Abstract

OBJECTIVES

Scientometric methods and the resulting citations have been applied to investigate the scientific performance of a nation. The present study was designed to collect the statistical information of dental articles by Iranian authors published in PubMed.

MATERIALS AND METHODS

We searched the PubMed database for dental articles of Iranian authors until June 31, 2015. All abstracts were manually reviewed in order to exclude false retrievals. The number of articles per dental subspecialties, distribution of research designs, Scopus/Google Scholar citation of each article, number of authors and affiliation of the first/corresponding author were extracted and transferred to Microsoft Excel. The data were further analyzed to illustrate the related scientometric indicators.

RESULTS

A total of 3,835 articles were retrieved according to the selection criteria. The number of PubMed-indexed publications between 2008 and 2015 showed a seven-fold increase. The majority of articles were written by four authors (24.56%). Systematic reviews and clinical trials constituted 9.20% of all publications. The number and percentage of articles with ≥4 citations from Google Scholar (n=2024; 52.78%) were higher than those from Scopus (n=1015; 26.47%). According to affiliated departments of the first authors, the top three dental subspecialties with the highest number of publications belonged to endodontics (19.82%), orthodontics (11.13%) and oral and maxillofacial surgery (10.33%). Moreover, the majority of articles originated from Shahid Beheshti- (14.47%), Tehran- (13.72%) and Mashhad- (12.28%) University of Medical Sciences.

CONCLUSIONS

Analysis of PubMed-indexed dental publications originating from Iran revealed a growing trend in the recent years.

摘要

目的

科学计量学方法及由此产生的引用情况已被用于研究一个国家的科研表现。本研究旨在收集伊朗作者发表在PubMed上的牙科文章的统计信息。

材料与方法

我们在PubMed数据库中搜索截至2015年6月31日伊朗作者的牙科文章。所有摘要均经过人工审核以排除错误检索。提取每个牙科亚专业的文章数量、研究设计分布、每篇文章的Scopus/谷歌学术引用次数、作者数量以及第一/通讯作者的所属机构，并将其转移到Microsoft Excel中。对数据进行进一步分析以说明相关的科学计量指标。

结果

根据选择标准共检索到3835篇文章。2008年至2015年期间被PubMed索引的出版物数量增长了七倍。大多数文章由四位作者撰写（24.56%）。系统评价和临床试验占所有出版物的9.20%。来自谷歌学术且被引用≥4次的文章数量（n = 2024；52.78%）和百分比高于来自Scopus的（n = 1015；26.47%）。根据第一作者的所属科室，发表文章数量最多的前三个牙科亚专业分别是牙髓病学（19.82%）、正畸学（11.13%）和口腔颌面外科学（10.33%）。此外，大多数文章来自谢赫·贝赫什提医科大学（14.47%）、德黑兰医科大学（13.72%）和马什哈德医科大学（12.28%）。
