Which statement best describes the goal of regenerative endodontics in immature teeth?

• A. Regenerate pulp-like tissue and allow continued root development
• B. Create a hard tissue barrier at the apex
• C. Achieve immediate obturation
• D. Remove all pulp tissue

Answer: (A)

Regenerative endodontics in immature teeth aims to re-establish a vital, pulp-like tissue inside the canal so the tooth can continue its natural development. The best way to describe this goal is to regenerate pulp-like tissue and allow continued root development, including continued root lengthening and thickening of the dentin walls. This approach uses disinfection while preserving or enabling a vascularized tissue to form inside the canal, often aided by bleeding from the apical papilla to bring stem cells and growth factors into the space, so the tooth matures rather than simply being filled. This is different from forming a hard tissue barrier at the apex, which is the aim of apexification and does not promote ongoing root development or restoration of vitality. It’s also not about immediate obturation or removing all pulp tissue; the regenerative goal centers on tissue regeneration and restoration of a functional pulp–dentin complex to support continued natural tooth growth.
