This case report aimed to present the long-term clinical performance of mineral trioxide
aggregate (MTA) pulpotomies in immature permanent teeth. Four patients with complicated
crown fractures of five maxillary immature central incisor teeth were treated with
pulpotomy using gray MTA. An immature mandibular first molar showing signs of reversible
pulpitis that was exposed mechanically during cavity preparation was also treated
with MTA pulpotomy. Four of the 6 immature teeth were diagnosed vitally with complete
root maturation and with the presence of dentin bridges after 55 months (mean time
of follow-ups). MTA pulpotomy was assessed unsuccessfully in two fractured central
incisors. Severe discoloration in the crowns was present in all 6 cases. MTA may induce
pulp healing with dentin bridge formation and prevent necrosis at long-term periods
in most of the pulpotomy cases. However, discoloration following MTA pulpotomy is
a significant clinical complication. (Eur J Dent 2013;7:133-138)
