title: [Clinical evaluation of two canal obturation materials in treatment of periapical periodontitis in deciduous teeth].
abstract: OBJECTIVE
  To analyze the clinical effects of 283 deciduous teeth which suffered from periapical periodontitis and sinus in 179 children from the year of 2001 to 2004.
  
  
  METHODS
  In all the 283 teeth, the root canal of 196 teeth were obturated with paste zinc oxide-eugenal; the other 87 teeth were obturated with Vitapex. The signs,symptoms and radiographs of these teeth were evaluated at 3 and 12 months after treatment.
  
  
  RESULTS
  The successful rate was over 96.0% in both treatment groups.
  
  
  CONCLUSIONS
  Most of deciduous teeth which suffered from periapical periodontitis and sinus could be preserved if adequate indications were taken and treated in time.
