Correct answer: D — Regenerative endodontic procedure (revascularisation)

For a necrotic immature permanent tooth with an open apex, regenerative endodontic procedures (REPs/revascularisation) are now the preferred treatment approach (AAE, 2018). The protocol involves disinfection of the canal (NaOCl irrigation, triple antibiotic paste or calcium hydroxide medicament), followed by induction of bleeding from the periapical tissues into the canal to create a blood clot scaffold, sealed with MTA and composite. REPs aim to achieve continued root development (thickening and lengthening), which is superior to apexification (which only creates an apical barrier).
