title: [Comparison of the clinical efficacy of self-etching bond system and composite resin in repair of dental defects].
abstract: OBJECTIVE
  To compare the efficacy of self-etching bond system and composite resin in repair of dental defects.
  
  
  METHODS
  201 teeth were randomly divided into two groups. 101 teeth in the experimental group were treated with CLEARFIL self-etching bond and AP-X to repair dental defects, while 100 teeth in the control group were treated with Durafill bond and Charisma. 201 teeth were followed up for 1,3,6 months, respectively. The date was analyzed by Chi square test.
  
  
  RESULTS
  The result showed that the successful effective rate of the experimental group (98%) was significantly higher than that of the control group (90%, P<0.05) statistically.
  
  
  CONCLUSIONS
  Using of self-etching bond system and composite resin to repair dental defects has indicated perfect retention and marginal sealing, which is worthy of wide clinical application.
