Establishing a natural population prospective cohort represents a sophisticated systematic project that spans multiple disciplines and research directions, requiring comprehensive consideration of diverse factors. Both international and domestic practices have accumulated substantial experience and achievements in this field. These prospective cohorts are typically developed through collaborative efforts among research institutions, generating systematic insights into construction backgrounds, objectives, design frameworks, implementation strategies, and management protocols. This study conducts an in-depth investigation into the current status of natural population prospective cohort development globally and domestically, systematically summarizing progress in development history, current status, and research advancements. The findings aim to inform strategic planning in China’s related domains, thereby facilitating the advancement of natural population prospective cohort research.

Objective:To statistically analyze SCI paper output and research hotspots of Chinese stomatology research institutes from 2011 to 2020.Methods:The papers of Chinese stomatology research institutions in the Web of Science database were searched and analyzed by bibliometric methods in various dimensions including publication time, institutional and journal distribution, international (regional) cooperation, and research hotspots.Results:The number and quality of publications in Chinese dental research institutions have increased significantly in the past decade, and the top four institutions in terms of publication number were Sichuan University, Peking University, Shanghai Jiaotong University, and Air Force Military Medical University. The distribution of the journals to which the articles belong was relatively scattered, and the research hotspots mainly focused on squamous cell carcinoma, periodontitis, bone regeneration, and materials science.Conclusions:The output of SCI papers and the number of high-quality papers in Chinese stomatology research institutions increased year by year during 2011-2020, and the scientific research strength continued to increase.
