title: Apexogenesis treatment with a new endodontic cement: a case report.
abstract: BACKGROUND
  This article describes an apexogenesis report of an 8-year old boy referred to our clinic 4 weeks after an impact trauma to the maxillary left central incisor that caused a complicated crown fracture and pulpal exposure.
  
  
  METHODS
  In the radiographic examination, the tooth was observed to be immature. After access cavity preparation, cervical pulpotomy was performed, and the remaining pulp was capped with calcium enriched mixture (CEM) cement. The crown was restored by using the fractured incisal segment on the next day.
  
  
  RESULTS
  The radiographic and clinical examinations on the 6-month and 12-month follow-ups showed that the tooth remained functional, root development was completed, and the apex was formed. A calcified bridge was produced underneath the capping material. No further endodontic intervention was necessary.
  
  
  CONCLUSIONS
  Considering the healing potential of traumatized immature vital pulp, the use of CEM cement for apexogenesis might be an applicable choice; however, further clinical studies with longer follow-up periods are recommended.
