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

OBJECTIVE: 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. METHODS: 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. RESULTS: 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. CONCLUSION: 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.
