现代高等口腔医学教育在中国起步很早，发展至今历史已逾百年，但目前国内对口腔医学教育的研究并不充分。本研究着重关注了口腔医学高等教育的发展，收集近30年口腔医学博士学位论文的数据，基于Citespace进行可视化分析与总结。结果显示，虽然研究的具体内容和方法一直在发展进步，但口腔医学博士学位论文的研究领域大多与"骨"息息相关。口腔医学博士学位论文中，关键词按频次排名前10位里有8个与"骨"有直接关联（成骨细胞、成骨分化、牙周炎、组织工程、生物力学、下颌骨、种植体和破骨细胞），另2个高频关键词分别是增殖和分化。骨研究在口腔医学博士论文中受到追捧是临床导向的结果，但同时口腔医学仍有许多值得关注的疾病，如龋病、口腔癌前病变及头颈部肿瘤等，数十年来这些口腔疾病的治疗方式及预后并未得到显著的改善。因此，口腔医学高等教育的关注点也应该更加多元化，以推动我国口腔医学教育事业的蓬勃发展。

Modern higher education of stomatology started very early in China, and has developed for more than 100 years. However, the domestic research on stomatology education is not sufficient. This study focused on the development of higher education of stomatology, through collecting the data of around 30 years of doctoral dissertations in stomatology, and conducting a visualization analysis based on Citespace. It was found that although the specific content and methods of research had been developing and progressing, most doctoral dissertations in stomatology were closely related to "bone" . Among the top 10 keywords in the doctoral dissertations of stomatology, eight were directly related to "bone" , including osteoblasts, osteogenic differentiation, periodontitis, tissue engineering, biomechanics, mandible, implants and osteoclasts, while the other two were proliferation and differentiation. The popularity of bone research in dental doctoral dissertations may be a clinically oriented consequence. However, there are many other diseases worthy of attention in stomatology, such as caries, oral precancerous lesions, and head and neck cancers, whose treatment and prognosis have not been significantly improved for the past few decades. Therefore, more research topics should be focused so as to promote the development of higher education of stomatology in China.
