Bioactive Glass in Dentistry: A Bibliometric Analysis of Trends, Impact, and Future Directions.

Abstract

This bibliometric analysis examined research on bioactive glass in dentistry from 2015 to 2024, identifying key trends, its impact on dental applications, and future research directions. Data were collected from Web of Science and Scopus in April 2025, focusing on studies published between 2015 and 2024 using the keywords "Dentistry" AND "Bioactive Glass." A total of 2114 studies from 706 sources were analyzed, involving 7471 authors with an average of 5.78 coauthors per article. The analysis used Web of Science and Scopus, which provide comprehensive access to peer-reviewed literature in dentistry and materials science. Prominent journals included Dental Materials, Ceramics International, Materials, Journal of the Mechanical Behavior of Biomedical Materials, and Journal of Dentistry. There was a notable increase in publications, with 52 articles in 2024. The average number of citations per document was 15.61, and the average document age was 4.72 years. Collaborative research, especially among Saudi Arabia, Egypt, China, the United States, and Brazil, was a significant trend. Leading institutions included the Egyptian Knowledge Bank, University of London, and King Abdulaziz University, reflecting substantial contributions from the Middle East, Europe, and Asia. Core research topics focused on bioactive glass, mechanical properties, nanoparticles, bioactivity, and hydroxyapatite. The study highlights a growing global interest in bioactive glass, particularly in relation to dentin hypersensitivity, remineralization, and tissue regeneration. The continued rise in publication volume and expansion of international collaborations underscore the vitality of this field. Emerging directions such as bone regeneration, antibacterial applications, and advancements in the mechanical performance of bioactive materials are likely to shape the trajectory of future research. Impact Statement This bibliometric analysis highlights the growing significance of bioactive glass in dentistry, particularly in the context of remineralization, tissue regeneration, and antimicrobial protection. The increasing volume of research, highlighted by a surge in publications and international collaborations, reflects the expanding interest in bioactive glass. Prominent research areas include remineralization, hydroxyapatite applications, and mechanical properties of bioactive materials, with implications for bone regeneration and innovative dental treatments. By identifying trends and leading contributors, this study provides a foundation for future research aimed at enhancing the clinical applications and material science of bioactive glass in dentistry.
