学领域被引用次数最多的 300 篇文章。我们描述了文章的特征，如研究类型、科学期刊类型、报道的主题、发表年份、文章第一作者的所属机构以及影响因子。线性回归分析用于研究这些变量与引用次数之间的关联。
搜索共检索到约 155356 篇出版物；符合入选标准的研究中，有 300 篇被纳入分析。基础生物学和细菌检测是最常见的主题，占纳入文章的 50%以上。叙述性评论是最常见的文章类型（占样本的 27%）。回归分析表明，一些特征，如“叙述性评论”，比其他特征更容易被引用。
我们得出的结论是，牙周病学的科学发展更多地基于叙述性综述，而不是可复制的系统综述。
鼓励未来的研究阐明通过系统综述与叙述性综述相比，科学进展在多大程度上得到改善。
