Exploring vital pulp Therapies: A bibliometric analysis of the most cited articles

The aim of this study was to identify and analyze the most cited articles on vital pulp therapies.

Bibliographical data related to the abstract, citations, keywords, and other relevant information was extracted using different combinations of keywords. Further evaluation and visualization of the selected data were performed with the help of various tools, including MS Excel, Microsoft Word, Google open refine, BibExcel, and VOS viewer. An initial search revealed 91 documents, of which 40 were chosen for further analysis. We used the Kolmogorov-Smirnov test and Spearman correlation coefficient test, and our adopted significance level was p < 0.05.

In total, the articles received 1,905 citations, with six of them receiving at least 100 citations. Among the top 40 articles, the United States of America (10 articles) and Ireland (6 articles) were the countries with the highest number of cited articles. The journals "Journal of Endodontics" (14 articles; 650 citations) and "International Endodontic Journal" (13 articles; 577 citations) published most of the articles among the 50 most cited ones. Duncan H. was the author with the highest number of works cited (11 articles; 339 citations). Of the articles, systematic reviews accounted for 32%, literature reviews for 14%, in vitro experimental studies for 12%, clinical trials for 8%. Among the biomaterials used in vital pulp therapies, mineral trioxide aggregate (MTA) was discussed in 37 articles (74%), followed by calcium hydroxide, mentioned in 30 studies (60%). Interestingly, the publication year did not demonstrate a significant impact on citation count.

The present study provided a detailed list of the top 50 most cited and classic articles on vital pulp therapies. This will help researchers, students, and clinicians in the field of endodontics with an impressive source of information.
