Considerations for Regeneration Procedures

When pulp tissue becomes necrotic in immature teeth, the prognosis of the teeth is compromised. Disinfection of the root(s) presents several challenges including difficulties in cleaning and shaping large canals with open apices, obturation of canals with open apices, and potential root fractures caused by thin and/or weakened root walls. Regenerative endodontic procedures may increase the prognosis of the compromised immature tooth by re-establishment of a functional pulp tissue that fosters continued root development and immune competency. This article reviews the literature related to and discuss considerations for regenerative endodontic procedures and how these procedures may increase the prognosis for immature teeth with necrotic pulp tissue.
