口腔四手操作技术研究热点的共词聚类分析

目的：分析PubMed数据库中关于口腔四手操作技术的研究热点，为了更好的研究、应用、推广此技术，提高口腔科工作效率。方法：以Dentistry, Operative和Assistant作为检索词，同时以“Proprioceptive Derivation Concept”、“Four-handed Dentistry”搜索PubMed数据库，提取时间为2020年3月1日，检索相关文献，文献类型不限，语言不限。使用Bicomb软件、SPSS软件和gCLUTO软件对其进行文献计量及聚类分析。结果：共检索到文献591篇，根据纳入和排除标准剔除不相关文献，最终纳入572篇。国外口腔四手操作技术发展较早，且相对比较成熟，发表的文献主要集中在美国、英国和日本。目前四手操作已应用于牙体牙髓科、修复科、正畸科、儿童牙科、口腔外科等各个领域，研究了医护任务执行与分析、临床教学与继续教育、职业疼痛预防、器械摆放与传递、医护患操作体位、配合操作原则、设备仪器研发、感染控制等方面。发文数量最多的国家是美国269篇，占47.028%；发文数量最多的杂志是英国的《Journal of dental education》。结论：国外口腔四手操作技术趋向成熟，国内可借鉴有效经验，提高四手操作展开率，全面推广应用，切实提高工作效率，避免医院感染的发生。

Cluster analysisof common words in research hotspots offour-hand dentistry

Objective:Toanalyze the research hotspots of four-hand dentistry in the PubMed database, inorder to advance research, application and promotion of this technology, so asto improve the work efficiency of the department of stomatology.Methods:Dentistry, Operative and Assistant were used as retrievers, and"Proprioceptive Derivation Concept" and "four-handedDentistry" were used to search PubMed database. The extraction time was onMarch 1, 2020, and relevant literatures were retrieved without limitation ofliterature type or language. BICOMB, SPSS and gCLUTO software were used forBibliometric analysis and cluster analysis. Results:A total of 591 literatureswere retrieved and 572 literatures which met the criteria were finally includedafter screening. The development of oral four-hand manipulation techniquesabroad was earlier and relatively mature.The published literatures were mainlyconcentrated in the United States, Britain and Japan. Four hand operation hadbeen applied in tooth pulp, repair, orthodontics, pediatric dentistry, oralsurgery, etc.The research field included the medical task execution andanalysis, clinical teaching and continuing education, prevention of vocationalpain, instrument display and transmission, medical operation position, withresearch and development of operating principles, equipment, instruments,infection control, etc. The United States had the largest number of articles,accounting for 47.028%. The Journal with the highest number of articles was theJournal of Dental Education in Britain. Conclusion:Oral four-hand dentistrytechnology abroad tends to mature and we can learn some effective experience,so as to improve the rate of four-hand dentistry for comprehensive promotionand application, meanwhile, improve the work efficiency and avoid nosocomialinfection.
