Introduction: Tooth injuries are the most common among children and are usually caused by a direct blow. Tooth avulsion is one of the most urgent tooth injuries. Appropriate measures in the field of first aid are crucial for a successful outcome of treatment, in addition to the time that has elapsed from the injury to the insertion into the tooth socket. Purpose: The purpose of the thesis is to find out whether laypeople know the first aid procedures for tooth injuries, whether they have been acquainted with the first aid course and whether they know the correct media in which they can store a knocked out tooth. Methods: First, a literature review was made. The empirical part consists of an experimental method, where data on first aid knowledge of tooth injury have been collected with a practical test in a simulated case of tooth damage. In order to perform the experiment, we created a model of the face with a knocked up tooth and made a video showing the tooth injury incident. Participants in the survey were asked to perform first aid procedures after watching the video, with a first aid kit available. The procedures obtained were evaluated using a developed evaluation assessment sheet. We conducted 100 practical tests where random passers-by of different ages, gender and education were selected. Results: In the survey, 11 % of participants wore protective gloves, 25 % of them touched the tooth for the crown, 96 % of the participants did not replant the tooth, 67 % of which stored the tooth in an incorrect medium. 20 % of the participants would have directed the injured person to the dentist. Discussion and conclusion: The survey shows that people did not receive enough information on the topic of first aid for tooth injuries. The majority of participants in the study are aware that it is necessary to help an injured person and stop the bleeding, but they do not provide the necessary safety, for example, use of protective gloves from the first aid kit. The majority of people involved in the study picked up the tooth incorrectly. It is urgent to pick it up by the crown and not the root because there are periodontal ligaments that are very important for replanting tooth into the tooth socket. The best replantation survival have teeth that are outside the tooth socket for less than 5 minutes, therefore efforts should be made to insert the tooth shortly after the injury. Knowing the right procedures of first aid for tooth injuries and media for storing a knocked out tooth plays a key role in the effectiveness of rehabilitation.
