This report compares the manner in which the avulsed tooth was handled at home versus at school, and presents the different outcomes of the replanted teeth in both groups. Eighteen of 32 avulsed teeth were not replanted, and four replanted teeth could not be followed. Thus, the material comprised 10 avulsed permanent incisors of 10 traumatized children, aged between 8 and 13 years, who were treated at the Pediatric Dental Clinic of Niigata University Dental Hospital. Half of the patients avulsed the tooth at school and the other half at or near home. Of the five teeth avulsed at school, three were kept under wet conditions. The time until their replantation ranged between 0.5 and 3.5 h. Their outcomes were fairly good, except for one incisor that was extracted about 3 years later owing to the undesirable replantation procedures by the dentist. Of the avulsed teeth at or near home, three were left under dry conditions. Their time until replantation ranged scattered between 0.5 and 12 h. Of these, two incisors preserved under wet conditions survived without significant root resorption. These results suggested that information about the way to keep the avulsed tooth was relatively well known to school nurse-teachers compared with parents. Depending on the kind of lay people, it appears that it is necessary to select the best way to convey information about the management of avulsed permanent teeth.
