Dental trauma injuries during childhood may have an adverse impact on oral health throughout life. If trauma injuries causes pulpal necrosis, then the root stop forming. These teeth have consequently a questionable long-term survival. Dental management of necrotic teeth with aberrant root formation represents a challenging clinical situation. The classical approach for treating these teeth includes apexification. Both apexification with Calcium hydroxide and MTA do not achieve the goals of continued root development or restoration of pulp tissue functionality. In the last decades, a biological based approach referred as "revascularization", or "regeneration" has emerged as a biological treatment for necrotic pulps with aberrant root development. This treatment aims to regenerate pulp-like tissue within the root canal space after inducing an influx of stem cells from the apical papilla that results in reestablishment of pulp protective functions. There is evidence supporting the regeneration potential of dental tissues after regenerative endodontic treatment. However, root formation in traumatized immature teeth seems variable. The overall goal of this study is to gain knowledge about the treatment of immature necrotic teeth in young individuals due to dental trauma. The primary goal is to compare volumetric hard tissue formation between the MTA apexification and the regeneration treatment.
