The aim of this study was to evaluate knowledge and self-reported  practice of senior medical students at Tehran University of Medical Sciences (TUMS) about managing tooth avulsion. Materials and Methods: This cross-sectional study evaluated the knowledge and self-reported  practice of senior medical students (n=150) in TUMS towards management of tooth avulsion. A standard anonymous questionnaire obtained from previous studies was distributed among  students. The questionnaire was consisted of questions on backgrounds (age, gender, previous encounter with tooth avulsion, previous education on management of traumatic dental injuries-TDIs); knowledge, and self-reported practice regarding tooth avulsion management; and satisfaction (self-competency, importance of educational programs, knowledge self-assessment, and willingness for further education). After collecting the questionnaires, the answers were scored and results were analyzed using descriptive statistics, linear regression model and Pearson correlation coefficient. Results: Totally, 126 questionnaires were collected (Response rate= 84%) of whom 49 (%38.9) were male and 77 (%61.1) were female, with the mean age 25.1±1.2. Previous encounter with tooth avulsion was reported by 18 students (14.3%). Only five students (%4) had received education regarding TDIs. The knowledge, and self-reported practice mean score were 3.82±1.29 (out of 12), and 4.44±0.7 (out of 8), respectively. None of background variables had a significant relationship with the knowledge, and self-reported practice mean scores. There was no correlation between students’ knowledge and self-reported practice. More than 97% of students reported low/very low self-competency for replantation of an avulsed tooth. Majority of the participants (%84.2) were dissatisfied with their level of knowledge and suggested that further education on the topic should be offered. Conclusion: The results indicated that there is a need to improve the knowledge of medical students regarding management of traumatic dental injuries. https://jcr.tums.ac.ir/index.php/jcr/article/view/267 https://jcr.tums.ac.ir/index.php/jcr/article/download/267/241
