To perform a bibliometric analysis on the top-cited articles over the last three decades from 1989 to 2018, using a longitudinal set-up, in order to analyse how articles' features have evolved over time.
A sample of 312 articles divided into three subgroups of 104 top-cited articles for each decade were included. The h-index value was used to determine the sample size.
The articles were identified through a search in the category "dentistry oral surgery and medicine" of the Web of Science database. The information relative to the articles was collected. Descriptive statistics was used to describe the articles and the journals; selected parameters were analysed with the Kruskal-Wallis and the Mann-Whitney U test at the 0.05 level of significance.
The top-cited articles were published mainly by orthodontic journals. Along the last two decades, the scientific contribution of Asian and South American countries rose significantly. The trending topics varied in each decade. Skeletal anchorage-related articles dominated the production of the decade 1999-2008 while new technologies as CBCT displayed a higher prevalence in the last decade, where new topics such as corticotomy-assisted orthodontics started to appear. The number of multi-authored articles increased while the articles from no university institutions decreased.
The publications in the three studied decades were significantly different in terms of numbers and characteristics. A longitudinal set-up allows to study the evolution of the scientific production and how the area of interest has developed over time.
使用纵向设置对 1989 年至 2018 年过去三十年的高引用文章进行文献计量分析，以分析文章特征随时间的演变。
纳入了一个由 312 篇文章组成的样本，分为三个 104 篇高引用文章的子组，每个十年一组。使用 h 指数值来确定样本量。
通过在 Web of Science 数据库的“牙科口腔外科和医学”类别中进行搜索，确定了这些文章。收集了与文章相关的信息。使用描述性统计数据来描述文章和期刊；在 0.05 水平的显著性下，使用 Kruskal-Wallis 和 Mann-Whitney U 检验分析选定参数。
高引用文章主要发表在正畸期刊上。在过去的二十年中，亚洲和南美洲国家的科学贡献显著增加。每个十年的热门话题都有所不同。1999-2008 年，骨骼锚定相关文章占据主导地位，而在过去十年中，新技术如 CBCT 更为流行，新的话题如皮质切开辅助正畸开始出现。多作者文章的数量增加，而无大学机构的文章数量减少。
在过去的三个十年中，出版物在数量和特征方面存在显著差异。纵向设置允许研究科学产出的演变以及该领域如何随时间发展。
