Treatment of a non‐vital immature incisor with mineral trioxide aggregate (MTA)

– A case of severe crown fracture and luxation in the upper permanent incisors of a 9‐year‐old boy is reported. The treatment of one of the injured teeth included apexification with calcium hydroxide and endodontic treatment with gutta‐percha obturation. The other incisor was also treated with calcium hydroxide, but as there was no apical stop after 3 years of treatment, it was decided to use a new root‐end filling material: mineral trioxide aggregate (MTA). At follow‐up 12 months later, the tooth was asymptomatic and radiographically showed the initial repair of the radiolucent apical lesion.
