title: [Treatment of chronic apical periodontitis teeth complicated by open apices with Vitapex in the adults].
abstract: OBJECTIVE
  The aim of this study was to evaluate Vitapex (a premixed calcium hydroxide and iodoform paste) for treatment of chronic apical periodontitis complicated by incompletely developed apices in the adults.
  
  
  METHODS
  36 teeth with incompletely formed apices were selected. After the root canals were prepared and sterilized , Vitapex was used in the apexification. All the patients were followed-up clinically and radiographically 3 months and 10-18 months postoperatively. The root canal were then filled with Obtura II gutta-percha when the apical barrier could be detected.
  
  
  RESULTS
  A radiographic evaluation showed that 7(19.4%) teeth completed root development and apical closure. 27 (75%) teeth could be detected apical barrier. 2 (5.6%) teeth were failed. The overall success rate was 94.4%. The average period of the whole endodontic treatment was 13.0 weeks.
  
  
  CONCLUSIONS
  Vitapex is a good material in the treatment of chronic apical periodontitis complicated by incompletely formed apices in the adults.
