BACKGROUND/AIMS: Traumatic dental injuries (TDIs) are considered to be a public dental health problem worldwide. The aim of the current study was to provide the worldwide tendency and perspectives in TDIs in the last two decades via bibliometric analysis.
''Tooth injuries'' was searched as the Medical Subject Headings term within PubMed with the date range from 1999 to 2018. Two investigators perused information in the articles according to the inclusion and exclusion criteria. The articles were independently categorized according to the following aspects: (a) annual scholarly output; (b) leading countries or regions; (c) leading journals; (d) productive authors; (e) citations; (f) study design; (f) distribution of topics; and (g) the type of dentition and TDIs. VOSviewer 1.6.7 and Citespace 5.2 were used for analyzing and visualizing bibliometric networks.
A total of 2627 articles about traumatic dental injuries were published and indexed in PubMed during the two decades, and the number of publications on traumatic dental injuries was rising in general. The research outputs were mainly concentrated in developed countries and affiliated hospitals of universities. Brazil was the most productive country. The journal Dental Traumatology had the most contributions to the scientific research of traumatic dental injuries. "Case report" was the most frequent type of article (36.50%), followed by cross-sectional studies (19.57%) and case-control studies (13.67%). Most studies focused on the treatment of TDIs (38.94%), especially for avulsion (21.01%), crown fracture (9.71%), and intrusion (5.25%). Permanent teeth (66%) were the dominant dentition.
There is a lack of high-quality well-designed studies such as cohort studies. The number of publications on prevention and the primary dentition is disproportionate in relation to their significance.
背景/目的：外伤性牙损伤（TDI）被认为是全球公共口腔健康问题。本研究的目的是通过文献计量分析提供过去二十年全球 TDI 的趋势和研究角度。
在 PubMed 中，以主题词“Tooth injuries”作为检索词，检索范围为 1999 年至 2018 年。两名研究者根据纳入和排除标准阅读文章中的信息。根据以下方面对文章进行独立分类：（a）年度学术产出；（b）主要国家或地区；（c）主要期刊；（d）有影响力的作者；（e）引用次数；（f）研究设计；（g）主题分布；（h）牙列和 TDI 的类型。使用 VOSviewer 1.6.7 和 Citespace 5.2 分析和可视化文献计量网络。
在过去的二十年中，共在 PubMed 上发表了 2627 篇关于外伤性牙损伤的文章，总的来说，外伤性牙损伤的研究产出呈上升趋势。研究成果主要集中在发达国家和大学附属医院。巴西是最具生产力的国家。期刊《牙外伤杂志》对外伤性牙损伤的科学研究贡献最大。“病例报告”是最常见的文章类型（36.50%），其次是横断面研究（19.57%）和病例对照研究（13.67%）。大多数研究集中于 TDI 的治疗（38.94%），特别是牙脱位（21.01%）、冠折（9.71%）和嵌入（5.25%）。恒牙（66%）是主要的牙列。
缺乏高质量的设计良好的研究，如队列研究。关于预防和初级牙列的研究数量与其重要性不成比例。
