INTRODUCTION Bibliometric analysis is the quantitative measure of the impact of a scientific article in its respective field of research. The aim of this study was to identify and analyze the main features of the top 50 most-cited articles published in Journal of Endodontics since its inception as well as the top 50 most downloaded articles in 2017 and 2018 in order to evaluate the changing trends and other bibliometric parameters of the contemporary literature as compared to the classic literature. METHODS An electronic search was conducted on the Clarivate Analytics' Web of Science (WoS) "All Databases to identify and analyze the top 50 most frequently cited scientific papers. After ranking the articles in a descending order based on their citation counts, each article was then cross matched with the citation counts in Scopus, Google Scholar and PubMed. RESULTS The citation counts of the 50 selected most-cited articles ranged between 218 and 731 (WoS). The years in which most top 50 articles were published were 2004 and 2008 (n=5). Among 131 authors, the greatest contribution was made by Torabinejad M (n=14). Most of the articles originated from the United States (n=38) with the greatest contributions from the School of Dentistry, Loma Linda University, USA (n=15). Basic research-technology was the most frequent study design (n=18). A negative, significant correlation occurred between citation density and publication age (correlation coefficient = -0.708, p < 0.01). CONCLUSIONS Several interesting differences were found between the main characteristics of the most-cited articles and the most downloaded articles.
