Healing process after root canal therapy in immature human teeth: Bibliographycal review

This bibliographical research has investigated the healing process after root canal therapy in immature human teeth. Although there is still uncertainty about the histological mechanism of the treatment and there is a controversial explanation in literature, the authors asseverate that the apical limit can be formed by two tissues: dentine or cementum. The healing process has been studied and characterized by the appearance of radiopaque tissue on the apicalregion or by the complementation of radicular development with hard apical tissue deposition. In this case the root of the teeth may present several forms. The most commonly used substance in the treatment is calcium hydroxide.Some researchers say that the apical closure may occur when the infection is controlled and in the absence of an inductive substance of mineralized tissue.
