Research trends on bioceramics in endodontics: A bibliometric analysis from 2001 to 2020

Purpose: This study aimed to identify the top 100 articles about bioceramics in endodontics using the average number of citations per year (A/Y) metric and compare them with the top 100 most-cited articles.
Methods: A detailed search strategy was conducted on the “Clarivate Analytics Web of Science, All Databases”. After ranking the articles in descending order based on their A/Y and citation counts, 100 articles of each list were selected and analyzed concerning publication year, journals, country, institution, authors, study design, the field of study, evidence level, and keywords.
Results: The number of citations in 2001–2010 was significantly higher (p < 0.05). Journal of Endodontics, the United States, and the University of Bologna were the most productive journal, country, and institution. The most frequent first authors were Camilleri and Torabinejad. The main study fields and most used keywords were ‘material properties’ and ‘Silicates’.
Conclusion: The A/Y metric has allowed identifying fairly-recent influential articles about bioceramics; therefore, it could be used as a valid alternative. Future developments in the material properties of bioceramics could lead to the effective use of these materials for various endodontic treatments. Recent research trends implicating innovative materials or techniques might raise new interest areas regarding this field.
