Non-Vital Decoronation of a Maxillary Central Incisor: A Case Report With 18 Months Follow-Up.

In the present case, decoronation and root submergence of a necrotic maxillary central incisor were performed for a 13-year-old girl. The root canal was filled with mineral trioxide aggregate (MTA), which was covered with resin-modified glass ionomer. Apexification with MTA was performed for her other maxillary central incisor, and the edentulous region was restored using a fiber-reinforced composite bridge. Long-term follow-up indicated that decoronation might be a viable option to maintain the alveolar bone.
