The aim of the study was to evaluate the knowledge of dental trauma management in the southern part of Hungary among parents, teachers, medical doctors and dentists. A cross-sectional study was performed among the mentioned groups, with a structured questionnaire. The participants consisted of 275 people, most of them were parents (185), the other groups were smaller (30-30). 73.62% of parents recognised that the maxillary incisor of a 9-year-old girl is probably a permanent tooth. In case of the coronal fracture of this tooth 65.03% responded correctly. The correct response rate for the management of an avulsed tooth was only 39.26%, but in case of loss of consciousness 92.64% would act correctly. The Chi-square test indicated that there was a significant association between the correct recognition of the type of incisor and higher education (p < 0.01), and the number of seen TDIs. The 76.7% of the parents was not satisfied with his knowledge about TDLs, and 74.9% was interested in more information. In our study the parents performed generally better compared to other studies, but compared to the other three groups their results were worse. The knowledge of the teachers and the doctors was almost equivalent. The dentist had the best results. The level of knowledge of dental trauma management was inadequate among parents, but the teachers and doctors should improve their knowledge too. We suggest that it's necessary to start educational campaigns among groups that could be the primary caregivers of traumatic dental injuries.
