Abstract
|
|
|
|
As long as the pulp vitality is maintained, partial pulpotomy can promote healing of the necrotized pulp and induce root development in the treatment of immature permanent crowns which are fractured and have pulp exposure due to trauma. However, mineral trioxide aggregate (MTA) is commonly used in this technique due to its superior sealing effect, but the disadvantage of discoloration when used for the anterior teeth still persists. In this case study, for prevention of tooth discoloration following regenerative root canal treatment, Retro MTA was used as an alternative for MTA. Retro MTA is made of zirconium aluminate cement, which replaces Portland cement used in MTA, which is thought to be the factor that induces discoloration. We report a successful case without any noticeable discoloration after applying Retro MTA, following partial pulpotomy.
