Root lengthening with apical closure in two maxillary immature permanent central incisors after placement of mineral trioxide aggregate (MTA) as an apical plug

Necrosis of permanent immature teeth is a common reason for consultation in paediatric dentistry. Apexification is a therapeutic procedure aiming to create an apical calcified barrier in open apex teeth.
Two cases are presented in which apexification were completed on immature permanent traumatised incisors using a mineral trioxide aggregate (MTA) plug.
At 2 and 5 years showed apical closure and radicular elongation beyond the MTA plug.
Unexpectedly, a regeneration of mineral tissues beyond the MTA plug occurred which is an uncommon outcome.
