Abstract

Aim: To identify the top 100 most-cited case reports and case series published in Endodontic journals and to analyse their bibliometric characteristics.

Methodology: The Clarivate Analytics' Web of Science (WoS), Scopus and PubMed databases were used to identify the top 100 most-cited case reports and case series in Endodontic journals. Complete bibliographic records of the selected case reports and case series were exported in plain text or BibTeX format and imported into the R environment for statistical computing and graphics. The following parameters were then analysed: names and affiliations of the authors, title, year of publication, journal of publication, first author, corresponding author, literature cited within reports, language, citation counts, impact factor of the journal, keywords, Keywords Plus and research topic.

Results: In total, 88 case reports and 12 case series published in English between 1977 and 2016 were identified as the most-cited reports in the field of Endodontics. The terms "case report(s)" or "case series" were not included in the title of 57 articles. The number of authors per report ranged from one to seven, with the average number of co-authors per report being 3.14. The most-cited author was M Trope (University of Pennsylvania, USA). The University of Washington and Private Practice, Cetraro, Italy, were the most productive institutions. The country whose case reports received the largest total number of citations was the United States. The largest number of the most-cited reports appeared in 2002, 2004 and 2007 (n = 7, respectively). According to the WoS database, the total number of citations ranged from 42 to 453, with the average number of citations per report being 79.97. The majority of the top 100 most-cited articles were published in the Journal of Endodontics and the International Endodontic Journal. The most frequently used author keywords were revascularization and mineral trioxide aggregate. The majority of the case reports and case series dealt with topics related to pulp regeneration.

Conclusion: This bibliometric study provides a comprehensive overview on the progress, trends and current directions in clinical practice within the field of Endodontics.

Keywords: bibliometrics; case reports; case series; citations; endodontics.
