Bibliometric analysis is the quantitative analysis of measurable citation information of a journal. It unveils research topics, publishing trends, assess research impact, and productivity.
The purpose of this study was to conduct a bibliometric analysis to identify and analyze the top 50 most cited articles published in the (JCD).
Clarivate Analytics' Web of Science was used to search and identify the 50 most cited scientific papers of JCD. Each article was then cross-matched with Google Scholar and PubMed databases and the mean citation was derived. In addition, citation density for each article was derived to negate the age of publication factor.
Shapiro-Wilk test and Kolmogorov-Smirnov test were done to detect departures from normality. For testing and determining correlations among several variables, the Spearman rank test was performed.
The top 50 most-cited articles received a total of 6263 (Google Scholar), 323 (PubMed), and 2056 (Web of Science) citations. Major topics of interest in the top 50 most-cited articles were dental material science ( = 18) and carious and noncarious lesion management ( = 14). There was no significant association between mean citation count and time since publication (correlation coefficient = 0.273, = 0.055). However, there was a significant negative association of citation density (correlation coefficient = -0.647, < 0.01) with time since publication.
Bibliometric analysis of top-cited articles gave valuable insights into journal's research history and progress of the journal concerning dissemination of scholarly work.
文献计量分析是对期刊可测量的引用信息进行定量分析。它揭示研究主题、出版趋势、评估研究影响力和生产力。
本研究的目的是进行文献计量分析,以识别和分析发表在《牙体牙髓病学杂志》(JCD)上被引用次数最多的前50篇文章。
使用科睿唯安的Web of Science搜索并识别JCD被引用次数最多的50篇科学论文。然后将每篇文章与谷歌学术和PubMed数据库进行交叉匹配,并得出平均引用次数。此外,计算每篇文章的引用密度以消除出版年份因素的影响。
进行Shapiro-Wilk检验和Kolmogorov-Smirnov检验以检测数据是否偏离正态分布。为了检验和确定几个变量之间的相关性,进行Spearman秩检验。
被引用次数最多的前50篇文章在谷歌学术上共获得6263次引用、在PubMed上获得323次引用、在Web of Science上获得2056次引用。被引用次数最多的前50篇文章中主要关注的主题是牙科材料科学(n = 18)和龋病及非龋性病变的管理(n = 14)。平均引用次数与自发表以来的时间之间没有显著关联(相关系数 = 0.273,P = 0.055)。然而,引用密度与自发表以来的时间存在显著负相关(相关系数 = -0.647,P < 0.01)。
对高被引文章的文献计量分析为该期刊的研究历史以及该期刊在学术成果传播方面的进展提供了有价值的见解。
