Avulsions are very common in a school setting. Teachers are often requested to help in such emergency situations. A survey consisting of seven simple questions regarding dental avulsion was answered by 60 teachers from five different elementary schools in Rio de Janeiro, Brazil, in order to evaluate their knowledge on the subject and establish a guideline to be followed when an accident of this type happens. A lack of technical information was observed among the teachers; most of them answered intuitively rather than on an informative basis. This study showed the need of a more effective communication between dental professionals and school teachers in order to better handle dental emergencies.
