To carry out a bibliometric analysis of all electronically available dental literature in Iran from 1983 to 2006, in order to study availability and examine trends.
Accessing all electronically available Iranian dental articles published in domestic journals, and comparing the results with Iranian dental articles published in Pubmed. The following data were collected from each article: name of journal, year of publication, number of authors, gender of corresponding author, academic levels of authors, main language of article, language of abstract, study environment, population studied, field of dentistry, type of article, design strategy, design of study, and analysis design.
In terms of publications in domestic journals, a total of 1,994 dental articles were electronically available, published in six different dental journals in Iran. Majority of articles, 84.5%, were original studies. In terms of design strategy, 49.7% of studies were cross-sectional, 35.5% were prospective, and 14.8% were retrospective studies. The main language of 99.3% of articles was Farsi, and 0.7% was English. Majority of articles, 38.7%, were written by two authors. Gender of corresponding author in 66.7% of articles was male, and in 33.3% of articles was female. There was an increasing trend in percentage of original studies, clinical trials and female corresponding authors. In terms of publications in Pubmed, a total of 75 dental articles from Iran were electronically available. Significant differences were revealed in terms of number of authors, study types and design strategies when compared to publications in domestic journals.
A number of encouraging trends were identified, which is a reflection of improvements in quality of domestic electronic dental literature. However, as the majority of articles are written in Farsi, availability of research evidence to the international community is limited. Overall, results of this study indicate the need for future bibliometric analyses which can be used to construct a comprehensive database that will assist in evidence-based clinical decision making.
对1983年至2006年伊朗所有电子可得的牙科文献进行文献计量分析，以研究其可得性并审视趋势。
获取国内期刊发表的所有电子可得的伊朗牙科文章，并将结果与发表在PubMed上的伊朗牙科文章进行比较。从每篇文章中收集以下数据：期刊名称、出版年份、作者数量、通讯作者性别、作者学术水平、文章主要语言、摘要语言、研究环境、研究人群、牙科领域、文章类型、设计策略、研究设计和分析设计。
就国内期刊发表情况而言，共有1994篇牙科文章以电子形式可得，发表在伊朗的六种不同牙科期刊上。大多数文章（84.5%）为原创研究。就设计策略而言，49.7%的研究为横断面研究，35.5%为前瞻性研究，14.8%为回顾性研究。99.3%的文章主要语言为波斯语，0.7%为英语。大多数文章（38.7%）由两位作者撰写。66.7%文章的通讯作者为男性，33.3%为女性。原创研究、临床试验和女性通讯作者的比例呈上升趋势。就PubMed上的发表情况而言，共有75篇来自伊朗的牙科文章以电子形式可得。与国内期刊发表情况相比，在作者数量、研究类型和设计策略方面存在显著差异。
发现了一些令人鼓舞的趋势，这反映了国内电子牙科文献质量的提高。然而，由于大多数文章是用波斯语撰写的，国际社会获取研究证据的机会有限。总体而言，本研究结果表明未来需要进行文献计量分析，以构建一个有助于循证临床决策的综合数据库。
