Changes in the prosthodontic literature 1966 to 2042.

Abstract

PURPOSE: To describe the growth and content of the prosthodontic literature over the last 4 decades, to make a prognosis on its probable development in the coming 4 decades and to discuss changes in the content of the International Journal of Prosthodontics (IJP) from its start in 1988 to 2004. METHODS: MEDLINE was searched for articles on prosthodontics published between 1966 and April 2004. All volumes of IJP were examined with respect to type, subject area and geographic origin of articles. RESULTS: Using the term "prosthodontics," the MEDLINE search produced 66,600 hits. The proportion of clinical studies increased from 1% during the first 10-year period to 13% since 2001. Articles on removable dentures decreased during the period reviewed, whereas those on implant prosthodontics increased. Randomized controlled trials were rare and often of inadequate quality. Literature reviews have become popular, but many do not follow current guidelines for systematic reviews. A marked change in geographic origin of articles in IJP has occurred, with a decrease in material from North America and an increase in that from Europe and Asia. The Internet and open-access publishing will probably have a great impact on the future development of the prosthodontic literature. CONCLUSIONS: Substantial changes have occurred in the prosthodontic literature between 1966 and 2004, and they can be expected to continue with the rapid development of information technology and increased use of the Internet.
