Abstract：
Objective: Based on the application and funding status of National Natural Science Foundation of China (NSFC) in the field of oral and craniofacial sciences (H15), we analyzed the current status of basic research of the Oral and Craniofacial Sciences (OCS) in China, and provided the references for the sustainable and efficient funding of basic research and scientific frontier exploration in the field, supporting the construction of talents and teams, and enhancing the development of OCS in China. Methods: The data of both applied and funded grants of H15 in NSFC from 2010 to 2021 were analyzed, including the number of applications and funding, the amount of funding, the funding rate, the research direction and the supporting units. The status of basic research of H15 was summarized. Results: From 2010 to 2021, H15 received 15 060 applications and funded 2 569 grants. The overall funding rate of H15 was 17.06%, and the total funding amount was 1 140.305 million yuan. The applications and funded projects of H15 were mainly focused on the General Projects and Youth Science Fund Projects, accounting for 90.33% (13 604/15 060) and 88.71% (2 279/2 569) of the total number of applications and funded projects, and 78.05% (89 002.5/114 030.5) of the total funding amount. In terms of talent training, the National Science Foundation for Distinguished Young Scholars received 65 applications, and 6 were founded, with a funding rate of 9.23%. The National Science Foundation for Outstanding Young Scholars received 85 applications, and 13 were founded, with a funding rate of 15.29%. In recent years, the number of applications has gradually increased and the number of grants has remained relatively stable. Among the nine sub-categories of H15, the top three in terms of the number of applications and grants were H1502, H1504, and H1507. H1502 (repair and regeneration of oral and craniofacial tissue and organ defects) received 2 760 applications, and 510 were funded. H1504 (periodontal and oral mucosal diseases) received 2 475 applications, and 419 were funded. H1507 (restoration of tooth defects and loss, and correction of dental deformities) received 2 270 applications, and 367 were funded. Peking University and Sichuan University ranked first and second with 1 092 and 1 001 applications, respectively. The top five recipients were Sichuan University (327 items), Peking University (260 items), Wuhan University (204 items), Shanghai Jiao Tong University (198 items) and the Fourth Military Medical University of the People\'s Liberation Army (193 items). The funding rates were 32.67%, 23.81%, 23.02%, 21.69% and 29.11%, respectively. Conclusions: Under the support of NSFC, the basic research of oral and craniofacial sciences has been developed in an all-round way. In recent years, the talent training of all echelons has increased year by year, the research direction and geographical coverage is comprehensive, and project support organization has its own research focus and discipline advantages, making contributions to the realization of the goal of healthy China and the progress of world medicine.
目的： 基于国家自然科学基金口腔颅颌面科学（H15）领域申请和资助现状，分析我国口腔颅颌面科学领域基础研究的现状，为持续高效资助领域内基础研究和科学前沿探索，支持人才和团队建设，增强我国口腔颅颌面科学发展提供参考。 方法： 分析国家自然科学基金2010至2021年口腔颅颌面科学项目申请及资助项目情况，主要分析内容为申请数量、资助数量、资助金额、资助率、研究方向、依托单位等，总结口腔颅颌面科学基础研究现状。 结果： 2010至2021年间，口腔颅颌面科学接收项目申请15 060项，资助2 569项，资助率为17.06%，资助金额共114 030.5万元。近年来，申请数量逐步上升，资助数量相对稳定。申请和资助项目主要集中于面上项目和青年项目，两项共占总申请项目数的和总资助项目数的90.33%（13 604/15 060）和88.71%（2 279/2 569），两项共占总资助金额的78.05%（89 002.5/114 030.5）。在人才培养方面，国家杰出青年科学基金项目资助率为9.23%（6/65）。国家优秀青年科学基金项目资助率为15.29%（13/85）。在9个二级代码下，申请数量和资助数量位于前3位的分别为：H1502（口腔颅颌面组织器官缺损修复与再生）申请数量2 760项，资助数量510项；H1504（牙周及口腔黏膜疾病）申请数量2 475项，资助数量419项；H1507（牙缺损、缺失修复及牙颌畸形的矫治）申请数量2 270项，资助数量367项。北京大学和四川大学的申请数量位列第一和第二位，分别为1 092和1 001项。资助数量位于前5位的依托单位依次为四川大学（327项）、北京大学（260项）、武汉大学（204项）、上海交通大学（198项）和中国人民解放军第四军医大学（193项），资助率分别为32.67%、23.81%、23.02%、21.69%和29.11%。 结论： 在科学基金的支持下，口腔颅颌面科学的基础研究得到了全面发展，各梯队的人才培养逐年递增，学科资助的研究方向和地域覆盖均较全面，各依托单位具有各自的研究重点和学科优势。.
