Aim: In this study aimed to evaluate the knowledge of 4th and 5th grade students of Dicle University Faculty of Medicine and Dentistry and their approach to first intervention in the face of avulsion, which is the one of the types of dentoalveolar injuries.Material and Method: 300 students selected by random sampling method among 4th and 5th grade students of Dicle University Faculty of Medicine and Dentistry. 17 questions and a questionnaire consisting of three parts were applied to the total of three hundred students from two faculties. The data obtained in this study were analyzed with IBM SPSS 21 package program. While interpreting the results, 0.05 was used as the significance level.Results: There is a statistically significant relationship between the faculty and the previous trauma/emergency or first aid course status (p <0.05). While 34% of the medical school and 86.67% of the dental students had not taken a trauma/emergency or first aid course before, 66% of the medicine faculty and 13.33% of the dentistry faculty have previously taken a trauma/ emergency or first aid course. There is a statistically significant correlation between gender and previous trauma/emergency or first aid course status (p <0.05). While 76.64% of women and 51.3% of men had not taken traum /emergency or first aid courses before; 23.36% of women and 48.7% of men have previously received a trauma/emergency or first aid course. Conclusion:According to this study, it is thought that the medical and dental faculty students who came to the clinical stage of their education had insufficient knowledge about dental trauma, so it would be appropriate to provide dental health information with more comprehensive and understandable way in the education curriculum of the faculties. It will be appropriate to give interdisciplinary seminars, case presentations and lectures on practical emergency response on dental trauma.
