In case of luxation injuries, loss of tooth vitality is common. And in case of trauma in the immature permanent teeth, precise diagnosis of pulp necrosis is very difficult. That is because limitation in distinguishing between normal dental papilla in immature permanent teeth, transient apical breakdown(TAB), which is part of normal healing process, and apical radiolucency in pulp necrosis. Especially in non-vital immature permanent tooth, the treatment is complex and requires long time. This clinical case report shows that severely infected immature teeth with periradicular periodontitis can undergo healing and apexogenesis or maturogenesis with no definative treatment or after conservative treatment. In the cases reported, we emphasize the considerable power of regeneration of the tooth, probably due to its large number of undifferentiated mesenchymal cells in the dental papilla, pulp tissue, periodontal ligament tissues. Thus, when endodontic treatment in immature permanent teeth, over instrumentation is not recommend for preserve the apical vital stem cells.
