[Visual analysis of global research hotspots and development trends in dental trauma]

Objective: To analyze the current global development status and research hotspots of dental trauma-related studies, to provide references for future research in this field in China. Methods: Literature related to dental trauma, published from the inception of the Web of Science Core Collection up to December 27, 2025, was retrieved. Visualization analysis was conducted using Bibliometrix, VOSviewer, CiteSpace, and Excel. Results: A total of 2 639 publications were included. The annual publication output showed an overall increasing trend with fluctuations. Levin L was the most prolific author, the Universidade Federal de Minas Gerais was the leading institution, and Brazil was the most productive country/region. Andreasen JO was the most frequently co-cited author, Dental Traumatology was the most frequently co-cited journal, and the reference by Petti et al (2018) was the most frequently co-cited. The top five high-frequency keywords were: "dental trauma, " "teeth, " "traumatic dental injury, " "injury, " and "children." The top five keywords with the highest centrality were: "children, " "dental trauma, " "adolescents, " "tooth avulsion, " and "emergency management." The log-likelihood ratio (LLR) algorithm identified 15 keyword clusters, with "pediatric dentistry" emerging as a burst keyword in 2023. Conclusions: Current global research on dental trauma shows a diversified development trend. In the future, China can further deepen its research in areas such as regenerative medicine, the clinical application of novel biomaterials, precision diagnosis and treatment, multidisciplinary management models, long-term prognosis evaluation, and intelligent assisted diagnosis and treatment.
