title: A long-term retrospective clinical study on MTA pulpotomies in immature permanent incisors with complicated crown fractures.
abstract: OBJECTIVE
  The study was undertaken to evaluate mineral trioxide aggregate (MTA) clinically and radiographically as a pulpotomy agent in immature permanent teeth whose pulps were exposed by a complicated crown fracture.
  
  
  METHODS
  Thirty incisors with exposed pulps in twenty-nine patients were examined for this retrospective study. According to exclusion criteria, only twenty-seven teeth were selected. Each tooth was treated with partial pulpotomy and the wounded pulp was covered with mineral trioxide aggregate. The children were recalled for clinical and radiographic evaluation at 3 months, 6 months, at approximately 12 months and 36 months.
  
  
  RESULTS
  Out of 27 cases, 22 were categorized as 'healed' and 1 as 'healing'. The remaining 4 ones highlighted persistent disease and needed further endodontic treatment.
  
  
  CONCLUSIONS
  MTA partial pulpotomy is an effective treatment in maintaining pulpal vitality and allowing physiological root development (apexogenesis).
