title: [Clinical effect of reattachment of permanent anterior teeth with crown fracture].
abstract: OBJECTIVE
  To compare the clinical effect between reattachment of permanent anterior teeth with crown fracture using dual-cured resin combined with dentin pin and conventional method.
  
  
  METHODS
  49 permanent anterior teeth of 38 patients which had intact incisal edge segments were divided into two groups. In experimental group reattachment was conducted by dual-cured resin combined with dentin pin, while in control group only dual-cured resin was adopted. Cases were assessed clinically by one year's followed up.
  
  
  RESULTS
  The success rate was 95% in experimental group and 64% in control group after one-year's follow-up (P < 0.05).
  
  
  CONCLUSIONS
  The clinical effect of reattachment with dual-cured resin combined dentin pin to treat anterior crown fracture is superior to conventional method.
