title: [Treatment of vertically fractured teeth with Vitapex and post-core crown].
abstract: OBJECTIVE
  To study the possibility of treatments of vertically fractured teeth with Vitapex and post-core crown.
  
  
  METHODS
  29 vertically fractured teeth were involved in this study, all the traumatized teeth were treated with Vitapex to control the furcation involvement and accelerate the healing of bone tissue, with root canal therapy and post-core crown to fix. The clinical effects were investigated in the following 30 to 42 months. The restorative results were evaluated with clinical examination, radiological examination and chief complaints of the patients.The data were analyzed with SPSS10.0 software package for Chi-square test.
  
  
  RESULTS
  The outcomes of restorations in 27 teeth were satisfactory. The success rate was 93.1%. Only two restorations were failed due to severe periodontitis and refracture. The difference between the groups was statistically significant based on different times to treat after fracture (<1 day, 1 day-7 days, 8-30 days). The results demonstrated that the earlier to treat the fractured teeth, the better results we got.
  
  
  CONCLUSIONS
  Vitapex and post-core crown is a promising therapy for vertically fractured teeth.
