Abstract：
OBJECTIVE: During Chile\'s period of social unrest, numerous people suffered physical trauma due to the use of police force. However, there have been no reports regarding traumatic dental injuries (TDIs) suffered in this context. This study aims to describe the dental trauma of patients injured by police during the social unrest period in Chile from 2019 to 2021.
METHODS: A case series methodology was employed. Following informed consent, clinical records of patients admitted to the Ocular and Dentomaxillofacial Prosthetic Care and Rehabilitation Program, who were affected by the violence of state agents during social mobilizations, were reviewed from October 2019 to December 2021. Information on the sociodemographic characteristics of the patients and the TDI diagnoses with their treatment needs were collected. A descriptive analysis was performed.
RESULTS: Forty-six patients were identified, nine of whom agreed to the informed consent. Most were male, with a mean age of 28 years, public health insurance, and a high educational level. The most common causes of injury were kinetic impact projectiles (KIPs) and the use of physical force (punches, kicks, or pushes). Of the nine cases described, 26 teeth were affected by TDI. The most affected teeth were the central upper incisors and, in most cases, they presented lesions in both injury categories: NA0D.0 (the tooth and pulp) and NA0D.1 (periodontal tissues). Treatment needs varied and included some complex procedures, such as implant-retained crowns and removable dental prostheses.
CONCLUSIONS: The use of force by police during the period of social unrest in Chile caused TDIs among demonstrators, which were mainly due to physical force from less-than-lethal weapons. Most cases presented injuries affecting the incisors with multiple teeth requiring complex treatments.

摘要：
目的：在智利社会动荡时期，许多人由于使用警察部队而遭受身体创伤。然而,在这种情况下，没有关于创伤性牙齿损伤（TDI）的报道。这项研究旨在描述2019年至2021年智利社会动荡期间警察受伤的患者的牙齿创伤。
方法：采用病例系列方法。知情同意后，接受眼和牙颌面修复护理和康复计划的患者的临床记录，他们在社会动员期间受到国家工作人员暴力的影响，从2019年10月至2021年12月进行了审查。收集了有关患者的社会人口统计学特征和TDI诊断及其治疗需求的信息。进行了描述性分析。
结果：确定了46例患者，其中9人同意知情同意。大多数是男性，平均年龄28岁,公共健康保险,和高的教育水平。最常见的伤害原因是动力冲击弹丸（KIP）和使用物理力（冲头，踢,或推动)。在描述的9个案例中，26颗牙齿受TDI影响。受影响最大的牙齿是中央上切牙，在大多数情况下,他们在两种损伤类别中均出现病变：NA0D.0（牙齿和牙髓）和NA0D.1（牙周组织）。治疗需求各不相同，包括一些复杂的程序，如种植体保留的牙冠和可移动的假牙。
结论：在智利社会动荡期间，警察使用武力引起示威者的TDI，这主要是由于低于致命武器的物理力量。大多数病例表现出影响门牙的损伤，多颗牙齿需要复杂的治疗。
