Injectable platelet-rich fibrin research in dentistry and medicine: A bibliometric analysis with a descriptive subanalysis of temporomandibular joint studies

Injectable platelet-rich fibrin (i-PRF) is an autologous biomaterial with expanding applications in dentistry and medicine. This study aimed to provide, to our knowledge, the first bibliometric analysis of the structure and evolution of i-PRF research. Scopus was searched on 17 October 2026. Bibliometrix and VOSviewer were used to analyze 457 publications from 2015–2025 for productivity, collaboration, and thematic evolution. Publication output increased rapidly after 2022. Compound annual growth was 60.58%, reflecting a low initial baseline. Bone and periodontal regeneration featured prominently in the keyword network. Temporomandibular joint (TMJ)-related keywords had relatively recent average publication years; 34 publications (7.4%) addressed TMJ applications. This analysis characterizes the structure and evolution of Scopus-indexed i-PRF research and may inform future research planning. Bibliometric findings do not establish the methodological quality of included studies or the clinical effectiveness of i-PRF.
