The essential endodontic literature: a survey of postgraduate program directors

Hundreds of new articles are added to the body of knowledge in endodontics each year. However, a comparatively small number of articles have had a disproportionately large influence on the progress and development of the specialty of endodontics. A survey of postgraduate program directors was conducted to attempt to identify a highly selective short list of articles that program directors felt should be included on every postgraduate reading list. The survey results were then compared with the more objective benchmark of citation indexing. The results of this survey suggest that the collective opinion of the postgraduate program directors correlates well with the results obtained from citation analysis.
