ENDO 1 – Procedure Management, Records, and Clinical Cases Practice Test

In immature teeth with an open apex, the key distinction lies in the goal: apexification seeks to create a stable apical barrier so the canal can be obturated, often using calcium hydroxide or MTA. Regenerative endodontics aims to regenerate pulp-like tissue and promote continued root development, potentially lengthening the root and thickening canal walls. Because of these different aims, the steps differ: disinfection strategies are chosen to protect stem cells and support healing, the placement approach often employs a scaffold such as a blood clot to support tissue ingrowth, and the overall environment is dynamic, allowing ongoing root maturation rather than a fixed barrier alone. This statement correctly contrasts the two approaches by pairing the barrier-formation objective with the regeneration-and-growth objective and noting the procedural distinctions that follow. The other options misstate either the goals (suggesting both attempt to regenerate pulp-like tissue) or the applicability to immature teeth (regenerative endodontics is indeed used to promote root development in immature teeth).
