A bibliometric analysis of current trends, hotspots, and future aspects of endodontic-periodontal lesions

Aim: This study aims to examine the present findings, contemporary developments, and productivity of endodontic-periodontal (endo-perio) lesions based on the top 50 most-cited articles between 1990 and 2022. Methodology: An electronic search was carried out in the " Clarivate Analytics Web of Science, All Databases". After ranking the articles in descending order based on their citation counts, the first 50 relevant articles were selected. Parameters such as citation density, publication year, journal, country, institution, author, study design, evidence level, and keywords were analyzed. Spearman's correlation was used to determine associations between the number of citations and citation density. Results: There was a significant positive correlation between citation number and the age of publication (p<0.05). Articles were mostly published between 2011 and 2022. The Journal of Endodontics had the largest number of publications. The United States and The University of Southern California made the highest contribution. The majority of the articles were case reports. Ilan Rotstein, Se-Lim Oh, and Maryam Pourhajibagher were the most frequent first authors. Studies were frequently designed as case reports with evidence level V. "Endo-perio lesions" followed by "guided tissue regeneration" were mostly-used keywords. Conclusion: Regenerative procedures along with endodontic treatments have been utilized in the last decade to manage endo-perio lesions due to the developments in materials and techniques. Case reports could guide dental practitioners by demonstrating updated information in this field.
