Revascularization (regenerative endodontic treatment) is generally preferred over traditional apexification for necrotic young permanent teeth because it allows for continued root development, increasing root length and dentin thickness.
The retrieved literature consistently shows that while both revascularization and apexification exhibit high overall success and survival rates in managing necrotic immature permanent teeth, revascularization (regenerative endodontic treatment, or RET) is increasingly preferred because it promotes continued root maturation (increased root length, width, and radiographic root area), whereas conventional apexification merely creates an apical barrier without further root development.
