Abstract
Introduction: Since its inception in 1975, the Journal of Endodontics (JOE) has served as a primary platform for the publication and dissemination of research in the field of endodontics. In recognition of its fiftieth anniversary in 2025, we conducted a comprehensive bibliometric and scientometric analysis of the JOE’s publications over the past five decades to assess its evolving contributions.
Methods: Data from 8,753 articles published in the JOE between 1975 and 2024 were extracted from Elsevier®’s Scopus® database. Bibliometric indicators such as publication trends, citation dynamics, authorship patterns, thematic evolution, and journal metrics were systematically analyzed. Additionally, keyword co-occurrence mapping and collaboration networks were visualized using an advanced bibliometric software (VOSviewer™).
Results: The analysis revealed a consistent and progressive increase in the JOE’s publication output, with an average of 169.22 articles published per year and a total of 390,265 citations. Highly cited topics included root canal disinfection, regenerative endodontics, and material science innovations. Influential contributors, such as Drs. Mahmoud Torabinejad, José F. Siqueira Jr., and David H. Pashley were identified as leading figures in endodontic research. International collaboration has expanded significantly, reflecting a shift toward multidisciplinary and globally connected research efforts. Keyword analysis highlighted emerging trends, particularly in integrating advanced diagnostic technologies and biomaterials.
Conclusion: Over the past fifty years, the JOE has played a pivotal role in shaping the landscape of endodontic research, fostering innovation, and influencing clinical practice. Its impact has been marked by increasing scholarly collaboration, evolving research themes, and sustained citation growth. These bibliometric and scientometric analyses provide critical insights into the JOE’s contributions to the field and offer a roadmap for future research directions in endodontics. The findings also have practical implications for guiding editorial policies, optimizing research funding allocation, and identifying priority areas for future investigations. Furthermore, a new set of author guidelines was developed and proposed to enhance the journal’s scientific contributions and editorial efficiency.
