The aim of the present cross-sectional study was to investigate the knowledge of undergraduate students and teachers at all physical education courses in the city of Belo Horizonte (Brazil) regarding first-aid measures to be taken following tooth avulsion as well as the need for the preventative use of mouth guards. The sample consisted of 442 individuals (Group 1: 53 teachers; Group 2: 389 undergraduate students). Data collection was carried out with the administration of a questionnaire with both objective and subjective questions addressing definitions, first-aid measures in cases of avulsion and tooth replantation, together with an assessment of the use and indication of mouth guards. Data analysis involved descriptive statistics and the chi-square test. The results revealed that 45.1% of the participants in both groups knew what a tooth replantation was. However, 91.6% judged themselves incapable of performing an immediate replantation. Among the overall sample, 45.9% has no knowledge on first-aid measures regarding tooth avulsion; sending the patient with an avulsed tooth to the dentist was the most often cited measure (42.3%). Immediate replantation was cited by 20.6% of the individuals in Group 1 and 5.9% of the individuals in Group 2 (P = 0.009). Regarding the storage medium, 17.1% of the individuals would keep the avulsed tooth in a dry medium. The majority of participants (58.3%) stated that the ideal extra-alveolar time for replantation was more than 360 min. Although 74% of the overall sample stated having knowledge of mouth guards, few reported making use or indicating the use of this piece of equipment. The present study revealed that the majority of teachers and undergraduate students of physical education courses do not have adequate knowledge regarding first-aid measures for tooth avulsion and do not use or indicate the use of mouth guards during sports activities.
牙脱位后的急救措施以及预防性使用口腔防护用具。样本由 442 人组成（第 1 组：53 名教师；第 2 组：389 名大学生）。通过问卷调查收集数据，问卷既有客观问题也有主观问题，涉及定义、脱位和牙再植的急救措施，以及口腔防护用具的使用和指征评估。数据分析采用描述性统计和卡方检验。结果显示，两组参与者中，45.1%的人知道什么是牙再植。然而，91.6%的人认为自己无法立即进行再植。在总体样本中，45.9%的人对牙脱位的急救措施一无所知；将脱位的牙齿患者送到牙医处是最常被提及的措施（42.3%）。第 1 组中有 20.6%的人、第 2 组中有 5.9%的人提到立即再植（P=0.009）。关于储存介质，17.1%的人会将脱位的牙齿放在干燥的介质中。大多数参与者（58.3%）表示，再植的理想牙槽外时间超过 360 分钟。尽管 74%的总体样本表示了解口腔防护用具，但很少有人报告使用或表示在运动中使用该设备。本研究表明，大多数体育课程的教师和大学生对牙脱位的急救措施没有足够的了解，也不使用或表示在运动中使用口腔防护用具。
