Purpose: To evaluate dentists' professional experience and knowledge of emergency management of tooth avulsion injuries in Rio de Janeiro, Brazil. Materials and Methods: A total of 100 questionnaires were evaluated. The first part of the questionnaire consisted of questions regarding personal information. The second part evaluated dentists' knowledge of emergency management in cases of dental avulsion. The responses for each question were counted and expressed as percentages. Results: All dentists had a college degree or above. Only three dentists had a Master's or PhD degree. Most of the dentists (94.5%) considered time and storage media important for the prognosis of avulsed teeth. However, the dentists did not show consistent responses about the adequate time and ideal storage media to transport avulsed teeth. Conclusion: The study highlighted Brazilian dentists' need for continuing education in order to improve current knowledge in emergency management of avulsed teeth.
