Abstract

INTRODUCTION: Scientometric analyses outline the research output in a field and, therefore, help researchers and funding agencies to focus more on underinvestigated areas and make more efficient decisions related to public health. The aim of this study was METHODS: Electronic searches were done in MEDLINE and Scopus databases using specified search criteria. All articles related to the field of regenerative endodontics until December 2017 were included. The total number of publication/year and the yearly growth rate of publications were calculated. The following data were extracted and analyzed: authors, country of origin, journal, number of citations, study design, and level of evidence (LOE). The visualization maps for authorship/coauthorship, citations, and country of origin of articles were prepared and analyzed. RESULTS: A total of 694 articles were included. The average yearly growth for publications was 40.4% between 2007 and 2017. The highest number of articles were ex vivo/in vitro (n = 342, 49.27%). The distribution of articles based on LOE was as follows: LOE 1, 8.34%; LOE 2, 6.00%; LOE 3, 0.66%; LOE 4, 11.67%; and LOE 5, 73.33%. Collectively, 1820 authors contributed to the publications included in this study: 1001 authors within 40 collaborating clusters and 819 authors within 149 noncollaborating clusters. The United Sates was the lead country regarding the number of publications, citations, and international collaborations. The Journal of Endodontics published the highest number of articles. CONCLUSIONS: The total number of publications in the field of regenerative endodontics shows exponential growth in the past decade. However, the proportion of articles with LOE 1 is low. The research groups around the globe are encouraged to focus their collaborative efforts on higher-quality and clinically oriented research.

摘要

简介:科学计量学分析概述了一个领域的研究产出,因此有助于研究人员和资助机构更加关注研究不足的领域,并就公共卫生做出更有效的决策。本研究的目的是:

方法:使用特定的搜索标准在 MEDLINE 和 Scopus 数据库中进行电子搜索。纳入所有与再生牙髓学领域相关的文章,直至 2017 年 12 月。计算出版物/年总数和出版物年增长率。提取和分析以下数据:作者、原籍国、期刊、引用次数、研究设计和证据水平(LOE)。准备和分析作者/合著者、引文和文章原籍国的可视化地图。

结果:共纳入 694 篇文章。2007 年至 2017 年间,出版物的年增长率平均为 40.4%。体外/体内文章数量最多(n=342,49.27%)。基于 LOE 的文章分布如下:LOE 1,8.34%;LOE 2,6.00%;LOE 3,0.66%;LOE 4,11.67%;LOE 5,73.33%。共有 1820 位作者参与了本研究纳入的出版物:40 个合作集群中的 1001 位作者和 149 个非合作集群中的 819 位作者。美国在出版物数量、引用次数和国际合作方面处于领先地位。《牙髓病学杂志》发表的文章数量最多。

结论:过去十年,再生牙髓学领域的出版物总数呈指数级增长。然而,LOE 1 文章的比例较低。鼓励全球研究小组将合作努力集中在更高质量和临床导向的研究上。
