Abstract

Abstract: PURPOSE: To visually summarize the keywords of non-tumor research of master's and doctoral theses and analyze the research hotspots and evolution in this field. METHODS: This study collected data from master's and doctoral theses in oral and maxillofacial surgery in China from 1993 to 2023 from the China National Knowledge Infrastructure (CNKI), Wanfang, and VIP databases. Bibliometric summarization and analysis were conducted based on CiteSpace. RESULTS: The number of master's theses continued to grow from 1993 to 2012 and then stabilized, while the number of doctoral theses increased from 1993 to 2000, remained stable after 2001, peaked in 2005, and then slightly declined. At the master's level, institutions such as Shandong University and the Fourth Military Medical University had significant publication outputs, with a wide geographical distribution. At the doctoral level, the Fourth Military Medical University and Sichuan University stood out, with a more concentrated institutional distribution. Comprehensive universities and military medical universities, such as the Fourth Military Medical University, maintained advantages at both the master's and doctoral levels. High-frequency keywords in master's theses included clinical efficacy and cleft lip and palate, while animal models and mandible were high-frequency keywords in doctoral theses. Keyword clustering in master's theses mainly covered ten areas, including clinical treatment and osteoblasts, while doctoral theses focused on ten areas, such as biomechanics and bone transplantation. From 1993 to 2023, the research hotspots in oral and maxillofacial surgery in China gradually expanded from basic surgery and anatomy to diversified fields such as cells, molecules, imaging technology, and advanced clinical treatments. CONCLUSIONS: From 1993 to 2023, the non-tumor research hotspots in oral and maxillofacial surgery in China evolved from clinical practice to advanced technologies and regenerative medicine. However, further research is needed to strengthen studies on jaw development mechanisms, clinical research, and interdisciplinary collaboration.
