This study evaluated the quantity of prosthodontic literature produced globally by continent in three prosthodontic journals over a 10-year period, 1998-2008. Prosthodontic research productivity relative to economic status of countries and collaboration among countries grouped by economic status was assessed.
Three peer-reviewed prosthodontic journals were used for the analysis of articles published in 1998, 2003, and 2008: The Journal of Prosthetic Dentistry, International Journal of Prosthodontics, and Journal of Prosthodontics. The country of every author listed for each included article was recorded. The number of articles published by each continent and each country was reported. Countries were grouped according to the World Bank economic classification system, and the number of articles published by each economic class was found.
The majority of publications over the 10-year period were produced in Asia (Japan), Europe (Germany), and North America (USA). Productivity declined by 14.4% in high-income countries while it increased in upper middle-, lower middle-, and low-income countries. The majority of publications written by upper and lower middle- and low-income countries were independent works. Articles resulting from collaboration increased over time for all economic classes of countries.
The origins of prosthodontic literature are becoming more geographically and economically diverse, with increased contributions from Africa, Asia, and South America, and middle- and low-income countries between 1998 and 2008. Collaboration between high-income countries and the other economic group countries increased over time.
本研究通过对 1998 年至 2008 年 10 年间 3 种口腔修复学杂志的文献评估，分析了全球各大陆在口腔修复学领域的文献产出量。评估了各国的口腔修复学研究生产力与其经济地位的相关性，以及按经济地位分组的国家之间的合作情况。
本研究使用了 3 种同行评审的口腔修复学杂志，即《修复牙科杂志》、《国际口腔修复学杂志》和《修复牙科杂志》，对 1998 年、2003 年和 2008 年发表的文章进行了分析。记录了每篇文章中列出的每位作者的国家。报告了每个大陆和每个国家发表的文章数量。根据世界银行的经济分类系统对国家进行分组，确定了每个经济类别的文章发表数量。
在这 10 年期间，大多数出版物来自亚洲（日本）、欧洲（德国）和北美（美国）。高收入国家的生产力下降了 14.4%，而上中、中下和低收入国家的生产力则有所提高。来自中上、中下和低收入国家的大多数出版物都是独立完成的。随着时间的推移，所有经济类别的国家的合作出版物数量都有所增加。
口腔修复学文献的来源在地理和经济上变得更加多样化，非洲、亚洲和南美洲以及中低收入国家在 1998 年至 2008 年间的贡献有所增加。高收入国家与其他经济类别的国家之间的合作也随着时间的推移而增加。
