目的:本研究旨在分析过去70年根尖周炎的相关研究,展示目前的研究现状,探讨热点及展望未来.方法:从Web of Science Core Collection数据库中检索1952年至2022年关于根尖周炎的文献,主要通过CiteSpace and VOSviewer等进行分析,分析内容主要包括国家、机构、作者、期刊、被引期刊、关键词等.结果:该领域文献数量的增长可以分为两个阶段:1952年至1990年和1991年至2022年,整体趋势呈逐渐增长.美国是该领域贡献最大的国家,同时也是合作的中心.Univ Sao Paulo是生产力最高的大学.Siqueira J F是学术影响力最高的学者.Journal of endodontic和International endodontic journal是该领域的核心期刊.根据关键词分析,将该研究领域分为6个关联的集群:1.发病机制的基础研究;2.治疗;3.诊断;4.感染;5.牙髓再生;6.流行病学.巨噬细胞、氧化应激、牙髓再生、根管药物等研究方向仍然是近期的研究热点,值得进一步关注.结论:本研究是一项全面描述根尖周炎研究的文献计量分析,可为研究人员进一步探讨该领域提供一定的参考.
Emerging trends and hotspots of apical periodontitis based on bibliomertrics
AIM:This study aims to analyze the relevant research on apical periodontitis in the past 70 years,to present the current status,explore hotspots and frontiers,and provide insights into future research directions through bibliometric analysis.METHODS:Literature on apical periodontitis from 1952 to 2022 was retrieved using the Web of Science Core Collection database.Bibliometric analysis was performed using CiteSpace and VOSviewer.The main analysis contents included countries,institutions,authors,journals,cited journals,keywords,etc.RESULTS:The growth of literature in this field can be divided into two stages:1952 to 1990 and 1991 to 2022,with an overall trend of gradual increase.The United States acted as the center for collaboration among different countries/regions and also had the highest productivity and citation count.Univ Sao Paulo was the university with the highest productivity in this field,and Siqueira JF was the scholar with the highest academic influence.Journal of Endodontic and International Endodontic Journal were identified as core journals in this field.Based on keyword analysis,the research field was divided into six related clusters:1.Etiology;2.Treatment;3.Diagnosis;4.Infection;5.Pulp regeneration;6.Epidemiology."Macrophages,""oxidative stress,""pulp regeneration,"and"antibiotics"were identified as the main keywords highlighting research hotspots that deserve further attention.CONCLUSION:This study comprehensively describes the development of research in the field of apical periodontitis over the past 70 years,providing a reference for researchers and clinical practitioners.
