Author characteristics and the extent of dental literature authorship globalization have not been widely investigated, especially in prosthodontics.
The purpose of this study was to examine trends in authorship characteristics in prosthodontics.
Articles published in The Journal of Prosthetic Dentistry (JPD), International Journal of Prosthodontics (IJP), and Journal of Prosthodontics (JP) in 1998, 2003, and 2008 were reviewed. Abstracts, letters to the editor, and book reviews were not included in the investigation. The authors' educational degrees had to be listed in the publications for the articles to be included. For each article, number of authors, degrees of all authors, academic ranks of first and last authors, and geographic origin were recorded. Descriptive and analytic analyses (alpha=.05), including a generalized linear model, Kruskal-Wallis, Mann-Whitney U, or chi-square tests, were used as appropriate.
A total of 998 articles met the inclusion criteria from the 3 selected journals for the years studied. Across all 3 journals, the mean number of authors per article increased significantly from 2.9 in 1998 to 3.6 in 2008 (Kruskal-Wallis, P<.001). The mean number of authors per article increased steadily on all continents, except for Africa and Oceania. A steady increase of authors with higher degrees was observed. There was a significant increase in the proportion of senior-ranking faculty as last author over time (chi-square=5.57, df=1, P=.018). The contributions from Asia and South America increased over time.
The number of authors per article, the number of authors with higher educational degrees, and the percentage of senior-ranking faculty as last author steadily increased in the prosthodontic literature from 1998 to 2008. The trend of globalization of authorship was evident in the prosthodontic literature.
作者特征和牙科文献作者全球化的程度尚未得到广泛研究，尤其是在修复学领域。
本研究旨在探讨修复学领域作者特征的趋势。
回顾了 1998 年、2003 年和 2008 年发表在《修复学杂志》（JPD）、《国际修复学杂志》（IJP）和《修复学杂志》（JP）上的文章。本研究未包括摘要、给编辑的信和书评。只有在出版物中列出作者的教育程度，文章才被包括在内。对于每一篇文章，记录了作者人数、所有作者的学位、第一作者和最后作者的学术职称以及地理来源。使用描述性和分析性分析（alpha=.05），包括广义线性模型、Kruskal-Wallis、Mann-Whitney U 或卡方检验，根据需要进行。
从 3 种选定期刊中对研究年份进行筛选，共纳入 998 篇文章。在所有 3 种期刊中，每篇文章的平均作者人数从 1998 年的 2.9 人显著增加到 2008 年的 3.6 人（Kruskal-Wallis，P<.001）。除了非洲和大洋洲，所有大陆的每篇文章的平均作者人数都在稳步增加。作者具有更高学位的比例也在稳步增加。随着时间的推移，高级教职人员作为最后作者的比例显著增加（卡方=5.57，df=1，P=.018）。来自亚洲和南美洲的贡献也随着时间的推移而增加。
从 1998 年到 2008 年，修复学文献中每篇文章的作者人数、具有更高教育程度的作者人数以及高级教职人员作为最后作者的比例稳步增加。在修复学文献中，作者全球化的趋势显而易见。
