Abstract

Root canal treatment of immature permanent teeth with pulp necrosis presents clinical difficulties due to wide root canals and apical foramen. In addition, there is a high risk associated with a potential cervical fracture due to the thin dentinal walls even after successful root canal treatment. Thus, a notion of continued root development of the immature tooth has continuously explored. Regenerative endodontic treatment (RET) provides a biological treatment approach based on regeneration and revascularization principles. Unlike conventional apexification, RET promotes the growth and development of immature roots and the healing of the periapical lesion via disinfection of the infected root canal system. Therefore, RET may provide a positive effect on the long-term prognosis of immature permanent teeth with pulp necrosis.
