Gelatin methacryloyl advances in regenerative dentistry: A global bibliometric analysis

This study aims to comprehensively appraise the bibliometric features of articles evaluating the utilization of gelatin methacryloyl (GelMA) in dentistry by conducting a bibliographic search on the Web of Science databases until January 2025.

The following data were gathered: number and density of citations; authors; year, journal of publication and impact factor; study design and theme; keywords; institution and country of origin. The collaborative network was identified with the VOSviewer software and used to generate collaborative network maps for authors and keywords.

A total of 133 articles reporting the use of GelMA in dentistry were included. The articles were published between 2014 and 2025, and the most prevalent journals were Dental Materials (10,17% and 276 citations) and Acta Biomaterialia (10,1% and 208 citations) The most frequent study designs and themes were laboratory-based in vitro studies (58,6%) and endodontics (37,6%), respectively. Bottino MC (9%; 464 citations) and Dubey N (4,5%; 345 citations) were the most prominent authors in the list. Most articles originated from China (52,6%) and the United States (29,3%). University of Michigan (12,8%) and Sichuan University (6,7%), located in the USA and China, respectively, were the institutions with the most articles. There was a strong negative correlation between the number of citations and the year of publication, with the most recent articles being the most cited.

Global articles related to the use of GelMA in dentistry were published mainly in China, with laboratory-based studies conducted in vitro addressing topics related to the use of GelMA in endodontics. Key words:Gelatin Methacryloyl, Dental Materials, Bibliometric Analysis.
