Gelatin methacryloyl advances in regenerative dentistry: A global bibliometric analysis

Adriana Poli Castilho Dugaich et al. J Clin Exp Dent. .

Abstract

Background: 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.

Material and methods: 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.

Results: 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.

Conclusions: 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.
