Objectives: The objective of this study was to assess the present knowledge level of emergency measures for tooth avulsion in schoolchildren with sports education in Sivas. Materials and Methods: A total of 112 schoolchildren aged 15-18 years old, were interviewed bu professionals using a standardized method to score knowledge about tooth avulsion and replantation. The following fields of knowledge were assessed tooth avulsion and replantation principles, avulsed permanent/primary teeth, cleaning of avulsed tooth before replantation, extra alveolar time and storage media. Chi-square test was used for statistical analysis. Results: Regardless of age group, there were generally a low knowledge level regarding tooth avulsion, replantation, extra alveolar time and storage media. When comparing special knowledge level of the avulsion and replantation of the permanent/primary teeth according to the age groups, the differences between age groups were found statistically important. 16 and 17 age groups had middle knowledge level. The lowest knowledge level was in 15 age group. Concerning with storage media, 60,4% of students preferred water and 11,4% of students preferred milk for storage media. Conclusions: We conclude that first-aid knowledge in schoolchildren with sports education is low on avulsion and replantation of teeth and the knowledge level of first-aid measures on avulsion and replantation of teeth could be increased through intervention programs.
