title: [Clinical study on glass fiber-reinforced post applied in the restoration of residual crown and root of posterior teeth].
abstract: OBJECTIVE
  The aim of this prospective randomized controlled trial is to evaluate the clinical effect of glass fiber-reinforced post core applied in the restoration of premolar or molar residual crown and root.
  
  
  METHODS
  195 residual crown and root of posterior teeth from 100 patients, aged from 18 to 60 years, were included in the study. Among 195 teeth, 95 teeth in the experimental group were restored with glass fiber-reinforced post core, while the other 100 teeth in the control group were restored with metal cast post core. All the teeth were then restored with porcelain fused metal crown. The esthetical property, function, and survival rate of the prostheses were observed. The data was analyzed with SPSS13.0 software package for X(2) test.
  
  
  RESULTS
  The prostheses were followed up in this clinical study for a period of up to 36 months. In the experimental group, there were a total of 90 teeth with excellent chewing function, no complaint of discomfort, no debounding, no gingivitis or periapical periodontitis. The success rate of the experimental group was 94.74%, while that of the control group was 85.00%. The difference of the success rate between two groups was statistically significant(P<0.05).
  
  
  CONCLUSIONS
  Glass fiber-reinforced post core can be used as an ideal restoration material for the premolar or molar residual crown and root.
